/ m# m9 J" m+ a/ R/ L, z9) HCI interface to the host CPU to enable flexible application development at the host level.
8 `7 I8 T& Z1 q* G' O7 E" g- J10) Transmission of IR control signals to the video source devices from the TV location.
1 h9 k! I* v w" \2 [ 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
! N9 N! y: w1 TParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ [- ~ F' a( v9 ^( W* o* [" zWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
/ c+ x! [2 N2 f8 d+ Y6 Kdifferent 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
" K$ A+ m0 s6 O. |" F; Rpower 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
