Disclosed is a method and system for transmitting and reproducing a video of a dynamic bitrate using a plurality of channels. A video transmission method may transferring frames of a video to N encoders using an interleaving scheme, N denoting a first natural number greater than or equal to 2, generating N video streams by encoding the frames using the N encoders, each of the N video streams corresponding to one of the N encoders, and transmitting each of the N video streams as an independent stream.

A moving image distribution server 12 transfers, by streaming, data of a plurality of moving images representing the same space. A moving image reproduction apparatus 10 separates audio data from any one of the moving images and outputs the audio data after a predetermined period of delay. The moving image reproduction apparatus 10 also separates image data from another moving image and outputs the image data in synchronization with audio. When a user performs an image switching operation, the moving image reproduction apparatus 10 acquires data of a moving image that has been switched from another moving image, separates image data therefrom, and starts outputting the image data given the same PTS as the audio data continuously being output.

A system includes a primary playback system and a secondary playback system. The primary playback system plays back selected content. The secondary playback system plays back supplemental media associated with the content played back on the primary playback system. A media playback function (such as associated with the secondary playback system) monitors playback of the content on the primary playback system. For example, a first processing thread of the media playback function initially synchronizes playback of supplemental media on the secondary playback system with respect to playback of the content on the primary playback system. Based on further monitoring of playing back the content on the secondary playback system, a second processing thread of the media playback function verifies synchronization (and, when needed, initiates re-synchronization) of playback of the supplemental media on the secondary playback system with respect to playback of the content on the primary playback system.

Providing a coordinated primary media stream with an aggregate supplemental media stream is disclosed. A request is received from an end user device associated with a user for supplemental media. Metadata and a broadcast time associated with a primary media stream transmitted to the end user device are determined. Based on the metadata and the broadcast time, first supplemental media from a first account of the user on a first platform and second supplemental media from a second account of the user on a second platform are determined. The first supplemental media and the second supplemental media are merged into an aggregate supplemental media stream. The aggregate supplemental media stream is streamed in synchronization with the primary media stream.

A first example playback device includes one or more processors and a non-transitory computer-readable medium storing instructions that, when executed by the one or more processors, cause the first playback device to perform functions. The functions include generating a mixed audio signal comprising one or more components of a first audio stream and one or more components of a second audio stream; and playing the mixed audio signal, where the one or more components of the second audio stream of the mixed audio signal played by the first playback device are played in synchrony with a second playback device configured to play the second audio stream. An example non-transitory computer-readable medium and an example method, both related to the first example playback device, are also disclosed herein.

The method includes: A first electronic device displays a control center on a first interface, where the control center includes a device list including one or more electronic devices, and the one or more electronic devices and the first electronic device are in a same content continuation system. The first electronic device receives a first selection operation of selecting a second electronic device from the one or more electronic devices by a user. In response to the first selection operation, the first electronic device determines whether the first electronic device is a source device or a target device of a current content continuation task. If the first electronic device is the target device of the current content continuation task, the first electronic device switches content in the second electronic device to the first electronic device for continuous playing.

A speech video generation device according to an embodiment includes a first encoder that receives an input of a first person background image of a predetermined person partially hidden by a first mask, and extracts a first image feature vector from the first person background image, a second encoder, which receives an input of a second person background image of the person partially hidden by a second mask, and extracts a second image feature vector from the second person background image, a third encoder, which receives an input of a speech audio signal of the person, and extracts a voice feature vector from the speech audio signal, a combining unit, which generates a combined vector of the first image feature vector, the second image feature vector, and the voice feature vector, and a decoder, which reconstructs a speech video of the person using the combined vector as an input.

A method, apparatus and computer program product enable multiple timeline support in playback of omnidirectional media content with overlay. The method, apparatus and computer program product receive a visual overlay configured to be rendered as a multi-layer visual content with an omnidirectional media content file (30). The omnidirectional media content file is associated with a first presentation timeline. The visual overlay is associated with a second presentation timeline. The method, apparatus and computer program product construct an overlay behavior definition file associated with the visual overlay (32). The overlay behavior definition file indicates a behavior of the second presentation timeline with respect to the first presentation in an instance that a pre-defined user interaction switch occurs during a playback of the omnidirectional media content file.

A system includes a primary playback system and a secondary playback system. The primary playback system plays back selected content. The secondary playback system plays back supplemental media associated with the content played back on the primary playback system. A media playback function (such as associated with the secondary playback system) monitors playback of the content on the primary playback system. For example, a first processing thread of the media playback function initially synchronizes playback of supplemental media on the secondary playback system with respect to playback of the content on the primary playback system. Based on further monitoring of playing back the content on the secondary playback system, a second processing thread of the media playback function verifies synchronization (and, when needed, initiates re-synchronization) of playback of the supplemental media on the secondary playback system with respect to playback of the content on the primary playback system.

Systems and methods for generating a graphically animated audience are disclosed. Biometric data is captured via a sensor during display of content via a first device. The biometric data is stored in association with metadata for the content, and is mapped to a graphical representation. Based on the mapping of the biometric data to the graphical representation and the metadata, a graphical animation is generated for display in synchronization with displaying of the content via a second device.
