$ V- e) Z" v3 W/ P( d8 c 8) Configurable expansion I/O connector enabling easy integration with existing host
. g2 d. [! `! f5 ?4 d1 p systems.
' H7 o% a8 J9 h: ?9) HCI interface to the host CPU to enable flexible application development at the host level.
. w: s3 W" g# w+ x6 e0 k 10) Transmission of IR control signals to the video source devices from the TV location.
1 W( h# Z% b% Q# C5 L3 X# W8 F 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
! f! e1 B* d1 x3 j# Y Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
4 ]1 g J0 i) w WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
' p/ C) w6 a' k3 E4 B3 T: c 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
% h6 _, P! ?7 w3 b; p Z1 Vpower 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
