Embodiment Construction

[0012] Such as figure 1 As shown, according to the preferred embodiment of the present invention, the device used for video program storage and on-demand method of Ethernet includes Ethernet interface 13, cache memory 12, hard disk 11, and network interface 13, cache memory 12 and hard disk respectively 11 connected to the controller 14 .

[0013] Wherein, the hard disk 11 is a carrier for storing video information, and is a large-capacity hard disk (Hard disk). In the present embodiment, adopt the hard disk of 30G bytes, thus, a set such as figure 1 The device shown can store video data equivalent to 10 movies and can be operated by multiple users simultaneously.

[0014] Network interface 13 is used for providing the channel that IPHD and external network carry out data or order interaction, in the present embodiment, adopts the Ethernet network interface that transmission rate is 100Mbps, thus makes IPHD both can adapt to the reading and writing speed of disk, also can D...

Abstract

Thin invention provides a store and program-ordering device and a method with low cost and convenient connection for broadband IP network video programs containing hard disks, data stream used to store video programs, buffers to be connected with the hard disk for the packet and depacket of IP to provide a buffer to the read / write data and the net work order received of the harddisk. The said controller is used to controt the said hard disks containing auto-detesting, formularized rigid disks, read / write operation and file system and control the said buffer and network interface control.

Description

technical field [0001] The present invention relates to a video program storage and on-demand device (abbreviated as IPHD hereinafter), in particular to a video program storage and on-demand method used in a broadband network or a local area network. Background technique [0002] With the development of network technology, the network is changing towards broadband. Among them, video on demand VOD (Video on Demand) is increasingly becoming an important service in the broadband network. At present, the storage of video data in video on demand is realized by a RAID (Redundant Array of Inexpensive Disk) device controlled by a video server in the network, but this method has a high cost and brings unfavorable factors to the expansion of VOD traffic. Therefore, there is a need for a simple and cheap video program storage and on-demand method. Contents of the invention [0003] The purpose of the present invention is to address the above problems, provide a new video program st...
