3 {$ B+ A. ~# V; H4 H8) Configurable expansion I/O connector enabling easy integration with existing host
1 J j2 u" K2 z+ V4 ~7 ~8 ksystems.
5 u: B5 t( n. X+ n# t6 @$ v9) HCI interface to the host CPU to enable flexible application development at the host level.
9 w6 M" e s8 M! Z: d9 G10) Transmission of IR control signals to the video source devices from the TV location.
4 \0 s' ^& e, w; k K, b 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
- G0 W6 T; _$ p% g4 h& S Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
" ?8 Z) Z4 ~) B; S WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
o% n! h% r& j 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
+ U* Q6 g* \6 H$ T( [; r* y 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
