Digital Audio Modulation in the PAL and NTSC Optical Video Disk Coding Formats

Document Thumbnail

An extension of the current optical video disk format that includes a digital audio signal is presented. The feasibility of a combined digital audio signal according to the Compact Disc digital audio format and the current analog audio signals in the NTSC video format is described, which permits the realization of a compatible system. For the PAL and SECAM video formats the feasibility of digital audio is shown, but it cannot be combined with the analog audio carriers.
