2 `; ^% W# ?! `6 f8 K; x8 f5 f9) HCI interface to the host CPU to enable flexible application development at the host level.
! O# J; a" Z1 K5 G10) Transmission of IR control signals to the video source devices from the TV location.
( `" J: _$ n3 u$ G" V$ ?0 d6 N; o2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
8 S: Y. V" F, T/ r, R$ tParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
" {& c8 M' K& G. O WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
0 W, V" F7 W" ~. A7 y2 pdifferent 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
6 F& c) z9 p0 i& t% q 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
