Media network using set-top boxes as nodes
First Claim
1. A method, comprising:
- communicatively coupling a set-top box with a hub of a media network, wherein the set-top box receives streaming Moving Picture Experts Group video modulated on coaxial cable rather than over an Internet protocol-based local area network;
filtering signals received by the media network to provide one or more available frequencies for communication between the set-top box and the hub;
tuning the set-top box to send data to the hub on an out-of-band channel; and
tuning the set-top box to receive data from the hub on an in-band channel.

Abstract
Subject matter includes methods of using conventional set-top boxes that receive streaming video modulated on coaxial cable rather than over an IP-based LAN as nodes in a media network. In one implementation, an exemplary adapter is used to integrate a conventional set-top box into a media network. In one implementation, an exemplary filter is used to reserve frequencies for communications between a conventional set-top box and a hub and to prevent communications from leaving a media network. In one implementation, an exemplary content protection method provides a way of encrypting program content on the media network in a manner that a conventional set-top box can decode.

14. A system, comprising:
-
a computing hub for receiving and storing multimedia content;
a set-top box coupled with the computing hub, wherein the set-top box receives streaming Moving Picture Experts Group video modulated on coaxial cable rather than over an Internet protocol-based local area network and wherein the set-top box sends data to the hub on an out-of-band channel and receives data from the hub on an in-band channel. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. An electronic filter, comprising:
-
an incoming filter to produce a band of blocked frequencies in an incoming stream of multimedia signals, wherein the incoming filter blocks signals having one of the blocked frequencies from entering a media network from a multimedia headend; and
an outgoing filter to block signals that originate in the media network and have one of the blocked frequencies from leaving the media network. - View Dependent Claims (34)

35. An adapter, comprising:
-
a tuner to tune an out-of-band channel of a set-top box to a frequency selected for communication over a media network, wherein the media network has a hub that communicates over an Internet Protocol-based local area network with one or more network media nodes and communicates over the out-of-band channel and the in-band channel with the set-top box and one or more other set-top boxes;
a quadrature phase shift keying (QPSK) demodulator coupled with the tuner to demodulate upstream data signals from the tuner to the hub;
a quadrature amplitude modulation (QAM) modulator to receive and modulate data and multimedia content from the hub; and
an upconverter coupled with the quadrature amplitude modulation (QAM) modulator to upconvert modulated data and multimedia content signals to the set-top box. - View Dependent Claims (36, 37, 38, 39)
