6 ]0 A; k3 w/ I* k/ ~' I 8) Configurable expansion I/O connector enabling easy integration with existing host
6 _" o I( y: {! d' v% d systems.
# Q4 Y4 X( p, ~' X 9) HCI interface to the host CPU to enable flexible application development at the host level.
! n, E) I$ b3 t10) Transmission of IR control signals to the video source devices from the TV location.
; @9 O [- U, k' Q3 V" O. s( z9 U2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
1 O$ m/ l4 Q6 v3 E1 Q+ p6 X Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ w# v0 O0 W- b, uWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
+ m, ^- f$ L9 R! r: F. d: X, 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
& o+ Y/ B2 i; Y0 npower 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
