Definitions

  • the broadcast provider 20 is operable to output digital signals via one or more of the links 30 to their respective users 60.
  • the digital signals comprise at least one of digital programme material, executable software and software-related data.
  • Each user 60 is capable of directing its corresponding STB 40 to select a given digital data stream transmitted from the provider 20, for example for selecting a preferred programme channel.
  • step 150 if the Xlet is successfully validated by the Security Manager, it is loaded onto the Virtual Machine provided by the SBT 40 and then executed in step 160 to provide the user 60 with a corresponding service, for example a weather report, a report of investment bank performance, a stock market report and/or a video game.
  • a corresponding service for example a weather report, a report of investment bank performance, a stock market report and/or a video game.
  • the Security Manager in the STB's 40 is relatively slow in step 140 to execute its validation function with a result that the user 60 must wait a period before a software application icon or similar identified on the monitor 50 appears to respond and function.
  • significant time is required to load the applications in step 130 from the broadcast provider 20 via the link 30 to its associated STB 40.
