# V0 {# r% u3 h/ U7 B) ] z 9) HCI interface to the host CPU to enable flexible application development at the host level.
, w9 a$ C2 d5 I+ Q$ X7 l- m6 p10) Transmission of IR control signals to the video source devices from the TV location.
( K2 x9 d. D3 {+ k* A8 w 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
( a9 d; k7 B- p3 X; u, H Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
0 r. E: {* ?/ l: J. ]WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ c9 N0 e1 u- [& d7 G7 |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
8 G$ s' q5 ^, h- D5 h$ S# A' S/ 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
