  • Publication number: 20150245102
    Abstract: A method and apparatus for accessing content is capable of retrieving and selecting information is facilitated by using uniform operations. Symbols corresponding to pre-recorded programs contained on a recording medium are displayed on a screen. In response to selecting one of the symbols, representative frames comprising the program are displayed on the screen. In response to selecting a representative frame, a portion of the program is played back. In a recording device, content is accessed by displaying a representative frame from each of a number of user-defined streams. At least a portion of a stream is played back in response to selection of the corresponding one of the representative frames.
