This EIA-775.1 standard includes mechanisms to allow a source of MPEG service, such as a cable or terrestrial set-top box, digital VCR, or DTV to utilize the MPEG decoding and display capabilities in a DTV. A control means using web and Internet protocols is the main feature of this standard. It enables user control of remote appliances via another appliance’s (e.g., DTV or PC) web browser graphical user interface (GUI). The controlled service (e.g., MPEG source) passes requested GUI data to the DTV for presentation typically over the decoded video.
