Problems solved by technology

[0007] Since CMMB is a one-way channel, the interactive capability of CML is of little significance without an uplink channel. In fact, most terminals only need static graphic and text browsing, and CML’s powerful AJAX capability cannot be fully utilized, which wastes terminal resources in vain.

Embodiment Construction

[0018] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Since traditional CML browsers need to perform CML parsing on the terminal side, and the parsing process takes up more resources on the terminal, the present invention adopts and designs a custom lightweight terminal rich media technical specification MiniCML, which is used in The background (server side) processes the CML into different MiniCML packages for different types of terminals through tools in advance, and distributes them. The terminal only needs a very small parsing and rendering engine to complete MiniCML browsing. Using this solution, the background can process the image resources in MiniCML according to the hardware capabilities of the terminal type to maximize optimization.

Abstract

The invention relates to a method for browsing current-mode logic (CML) files on low-end equipment. The method is characterized by comprising the following steps of: generating different static-state composing positions for CML webpage label content based on the resolution ratio of different types of terminal equipment through a WebKit render engine in advance at a server end, and rewriting in the webpage to generate a webpage based on the resolution ratio of different types of terminal equipment; issuing the webpage based on the resolution ratio of different types of terminal equipment generated in step one to the corresponding type of terminal equipment through a china mobile multimedia broadcasting (CMMB) channel; and carrying out render display on image-text in the webpage by the terminal equipment according to the static-state composing positions in the webpage. The terminal equipment is simple in analysis and rendering, and the technical structure for browsing rich text content by the terminal is greatly simplified, so that the resource expenditure is greatly reduced.

Description

technical field [0001] The invention relates to the field of CMMB (China Mobile Multimedia Broadcasting) multimedia broadcasting, in particular to a method for browsing CML files on low-end equipment. Background technique [0002] In the prior art, an Internet browser is usually used as the browser basis, such as IE, WebKit browser, etc. This browser supports powerful functions and can support JavaScript, but the disadvantage is that it is extremely cumbersome, and the program packages are at least more than 10M. Speaking of the RAM and CPU usage, and due to the extremely high complexity, it is basically impossible for this browser to be ported to low-end devices. [0003] In fact, due to the characteristics of the CMMB channel, the actual CMMB business will not send tens of megabytes of webpage resources like the Internet. In addition, CMMB is a one-way network, so many powerful functions of the Internet browser cannot be used at all. [0004] Therefore, the CMMB business ...
