SYSTEMS AND METHODS FOR IDENTIFYING COMPLEX TEXT IN A PRESENTATION DATA STREAM

摘要

Systems and methods of identifying and processing complex text are provided. If a pre­sentation data stream contains a complex text string, a preselected control in the presentation data stream is inserted before the complex text string. A first parameter has a value indicating a control type for controlling processing of complex text, and a second parameter takes one or more values for enabling and disabling the processing of complex text. In processing complex text, responsive to a first predetermined type of control in a presentation data stream, if the first type of complex text processing is enabled, this processing is applied to a complex text string succeeding the first predetermined type of control in the presentation data stream. The first pre­determined type of control includes a first parameter represented by a corresponding value for controlling the first type of complex text processing.
