Intermediate key frame selection and animation
11582531 · 2023-02-14 · ·

Mechanisms provide intermediate key frame animation during a media seek. A streaming server receives a seek request from a client device while the streaming server provides the client device with a media stream. The seek request is made when the media stream is playing at an initial location and the seek request includes a request to play the media stream from a seek location. In some embodiments, intermediate key frames before the seek location are identified. In other instances, intermediate key frames between the initial location and the seek location are identified. These intermediate key frames are provided to the client device for display before the media stream begins playing at the seek location.

Local cache maintenance for media content

A media device and methods that identify playback states reachable from a current content playback state and identify a reachable state that is likely to occur, are disclosed. A memory associated with the media device may receive frames that enable a smooth transition between the playback state and the reachable state. The media device may receive frames that correspond to points in the content that are separated by an amount of time that is proportional to the playback rate of the likely state. The frames may be frames corresponding to an image that may be played back at the playback rate of the likely state.

Generating structured data from screen recordings
11582509 · 2023-02-14 · ·

Generating structured data from screen recordings is disclosed, including: obtaining, from a client device, a screen recording of a user's activities on the client device with respect to a task; performing, at a server, video validation on the screen recording, including by determining whether the screen recording matches a set of validation parameters associated with the task; and generating a set of structured data based at least in part on the video validation.

Methods and apparatuses for combining and distributing user enhanced video/audio content

Methods and apparatuses are provided, which may be implemented to combine and distribute user enhanced video and/or audio content.

Video processing method and apparatus, and storage medium
11582506 · 2023-02-14 · ·

Disclosed are a video processing method and apparatus, and a storage medium. The method includes: receiving a selection instruction of having selected one or more video streams or key frames of the one or more video streams to be browsed; setting video stream thumbnails generated from the one or more video streams or key frame thumbnails generated from the key frames to a scene thumbnail to generate a picture layout stream according to the selection instruction, where the scene thumbnail is generated according to a scene displayed in an augmented reality/virtual reality (AR/VR) interface; and presenting the picture layout stream in the VR/AR interface, and providing a virtual layout interface of multiple video stream pictures.

Network Video Streaming with Trick Play Based on Separate Trick Play Files
20180007451 · 2018-01-04 · ·

Network services encode multimedia content, such as video, into multiple adaptive bitrate streams of encoded video and a separate trick play stream of encoded video to support trick play features. The trick play stream is encoded at a lower encoding bitrate and frame rate than each of the adaptive bitrate streams. The adaptive bitrate streams and the trick play stream are stored in the network services. During normal content streaming and playback, a client device downloads a selected one of the adaptive bitrate streams from network serviced for playback at the client device. To implement a trick play feature, the client device downloads the trick play stream from the network services for trick play playback.

Method and Apparatus for Playing a Multimedia File From a Re-Positioned Playing Point
20180014074 · 2018-01-11 ·

The present disclosure provides a method for playing a multimedia file from a re-positioned playing point, including: receiving a jump instruction, obtaining a re-positioned playing point specified by the jump instruction; obtaining a subtitle time axis of a current multimedia file, wherein the subtitle time axis records a start point of each subtitle of the multimedia file; in a jump direction specified by the jump instruction, searching start points recorded by the subtitle time axis for a start point which is closest to the re-positioned playing point as an actual re-positioned playing point; and playing the multimedia file from the actual re-positioned playing point. The present disclosure also provides an apparatus for playing multimedia file from a re-positioned playing point.

Systems and methods for reconciling playback using progress point information
11711586 · 2023-07-25 · ·

The systems and methods are described herein for playback of content based on progress point information. The systems and methods detect nearby media devices to transmit or request progress point information. Based on the communicated progress point information, the system may generate an option to play back content at a point within the content up to which content was last consumed. When content providers offer different versions of one content item and the user does not select to play back content from the content provider associated with the progress point information, the system determines a proper playback point in other content providers.

Adaptive bit-rate methods for live broadcasting

The following describes techniques to maintain continuity of a live media stream. A media stream includes a first distribution layer with a first set of key frames and a set of delta frames succeeding key frames in the first set of key frames. The media stream also includes a second distribution layer including a second set of key frames, where the second set of key frames contains fewer key frames than the first set of key frames. Using the first and second distribution layers, a client device may subscribe to the media stream with a minimized start-up time and optimized quality of experience among varying complexity of the media content and dynamic network conditions.
