Media file memory system and fetching mode thereof

Abstract

A media file storage system and its reading method, the media file storage system includes a hard disk, a signal processor, a buffer connected to the signal processor, a storage controller and a network interface, and multiple sector to store system information, and the system information includes a guide table, which is characterized in that: the guide table includes a forward guide table and a reverse guide table; the media file is based on a superframe formed by a plurality of sectors Stored in the hard disk, each superframe corresponds to a serial number, and all serial numbers are arranged in ascending order in the forward boot table, and in reverse order in the reverse boot table; corresponding to Each serial number also indicates the physical storage address where the next superframe is located; the storage system reserves a dedicated channel for each connected user in the hard disk. The invention can quickly and effectively search and read media files such as video and audio for multiple users at the same time.

Description

Technical field: [0001] The invention relates to a media file storage system, in particular to a media file storage system capable of quickly and efficiently reading and searching hard disks such as video and audio files and a reading method thereof. Background technique: [0002] The development of network technology provides the possibility of data transmission between long-distance users, and people rely more and more on the network to transmit some data such as pictures and text. Because the data volume of these materials is not too large, and the requirements for real-time performance are not too high, the delay is tolerable, and the current Internet system can effectively complete these functions. However, with the development of consumer electronics technology, the demand for online playback data is increasing, and because these video and audio programs and data have high requirements for real-time performance, compared with traditional online data such as pictures an...

Problems solved by technology

In the actual operation process, it is possible that the physical addresses stored in the hard disk of the files that the two users that are connected in order may be stored in the hard disk are far apart, and the files that are not connected in sequence are stored in the hard disk. Physical addresses are close to each other

At this time, if the reading is still performed in the order in which the user issued the commands, the total distance of the physical movement of the reading head will be longer, so the physical movement of the magnetic head will take more time, which will cause a greater delay. , affecting the quality of media file transmission
