Embodiment Construction
[0025] In order to eliminate the impact of changes in the network address of the video file storage device, such as the IP address, on the video-on-demand function provided by the service provider, in the embodiment of the present invention, the network video providing system on the service provider side is based on figure 1 The flow shown to realize the video-on-demand function is executed by the on-demand management server in the system figure 1 Each of the steps shown will be described in detail below.
[0026] Step 11: Save the correspondence between the identification information of the video file storage device and the network address of the video file storage device, and save the correspondence between the on-demand parameters and the video file identification. The video file storage device here is a device in the network video providing system, and the identification information of the video file storage device is uniquely corresponding to the video file storage device...

The invention provides a method for realizing video on-demand function. The method comprises the following steps: keeping a corresponding relation between identification information of a video file memory device and a network address of the video file memory device, and storing a corresponding relation between on-demand parameters and the video file identification, wherein, the on-demand parameters contain the identification information of the video file memory device and a storage location of a video file in the video file memory device; generating a video on-demand option corresponding to the demand parameters and sending the video on-demand option to a terminal; determining the corresponding on-demand parameters according to the video on-demand option selected by the terminal, determining a video file identification corresponding to the on-demand parameters, and determining the network address of the corresponding video file memory device according to the identification information of the video file memory device in the on-demand parameters; and generating an on-demand address and sending the on-demand address to the terminal according to the determined network address of the video file memory device and the determined video file identification.
Description
technical field [0001] The invention relates to computer network technology, in particular to a method and system for realizing video-on-demand functions. Background technique [0002] With the development of computer network technology, especially with the increase of network data transmission speed, it is possible to transmit video data through the network, and terminals can watch video content through the network. Then there are various online video service providers. These service providers have their own domain names and video publishing systems, and each video file provided by the service provider has its own on-demand address. The on-demand address generally consists of two parts. One part is the network protocol IP address of the video file storage device, and the other part is the identification information of the video file. The IP address of the video file storage device in the on-demand address is used to determine the location of the video file storage device i...
