  • the data transmission bandwidth required is therefore considerable. With a lower bandwidth of the transmission channel, corresponding restrictions in the reproduction quality have to be accepted.

  • Set-top boxes of this type can be equipped with a number of additional functions, such as their own processor, working memories, buffers, etc., in order to provide a number of further functions.
  • the disadvantage of these set-top boxes has always been their comparatively high price.

  • the transcoder provided for this purpose is provided with a so-called codec interface.
  • codec is an abbreviation for a compressor / decompressor technology. Interfaces are understood to be those that have a special driver that allows the compression and decompression of data.

  • the additional device is able to decompress the data stream received in compressed form.
  • the additional device can be equipped with a corresponding reading device.

  • the additional device can be further simplified in that the centrally arranged transcoder essentially pre-assembles the related multimedia data objects for display on a television set.
  • the multimedia data objects are adapted to the optical resolution of a television set.
  • the multimedia database objects are thus line-oriented and prepared by the transcoder in a number of lines adapted to the television picture. This facilitates the implementation of the data stream received by the additional device.
  • a further pre-assembly of the television set by the transcoder takes place in that the multimedia data objects are already transmitted by the transcoder into the red, green, blue coding or YUV coding which is common in television technology.
  • the transcoder already combines individual objects that have been transmitted or changed their layout in such a way that a representation on a television set is possible or useful.
  • the transcoder provides a virtual control panel that can be called up by the user via the additional device and then operated further.
