All India Radio’s (AIR) Transcription and Programme Exchange Service is primarily involved in archiving, transcribing, and exchanging radio programmes. Its core units include the Central Archives, Sound Archives, and Transcription Unit, along with a Programme Exchange Unit. An ‘Advanced Research Unit’ is not typically listed as a standard component of this specific service. AIR does have research and development wings, but they are separate from the archiving and exchange function.
The Transcription and Programme Exchange Service of AIR focuses on preserving and distributing audio content.
The Central Archives of AIR hold historically significant recordings, while Sound Archives house a wider collection. The Transcription Unit is responsible for preparing written versions of broadcasts. The Programme Exchange Unit facilitates the sharing of programmes among different AIR stations and with other broadcasting organizations.
