+ r$ b8 \. q1 Q# W/ O6 c3 ?: M. q/ S 9) HCI interface to the host CPU to enable flexible application development at the host level.
# _! s3 N, |* d3 B1 \- ~ 10) Transmission of IR control signals to the video source devices from the TV location.
6 X" T, p, S5 B4 d2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
! f2 {2 ]# ~" C& e! f# l5 EParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
# @- @6 J. o# a& o+ i- [% [# z WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
& i z c K" c5 gdifferent 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
0 X6 k3 _. Q/ s 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
