' v0 C% r! H" l2 M 9) HCI interface to the host CPU to enable flexible application development at the host level.
5 M2 l& o/ {4 f0 ~ 10) Transmission of IR control signals to the video source devices from the TV location.
; @: G/ @6 k5 u5 O: [ 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
5 K1 \: W- V# y' V Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
; l5 \ y$ Q/ H& [, T) lWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
) O4 r7 n7 l; E; c8 ~( X) R 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
$ ^3 `) f4 S' d3 I 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
