2 H/ V! B- p# e9 | {1 e1 v- i A 10) Transmission of IR control signals to the video source devices from the TV location.
2 F ?) A+ X) ]8 S# Y2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
$ Q B9 N; k' Y# @4 F Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
- O' O0 z5 C/ q4 i! {( C WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
8 |+ p$ G q+ O* v8 C0 Q/ Y7 pdifferent 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
0 _9 K9 H' H. n. p 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
