Communications between Analogue Component Production Centers

The introduction of Component Analogue and Digital equipments has created a demand for the transfer of component signals between production areas and centres. Existing plants usually offer a single wire composite link for transfer. A Time Division Multiplex, or MAC format, offers an alternative mode of component transfer without composite decoding errors. The ITV Association Technical Laboratories have developed a wideband system based on the SMPTE SMAC proposals but using a standard sync waveform as carrier, also an ENG development offering best utilisation of existing narrow band, 5 MHz, links. The paper will describe the systems, report on operational experience gained with an ENG equipment within the UK, and on progress towards standardisation in the EBU.
