1 GENERAL DESCRIPTION
A member of Alitronika’s state of art digital video interfacing products.
The AT40USB is a USB based interface device suitable for Recording, Playing and Analyzing of DVB-ASI
Transport Streams.
2 BLOCK DIAGRAM
FIG4 illustrates the block diagram of the AT40USB device. The device communicates with the PC via the
USB interface device. On the input side, the serial data is de-serialized 8b/10b and de-coded before it is
presented to PC via the USB controller device. On the output side, the MPEG-II transport streams enter the
device via the USB interface device. The AT40USB then transmits the transport streams according to the
settings provided by the application software. The data is 8b/10b encoded for DVB-ASI signals before it is
serialized and transmitted via the BNC output connectors.
3 EXTERNAL INTERFACES
The external interfaces for the AT40USB are shown.
There are two BNC connectors for the Serial input
and output of DVB-ASI.
The three LEDs in front of the unit function as follows:
PWR - Top LED
Power LED
CD - Middle LED
Play/ Record LED
ON = Power is on
OFF = Power is off
ON = Device is Playing/Recording TS
Flashing = Play /Record not activated
In Record mode this LED indicates that a Carrier has been detected.
In Play mode this LED indicates that the output section has valid TS.
LCK - Bottom LED
LOCK LED
ON = Device is locked to TS
Flashing = No lock has been achieved
In Record mode this LED indicates that the device has locked into incoming TS.
In Play mode this LED indicates that the output section has locked into outgoing TS.
4 APPLICATION
Targeted for digital video professionals, sophisticated end users and OEMs the AT40USB is an ideal
solution for a number of applications such as, development tools, universal interface for MPEG-II Transport
Stream Playing and recording, video on demand server, transport stream test generator, high speed serial
data link, software based MPEGII decoders & encoders and many other applications.
