Embodiment Construction

[0041] 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.

[0042] The production of movies and TV programs mainly includes the production of video and the production of subtitles, wherein the production of subtitles is usually completed by a subtitle machine. The traditional subtitle machine is generally composed of a PC plus a professional subtitle superimposition card and corresponding software, which is used to superimpose graphic subtitles on the video signal. The characteristics of the subtitle machine are: real-time superimposition, no need to generate, bright colors, small signal loss, suitable for superimposing station logos, corner logos, left fly advertisements, etc. on TV stations.

[0043] Above-mentioned traditional subtitle machine does not have drawing function, just is use...

Abstract

The invention provides a caption machine with a real-time drawing function and a drawing method thereof, which is used for solving the problem that the real-time is not met in an existing drawing method. The caption machine comprises a real-time acquisition module, a data sampling module, a drawing module and a primitive generating module, wherein the real-time acquisition module is used for monitoring whether transaction data at a network end is updated in real time; and if the transaction data is updated, the updated data is copied to the local; the data sampling module is used for reading the data for sampling from the local; the drawing module is used for drawing multiple types of stock market analysis charts by using sampling data; and the primitive generating module is used for replacing preset template primitives by using the drawn stock market analysis charts so as to generate graph playing primitives. In the process of playing a program, the caption machine can draw multiple types of stock market analysis charts in real time with the changes of actual information, and the multiple types of stock market analysis charts can be transmitted to a television signal in real time for playing.

Description

technical field [0001] The invention relates to the technical field of subtitle machines, in particular to a subtitle machine for real-time drawing and a drawing method thereof. Background technique [0002] With the promotion of new technologies and informatization in the field of radio and television, more and more TV stations have set up "economic channels" or "financial channels", which are specially used to produce and broadcast some financial news and special programs. To release the latest, most timely and most important stock market quotes and related information. [0003] In such programs, various charts are often used to visually analyze stock market data, among which time-sharing trend charts and K-line charts are the two most common stock market analysis charts. The time-sharing trend chart is also called the real-time trend chart. It is a technical graphic that displays the market transaction information on the coordinate chart with curves in real time. The ho...
