6 J' V, ~, v# [$ B. }/ K( F9 [ 9) HCI interface to the host CPU to enable flexible application development at the host level.
# b/ ^' j, t1 h" q' n8 T10) Transmission of IR control signals to the video source devices from the TV location.
8 o: m( H5 k2 C. t$ j. y2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
2 m0 N$ \! W, G, R, L! vParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
% q" `- L( s d WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
& C& A. ?# R. z* D" P$ Sdifferent 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
* F! O4 N" E1 m9 ~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
