TECHNICAL FIELD OF THE INVENTION
The present invention relates to a television receiver having a recording / playback function, and relates to a control method suitable for editing a recorded program.
[0002]
[Prior art]
2. Description of the Related Art In recent years, an image recording / reproducing apparatus using a storage medium having random access characteristics, such as a hard disk recorder, has appeared. With the increase in the capacity of the magnetic disk used for this purpose, for example, a moving picture of about 80 hours in total can be recorded with a capacity of 80 GB, and a 30-minute program can be recorded and stored 160 times. In addition, there is a convenient function that allows you to view another recorded program while recording using random accessibility.
[0003]
However, while many programs can be stored and become convenient in this way, when the magnetic disk becomes full, it is necessary to delete unnecessary files, and as described above, a large number of programs must be deleted. Choosing unnecessary files from among them is a daunting task. As a function, there is a function of automatically deleting a file having an old recording date and time, but a trouble that a necessary file is deleted also occurs. Therefore, it is necessary to perform processing such as adding a protection mark to the stored file or moving the file to another recording device.
[0004]
Therefore, recently, for example, a product in which a hard disk and a DVD recorder or a VTR are simultaneously mounted has appeared, and a required file can be edited on a removable medium such as a DVD or a VTR tape. Examples of these editing functions include the following documents, for example.

[0006]
[Problems to be solved by the invention]
Editing is relatively easy in a system such as a hard disk and a DVD, and a hard disk and a VTR as described in the above-mentioned prior art. However, except for the time of editing, only one of the recording and reproducing functions is used. Then, there is a problem that the cost is increased by having two types of recording media. On the other hand, in the case of a recording device of a single recording medium such as a hard disk, it is necessary to perform recording and editing on a recording device connected to the outside, and it is necessary to perform reproduction and recording operations on each device. In particular, when editing a plurality of programs, the number of operations increases, which is very troublesome.
[0007]
[Means for Solving the Problems]
In a television receiver having a video recording / playback function of recording or playing back video, a terminal for outputting a playback image of a video recording / playback unit to the outside of the receiver is provided, and playback control of a video recording / playback device is provided to the output terminal. A function is provided for controlling the recording control of the connected external recording device in an interlocked manner. Any external recording device such as an existing VTR or DVD recorder may be used.
