7 S V3 F, W9 W$ q* A" F 7) Supports point-to-point video connection with full QoS and point-to-multipoint video
3 R" P `/ f, f" K& I0 n2 P' E broadcasting.
( T3 z$ L5 a& u9 M, B 8) Configurable expansion I/O connector enabling easy integration with existing host
& G! ?7 u9 L; T1 C systems.
9 M/ U' |* [- K 9) HCI interface to the host CPU to enable flexible application development at the host level.
l- E( p* u+ Z0 G7 z) A 10) Transmission of IR control signals to the video source devices from the TV location.
* J" {7 X7 M4 ]7 h+ p b, p+ v! J 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
% J' C- w' l2 D% C Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
/ h+ I; }* ]2 i) K, FWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
! E) D f/ I x0 V6 U! ^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
( h! q+ W" B5 A- q* ?3 Opower 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
& I8 W G& p5 E0 Z2 Y Mbps.
9 |9 I$ J1 [ _+ D$ ]8 t. v 3 System Security
7 Q( }* j% m i. P( yThe communication is authenticated and the media stream is encrypted to assure for
