The AL9M803 chip provides proprietary data flow control infrastructure for a smooth streaming of multimedia contents. They stream video plus audio from source devices, such as STB, DVD player, and contents from DTV tuner to the video receiving devices, such as TV monitors. They can also stream audio from a home-theater system to its surround speakers, and music from i-Pod charging dock to speakers at different rooms, etc.
