CA 2360552

Elements necessary for a digital television receiver are structured as a plurality of digital signal processing blocks and a host arithmetic operation processing block. The blocks are connected through a general purpose bus. Commands for controlling operations of the blocks and data of a stream are transferred through the bus. When an encryption encoder /decode is disposed in each block, contents transferred through the bus can be protected. When an encryption encoder / decode circuit is disposed in an interface to which an extension plug-in card is attached, contents that are output from the interface can be protected.

Les éléments nécessaires à un récepteur de télévision numérique sont divisés en plusieurs blocs processeurs de signaux numériques et en un bloc microprocesseur central. Ces blocs sont connectés par des bus généraux, par lesquels les instructions et les flux de données sont transférés pour permettre de commander les opérations de ces blocs. Un circuit codeur/décodeur de cryptage est prévu sur chacun des blocs pour protéger les contenus transférés via ces bus. Un circuit codeur/décodeur de cryptage est également prévu sur une interface avec cartes d'extension enfichables, afin de protéger les contenus extraits de l'interface.
