. a3 h* g# L" e# K9) HCI interface to the host CPU to enable flexible application development at the host level.
5 @2 @; D9 O+ l' B) B% Z" S! M10) Transmission of IR control signals to the video source devices from the TV location.
+ i& K: [+ L0 ?+ V% y 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
- @- b! t& b7 Z/ KParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
+ Y; A: t+ @$ z. \1 D WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
2 l+ x4 d, K& ~6 Z; X+ X( c% E 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
" s$ Y! J7 ^3 D, N0 Q0 p- Fpower 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
