摘要:
According to the invention sub-picture data are organized in sub-picture units, the sub-picture units comprising pixel data in a pixel data area as well as display control data and/or address information data, wherein a sub-picture unit of a second sub-picture stream is inserted into the pixel data area of a sub-picture unit of a first sub-picture stream. This permits several sub-picture streams for systems, which are defined to allow only a single sub-picture stream. Especially for DVD-VR conflicts with the already existing DVD-VR specification are avoided. Therefore, enhanced DVD-VR devices using the invention are able to record and playback additional sub-picture streams and conventional DVD-VR devices are able to record and playback the same signal without any compatibility problems, although restricted to only a single sub-picture stream.
