- \2 c& W9 C0 G6 r$ i. f& U/ M- A( e 8) Configurable expansion I/O connector enabling easy integration with existing host
( I* E1 G) ? k; w% W: B2 jsystems.
: k7 G) l; p: A6 Q7 u' i 9) HCI interface to the host CPU to enable flexible application development at the host level.
2 Q9 q- r% e% H5 W4 i1 k- k1 w' Q% o 10) Transmission of IR control signals to the video source devices from the TV location.
- e1 e( P* f' E* D 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
+ L$ `2 T4 k G' R Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
# N: I5 n% ]2 a( WWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
" j' q' z( G3 ~5 @ 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 O7 N! [) o# k, B6 Y9 U 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
