Building a AVB node the stream reservation protocol and the precision time protocol are to be built in the linux kernel. A demo application will be included for a stereo speaker system with two individual beagle boards. The first board will decode a stereo audio file (ex: mp3 files stored in local disk) and play one channel of the audio through its speakers (ex: left channel) and then it transmits the second channel (ex: right channel) to the second device over AVB which plays back the second channel through its speakers. The objective is to achieve frame synchronization over such a system. This can be tested by recording the output from both devices and analyzing with an audio analyzer. In this case one device acts as a AVB master node and the second device acts as a AVB slave node.
