. ?! A$ \3 i' f# V systems.
& U5 u- S9 k3 G; a2 W; {9) HCI interface to the host CPU to enable flexible application development at the host level.
! Y1 D0 `9 x' F C10) Transmission of IR control signals to the video source devices from the TV location.
2 h4 b% p& d7 b2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
, V& g6 |- }* g% u8 u2 c Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ D& ~7 r8 H; K1 `3 BWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
4 B; s& C, T9 l# Pdifferent 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* h# d) S* ^ c; B, q& ]- Cpower 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
