Abstract

The invention provides a transmission method and presentation method of a progressive picture based on the XMPP. The transmission method comprises steps: 1) obtaining binary data of a picture file by a picture transmitting end according to a format of a to-be-transmitted picture, and recoding the obtained binary data according to a JPEG progressive encoding mode; 2) recoding the binary data of the JPEG picture after compression through a Base64 method, and converting the binary data into text data; and 3) ordering segmenting the text data after going through Base64 recoding to form a text flow, defining a sending sequence of the text flow through an ID value, and then converting the text data into an ordered xml flow file. In cross-terminal collaborative interaction equipment based on the XMPP, the cross-terminal collaborative interaction is achieved, split-screen presentation and cross-terminal operation of businesses are supported, and then a lot of picture files can be rapidly transmitted in different equipment terminals.

Description

technical field [0001] The invention relates to a picture transmission and presentation method, in particular to a progressive picture transmission method and presentation method based on the XMPP protocol. Background technique [0002] XMPP (Extensible Messaging and Presence Protocol) (formerly known as Jabber) is an open instant messaging protocol based on XML and an Internet standard passed by the Internet Engineering Task Force (IETF). However, the core part of XMPP does not include support for binary data transmission, which limits the basic data of XMPP to text files. [0003] JPEG (Joint Photographic Experts Group, Joint Photographic Experts Group) is a lossy compression standard method widely used for photographic pictures. JPEG itself only describes how an image is converted into a data stream of bytes, but does not describe how those bytes are encapsulated on any particular storage medium. [0004] Base64 is a representation method for binary data based on 64 pri...
