Internet-Based Video Delivery System

Abstract

A system and method for delivering content over the Internet from a content source to a destination is disclosed which includes the use of an overlay network, built on an underlying IP network. Additionally, error correction capability is added to the overlay network to allow the destination to reconstitute packets lost during the transmission over the Internet. In one embodiment, an overlay network is created using a plurality of overlay nodes, which may be geographically distributed. Each respective content source or destination is also a part of the overlay network. Overhead, capable of providing error correction capability, is added to the content flow as it enters the overlay network. As the content flow leaves the overlay network, this overhead is removed from the content flow. In the case of transmission errors across the overlay network, the overhead information is used to reconstitute lost or corrupted packets.

Description

[0001]This application claims priority of U.S. Provisional Patent Application Ser. No. 61 / 728,012, filed Nov. 19, 2012, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The flood of news, financial, political and other informational television programs has generated an ever increasing demand to utilize on-air experts, such as investment bankers, lawyers, and politicians. The presence of these experts adds credibility and an in-depth analysis of a given topic that is not otherwise possible.[0003]Traditionally, for this interview to occur, the expert is forced to travel to the television studio of the television show that is interested in interviewing this expert. This involves costs for the television program, and an inconvenience for the expert. For example, the expert would have to travel to the studio, where they are prepared for the interview through hair and makeup, and appear on camera. They then travel back to their o...

AI Technical Summary

Benefits of technology

The present invention is a system and method for delivering content over the Internet from a content source to a destination. It uses an overlay network built on the underlying IP network and adds error correction capability to reconstruct lost packets during transmission. The system includes multiple overlay nodes distributed throughout the country or world, with each content source or destination being a part of the overlay network. Overhead, capable of providing error correction capability, is added to the content flow as it enters the overlay network and removed from the content flow as it leaves the network. This invention helps to improve the reliability and accuracy of content delivery over the Internet.

Problems solved by technology

This involves costs for the television program, and an inconvenience for the expert.

In addition, such an arrangement does not allow for real-time analysis of time-sensitive events, such as breaking news, corporate mergers, or political reaction, as the experts need time and sufficient notice to travel to the studio.

The communication infrastructure required to transmit the video feed from the remote studio to the control location may be expensive.

The fiber-based long distance transmission model involves a high installation cost, high monthly recurring cost and modest per-usage cost.

In addition, such equipment may only be able to control one camera at a time.
