A streaming device may request and download multi-layer video segments based on a number of factors including the artistic interest associated with the video segments and/or the status of a buffer area managed by the streaming device. The multi-layer segments may be coded using scalable coding techniques or a combination of scalable coding and simulcast coding techniques by which each of the video segments may be coded into one or more representations of different qualities and/or bitrates. When requesting the multi-layer segments, the streaming device may ensure that the fullness of the buffer area falls between a buffer underflow threshold and a backfilling threshold under various network conditions. The streaming device may estimate the available network bandwidth in order to facilitate the scheduling decisions. The streaming device may consider the artistic interest associated with the video segments during scheduling and may give priority to those segments with higher artistic interest.

When a device is playing out a first media stream, the device determines a target time for beginning playout of a second media stream in place of the first media stream. The device then starts a stream-transition process that is expected to take anywhere from a minimum expected transition duration to a maximum expected transition duration, and the device starts the transition process in advance of the determined target time by the maximum expected transition duration, to help ensure timely starting of playout of the second media stream. Further, for an uncertainty period that extends from the minimum expected transition duration after the starting to the maximum expected transition duration after the starting, the device generates and plays a sequence of transition frames to help mask transition from the first media stream to the second media stream.

A method and device for communicating video for synchronization between a portable wearable camera and a wireless hub device are described. The portable wearable camera may capture first video data. Also, the portable wearable camera may transmit the first video data to the wireless hub device via a first wireless connection, and may capture second video data. When the first wireless connection between the wearable camera and the wireless hub device is unable to support full resolution video playback, the portable wearable camera may store the second video data. Further, the portable wearable camera may receive a request from the wireless hub device for the second video data via a second wireless connection, and may capture third video data. Further, the portable wearable camera may transmit, to the wireless hub device, the third video data via the first wireless connection and the second video data via the second wireless connection.

Methods and systems for saving resources when outputting a media asset such as a video are provided. The media asset is split into a first portion with a first importance and a second portion with the second importance. The first portion is displayed with a first set of output parameters (e.g., resolution, bit rate, frame rate, display size) and the second portion is displayed with a second set of output parameters that correspond to a lower quality than the first set of output parameters (e.g., a lower resolution, a lower bit rate, a lower frame rate, a lower display size).

The embodiment of the present disclosure provides a method and an apparatus for displaying a video image, an electronic device and a storage medium. The solution is as follows: receiving, by a server, a UDP request sent by a client based on an IP address of the server, wherein the UDP request includes identification information of a video to be played; acquiring the video to be played according to the identification information of the video to be played; encapsulating the video to be played from a key frame of the video to obtain a UDP packet; and sending the UDP packet to the client at a first transmission rate, so that the client, after receiving the UDP packet, decapsulates the UDP packet to obtain the video to be played, and display a first image frame of the video to be played, wherein the first transmission rate is the maximum transmission rate determined according to a network bandwidth. According to technical solutions provided in the embodiments of the present disclosure, the time required from initiating the request to displaying the first image frame of the video is reduced, and a display speed of the first image frame of the video is improved.
