Devices and methods for providing navigation images associated with adaptive bit rate video content
View Patent ↗Systems and methods that improve navigation within video content in an adaptive streaming environment are provided herein.
1. A method, comprising:
receiving a top level manifest file for a media asset, the media asset comprising an adaptive rate streamed video;
selecting a media segment file from the media asset having a predetermined bitrate from the top level manifest file;
receiving a first collection of thumbnail images corresponding to the media segment file, the first collection of thumbnail images corresponding to images that coarsely represent chapters throughout the duration of the media segment file; and
receiving a second collection of thumbnail images corresponding to the media segment file, the second collection of thumbnail images corresponding to images that more finely represent chapters throughout the duration of the media segment file, wherein the first collection and second collection of thumbnail images are received at different times;
using the first collection of thumbnail images to display for a user to identify video segments for playback when video receive speed is limited and the second collection of thumbnail images is not available;
using the second collection of thumbnail images to display for a user to identify video segments for playback when video receive speed is available to create the second collection of thumbnail images;
receiving a third collection of thumbnail images corresponding to the media segment file, the third collection of thumbnail images corresponding to images that more finely represent chapters throughout the duration of the media segment file;
wherein the first and second collections of thumbnail images are provided for display to the user when bandwidth is not sufficient to allow the third collection of thumbnail images to be created; and
using the third collection of thumbnail images to display for a user to identify video segments for playback when video receive speed is sufficient to allow all of the first, second and third collections of thumbnail images.
2. The method of claim 1 , wherein a tag in the top level manifest file indicates if the first collection of thumbnail images is available.
3. The method of claim 1 , further comprising: pairing each thumbnail image within the first collection of thumbnail images with a time offset or a segment number corresponding to a media segment starting point.
4. The method of claim 3 , wherein each thumbnail image is paired using a uniform resource locator (URL) for the thumbnail image.
5. The method of claim 3 , wherein the pairing is performed using a look-up table.
6. The method of claim 1 , wherein said receiving the second collection of thumbnail images is performed as a background task when processor capacity is available.
7. The method of claim 1 , wherein the first collection of thumbnail images comprises a collection of 100 thumbnail images that span from the beginning of the media segment to the end of the media segment.
8. The method of claim 1 , wherein the second collection of thumbnail images comprises a collection of thumbnail images that are periodically spaced at a time interval corresponding to a duration of corresponding media files, the thumbnail images spanning from the beginning to the end of an entire audiovisual media.
9. The method of claim 1 , wherein the first collection and second collection of thumbnail images are compressed using a standard format.
10. A system, comprising an adaptive bitrate (ABR) player, the ABR player comprising:
a processor for receiving a streaming ARB video; and
a memory connected to the processor, the memory storing code to cause the processor to perform the following steps:
receive a top level manifest file for a media asset;
select a media segment file having a predetermined bitrate from the top level manifest file;
receive a first collection of thumbnail images corresponding to the media segment file, the first collection of thumbnail images corresponding to images that coarsely represent chapters throughout the duration of the media segment file; and
receive a second collection of thumbnail images corresponding to the media segment file, the second collection of thumbnail images corresponding to images that more finely represent chapters throughout the duration of the media segment file,
wherein the first collection and second collection of thumbnail images are received at different times;
wherein the first collection of thumbnail images are used to display for a user to identify video segments for playback when video receive speed is limited and the second collection of thumbnail images is not available; and
wherein the second collection of thumbnail images are used to display for a user to identify video segments for playback when video receive speed is available to create the second collection of thumbnail images;
receive a third collection of thumbnail images corresponding to the media segment file, the third collection of thumbnail images corresponding to images that more finely represent chapters throughout the duration of the media segment file;
wherein the first and second collections of thumbnail images are provided for display to the user when bandwidth is not sufficient to allow the third collection of thumbnail images to be created; and
use the third collection of thumbnail images to display for a user to identify video segments for playback when video receive speed is sufficient to allow all of the first, second and third collections of thumbnail images.
11. The system of claim 10 , wherein the ABR player is further configured to: perform bandwidth availability estimation prior to selecting a media segment file having a predetermined bitrate.
12. The system of claim 10 , wherein the ABR player is further configured to: receive a second level manifest file for the media asset.
13. The system of claim 12 , wherein the ABR player is further configured to: determine the media segment file from the second level manifest file.
14. The system of claim 10 , wherein the ABR player is further configured to: receive multiple media files in succession.
15. The system of claim 10 , wherein the ABR player is further configured to: determine if bandwidth availability changes and adjusting media file segment selection based on available bandwidth.
16. The system of claim 10 , wherein the ABR player is further configured to: recognize a tag in the top level manifest file, wherein the tag indicates that thumbnail images are available for retrieval.
17. The system of claim 10 , further comprising: an image handler in communication with the ABR player, the image handler configured to: recognize a tag in the top level manifest file, wherein the tag indicates that thumbnail images are available for retrieval.
18. The system of claim 17 , wherein the image handler is further configured to: decompress the first collection and second collection of thumbnail images.
19. The system of claim 10 , further comprising: an application graphic user interface (GUI) in communication with the ABR player, the GUI configured to: provide a progress bar and playback location indicator to a user.
