VIDEO PROCESSING METHOD AND APPARATUS, TERMINAL, AND STORAGE MEDIUM

In a video processing method, a video reverse playback instruction is received. A total video duration of the video and a played duration of the video are obtained in response to the video reverse playback instruction. The video reverse playback instruction indicates that the video is to be played in reverse order. A first reverse playback time point corresponding to the video is determined according to the total video duration and the played duration. Subdata from video data of the video is determined based on a time range indicated by the first reverse playback time point and a pre-loading time threshold. The subdata corresponds to the time range of the video. The subdata is pre-loaded to obtain pre-loaded video data. Further, a first reverse playback video frame corresponding to the first reverse playback time point is obtained from the pre-loaded video data for playback in the reverse order.

20210099754 · 2021-04-01 ·

A method and an apparatus for transmitting video-based point cloud contents (VPCC) data by a server are provided. The method includes generating moving picture experts group (MPEG) media transport protocol (MMTP) packets including at least one asset for the VPCC data, generating a signaling message including an asset group message about the at least one asset, and transmitting the MMTP packets and the signaling message to a client.

Synchronizing and dynamic chaining of a transport layer network service for live content broadcasting

Aspects of the subject disclosure may include, for example, a processing system of a communication node routing data packets for a first streaming session between a viewer node of a plurality of viewer nodes and a content streaming server through the communication node without interrupting delivery of content data to the viewer node, establishing a second streaming session with the content streaming server to receive the content data, creating a first and second replacement connections by imitating a connections with the content streaming server and the viewer node, receiving a control packet over the second streaming session from the content streaming server, and splitting the first streaming session responsive to receiving the control packet. Other embodiments are disclosed.

Method and system of push-template and URL list for dash on full-duplex protocols
10820025 · 2020-10-27 · ·

A method and system of message exchange for controlling flow associated with multimedia streaming services from a server to a client using DASH are disclosed. In one method, one or more Push Directives are sent from a client to a server to indicate information related to media data requested. At least one selected Push Directive uses one URLTemplate that comprises a list of media parameter values, and where each media parameter value corresponds to one media parameter associated with one media segment requested. The server then pushes one or more groups of data for the media data requested to the client according to the list of media parameter values. In another method, at least one selected Push Directive uses one URLTemplate that includes a first number to represent a number of repeating difference of media parameter values associated with requested media segments.

MULTIPATH POLICY DECISIONS FOR ENCRYPTED VIDEO STREAMS

The invention relates to a method, for controlling at least one path in a multipath environment by a path control entity, wherein the at least one one path is used for transmitting an encrypted video stream comprising a sequence of video segments. The method comprises the following steps: estimating a resolution used in the video stream based on the video segments, and determining that the resolution used in the video stream has changed during the transmission. When it is determined that the resolution used in the video stream has changed, an adaptation of a number of the at least one path used for transmitting the video stream in the multipath configuration is initiated based on the determined change of the resolution.

Remote engagement system
10555047 · 2020-02-04 ·

A remote engagement system for a live event includes at least one output device located at the live event for providing an audio and/or visual output to people at the live event. A controller receives signals transmitted from a plurality of user input devices and in response thereto and in real time or near real time, controls the at least one output device located at the live event to provide an audio and/or visual output to people at the live event.

Media-aware radio access network packet scheduling

A processor of a base station of a radio access network may receive a plurality of parameters for a media streaming session for a transmission of a media to an endpoint device, select at least one radio access network resource for the media streaming session based upon the plurality of parameters for the media streaming session, and establish the media streaming session in accordance with the at least one radio access network resource. The plurality of parameters may comprise a type of media parameter, a packet size parameter, and a mobility parameter. The at least one radio access network resource may comprise a number of carriers, a transmission time interval, a number of sub-carriers, a modulation coding scheme, a carrier frequency, or a duration of a reservation.

SYNCHRONIZING AND DYNAMIC CHAINING OF A TRANSPORT LAYER NETWORK SERVICE FOR LIVE CONTENT BROADCASTING

Aspects of the subject disclosure may include, for example, a processing system of a communication node routing data packets for a first streaming session between a viewer node of a plurality of viewer nodes and a content streaming server through the communication node without interrupting delivery of content data to the viewer node, establishing a second streaming session with the content streaming server to receive the content data, creating a first and second replacement connections by imitating a connections with the content streaming server and the viewer node, receiving a control packet over the second streaming session from the content streaming server, and splitting the first streaming session responsive to receiving the control packet. Other embodiments are disclosed.

Systems and methods for correlating multiple TCP sessions for a video transfer

User equipments can download a video file by instantiating multiple video requests, each request specifying different parts of the video file. If each video request initiates a separate transmission control protocol (TCP) session, which is the case with an hypertext transfer protocol (HTTP) partial get request, then a network device in a communications network would be oblivious of contextual information, which indicates that the TCP sessions download different portions of the same video file. This disclosure provides systems and methods for correlating multiple TCP sessions so that a network device in a communications network can be aware of the contextual information.

METHOD AND SYSTEM FOR INTEGRATED STACKING FOR HANDLING CHANNEL STACKING OR BAND STACKING
20190158200 · 2019-05-23 ·

Methods and systems are provided for integrated channel and/or band stacking solutions. A plurality of signals may be received, such as via a signal receiver, with each of the received signals being different from remaining ones of the plurality signals. At least two received signals may be processed, such as via one or more processing circuits, and an output signal may be generated based on the processing of the at least two received signals. The output signal may include only one or more portions from each of the at least two signals, with the one or more portions being stacked within the output signal.
