4 S2 ]: Q. L3 F, i+ l5 y 5) Secure networking to assure privacy and content rights protection.
' J# ?5 {$ }/ N' D5 u 6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
& e5 F' Z# @% X H.264 and VC-1 (WM-9).
$ u; z V( }* I. a- q& i. I. i+ I7) Supports point-to-point video connection with full QoS and point-to-multipoint video
( k2 F( x% l: z broadcasting.
% M7 |) Z: D. h2 M0 e z 8) Configurable expansion I/O connector enabling easy integration with existing host
" x2 k# _+ U, ]0 ysystems.
' ~! j4 Y5 d* f 9) HCI interface to the host CPU to enable flexible application development at the host level.
6 a1 H( M/ B/ R 10) Transmission of IR control signals to the video source devices from the TV location.
, N/ Z' S' ]( h0 S! O7 }0 ]# ]2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
4 s8 I% T! u' o, }: N9 a( @9 _Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ D) x; @. S4 @, ] WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
" H u8 y( M" Udifferent 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
, M/ n) R! P I( v# M' Fpower 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
