' E; R( h! m! ]5 N9 ~ F% l3 q9 H5) Secure networking to assure privacy and content rights protection.
6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
6 H6 `1 X( m ?/ @7 {* gH.264 and VC-1 (WM-9).
7) Supports point-to-point video connection with full QoS and point-to-multipoint video
broadcasting.

4 `& U X2 U& K0 H10) Transmission of IR control signals to the video source devices from the TV location.
2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
( S8 M6 u4 Z" [+ V1 `Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
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
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
) g b; I2 B, qMbps.
3 System Security
4 P6 m/ e" }3 U5 i4 u# HThe communication is authenticated and the media stream is encrypted to assure for
protection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
9 j' X1 @% ?% J! h4 i, [$ ?) @: aensures private communications between each pair of units. This also allow for coexistence of
4 \" E0 A3 W/ Imultiple pairs of simultaneous operations without cross talk.
