Output and playback control delivery for adaptive bitrate streaming
A method is disclosed for customizing an adaptive bitrate streaming session using a manifest and control tags. The method includes establishing a network connection session between a client device and a manifest delivery controller, receiving a manifest request at the manifest delivery controller from the client device, wherein the manifest request identifies a video, determining whether one or more playback control rules and/or output control rules have been set at the manifest delivery controller that apply to the video and/or the client device, and sending a manifest and control tags from the manifest delivery controller to the client device, wherein the manifest identifies locations of a plurality of adaptive bitrate chunks of the video, and wherein the control tags are associated with playback control rules and/or output control rules that the manifest delivery controller determined applied to the video and/or the client device.
1. A method of customizing an adaptive bitrate streaming session, comprising:
establishing a network connection session between a client device and a manifest delivery controller;
receiving a manifest request at said manifest delivery controller from said client device, wherein said manifest request identifies a video;
determining whether one or more playback control rules and/or output control rules have been set at said manifest delivery controller that apply to said video and/or said client device; and
sending a manifest and control tags from said manifest delivery controller to said client device, wherein the control tags are provided separate from the manifest,
wherein said manifest identifies locations of a plurality of adaptive bitrate chunks of said video,
wherein said control tags are associated with the playback control rules and/or output control rules that said manifest delivery controller determined applied to said video and/or said client device, and
wherein the manifest directly identifies the locations of the adaptive bitrate chunks rather than rely on a link and the control tags directly deliver the playback control rule information rather than rely on a link.
2. The method of claim 1 , wherein said manifest delivery controller inserts said control tags in said manifest.
3. The method of claim 1 , wherein said manifest delivery controller sends said control tags in an auxiliary control file separately from said manifest.
4. The method of claim 3 , wherein said manifest delivery controller inserts an identifier for said auxiliary control file within said manifest.
5. The method of claim 3 , wherein said manifest delivery controller stores said auxiliary control file at a location said client device can identify programmatically from attributes of said manifest.
6. The method of claim 3 , wherein said manifest delivery controller encrypts said auxiliary control file using an encryption key that was also used to encrypt said video.
7. The method of claim 1 , wherein said playback control tags refer to types of trick plays and are instructions to said client device to enable or disable said types of trick plays during playback of said video at said client device.
8. The method of claim 1 , wherein said output control tags refer to types of video outputs from said client device to external devices and are instructions to said client device to enable or disable said types of video outputs during playback of said video at said client device.
9. The method of claim 1 , wherein one of said playback control rules and/or output control rules apply to preset types of client devices.
10. The method of claim 1 , wherein one of said playback control rules and/or output control rules apply to client devices in a preset geographic area.
11. The method of claim 1 , wherein one of said playback control rules and/or output control rules apply to client devices associated with specific types of user accounts.
