" y! e) H/ z* jsystems.
5 ~1 N8 b, [( a" C8 `" k- `9) HCI interface to the host CPU to enable flexible application development at the host level.
/ n% t: }* {/ r E' e1 L10) Transmission of IR control signals to the video source devices from the TV location.
1 U5 t l' |3 R" p) x 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
8 ?4 D0 r- z9 yParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
3 W; V& r) a- W4 }* y. GWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
$ n( l- ~5 E; l# K 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/ T4 t" v# b/ z3 ^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
