# F' i$ t5 x3 m* t9) HCI interface to the host CPU to enable flexible application development at the host level.
, |. n$ C9 s, w8 D4 h6 b 10) Transmission of IR control signals to the video source devices from the TV location.
7 T7 P2 z. h7 [ 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
; N( o1 Z) O L* e Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
( @$ c' N3 _4 V. EWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
$ E. e* c# I& ]; @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
" u, m5 M3 t& P/ j# Q* wpower 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
