Interactive television systems having POD modules and methods for use in the same
The present invention relates to television systems and methods, and more particularly, to interactive television systems having user equipment that includes a point of deployment (“POD”) host device and POD modules for use in conjunction with the POD host device. The interactive televisions systems may have different user equipment arrangements for supporting one or more POD modules. The POD modules may provide a user of the interactive television system with access to various programs and services. The POD module may also implement a back-channel communications link with a service provider. The POD module may also receive modules which may upgrade the hardware or software of the interactive television system.
1 . An interactive television system that provides television programming to a plurality of users over communications paths, the system comprising:
user equipment that is adapted to receive a point of deployment module;
at least one point of deployment module that is configured to be inserted into the user equipment; and
a communications device external to the user equipment and the at least one point of deployment module.
2 . The interactive television system of claim 1 wherein the communications device comprises a back-channel device operative to connect the point of deployment module to a service provider.
3 . The interactive television system of claim 2 wherein the back-channel device couples an input signal from a service provider to the at least one point of deployment module.
4 . The interactive television system of claim 3 wherein the back-channel device comprises:
a signal tap;
a transmitter modulator; and
control circuitry.
5 . The interactive television system of claim 4 wherein the control circuitry is at least partially controlled by the point of deployment module.
6 . The interactive television system of claim 2 wherein the back-channel device is connected to the user equipment.
7 . The interactive television system of claim 2 wherein the back-channel device is connected to the at least one point of deployment module.
8 . The interactive television system of claim 7 wherein the connection between the back-channel device and the at least one point of deployment module comprises:
a transmit enable signal;
a clock signal; and
a transmission data signal.
9 . The interactive television system of claim 8 wherein the transmission data signal is a differential signal.
10 . The interactive television system of claim 2 wherein the back-channel device communicates with the service provider using a proprietary algorithm.
11 . The interactive television system of claim 2 wherein the back-channel device communicates with the service provider using an ALOHA protocol.
12 . The interactive television system of claim 1 wherein the communications device is selected from a group consisting of a cable modem, an ISDN modem, a DSL modem, a telephone modem, a network interface controller, a wireless network interface controller, and a wireless modem.
13 . The interactive television system of claim 12 wherein the communications device is operative to connect the at least one point of deployment module to a service provider.
14 . The interactive television system of claim 1 wherein the at least one point of deployment module has at least one connector configured to connect to the communications device.
15 . The interactive television system of claim 1 wherein the communications device is operative to receive information from a service provider.
16 . The interactive television system of claim 1 wherein the communications device is operative to transmit information to a service provider.
17 . The interactive television system of claim 1 wherein the communications device is operative to receive information from a service provider over an out-of-band frequency.
18 . The interactive television system of claim 1 wherein the communications device comprises an out-of-band tuner.
19 . The interactive television system of claim 1 wherein the communications device transmits information to the at least one point of deployment module.
20 . The interactive television system of claim 1 wherein the communications device transmits information to the user equipment.
21 . The interactive television system of claim 1 wherein the at least one point of deployment receives information from the communications device.
22 . The interactive television system of claim 1 wherein the user equipment receives information from the communications device.
23 . The interactive television system of claim 1 wherein the communications device is at least partially embedded in the point of deployment module.
24 . The interactive television system of claim 1 wherein the communications device is at least partially embedded in the user equipment.
