SERVER-SIDE SCHEDULING FOR MEDIA TRANSMISSIONS

摘要

A server that incorporates the subject disclosure may perform, for example, operations including monitoring current transport characteristics of an internet protocol network communicatively coupled to the server and to a mobile device. Data packets are transported to the device according to a dynamic adaptive streaming over hypertext transfer protocol. A future transport characteristic of the network is predicted according to the trajectory of the device. A request is received from the device for transmission of a data packet, and a time for fulfilling the request is scheduled according to the current and predicted transport characteristics. The operations further comprise selecting a transmission rate for transmission of the data packet to the mobile device responsive to detecting the time for fulfilling the request. The device performs buffering of the data packet for a future presentation of the media content. Other embodiments are disclosed.

主权项

1. A device comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
monitoring transport characteristics of a network communicatively coupled to the device to determine a first network throughput associated with a current location of the device, wherein data packets representing media content are transported by the network to the device according to an adaptive streaming protocol;predicting a future location of the device, based on a current location of the device, a history of movement of the device, a trajectory of the device, or a combination thereof;predicting a second network throughput in accordance with the predicted future location;scheduling a request to a server for transmission of data packets corresponding to a segment of media content over the network, in accordance with the second network throughput;receiving the data packets corresponding to the segment of media content from the server in fulfillment of the request; andresponsive to the second network throughput being less than the first network throughput:
requesting transmission of additional data packets from the server; andbuffering the additional data packets to avoid a degradation in a viewing quality of media content in a future presentation by the device.
