Description

European VSI System with Reservation Recording Update Registration

The present invention relates to a reservation recording means of VSI used in Europe, and more particularly, two reservation recording systems (Video Program System) and PD ( When the program arrangement registered by these systems is changed in the system environment in which Program Delivery Control is simultaneously operated, the program contents corresponding to the changed program number are executed in the changed program number so that the user can accurately execute the desired reservation. will be.

The VSI system has a program reservation recording function that automatically records the broadcast program time that you want to watch through a timer, G code, or V + (called PD / VPS in Europe).

For example, the prior art that is relatively related to the present invention is known in Korea Patent Publication No. 1223 Publication No. 94-6130 V-plus reservation recording means, which is shown as shown in FIG.

Here, a tuner circuit 2 for receiving a broadcast signal from the antenna 1, a broadcast station code detection circuit 4 for detecting a broadcast station code in a broadcast signal tuned from the tuner circuit 2, and a video recording processor 5 ), Reservation memory 11, OS 12, TV receiver 13, remote control transceiver 9, 8, key 10, and the like.

In such a system, the automatic setting menu screen of the V-plus guide channel as shown in FIG. 2 is shown through the OS unit 12, and the setting of the broadcasting station code versus guide channel is performed through this menu screen.

In this case, the OSD function is performed in the processing procedure as shown in FIG. 3, which means that the system tunes the channel of the minimum channel number of the channel tuned in the tuner circuit 2 (step 20) and checks whether there is a broadcast signal. (Step 21), it is checked if there is a broadcasting station code in the video signal (Step 22).

If there is a broadcasting station code, the corresponding guide channel corresponding to the broadcasting station code is matched to the channel currently tuned in (step 24). It is checked whether all channels have been tuned (step 25). If all channels are tuned, the guide channel is not set. A guide channel is manually set in the channel (step 29).

In step 25, when not all channels are tuned, only the channel number is pressed by 1 (step 28). If there is no broadcast signal in step 21, the OSD content of no broadcasting is set in the channel currently tuned in (step 27). .

If there is no broadcast station code, the guide channel is not set to the channel currently tuned in (step 26).

In such a system, a means of automatically setting a correspondence relationship between each channel to be tuned and a V plus guide channel using a V plus broadcast method is shown.

On the other hand, VSI is used in the conventional European region is known VPS and PD system which is a kind of V plus reservation recording method as described above.

First, the VPS method transmits a broadcast signal as shown in FIG. 2A by using line 16 of a TV image frame as a VPS data transmission unit during a vertical blanking interval (VBI) of a broadcast signal when a program is executed in a broadcast station.

At this time, the broadcasting station sends the program start time (month / day / hour / minute format) and status code to the broadcast signal when the program is executed. Since the program is recorded only when the start codes of are matched, it has the advantage of accurately recording only the desired program.

In addition, the PD system uses a tele-text line except for line 16 of the TV picture frame as a data transmitter during the vertical blanking interval (VBI) of the broadcast signal when the program is executed by the broadcasting station as shown in FIG. 2B. This system allows you to automatically record selected broadcast programs when you have the right equipment.

That is, when the user previews the teletext program guide page and selects a program that he / she wants to record using the remote control, the start time and end time of the program are precisely matched when the viewer's pre-selection and the transmitted program label match. It is recorded.

In addition, unlike the announcement of a broadcasting station, the above-described PD system enables the user to accurately record a program that the user wants to reserve recording even when the transmission time is different. Even when the program is restarted, recording can be continued again.

From the point of view of the broadcasting station, such a service has to be assigned the appropriate label with the program guide when making the first program schedule, and secondly, after the schedule is first announced and the new schedule is changed until the broadcast is released. It is necessary to change the program guide so that the broadcast schedule is changed to match the labels that will fly with the broadcast when the broadcast time arrives.

In the conventional VSI using the VPS and the PD system as the reserved recording method, after confirming the set contents after setting a plurality of reservation recording programs through the OSD menu screen, the registered contents are as follows. It was to give a mark.

Manual Search Program Type Broadcasting Station Schedule Recording System PR1 VPSPR2 PDCPR3 ... Next Screen Function Selection End

The user could check the program contents set by the user while viewing the screen as described above, and the user could freely change the arrangement of the program numbers.

However, conventionally, when changing the program number by viewing the program information displayed on the screen, the program number has been changed, but what is actually executed is a problem because the program is executed.

For example, if the user changes from Program 5 to Program 2 to transfer the contents of Program 5 to Program 2, the registered contents of Program 5 remain unchanged and the number remains changed. Because this is executed, the user wants to cause a problem such as running the program in duplicate.

The purpose of the present invention is to set up a reservation recording using such a system to improve the above problems, and when the program sequence registered by the user is changed, the contents of the registration can be changed along with the change of the program number. To avoid it.

In order to realize the purpose of the above-described example, the present invention, if the system has a program change, changes the program number and also changes the contents of the broadcasting station name, etc. And a tuner and broadcasting station code detection unit for receiving PD and VPS signals, and a video / audio processing unit for storing video and audio signals under the control of a microcomputer, and the like. It is characteristic of the SIAL system.

Hereinafter, more specific features of the present invention will be understood by describing the same in detail with the accompanying drawings.

That is, Figure 5 shows a circuit block diagram of a European VSI system having a reservation recording update registration function according to the present invention.

Here, if there is a program change in the system, the program number is changed as well as the contents of the broadcasting station, and the microcomputer 30 which automatically discriminates and processes the PD / VPS mode at the time of the scheduled recording, and the PD and VPS And a tuner and broadcast station code detectors 2 and 4 for receiving signals, and a video / audio processor 31 for storing video and audio signals under the control of the microcomputer 30.

Reference numeral 32 is a remote control input unit, 7 is an OSD unit, and VO is a video RF (RF) output signal.

The system is equipped with a reservation recording time data change processing program 100 as shown in FIG.

In this case, the system recognizes whether there is a program change and, if there is a change, updates the program number and broadcasting station name data, etc. to the numbered program, and thereafter, the process includes automatically determining and executing the PD / VPS when the reservation is executed. It's a process.

The reserved recording time data change processing program 100 has shown this in more detail.

In this case, the system checks whether there is a program change (step 101).

Then, the steps (steps 102 and 103) are executed to automatically determine the PD / VPS mode (step 104) and execute the reservation recording (step 105).

The present invention of such a configuration uses a number of PD / VPS system by using the VSI system to change the program sequence again when the contents of the manual search screen are registered in the memory. The registration content corresponding to the number before the change is automatically changed.

At this time, if there is a change in the reservation setting contents by the user as shown in FIGS. 5 and 6, the microcomputer 30 recognizes this and updates the changed number program contents registered in the memory with the changed number program contents. Change program contents will be deleted.

Therefore, if there is a code detection by PD or VPS method at a predetermined time through the tuner and broadcasting station code detection units 2 and 4, the micro computer 30 records the predetermined program through the deck unit if the code detection is performed. .

In addition, when the program changed in the system goes from PD to VPS program number, the scheduled recording by the PD method is automatically executed when the scheduled recording is executed.

On the other hand, the same operation is performed by the microcomputer 30 together with the reserved recording time data change processing program 100 as shown in FIG. 6, where the system checks whether there is a program change, and if so, changes the program number together with the program number. The execution registration contents are also changed, and the reservation / recording operation is automatically performed in the reservation execution process to execute the reservation recording (steps 101 to 105).

The present invention is to make a reservation or recording setting using the European VSI system and to change the arrangement of a plurality of programs registered at the time of executing a weak recording, the system automatically updates the registered contents and executes the PD or VPS when executing the scheduled recording. It can be recorded automatically and the user can implement the use of such a system conveniently without the user having to check the program number change.
