( y3 ^7 g! W* f; @2 Q 10) Transmission of IR control signals to the video source devices from the TV location.
: D2 c9 `0 a3 h! {9 d 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
; ?1 h9 ?7 y3 eParallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
, w K1 p, V: i6 t4 ~ 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 P( W/ ~# k/ Y& L 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
' ^# {2 H7 a t: g2 }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
