ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a data processing control device for controlling a plurality of data processing apparatuses, for example, VTR apparatuses and Disk apparatuses, etc. to process AV (video and/or audio) data and a method of the same.
2. Description of the Related Art
In a television broadcasting station, for example, the picture and sound to be telecast is usually produced by recording the materials of the picture and sound to be telecast on video tapes for individual management, reproducing one or more video tapes of the AV data by using one or more VTR apparatuses, combining and editing the reproduced AV data, and recording the AV data to be actually broadcast on another tape.
In such editing, the recording and reproduction control and line control for a plurality of VTR apparatuses are simultaneously carried out.
In such control, one instructs the start of the reproduction processing of a VTR apparatus by depressing a switch on for example a panel or generating a trigger at a set time based on the count of a timer, but this switch operation or the trigger instructs not only the start of reproduction processing of the VTR apparatus, but also the timing for performing the line control.
In an AV data processing control device, when for example both of the reproduction by the VTR apparatus and the line switching control are simultaneously executed based on a trigger generated by a predetermined contact input caused by depression of a switch or the like or the trigger generated by a timer, it is considered that the reproduction command containing the trigger and the line switching command are separately set and processed without linking them with each other.
In the AV data processing control device explained above, however, when it is desired to change for example the VTR apparatus performing the reproduction, it is necessary to individually change all commands related to the settings for the reproduction by the VTR apparatus.
For this reason, there is a problem that there is a high possibility of omission of a command which should be changed and an erroneous change of a command.
Further, there is a problem that the operating time accompanying such a change of settings is long, and thus there is a high possibility that a contact input will be generated during a period when the settings are being changed or the trigger will be generated by a timer at the set time, and only the commands for which the settings had not been changed at that point of time will be executed.
Such a problem particularly occurs where a large number of related commands exist.
Further, when continuously reproducing a material-
2
after a material-
1
, it is considered that in the past the settings for the reproduction for the material-
1
were set, the reproduction of the material-
1
was started by a contact input etc., then the time for starting the reproduction of the material-
2
was found based on this start time and the reproduction time of the material-
1
and the settings for reproduction of the material-
2
were set using this time.
In this case, when changing the settings so as to reproduce the material-
2
in place of the material-
1
for example, it is necessary to invalidate the settings of the material-
1
and newly set the settings of the material-
3
and further begin to set the settings of the material-
2
over again due to the change of the time for start of reproduction of the material-
2
. For this reason, when there are many steps in the setting of reproduction of the material-
2
, the load on the user accompanying the change of the settings is large and, at the same time, a long time is consumed for making the changes.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a AV data processing control device which can correctly perform the change of a command and in addition can reduce the load on a user accompanying a change when a plurality of data processing-apparatuses are controlled by using a plurality of related commands.
In order to solve the above problems of the prior art and achieve the above object, the data processing control device and method of the present invention provide a data processing control device for controlling a plurality of processing apparatuses and a method thereof which process at least one of video and audio data so as to continuously reproduce second material subsequent to first material, having an input means for inputting a plurality of control commands containing a plurality of control commands concerning the first material which indicate the control contents of the processing apparatuses and to which a first identifier is attached, a plurality of control commands concerning the second material to which a second identifier is attached, and a link command for linking the identifier of a first trigger and the first identifier of the control commands and linking the identifier of a second trigger and the second identifier of the control commands; a trigger generating means for generating the second trigger at a time determined based on a time of generation of the first trigger and a reproduction time of the first material; and a command executing means for executing the control commands containing the identifier linked to the identifier of the first trigger when the first trigger is generated and executing the control commands linked to the identifier of the second trigger when the second trigger is generated.
In the data processing control device of the present invention and the method of the same, in accordance with for example the operation by a user, a plurality of control commands including a plurality of control commands concerning the first material which indicate the control contents of the processing apparatuses and to which a first identifier is attached and a plurality of control commands concerning the second material to which a second identifier is attached and a link command for linking the identifier of a first trigger and first identifier of the control commands and linking the identifier of a second trigger and second identifier of the control commands are input to the input means.
Further, by the trigger generating means, the second trigger is generated at the time determined based on the time of generation of the first trigger and the reproduction time of the first material.
The command executing means executes the control commands containing the identifier linked to the identifier of the first trigger when the first trigger is generated and executes the control commands linked to the identifier of the second trigger when the second trigger is generated.
Namely, in the data processing control device of the present invention and the method of the same, by the trigger, executions of a plurality of control commands linked to the trigger are controlled together. For this reason, when desiring to invalidate the execution of these linked control commands all together, it is sufficient to invalidate the link of the trigger and the identifier of the control commands. For this reason, the execution of all linked control commands can be invalidated correctly in a short time.
Further in order to solve the above problems of the prior art and achieve the above object, the data processing control device of the present invention and a method of the same are a data processing control device for controlling a plurality of processing apparatuses processing at least one of video and audio data and a method of the same, wherein a plurality of control commands in which a common identifier is attached to related commands and which instruct the control contents of the processing apparatuses and a link command for linking the identifier of a trigger generated with the count of a timer as a reference and the identifier of the control commands are input; and when the trigger is generated, a plurality of control commands containing the identifier related based on the link command are executed with respect to the trigger.
