3 P2 `7 N; H8 Y! f; [9) HCI interface to the host CPU to enable flexible application development at the host level.
& n' Q9 w% }3 {7 x! Y$ v6 J10) Transmission of IR control signals to the video source devices from the TV location.
7 r1 T3 s+ H' P9 }0 g+ m2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
8 j( a( S: r. w1 w/ \/ nParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
( @# y }1 v. h6 G- B% z WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
- f0 J! H( D, \# [" edifferent 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
1 E5 S7 ?/ z' g8 Tpower 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
