, m& g! h- f" b, J 8) Configurable expansion I/O connector enabling easy integration with existing host
% [8 X( s5 j1 ]" D* k; z1 s; v R. }systems.
$ }( ?9 c; u9 f3 x% H$ X9) HCI interface to the host CPU to enable flexible application development at the host level.
8 D' g+ D8 \- V; q( O w 10) Transmission of IR control signals to the video source devices from the TV location.
& A% v0 |7 V; U4 N" x9 H 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
: P" @. W, Q& \; z Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
8 K9 A& H* `' b3 p0 a WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
1 s# [) D& |( m; _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
( v/ M9 r2 Z) U+ C( 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
" Y' d. h3 a( f Mbps.
