5 Q4 n) |8 E. P" ]" B( V6 f8) Configurable expansion I/O connector enabling easy integration with existing host
7 z, V; h6 u6 _systems.
4 c0 g) H$ G& ]( m9) HCI interface to the host CPU to enable flexible application development at the host level.
0 b$ t3 Z* r" g" x 10) Transmission of IR control signals to the video source devices from the TV location.
+ O2 ]" B; m. v0 X7 \3 ~( H( ?- E7 m 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
! R& _0 p+ {8 t8 U Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
8 D7 u- Z* w$ b2 A9 lWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
* b3 n; I; \' G* ~; ^ 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
1 S: \- \# B6 V) w$ V3 K( e 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
