Thumbnail previews
This enables users to capture thumbnails and display them as a position preview when sliding through the seek bar. There are three separate implementations of the thumbnail previews feature:
DASH-IF thumbnail previews
Harmonic WebVTT thumbnail previews
HLS I-Frame thumbnail previews
DASH-IF thumbnail previews
This feature enables users to capture thumbnails from DASH VOD and LIVE streams.
Thumbnails have to be advertised in the DASH manifest as per DASH-IF Interoperability Points 4.3. Please refer to chapter 6.2.6 Tiles of thumbnail images for the details.
See DASH-IF thumbnails.
Harmonic WebVTT thumbnail previews
The Harmonic VOS interface enables users to capture thumbnails from DASH and HLS Live and VOD streams and display them as a position preview when sliding through the seek bar. Live StartOver, CatchUp and Long CatchUp are also supported.
See Harmonic WebVTT thumbnails example code.
HLS I-Frame thumbnail previews
Some HLS streams provide accompanying I-Frame tracks; the CONNECT Player can make use of these additional tracks for displaying thumbnails.
