Abstract

In some embodiments, a method may receive a seekable range position for the live edge of a live media program and a current playback time. A distance between the position and the current playback time is calculated and compared to three or more feature ranges. A first range is where the user is considered watching live, a second range is where the user is considered not watching live, and a third range is where the user state is not changed. The method enables a first feature that displays a first control indicating that the media program is in a live state for a first range. The method enables a second feature that displays a second control to allow seeking to the live edge for a third range. The method does not change whichever of the first feature or the second feature this is currently enabled for a second range.

First claim

What is claimed is:

1. A method comprising:
receiving, by a computing device, a seekable range position for a live edge of a live media program and a current playback time, the seekable range position determined based on segments in one or more manifests that are received during playback of the media program and are used to request video for the live media program;
calculating, by the computing device, a distance between the seekable range position and the current playback time;
comparing, by the computing device, the distance to three or more feature ranges, wherein a first range in the three or more feature ranges is where the playback is considered in a live state, a second range in the three or more feature ranges is where the playback is considered not in the live state, and a third range in the three or more feature ranges is where the playback is considered to be in either the live state or not in the live state;
when the distance is within the first range, enabling, by the computing device, a first feature that displays a first control indicating that the media program is in a live state;
when the distance is within the second range, enabling, by the computing device, a second feature that displays a second control to allow seeking to the live edge; and
when the distance is within the third range, not changing, by the computing device, whichever of the first feature or the second feature this is currently enabled to continue displaying whichever of the first control and the second control that is currently being displayed.

2. The method of claim 1 , wherein when the distance is within the third range, not changing a display of the first control or the second control that is currently displayed on an interface.

3. The method of claim 1 , wherein enabling the first feature comprises:
displaying the first control on an interface during playback of the media program.

4. The method of claim 3 , wherein the first control includes a message indicating the playback of the media is in the live state.

5. The method of claim 3 , wherein the first control does not perform any actions when selected.

6. The method of claim 1 , wherein enabling the second feature comprises:
displaying the second control on an interface during playback of the media program.

7. The method of claim 6 , wherein the second control, when selected, automatically seeks to the live edge.

8. The method of claim 1 , wherein the first control or the second control are displayed on an interface when a menu is enabled by a user.

9. The method of claim 1 , wherein:
when a new manifest is received, the seekable range position is increased by a time associated with a segment of the new manifest.

10. The method of claim 1 , wherein:
new manifests for intervals of the media program are received during playback of the live media program, and
each new manifest increases the seekable range position of the live edge.

11. The method of claim 1 , further comprising:
determining the first range, the second range, and the third range using a threshold that defines a maximum time behind the live edge that is still considered live.

12. The method of claim 11 , wherein:
the first range is from the seekable range position of the live edge to a first value;
the third range is from the first value to a second value; and
the second range is from the second value to a third value.

13. The method of claim 12 , wherein the second value is a larger distance from the seekable range position of the live edge than a distance from the seekable range position of the live edge to the first value, and the third value is a larger distance from the seekable range position of the live edge than a distance from the seekable range position of the live edge to second value.

14. The method of claim 1 , wherein when the distance is within the third range, performing:
retrieving a previous range associated with the distance; and
keeping either the first feature or the second feature enabled based on the previous range.

15. A non-transitory computer-readable storage medium containing instructions, that when executed, control a computer system to be configured for:
receiving a seekable range position for a live edge of a live media program and a current playback time, the seekable range position determined based on segments in one or more manifests that are received during playback of the media program and are used to request video for the live media program;
calculating a distance between the seekable range position and the current playback time;
comparing the distance to three or more feature ranges, wherein a first range in the three or more feature ranges is where the playback is considered in a live state, a second range in the three or more feature ranges is where the playback is considered not in the live state, and a third range in the three or more feature ranges is where the playback is considered to be in either the live state or not in the live state;
when the distance is within the first range, enabling a first feature that displays a first control indicating that the media program is in a live state;
when the distance is within the second range, enabling a second feature that displays a second control to allow seeking to the live edge; and
when the distance is within the third range, not changing whichever of the first feature or the second feature this is currently enabled to continue displaying whichever of the first control and the second control that is currently being displayed.

16. The non-transitory computer-readable storage medium of claim 15 , wherein when the distance is within the third range, not changing a display of the first control or the second control that is currently displayed on an interface.

17. The non-transitory computer-readable storage medium of claim 15 , wherein:
when a new manifest is received, the seekable range position is increased by a time associated with a segment of the new manifest.

18. The non-transitory computer-readable storage medium of claim 15 , wherein:
new manifests for intervals of the media program are received during playback of the live media program, and
each new manifest increases the seekable range position of the live edge.

19. The non-transitory computer-readable storage medium of claim 15 , wherein when the distance is within the third range, performing:
retrieving a previous range associated with the distance; and
keeping either the first feature or the second feature enabled based on the previous range.

20. An apparatus comprising:
one or more computer processors; and
a non-transitory computer-readable storage medium comprising instructions, that when executed, control the one or more computer processors to be configured for:
receiving a seekable range position for a live edge of a live media program and a current playback time, the seekable range position determined based on segments in one or more manifests that are received during playback of the media program and are used to request video for the live media program;
calculating a distance between the seekable range position and the current playback time;
comparing the distance to three or more feature ranges, wherein a first range in the three or more feature ranges is where the playback is considered in a live state, a second range in the three or more feature ranges is where the playback is considered not in the live state, and a third range in the three or more feature ranges is where the playback is considered to be in e
