Methods, systems, and devices secure content in memory. The content includes a lock that prohibits reading the content from memory. Prior to expiration of the lock the content cannot be read from the memory. However, a preview option allows at least a portion of the content to be accessed. The preview option provides a preview of the content. At expiration, the content is readable.

Systems and methods of performing intra-frame refresh in multimedia communications over lossy packet networks, in which a video receiver can provide packet loss feedback information to a video transmitter, and the video transmitter can respond to the feedback information, in a manner that makes efficient use of available bandwidth. By providing one or more PLI messages from the video receiver to the video transmitter based on criteria related to the detection of an eventual missing video packet and/or the determination that the quality of a current reference frame is bad, and by pausing the providing of GNACK messages from the video receiver to the video transmitter while the PLI messages are being provided to the video transmitter, the total number of video packets required for transmission/retransmission can be reduced, thereby limiting the impact of the transmitted/retransmitted video packets on the available bandwidth while enhancing the video QoE of system users.

An interactive, multi-user media delivery system having a number of media storage mediums, each of containing a particular media selection, and a number of media players structured to selectively deliver the media selection to users. Each of the media players includes a control assembly structured to selectively control and regulate delivery of the media selection to the user, and at least one of the media players is selectively designatable as a slave unit. A master control assembly is further provided and is operatively associated with the media players, a connectivity assembly being included to establish a communicative link at least between the slave unit(s) and the master control assembly. The master control assembly is further structured to receive synchronization data from each of the media players, and to simultaneously and uniformly control the delivery of the media selection by the media players.

Systems and methods for stitching advertisements in streaming content are disclosed. In some embodiments, a method comprises receiving one or more advertisements. An unmarked content item may be received, the unmarked content item comprising a stream-enabled video including a set of sequential black frames. An insertion point may be identified based on a location of at least one black frame of the set of sequential black frames without requiring user input, the insertion point identified during streaming of the unmarked content item to a consumer system, the insertion point being ahead of a current playback point of the unmarked content item streaming to the consumer system. The one or more advertisements may be stitched in the unmarked content item at the insertion point. The unmarked content item may be streamed to a consumer system until the insertion point is reached, and the one or more advertisements may be streamed to the consumer system when the insertion point is reached.

A system includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the processor to perform operations including sending, via a transmitter, a primary video stream corresponding to a particular channel to a media device. The operations further include sending a secondary video stream to the media device. The secondary video stream is associated with a lower quality level than the primary video stream. Transmission of a frame of the secondary video stream is delayed with respect to transmission of a corresponding frame of the primary video stream.

Assistance information related to a tier framework may describe signaling for extractable and decodable sub-sequences based on pictures interdependencies. This may allow a video application to efficiently select pictures when performing a given trick mode.

A video content presentation terminal includes a video content receiver that is configured to receive video content and presentation override controls for the video content. The presentation override controls define presentation restrictions for the video content. The video content presentation terminal also includes an applications processor that is configured to execute applications on the video content presentation terminal. The applications include presentation format requests. The video content presentation terminal also includes a controller that is responsive to the video content receiver and the applications processor. The controller is configured to format the content that was received for presentation on a content presentation device according to the presentation override controls that were received, while preventing implementation of the presentation format requests that are made by the applications that are inconsistent with the presentation override controls. Related systems, methods and devices are described.

A computing device generates a file that comprises a media data box that encloses media content. The media content comprises a sequence of samples. Each of the samples is an access unit of multi-layer video data. Responsive to a determination that at least one access unit of a bitstream of the multi-layer video data includes a coded picture that has a picture output flag equal to a first value and a coded picture that has a picture output flag equal to a second value, the computing device uses at least two tracks to store the bitstream in the file. For each respective track from the at least two tracks, all coded pictures in each sample of the respective track have the same value of the picture output flag.

Various aspects of methods and apparatuses are described herein. Some methods may include receiving video content, receiving metadata including a hierarchical order of metadata fields, and performing an enhancement operation on at least a portion of the video content according to settings associated with at least one of the metadata fields. The enhancement operation may include a video processing operation configured to modify one or more visual characteristics of the video content. The settings associated with the metadata field(s) may be predefined in a device that receives the video content and the metadata. The enhancement operation may be performed at a time based on a time code in the video content. The enhancement operation may be performed on a bounded area of an object. The hierarchical order may correspond to a type of display technology. The hierarchical order may correspond to information associated with a manufacturer of a display.
