2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
+ D1 [8 k5 t9 C( X s) N) F6 u: X* t
Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
4 X3 U+ q/ {# L# t9 H0 vWiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
