ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a recording apparatus, a recording system, and a recording method which can automatically perform a recording process by presetting a recording start time and a recording end time and reserving the recording and is suitable when it is applied to, for example, a video tape recorder having a timer recording function.
2. Description of the Related Art
Most of conventional video tape recorders (VTRs) have a timer recording function. In the VTR having the timer recording function, a recording day, a recording start time, a recording end time, a reception channel, and the like are previously inputted and a timer recording is set. In the VTR having the timer recording function, when the timer recording is set, the VTR is set to a mode for automatically recording a program of the preset channel at the recording start time of the timer recording day and the received program is automatically recorded. When the VTR reaches the recording end time, the recording is automatically finished.
When the user sets a recording reservation for a timer recording into the VTR, it is usually necessary to set a recording start time and a recording end time in accordance with a broadcasting start time and a broadcasting end time of a program whose recording is reserved.
In the conventional VTR having the timer recording function, the set contents of the recording reservation such as recording start time, recording end time, and the like which were once inputted are not updated unless otherwise the user manually changes them. Therefore, when a broadcasting of a program such as a baseball relay or the like is extended, a broadcasting time, namely, a start time and an end time of a program to be broadcasted after the extended program is deviated back, so that the VTR cannot perfectly record the target program at the recording start time and recording end time which were set at the time of a recording reservation. Particularly, the problem that the latter half portion of the target program is not recorded.
OBJECTS AND SUMMARY OF THE INVENTION
It is, therefore, an object of the invention to provide a recording apparatus, a recording system, and a recording method which can perfectly record a program whose recording is reserved even in the case where the broadcasting time of a program whose recording is reserved is delayed back because a broadcasting of a previous program is extended or the like.
To accomplish the above object, according to one aspect of the invention, there is provided a recording apparatus comprising: an input setting unit in which a recording start time and a recording end time are set and an audio mode of a signal of a program whose recording is reserved is set; a recording unit for recording an input signal which is received from the source side to a recording medium; an audio mode detecting unit for detecting an audio mode of the received input signal; a counting unit for counting a time while setting the recording start time to a reference; and a recording time updating unit for adding a predetermined value to the recording end time in accordance with the time counted by the counting unit.
To accomplish the above object, according to another aspect of the invention, there is provided a recording system comprising: an operating unit in which a recording start time and a recording end time are designated and an audio mode of a signal of a program whose recording is reserved is designated; a recording unit for recording an input signal which is received from the source side to a recording medium; an audio mode detecting unit for detecting an audio mode of the received input signal; a counting unit for counting a time while setting the recording start time to a reference; and a recording time updating unit for adding a predetermined value to the recording end time in accordance with the time counted by the counting unit.
To accomplish the above object, according to still another aspect of the invention, there is provided a recording method comprising: a recording reserving step of designating a recording start time and a recording end time and designating an audio mode of a signal of a program whose recording is reserved; a counting step of counting a time by setting the recording start time to a reference; an audio mode discriminating step of discriminating whether an audio mode of a signal of a program which is received is a first audio mode as an audio mode of the program whose recording is reserved or not; a recording starting step of starting the recording of a program which is received to a recording medium when it is determined in the audio mode discriminating step that the audio mode of a program which is received is the first audio mode; and a recording time updating step of adding a predetermined value to the recording end time in accordance with the time counted by the counting step when the recording is started.
The above and other objects and features of the present invention will become apparent from the following detailed description and the appended claims with reference to the accompanying drawings.
