5 C# D: Y8 ~, x& F9 D# @# j; a6 r0 t# E8 F5 r9) HCI interface to the host CPU to enable flexible application development at the host level.
' F* c/ a& v$ F) Z% _( ? 10) Transmission of IR control signals to the video source devices from the TV location.
& V' {. u* Y0 d, o( r 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
& q' N) @; N2 w8 N Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
% H% b: t j" Q8 UWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ T7 i4 {5 V8 L: S- E- X, ~' F% G 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
- W+ a! N6 E, c. f 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
