" _" i8 P6 }8 o5 U9 a1 I) B9) HCI interface to the host CPU to enable flexible application development at the host level.
10) Transmission of IR control signals to the video source devices from the TV location.
2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
5 x% d2 x6 M" P6 z& AParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
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
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
9 O3 m7 W( x' o2 W, K. `% E4 hMbps.
4 j) P( H# ?" G7 J$ o' Z! n3 System Security
$ S; e: P! u) c' o4 q# bThe communication is authenticated and the media stream is encrypted to assure for
protection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
