In the case where image data of a super-high definition service is transmitted without scalable coding, image data suitable to own display capability in a receiver not supporting the super-high definition service can be easily obtained. A container in a predetermined format having a video stream including encoded image data is transmitted. Auxiliary information for downscaling a spatial and/or temporal resolution of the image data is inserted into the video stream. For example, the auxiliary information indicates a limit of accuracy for a motion vector included in the encoded image data. Further, for example, the auxiliary information identifies a picture to be selected at the time of downscaling the temporal resolution at a predetermined ratio.

The disclosed computer-implemented method may include receiving, as an input, segmented video scenes, where each video scene includes a specified length of video content. The method may further include scanning the video scenes to identify objects within the video scene and also determining a relative importance value for the identified objects. The relative importance value may include an indication of which objects are to be included in a cropped version of the video scene. The method may also include generating a video crop that is to be applied to the video scene such that the resulting cropped version of the video scene includes those identified objects that are to be included based on the relative importance value. The method may also include applying the generated video crop to the video scene to produce the cropped version of the video scene. Various other methods, systems, and computer-readable media are also disclosed.

A method or system configured for receiving a first single data stream representing a first multimedia file, the first single data stream including an interleaved sequence of data elements of a plurality of media, and/or transmitting a second single data stream representing a second multimedia file, the second single data stream including an interleaved sequence of data elements of said plurality of media, where the second multimedia file differs from said first multimedia file by at least one data element of a selected medium extracted from said first multimedia file, and/or by at least one data element of a selected medium added to the first multimedia file, and/or by at least one data element of a selected medium added to the first multimedia file being a converted version of the at least one data element of a selected medium extracted from the first multimedia file.

A method for managing the HTTP adaptive streaming of an item of digital content within a multimedia stream player terminal in a local communication network is disclosed, the multimedia stream player terminal being associated with a terminal for rendering the item of digital content. On detection of an active state of a screen saver mode of the rendering terminal, such a management method implements a progressive reduction of a video rendering quality of the streamed item of digital content, and maintains an audio rendering quality of the item of content.

A managed notification system compares image(s) and/or indicia relating to the image(s) and where there is a match selectively provides a notification of the same.

Systems and methods for implementing methods for cloud-based rendering of interactive augmented reality (AR) and/or virtual reality (VR) experiences. A client device may initiate execution of a content application on a server and provide information associated with the content application to the server. The client device may initialize, while awaiting a notification from the server, local systems associated with the content application and, upon receipt of the notification, provide, to the server, information associated with the local systems. Further, the client device may receive, from the server, data associated with the content application and render an AR/VR scene based on the received data. The data may be based, at least in part, on the information associated with the local system. The providing and receiving may be performed periodically, e.g., at a rate to sustain a comfortable viewing environment of the AR/VR scene by a user of the client device.

Provided is a bitstream processing method, including: acquiring auxiliary information in a bitstream, where the auxiliary information includes at least one of bitstream information for transcoding or bitstream information for supporting transcoding; and transcoding the bitstream by using the auxiliary information and generating a transcoded bitstream. Further provided are a bitstream processing device and a storage medium.

An information processing device includes a control unit that determines whether or not a terminal device and an imaging device are associated with each other on the basis of first identification information received from the terminal device and second identification information received from the imaging device, and sets the terminal device as a destination of transmission of a return video image on the basis of a determination result.

A method for performing live-streaming of user-generated content over a media-streaming network, including transmitting, by a 5.sup.th generation media streaming (5GMS)-aware application, a live-streaming request corresponding to the user-generated content to a 5GMS application provider (AP); receiving, by the 5GMS-aware application, from the 5GMS AP, an edge application server (LAS) profile corresponding to the live-streaming request, wherein the EAS profile indicates a service class (SC) from among a plurality of SCs, the SC corresponding to the live-streaming request; selecting, by the 5GMS-aware application, a 5GMS application server (AS) based on the SC; and performing the live-streaming of the user-generated content over 5GMS network to the 5GMS AS according to the SC.

A smart multimedia content receiver automatically resizes video images based on the content being displayed on the TV screen. Such a self-formatting content receiver includes on-board image processing capability that provides continuous video analysis to detect changes in program formatting and convert each frame as it is received in real time, as opposed to processing and re-releasing an entire program or movie, or relying on the viewer to re-format programs manually. In response to detecting a change, aspect ratio adjustments are made as needed. Because the self-formatting content receiver has access to the video data before it is displayed, such automatic on-the-fly adjustments ensure that the viewer's experience during program changes is seamless and without distortion. Subscribers can influence decisions made by the content receiver by pre-setting viewer preferences for aspect ratio adjustment.
