Abstract
When trying to make a correct connection, a VCR 13, which should be connected to terminal 15, is connected instead to terminal 16 by mistake, so that a signal generator 13a constructed internally within the VCR 13 outputs a test signal, but the switcher 8 selects the signal being input at terminal 15 (where there is no signal present), and provides it to detector 12, but as there is no signal at terminal 15, the CPU 5 determines that the connection is incorrect and displays a user prompt to this effect on the CRT 10.
Claims18
An audio visual equipment with a digital bus system comprising:
- a CPU for outputting a control signal;
- control means for controlling one or more external apparatuses based on said control signal from said CPU;
- switching means for selecting one of said external apparatuses in order to receive an information signal from the selected external apparatus;
- detecting means for detecting said information signal received by said switching means;
- and
- displaying means for displaying said information signal received by said switching means,
- wherein said control means and said switching means are controlled by said CPU, and
- wherein each of said external apparatuses connected to said switching means includes a signal generator for generating test signals.
A method for initializing and confirming connection of a system comprising the steps of:
- showing a system connection and/or configuration model to the user;
- generating a test signal for confirming said model;
- and
- detecting said test signal.
A method for initializing a system, comprising the steps of:
- sending a predetermined command via a digital bus line;
- going through predetermined processing steps for deciding a system status;
- and
- storing a system configuration in a non-volatile storage means, wherein said predetermined processing steps for deciding system status include
- sending a command by said digital bus to a predetermined address number,
- changing said address number to a new address if an acknowledgement signal is received from an apparatus, and
- if said acknowledgement signal is not received from an apparatus, assigning said new address to an apparatus not having an assigned address.
