; i$ n9 Z* l) d9 x4 S1 S3 v9) HCI interface to the host CPU to enable flexible application development at the host level.
" ^' t0 s9 k. v: B+ C10) Transmission of IR control signals to the video source devices from the TV location.
/ G% O9 P5 p/ ?. U* v2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
1 o0 M8 j* A! K1 M2 P+ V( BParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
