Problems solved by technology

[0008] If the TV of traditional technology starts to broadcast high-definition broadcasts, the standard-definition broadcast programs watched by the viewers will be ended and automatically converted to other channels; will be switched to another channel regardless of the will, so there is a problem of causing confusion

[0035] FIG. 3 is a flow chart of the automatic channel switching control method according to the first example of the present invention, and FIG. 4 is a time chart of the automatic channel switching process of the present invention.

[0036] First, as shown in FIG. 3, in the broadcast signal received through the antenna, if the viewer selects a specific channel (standard-definition broadcast) to specify a desired program, for example, to specify the ABCKIDS program, then much The channel allocator 21 separates the transport stream (TS) into video information, audio information, and additional information, and then outputs the video information and audio information to the video / audio decoder 25, and outputs the additional information to the section filter 22. Then the image signal and the audio signal pass through the video / audio decoder 25 and the video / audio processing section 28 , and the image and audio are output on the display section 29 and the speaker 30 . The addition...

[0046] Fig. 5 shows a flow chart of the method for controlling automatic channel switching according to the second example of the present invention.

[0047] As shown in FIG. 5, in the broadcast signal received through the antenna, if the viewer selects a specific channel (standard-definition broadcast) to designate a desired program, the demultiplexer 21 transfers the transport stream (TS) It is separated into image information, audio information and additional information, and then the image information and audio information are output to the video / audio decoder 25, and the additional information is output to the segmentation filter 22. Then, the additional information input to the segmentation filter 22 is sorted in a set format and stored in the database 24 (S51).

[0048] Then, the control unit 27 will search the database 24, and analyze the program specific information of the current channel that the viewer is watching, and judge whether there is a link descriptor in the...

[0058] Fig. 6 shows the flow chart of the method for controlling automatic channel switching according to the third example of the present invention.

[0059] As shown in FIG. 6, in the broadcast signal received through the antenna, if the viewer selects a specific channel (standard-definition broadcast) to designate a desired program, the demultiplexer 21 transfers the transport stream (TS) It is separated into image information, audio information and additional information, and then the image information and audio information are output to the video / audio decoder 25, and the additional information is output to the segmentation filter 22. Then, the additional information input to the segmentation filter 22 is sorted in a set format and stored in the database 24 (S51).

[0060] Then, the control unit 27 will search the database 24, and analyze the program specific information of the current channel that the viewer is watching, and judge whether there is a link descriptor in th...

Abstract

An automatically switching method for digital television and channel for advance noticing the channel switching message and the switched channel to viewer, which contains judging whether there are channel switching information in listened broadcasting signal, if there are, the screen displays channel switching information and switching to other channel when the listened channel is ended or interrupted, displaying the channel switching affirmation for avoiding confusing in switching.

Description

technical field [0001] The invention relates to a television, in particular to a digital television and a channel automatic switching method thereof. Background technique [0002] In general, digital broadcasting transmits additional data together with image data and audio data, thereby providing various services to viewers. However, digital TV broadcasting has different frequency bands depending on the region, and the frequency band used is also limited. Therefore, within the limited frequency band (for example, 7MHz in Australia), in order to transmit standard definition (SD) broadcasting and follow the standard In the high-definition (HD) broadcast, which is several times larger in data than the high-definition broadcast, it is necessary to interrupt the standard-definition broadcast equivalent to the data size of the high-definition broadcast during the time period during which the high-definition broadcast is transmitted. [0003] As mentioned above, during high-defini...
