SYSTEM AND METHOD FOR CONTROLLING DATA TRANSFER

摘要

The invention which is the subject of this application relates to an apparatus and method for providing a data trans fer system which can be used in the provision of a television service. The invention allows the service to be maintained to the user even though an item of apparatus may have failed and caused the failure of a data stream, by detecting the failure and as a result of the failure allowing the transmission of a replacement stream of data which can be used in substitution of the data stream which has failed. This therefore ensures that there is no or minimum disruption to the television service.
