* Notes on DDS (Display Definition Segment)
- * DDS (Display Definition Segment) tells the decoder how the subtitle image relates to
- * the video image.
- * For SD, the subtitle image is always considered to be for display at 720x576
- * (although it's assumed that for NTSC, this is 720x480, this is not documented well)
- * Also, for SD, the subtitle image is drawn 'on the glass' (i.e. after video scaling,
- + * letterbox, etc.)
- * For 'HD' (subs marked type 0x14/0x24 in PSI), a DDS must be present, and the subs area
- * is drawn onto the video area (scales if necessary). The DDS tells the decoder what
- * resolution the subtitle images were intended for, and hence how to scale the subtitle
- * images for a particular video size
- * i.e. if HD video is presented as letterbox, the subs will
- * be in the same place on the video as if the video was presented on an HD set
- * indeed, if the HD video was pillarboxed by the decoder, the subs may be cut off as
- * well as the video. The intent here is that the subs can be placed accurately on the video
- * - somthing which was missed in the original spec.
