The links above go to 471 documents that were contributed in 2019 and 2020 by Stephen Craig (262), Jeff Bottom (85), Nick Cutmore (63), Nick Bentley (43), John Sykes (9) and Unknown (9).  A considerable amount of processing was also carried out by Nick Cutmore.

The documents were created by staff at BBC Engineering Training Department for use on various courses.  They were produced between 1963 and 1996 and they provide a good record of that era's broadcasting technology. Massive changes have taken place due to the advent of digital broadcasting so, apart from fundamental principles, they no longer provide information on systems that are in use by the BBC.

The sheets were only intended for use by people attending courses and their format reflects the fact that they were not intended for general publication.  BBC technicians and engineers found them very useful and tended to hang on to them for many years as they provide succinct information on the most relevant aspects of each subject.

Acknowledgement and Restrictions

Without the huge amount of work done by the contributors named above it is likely that the content would eventually have been lost.   It took about 300 hours and this effort is gratefully acknowledged.

The BBC has given permission for many technical documents from the above era to be published on bbceng and this support for the preservation of BBC engineering heritage is gratefully acknowledged.

As broadcast engineering has developed a great deal since since these Information Sheets were produced, the documents do not represent present techniques.  However, you must adhere to the following Terms and Conditions:
