Abstract
A signal processing system with multiple electronic apparatus. A controller checks and determines whether or not the electronic apparatus are electrically connected and are compliant for performing a cooperative signal processing. For example, when a TV signal processor is not connected to another apparatus, a signal processing circuit performs normal signal processing. When the TV signal processor is connected to another compliant apparatus, the TV signal processor cooperates with the compliant electronic apparatus as if they were a single apparatus and performs optimal processing of an input signal. In an ID table stored in the controller, processing information concerning processing tasks to be shared with the compliant electronic apparatus is associated with the function ID of the compliant electronic apparatus.
