Abstract :
We present an extension of the current LaserVision video disc format that includes a digital audio signal. We show 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, enabling the realization of a compatible system. For the PAL and SECAM video formats we show the feasibility of digital audio, but unfortunately it cannot be combined with the analog audio carriers.
