4 X& r8 F7 {" g1 g% H 8) Configurable expansion I/O connector enabling easy integration with existing host
( ?/ T9 w. X4 D2 ?7 L7 _systems.
# U( ^2 V' K ` 9) HCI interface to the host CPU to enable flexible application development at the host level.
" z2 j2 m. P8 y) S i+ L 10) Transmission of IR control signals to the video source devices from the TV location.
; ~& V& v1 E8 {+ C 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
& ]1 b M' m9 U* ^& _Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
1 N8 X8 V/ t7 z+ d% \9 j1 }WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
$ a, Z7 x1 _9 M: N2 g( w0 ^ 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
# g: T* i! E/ Q 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
