1. Introduction

ByteStudio has developed a special solution for processing the digital television signals, where both the transmission of the high data rate transport stream and the control of the associated devices will be done over Ethernet network. The BS-GEC-4x Gigabit Ethernet Controller is a universal data transmission and device controller module for IP based digital television systems.

In the BS-GEC-4x the communication is handled by the IP

Manager. The IP Manager serves the connected four transport stream transmitter/receiver units of identical set-up and extremely high data rate. For the device control over the IP network, the module provides a serial and a parallel port, an I

2

C bus, an 8-bit selector port and an output for driving LEDs.

The board cannot accommodate all connectors of the four transmitter/receiver units therefore it is manufactured in two versions

(4I and 4O). The 4I version is equipped with 4 inputs, and it can process and pack in UDP/IP packets 4 transport streams coming from different sources. The 4O version is equipped with 4 outputs, and from the input gigabit data stream it can assemble 4 output transport streams upon the

IP addresses and Port numbers. The 4-input version is equipped also with a TS output of full value.

Gigabit Ethernet Controller operates in IPv4, but is already prepared to IPv6. Recognition of the systems with 10, 100 and 1000

Mbit/s data rate is automatic (Auto Negotiation), and the controller goes always to the applicable highest data rate full duplex mode. The controller handles the ARP and Ping instructions, and it is equipped with an ARP Advertisement function of programmable repetition time. Both the Primary and the Secondary MAC address of the module are programmable. The module is suitable for receiving and transmitting the transport stream in unicast and multicast systems alike; in multicast networks calling in the transport stream is made with IGMP messages.

The four transport stream sending units are equipped with own sync separator, null packet remover and packet clipper. The number of packets to be built in the UDP/IP packets is programmable between 1 and 7.

The controller handles the SNMP messages: each instruction of the instruction set can be built in SNMP messages and the error messages are delivered by sending SNMP Trap.

The instructions start with DDToIP (Digital Data Transmission over

IP) characters, after which the user can put a character series for the identification of his system.

Maximum current consumption: 600 mA.

4.2. Integrated 10/100/1000 Ethernet Interface

The Gigabit Ethernet Controller contains a Realtek RTL8211B integrated Ethernet transceiver that complies with 10Base-T, 100Base-

TX and 1000Base-T IEEE 802.3 standards. Realtek RTL8211B provides all the necessary physical layer functions to over CAT 5 UTP cable or CAT

3 UTP (10Mbps only) cable. The Ethernet interface configuration is the following:

• The Gigabit Ethernet Controller operates in full-duplex mode.

Although half-duplex mode is also advertised, working in fullduplex mode is supported only.

• Auto-Negotiation is enabled (advertise all capabilities, prefer Slave).

Auto-Negotiation is a mechanism to determine the fastest connection between two devices. The Gigabit Ethernet Controller can transmit and receive Ethernet packets at 10/100/1000Mbps link speed and Auto-Negotiation ensures that the highest priority protocol will be selected.

• Crossover Detection & Auto-Correction are enabled. Ethernet needs a crossover mechanism between both partners to cross the signal transmitted to the receiver when the medium is twisted-pair cable (e.g. CAT.5 UTP). Crossover Detection & Auto-Correction

Configuration eliminates the need for crossover cables between devices.

• The Gigabit Ethernet Controller automatically corrects polarity errors on the receive pairs in 1000Base-T and 10Base-T modes. In

100Base-TX polarity is irrelevant.

4.3. Device Management

Building the network and connecting the devices is made using the standard elements used in computer networks, no special elements or cables are required. For connecting a device UTP (Unshielded Twisted

Pair) cables of at least category 5 have to be used. The connections are made with RJ45 8-pin telephony connectors (Connector B). The Gigabit

Ethernet Controller supports only the „Full Duplex” mode.

The Gigabit Ethernet Controller can easily be programmed via

UDP/IP. Packets can contain one or more instructions. The device supports two instruction protocols:

• CW-Net (see 4.3.2.)

• Digital Data Transmission over IP (see 4.3.3.)

Gigabit Ethernet Controller supports several protocols that do not belong closely to the device management:

• It sends an answer to the ARP query (see RFC 826.).

• It sends an answer to the ICMP PING request (see RFC 792).

• It supports IGMPv2 messages (see RFC 2236).

4.3.1. IP and MAC Addresses

The Gigabit Ethernet Controller has two programmable MAC addresses and a programmable IP address.

Primary and secondary MAC addresses can be set using SETPMAC and SETSMAC instructions. The device supports two modes of setting primary MAC address:

• In Manual mode user can freely set the primary MAC address.

• In Auto mode the device automatically computes the primary MAC address from its IP address (figure 4). The firs two bytes of the

MAC address are constant 42:57 hexadecimal. The lower 4 bytes refer to the IPv4 address.

Figure 4. Auto MAC Mode

11



The secondary MAC address can be configured only manually. However the device receives packets addressed to its secondary MAC, in transmitted packets (e.g. ACK answer, ARP reply, SNMP Trap, TS packet) always the primary MAC address will be included. To disable the secondary MAC address set it to FF:FF:FF:FF:FF:FF.

The IP address can be configured with the SETIP instruction. In the instructions IP addresses are 16-byte long fields because of the IPv6 preparation. In IPv4 systems only the lower four bytes are used as an

IPv4 address. The upper 12 bytes must be set to zero. Note that the

Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private networks (see RFC 1918):

Network Address Range CIDR Notation

10.0.0.0 - 10.255.255.255

172.16.0.0 - 172.31.255.255

192.168.0.0 - 192.168.255.255

/8

/12

/16

Factory default settings (MAC addresses are given in hexadecimal format, IP address in decimal format):

• Primary MAC address:

42:57:0A:7B:0D:65

• Secondary MAC address:

FF:FF:FF:FF:FF:FF

• IP address:

10.123.13.101

When a packet is received the Packet Filter module (see the block diagram on figure 1.) examines its destination MAC address, size, type and destination UDP port (figure 5.):

• Passed MAC addresses (others are filtered):

1. Broadcast MAC (FF:FF:FF:FF:FF:FF)

2. Primary

3. MAC

4. Multicast MAC addresses, if the device is receiving multicast

Transport Stream (see RECEIVETS instruction). In this case

01:00:5E:00:00:01 MAC address (“all systems in the subnet”) is also passed.

• Packets with sizes lower than 60 bytes (without CRC) are filtered.

• ICMP Destination Unreachable packets are filtered.

• If a UDP packet is received and its destination port matches with one of the four TS output channel port the packet will be handled as a TS packet. TS output channel ports can be programmed or disabled using RECEIVETS and DONTRECEIVETS instructions.

Otherwise if the destination port is not within the TS Port interval the packet will be processed by the Message Processor. Packets

12



with destination port included in the TS Port interval are dedicated to be foreign TS packets and will be filtered. The TS Port interval can be programmed with the SETTSPORTINTERVAL instruction.

Figure 5. Packet Filter

The Gigabit Ethernet Controller has an ARP Advertising function. If the ARP Advertising function is on, the device periodically sends broadcast ARP reply messages (“the device is at its IP address”). It’s useful to refresh switches’ MAC address tables.

4.3.2. CW-Net Protocol

The CW-Net protocol was developed by CableWorld Ltd.. It performs both device control, data loading and continuous transmission of the transport stream using Ethernet networks and UDP/IPv4 protocol.

The Gigabit Ethernet Controller is fully compatible with the CW-Net system with the following restrictions:

• IPTV Option is always included.

• Only TS Channel 1 and NCO1 can be programmed via CW-Net.

• Only the lower 16 bits of the serial number can be set.

• Replace MAC instruction changes the Primary MAC Address.

• When using the Set Outputs instruction, Out1 port refers to

Selector and Out2 port refers to GPO. No clock signals are implemented.

4.3.3. DDToIP Protocol

Digital Data Transmission over IP (DDToIP) is a flexible device management protocol specially developed for the Gigabit Ethernet

13



Controller. The instructions are encapsulated in UDP/IP packets as shown in figure 6.

Figure 6. DDToIP Protocol

Data packets start with a standard 14-byte MAC frame (Ethernet header). The MAC frame structure is described in the IEEE 802.3 international standard. The first 6 bytes of the 14-byte Ethernet header carry the address of the device to receive, the next 6 bytes carry the address of the sender device. The last 2 bytes contain a length field or an

Ethernet type.

The Ethernet header is followed by an IPv4 or IPv6 header depending on the Ethernet type (0x0800 for IPv4 and 0x86DD for IPv6).

The length of the IPv4 header is generally 20 bytes; the IPv6 header’s is

40 bytes. IP header carries the destination’s IP address and the sender’s

IP address. Details are described in RFC 768 and RFC 2460.

The UDP header consists of 8 bytes. The structure of the UDP header is described in RFC 768. It contains the source and destination port numbers.

The Ethernet packets are closed with a 4-byte CRC.

The UDP payload must start with “DDToIP” characters (44-44-54-

6F-49-50 hexadecimal). It is followed by a 15-character user-defined

14



string (User Text). You can use this field to place your company name into the UDP packet. V (version number) must be 0x01.

The DDToIP packet can contain one or more instructions.

Instructions are performed sequentially. Details are described in section

5.

4.3.4. Network Mask and Default Gateway

The network address space is usually organized into several subnets. Routers (default gateways) constitute borders between subnets.

In IPv4, the subnet is identified by its base address and network mask.

The network mask and default gateway are used only when a SENDTS instruction is processed (to determine the Transport Stream’s destination).

While network masks are represented in dot-decimal form their use becomes clearer in binary. Looking at a network address and a network mask in binary the device can determine which part of the address is the network address and which part is the host address. To do this, it performs a bitwise "AND" operation. Network masks consist of a series of 1s in binary followed by 0s. The 1s designate that part of the address as being part of the network portion and the 0s designate that part as being part of the host address. If the Transport Stream’s destination address belongs to some place outside the local subnet, the

Gigabit Ethernet Controller sends packets to the destination through the default gateway. The network mask can be programmed using the

SETNETMASK instruction. The factory default value is 255.0.0.0.

A default gateway is a node (a router) on a network that serves as an access point to another network. A default gateway is used by the device when a Transport Stream packet's destination address is outside the local subnet. Let’s see an example:

Device IP: 10.123.13.101

Network mask: 255.0.0.0

Default 10.123.13.1

Destination A: 10.14.5.6

Destination B: 192.168.1.6

The local IP address range is 10.0.0.0 to 10.255.255.255. The device will send packets addressed to IPs within this range directly (Destination A), by resolving the destination IP address into a MAC address through an

ARP sequence. Packets addressed outside of this range, in the example a packet addressed to 192.168.1.6, are sent to the default gateway address, in this case to 10.123.13.1, which is resolved into a MAC

15



address as usual. Note that the destination IP address will remain

192.168.1.6, it is just the next-hop physical address that is used, in this case it will be the router's interface physical address.

The Default gateway can be programmed using the SETGATEWAY instruction. The device supports two gateway modes:

• Off: There is no default gateway in the network. Packets will be sent directly to destination (factory default setting).

• Manual: User sets the gateway IP’s. The gateway MAC address will be found by the device using ARP sequence.

4.3. Transport Stream Inputs

Version 2.00


The Gigabit Ethernet Controller model 4I (GEC-4I) has four independent Transport Stream (TS) input channels and one Transport

Stream output channel. Model 4O (GEC-4O) hasn’t got any inputs.

The GEC-4I TS input channels are the TS1, TS2, TS3 and TS4 connectors.

Each Transport Stream input channel has an 8-bit data bus (TS

Data 0-7) and control signals: TS Clock, TS Data Valid and Reset.

• TS Clock runs at the rate at which bytes are offered to the device on TS Data 0-7. Data will be sampled (so it must be stable) on the rising edge of the clock signal. TS Clock frequency must be between 0 and 27MHz.

• If Data Valid pin is enabled (see SENDTS instruction), TS Data

Valid indicates valid data bytes on TS Data 0-7. TS Data Valid must be at logic 1 for the whole duration of the transport packet. It could go to logic 0 for one or more byte times to indicate data bytes, which should be ignored.

• Reset (active low) is logic 0 during system reset (see RESET instruction).

The Transport Stream input channel converts the input stream to

UDP/IP packets (figure 7.). The process depends on the configuration bits (blue text in figure 7.) in the SENDTS instruction.

• If the Data Valid pin is enabled (DV = 1) data bytes are ignored while TS Data Valid pin is at logic 0. Otherwise every data byte will be processed.

• FRMT bit determines how to encapsulate the TS stream to UDP/IP packets. The Gigabit Ethernet Controller supports IPTV format and

CW-Net format.

• In case of CW-Net format the UDP header is followed by n TS data bytes depending on the value of CWNetSize. CWNetSize must be between 128 and 1440. The UDP payload is closed by a 32 byte

CW frame, which contains the time stamp of the 125 MHz system clock (PCR), the continuity counter and the ‘CW-Net’ text (figure

8.). PCR is encoding timing information as 32 bits of the 125 MHz system clock frequency divided by 5 plus 3 bits for the remainder.

PCR Low is an 8 bit field and counts from 0 to 4. PCR High is a 32 bit field.

18



PCR(i) = PCR High(i) * 5 + PCR Low (i)

PCR indicates the intended time of the arrival of the first data byte in the packet at the TS input channel.

Note: Because of technical reasons CWNetSize shall not be N*188-32 or N*204-32 (where N is an integer between 1 and 7) if you would like to receive the IP stream with another Gigabit Ethernet Controller!

These sizes are reserved for IPTV format packets.

• In case of IPTV format (after sync separation) null packets and packets with Transport Error Indicator flag set to ‘1’ are being removed if the RNP and RTSP bits are set. The format converter set the TS packets to 188 (TSF = 0) or 204 (TSF = 1) bytes in length.

The number of TS packets to be built in the UDP/IP packets is programmable between 1 and 7 (NUMOFPACKET).

Figure 7. TS input to UDP/IP process

19



Figure 8. CW frame

The controller starts sending UDP encapsulated TS packets when a

SENDTS instruction is received and it stops sending TS when a

DONTSENDTS instruction is received or power is off. If the ALWY bit in the SENDTS instruction was set (‘1’) the controller automatically starts sending TS after a power on state.

The UDP/IP packets can be addressed to the following destinations

(DESTMODE):

• Send TS to Me: Controller sends TS packets to the host computer.

Only the destination UDP port should be set in SENDTS instruction.

• Send to Broadcast: Controller sends TS packets to a broadcast address, which is computed from the device’s IP address and the network mask (e.g. IP: 10.123.13.101, Network mask: 255.0.0.0,

Broadcast address: 10.255.255.255). The destination MAC address will be FF:FF:FF:FF:FF:FF.

• Send TS to IP: Controller sends TS packets to the selected IP address. The controller sends TS packets addressed to IPs within the local network range directly, by resolving the destination IP address into a MAC address through an ARP sequence. Packets addressed outside of this range are sent to the default gateway address, which is resolved into a MAC address as usual.

Destination UDP port and IP address should be set in SENDTS instruction.

• Send TS to Multicast: Controller sends TS packets to the selected multicast IP address. Multicast MAC address is automatically computed from the IP address. Destination UDP port and IP address should be set in SENDTS instruction.

• Send TS to Manual: Controller sends TS packets to the selected manual address. All destination UDP port, IP address and MAC address should be set in SENDTS instruction.

4.4. Transport Stream Outputs

The Gigabit Ethernet Controller model 4O (GEC-4O) has four independent Transport Stream output channels; model 4I (GEC-4I) has one Transport Stream output channel.

GEC-4O TS output channels are TS0, TS1, TS2, TS3 and TS4 connectors. TS0 and TS1 are the same outputs. GEC-4I TS output channel is the TS0 connector.

The Transport Stream output channel has an 8-bit data bus (TS

Data 0-7) and control signals: TS Clock, TS Data Valid and Reset. TS

Clock frequency refers to NCO frequency. Data changes on the falling edge of the clock signal.

If Data Valid pin is enabled (see RECEIVETS instruction), TS Data

Valid indicates valid data bytes on TS Data 0-7. TS Data Valid is at logic

21



1 for the whole duration of the transport packet and goes to logic 0 during ignored data bytes.

Reset (active low) is logic 0 during system reset (see RESET instruction).

The controller starts receiving TS (Output Channel becomes active, port filter is enabled) after a RECEIVETS instruction is received. For receiving multicast TS the user must set the multicast IP address of the stream and the UDP port number. For receiving normal TS the user must set the UDP port only. The TS Output Channel will be disabled when a

DONTRECEIVETS instruction is received (‘disabled’ means that all output pins are forced to be low).

Figure 9. TS Output Channel

Figure 9. shows the block diagram of the TS Output Channel. The function depends on the configuration bits (blue text in figure 9.) in the

RECEIVETS instruction. The Port filter selects the correspondent IP stream. The Sync Separator removes null packets and packets with TSP

Error flag set to 1 depending on the state of the RNIP and RTIP bits. The

IP stream is written into the FIFO Memory, which can store 23 packets at a time. If an overflow event occurs the overflow LED lights up and a trap

22



message is sent to the host computer (when this function is enabled).

Every TS Output Channel has a user programmable Output Formatter.

The Output Formatter contains a Null Packet Inserter (to generate continuous stream) a Packet Formatter (188 or 204 bytes) and a Clock

Signal Manager (it generates Data Valid signal and gated clock signal).

The TS output data rate can be programmed using SETNCO instruction.

4.6. NCOs

The Gigabit Ethernet Controller has 4 independent user programmable Numeric Controlled Oscillators (NCO). Frequency can be set between 120 Hz and 62.5 MHz in 1Hz steps. The NCO frequency is derived from the 125 MHz (50 ppm) system clock. The jitter depends on the division ratio.

NCOs generate clock signals to Transport Stream output channels.

Each NCO has an individual connector on the board (M,N,O and P on the block diagram), so all the 4 NCOs can be used in GEC-4I models too.

Frequency can be set using SETNCO instruction.

4.7. Parallel Data Interface

The Gigabit Ethernet Controller has a high data rate two-way parallel port (Connector H), through which data can directly be loaded from IP to the device or from the device to IP. Several slave devices can be connected to the bus (figure 10).

Figure 10. PDI Bus Structure

The Parallel Data Interface (PDI) has an 8-bit bi-directional data bus (DATA 0-7) and control signals: Clock (CLK), Transfer Enable (TE),

R/W, IRQ, WAIT and RESET.

The 8-bit data bus (DATA) is a bi-directional bus, connected to the positive supply voltage (3.3 V) through a pull-up resistor (2.2 kΩ on each line). When the bus is free, lines are HIGH. The output stages of the slave devices connected to the bus must have an open-drain or open-collector to perform the wired-AND function.

CLK, TE, R/W and RESET signals are outputs generated by the

Controller. WAIT and IRQ signals are inputs, connected to the positive supply voltage (3,3 V) through a pull-up resistor (2.2 kΩ).

A Read or a Write operation on the Parallel Data Interface can be performed using PDIREAD or PDIWRITE instructions. Both Read and

Write operation start with an address sequence. The controller writes the

8-bit Address and the 32-bit Subaddress to the bus while TE signal is

HIGH. Address and Subaddress are used to select the slave device and the memory range. Address sequence is followed by reading or writing the number of data bytes determined in the instruction. Operation is closed by a STOP condition (a LOW to HIGH transition (rising edge) on the CLK line while TE is LOW defines a STOP condition).

The WAIT signal can be asserted by any slave device to delay completion of the current access cycle.

26



Figure 10. PDI Reset and IRQ

A HIGH to LOW transition on the IRQ signal generates an interrupt in the Controller (figure 10). An IRQ message (see section 6.12.) will be sent to host computer.

4.7.1. Write Operation

During write operation the Controller drives the data lines. The data on the DATA lines must be stable during the HIGH period of the clock. The HIGH or LOW state of the data line will only change when the clock signal on the CLK line is LOW.

The WAIT signal can be asserted by the slave device when CLK is

HIGH. The controller samples the WAIT line after the falling edge of the

CLK and stops operation until WAIT returns to high or a timeout condition exceeds.

Write sequence is the following (figure 11.):

• Transfer Enable (TE) signal goes to HIGH and remains in HIGH state during the whole write operation. R/W signal remains in

LOW state.

• Controller writes Address and Subaddress (address sequence).

Slave devices sample the data bus on the rising edge of the clock.

• Controller writes data bytes.

• Transfer Enable (TE) signal returns to LOW. A clock cycle is generated while TE is LOW (STOP condition).

4.7.2. Read Operation

During read operation the Controller drives the data lines only when writing Address and Subaddress. After the address sequence the

Controller lets data lines go high impedance state. While reading data bytes slave device must drive the data bus. Controller samples the bus on the falling edge of the CLK. The data on the DATA lines must be stable during the LOW period of the clock.

After the address sequence WAIT signal can be asserted by the slave device when CLK is LOW.

Read sequence is the following (figure 12.):

• Transfer Enable (TE) signal goes to HIGH and remains in HIGH state during the whole read operation. R/W signal goes to HIGH state.

• Controller writes Address and Subaddress (address sequence).

Slave devices sample the data bus on the rising edge of the clock.

• Controller generates read clock cycles. Slave device puts data bytes at the rising edge of the clock. Controller samples the bus after every HIGH to LOW transitions on the clock.

• Transfer Enable (TE) and R/W signals return to LOW and a clock cycle is generated. Slave device frees the data bus after the LOW to

HIGH transition.

• Controller sends a PDIDATA answer to host computer.

4.8. Serial Data Interface

Version 2.00


The Gigabit Ethernet Controller has a two-way serial port

(Connector J), through which data can directly be loaded from IP to the device or from the device to IP. Several slave devices can be connected to the serial bus. Serial Data Interface (SDI) supports two operating modes:

• CW-Net compatible serial mode

• Normal serial mode

4.8.1.

CW-Net Compatible Serial Mode

In this mode operation is fully compatible with the CableWorld

CW-4900 Ethernet Controller’s Serial Data Interface. For details visit www.cableworld.eu. The pinout of the connector in this case is the following:

To load and read data through the SDI interface use the ENABLEON,

4.8.2. Normal Serial

Mode

Normal serial mode is very similar to PDI protocol. The differences are:

• There is no WAIT signal implemented.

• Data signal is not bi-directional. Serial Read (SR) is used to read data from slave devices and Serial Write (SW) is used to load data into slave devices. (The output stages of slave devices connected to

30



the SR wire must have an open-drain or open-collector to perform the wired-AND function.)

• The data bus (SR and SW signals) is serial MSB first.

• Controller sends a SDIDATA answer to host computer after read operation.

4.9. Selector

The Selector port (connector I) is a user programmable 9-bit output port. It represents a value between 0 and 511. Output pins (SELECTOR

8..0) can be programmed using SETSELECTOR instruction. The value of the port is stored in the controller’s EEPROM (see SAVESELECTOR instruction), so the last value will be loaded during power up. Each pin can be cleared or set individually with CLESRSELECTORBIT and

SETSELECTORBIT instructions.

4.11. IIC Interface

The Gigabit Ethernet Controller has an IIC (Inter Integrated Circuit

– I

2

C) interface (Connector L), through which data can directly be loaded from IP to an IIC compatible device or from an IIC compatible device to

IP. The IIC-bus has two wires, serial data (SDA) and serial clock (SCL).

Each device connected to the bus is recognized by a unique address and can operate as either a transmitter or receiver, depending on the function of the device. The controller is the master on the bus (slave mode isn’t supported). It implements the master functions of the 7-bit addressing mode. The master initiates a data transfer on the bus and generates all of the serial clock pulses and the Start and Stop conditions. At that time, any device addressed is considered a slave. For details about IIC interface and operation see the Philips IIC-bus specification version 2.1.

IIC supports sequences using READIIC and WRITEIIC instructions

(figure 15.). In case of read user can set whether the controller generates acknowledge after the last data byte or not (ACK bit).

Detailed ACK answer contains an IIC Error byte (byte 365). IIC

Error is cleared automatically before every IIC data transfer. Bit 0 (ADA) is set if acknowledge isn’t received after address byte. Bit 1 (WRA) is set if acknowledge isn’t received after every data bytes (in case of write).

Figure 15. IIC Error Byte

IIC clock frequency can be set for 100 kHz, 400 kHz or 1 MHz IIC operation using SETIICCLOCK instruction.

User could reset default settings by shorting Reset Defaults jumper

(connector T). It is useful when device is locked and user forgot the key, or the device’s IP address is unknown. To reset default settings follow these steps:

• Switch off (to power off state) the device.

• Short the Reset Defaults jumper.

• Switch on the device and wait for 5 seconds (or more). The power on LED is blinking.

• Switch off the device again.

• Open the jumper.
