1 Z: p$ E! m. g& R9) HCI interface to the host CPU to enable flexible application development at the host level.
8 r- q& ^1 w# V* Q: F+ F 10) Transmission of IR control signals to the video source devices from the TV location.
! b" e0 u1 B S+ f 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
. f5 f1 r" x/ D Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
0 k4 P1 R, l/ l8 EWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
! {( w; U1 P% `1 a* Y T+ \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
