' Q. |+ G" S+ N7 V2 B- n5 _! D4 ` 9) HCI interface to the host CPU to enable flexible application development at the host level.
! o3 Z2 q# G7 U10) Transmission of IR control signals to the video source devices from the TV location.
/ @+ g7 X: n7 ]5 y 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
% g( I8 b7 j9 m5 w- SParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
# Z- _4 n: Z# S# V( d8 s WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ D% ]' o8 p% a8 t2 w2 O) }1 g different 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
& M6 d% g! T/ p! o3 j V2 Mpower 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
