" x3 f p( S/ R1 _( A9) HCI interface to the host CPU to enable flexible application development at the host level.
$ n9 m; X! a) a& c 10) Transmission of IR control signals to the video source devices from the TV location.
# l. B; N$ S1 c2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
4 s) l7 T; @2 c, bParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
