One embodiment provides a method and apparatus for obtaining metadata program information during channel changes. The method includes the capture of an on-screen display that is rendered by a rendering device such as, for example, a digital television system. The on-screen display may be generated by an access device such as a set-top box in response to a program selection event. Once captured, the on-screen display may be decoded to determine metadata for a program selected by the program selection event. In one embodiment, decoding may be provided using pattern matching, optical code recognition (OCR) or other like decoding technique for decoding a video frame to determine metadata for a program selected by the program selection event. In one embodiment, a copy of the program in conjunction with the captured metadata are stored within the persistent memory of a digital television device. Other embodiments are described and claimed.
