Abstract:
1. A method of performing a time-shift function in a television receiver having a personal video recorder enabling a time-shift function, the method comprising: receiving, via a network interface, a first broadcast program having audio and video data, wherein the first broadcast program corresponds to a current broadcast program; demultiplexing and decoding the received audio and video data; processing the decoded audio data into an audible data and the decoded video data into a displayable data; storing, in a memory, a group comprised of second broadcast programs, wherein the second broadcast programs correspond to previously stored broadcast programs; receiving, via a user interface, a user's command signal; accessing, via a controller, the memory and forwarding the group comprised of second broadcast programs to an on-screen display (OSD) generator if the user's command signal is received; generating, via the OSD generator, a time-shift guide OSD for the previously stored broadcast programs, wherein the time-shift guide OSD has a single progress bar for the previously stored broadcast programs, and an indicator of the single progress bar is movable in multiple regions corresponding each of the previously stored broadcast programs; displaying, via a display module, simultaneously both the video data in the first broadcast program and the time-shift guide OSD corresponding to the group comprised of second broadcast programs, wherein the time-shift guide OSD comprises an additional region indicating an available memory space; displaying first thumbnail image data in the time-shift guide OSD if the indicator is positioned at a first region among the multiple regions, wherein a position of the first thumbnail image data is changeable depending on a position of the indicator; and displaying second thumbnail image data in the time-shift guide OSD if the indicator is positioned at a second region among the multiple regions, wherein a position of the second thumbnail image data is changeable depending on a position of the indicator.
