BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and system, and in particular to an electric power file or data in the case of an deficiencies. [Prior Art] Power adjustment of portable audio and video playback device, portable audio and video playback device power adjustment mode, full playback of audio and video multimedia due to the continuous push of technology in the Shaanxi, Dan, make the # ^ ^ come out The popularity of the new ~9 sound and light equipment -i has become an indispensable preparation for everyone's life, heart = 2 CD / DVD player and a variety of audio devices, *, with the enjoyment of technology to provide users Outdoors is still in the autumn, "the audio and video player", θ Γ11,, τ 贝, listening to multimedia files or materials: However, this portable audio and video player, where the supply of power is limited It is easy to cause a lot of trouble in use. Currently, portable audio and video players used in the market, such as an MP3 player or a notebook computer, must be equipped with a battery to supply the required ones. Electricity, in order to play multimedia files or materials, η The storage capacity of these batteries in the absence of an external charging device, most of them can provide power supply status of about two hours, in the case of notebook computers, ^ Independent power supply In the case where only the power of the battery is used to supply electricity, if you want to watch a movie recorded in a DVD format, the power of the battery is often used up in the middle of watching the movie, so you can only watch the movie halfway. Must stop, causing the user to not enjoy the movie, so it is very uncomfortable

Nickname.9213343L V. Invention description (2) Impression of service. In the prior art, there is another amount of power, or less power consumption, however, the impression that the movie is watched or the file is half uncomfortable. Through the above-mentioned radio, the power is exhausted in the half of the conventional source of independent electricity, which is actually improved. In order to propose a reasonable design, the method of improving the battery structure can be improved by using the missing method to increase the battery: portable In the audio and video player, the subtraction method or device still can not let the user, the music is finished, and the power of the player can only be turned off in the shadow, so that the user can leave a technical description to know that the current portable audio and video Under the condition of the situation, it often causes the film or the music to be released, which cannot provide the user with complete hearing or visual inconvenience. Therefore, the inventor has the feeling that he is dedicated to research and cooperate with the application of the theory, and finally improve effectively. The invention described above is missing. SUMMARY OF THE INVENTION The main purpose of the thunder is to provide a portable audio and video playback device source depletion = two Ϊ = and the system, so that the portable video playback device can be in the electric method ii After the audio-visual multimedia slot or data is released, the reading: is to measure the current amount of power a remaining in the power unit, the second media standard or data, and calculate the file or data c; If the average power consumption file of the portable video playback device or the remaining power a of the portable audio and video playback device cannot be fully played, the audio and video multimedia can be publicly available, thereby reducing the output of the video or audio; Reduce the power consumption of the intercom (3) 撩 装置 device, so that the portable audio and video playback

In order to enable your review committee to further understand the technical features of the present invention, please The following is a detailed description of the invention and the accompanying drawings, which are merely provided for reference and description, and are not intended to be used in the present invention. [Embodiment] refers to a power adjustment method of a portable video playback device. And the purpose of the system is to enable the portable video and audio playback device to completely complete the audio and video multimedia files or data before the completion; the first/voucher, please refer to the second picture, which is a portable video and audio. The structure of the playback device 10 is shown as a voice U 只 only: the 'is described by a notebook computer'. However, it can be applied to the ΜΡ3 player or various hand-held devices, which is not implemented by this embodiment. The examples are limited. And the dial-up device 10 includes a power unit 19' for providing the power required by the portable video-recording device 1 : the user will include an audio-visual multimedia file Or the processing-processing unit 13 adds the audio file or the data processing unit 13 to the multimedia (audio signal), and then: not like the Licensing) and the audio field knife, the video and audio Passing the gs 17 and the audio thick element 15 to do more into a + ♦ ♦ decorated to the video early 兀 Ling further processing, for video and audio page 7

Dial out. In this embodiment, the video player dials the ND 101 VCD/DVD player, and the power unit 19 can also be a battery. Please refer to the second figure, which is a circuit block diagram of the portable multi-discharge device of the present invention, wherein the power unit 1〇9 system=7 dialing unitary unit 13, sound effect The unit 1〇5 is used to = TC107 for the power supply required for each early operation, and the processing unit 13 detects the current power of the power unit 1〇9 at intervals. It has been determined that the current power of the power unit 1〇9 is in the state of full power or insufficient power, but the interval time can be set to be detected once every three or five minutes. The portable video playback device 100 is internally provided with a processing unit lj, which is respectively connected to the video playback unit 1, the audio unit 1〇5, the video unit 107, and the power unit 丨09. The processing unit. With the video playback unit 101, the playback time b (or remaining time) required for the audio and video multimedia file or the material and materials can be calculated instantaneously, and the processing unit j 3 will also begin to calculate the portable video playback. What is the average power consumption c of the device per second, thereby whether the video multimedia file or data can be completely played back compared to the power remaining a before. When the processing unit 13 calculates that the remaining power a divided by the average power consumption c is less than the playback time b, the signal command is sent to the sound and effect unit and the video unit 107 to reduce the two units (sound effect) The video and audio output of the unit 1〇5 and the video unit 107 are first connected to the processing unit 13 by receiving one of the pins of the audio unit 105 for receiving the signal command, thereby reducing the sound effect unit i 〇5 Audio output, such as lowering the sound unit

Or special special effects, in order to extend power

However, dealing with the decoding rate of 蕈·Q video and audio, the power consumption of the multimedia files or data of the sub-cameras, or the current level of power consumption, is more than 44% of the portable video playback devices. / Technically, the sampling rate of the sound is greatly compressed or decoded, and the ratio of the image is reduced to MPEG4 format to reduce the resolution of the video. The sampling rate of the image and the compression of the image allow the power unit to be added to the power supply unit of the power supply unit 109. The power consumption is greater than the playback time b. Although the system automatically reduces the video and the burglary will still be measured at the beginning of each time, the processing unit 13 media file or data is released, 5 22 or not It is possible to change the video and audio by the 'average power consumption c and the amount of the door has been changed when the dialing is changed'. The amount of the change is also the change. The depreciation time will also change accordingly. At this time, the processing unit 13 calculates again a. / Change the average power consumption △ (:, -^b), if a / (c - △ 〇 ^ (13 ~ / ^ one, eight 0 is greater than or equal to (匕 and audio rotation.
