Method and equipment for inputting data to multimedia service database on embedded equipment

Abstract

The invention discloses a method and equipment for inputting data to a multimedia service database on embedded equipment. The method comprises the following steps of: in the process of scanning a multimedia file, storing the generated catalog information of the multimedia file in a random access memory-data backup (RAM-DB), and performing data backup operation from RAM-DB to backup file-data backup (BAK-DB); and if the scanning process is interrupted, continuously scanning after the scanning interruption is ended, copying the data in the BAK-DB into the RAM-DB, and continuously scanning the unscanned multimedia file according to the existing data in the RAM-DB. Two database files, namely the RAM-DB and BAK-DB, are configured in the multimedia service system, and the problem of a multimedia file scanning error due to interruption is solved. The invention realizes high efficiency, data durability and reliability of the multimedia service, improves the user experience of the embedded multimedia service and has high practicality.

Description

technical field [0001] The invention relates to multimedia processing technology, in particular to a method and equipment for entering data into a multimedia service database on an embedded device. Background technique [0002] With the enhancement of computing power and I / O performance of embedded devices, storage devices are used to store a large number of multimedia files. More and more embedded devices can provide multimedia services, Secure Digital (Secure Digital, hereinafter referred to as SD) memory card, USB Universal Serial Bus (Universal Serial BUS, hereinafter referred to as USB) disk and external serial advanced technology accessories ( Permanent large-capacity storage such as Serial Advanced Technology Attachment (hereinafter referred to as SATA) hard disk is generally used for external storage of embedded multimedia service equipment. [0003] The multimedia service program needs to scan the multimedia file, and extract directory information through parsing, ...

AI Technical Summary

Problems solved by technology

[0006] However, the solution of prior art 1 has the following disadvantages: the media service database is lost as the device is powered off, and the next time the media service database and media data need to be recreated, the user needs to wait for a long time

The read and write performance of the media service database is poor, which affects the service response speed

Moreover, the media database is easily damaged due to hot-swapping of the external memory by the user, which in turn leads to abnormal operation of the program

[0009] From the above, it can be obtained that in the solution in the prior art, when the directory information of the multimedia file is entered into the media service database, the directory information in the media service database may change due to the occurrence of an abnormal situation, so that the client program cannot work normally. Use catalog information in the media service database, causing program exceptions and affecting customer experience
