In addition, the size of the plurality of thumbnail images displayed on the channel browser 800 is variable.
The pointer 940 is positioned on the first thumbnail image 931 of the plurality of thumbnail images included in the channel browser 800 in response to a user's pointer movement command (S710).
When the pointer is positioned on the first thumbnail image 931, as shown in FIG. 12, a first loading icon 950 is displayed on the first thumbnail image 931 (S720).
The controller 170 determines whether the pointer 940 is located in the first thumbnail image 931 or more for a first time (S730), and the pointer 940 corresponds to the first thumbnail image 931. The display of the first loading icon 950 is maintained until the first time elapses or until the first time elapses until the first time elapses.
Here, the first time may be approximately 1 to 5 seconds, and may vary according to a user's setting or a system load.
In addition, the first

The indication is the first

An image 931 may be displayed when the pointer 940 is positioned for the second time.
For example, the pointer 940 is the first

Alternatively, the pointer 940 may cause the first

.
The display of the first loading icon 950 serves to guide the user to maintain the pointer 940 in the first thumbnail image 931, while the first loading icon 950 is displayed. The broadcast signal corresponding to the first thumbnail image 931 is not loaded systemically. Accordingly, there is an effect of reducing unnecessary loading performance due to frequent movement of the pointer 940.
As a result of the determination in step S720, when the position of the pointer 940 is changed out of the area of the first thumbnail image 931 before the first time elapses, the still image corresponding to the first thumbnail image 931. Is displayed (S741).
On the other hand, as a result of the determination in step S720, when the pointer 940 is located in the first thumbnail image 931 for the first time or more, as shown in Figure 13, the first thumbnail image 931 The second loading icon 951 is displayed at step S740. While the second loading icon 951 is displayed, loading of the first thumbnail image 831 is started to start receiving a broadcast signal of a broadcast channel corresponding to the first thumbnail image 831 (S750). ). After the loading is completed, a video corresponding to the first thumbnail image 931, for example, a preview image 952 corresponding to the thumbnail image is displayed.
Subsequently, the controller 170 determines whether a movement command with respect to the pointer 940 from the first thumbnail image 931 to the other thumbnail image has been received (S760). If a move command is not received and a selection command for the first thumbnail image 931 is received (S771), a broadcast signal of a broadcast channel corresponding to the first thumbnail image 931 is output (S781).
Meanwhile, as a result of the determination of step S760, when a movement command for the pointer 940 is received and the pointer 940 is moved to the second thumbnail image 932, the first thumbnail image 931 is applied to the first thumbnail image 931. The corresponding video, that is, the preview image 952, is displayed for a third time (S770). Thereafter, when the third time elapses, a still image corresponding to the first thumbnail image 931 is displayed (S780).
The third time may be a time until the pointer 940 is located in the second thumbnail image 931 and the loading of the second thumbnail image 931 starts, or the pointer 940 is the first time. After moving out of the area of one thumbnail image 930, the time may be 2 to 8 seconds after a specific time.
The above-described broadcast channel display method according to the present invention may be stored in a computer-readable recording medium that is produced as a program for execution on a computer, and examples of the computer-readable recording medium include ROM, RAM, CD-ROM. Magnetic tapes, floppy disks, optical data storage devices, and the like, and also include those implemented in the form of carrier waves (eg, transmission over the Internet).
The computer readable recording medium may be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And, functional programs, codes and code segments for implementing the above method can be easily inferred by programmers of the technical field to which the present invention belongs.
In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or prospect of the present invention.
