; [7 j1 \9 g; {) `6 V) b1 n+ H, t 5) Secure networking to assure privacy and content rights protection.
/ g( n* h. Q5 C& ?5 I 6) Supports most of the digital video formats at TS layer including MPEG-2, MPEG-4,
& A6 M! I6 a2 l8 ?( hH.264 and VC-1 (WM-9).
$ D5 l( ^0 p4 F! m1 c, `. B% f 7) Supports point-to-point video connection with full QoS and point-to-multipoint video
$ @' P0 ?9 t- r! Cbroadcasting.
! w8 D3 D3 @" s4 J* ?8) Configurable expansion I/O connector enabling easy integration with existing host
4 W: x7 n3 ]( E" Csystems.
! f% j( |& P# m p( K e% B9) HCI interface to the host CPU to enable flexible application development at the host level.
' c- ~5 t( v6 \9 D; E+ a6 Z q" H" X 10) Transmission of IR control signals to the video source devices from the TV location.
" v" T4 K0 ?, c2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
5 q) x8 S0 c. G+ r; C# j Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
6 _, V6 i8 y; B/ @" W: E4 e% w6 @ WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
; A8 l+ S1 b0 Q8 d5 u: m* n 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
! n1 n7 U- n/ F$ Mpower 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
/ Q3 X, x+ y. x0 W Mbps.
