, C/ B' T d" A 9) HCI interface to the host CPU to enable flexible application development at the host level.
# A3 ?/ z2 G; ^" t# q 10) Transmission of IR control signals to the video source devices from the TV location.
P) U8 \# b, h8 v2 ^6 D. B2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
$ b6 y4 T. [' T! o5 b$ t, w Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ S f+ D0 J* _; t4 SWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
8 ^2 A& P1 [, u! gdifferent 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
1 C$ U! p& \7 Z3 q9 G7 ypower 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
