>From an interested party. Rollup Captions To properly represent 608/708 closed captions, it is important that DFXP TimedText provide some basic support for roll-up style captions. [company] has yet to formalize plans in this area, but is proposing the following basic structure: * Allow for a <body>, <div>, or individual <p> element to be tagged as rollup, with an attribute indicating the number of lines of rollup text (typically 2 or 3 lines). * Leverage the proposed upperThird/middleThird/lowerThird region tag to allow for the rollup caption area to be positioned appropriately on the screen. Software that converts 608/708 captions to TimedText can inspect the line positioning and infer the appropriate screen region. * Interpret empty <p> tags as a command to clear the roll-up display. Software that converts 608/708 captions to TimedText would generate an empty <p> tag whenver encountering {EDM} erase commands.
