Problems solved by technology

In addition, although the VIS technology has greatly reduced the download time, in fact, because the image stream is transmitted in an out-of-order manner, it is often necessary to wait for the required files during the process of starting the operating system. Case
Therefore, in the case of using VIS technology, the download time is still relatively long, and there is still the problem of low streaming efficiency

Embodiment Construction

[0038] Hereinafter, the method and system for transmitting image streams provided by the present invention will be described in detail through embodiments with reference to the accompanying drawings.

[0039] First, refer to Figure 2-Figure 3 The method for transmitting video stream according to the present invention will be described.

[0040] figure 2 A flow chart of a method for transmitting video streams according to an embodiment of the present invention is schematically shown.

[0041] First, in step 201, image description information describing each block in the image is generated.

[0042] with reference figure 1 Similar to the transfer image stream of the described prior art, the image is stored in the image storage server and is divided into several blocks. The size of the file division may depend on empirical values, or a more complex strategy or algorithm may be adopted to divide the image into several blocks according to actual applications. This division is...

Abstract

The invention provides a method and a system for transmitting image stream, wherein an image is stored in an image storage server and is divided into a plurality of blocks. The method for transmitting the image stream comprises the following steps: generating image description information for describing each block in the image; using the image description information to generate the access configuration for describing an image stream transmitting scheme which is customized for local computers based on the environment of the local computers; and transmitting the image stream from the image storage server based on the access configuration. The access configuration indicates the sequence of blocks and/or transmission blocks required by the local computers. In addition, the generated access configuration can be also provided for other local computers with the similar environment to be used for transmitting image stream. The invention can be used for transmitting the image stream based on the environment of the local computers, thereby achieving the purpose of customization, improving the efficiency of stream transmission and providing better experience for users.

Description

technical field [0001] The present invention relates to image stream technology, more particularly to a method and system for transmitting image stream. Background technique [0002] Image streaming is a newly emerging data transmission technology, which can be widely used in various fields. In particular, in a network environment, image streaming technology can be applied to booting an operating system. In an application for booting an operating system, a system image, that is, an image of the operating system, is stored in an image storage server. When the local machine is to be booted, the machine sends a request for a system image to the image storage server, and then streams the system image from the image storage server to the local machine. After the download is complete, the local machine can use the system image to boot the operating system. [0003] It has been proved in practice that several advantages can be obtained by utilizing the image streaming technology...
