A video is transmitted from a transmitting-side to a receiving-side by a preference transmission method that is any of a first transmission method and a second transmission method. The first transmission method transmits an original video as the video. The second transmission method generates a reduced video by reducing the original video and transmits the reduced video as the video. When receiving the reduced video, the receiving-side applies a super-resolution technique to the reduced video to improve the image quality. A first delay time is a transmission time by the first transmission method. A second delay time is a sum of a transmission time by the second transmission method and the super-resolution processing time. A transmission method corresponding to a shorter one of the first delay time and the second delay time is selected as the preference transmission method.

Methods and apparatus for streaming data

There is provided a method of and apparatus for streaming data. Data segments containing audio and/or video data content are received over a network. The data segments are stored in a buffer. It is determined that the network has capacity to provide the content in the data segments at a higher quality than is currently stored in the buffer prior to playout of the data segments. A higher quality version of content of one or more data segments in the buffer that have the latest relative playout time are requested in preference to requesting a higher quality version of content of data segments that have earlier relative playout times.

Method of playing video, computing device, and computer program product

A method of playing video is provided. The method includes: obtaining a video loading instruction and sending a loading request to a cache server, wherein the loading request is configured to request loading data, and the loading data includes at least one segment of the video corresponding to the video loading instruction; receiving the loading data from the cache server; and playing the at least one segment according to the loading data.

Method, device, and computer program for transmitting media content

The invention relates to a method for transmitting from a server to a client, encoded media data corresponding to a projection of a wide view of a scene, the method comprising: Encapsulating the encoded data into tracks, Wherein information is provided for signaling that the client needs to parse other encoded data to display at least the encoded data encapsulated in a given track.

Providing files of variable sizes based on device and network conditions
11575949 · 2023-02-07 ·

Methods and systems for providing files of variable sizes based on device and/or network conditions are described herein. A computer device may convert a file into a first modified file that includes content of the file and a second modified file that includes the content of the file. The first modified file may have a first file size and be associated with a first bandwidth range. The second modified file may have a second file size different from the first file size and be associated with a second bandwidth range different from the first bandwidth range. Based on a bandwidth available to a user device, the first modified file or the second modified file may be provided for download by the user device.

Progressive increase in multimedia streaming quality

A computer-implemented includes streaming a first segment of multimedia data to a buffer on a first computing device at a first bitrate, wherein the first segment includes a first set of video frames encoded at a first resolution. The computer-implemented method further includes streaming a second segment of the multimedia data to the buffer on the first computing device at a second bitrate, wherein the second segment includes a second set of video frames encoded at a second resolution. The computer-implemented method further includes determining that a first predetermined threshold is reached. The computer-implemented method further includes streaming, in response to determining that the first predetermined threshold is reached, a third segment of multimedia data to the buffer on the first computing device, wherein the third segment includes a first set of pixels that are logically related to the second set of video frames of the second segment.

INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING SYSTEM, AND INFORMATION PROCESSING METHOD

An information processing device (10, 10A) includes a band requesting unit (162, 162A), an adjusting unit (164, 164A), and a transmitting unit (140). The band requesting unit (162, 162A) requests, according to a bandwidth necessary for transmitting information including a moving image, a use reservation of the bandwidth. The adjusting unit (164, 164A) adjusts, according to a result of the request by the band requesting unit and a reserved bandwidth, an information amount of information to be transmitted. The transmitting unit (140) converts the information with the adjusted information amount into a transmission signal and transmits the transmission signal.

System, Device, and Method for Enabling High-Quality Object-Aware Zoom-In for Videos
20220353435 · 2022-11-03 ·

System, device, and method for enabling high-quality content-aware zoom-in for videos. An input video is received at high resolution, and is processed. A first video stream is generated, being a downscaled lower-resolution version of the input video. One or more additional video streams are generated; each one of them being a cropped high-resolution version of the input video, such that the cropped region tracks an object-of-interest that is visually depicted in the input video. A multiple-streams manifest is generated, pointing to the first, downscaled, video stream, and also pointing to the one or more other, cropped high-resolution video stream. An end-user device plays the video, and enables the end-user to perform a high-quality zoom-in on the object-of-interest, by transitioning from playback of the downscaled video stream to playback of the additional video stream that tracks that object-of-interest.

Method and apparatus for selection of content from a stream of data

A main stream contains successive content elements of video and/or audio information that encode video and/or audio information at a first data rate. A computation circuit (144) computes main fingerprints from the successive content elements. A reference stream is received having a second data rate lower than the first data rate. The reference stream defines a sequence of the reference fingerprints. A comparator unit (144) compares the main fingerprints with the reference fingerprints. The main stream is monitored for the presence of inserted content elements between original content elements, where the original content elements have main fingerprints that match successive reference fingerprints and the inserted content elements have main fingerprints that do not match reference fingerprints. Rendering of inserted content elements to be skipped. In an embodiment when more than one content element matches only one is rendered. In another embodiment matching is used to control zapping to or from the main stream. In another embodiment matching is used to control linking of separately received mark-up information such as subtitles to points in the main stream.
