Intrasegment Adjustment of Video Transmission Rate

A method includes determining a first transmission rate for transmitting an entirety of a segment of a video stream to a client device. The segment includes a set of frames. In some implementations, the method includes, after transmitting a first subset of the set of frames at the first transmission rate, detecting that a network connectivity of the client device has reduced below a connectivity threshold associated with the first transmission rate. In some implementations, the method includes transmitting an entirety of the segment at a second transmission rate that is less than the first transmission rate. In some implementations, the method includes triggering the client device to present a second subset of the set of frames that corresponds to a temporal position in the video stream after the first subset of the set of frames while foregoing re-presentation of the first subset of the set of frames.

A method and system for managing adaptive bitrate video streaming. The method including: retrieving raw data associated with a video stream traffic flow; determining at least one video chunk from the raw data of video stream traffic flow; determining parameters associated with the video chunk; determining a bitrate factor based on the parameters; determining a Quality of Experience (QoE) score based on the bitrate factor; and providing a traffic action based on the QoE score. The system including: an input module configured to retrieve raw data; an analysis module configured to determine at least one video chunk from the raw data and determine parameters associated with the video chunk and a bitrate factor based on the parameters; a QoE module configured to determine a QoE score based on the bitrate factor; and an output module configured to provide a traffic action based on the QoE score.

Optimized delivery techniques

Methods are described for managing the delivery of electronic data, such as media content, through a network. An indication of a quantity of data transmitted via a network during a first time period may be received, the quantity of data including a first portion of a content item. Based on the quantity of data transmitted during the first time period, it may be determined that a first bandwidth utilization threshold of the network has been satisfied, and the network may be optimized for delivery of a second portion of the content item.

Method for transmitting multimedia resource and terminal

A method for transmitting a multimedia resource, including: determining target address information based on a media presentation description of a multimedia resource, where the media presentation description includes address information of the multimedia resource having different code rates, and the target address information is address information of the multimedia resource having a target code rate; and sending a frame acquiring request carrying the target address information to a server, where the frame acquiring request is configured to instruct the server to return media frames of the multimedia resource at the target code rate.

Method and system for processing multimedia content within a metropolitan area network
11523147 · 2022-12-06 · ·

A method for processing a multimedia content previously digitally encoded into an audio-video stream and transmitted from a distribution platform for the purposes of on-demand transmission to a plurality of receiving terminals includes the following steps: applying a demultiplexing function to the audio-video stream, said function being arranged to generate at least one group of data streams; applying a transformation to each data stream; segmenting each data stream; storing the at least one group of segmented data streams in a memory; carrying out, only in response to a request issued by a receiving terminal among the plurality of receiving terminals, the following steps: selecting, on the basis of the request, at least one data stream of at least one group of stored data streams; and transmitting the at least one selected data stream to the receiving terminal that issued the request.

Systems and methods for adjusting a congestion window value of a content delivery network
11595311 · 2023-02-28 · ·

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for controlling a congestion window (CWND) value of a communication session of a CDN. In particular, a content server may analyze a request to determine or receive an indication of the type of content being requested. The content server may then set the initial CWND based on the type of content being requested. For example, the content server may set a relatively high CWND value for requested content that is not particularly large, such as image files or text, so that the data of the content is received at the client device quickly. For larger files or files that a have a determined smaller urgency, the initial CWND may be set at a lower value to ensure that providing the data of the content does not congest the link between the devices.

Net-aware service to control media distribution node output

A method includes receiving a first control command including a value for a first control parameter. The method further includes determining an association between the first control command and an identifier of the first control parameter. The method also includes identifying a graphical user interface (GUI) tool and information of the GUI tool based on the identifier of the first control parameter. The method includes launching a GUI that includes the GUI tool. The method further includes updating the first control parameter using the GUI tool based on the information of the GUI tool and the value for the first control parameter. The method also includes initiating content streaming using a first modulator in response to updating the first control parameter. The method includes identifying performance data for the first modulator associated with the content streaming. The method further includes sending the performance data to a server via the network.

Method of playing video, computing device, and computer program product

A method of playing video is provided. The method includes: obtaining a video loading instruction and sending a loading request to a cache server, wherein the loading request is configured to request loading data, and the loading data includes at least one segment of the video corresponding to the video loading instruction; receiving the loading data from the cache server; and playing the at least one segment according to the loading data.

GLOBAL CONSTRAINT-BASED CONTENT DELIVERY NETWORK (CDN) SELECTION IN A VIDEO STREAMING SYSTEM

In some embodiments, a method receives a request for a video and receives a ranking of content delivery networks for the request. Also, global constraints are received for the content delivery networks. The global constraints define an allocation for respective content delivery networks. The method selects a content delivery network using the global constraints and the ranking. A score for the content delivery network is altered from a first score to a second score in the ranking and used in the selecting of the content delivery network. The content delivery network that is selected for the request is outputted.
