Reference Guide: Voyager E5784 and E5788 HD DSNG Encoder
ST.RE.E10137.3
NOTE…
Lower bit-rates can be achieved, in HD mode, when used in Statistical Multiplexing equipment.
Coding Resolutions
To provide optimum picture quality over the full range of supported
bit-rates, the encoded picture resolution is controlled automatically
according to the video bit-rate. Alternatively, the user can override this
and select manual control, if desired. Coding resolutions are shown in
Annex B, Technical Specification.
Internal Frame Synchroniser
An internal frame synchroniser is provided to accommodate slight
differences between the incoming frame rate and that generated by the
stable reference

used by the Encoder.
Output on Video Loss
The Encoder can be software-configured to show, in the event of video
input loss, either:
•
A test pattern (with or without ident text) (SD only)
•
A freeze frame (with or without ident text) (SD only)
•
Display Stored OSD (Only available if the Encoder has an OSD loaded).
•
Cut to a black screen (HD default)

To ensure broadcast quality it is recommended that the studio reference is fed to HYSNC.
