5) Secure networking to assure privacy and content rights protection.
' _/ \3 p$ V: C- a& d) c6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
# [* E4 ^: s! a$ BH.264 and VC-1 (WM-9).
* d. y: Y7 ^& a6 g4 I9 d7) Supports point-to-point video connection with full QoS and point-to-multipoint video
broadcasting.
8) Configurable expansion I/O connector enabling easy integration with existing host
systems.
9) HCI interface to the host CPU to enable flexible application development at the host level.
10) Transmission of IR control signals to the video source devices from the TV location.
. x: ]5 l, d7 u' H& F% T) a2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
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
3 R" E" ^9 I2 S: 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
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
% ]8 I- @$ H6 B2 yMbps.
; t) I' `, w' S3 System Security
The communication is authenticated and the media stream is encrypted to assure for
4 t7 N( Q6 g* ~7 t6 Dprotection of copyrighted material. Flexible pairing procedure between each Tx Unit and Rx Unit
* P# _/ X7 G0 S5 V0 t7 D4 h$ {/ ?2 jensures private communications between each pair of units. This also allow for coexistence of
8 p( W! X7 Y4 f6 S# zmultiple pairs of simultaneous operations without cross talk.
