Embodiment Construction
[0029] Embodiments of the method for enlarging real-time image parts in the digital multimedia broadcasting receiver of the present invention will be described in detail below with reference to the accompanying drawings.
[0030] figure 2 is a streamline diagram of the real-time image partial amplification method in the DMB receiver of the present invention.
[0031] Firstly, in DMB broadcasting, the wirelessly input data is processed and the image is restored.
[0032] Then, the restored image data will be input to LCD or CRT according to each display medium. At this point, the source image is reprocessed, and specific portions are zoomed in and viewed. The following will refer to the attached figure 2 The above method will be described in detail.
[0033] S11, firstly, the user selects a partial enlargement mode of the image on the user interface.
[0034] S12, then, the displayed media picture will appear on the window.
[0035] Here, the above-mentioned window shou...

The invention relates to a real-time image part amplification method in a digital multimedia broadcasting receiver. The real-time image part amplification method in the digital multimedia broadcasting receiver includes the following steps that firstly, a window is displayed in the center on a picture so that an image part amplification mode in a user interface can be selected by a user; secondly, window adjustment is performed, wherein the set window on the picture needing to be amplified is adjusted, and the window size or the window size displayed on the picture is converted; thirdly, window command words for the adjustment are sent to a codec; fourthly, part of the image in the codec is decoded and displayed according to the sent order. According to the real-time image part amplification method, the part needing to be watched by the user in an amplifying mode is selected through the window, the selected part is moved, the window size is adjusted, the specific part can be amplified to be watched, and by means of the advantages of digital media, the specific part can be selected and amplified to be displayed in image data which compose the whole picture.
Description
technical field [0001] The invention relates to a partial enlarging method of a real-time image in a digital multimedia broadcasting receiver. Background technique [0002] Currently used radio broadcasting is a system that receives source signals in analog form. Therefore, when receiving broadcast signals while walking or driving, the sound quality is very poor, so high output efficiency or wider frequency codes are required. [0003] In order to solve the above-mentioned problems, standardization and commercialization activities of digital audio broadcasting are currently being carried out on a global scale. As a digital audio broadcasting standard, Eureka-147 is adopted in Europe using DAB (Digital AudiO BroadcaS"ng), the United States adopts DAR (Digital Audio Radio), Canada adopts DRB (Digital Radio Broadcasts"ng), and the International Telecommunication Union Radiocommunication Division (1TUR) adopts DSB (DigitaI SoundBroadcasting), while South Korea adopts DMB (Digit...
