0 T9 K% l9 r$ J! [% @! E10) Transmission of IR control signals to the video source devices from the TV location.
) I7 f/ p: Y3 @1 X6 c: h9 } S2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
- n1 G/ |$ L% \Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
a5 a/ C4 |; |1 P WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
7 R# M# H8 H' m U! T 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
; t, _( C( w2 i e- S 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
' t3 d2 `8 C6 ZMbps.
