Abstract
The aim of the invention is to indicate the availability of an update for an MHP application, which is modified only periodically, to the user of a set top box, while helping him or her to decide whether the modified update is actually required and optionally still maintaining the availability of the older update without restrictions. To achieve this, information concerning the scope and/or type of modification in relation to the older version is provided in the transmitted version number for the modified MHP application. The set top box starts the saved older version if special information exists ('launchable with older version' flag) and permits a comparison of the version number with the received version number of the modified MHP application as to whether the modifications of the modified MHP application are of such significance that the modified version must be received and saved in the cache memory. If an update of the cache memory is required, the user of the set top box receives an indication to switch to the narrow-band transponder channel and to receive the modified MHP application.
