# e" |& T% Q) L* z& y+ \6 B10) Transmission of IR control signals to the video source devices from the TV location.
3 s4 M' p& o) ]. v& f# R6 w ^ 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
$ N5 O! b) n& l0 ]/ E Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
2 x+ }. w# O" G+ b3 L7 U 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 B& q4 F8 t$ K1 D" _1 Z' C }) ^ 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
; @ b( X! c c4 u' { ?' r- } 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
