Processing encoded content

摘要

A system and method for the management of client computing device content requests by service providers are provided. The requested content corresponds to content organized as a series of ordered frames, which include a number of reference frames. The management of the content requests can include the selection of computing devices corresponding to various Point of Presence locations for providing requested content. The selection of the computing devices can incorporate logic related to the delivery of a first subset of the content from a Point of Presence based on minimizing delivery latencies. The selection of the computing devices can incorporate logic related to the delivery of a second subset of the content from a second Point of Presence based on minimizing costs associated with delivery of the second subset.

1. A method for request routing comprising:
obtaining, by a first Point of Presence, a request corresponding to encoded content, the encoded content defined by a series of ordered frames including a number of reference frames within the encoded content; transmitting, by the first Point of Presence, a subset of frames less than the encoded content, the subset of frames including one or more reference frames; obtaining, by a second Point of Presence, a second request corresponding to the encoded content, the request corresponding to a second subset of the encoded content including at least some portion of the ordered frames of the encoded content not previously included in the subset of frames transmitted by the first Point of Presence; determining, by the second Point of Presence, a transmitting order for the sequentially ordered frames included in the second subset, the transmitting order different from an order corresponding to the sequence of frames and determined, at least in part, on historical information used to prioritize at least a portion of the ordered frames estimated to be required during rendering; and transmitting, by the second Point of Presence, the second subset of the encoded content.
