DETAILED DESCRIPTION OF THE INVENTION
The present invention permits the integration of one or more communication network with one or more media-delivery network. One result of the integration is the ability to deliver communication services over the media-delivery network to a host device. While the type of communication network described in detail herein is a telecommunication network, and, more particularly, a mobile telecommunication network, one skilled in the art will appreciate that the present invention may be implemented with other types of communication networks permitting the multi-directional exchange of information (in any format, including analogue). Likewise, one skilled in the art will appreciate that while cable television networks are described herein as an example of a media-delivery network, the present invention may be implemented with other types of media delivery networks that permit the substantially uni-directional delivery of media content.
Telephone services provided via a mobile telephone may be delivered to a cable host device in accordance with an embodiment of the present invention. A telephone network that provides telephone services is usually owned by a telephone carrier and is separate from a cable network that provides cable-television programming and is owned by a cable operator.
The present invention may deliver communication services associated with a communication network, such as a mobile telephone network, to a media-delivery network, such as digital cable television, by interfacing the two networks, for example at a cable head end, and delivering services over the media-delivery network. In the example of digital cable television services may be delivered on the unbound signaling channel typically employed in a digital cable television network or on one or more bound digital cable channels. In accordance with the present invention, services may be delivered on any type of bound digital channel, including a premium channel, a pay-per-view channel, a regular channel, or an unbound channel used to deliver programming information.
In a digital cable television network, content is delivered on multiple bound channels, and a user selects content by selecting at the cable host device the channel on which the desired content is available. The cable host device then displays the content on the desired channel on a monitor, which is often a television screen. Media content on bound channels flows uni-directionally from a cable headend to the cable host devices connected to that cable headend.
A digital cable network also uses one or more unbound channels to exchange information other than media content bi-directionally between a cable host device and a cable headend. For example, information regarding upcoming programming on bound channels may be transmitted on an unbound channel from the cable headend to the cable host device. Selection by a user may then cause such programming information to be displayed on a monitor. However, information may also be transmitted from a cable host device to a cable headend, such as registration information upon power up of the cable host device and information necessary for authentication and/or billing upon selection of pay-per-view program by a user.
Although there is no reason that the present invention could not be implemented in a wholly owned scenario wherein both the telephone network and the cable network belong to the same entity, the invention is described in detail herein for the exemplary scenario where two entities must cooperatively integrate separate networks to provide the services.
Referring to FIG. 1, an architecture 100 to host telephone services on a cable host device is illustrated in accordance with an embodiment of the present invention.
