& r4 i% F$ G( X. Y9 t5 V5 B: R9) HCI interface to the host CPU to enable flexible application development at the host level.
" y. Q8 ~9 U3 C |- }$ O) Z10) Transmission of IR control signals to the video source devices from the TV location.
6 w/ H/ ~# F3 v7 S- e2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
' i# g/ ]/ H8 i& ~Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
1 `0 N9 e# N$ P, N4 @, g% uWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
( J9 D' v5 X) s: ]. x5 ^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
. D# t& w0 P, O! k0 }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
