$ C( N) n: T8 j/ j3 }- p( x 8) Configurable expansion I/O connector enabling easy integration with existing host
8 v. h, g2 b$ L# J( Wsystems.
4 _" }1 l0 b& x& `" D$ r; l- ^9) HCI interface to the host CPU to enable flexible application development at the host level.
3 i' `8 Y+ C' j9 }5 A10) Transmission of IR control signals to the video source devices from the TV location.
6 e/ K: d! V( M- B" ^) e2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
; G! m5 v5 J5 x Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
% w* P: Q' E! G, b WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
; a' G, ^% h+ o' i! `; U% W2 l7 O 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
' n. F: i: A1 P6 `# {* I& I 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
