when a channel is switched during the storing of the first broadcasting program, storing the channel-switched second broadcasting program in the storage device and sequentially extracting second thumbnail images from the second broadcasting program; and outputting the first thumbnail images, a program representative thumbnail of the second broadcasting program, and the second thumbnail images. ### Claim 2 (depends on 1) The operating method according to claim 1, further comprising: extracting the program representative thumbnail of the second broadcasting program from additional information of the second broadcasting program. ### Claim 3 (depends on 1) The operating method according to claim 1, further comprising: generating the program representative thumbnail of the second broadcasting program using additional information of the second broadcasting program. ### Claim 4 (depends on 3) The operating method according to claim 3, wherein the generating the program representative thumbnail of the second broadcasting program using additional information of the second broadcasting program includes generating the program representative thumbnail using at least one of broadcasting channels, broadcasting program titles, broadcasting time, broadcasting detailed information included in the additional information of the second broadcasting program. ### Claim 5 (depends on 1) The operating method according to claim 1, wherein the outputting the first thumbnail images, a program representative thumbnail of the second broadcasting program and the second thumbnail images includes outputting the program representative thumbnail of the second broadcasting program between the first thumbnail images and the second thumbnail images. ### Claim 6 (depends on 1) The operating method according to claim 1, wherein the program representative thumbnail is displayed to be distinguished from the first thumbnail images or the second thumbnail images. ### Claim 7 (depends on 1) The operating method according to claim 1, further comprising: outputting the program representative thumbnail in a list of the recorded broadcasting programs. ### Claim 8 A broadcasting receiver, comprising: a storage device that stores a first broadcasting program received from a predetermined tuner and, when a channel is switched during the storing of the first broadcasting program, stores the channel-switched second broadcasting program; a thumbnail image extracting module that extracts first thumbnail images from the first broadcasting program and stores the first thumbnail images in the storage device and when the channel is switched during the storing of the first broadcasting program, sequentially extracts second thumbnail images from the channel-switched second broadcasting program and stores the second thumbnail images in the storage device; a program representative thumbnail generation module that generates a program representative thumbnail of the second broadcasting program; and an output module that outputs the first thumbnail images, the program representative thumbnail of the second broadcasting program, and the second thumbnail images. ### Claim 9 (depends on 8) The broadcasting receiver according to claim 8, wherein the program representative thumbnail generation module extracts the program representative thumbnail of the second broadcasting program from additional information of the second broadcasting program. ### Claim 10 (depends on 8) The broadcasting receiver according to claim 8, wherein the program representative thumbnail generation module generates the program representative thumbnail of the second broadcasting program using the additional information of the second broadcasting program. ### Claim 11 (depends on 10) The broadcasting receiver according to claim 10, wherein the program representative thumbnail generation module generates the program representative thumbnail using at least one of broadcasting channels, broadcasting program titles, broadcasting time, broadcasting detailed information included in the additional information of the second broadcasting program. ### Claim 12 (depends on 8) The broadcasting receiver according to claim 8, wherein the outputting module outputs the program representative thumbnail of the second broadcasting program between the first thumbnail images and the second thumbnail images. ### Claim 13 (depends on 8) The broadcasting receiver according to claim 8, wherein the program representative thumbnail is displayed to be distinguished from the first thumbnail images or the second thumbnail images. ### Claim 14 (depends on 8) The broadcasting receiver according to claim 8, wherein the outputting module outputs the program representative thumbnail in a list of the recorded broadcasting programs.
