Aspects of the subject disclosure may include, for example, a method in which a processing system obtains encoded video content, and transmits the encoded video content over a network for presentation at a communication device by a video player executing on the communication device. The encoded video content is decoded in a decoding process by a decoder of an operating system of the communication device to generate decoded video content; the decoded video content is analyzed by a complexity analyzer of the operating system to generate a video complexity report. The method also includes receiving the video complexity report over the network from the communication device, and adjusting a data rate for the encoded video content, based at least in part on the video complexity report, to generate adjusted video content for transmission to the communication device. Other embodiments are disclosed.

A transmission device encodes content data, divides the encoded content data into a plurality of pieces of transmission data, and transmits the pieces to, through a plurality of uploaders and a plurality of networks corresponding to the plurality of uploaders, a distribution device configured to perform content distribution.

The disclosed computer-implemented method may include receiving original media content, transcoding the original media content into a plurality of encoded media files, determining an adaptive bit rate for providing a one of the plurality of encoded media files to a computing device, delivering the encoded media file to the computing device at the adaptive bit rate for viewing on a display device of the computing device, and measuring a quality of the displayed encoded media file based on an overall mean opinion score associated with the delivered encoded media file. The overall mean opinion score may be based on a measured playback quality associated with the encoded media file and a measured upload quality associated with the original media content. Various other methods, systems, and computer-readable media are also disclosed.

Methods and systems for improved quality of a streaming session using multiple simultaneous streams. For the multiple simultaneous streams an audio/video device (A/V device) records and generates a high-resolution stream and a low-resolution stream for simultaneous transmission to a server. The server selects one of the two streams for retransmission to a destination client device. The server also monitors the streaming session and estimates a total available bandwidth between the server and the A/V device and assigns a confidence value to the bandwidth estimation. The server periodically transmits the bandwidth estimate and confidence value to the A/V device to improve the efficiency of the streams being generated by the A/V device. The A/V device can use the received bandwidth estimate and confidence value to adapt the resolution of each of the streams to efficiently use the total available bandwidth between the A/V device and the server.

A client receives streaming data according to Moving Picture Experts Group-Dynamic Adaptive Streaming over HTTP (MPEG-DASH) standard. The client includes a transmitter which transmits a Media Presentation Description (MPD) request or a segment request to a server, and a receiver which receives an MPD specified in the MPD request and a segment specified in the segment request. The MPD request contains information requesting transmission of an initialization segment by a push. The receiver receives the initialization segment transmitted by the push.

In various embodiments, a subsequence-based encoding application generates subsequences based on a source sequence associated with a media title. The subsequence-based encoding application then encodes both a first subsequence and a second subsequence across each of multiple configured encoders and at least one rate control value to generate, respectively, a first set of encoded subsequences and a second set of encoded subsequences. Notably, each configured encoder is associated with a combination of an encoder and a configuration, and at least two configured encoders are different from one another. Subsequently, the subsequence-based encoding application generates encoded media sequences based on the first set of encoded subsequences and the second set of encoded subsequences. Finally, the application selects a first encoded media sequence from the encoded media sequences based on a first target value for a media metric to subsequently stream to a first endpoint device during playback of the media title.

Techniques are described for streaming (e.g., low-latency streaming) of media content by performing sender-based adaptive bit rate control operations. The operations can include streaming a media stream to a streaming client. While streaming the media stream, an outgoing queue of buffered streaming content to be sent to the streaming client can be monitored. When a step down condition is satisfied, based at least in part on the monitoring, a switch can be made to a lower bit rate media stream for streaming to the streaming client. When a step up condition is satisfied, based at least in part on the monitoring, a switch can be made to a higher bit rate media stream for streaming to the streaming client. The operations are performed without receiving any quality feedback from the streaming client and without measuring bandwidth of the network channel.

A method of supporting Adaptive Bit Rate, ABR, video resolution shaping of a video data stream of a video session transferred by a User Plane Function, UPF, in a Service Based Architecture, SBA, domain. The video resolution shaping is performed by the UPF implementing a Reinforcement Learning Agent, RLA, operating with an observation space having a determined video resolution of a received video data stream, a reward space having a reward referring to a required video resolution, and an action space having video resolution shaping levels to be applied at the received video data stream. Complementary methods and devices for performing such a method in an SBA domain deployed in a telecommunications system are disclosed.

Described embodiments include a system that includes a network interface and a processor. The processor is configured to identify, via the network interface, a state of congestion in a communication channel between a base station belonging to a cellular network and a client device, to calculate, responsively to the state of congestion, a maximum sustainable encoding bit rate (MSEBR) for a video that is being downloaded by the client device, from a server, via the communication channel, the video being encoded at a plurality of different predefined bit rates, and to inhibit the client device, in response to calculating the MSEBR, from downloading a segment of the video that is encoded at any one of the predefined bit rates that exceeds the MSEBR. Other embodiments are also described.
