3 w/ G% h+ {2 h 9) HCI interface to the host CPU to enable flexible application development at the host level.
6 l: x0 w) B3 o1 Z( C6 l( m2 B( X 10) Transmission of IR control signals to the video source devices from the TV location.
# Y+ Y4 j% N; V: `2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
3 r; `( R9 C1 u; T8 c, i, x Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
/ W& H- I" L0 b2 [) ^1 l WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
7 b/ d5 L/ m; Z: r a0 @! I6 Y 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
, I! B/ G1 z) n2 H. D; A8 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
