IP address

After enabling the 3G network, you can initiate an H.323 or SIP video conference using the terminal over the 3G network.

This specifies the mode for obtaining an IP address. The default value is

Dynamic. It is recommended that you use the default value.



Dynamic: The terminal obtains an IP address dynamically and automatically from the network.



Static: The terminal uses an assigned IP address to connect to a specific server.



If IP address type is set to Dynamic, the IP address assigned by the server is displayed in this text box only after a Point to Point Protocol

(PPP) connection is established successfully. After being registered with the GK using the assigned IP address, the terminal can call remote sites using the relevant numbers, names, or IP addresses over the 3G network.



If IP address type is set to Static, you can enter the IP address manually.

Authenticatio n mode

When the terminal is connected to a 3G network in PPP dial-up mode, the authentication mode can be set to PAP or CHAP to prevent the access by unauthorized users. The default value is CHAP. It is recommended that you use the default value.



If you set the authentication mode to password authentication protocol

(PAP), the user name and the password are transmitted over the network using plaintext. If the user name and the password are captured during transmission, the network security is at great risk. Therefore, you can use the PAP mode when the network security requirement is comparatively lower.



If you set the authentication mode to the Challenge-Handshake

Authentication Protocol (CHAP), only the user name is transmitted over the network. Therefore, this authentication mode provides a higher security level than the PAP mode. In CHAP authentication mode, each inquiry message for authentication is unpredictable and unique, preventing recurring network attacks.

6.4 Setting Up an H.239 Dual-Stream Conference

During an H.239 dual-stream conference, two independent video stream channels, that is, the video and the presentation, can be transmitted; furthermore, two channels of video from the local site can be transmitted or two channels of video from a remote site can be received at the same time.

If the license on the terminal does not support H.239, the terminal can receive presentation, but cannot share presentation.

6.4.1 Designating the Dual Streams

Input sources and output destinations for the video and presentation must be chosen.

Choosing Input Sources

If multiple video-source devices are connected to the video input interfaces of the terminal, you can choose a channel of video as the source of the local video and another channel as the source of the local presentation.

The priority of the video is higher than that of the presentation, as shown from the following aspects:





After a conference is initiated, the remote sites view the video of the local site before the presentation.

During the layout switch in continuous presence mode, the remote sites can always view the video of the local site.

Choosing Output Destinations

During an H.239 dual-stream conference, if local video and presentation and remote video and presentation exist simultaneously and if multiple monitors are used at the local site, you can set the output interfaces for the videos and presentations as required.

6.4.2 Enabling the H.239 Mode

After enabling the H.239 mode, the video and the presentation can be sent simultaneously during a conference.

Problem

The local video is not displayed properly. For example, the video is in black and white or blinks in black and white.

After the local site joins a conference, the video of a remote site is not clear. For example, there is mosaic, frozen image, or discontinuity in the video output.

Possible Cause

The current video output interface is set to display the local video.

The output mode of the video output interface is set incorrectly.

After you perform a local video loopback test, the video quality is poor, which indicates that faults exist on the local video module.

When the scene captured by a remote camera is changed, the remote video is not clear because the remote camera is not set to focus automatically.

In this case, the remote camera is set to focus on a near or far scene.

When the conference rate is lower than 256 kbit/s, the audio protocol is set incorrectly. For example, access the Call Statistics screen. If the conference rate is 256 kbit/s and if the audio bandwidth is 64 kbit/s, the video bandwidth will be only

196 kbit/s. Therefore, the video quality is poor.

Low video bandwidth is available for the local site because the network is busy.

Certain data is lost during transmission, because the quality of a network connection device (such as an optical fiber transceiver) is poor.


Solution

Set the current video output interface to display the remote video.

It was first proposed in the H.261 standard. continuous presence A feature in multi-point conferencing that allows the video endpoint to see images from multiple video endpoints at the same time. All parties remain continuously visible or 'present' for the duration of the call and the user can have control over the screen layout. Continuous presence is better suited for team collaboration since it allows participants to see the reactions (body language) of all participants, not just the speaker.

Users see two sites on one monitor in two panes. The two panes are of the same size.

Each pane is about 1/4 of the screen. Use 2-pane as an adjective.

G.711

G.722

G.711, also known as Pulse Code Modulation (PCM), is a very commonly used waveform codec. G.711 uses a sampling rate of 8,000 samples per second, with the tolerance on that rate 50 parts per million (ppm). Non-uniform quantization

(logarithmic) with 8 bits is used to represent each sample, resulting in a 64 kbit/s bit rate. There are two slightly different versions; μ-law, which is used primarily in

North America, and A-law, which is in use in most other countries outside North

America.

G.722 is a ITU-T standard 7 kHz wideband speech codec operating at 48, 56 and 64 kbit/s. It was approved by ITU-T in November 1988. Technology of the codec is based on sub-band ADPCM (SB-ADPCM).

G.728 is an ITU-T standard for speech coding operating at 16 kbit/s. It is officially described as Coding of speech at 16 kbit/s using low-delay code excited linear prediction.

After the chair site gives floor to a site, the other sites view and hear the site. All the sites, except the chair site and the site that is given the floor, are muted.

H.239 is an ITU-T recommendation from the H.32x Multimedia Communications' macrofamily of standards for multimedia communications over various networks.

The H.239 recommendation is titled "Role management and additional media channels for H.3xx-series terminals". Practical importance of this recommendation is its setting forth a way to have multiple video channels (for example, one for conferencing, another for presentation) within a single session (call).

H.261 is a 1990 ITU-T video coding standard originally designed for transmission over ISDN lines on which data rates are multiples of 64 kbit/s. It is one member of the H.26x family of video coding standards in the domain of the ITU-T Video

Coding Experts Group (VCEG). The coding algorithm was designed to be able to operate at video bit rates between 40 kbit/s and 2 Mbit/s. The standard supports two video frame sizes: CIF (352x288 luma with 176x144 chroma) and QCIF (176x144 with 88x72 chroma) using a 4:2:0 sampling scheme. It also has a backward-compatible trick for sending still picture graphics with 704x576 luma resolution and 352x288 chroma resolution (which was added in a later revision in

1993).

H.263 is a video codec standard originally designed as a low-bitrate compressed format for videoconferencing. It was developed by the ITU-T Video Coding Experts

Group (VCEG) in a project ending in 1995/1996 as one member of the H.26x family of video coding standards in the domain of the ITU-T. H.263v2 (H.263+) added support for flexible customized picture formats and custom picture clock frequencies.

Previously the only picture formats supported in H.263 had been Sub-QCIF, QCIF,

CIF, 4CIF, and 16CIF, and the only picture clock frequency had been 30000/1001
