Abstract

Video recording according to the DVD-VR Specification allows to record only one sub-picture stream. Therefore, a new technique is provided in order to be able to record at least two different sub-title streams in such a way that the sub-pictures of the different streams may be displayed optionally. A first sub-picture stream is directly copied to the DVD-VR disc, whereas a second or third sub-picture stream is transcoded to Teletext format so that the data can be included into the video stream to be recorded on the DVD-VR disc. Thus, several sub-titles are available during replaying a DVD-VR disc.
