In some embodiments, a method receives a request from a client device. The request includes location information for an update to a media presentation description for a media presentation. The method uses the location information to determine that the client device has not received a first segment based on the location information. The media presentation description is currently sending updates for a second segment. The location information is used to identify that the update to the media presentation description should include the first segment and the second segment. The method sends an instance of the media presentation description that includes update information for the first segment and the second segment to update a stored version of the media presentation description for the client device.

Failure recovery using differential media presentation descriptions for video streaming

In some embodiments, a method receives a manifest presentation description for a media presentation. The manifest presentation description includes an opportunity that requires resolution to determine supplemental content for the opportunity. A request to resolve the opportunity is sent where information for the supplemental content that is received from the request is inserted in an instance of the media presentation description. The method stores the information for the supplemental content in association with an identifier for the opportunity. An update to the manifest presentation description is received where the update includes the opportunity. The method retrieves the information for the supplemental content that was stored in association with the identifier for the opportunity and inserts the information for the supplemental content into the instance of the update to the manifest presentation description.

Client based storage of remote element resolutions

In some embodiments, a method determines an element is associated with a value in a manifest description presentation for a media presentation being played. The value indicates the element of the manifest description presentation is part of a group. The method reviews the manifest description presentation to determine a plurality of elements that are associated with the value and sends a request to a device to resolve the plurality of elements using information from one of the elements. Information for supplement content is received for the group where the information for the supplemental content is inserted in the manifest description presentation in place of the plurality of elements.

Identification of elements in a group for dynamic element replacement

In some embodiments, a method sends a first instance of a media presentation description to a client device for a media presentation. The first instance of the media presentation description includes location information for a patch update. The location information for the patch update is received in a request from the client device. The method uses the location information to identify the patch update to the media presentation description and sends a second instance of the media presentation description that includes update information from the patch update to update a stored version of the media presentation description for the client device.

Media presentation description patches for video streaming

In some embodiments, a method sends a first instance of a media presentation description including first status information to a client. The first status information identifies a break from a stream of a media presentation for insertion of supplemental content. The method receives a request for a second instance of the media presentation description. The request includes information from the first status information that reverted the client back to the stream of the media presentation after insertion of the supplemental content. Then, the method sends the second instance of the media presentation description based on receiving the request from the client including the information from the first status information.

Supplemental content insertion using differential media presentation descriptions for video streaming

In some embodiments, a method receives a request for a segment of video from a client. The request is associated with an identity. The method maps the segment to a variant value in a representation for the identity and selects a variant for the segment from a plurality of variants based on the variant value in the representation. A first segment of a first variant of the plurality of variants includes a first marker and a second segment of a second variant of the plurality of variants includes a second marker. The variant of the segment is then delivered to the client.

Stateless re-discovery of identity using watermarking of a video stream

In some embodiments, a method receives a plurality of swatch configurations that each define combinations for lightness values, saturation values, and hue values and receives information associated with a characteristic of an image. A swatch configuration is selected based on the information where the swatch configuration defines a plurality of combinations for lightness values, saturation values, and hue values. The method generates a plurality of colors using the plurality of combinations for lightness values, saturation values, and hue values by varying at least one of the saturation value, the lightness value, and the hue value for the plurality of colors. The plurality of colors are applied to an interface that is displaying the image.

Color accent generation for images in an interface

In some embodiments, a method sends a first instance of a media presentation description to a client for a first set of segments of a media presentation. The first instance of the media presentation description includes status information based on the first set of segments in the media presentation. A request is received for an update to the media presentation description where the request includes the status information. The method uses the status information to identify a latest segment that the client has already received in the media presentation. Then, the method sends a second instance of the media presentation description for a second set of segments that occur after the latest segment in the media presentation as an update to the first instance of the media presentation description. The second instance of the media presentation description excludes at least a portion of information for first set of segments.

Differential media presentation descriptions for video streaming

In one embodiment, a method receives an image of video content for a video offered by a video delivery service. The method analyzes pixels in the image to determine color attributes of the pixels, the color attributes including a lightness attribute and a hue attribute. Lightness counts for the image based on the lightness attribute and hue group counts based on the hue attribute are generated for the pixels. The method selects a lightness classification from lightness classifications based on the lightness counts and selects a hue group from hue groups based on the hue group counts. The lightness classification and the hue group classification are sent to a client device to allow the client device to generate a color using the lightness classification, the hue group classification, and a saturation value, the color being applied to an interface on the client device that is displaying the image.

Derivation and application of color accents for images in a video delivery system interface

In some embodiments, a method receives a request from a client including first status information. The status information was included in a first instance of a media presentation description for a first set of segments of a stream of a media presentation and identified a break from the stream of the media presentation for insertion of supplemental content. The method uses the first status information to identify supplemental content for the client. A second instance of the media presentation description is sent for at least a portion of the supplemental content. The second instance of the media presentation description includes second status information that reverts the client back to the stream of the media presentation after insertion of the supplemental content.
