Embodiment Construction

[0016] Such as figure 1 Shown is a schematic diagram of the operating environment of a preferred embodiment of the progressive data encoding transmission system of the present invention. The progressive data coding transmission system 100 runs in a client 1, and the client 1 is connected to a server 2 through a network. In this embodiment, the network complies with Transmission Control Protocol (Transmission Control Protocol, TCP).

[0017] The server 2 mainly includes a memory 20 , an encoder 22 and a buffer 24 .

[0018] A progressive data coding transmission unit 200 is stored in the memory 20 . The progressive data encoding transmission unit 200 is composed of one or more computerized program segments, and interacts with the progressive data encoding transmission system 100 in the client 1 to realize progressive encoding and transmission of data.

[0019] Specifically, the progressive data encoding transmission unit 200 is used to respond to the request of the client 1,...

Abstract

The invention provides a progressive data coding transmission system. The system comprises an acquiring module for acquiring the current window size of a client and storing the current window size; a request module for requesting the server to code data in the progressive coding transmission mode and temporarily storing the coded data in the buffer of the server; an adjusting module for determining the fractional transmission quantity of the server to transmit coded data according to the progressive coding transmission mode, comparing the current window size of the client with the window size thereof during the last data transmission process, and determining the fractional transmission quantity of the currently transmitted data of the server according to the comparison result; and a receiving module for notifying the server of receiving the transmitted data of the server according to the determined fractional transmission quantity. According to the technical scheme of the invention, the defect in the prior art that better pictures cannot be resolved at a first time through the progressive coding transmission process can be overcome.

Description

[0001] This application is a divisional application of a patent with the application number 2012105611464, the application date is December 21, 2012, and the invention name is "progressive data encoding transmission method". technical field [0002] The present invention relates to a data transmission system, in particular to a data progressive encoding transmission system. Background technique [0003] Currently, there are two ways of displaying pictures on the Internet: sequential coding and progressive coding. Sequential coding means: the pictures are processed from left to right and top to bottom and then displayed on the screen. The progressive encoding is to first display the general outline or blurred image of the picture on the screen, and then slowly supplement the detailed information of the picture according to the client's request, and transmit the picture from blurred to clear. The current progressive encoding uses a fixed amount of data to transmit a picture t...
