An electronic device and method are provided for display of a programming guide for content associated with broadcaster and VOD applications. The electronic device receives a DTV signal that include programming content items associated with broadcaster applications on the electronic device and extracts a set of in-band metadata associated with programming content items. The electronic device selects a set of VOD assets offered by at least one VOD application on the electronic device and extracts a set of out-of-band metadata associated with the programming content items and the selected set of VOD assets from at least one metadata source. The electronic device parses the set of in-band metadata and the set of out-of-band metadata and combines such parsed sets of metadata into a unified metadata file based on a master template. Based on the unified metadata file, the electronic device controls a display device to render a programming guide.
