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.
