Which audio and video codecs are in use on the Access Grid?
In the Access Grid, a codec (COder-DECoder) deals with the transformation of data signals, enabling users to see and hear others at different sites. Codecs are contained within the audio and video tools used by open source and IOCOM Access Grid clients. There are specific codecs in use for both audio and video and these must be compatible at different sites for everyone to be able to see and hear everyone else. Currently, the only video codec that is compatible with both IOCOM and AGToolkit is H.261. However, the IG2 IOCOM software is capable of using H.264, which offers higher quality video at an equivalent data transfer rate, but uses more processing power. The open source Access Grid toolkit video client, VIC, is currently only capable of using H.261; this means that in a session with both IG2 and AGToolkit clients, IG2 users must use H.261 to enable VIC clients to see all video streams. (Note: the SUMOVER project at UCL is working to develop VIC to use H.264.) If you are using AGTo

Codecs are contained within the audio and video tools used by open source and inSORS Access Grid clients.

Currently, the only video codec that is compatible with both inSORS and AGToolkit is H.261. However, the IG2 inSORS software is capable of using H.264, which offers higher quality video at an equivalent data transfer rate, but uses more processing power.
