Time shifted transcoded streaming (TSTS) system and method

摘要

A method and system for transmitting multimedia content from a server to a client device includes a source multimedia retriever to retrieve source multimedia content data. A transcoded multimedia retriever retrieves transcoded multimedia content data, the transcoded multimedia content data being a transcoded version of the source multimedia content, and the transcoded multimedia content data being time shifted with respect to the source multimedia content data. A data packet formulator formulates a data packet comprising the source multimedia content data and the time shifted transcoded multimedia content data. A data packet transmitter transmits the data packet from the server to the client device.
