Description

d6 81 8 2 V. Description of the invention (i) · This issue of March relates to a method and device for multimedia signal adjustment, recording, and playback. In particular, it relates to a method and device for controlling the playback of multimedia signals according to user preferences. . At present, multimedia playback equipment usually provides some adjustment functions to adjust the video and audio signals to the range that users want to receive. However, in multi-segment and multi-channel multimedia, the signal needs to be readjusted frequently. In the following, the audio signals, video signals and multi-channel multimedia of multi-segment and multi-media are discussed separately. 1. Volume of multi-segment multimedia: Currently recordable sound storage media, such as CD-R, CD-RW, DVD-R, DVD-RW, DVD-RAM, memory, hard disk, etc. After the sound signal 'Because the volume of the sound source during each recording is different, there is often a problem that the volume of a certain sound is too high or the volume of a certain sound is too low. At this time, when the user uses a playback device, such as a CD player, to play the recorded audio, it is often necessary to adjust the volume to a volume range suitable for the individual and the environment. When audio signals are recorded on storage media, they are often divided into multiple independent continuous data units. Each continuous sound data records the amplitude of the sound at each sampling time, that is, the volume (which can be expressed by Sig (mT), where T is the sampling period, m is the sampling point), and its maximum volume value is gSigM, as shown in the figure. From the figure, it can be found that the volume signal in the n-I segment is too small, and the volume in the n + 1 segment §fl It is too large. In Figure 1a and subsequent figures, the area between the two dashed lines and B-B 'indicates the user's preference range. When the sound signal is broadcast on the sound player, it can be played by sound. on board

0 8 Ί G 2-V. The volume control device of the description of the invention (2), adjust the volume, the adjustment value is Shift, and the adjusted playback volume value is 18 (1) '1151; (312 (111' ), $ 111 {1 :). So in fact, the maximum volume played by each piece of continuous sound data is SigAdjustM (SigM > Shift). When the S i gM value of each piece of continuous sound data is too large, then The Shi ft value needs to be adjusted to make the Si g Ad jus ΐM suitable for the user's hearing. For example, when the S i gM value of a certain piece of continuous sound data is too large, the human ear will feel uncomfortable, and the Shift value needs to be adjusted. , Make Si small, suitable for the user's hearing; and when the S i gM value of a certain continuous sound data is too small, the human ear will not hear, you need to adjust the sh ift value, so that SigAd jus tK becomes larger. Suitable for the user's hearing, as shown in Figure ib, after adjustment, the size of each volume signal is within the user's preference range. In Figure lb, the signal indicated by the dotted line is the original signal before adjustment, and the solid line The signal shown is the adjusted signal. 2 · Multi-segment multimedia video Degree, contrast, chroma and other parts: Similarly, after recording multi-segment signals in current recordable multimedia, due to the different sources of multimedia, the brightness of some images is often too bright and the brightness of some images is too dark. Problem. At this time, the user needs to often adjust the brightness of the player to a brightness range suitable for the individual and the environment. When the hanging image signal is recorded on the storage medium, it is often divided into several independent continuous data units, and each continuous image The data records the brightness, contrast, etc. at each time point, and its maximum brightness value is Si gM. 'When the video signal is broadcast on the multimedia player, the brightness control device on the player can be used to adjust the brightness. The adjustment value is Sh ift, adjust

The exemption value after the playback is SigAdjus t. (S.i g (nT), Shift). So in fact, the maximum brightness of each continuous image is

SigAdjustM (SigM, Shift). When the SigM value of each continuous image is too different, you need to adjust the Shift value to make the user's vision. For example, when the S i gM value of a certain piece of continuous image data is too large, the human eye will feel uncomfortable. Therefore, the Shi ft value needs to be adjusted to reduce the Si gAd jus tM to suit the user's vision. The S i gM value of a piece of continuous image data is too small, and the human eye will not be able to see clearly. Therefore, the Sh ft value needs to be adjusted to make the Si gAd jus tM larger to suit the user's vision. The above is described for the brightness part, as for other parts such as contrast and chroma. 3. Multi-channel multimedia part: The current multi-channel multimedia volume, brightness, contrast, etc. also have the same situation, for example, multi-channel TV, multi-channel audio machine or multi-view multimedia, etc. 'When the user switches channels or perspectives Sometimes, the volume of channel A is always louder, while the volume of channel B is always quieter. The various situations are the same as described above. As mentioned above, when the SigM values of the parameters (such as volume, brightness, contrast, chroma, etc.) of the continuous sound or image data are too different, you need to adjust the Shift value to make SigAdjustM suitable for the user's hearing. Or visual. However, this adjustment result cannot be recorded and stored. When the multimedia data of the same storage medium is played again, the adjustment action needs to be repeated.

In view of this, in order to improve the problems of the conventional technology, the object of the present invention
