Abstract

Method and apparatus for using a wide screen television receiver operating at 2fH as a VGA or SVGA monitor. The VGA or SVGA board in a computer is programmed to generate an RGB video signal representing a picture having fewer than a normal number of horizontal lines than a conventional VGA or SVGA picture having a 4:3 format display ratio, in order to define a picture having a wide format disiplay ratio, for example 16:9. The separate synchronizing signals of the RGB video signal are converted to a form recognizable by the video display circuit of the wide screen television receiver.

Explanation (4) • No need to change the analog magnification "Press * the vertical frequency of VGA text horizontal mode is 70.08 Hz * so * for VGA text chess can fill the cheer screen vertically, you need to increase the vertical 霣The analogy on the circuit board is big. The "auto" step is inverted as follows: a) When the vertical synchronization is positive • The combined vertical synchronization signal is L0V (low level). If it is negative, then the vertical positive step signal should not be reversed. B) When the vertical synchronization signal is a negative stage, the combined vertical synchronization number is high. Therefore, because the vertical synchronization signal is already negative, K does not need to be reversed. 〇 * The above conditions can be converted into an anti-mutual exclusion with 2 _persons or a WU5A "嬲 运 集 * as shown in circle 1, one of the _ entry is a vertical step, and the other gun entry is integrated Vertical sync signal * The anti-mutual exclusion or M (U5A) of this album is always the negative sync pulse balance. When the negative sync signal is combined with the negative sync (that is, the dual key input on the album and M U6A), That is, the negative sync pulse signal is formed. Therefore, the VGA round and the VGA test horizontal type are mixed. The synchronizing pulse street will always be the negative signal, and the camera will receive this kind of RGB input signal (躭 is the negative electrode) as the hybrid synchronous input. The above is the hybrid synchronous signal on the negative electrode. In terms of the horizontal balance width and phase of the analog video signal input, the width of its horizontal synchronization signal should be larger than that of the camera II. If this pulse width is not extinguished, it would be wrong to see some wide horizontal synchronization. As a vertical sync pulse, and the camera_Fahi itself is synchronized.

Description of the invention (5) ** Combined with the vertical sync pulse of the negative electrode of M (Boundary Series and M) before narrowing, similarly because of the type The phase of the horizontal sync signal input by RGB video is different from the receiver that can be ignored. • The phase of this K-bit needs to be adjusted before the negative vertical sync signal M is combined. What kind of VGA chess style should be presented? The analogy can be changed at the time of the stove. When the user changes from VGA to horizontal mode to Wenyu horizontal mode or from text to _ horizontal mode, then VGA text in horizontal mode, the analog magnification pressure will change w from the sugar field (user did not draw in) to change Μ keep the power to fill vertically • there are methods to decide which VGA chess style should be presented • in VGA _ shape chess * Vertical sync signal * is negative, in VGA Wenyu chess style • The vertical sync signal is positive, and the polarity M of the vertical synchronization double is used to represent the rendered VGA chess style. * The analog amplification voltage can be used in the VGA text chess style.

The analogy of 霣 K is further explained as follows: In fact, when the vertical synchronization signal changes the hibiscus, it will cause another problem. * As mentioned earlier, the camera only accepts The negative synchronic Panhe sync signal will separate from the Combining the straight and horizontal sync signals to form a hybrid sync signal is not so simple. • In the VGA style, the vertical sync signal of this hybrid sync signal will have errors.

Description of the invention (6) Because the separate VGA synchronization letter «is TTL level and has a very high« period (negative 捶 synchronization letter ») or a very low pass-through period (positive station synchronization signal) If combined with some synchronization signals, the TTL level signal will change the nature of the synchronization signal. The combination of the negative synchronization signal will generate a high series of signals, and the combination of the positive pulses will generate a low logic number. . The value of R1 and C1 as a coupler will be as large as 撢 for cooperation. Therefore, Weipo ’s pressure will not cause changes in the general series of hunger. But it will not be too large. Therefore, when the user changes from VGA When converted to VGA text horizontal format, you can quickly change the general application style, and vice versa. When changing the phase and degree of the horizontal synchronization pulse balance, three non-recoverable monostable multiple oscillators (U3A, U3B, and U4A) can be used at any time. Click the oscillator. The width of the first Confucian cricket oscillator is less than the width of a horizontal susceptor (less than 31.78 microseconds). Select this degree. This first click oscillator ensures that each horizontal susceptor can be triggered If the width of this clicker is greater than one horizontal line, the clicker will only trigger once every two levels. If the width of this clicker is greater than two horizontal sickles *, this click The trigger is only triggered once every three levels. Μ analogy ____, the second tapping device (U3B) locates the horizontal synchronization pulse (adjusts the phase relative to the analog signal drawn by the analog RGB video), and balances the horizontal synchronization. The width of the signal is controlled by the degree of the second tap (U4A > oscillator).
