Synchronization
HD to HD (720P/1080i) or SD to SD (525i/625i).
HD/SD bi or tri sync reference.
Will also synchronize SD/HD output when up/down converting.
Control
Via resident Web page or active front panel
Remote control
Ethernet: Enhanced TSL UMD (V4.0) protocol in direct UDP encapsulation.
Multicast supported.
HANC data
PCM audio data (2 groups) processed. Other audio data is passed in same frame rate modes unless replaced
by processed audio.
VANC data
Passed in same frame rate modes with same format in and out. Blanked in all other modes.
Processed audio
De-embed any channel (up to 2 groups). For SDI audio must be synchronous 48kHz.
Embed to any two groups
Processed audio may be from external audio inputs or de-embedder and is simultaneously available on the
external audio outputs and as the embedder source
PCM audio has full sub-frame router, with pair gain control
PCM and non-PCM Processed audio is matched to video delay
Non-PCM audio must be 48KHz synchronous to genlock source
Simple pair routing of Non-PCM audio, gain control disabled
16, 20 & 24 bit non-pcm audio from the de-embedder or AES input is detected automatically. When detected
and selected by the router, the non-PCM data and its associated validity bit and channel status metadata is
passed unprocessed through the router and audio delay.
Signaling
Decode incoming L23, Video Index and SMPTE 2016-1 (AFD)
Real time clean conversion dependant on decoded signaling (if same frequency)
Encode L23, Video Index and SMPTE 2016-1 (AFD) and insert on output
Closed caption
Passes captions between CEA608 (SD) and the 608 compatibility space in CEA708 (HD), dropping and
repeating null packets. HD to HD passes full CEA708 packet with simple synchronisation.
