- ^/ O1 {0 R3 W& k9 `$ J8 `10) Transmission of IR control signals to the video source devices from the TV location.
$ c/ F5 |0 I, w! f z2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
; A- U5 o$ n# E7 z
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
- r; F$ i8 S3 c$ O
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
* t7 i5 M; u' |; U2 [* M
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
8 T7 D+ }6 b, T3 F" ^) Y
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
