1 h* K0 I, P; \# L9) HCI interface to the host CPU to enable flexible application development at the host level.
5 ~8 ?: @/ R/ I4 F: h7 Z10) Transmission of IR control signals to the video source devices from the TV location.
3 k% M8 W2 A: p2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
% f, @9 I+ B& t8 B( S, b4 _Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
3 Q9 B$ F7 G. |8 Q# x4 I WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
7 z' }! X5 w% M! x- w. k9 Y- wdifferent country spectrum requirements.
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
% E1 z( a6 J4 J6 ipower control (CLPC).
Overall video propagation delay of less than 30 ms.
Receive sensitivity is –86 dBm for video rate of 6 Mbps, and –78 dBm for video rate of 20
