2 i3 {/ Q' d3 o: B/ J9) HCI interface to the host CPU to enable flexible application development at the host level.
0 f8 v* o6 ^1 k1 d 10) Transmission of IR control signals to the video source devices from the TV location.
. v, h% O" N% Y/ L9 k' p2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
# T' [ E9 O& i. Q Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the

The system support data rates from 6 Mbps to 60 Mbps.
The system supports video bit rates from 3 Mbps to 45 Mbps.
Proprietary radio resource control with dynamic frequency selection (DFS) and close-loop
