8 \# b0 T: a9 G' s; `7) Supports point-to-point video connection with full QoS and point-to-multipoint video
7 i6 L: G; p* C0 ebroadcasting.
0 K4 r/ x5 ~7 E$ o5 V- n( [/ ]. M* O8) Configurable expansion I/O connector enabling easy integration with existing host
% C5 L* l! Q* hsystems.
- C8 P2 l+ D: d& l. ?4 r. K3 c9) HCI interface to the host CPU to enable flexible application development at the host level.
3 l& x5 k& E) \! h# Z" m9 Q 10) Transmission of IR control signals to the video source devices from the TV location.
8 X( x" M' G K2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
( E) a, M9 g( o w h+ C! O Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
. B+ `2 |( L* }8 m5 k$ I/ y WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
* ]9 W% |0 Q6 e' b. M# v! V% 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
4 l2 X% R1 ?7 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
