( C1 ^. p/ ?8 G& w6 L1 F4 o, Y 9) HCI interface to the host CPU to enable flexible application development at the host level.
x% Z" a+ K* e1 A2 q' y# U" H: c 10) Transmission of IR control signals to the video source devices from the TV location.
2 {- |: L4 r1 X( `+ S( j 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
6 I$ @) f- w6 o Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
& }( Q8 A! A+ W) A" j. Q& Y 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 U; w5 F3 Y1 {' e+ S% @3 c. Kdifferent 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, I. [3 @/ `1 r H 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
