! j4 V+ _* j6 Q9) HCI interface to the host CPU to enable flexible application development at the host level.
# S' ?) j+ O0 O4 {. {( {" h 10) Transmission of IR control signals to the video source devices from the TV location.
+ V( g9 d: u W2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
7 ^6 [' |5 {- L9 q9 c: ]; I7 [% oParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
- Z1 e4 D/ v+ ~WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ R, U0 J/ F* Ldifferent 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
6 [& F4 ?( }8 i power 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
