What is the data rate produced by the audio and video applications?

0

The audio coding provided by the built-in audio hardware on most systems produces 64 Kb/s PCM audio, which consumes 68-78 Kb/s on the network with packet overhead. The audio applications implement software compression for reduced data rates (36 Kb/s ADPCM, 17 Kb/s GSM, and 9 Kb/s LPC including overhead). For the slow-frame-rate video prevalent on the MBONE, the compression, decompression and display are all done in software. The data rate is typically 25-128 Kb/s, with the maximum established by a bandwidth limit slider. Higher data rates may be used with a small TTL to keep the traffic within the local area. Support for hardware compression boards is in development.
