Abstract
Abstract To control the audio-recording mode of a video tape recorder used in a communication system, a plurality of pieces of equipment are connected to each other by communication-control buses for carrying out communication among them. Data "71h" set in an OPC (operation-code) field of a command specifying an audio-recording mode of a video tape recorder indicates an audio-recording mode. RM1 to RM4 sub-fields set in an OPR1 (operand) field indicate whether audio recording is to be carried out on Channels 1 to 4 respectively. SF1 to SF4 sub-fields of OPR2 and OPR3 fields indicate the sampling frequencies of Channels 1 to 4 respectively. NA1 to NA4 sub-fields of the OPR2 and OPR3 fields indicate whether one-channel audio recording, two-channel audio recording or 20 bit audio recording is to be carried out on Channels 1 to 4 respectively. Therefore, by transmitting a control signal conveying such a command, other equipment can specify the audio-recording mode of the VTR.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
172 words
An information-signal recording apparatus employed in a system for communicating information signals and control signals among a plurality of pieces of electronic equipment connected to each other to compose said system by communication-control buses capable of mixing said control signals and said information signals, said information-signal recording apparatus comprising: first means for recording an information signal; second means for controlling operations of said first means and monitoring the status of said first means; and third means for transmitting responses and receiving commands to and from said communication-control buses, wherein said third means transmits along said communication control buses a response indicating an audio-recording mode to other electronic equipment employed in said system in response to an inquiry command transmitted along said communication control buses from said other equipment inquiring said status of said first means, and said second means sets an audio-recording mode of said first means to record audio information in accordance with a recording-mode specifying command received by said information-signal recording apparatus from other electronic equipment employed in said system.
Claim 2
Dependent Claim
172 words
An information-signal recording apparatus employed in a system for communicating information signals and control signals among a plurality of pieces of electronic equipment connected to each other to compose said system by communication-control buses capable of mixing said control signals and said information signals, said information-signal recording apparatus comprising: first means for recording an information signal; second means for controlling operations of said first means and monitoring the status of said first means; and third means for transmitting responses and receiving commands to and from said communication-control buses, wherein said third means transmits along said communication control buses a response indicating an audio-recording mode to other electronic equipment employed in said system in response to an inquiry command transmitted along said communication control buses from said other equipment inquiring said status of said first means, and said second means sets an audio-recording mode of said first means to record audio information in accordance with a recording-mode specifying command received by said information-signal recording apparatus from other electronic equipment employed in said system.
Claim 3
Dependent Claim
118 words
A recording-mode inquiring/specifying method adopted in a system for communicating information signals and control signals among a plurality of pieces of electronic equipment connected to each to other compose said system by communication-control buses capable of mixing said control signals and said information signals, comprising the steps of: returning a response from an information-signal recorder employed in said system as a piece of electronic equipment indicating an audio-recording mode thereof to other electronic equipment employed in said system in response to an inquiry command inquiring an audio-recording mode from said other equipment; and setting an audio-recording mode of said information-signal recording apparatus in accordance with a recording-mode specifying command received from other electronic equipment employed in said system.
Claim 4
Dependent Claim
118 words
A recording-mode inquiring/specifying method adopted in a system for communicating information signals and control signals among a plurality of pieces of electronic equipment connected to each to other compose said system by communication-control buses capable of mixing said control signals and said information signals, comprising the steps of: returning a response from an information-signal recorder employed in said system as a piece of electronic equipment indicating an audio-recording mode thereof to other electronic equipment employed in said system in response to an inquiry command inquiring an audio-recording mode from said other equipment; and setting an audio-recording mode of said information-signal recording apparatus in accordance with a recording-mode specifying command received from other electronic equipment employed in said system.
Claim 5
Dependent Claim
55 words
A recording-mode inquiring/specifying method according to claim 2 wherein a recording-mode specifying command directing said information-signal recorder to enter a recording-mode is transmitted ever said communication-control buses from said other electronic equipment independently from an operation-mode setting command transmitted over said communication-control buses from said other electronic equipment requesting the audio-recording mode said information-signal recorder.
Claim 6
Dependent Claim
25 words
A recording-mode inquiring/specifying method according to claim 2, wherein said information signal is an audio signal and said information-signal recorder is a video tape recorder.
Claim 7
Dependent Claim
27 words
