2 v( g' W) i/ O9 G& m4 R7 w9 y. ~8) Configurable expansion I/O connector enabling easy integration with existing host
$ {- E! Z' {$ q6 Ksystems.
0 A/ _) D+ q$ T6 ` t' S; ]3 d1 c2 I9) HCI interface to the host CPU to enable flexible application development at the host level.
" p- ?* f0 f* l# D z8 g9 T$ `" n8 Z+ A 10) Transmission of IR control signals to the video source devices from the TV location.
( z+ \9 C/ @& n8 ~: X 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
; H: i" ]( k/ |' S# e8 K Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
! Y4 v8 Q) j$ r4 _WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ y' T9 ]# e/ }0 p3 x 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
' y' B W$ i, g' upower 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
$ u) n8 }* `' G& rMbps.
! ^) ~, R; \+ a K+ c 3 System Security
% o# I1 |# U( D- c$ eThe communication is authenticated and the media stream is encrypted to assure for
