Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 Shown is the principle schematic diagram of the inventive method, and its concrete steps of the inventive method are as follows:

[0028] (1) The client sends out a request for vector data access through the Internet.

[0029] (2) The server side preprocesses the vector graphics data.

[0030] After the client sends a request, the server-side database first processes the vector image data as follows according to the client's request:

[0031] a. The client sends an access request for vector graphics data through the Internet

[0032] The description of the vector data in the present invention adopts a method combining the space domain and the time domain, and includes two aspects in data processing. When describing a vector object, go deep into the interior of the vector object and describe it from the two aspects of the freq...

Abstract

The method comprises: a) the client side sends the request for accessing the vectorgraph data through internet; b) server side preprocesses the vectorgraph data; c) transmitting the vectorgraph data through internet.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and in particular relates to a vector graphics data transmission method used in digital home multimedia. Background technique [0002] The vector data structure is a main representation method of the spatial data structure. Vector data is an ordered collection of plane coordinates (X, Y) of discrete points representing graphics, and is mainly used to represent the relationship between the geometric data of graphic elements and their attribute data, which is more accurate than the raster data structure. Precisely determine the physical space location. Because vector data has the characteristics of complex structure, large amount of data, large amount of operation, scale effect, irregularity, discontinuous features and difficult data extraction, the transmission of vector data is different from traditional data transmission. [0003] There are three methods of traditional spatial...
