2 R# w+ [3 C! [. v9 ]# H. S; I; j8) Configurable expansion I/O connector enabling easy integration with existing host
# g' m$ b H) |! Q+ s systems.
1 m( e2 ^( L/ w! Y1 X 9) HCI interface to the host CPU to enable flexible application development at the host level.
/ C, S8 Z1 O P; S- G 10) Transmission of IR control signals to the video source devices from the TV location.
" r& C+ Y: E6 S) f+ \ 2 Functional Specifications
The WAV3000 supports standard MPEG Transport Stream input and output in either
' |! `$ T, R' |3 f$ g/ G+ p! \ Parallel or Serial mode.
The Tx unit transmits the compressed MPEG TS signal to the Rx unit over the air, using the
' B( c% y. \. y6 |, X WiViTM wireless networking technology at 5 GHz.
Supports 4.9 to 5.9 GHz frequency band and is controlled by software to comply with
X x" N3 u* l$ ~7 [' D* K& y 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
h3 P, A: @8 x" [4 k# N 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
