Particular embodiments provide a system to determine ad segments in a video asset to enable subsequent ad replacement in video programs. The system is included in a multiple service operator (MSO) system that broadcasts video programs via a broadcast schedule. The MSO may not know the location of the ad segments in the video asset. To determine the ad segments, the MSO uses a classifier to classify video program segments and advertisements in the video asset. The classifier may be integrated with an nDVR system. By integrating with the nDVR system, particular embodiments may determine user behavior information, such as trick play commands, from the nDVR system. The classifier may use the user behavior information to detect ad segments in the video asset. In one embodiment, the classifier may fuse outputs from different detectors to detect and validate ad segments in the video program.

Systems and methods for rewinding a video to a point before the video was first viewed. Video transmitted by a media source is cached by a remote server. Upon a trick-play request for the video, the server generates a rewind stream that includes the video that was transmitted by the media source before the user started to view the video. Upon receiving the rewind stream, the user's equipment may cache the rewind stream in a rewind buffer and rewind or play from the rewind buffer. The server may also generate and transmit a forward stream of the video that the media source has not yet transmitted. The user's equipment may cache the forward stream in a forward buffer. To perform trick-play operations with the video, the user's equipment may migrate the playback of the video to the rewind and forward buffers and rewind or fast-forward the video from the buffers.

A media stream sending method provides a live media stream for a client that enters a live broadcast room. A proxy server receives, from a first client, a first live broadcast room request message for requesting to enter the live broadcast room; the proxy server determines a role of the first client based on the first live broadcast room request message; and if the role of the first client is a slave user, the proxy server sends a first live media stream cached in the proxy server to the first client, where the first live media stream is a media stream that is sent by a media server to a second client through the proxy server, and a role of the second client is a master user.

In some embodiments, an electronic device presents a plurality of representations of content items that are available on a respective channel in response to successfully subscribing the respective channel. In some embodiments, an electronic device plays content that is provided by a channel in a unified media browsing application. In some embodiments, an electronic device presents information about subscribing to a channel based on content consumption activity of the user on the electronic device in accordance with some embodiments of the disclosure.

A television set is capable of receiving both broadcast program from television station and corresponding digital file of the same contents from a server station through internet. The television set keeps information of time limit for the server station to surely provide the file. The television set automatically downloads the file when the time limit comes close or the time limit information is failed to be kept. The television set keeps URL for the moving image program enjoyed upon turning-off of the television set until the next turning-on for instantly enjoying the moving image content provided at the URL. User who turning-on the television set or changing the channel with any program not in mind to feel interest in the program on display by chance can enjoy the program from the beginning by means of downloading corresponding digital file of the same contents through internet by an automatic link.

Disclosed are methods and systems for controlling the playback and recording of television programming containing interactive applications. In particular, the disclosed methods and systems detail how “trick modes” can be handled when playing applications that are distributed with the television programming.

Systems and methods are disclosed for enabling Internet users to schedule recordings of electronic programming content. One method includes displaying on a web page, over the Internet, a user interface element associated with an advertisement for electronic programming content; wherein selection of the user interface element, by a user of a web browsing device, initiates a recording device of the user, separate from the web browsing device, to schedule a recording of the electronic programming content. Another method for enabling Internet users to request television content includes displaying on a web page, over the Internet, a user interface element associated with an advertisement for television content; wherein a user's selection of the user interface element initiates a request for the advertised television content from a carrier that provides television service to the user.

A media broadcasting method includes: receiving, by a server, a playing request transmitted by a terminal device, the playing request requesting to play media segments; querying, by the server, a segment index file of the media segments according to the playing request; determining, by the server, a target segment set according to the segment index file of the media segments, the target segment set comprising segments for which the terminal device has playing authority in the media segments; determining, by the server, a target segment index file corresponding to the target segment set; and transmitting, by the server, the target segment index file to the terminal device.

A system and method for searching and displaying multimedia search results is disclosed herein. An embodiment operates by determining that an interface including one or more previously saved searches is displayed, each of the previously saved searches corresponding to a set of one or more search terms. An updated plurality of search results is received for each of the previously saved searches from a remote server. A grouping of the plurality of search results for each of a plurality of different search terms is displayed across a plurality of individual time periods.

Systems and methods for rewinding a video to a point before the video was first viewed. Video transmitted by a media source is cached by a remote server. Upon a trick-play request for the video, the server generates a rewind stream that includes the video that was transmitted by the media source before the user started to view the video. Upon receiving the rewind stream, the user's equipment may cache the rewind stream in a rewind buffer and rewind or play from the rewind buffer. The server may also generate and transmit a forward stream of the video that the media source has not yet transmitted. The user's equipment may cache the forward stream in a forward buffer. To perform trick-play operations with the video, the user's equipment may migrate the playback of the video to the rewind and forward buffers and rewind or fast-forward the video from the buffers.
