9 u6 B& m! l9 D/ K systems.
& n$ e+ }, Y) x& X* P6 o9) HCI interface to the host CPU to enable flexible application development at the host level.
8 b9 J5 ?8 A8 g1 U% ~ 10) Transmission of IR control signals to the video source devices from the TV location.
" M7 i; h' q; V: ^! n3 V8 S: ~ 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
A4 j- N% K2 j. I% b+ Z: K Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
6 Z9 I4 u3 `" \; N6 r6 N! u$ f WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
( I9 @' {! p9 K* t' E# I" cdifferent 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
4 a/ G" r" }4 j 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
