This technology enables prioritization of Multiple Stream Reservation Protocol (“MSRP”) transmissions in Audio Video Bridging (“AVB”) virtual local area networks (“VLANs”). An AVB switch receives a status from listener devices, associates a state with each of the statuses indicating whether each listener device is active or in-active, and stores each state in a database. For each listener device, a queue of MSRP protocol data unit (“PDU”) packets exists to be transmitted to the listener device. The AVB switch searches the database for listener devices with an active state, searches the queue for each active listener device for packets associated with an active state, and transmits the packets associated with the active state to each active listener device. Subsequently, the AVB switch searches each listener device's queue for packets associated with an in-active state and transmits the packets associated with an in-active state to each listener device.

A session management function receives, from a wireless device, a first message comprising delay information for offloaded processing of data for an application. The session management function sends, to the wireless device, based on the delay information, a second message comprising offloading information.

A system control apparatus for acquiring a prototype manifest file that is a basis of a manifest file to be transmitted to a viewing client in a system for delivering video data over a network, includes: an estimation unit configured to analyze content of a prototype manifest file acquired from an origin server, to determine a next acquisition timing of the prototype manifest file; and an acquisition unit configured to acquire the prototype manifest file from the origin server, based on the next acquisition timing determined by the estimation unit.

Methods and systems for early identification of bitrates for segments in adaptive bitrate streaming can allow the server to begin processing or transcoding content as necessary for delivery, reducing processing and transmission latency. In a first aspect, a client may request a second segment before the first segment has been completely received. The server may begin any transcoding processes for preparing the second segment, and once the server has completed sending the first segment, the server may begin transmitting the now-prepared or partially prepared second segment. The server can then transmit the first and second segment contiguously, with essentially no network dead time. In a second aspect, the client may transmit an early notification of parameters for the request of the second segment, allowing the server to begin transcoding. The client may subsequently request the already-prepared or partially prepared second segment, similarly reducing request-response processing latency.

The present disclosure relates to a video playback method and apparatus, a storage medium, and an electronic device. The method comprises: receiving a video playback request, the video playback request comprising first video information, and instructing to playback video data corresponding to the first video information by means of a target page; acquiring second video information corresponding to a video preview page, the video preview page being used to playback video data corresponding to the second video information; and when the first video information and the second video information are the same, performing video playback on the target page based on video playback progress information corresponding to the video preview page and video data loaded on the video preview page. Therefore, the transmission amount of video data can be effectively reduced, and the request response time of the video data and the waiting time of video playback can be shortened.
