摘要
The invention makes it possible to provide a simple means of monitoring access by a set of customers to a set of programs transmitted by a single centre. The centre 1 transmits with intermediate frequencies compatible with the usual television standards for various service programs. A tamperproof set of bidirectional transmission channels, such as optical paths 3, conveys to the customer a number of programs which he selects by controlling a connection box 4. The receiver is connected after its intermediate frequency conversion panel. Metering is initialised at the centre 1 during the time of distribution. Application to the remote distribution of video communication programs. IMAGE
