Auto
, which is fine if the
stream complies with the standard, the Electra VS uses the
language associated with the teletext indicated by the ID.
Otherwise, specify the language manually using the ISO

(e.g., enter eng for English, spa for Spanish, etc.).
Default rendition:
if set to
true
, the rendition should be played by
default in the absence of information from the user indicating a
different choice. It shall be unique among the subtitles.
Auto-select rendition
: set to
true
by default. A player may
automatically select a rendition between the ones with auto-select set
to true. Only one rendition with the same language shall be
auto-selectable. Auto-select shall is usually set to
false
for subtitle for
hearing impaired.
Forced rendition
: set to
false
by default. If set to
yes
, the rendition
contains content which is considered essential to play. When selecting
a forced rendition, a player should choose the one that best matches
the current playback environment (e.g. language).
Rendition NAME attribute

Auto
by default. Fill the NAME
attribute of the
#EXT-X-MEDIA

subtitles.
Input: ES Subtitle Tab
The
ES Subtitle
tab lets you get subtitles from an SDI input and include
them in WebVTT format in an HLS output.
To do so, you must link the Teletext output of an
SDI input
processing
component to the
ES subtitle
input of the HLS output.
For each linked ES subtitle input, an
Input: ES Subtitle
tab is created
in the
HLS
output processing component.
