On the other hand, the pause of the first picture P1 in this example can be directly performed by using the relevant pause button of the time shift function, and can also be completed by the user of the operation of the control device 13.

Of course, in the present invention, after the user completes the screen inspection under the magnifying effect, the enlarged screen can be gradually reduced and adjusted in a relative operation and level. For example, from the second figure (b) or (c) to the original normal play and display ratio as shown in the second figure (a). Furthermore, after ending the pause of the first picture P1, for example, after returning to the second picture (a) for a period of time, or directly operating the associated play button of the time shift function, the design of the present invention can be The content of the first television signal that is still continuously received and temporarily stored in the data buffer 11 is read, and the content after the first picture P1 can be connected to the display 12 to start playing and displaying. In this way, the user can complete the full viewing without missing any original content or segment of the first television signal after completing the aforementioned zoom-in viewing operation.

For the above description of the enlargement and translation adjustment display of the present embodiment, and for the operation of the reduction and parallel display of the screen display adjustment method of the present invention, please refer to the schematic diagrams of the third diagrams (a) to (c). . Wherein the portion of the third diagram (a) is the same as the second diagram (a), but during the operation of zooming out and juxtaposed, the third diagram (a) may be presented as the first television. The content of the signal is continuously played and displayed in real time. As described above, the television signal receiving and processing module 10 of the present invention can simultaneously receive and process corresponding television signals representing a plurality of television channels. The technology of receiving and processing television signals is similar to the display function of Picture In Picture (PIP) which can be operated by a general television device or a television card, so that it can be different on the same display. The picture window presents the TV channel or program content represented by two different television signals, allowing the user to simultaneously view at least two television programs.

In a similar technique, the television signal receiving and processing module 10 of the present invention is designed to simultaneously receive and process television signals of two or more different channels in response to user operations. In this example, in the third figure (b), four television signals are used, that is, in addition to the first television signal, there are second television signals, third television signals and fourth television signals (such as the figure). As shown, the first television signal corresponds to channel CH10 and the second, third and fourth television signals correspond to channels CH9, CH11 and CH12, respectively. When the user is watching the program content of the first television signal and wants to perform the reduction processing, that is, the program content comprehensive function of the adjacent television channel of the present invention, as described above, the user can utilize the control. The device 13 operates the related function button or the physical button, so that the display size of the first television signal on the display 12 can be reduced in a specific ratio, and the other second is displayed in parallel in the remaining area. The program content of the third and fourth television signals, and all of the television signals can be continuously played and displayed in an instant as in the picture display technology.

As described above, as shown in the third figure (b), the display 12 is changed from the display of a single first television signal to the display of four television signals juxtaposed to each other; and in this example, each television The content of the signal has the same display size, that is, the frame display size of the display 12 is equally divided. Therefore, in the reduced operation of the present invention, four display areas of 2 by 2 can be divided on the display 12, thereby providing display of program contents of four different channels. For similar applications, this zoom-out and juxtaposition view technology is also like the photo view function of a digital camera. Users can zoom in on a single photo to display a limited display screen on their camera. The adjacent photo display clusters of 2 by 2, 3 by 3, or 4 by 4 are displayed, and thus multiple photos can be viewed at one time. Therefore, under the image processing of the television signal, the technology can also achieve the purpose of simultaneous viewing of the dynamic broadcast and the plurality of television signals.

In the design of this example, the channels that display mutual juxtaposition and instant play display are channels adjacent to the first television signal viewed by the original user, that is, from the first television signal. One or two adjacent channels forward or backward (ie, illustrated channels CH9, CH11, and CH12). In this way, if the user wants to select an interesting channel for viewing, it is no longer necessary to jump up or down one by one or browse each channel, and can browse multiple adjacent channels at a time by first reducing the size of the original viewing channel. A comprehensive understanding. Furthermore, since the adjacent TV channels may be of the same type, such as a news channel or a sports channel, the user can view and compare multiple channels of the same type at a time, and the display method can be displayed in parallel. Picture technology presents a comprehensive view of more channels. In addition, the completed image parallel display processing is also filled into the image buffer memory 103 to provide an output display corresponding to the user operation.

When the user further performs the zoom-out operation by the control device 13, the presentation pattern as shown in the third diagram (b) can be replaced with the pattern as shown in the third diagram (c). As described above, the television signal receiving and processing module 10 can receive and process a plurality of television signals, so that in the third diagram (c) of this example, the content of the other five television signals can be further increased and displayed in parallel. (i.e., corresponding to channels CH6 to CH8, CH13, and CH14, respectively, such that they appear on the display 12 as a 3 by 3 area display. Similarly, in addition to the channel of the first television signal that the user originally viewed, the other eight channels shown in the third picture (c) are forward and/or the channel of the first television signal (ie, CH10). One to four adjacent channels. In this way, under the reduced size of the original viewing channel, the program content of the television signal of different channels can be comprehensively viewed on the limited frame display size of the display 12.

Of course, under the concept of the present invention, the receiving and processing of the television signal receiving and processing module 10 and the corresponding display of the display 12 can be further changed from 3 by 3 display to 4 times 4 or 5 times 5, So that it is a comprehensive overview of multiples. However, considering the limited frame display size of the display 12 itself, shrinking into any smaller area may be more difficult to provide the user with a clear view or view. In addition, the zoom-out operation is similar to the aforementioned zoom-in operation, that is, at any level of the user performing the zoom-out operation, and then pressing the zoom-in function on the relevant button, the view can be restored to the previous zoom-out level. View and side by side display. For example, it can be restored to the pattern of the third figure (b) after being enlarged from the third figure (c), and can be restored to the pattern of the third figure (a) after being enlarged from the third figure (b).

On the other hand, another feature of the present invention is that the user can directly select the channel to be further enlarged for viewing directly on the side-by-side display as shown in the third figure (b) or the third figure (c). In detail, the user can perform upward, downward or leftward from the original first television signal region (ie, CH10) by the operation of the control device 13 and related buttons, for example, by using a direction button on the remote controller. Move to the right to move to other channels, and then you can use other related function buttons, such as the confirmation button on the general remote control with the function menu to confirm the selected press, so that you can complete the desired process at the same time in the process of viewing. The channel for further viewing is selected, and the content of the corresponding television signal can be normally displayed and played directly on the display 12.

The above embodiments are described in the format of their television signals in a digital format; however, the concept of the present invention can also be applied to analog format television signals. In detail, since the signal of the digital format is required to be performed during the relevant signal processing, if the originally received television signal is in the analog format, the signal needs to be converted after the signal is received. The device is format converted so that subsequent signal processing can be performed. Furthermore, the output display of the television signal can be directly outputted in a digital format, but for a display that is outputted in an analog format, it is necessary to perform a format conversion with the associated signal converter to complete the digital display. The signal after signal processing is displayed as an analog output. However, this technical or hardware design is a conventional technique, and will not be described in detail in the present invention.

In summary, the audio-visual storage and playback system and the corresponding screen display adjustment method provided by the present invention can effectively provide users with better viewing quality and more operational application functions when watching television programs. . By paused the video screen being played, the user can zoom in on the display range of the part and perform corresponding translation to view any detail of interest, and can also reduce the display to other aspects. The TV programs of the adjacent channels are reviewed for viewing, comparison or selection. Allowing users to watch TV not only simply receives information, but also enhances the precise and multi-application of information reception and processing by improving the overall operation technology, thereby obtaining a more complete TV viewing operating environment.
