Methods, systems, and apparatuses for scalable content data updating
Methods, systems, and apparatuses for updating content data are described herein. A single manifest file may be maintained per content item and provided to client devices with an update file. The manifest file each client device receives may not initially facilitate output of content segments. Instead, the manifest file may be a partial manifest file that initializes playback and/or facilitates output of a most-recent content segment(s). The client devices may each determine a playback timeline. And each client device may use the corresponding update file to modify the manifest file based on the determined playback timeline, resulting in a modified manifest file that facilitates output of one or more content segments associated with the playback timeline for that particular client device.
1 . A method comprising:
receiving, by each computing device of a plurality of computing devices, a manifest file and an update file associated with a content item, wherein each computing device of the plurality of computing devices receives the manifest file and the update file based on a request time associated with that computing device and the content item;
determining, by each computing device of the plurality of computing devices, based on the manifest file and the request time corresponding to that computing device, a playback timeline;
modifying, by each computing device of the plurality of computing devices, based on the update file and the playback timeline corresponding to that computing device, a parameter value in the manifest file indicating a quantity of content segments; and
sending, by each computing device of the plurality of computing devices, based on the quantity of content segments indicated by the modified parameter value in the manifest file associated with that computing device, a request for one or more content segments associated with: the content item and the playback timeline corresponding to that computing device.
2 . The method of claim 1 , wherein the content item comprises a linear content item or a live content item.
3 . The method of claim 1 , wherein the request time is associated with a time that the corresponding computing device, of the plurality of computing devices, requested the content item.
4 . The method of claim 1 , wherein each computing device of the plurality of computing devices is associated with a maximum value for a time-shift buffer associated with that computing device.
5 . The method of claim 4 , wherein the one or more content segments are associated with a playback duration that is less than or equal to the maximum value for the time-shift buffer associated with that computing device.
6 . The method of claim 1 , wherein modifying the manifest file comprises determining, by each computing device of the plurality of computing devices, based on the update file and the playback timeline corresponding to that computing device, at least one portion of the manifest file to be modified, wherein the at least one portion of the manifest file is associated with a quantity of the one or more content segments.
7 . The method of claim 6 , wherein the update file comprises at least one function associated with the quantity of the one or more content segments.
8 . A system comprising:
a plurality of computing devices, wherein each computing device of the plurality of computing devices is configured to:
receive a manifest file and an update file associated with a content item, based on a request time associated with the computing device and the content item;
determine, based on the manifest file and the request time, a playback timeline;
modify, based on the update file and the playback timeline, a parameter value in the manifest file indicating a quantity of content segments; and
send, based on the quantity of content segments indicated by the modified parameter value in the manifest file, a request for one or more content segments associated with: the content item and the playback timeline;
and
at least one second computing device configured to send the one or more content segments.
9 . The system of claim 8 , wherein the content item comprises a linear content item or a live content item.
10 . The system of claim 8 , wherein the request time is associated with a time that the corresponding computing device, of the plurality of computing devices, requested the content item.
11 . The system of claim 8 , wherein each computing device of the plurality of computing devices is associated with a maximum value for a time-shift buffer associated with that computing device.
12 . The system of claim 11 , wherein the one or more content segments are associated with a playback duration that is less than or equal to the maximum value for the time-shift buffer associated with that computing device.
13 . The system of claim 8 , wherein each computing device, of the plurality of computing devices, is further configured to determine, based on the update file and the playback timeline, at least one portion of the manifest file to be modified, wherein the at least one portion of the manifest file is associated with a quantity of the one or more content segments.
14 . The system of claim 13 , wherein the update file comprises at least one function associated with the quantity of the one or more content segments.
15 . A method comprising:
sending, to each computing device of a plurality of computing devices, a manifest file and an update file associated with a content item, wherein each computing device of the plurality of computing devices: receives the manifest file and the update file based on a request time associated with that computing device and the content item, and determines, based on the manifest file and the request time corresponding to that computing device, a playback timeline;
receiving, via each computing device of the plurality of computing devices, based on a modified parameter value, indicating a quantity of content segments, in a manifest file associated with that computing device, a request for one or more content segments associated with: the content item and the playback timeline corresponding to that computing device, wherein each computing device of the plurality of computing devices modifies, based on the update file and the playback timeline corresponding to that computing device, the parameter value in the manifest file indicating the quantity of content segments; and
causing the one or more content segments to be output at each computing device of the plurality of computing devices.
16 . The method of claim 15 , wherein the content item comprises a linear content item or a live content item.
17 . The method of claim 15 , wherein each request time is associated with a time that the corresponding computing device, of the plurality of computing devices, requested the content item.
18 . The method of claim 15 , wherein each computing device of the plurality of computing devices is associated with a maximum value for a time-shift buffer associated with the corresponding computing device of the plurality of computing devices.
19 . The method of claim 18 , wherein the one or more content segments are associated with a playback duration that is less than or equal to the maximum value for the time-shift buffer associated with the corresponding computing device of the plurality of computing devices.
20 . The method of claim 15 , wherein the plurality of computing devices comprises a plurality of user devices.
