" C1 B' x" ?: |4 a 9) HCI interface to the host CPU to enable flexible application development at the host level.
/ B, M- i8 f, P0 u10) Transmission of IR control signals to the video source devices from the TV location.
, a; G' L" t/ d' m* G 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
0 ]4 D: @, E/ S' J+ t/ C Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
6 [9 Q* z& z( u) q6 { WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
8 Z1 b [- z, mdifferent 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
# a3 y" x- [. ^2 Y" j: h 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
