    "abstract": "The colour broadcasting standards now in use, NTSC, PAL and SECAM, are conventionally referred to as being composite systems. This word is used to differentiate between such systems, which only use one signal path for transmitting a colour picture, and the alternative of the three paths required for the separate transmission of red, green and blue primary signals. The use of a single path for conveying a colour signal made the system compatible with monochrome for operations in studio centres.",

Since 1950, he has been active in the research and development of television studio equipment. He joined the Independent Broadcasting Authority in 1967 as Head of the Video Section and since 1970 his major interest has been in digital television standards conversion, digital video recording and standards for digital television studios. Since 1977, his duties in these fields have been more than that of a consultant. The SMPTE David Sarnoff Gold Medal for 1975 and the Montreux Television Symposium Achievement Gold Medal in 1977 were awarded for his work in DICE (Digital Intercontinental Conversion Equipment).",
