System and method for multiple data channel transfer using a single data stream

摘要

A number of channels of data, including audio, image, text, and support data are collected at one or more centralized servers. The individual channels are edited and processed for content and format, including the deletion and insertion of advertising content and markers to indicate locations for additional content. These channels are then sent to a plurality of transmission servers for processing one or more of the channels including the insertion of content at designated markers and the combination of the channels of data into a single, packetized data transfer stream. The transmission servers broadcast the data transfer stream to a plurality of receiving units which de-packetize the original data channels and present any selected channel to the user of the receiving unit. The receiving units send status information back to the centralized servers where the data is processed and analyzed to evaluate the present and future use of advertisements.

主权项

1. A system for transferring a plurality of data sources using a single data transfer stream comprising:
a network operating center (NOC) including a centralized storage for said plurality of data sources; and an editing processor for editing said plurality of data sources; a communication link for transferring said edited plurality of data sources; a plurality of transmission servers communicated to the communication link; a packetizing and combining processor at each of said one or more transmission servers for cyclically packetizing and combining said plurality of data sources into a single data transfer stream; and, a plurality of receivers for receiving and processing said single data transfer stream communicated to the packetizing and combining processor in each one of the plurality of transmission servers, the plurality of receivers reversing the cyclic packetizing and combining performed in a corresponding one of the transmission servers, by select packets from a data package corresponding to a requested channel and reassembling these packets into the whole, original channel data enables fast channel switching in the corresponding receiver without any need to change a tuning or receiving frequency.
