Method for building a video bus, video bus layout, plug-in card, endoscope and corresponding use

An endoscope (2) comprising

• a video bus layout (9), the video bus layout (9) comprising
• at least one central processor (10), which is connected to at least one multicore bus line (11),
• the at least one bus line (11) comprises a number of cores (12), with a number of slots (13), into which plug-in cards (7) are adapted to be inserted,
• wherein a plug-in card (7) is inserted into one of the slots (13), and
• the cores (12) of the at least one bus line (11) are interrupted at each of the slots (13) such that a connection (19) of the interrupted cores (12) is adapted to be established via the inserted plug-in card (7), and
• the plug-in card (7) comprises
• contact surfaces (14) for contacting contact elements (15) of a respective one of the slots (13), the contact surfaces (14) are connected to at least one pair of contact elements (15) of the respective one of the slots (13) by a signal amplifier (18) on the plug-in card (7),
• wherein the inserted plug-in card (7) is configured to ascertain by at least one of
• trial communication via individual ones of the cores (12) or
• by communicating with the central processor (10),
• which of the cores (12) of the at least one bus line (11) have been assigned by other plug-in cards and which of the cores (12) are available, and
• the plug-in card (7) setting those cores (12) of the at least one bus line (11) to be assigned for its own function, by occupying a corresponding number of the available cores (12),
• such that a self-configuring video bus (8) is obtained;
• and
• wherein the inserted plug-in card (7) is further configured such that, prior to ascertaining the available cores (12), the inserted plug-in card ascertains which of the slots (13) it has been inserted into, and the plug-in card (7) informs at least one of the central processor (10) or at least one further inserted plug-in card (25) which cores (12) are assigned by the plug-in card (7).
