Scalable Content and Aspect Ratio of Your Display

The IS-SPX Player natively supports the SVG graphic language. This language is scalable: that means that the graphics are rendered on the fly according to the resolution supported by the display. This guarantees a perfect rendering for texts and graphics, regardless of the resolution of the display. (Note that the scalable property does not apply on images or video content encoded with other formats and included in a SVG document.)

When authoring scalable content, the user should pay attention to the aspect ratio (the ratio between the horizontal and vertical size) of the display. To avoid aspect ratio distortions or black borders, the user should author the content with the same aspect ratio as the target display.

Digital displays may offer different aspect ratios: the most common are 4:3 and 16:9. The first are those typically seen in

computer monitors: the ratio between the width and height is in 4:3 proportions. The second is common in recent TV sets where the horizontal size is almost the double of the vertical one (landscape).

To simplify the authoring with the right aspect ratio, XPress comes with two sets of templates: one created for 4:3 aspect ratios and one for 16:9. We have also created intermediate aspect ratios such as 16:10 which are less common. When possible choose the aspect ratio corresponding to your displays.
