Systems and methods are described for operating a group watching session. Group communication is initiated for a group watching session displaying a media content item. A bandwidth available to at least one computing device participating in the group watching session is determined. A group communication mode for a segment of the media content item is determined. A communication parameter of the group communication and/or a buffering parameter for the media content item is set in response to determining the group communication mode for the segment of the media content item and the bandwidth available to each computing device participating in the group watching session.

A content delivery server is configured to: receive a request for a chunk of a segment of a video stream, the segment of the video stream including a series of chunks, each of the chunks including a set of video frames, a first of the chunks being aligned with a first Instantaneous Decoder Refresh frame in the video stream, and a second of the chunks being aligned with a second subsequent Instantaneous Decoder Refresh frame in the video stream; determine whether the request was received during a first interval or a second subsequent interval of an intra period between the first of the chunks and the second of the chunks; output the first of the chunks or the second of the chunks for transmission based on the determination of whether the request was received during the first interval or the second interval.

A method is disclosed including setting, at a server, a server VSYNC signal to a server VSYNC frequency. The server VSYNC signal corresponding to generation of video frames during frame periods for the server VSYNC frequency. The method including setting, at a client, a client VSYNC signal to a client VSYNC frequency. The method including sending compressed video frames from the server to the client over a network using the server VSYNC signal, wherein the compressed video frames are based on the generated video frames. The method including decoding and displaying, at the client, the compressed video frames. The method including analyzing the timing of one or more client operations to adjust the relative timing between the server VSYNC signal and the client VSYNC signal, as the client receives the compressed video frames.

A content access device uses local audio translation for content presentation. The content access device receives video and first audio data associated with a first language. The content access device uses translation software and/or other automated translation services to translate the first audio data to second audio data associated with a second language. The content access device synchronizes the video with the second audio data and outputs the video and the second audio data for presentation. The first audio data may be audio, text, and so on. The second audio data may be output as audio, text, and so on.

Provided are a video stream processing method and apparatus, an electronic device and a computer-readable medium, which relate to the field of Internet technology. An exemplary method includes: storing a video frame in an original video stream in a first buffer area by calling a video stream processing interface of a video stream processing tool; processing the video frame in the first buffer area by means of a video frame processing model to obtain a processed video frame; and on the basis of the processed video frame, generating a standard video stream corresponding to the original video stream. By means of the embodiments of the this application, the software complexity of video stream processing is effectively reduced, and the speed of video stream processing is effectively improved.

Systems, apparatuses, and methods are described for a user device controlling a playback buffer to reduce latency in a service change.

A method for streaming live video includes encoding a video stream on a server, where the server is connected to a client through a network. The server receives a request from the client for a memory address of a first video frame and checks if the memory address of the first video frame has been bit shifted in a direct mapped memory buffer to determine if the first video frame is available. The server provides a memory address of an output video frame to the client in response to the request.

A method and apparatus may be provided for building a linear media source extension (MSE) buffer from two or more nonlinear media sources using MPD chaining. The method may include parsing at least one obtained media presentation segment (MPD), and obtain a live MPD based on the at least one URL, the live MPD comprising one or more live media segments. The method may include appending the one or more ad media segments to a first MSE source buffer based on a first timing model and chaining the one or more live media segments to the one or more ad media segments by appending the one or more live media segments to the first buffer based on a second timing model. The one or more ad media segments may be dispatched and the one or more live media segments based on the first timing model and the second timing model.

Provided herein are various embodiments for synchronizing playback of audio and video. An embodiment operates by determining that a first quality video is being received at a media device. It is determined that a buffer of the media device is not large enough to buffer the first quality video long enough to synchronize an output of the high quality video with the output of the audio by one or more wireless speakers. A second quality of the video that the buffer can hold long enough to synchronize is identified, wherein the second quality of the video is lower than the first quality of the video. The media device outputs the video at the second quality and the corresponding audio to the one or more wireless speakers.

Embodiments of the present disclosure provide methods, systems and computer program products for transfer of video signals at a destination with reduced turnaround time. According to one embodiment, a method includes performing transfer of a series of video chunks of a video signal, each video chunk of the series of video chunks comprising a sequence of video frames, wherein for each video chunk, one or more processors perform a processing cycle comprising: receiving the sequence of video frames from a source; processing the received sequence of video frames to generate a processed sequence of video frames, wherein receiving of a consecutive video chunk of the series of video chunks comprising a consecutive sequence of video frames is initiated simultaneously while initiating said processing of the received sequence of video frames; and transmitting the processed sequence of video frames for consumption at a destination.
