0 j( W) y( S; u# _9) HCI interface to the host CPU to enable flexible application development at the host level.
# n3 f0 g; }8 L. S10) Transmission of IR control signals to the video source devices from the TV location.
2 J% M8 A* r( x0 ]# g 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
: x% g* H4 \* o5 m- J1 i Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
* h/ G0 R' z0 V6 \$ z" y: S WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
! P. v# o" _$ H: {2 t2 Z 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
- ]& E4 a3 x/ U4 w0 b 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
5 {6 t5 S6 x2 }Mbps.
