A method, system, computer program product, and computer readable storage medium provide the ability to bookmark a frame of media content. A media content user interface component that controls playback of the media content in a media player is activated. The component includes a circular progress bar. A frame within the media content is identified and bookmarked. A bookmark is displayed on the circular progress bar and reflects the location of the bookmarked frame. The bookmark is selected to begin play from the bookmarked frame.

In a program information broadcasting system, it is aimed to minimize time for retrieval of program by viewers in operating an electronic program guide or time for waiting when applying for subscription. As a program information broadcasting system, program elements constituting a broadcasting program are divided into a plurality of items and are turned to data at a center, and a master data 21 of a program information to recognize the program is prepared. From the data constituting the master data, minimal necessary items for preparation of a program table are extracted, and a program basic information 22 is prepared. Said master data and said program basic information are transmitted simultaneously with the broadcasting, and said program basic information is received, reproduced and displayed before receiving of the master data at a receiving terminal unit 31 is completed. As a result, the program basic information having far less amount of data than the master data can be incorporated, and it is possible to minimize the time required for storage of the data in memory of the receiving terminal unit.

An embodiment of the present disclosure discloses a method and a device for processing streaming media. The method comprises: receiving time shifting instructions coming from users in a process of playing streaming media files, wherein the time shifting instructions comprise a target time point; determining TS (Transport Stream) segments corresponding to the target time point according to index files of the segments corresponding to the streaming media files; determining location information of a key frame closest to the target time point in the TS segments; playing the TS segments from the location information of the key frame. According to the embodiment of the present disclosure, the TS segments can be directly played from the key frame closest to the target time point of time shifting, so that the time shifting accuracy can be improved in a process of playing the streaming media files.

A system for gradually implementing network services to end users includes substantially redundant first and second control networks, connectable to the end users through a routable communications network. The first control network provides a first service capability to all the end users. The second control network provides a second service capability to a first portion of the end users, the second service capability replacing the first service capability of the first portion of the end users. The second control network subsequently provides the second service capability to a second portion of the end users, while continuing to provide the second service capability to the first portion, the second service capability replacing the first service capability of the second portion of the end users. The second service capability provided to the second portion of the end users may include revisions based on feedback from the first portion of end users.

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 a primary multicast video stream and a secondary multicast video stream to a media device. The secondary multicast video stream is limited to intra-coded frames (I-frames) extracted from the primary multicast video stream. Transmission of each intra-coded frame (I-frame) of the secondary multicast video stream is delayed with respect to transmission of a corresponding I-frame of the primary multicast video stream. The delay is based on an amount of writing time to satisfy a buffer threshold of a video content buffer at the media device to prevent a noticeable time shift of video displayed by the media device when the media device switches from outputting the secondary multicast video stream to outputting the primary multicast video stream.

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.

A computing device generates a file that comprises a track box that contains metadata for a track in the file. Media data for the track comprises a sequence of samples. Each of the samples is a video access unit of multi-layer video data. As part of generating the file, the computing device generates, in the file, an additional box that documents all of the samples containing at least one Intra Random Access Point (IRAP) picture.

Described is perceptually near-lossless video summarization for use in maintaining video summaries, which operates to substantially reconstruct an original video in a generally perceptually near-lossless manner. A video stream is summarized with little information loss by using a relatively very small piece of summary metadata. The summary metadata comprises an image set of synthesized mosaics and representative keyframes, audio data, and the metadata about video structure and motion. In one implementation, the metadata is computed and maintained (e.g., as a file) to summarize a relatively large video sequence, by segmenting a video shot into subshots, and selecting keyframes and mosaics based upon motion data corresponding to those subshots. The motion data is maintained as a semantic description associated with the image set. To reconstruct the video, the metadata is processed, including simulating motion using the image set and the semantic description, which recovers the audiovisual content without any significant information loss.

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.
