8 x- P2 g, U: ?9 O2 E* {10) Transmission of IR control signals to the video source devices from the TV location.
& [( X+ Q4 F& p5 D! U2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
2 c8 n; L n- c& q2 z- F Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ \% B U+ U1 n# }9 RWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
4 y8 I4 W; `( G& g! `" _# Qdifferent 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
' _- U; J( V& a% P% N) 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
