* F* v$ }$ z/ E" c3 B/ }9) HCI interface to the host CPU to enable flexible application development at the host level.
- r) b* u) x. d10) Transmission of IR control signals to the video source devices from the TV location.
8 w: m" l4 {) B+ P 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
9 [; h/ X+ P. P. H Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
V* v6 w% G1 O7 P( M7 K- y8 v2 jWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
: v6 r- c( c/ t5 p* Q 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
$ ]4 G/ C A0 \: j 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
