First Claim
Patent Images
1. A method comprising:
- receiving, by a network device that is at a network location and from a gateway device that is at a user location, a first message that comprises an indication of whether a one way device at the user location and unable to transmit data to the network location is tuned to an interactive service;
after receiving the first message, transmitting, by the network device and to the gateway device, a second message that comprises information identifying a location of the interactive service; and
receiving, by the network device and from the gateway device, a third message that comprises information specifying a current channel, frequency or program identifier of the one way device.

Abstract
A system and method of performing data communication upstream to the network central location is provided. A system and method for providing one way devices with video and/or services distributed using switched digital video can be provided. A system may include a one way device, a gateway device, a user operated communication device, and/or a network central location. Such systems and methods allow for greater functionality, customization and/or interactivity to users of one way devices, which do not communicate data from the one way device upstream to a network central location.

12. An apparatus comprising:
-
one or more processors; and memory storing executable instructions configured to, when executed by the one or more processors, cause the apparatus, which is located at a network location, to; receive, from a gateway device that is at a user location, a first message that comprises an indication of whether a one way device at the user location and unable to transmit data to the network location is tuned to an interactive service; after receiving the first message, transmit, to the gateway device, a second message that comprises information identifying a location of the interactive service; and receive, from the gateway device, a third message that comprises information specifying a current channel, frequency or program identifier of the one way device. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method comprising:
-
receiving, by a network device located at a network location, a pre-allocation message from a two-way device that is at a user location; allocating, in accordance with the pre-allocation message, resources for a switched digital video (SDV) channel that comprise a timeframe for the SDV channel and at least one of a channel, frequency, or program identifier for the SDV channel; generating, based on the resources for the SDV channel, a SDV channel resource schedule that comprises at least one of the channel, frequency, or program identifier of the SDV channel; transmitting the SDV channel resource schedule from the network device to a plurality of devices, which comprises the two-way device and one or more one way devices that are at one or more other user locations different from the user location and are unable to transmit data to the network location; and receiving a message that comprises information specifying a current channel, frequency or program identifier of a first one way device of the one or more one way devices. - View Dependent Claims (19, 20, 21)
