: ]5 k8 A7 z- [% a7 p5 p2 J9) HCI interface to the host CPU to enable flexible application development at the host level.
- l* T" K3 _* s' e' H5 d/ e 10) Transmission of IR control signals to the video source devices from the TV location.
' U$ p! d, [- ?$ g, q$ x' N 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
2 \( a. D1 M$ w( I* KParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
