Abstract

The invention provides a set top box multi-screen text scrolling method. The method comprises the following steps: 1, a plurality of single screens are connected in series in a chain table form to form a multi-screen, and each single screen is composed of a first virtual screen, a second virtual screen, a waiting screen and a background screen; 2, when a user needs to display and scroll a segment of characters, structural body data needs to be filled; 3, the structural body data of the characters is obtained, corresponding dot matrix data is found in a set top box library, single-character data in the characters are combined according to a sequence, character data are recombined according to a display effect, and the processed data are inserted into a display queue; and 4, the data in the display queue are successively displayed through the single screens. The invention further provides a set top box multi-screen text scrolling system. The set top box multi-screen text scrolling system can have a plurality of scrolling modes, can control a scrolling speed, and can efficiently and correctly display multi-screen scrolling.
