4 w B$ ]& ^- {% U 9) HCI interface to the host CPU to enable flexible application development at the host level.
/ u; W; u- c" {5 G; _1 p3 f0 M8 ~10) Transmission of IR control signals to the video source devices from the TV location.
' ~5 L- \# B1 N. ^ 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
7 N2 Z8 x4 t/ u# y$ x( c) Z7 U Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
7 V6 |* I+ m7 C) z* U s) R WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ e* ]$ c: v; U7 {8 S3 f 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
# b# C T# r9 @! x/ e* 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
