REDISTRIBUTING SOURCES FOR ADAPTIVE BIT RATE STREAMING

摘要

A system includes one or more network media service devices, with each network media node operably connected upstream to one or more gateway devices. At least one of the network media service devices is configured to intercept an ABR-related request to receive digital media content for a media channel sent from a client set top box to a remote ABR server located upstream from the at least one network media device, identify a second gateway device that is storing the digital media content, the second gateway device having previously received the digital media content from the remote ABR server, and return a network address of the second gateway device to the client set top box for use by the client set top box to receive the digital media content from the second gateway device. In various implementations, the network address is returned in connection with an HTTP response indicating a redirection to the network address.

主权项

1. A method for identifying media resources for providing adaptive bit rate (ABR) streaming to client devices, comprising:
intercepting an ABR-related request to receive digital media content for a media channel sent to a remote ABR server from a client device, the request being sent through a first gateway device; determining that a second gateway device is storing the digital media content requested by the client device, the second gateway device having previously received the digital media content from the remote ABR server; and returning a network address of the second gateway device to the client device for use by the client device to receive the digital media content from the second gateway device; wherein the first and second gateway devices are operably connected such that a request to receive the stored digital media content from the second gateway device that is sent through the first gateway device is routed to the second gateway device.
