Abstract

PURPOSE:To facilitate the change of reservation contents by holding a function to shift simultaneously a picture recording start time and a stop time at a timer. CONSTITUTION:The reservation setting of a timer is executed by inputting the data such as the reservation date, picture recording starting time, completion time and picture recording channel number and a microcomputer 1 for a timer stores these inputted data onto an internal RAM. The microcomputer 1 for a timer has a clock function and holds the data of the present time. The present time data and the timer reservation data are compared, the command such as the picture recording start and completion is sent to the microcomputer 4 for a system control in accordance with a timer action and the microcomputer 4 for the system control controls slave blocks 5-7 and thus, the picture recording is executed. Thus, the reservation contents can be easily changed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to software installed in a VTR or the like that performs timer processing for recording while the user is away, and to a timer function generated by this software.

[Conventional technology]

Conventionally, this type of timer is processed by software using a one-chip microcomputer, and its general functions include storing recording start and stop times, receiving channels, etc., and starting recording based on the stored data. and stopped.

[Problem to be solved by the invention]

The main purpose of the above-mentioned conventional timer is to record at a desired time, and there are various ways to set the time, etc., but basically they are used to record start and stop times. The only thing that was done was to do the following. However, if we consider the current state of TV broadcasting, we have begun to see many sports broadcasts where the end time of the program is extended. As a result, all broadcast times of programs after the extended program are shifted.

At this time, it is necessary to shift the timer setting time (both start and stop), but with the conventional timer function,
Such modifications require the same amount of effort as resetting.

[Means to solve the problem]

The VTR timer of the present invention has in its software a process for changing only the start and stop times of the timer.

〔Example〕

This will be explained below with reference to the drawings.

FIG. 1 shows a block diagram of a VTR centered on the control system. One-chip microcomputer for timer
In addition to the clock function and timer reservation function, it also controls the display unit 2,
It has functions such as scanning the key matrix 3 on the front panel. The one-chip microcomputer 4 for system control includes a signal processing circuit 5. mechanism 6,
Each block on the slave side, such as the tuner circuit 7, is controlled. The timer one-chip microcomputer 1 and the system control one-chip microcomputer exchange data via a communication line 8, and when the user of the VTR set operates the keys on the front panel, key input information is transmitted. The one-chip microcomputer 1 for the timer determines the key, and the system control microcomputer 4 issues a command according to the contents of the key.
send to The system control microcomputer 4 determines how each slave block should operate based on the sent command, and based on this result, controls the slave blocks and determines the operation of the entire set.

Generally, timer reservation settings are performed by operating keys on the front panel and inputting data such as the reservation date, recording start time, end time, and recording channel number. The timer microcomputer 1 stores these input data on its internal RAM. The timer microcomputer l has a clock function and therefore always holds current time data. This current time data is compared with the timer reservation data, and commands such as start and end of recording are sent to the system control microcomputer 4 according to the timer operation, and the system control microcomputer controls the slave block to perform the actual operation. will be recorded.

Next, with reference to FIG. 2, a flowchart of a time change section in software of a VTR timer according to an embodiment of the present invention will be described.

The setting method for timer recording of consumer VTRs varies widely depending on the manufacturer and model, so a description thereof will be omitted here.

Also, in this example, it is timer reservation information. The recording date, start time, stop time, and channel are stored in the RAM of the one-chip microcomputer, and there is a mode to confirm the contents of the reserved program, and the time can be changed within this confirmation mode. Assumed to be performed.

When the reservation confirmation mode is selected by operating the VTR set, the timer will display the date and time of the reserved program.
Start and stop times.

The channel number etc. are displayed on the fluorescent display tube etc. on the Set. Next, the timer inside the microcomputer (hereinafter abbreviated as microcomputer) is cleared to 0.

This timer is used to indicate the elapsed time in the reservation confirmation mode, and may be configured by hardware or software, and is always incremented during the reservation confirmation mode.

Next, it is determined whether there is the key human power to change the time, which is the purpose of the present invention, and if the key human power is present, the time change routine is entered, and if not, the time change processing section is skipped. .

In the time change processing routine, first, the RAM in the microcomputer
The data held above and indicating the start time is incremented by an amount corresponding to 5 minutes. Next, by incrementing, for example, from 23:55 to 2 of the next day.
It is determined whether the date has been updated, such as when the date is changed to 4 o'clock, and if the date has been changed, the data indicating the date on the RAM is incremented by one day. Furthermore, for the stop time, the data is incremented for 5 minutes in the same way as for the start time.

As a result of this operation, the reservation time will be shifted by 5 minutes in response to the time change KEY input. After this, if there is another KEY input, the same operation is repeated. Furthermore, if there is no KEY input, the reservation confirmation mode ends after 5 seconds. Furthermore, when the reservation confirmation mode cancel key is input, the reservation confirmation mode is forcibly canceled.

In this embodiment, the reservation time is shifted in units of 5 minutes, and if there is no key input, the mode will be canceled in 5 seconds, but this value of 5 minutes or 5 seconds can be changed to any other value. Needless to say, value is also good.

In general, the program broadcast time is almost always shifted in units of 10 minutes or 5 minutes, and an appropriate unit shift amount is about 5 minutes.

According to this embodiment, for example, if the broadcast time of a reserved program is delayed by 20 minutes, after switching to reservation confirmation mode,
By pressing the time update key four times, the reservation details can be changed.

FIG. 3 is a flowchart of another embodiment of the invention. This example is basically exactly the same as the embodiment, but it adds a function to delay the reservation time and a process to advance it. Along with this, K E Y for time change is also +
, -2 shall be provided. With this configuration, if the key that delays the time is pressed too much by mistake, it can be corrected by pressing the key that advances the time.

〔Effect of the invention〕

As explained above, the invention requires some software and one KE compared to the conventional VTR timer software.
By simply adding Y, if the broadcast time of a reserved program is changed, the reservation contents can be changed by pressing one key, which has the effect of greatly improving usability for the user.
