2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
6 [ \3 d Z5 B- I
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
l; n. \# s R' W# m$ _WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
