scope:

The present document specifies the Programme Delivery Control (PDC) transmission system. PDC is a data broadcasting system which carries programme-related information for exploitation by suitably-equipped domestic video recorders. Not all the features specified need be implemented in a particular service. Some of the data is essential if a minimum level of functional performance is to be achieved, whilst other data may be provided only by broadcasters wishing to provide viewers with a higher level of PDC performance. Optional data may be sent at the broadcaster's discretion.
