Method for realizing complete recording of important recording information on recording equipment

Abstract

The invention relates to a method for realizing the complete recording of important recording information on recording equipment, and a buffer area is arranged in the recording equipment; in the recording process, when a user stops recording at a time point , the recording equipment saves recorded files and keeps working, and the recorded information is only saved in the buffer area but is notsaved in a storage medium; and when the user finds out that the recorded information from a time point <D> to a time point <F> needs to be saved at the time point <F>, the user can select to save theinformation at the period of time in the storage medium. Because not all the data are written in the storage medium, not only the electric power consumption of a battery can be effectively reduced andthe service time of the battery is prolonged, but also the space loss of the storage medium can be reduced; most importantly, the lost important information can be retrieved to a great degree, thereby realizing that the recording equipment safely records important audio and video information.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method of utilizing cache to realize complete recording of important recording information on a recording device. Background technique [0002] Existing handheld audio and video recording equipment, including recording pens, cameras with video recording functions, and camcorders are basically powered by batteries to ensure portability, and most of the internal storage media tend to have a small capacity. NANDFLASH or other types of memory cards. This will have such a problem in the actual use process. In order to prolong the effective use time of the battery and reduce the waste of storage space, the user stops or pauses the recording when encountering audio and video information that is currently considered unimportant during the recording operation. After a period of time, I found that the audio and video information that was considered unimportant was actually very imp...

Problems solved by technology

There will be such a problem in the actual use process. In order to prolong the effective use time of the battery and reduce the waste of storage space, the user stops or pauses the recording when encountering audio and video information that is currently considered unimportant during the recording operation. After a period of time, I found that the audio and video information that was considered unimportant is actually very important. At this time, the missed audio and video information has not been retrieved.
