: z3 o; B' K& S; J% V7 j10) Transmission of IR control signals to the video source devices from the TV location.
( @$ c3 f# W. x. p# \' J 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
: ~) i# P( t( u1 G7 ]' R Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
$ `7 Z# g+ [* C WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
* i, G+ C$ V% s3 H 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
! D/ h1 [; X/ c( J" @, k 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
