Method and Device for Live Video Broadcast
A method and device for live video broadcast is disclosed. The method includes: acquiring first live broadcast configuration information corresponding to a first process, and live broadcasting video streaming corresponding to the first process according to the first live broadcast configuration information; when it is detected that a running state of a second process is an activated state, acquiring second live broadcast configuration information corresponding to the second process, and detecting a relationship between the first process and the second process according to the first live broadcast configuration information and the second live broadcast configuration information; and when it is detected that the relationship between the first process and the second process is an association relationship, switching the live broadcasted video streaming corresponding to the first process for video streaming corresponding to the second process according to the second live broadcast configuration information.
SYSTEMS, METHODS, AND DEVICES FOR OPTIMIZING STREAMING BITRATE BASED ON VARIATIONS IN PROCESSOR LOAD
Systems, methods, and devices are provided for optimizing streaming bitrate in response to variations in processor load. In various embodiments, a streaming media server includes a processor and a computer-readable storage medium, which stores computer-readable code or instructions. When executed by the processor, the computer-readable code causes the server to encode segments of a video stream at a final variable bitrate (ABR.sub.FINAL). The encoded segments are transmitted from the server, over a network, and to a first client media receiver for presentation to an end-user. The steps of encoding and transmitting are repeated during a streaming video session with the first client media receiver, while varying a value of ABR.sub.FINAL based, at least in part, upon a running average of a processor load placed on the processor (LOAD.sub.AVG).
GLOBAL APPROACH TO BUFFERING MEDIA CONTENT
In various embodiments, a graph streaming application computes a first distance along a first potential playback path between a first playback position and a first media content block. The graph streaming application then computes a first score for the first media content block based on the first distance and a first probability associated with the first potential playback path. Similarly, the graph streaming application computes a second score for a second media content block based on a second playback position, a second potential playback path, and a second probability associated with the second potential playback path. The graph streaming application compares the first score and the second score to determine that the first media content block should be buffered by a client device. The graph streaming application then causes the first media content block to be stored in a playback buffer for subsequent playback on the client device.
DYNAMIC CLIENT BUFFERING AND USAGE OF RECEIVED VIDEO FRAMES FOR CLOUD GAMING
A method is disclosed including setting, at a server, a server VSYNC signal to a server VSYNC frequency defining a plurality of frame periods. The server VSYNC signal corresponding to generation of a plurality of video frames at the server during the plurality of frame periods. The method including setting, at a client, a client VSYNC signal to a client VSYNC frequency. The method including sending a plurality of compressed video frames based on the plurality of video frames from the server to the client over a network using the server VSYNC signal. The method including decoding and displaying, at the client, the plurality of compressed video frames. The method including analyzing the timing of one or more client operations to set the amount of frame buffering used by the client, as the client receives the plurality of compressed video frames.

Low latency streaming media
Methods and systems for discovering or tuning-in to near live or current playlists used to stream media content, particularly for live events during which the media content is streamed. The methods and systems can reduce the time required to tune-in to such live events. In one embodiment, a client device can receive an age data in a header of a message that returns a first playlist that was requested by an unattributed playlist request from the client device. The age data can be used to determine how many partial media segments to skip to tune-in to the live event.
Pre-fetch of data using seek intervals
A data storage device comprises a non-volatile memory, a buffer, and a controller. The controller is configured to decode a media file to extract timestamp information related to a set of frames of the media file and receive, from a host, a seek command associated with playback of the media file. The seek command includes a seek interval. The controller is further configured to remove at least a portion of the set of frames based at least in part on the seek interval and the extracted timestamp information and transmit a subset of the set of frames, not including the removed at least a portion of the set of frames, to the host.
AUTOMATED RESOURCE MANAGEMENT FOR DISTRIBUTED COMPUTING
In some embodiments, infrastructure data and service data is received for a computing infrastructure. The infrastructure data indicates resources in the computing infrastructure, and the service data indicates services to be orchestrated across the computing infrastructure. An infrastructure capacity model is generated, which indicates a capacity of the computing infrastructure over a particular time window. Service-to-resource placement options are also identified, which indicate possible placements of the services across the resources over the particular time window. Resource inventory data is obtained, which indicates an inventory of resources that are available to add to the computing infrastructure during the particular time window. An infrastructure capacity plan is then generated, which indicates resource capacity allocation options over the time slots of the particular time window. Resource capacities for the services are then allocated in the computing infrastructure.
DOWNLOAD CONTROL IN MULTI-SERVER COMMUNICATION SYSTEM
Apparatuses and methods for data traffic management in multi-source content delivery are described. The apparatus includes a downloader and a controller. The downloader is coupled to servers via communication links. The controller is configured to determine initial download requests for the servers based on predetermined information about a quality of the links. The controller is also configured to send the initial download requests to the servers with the downloader. The controller is further configured to update the information about the quality of the communication links after the downloader receives data associated with a data file from the servers via the communication links. The controller is also configured to determine subsequent download requests for the servers based on the updated information about the quality of the communication links. The controller of further configured to send the subsequent download requests to the servers via the downloader. Rate adaptation is also proposed for each server, and download termination requests are transmitted to the servers when the download is almost complete at the apparatus.
