" @8 M/ m6 V, Q5 n 10) Transmission of IR control signals to the video source devices from the TV location.
' s; D& v% K& y 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
+ S" s" |- }! @- z5 lParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
2 {. C/ a: t' d: L; F WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
3 x" L6 f) x9 F6 ]. ]1 D$ zdifferent 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
$ J& F5 G3 u. A4 D. 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
