Problems solved by technology

Therefore, when performing high-definition media on-demand, it is necessary to have enough space on the user's computer disk as a cache to accommodate these very large video files. The phenomenon of playing high-definition movies stuck due to disk read and write, and other phenomena such as insufficient buffer disk space and unable to play movies, etc.

Embodiment Construction

[0010] The invention provides a high-definition media P2P on-demand data transmission and storage method. First, the data files to be downloaded are divided into multiple sub-files in order, and then the remaining space of each disk is detected, and the sub-files are sequentially downloaded to multiple sub-files with remaining space. disk, and then play the sub-files downloaded to different disks in sequence.

[0011] In the process of downloading sub-files, if the current disk is full, it is necessary to check whether other disks have remaining space, and download subsequent sub-files to other disks with remaining space, which will cause all downloaded sub-files to Files may not be on the same disk. Therefore, a guide file can be set up before downloading the sub-files, the guide file records the storage location of each sub-file, and guides the player to find the sub-files to be played during playback, so that the high-definition media files can be played smoothly.

Abstract

The invention discloses a transmission and storage method of program-ordering data of high definition media P2P. Data files to be downloaded are divided into a plurality of sub-files in sequence, the residual space of each compact disk is detected, the sub-files are sequentially downloaded to the plurality of compact disks with residual spaces, and then the sub-files downloaded in the compact disks are sequentially played. By dividing the data files to be downloaded into the sub-files and storing the sub-files compact disks with residual spaces, the invention greatly improves the utilization rate of the spaces of the compact disks and solves the problem that a high definition media file cannot be downloaded and played due to the lack of the spaces of the compact disks.

Description

technical field [0001] The invention relates to a data transmission and storage method, in particular to a high-definition media P2P on-demand data transmission and storage method. Background technique [0002] The development of multimedia technology and Internet technology has promoted people's demand for network streaming media, especially the presentation of complex audio and video content. P2P on-demand technology allows users to watch high-definition movies more smoothly. Most of the current on-demand solutions based on the P2P download principle generate a corresponding temporary file before playing, and then continuously download and fill this file during subsequent playing. However, using the principle of P2P download for on-demand video, because the file is large and involves the function of switching movies, so only one movie file generates a torrent file, like a high-definition movie, the general size is 700M or even 1G ~ 2G. Therefore, when performing high-def...
