EVS XSnano, Configuration Manual

Page: 89 / 198

General Description
The interpolation process aims at reducing the vertical jitter of the pictures that is present
during slow-motion replays. This vertical jitter is actually caused by a violation of the
frame parity when playing back the pictures at less than 100 % speed.
The process consists in re-building new frames to produce a more transparent result.
These frames have to be interpolated, that is calculated by making suitably weighted
averages of adjacent lines.
There are two interpolation modes: the two-line interpolator and the four-line interpolator.
They are not mutually exclusive:
• The two-line interpolator reduces the vertical jitter, but also the vertical bandwidth.
• The four-line interpolator makes it possible to have perfectly steady pictures, but
reduces even more the vertical bandwidth.
Note
All VTRs use interpolation in PLAY VAR mode.

3.3.5. PC LAN Settings
User Interface
The PC LAN settings allow the MTPC board of an EVS server to communicate and
exchange information with other EVS hardware on a setup.
The PC LAN settings are displayed on the Server tab in the server-based application
(2
nd
page) and web-based interface in the advanced mode.
