7 i; |. H+ f6 v: a1 M 9) HCI interface to the host CPU to enable flexible application development at the host level.
/ U: b; J# S$ |9 x: R$ R10) Transmission of IR control signals to the video source devices from the TV location.
! |; S H$ q& e& _3 [ 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
0 U- t. K- f! e2 r; {8 d Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
. F8 F" W! K. s: b WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
% \- M+ l8 O' T# U! M# L- X2 l 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
8 y l7 \7 W) q* c( C& D 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
