2 F5 ?) `% B. a8 X5 C! u10) Transmission of IR control signals to the video source devices from the TV location.
1 u6 h- O6 A1 ]9 y6 u4 H- j& ^2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
G& w" m% d4 a7 j+ HParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
/ A5 c5 \5 ^$ `5 `( hWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
9 [9 n) n, d+ t5 F. H$ `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
5 V0 |) m0 F0 }; Y T 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
