摘要

The present disclosure relates to methods and systems for progressively delivering multimedia content over a network. According to one aspect, a system for delivering multimedia content through a network includes a server side sub-system and a client side sub-system. The server side sub-system is configured to: concurrently send a first predetermined portion of each of the plurality of objects through the network, wherein the first predetermined portion is less than a complete object for at least one of the plurality of objects; and after sending the first predetermined portion of each of the plurality of objects, successively send subsequent predetermined portions of each of the plurality of objects until all portions of the plurality of objects have been sent. The client side sub-system is configured to: receive the first predetermined portion of each of the plurality of objects through the network; and after receiving the first predetermined portion of each of the plurality of objects, successively receive subsequent predetermined portions of each of the plurality of objects until all portions of each of the plurality of objects have been received.
