摘要： A method for near real time data communication is disclosed. The method includes discovering a first device associated with a first location, determining available data from the first discovered device, and inserting a listing for the first discovered device into an electronic program guide (EPG). A data structure in memory is disclosed that includes a device identifier field for containing data indicating an identifier for a discovered device, a name field for containing data indicating a name associated with the discovered device, a receiver available field for containing data indicating a data receiver is available for the discovered device location, an electronic program guide (EPG) field for containing data indicating an EPG and an EPG2 field for inserting listings for discovered device data into the EPG for display to a user at an STB. A system is disclosed for near real time data communication is also disclosed.
