Problems solved by technology

[0005] When multiple users need to read data in different locations on the same disk at the same time, because the reading speed of a single disk is limited, the disk reading speed cannot keep up, and the data cannot be read, which will cause the TV video card to fail. Phenomenon; when the user fast forwards, rewinds or jumps, the position of a certain block of a certain file cannot be accura

Embodiment 1

[0038] In order to improve the read speed of the disk, make full use of the read and write speed of a single disk, enable the system to locate quickly and timely, and improve user experience, see figure 1 , the embodiment of the present invention provides a method for managing network files, the specific content is as follows:

[0039] Step 101: Unify all network hard disks in the network file system as storage devices.

[0040] Usually, the network file system includes multiple broadcast servers, such as server 1, server 2, server 3, etc. All the network hard disks of the broadcast servers are regarded as a complete set of storage devices, which are managed uniformly by the file management system. Include network disk groups, see figure 2 , the file management system manages disk group 1, disk group 2, disk group 3 to disk group N.

[0041] Step 102: Format all disks in the storage device into different disk blocks.

[0042] Among them, see image 3 , the storage device ...

Embodiment 2

[0062] The embodiment of the present invention also provides a device for managing network files, see Figure 6 , the device includes: a construction module 201, a formatting module 202, an acquisition module 203, a division module 204, an allocation module 205, and a writing module 206;

[0063] The construction module 201 is configured to use all network hard disks in the network file system as a unified storage device.

[0064] The formatting module 202 is configured to format all disks in the storage device into different disk blocks.

[0065] The obtaining module 203 is configured to obtain the block ID of the network file system.

[0066] Wherein, the acquiring module specifically includes: acquiring the block ID of the network file system according to the network disk group ID, the disk ID, and the disk block index.

[0067] The dividing module 204 is configured to divide the file into file blocks according to the size of the file and the size of the disk block by mea...

Abstract

The invention discloses a method and a device for managing network files, belonging to the field of radio and television. The method comprises the steps of using all the network hard disks in a network file system as uniform storage equipment, formatting all the disks in the storage equipment into different disk blocks, dividing a file into file blocks with size equal to the size of disk block by pre-building file, distributing the file bocks into different disk blocks of disk, writing the file blocks into the corresponding disk blocks, wherein the file blocks are corresponding to the information of time code and the position of the file block is located by the information of a time code. The method provided by the invention promotes the whole reading and writing speed of system and the reading and writing speed of single disk is totally utilized. The invention can locate the file block rapidly according to the time code to ensure that the system can speedily locate in time and can further promote the user experienc.

Description

technical field [0001] The invention relates to the field of broadcasting and television, in particular to a method and device for managing network files. Background technique [0002] With the development of the economy, VOD (Video On Demand, video on demand) in the broadcasting industry is welcomed by the majority of users. Each user's VOD video is delivered by the broadcast server. Since each broadcast server can support a limited number of users, the system needs multiple broadcast servers to support a certain number of users, and each broadcast server The corresponding source files are required. The source files of the VOD system are very large and the quantity is huge. If each broadcast server is equipped with complete source files, too many storage devices are required, which increases the system cost. On the other hand, due to the large amount of concurrency of the VOD system and the need for video broadcast jump features, it is required that the read and write spe...
