5 ?3 n' v, K" H" w9 Ysystems.
- o2 \- G8 c, G, Z9) HCI interface to the host CPU to enable flexible application development at the host level.
6 N! M8 |: H, r$ |. b" t! s1 N& y10) Transmission of IR control signals to the video source devices from the TV location.
$ J4 G$ M" {" Y6 P' D$ ^2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
& C; w0 ~( |) f: g) Z2 i# dParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
. g; y, I y9 L/ z' i WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
o! N/ r4 w2 V0 V 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 w4 H* E: [/ z" |- upower 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
