Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a video recording and reproducing apparatus that can realize functions and operations according to various uses and purposes by exchanging software.

BACKGROUND OF THE INVENTION In recent years, with the spread of video recording and reproducing devices (hereinafter referred to as VTRs), various ways of using them have been devised, and with this, specific applications that can perform unique functions and operations that meet the purpose of use have been developed. Many VTRs are now available. Good examples include an editing VTR for editing video, a dubbing VTR for duplicating video, and an automatic monitoring VTR for recording long-term video. Many VTRs have developed and are equipped with dedicated control circuits to achieve the unique functions and operations described above.

A conventional example of a VTR control method will be explained below with reference to the drawings.

In FIG. 2, 10 is a video recording and reproducing device, 11 is a VTR main unit that performs video recording and reproducing, 12 is a computer that controls the VTR, 13 is a read-only memory for storing software for the computer 12, and 14 15 is software for basic operations of the VTR stored in the read-only memory 13; 15 is software for applied operations of the VTR stored in the read-only memory 13; 16 is an information display section for displaying information in the VTR such as operating status; 17 is V
This is an operation input unit for operating the TR.

A method of controlling the VTR composed of the above-mentioned components will be explained below. Read-only memory (RO)
It is called M. ) 13 consists of software 14 related to basic operations common to any type of VTR, and software 15 related to functions and operations unique to that VTR. The computer 12 operates according to the above two software programs to process the operation commands input to the operation input section 17 and execute the VT.
Controls the R main body section 11 and displays operation information on the information display section 1.
Send to 6.

Problems to be Solved by the Invention However, in the conventional configuration as described above, it is necessary to develop hardware and software each time to perform functions and operations according to the purpose of use, and the development period for this is short. It's huge. Furthermore, since VTRs developed in this way are difficult to use for other purposes, it is necessary to prepare a VTR suitable for each purpose.

SUMMARY OF THE INVENTION An object of the present invention is to provide a VTR that eliminates such conventional pressure points, has high versatility, and can be easily changed to operate in accordance with the intended use.

Means for Solving the Problems In order to achieve the above object, the video recording and reproducing apparatus of the present invention includes a computer that controls the operation of the apparatus, a general-purpose information display section that displays the operating status of the apparatus, and an operation section of the apparatus. The device is equipped with a general-purpose operation input device as a general-purpose operation input device and an auxiliary storage device whose software can be replaced, and is configured so that functions and operations according to the purpose of use can be realized by replacing the software in the auxiliary storage device. .

Operation The VTR of the present invention has the above-described configuration, so that the operation can be easily changed by rewriting the software of the controlling computer via the auxiliary storage device. Therefore, the software can be prepared and rewritten according to the purpose of use. For example, a single VTR can be used in a variety of ways. Also,
By making the information display section and the operation input section general-purpose, the versatility is further increased. In terms of development, hardware development is only required for Class III, and it is possible to deal with this by simply developing software for each VTR with a different purpose of use. This allows for significant reductions in development costs and development time, and also allows users to develop their own VV by developing their own software.
You can create TR.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a control block diagram of a VTR having the functions of the present invention. 1 is a video recording/reproducing machine; 11 is a VTR main unit for recording and reproducing video; 12 is a computer that controls the VTR; 3 is a ROM that stores software processed by the computer 12; and 4 is a ROM 3 that stores the software. VTR
5 is software related to applied operations, 6 is a general-purpose information display unit that has the function of displaying all information in the VTR, 7 is a general-purpose operation input unit that can input all operations, and 8 is applied operations. Software 5
2 is an auxiliary storage device which stores the auxiliary storage device 8 and whose software can be easily replaced. Reference numeral 2 is applied operation software stored in the auxiliary storage device 8 to perform functions and operations according to the purpose of use. Elements with the same functions as those of the conventional example are given the same numbers.

A method of controlling the VTR made up of the above-mentioned components will be explained. ROM3 has VT for different purposes.
Software 4 related to common basic operations is also stored in R. The auxiliary storage device 8 includes software 2 related to applied operations to realize functions and operations prepared in advance according to the purpose of use (for example, automatic editing software to realize special editing operations, long-term recording software for intermittent recording operations)
Application operation software 5 selected from the following is stored. The applied operation software 5 may store the applied operation software 2 as is, as described later, or may read the applied operation software 2 into a memory provided in the auxiliary storage device 8. The computer 12 is controlled by two pieces of software, the above-mentioned basic operation software 4 and applied operation software 5.
It controls the VTR main unit 11 according to the input operation, and further sends operation information to the information display unit 6. When performing another function or operation, the application operation software 5 to be stored in the auxiliary storage device 8 can be selected from among the application software 2 prepared.

Since the information display section 6 and operation input section 7 are versatile, they can be adapted to any application function or operation.

As described above, according to this embodiment, it is possible to realize a VTR that can realize various functions and operations in one unit simply by preparing software according to the purpose of use.

If you need functions that require multiple units, such as editing or dubbing, one for the master VTR and one for the slave VT.
Needless to say, all you need to do is prepare software for R. Furthermore, it goes without saying that the software 2 can specify not only functions but also, for example, the level and frequency characteristics of the output signal.

The application operation software 2 stored in the auxiliary Hafffi device 8 may be an ultraviolet erasable ROM, an electronically rewritable ROM, or a RAM with a backup power supply.
For more advanced functions, use a double buffer structure using a freely readable and writable memory and a magnetic disk reader as the auxiliary storage device 8, and prepare the applied operation software 2 in the form of a magnetic disk. , a VTR with easy software management and replacement can be realized. Furthermore, depending on the case, it is also possible to use an optical disk or the like instead of a magnetic disk.

The basic operation software 4 is stored in the read-only memory 3.
However, it is also possible to supply it from outside, including the basic operating software.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, by providing an auxiliary storage device in which software can be easily exchanged, one VTR can be used for various purposes, and can be used simply by exchanging the software. Since VTRs for different purposes can be developed, the development period and costs can be significantly reduced, and existing VTRs can also be modified to have new functions.

As described above, the present invention realizes a video recording and reproducing apparatus that is extremely useful in practice.
