Strategies for Integrating Plural Modes of Content Delivery
First Claim
1. A system for receiving and processing media content, comprising:
- a format converter configured to;
receive broadcast media content from a broadcast delivery infrastructure;
convert the broadcast media content into an Internet Protocol (IP) format; and
apply digital rights management protection to the broadcast media content,the format converter thereby providing rights-protected media content expressed in the IP format;
a network interface device for receiving on-demand media content from an IP delivery infrastructure, the on-demand media content being expressed in the IP format;
an IP processing device configured to receive and process an output signal generated by the format converter and an output signal generated by the network interface device.

Abstract
A hybrid system is described which allows an Internet Protocol (IP) set-top box to receive broadcast media content from a broadcast delivery infrastructure and on-demand media content from an IP delivery infrastructure. The broadcast delivery infrastructure can generate a quadrature amplitude modulated (QAM) signal, while the IP delivery infrastructure can generate an IP-based signal. The system uses a format converter to convert the QAM signal into a rights-protected signal expressed in an IP-compatible format. The format converter can be implemented as an OpenCable Unidirectional Receiver (OCUR) device.

12. A method for receiving and processing media content, comprising:
-
receiving broadcast media content from a broadcast delivery infrastructure; converting the broadcast media content into an Internet Protocol (IP) format and applying digital rights management protection to the broadcast media content, to thereby provide a first IP format output signal; receiving on-demand media content from an IP delivery infrastructure, the on-demand media content being expressed in the IP format, to thereby provide a second IP format signal; and supplying the first IP format output signal and the second IP format output signal to an IP processing device for processing. - View Dependent Claims (13, 14, 15, 16, 17)

18. A system for receiving media content, comprising:
-
a first delivery infrastructure for delivering quadrature amplitude modulated (QAM) broadcast media content; a format converter configured to; receive the QAM broadcast media content over the first delivery infrastructure; convert the QAM broadcast media content into an Internet Protocol (IP) format; and apply digital rights management protection to the QAM broadcast media content, the format converter thereby providing rights-protected media content expressed in the IP format; a second delivery infrastructure for delivering on-demand media content expressed in the IP format; a network interface device for receiving the on-demand IP media content over the second delivery infrastructure; an IP processing device configured to receive and process an output signal generated by the format converter and an output signal generated by the network interface device. - View Dependent Claims (19, 20)
