! q" O, l7 Y, j* a9) HCI interface to the host CPU to enable flexible application development at the host level.
" g2 r/ l g, m9 z* N4 c10) Transmission of IR control signals to the video source devices from the TV location.
8 _6 p- }+ ^8 R& N2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
7 [; y- Y4 i2 i' Y) t" G Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
0 A9 g# [' k( d# G+ GWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
' b* Z6 X% ^4 R3 N, r; `/ Qdifferent 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
( w% \: \: @. \5 [& Gpower 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
