Transaction system for transporting media files from content provider sources to home entertainment devices

Abstract

A system and method for enabling a user to request and download selected media files from distributed content provider sites via the Internet. The system includes a plurality of user sites each including a player / receiver housed in an enclosure having a simple user interface, a plurality of content provider sites, and a transaction server site. The player / receiver enables the user to connect to the transaction server via the Internet to access a program guide listing available media files. The user is then able to select a desired file and, via the player / receiver and Internet, request the transaction server to authorize download of the selected file. The file request along with file encryption and transfer instructions are sent from the transaction server via the Internet to the content provider site storing the requested file. Requested files are then dynamically encrypted by the content provider site and securely downloaded to the requesting player / receiver. The requesting player / receiver is uniquely capable of decrypting a downloaded file concurrent with playing back the file on a conventional home television set and / or audio system.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to systems for delivering digital media files (e.g., audio and / or video) from content provider sites to home user entertainment systems (e.g., television sets and / or audio equipment) via communications networks including public networks, e.g. Internet, and private networks, e.g., intranet and extranet. [0002] Existing systems for transferring media files to the home user are typically complex, expensive to implement and maintain, lack sufficient security and flexibility, do not effectively utilize existing home entertainment infrastructure, and do not effectively leverage the open architecture of the Internet and standard communications protocols or encryption technologies. Generally, the limitations of not existing systems can be attributed to attempts to force a broadcast model onto communications network architectures that are designed to store and forward data as packets, rather than as continuous streams. [0003] For exam...

Problems solved by technology

Existing systems for transferring media files to the home user are typically complex, expensive to implement and maintain, lack sufficient security and flexibility, do not effectively utilize existing home entertainment infrastructure, and do not effectively leverage the open architecture of the Internet and standard communications protocols or encryption technologies.

Generally, the limitations of not existing systems can be attributed to attempts to force a broadcast model onto communications network architectures that are designed to store and forward data as packets, rather than as continuous streams.

For example, so called “video on demand” systems deliver only video files for viewing and the infrastructure to enable transfer of those files to the home user is highly capital intensive.

Moreover, such systems are typically difficult to scale since at any point in time, a unique stream must be dedicated to a particular user, from the video server to the users set top box.

Further, video on demand systems typically do not have the capability to access and transfer media files that reside on networks outside of the proprietary networks operated by the particular video on demand operator.

This limits the number of titles that can be offered.

These terminals require the home user to purchase and learn to use a special purpose device that does not leverage the user's current investment in home entertainment and communications infrastructure.

Further, these devices do not facilitate effective storage and playback of media files downloaded from the Internet since they do not typically interface to conventional television sets or audio systems for viewing and listening, respectively.

Other prior art involving streaming media via communications networks does not address the home user's need to select and acquire media files from the Internet, for example, without having to dedicate a computer to the task.

Specifically, prior art associated with streaming media from the Internet to computers does not address the need to store and play back the streamed media at user selectable times via existing home entertainment systems that are already familiar to the home user.
