Various embodiments are described herein for systems and methods that can be used to operate a media transmission network. In at least one embodiment, the media transmission network comprises a plurality of media processing devices configured to receive and process media streams based on control data. The media transmission network also comprises a controller coupled to the plurality of media processing devices and configured to generate a control signal for some or all of the media processing devices in the network. The controller is configured to determine the timing at which to transmit the control signal to a respective media processing device in order for the instructions in the control signal to be executed at the same time as the media data is received. The controller determines the transmission timing of each control signal by determining the latencies and delays of the network and the devices, such as, for example, network latency, processing delay, and/or control delay.

Methods and systems provide synchronized sharing of multimedia between multiple devices. The multiple devices may form an ad-hoc network for sharing of multimedia. In an embodiment, group members may have playlist manipulation privileges such as pausing, rewinding, fast forwarding, or adding tracks to the playlist. A system may stream or distribute content according to the shared playlist. Playback may be synchronized for group members so that everyone is exposed to a same part of the content as the same time.

The invention relates to a system and a corresponding method for sharing multi-media content among a plurality of users. The invention further relates the corresponding devices and a corresponding computer program for conducting the sharing of multi-media content. The system comprises a first device comprising means for generating an invitation and a play time stamp and the system further comprises means for transmitting the play time stamp and the invitation to at least one second device. The system also comprises a third device that may generate a system time and distribute the system time. The at least one second device may play multi-media content synchronous to playback of the same multi-media content at the first device.

A mobile device responds in real time to media content presented on a media device, such as a television. The mobile device captures temporal fragments of audio-video content on its microphone, camera, or both and generates corresponding audio-video query fingerprints. The query fingerprints are transmitted to a search server located remotely or used with a search function on the mobile device for content search and identification. Audio features are extracted and audio signal global onset detection is used for input audio frame alignment. Additional audio feature signatures are generated from local audio frame onsets, audio frame frequency domain entropy, and maximum change in the spectral coefficients. Video frames are analyzed to find a television screen in the frames, and a detected active television quadrilateral is used to generate video fingerprints to be combined with audio fingerprints for more reliable content identification.

A device for processing video data can be configured to receive a configuration record for decoding a bitstream of the video data, wherein the configuration record for the bitstream includes a toolset indication syntax element that includes information identifying, from a set of video decoding tools, tools that are required to decode the bitstream associated with the configuration record; based on the toolset indication syntax element, determine whether to retrieve the bitstream associated with the configuration record; and based on the determination to retrieve the bitstream associated with the configuration record, retrieve the bitstream and outputting the bitstream to a video decoder for decoding.

A file encapsulation method and apparatus, a file transmission method and apparatus, a file decoding method and apparatus, an electronic device, and a storage medium. The file encapsulation method includes: obtaining an encoded target video and temporal layer information of samples determined during encoding of the target video, encapsulating the encoded target video according to the temporal layer information of the samples to generate a first encapsulated file, the first encapsulated file including the temporal layer information of the samples, and transmitting the first encapsulated file to a first device.

A system and method are provided for an AV device for use with a video player, one or more speakers, and encoded AV data. The encoded AV data includes multiplexed encoded video data and encoded audio data. The AV device is connected to the speakers via wireless channels. The AV device is able to determine channel delays associated with each wireless channel; synchronize program clocks of the video player and speakers; determine and modify buffer levels of each speaker; demultiplex the encoded AV data to obtain encode video data and encoded audio data; and provide prefetched portions of encoded audio data based on buffer levels.

A method is disclosed including setting, at a server, a server VSYNC signal to a server VSYNC frequency defining a plurality of frame periods. The server VSYNC signal corresponding to generation of a plurality of video frames at the server during the plurality of frame periods. The method including setting, at a client, a client VSYNC signal to a client VSYNC frequency. The method including sending a plurality of compressed video frames based on the plurality of video frames from the server to the client over a network using the server VSYNC signal. The method including decoding and displaying, at the client, the plurality of compressed video frames. The method including analyzing the timing of one or more client operations to set the amount of frame buffering used by the client, as the client receives the plurality of compressed video frames.

An Interactive Media Event (IME) system includes a sync server, a first user device, and a second user device, each device is coupled to the server. The server executes computer instructions instantiating a content segment engine which outputs a Party matter to the second user device and instantiates an IME engine which receives, from the second user device, a later reaction to the Party matter. The IME engine synchronizes the later reaction with the Party matter. The Party matter may include a media event and a prior reaction to the media event received from the first user device. The media event includes a primary content segment and synchronization information associated therewith. The prior reaction and/or the later reaction may be synchronized to the primary content segment and/or to each other using the synchronization information. A reaction may include chat data captured during the Party.

Systems and methods for enhancing user experience in accessing media of a certain content type by outputting the media on a nearby device that is better suited for access. For example, a media guidance application may determine that a user is accessing, on his/her smartphone, a digital page (e.g., a website, a newsfeed, etc.) that features embedded content (e.g., photos, movies, music, etc.). In response to determining that the user has navigated to an embedded content, such as a video clip, the media guidance application may determine a device in the vicinity of the user that is better suited than the user's smartphone for playback of the video clip. For example, a nearby smart television may have a larger screen, better sound output, and a better display resolution than the smartphone. As a result, the media guidance application may cause the smart television to output the video clip.
