4 z# |( H/ T( a- u- N- i0 z 8) Configurable expansion I/O connector enabling easy integration with existing host
0 z c- j5 t5 b1 }) k0 Q7 Z systems.
- h! M4 R! B# |6 e 9) HCI interface to the host CPU to enable flexible application development at the host level.
% U3 m" _' _- j. f 10) Transmission of IR control signals to the video source devices from the TV location.
2 z1 g2 l4 ] j4 B6 t$ |2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
3 x2 m3 K/ B6 h( z/ OParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ U1 z' T( r4 {! R& L CWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
! {% m% _* i' z5 W; N& ]! t2 X7 [ 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
2 v: C3 x* ~0 z$ f" W* Z 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
