Description

Automatic disparity correction method using reservation recording system when transiting European countries to Europe

The present invention relates to a method for correcting a visual error of a set caused by a time difference between countries when moving between European countries for VSI, more specifically, a video recording system of a scheduled recording method for European VSI. And VSI for automatic correction of VSI set time error caused by the time difference between countries by automatically resetting the time of VSI set when moving between countries using Program Delivery Control system The present invention relates to a method for automatically correcting time lag using a reservation recording system when moving between countries.

VSI, which is conventionally used in Europe, has a high frequency modulator (1) for receiving and modulating a broadcast signal of a high frequency (RF) coming in through a high frequency input terminal through airwaves, and desired output from the output of the high frequency modulator. A tuner unit 3 for tuning a broadcast signal of a channel, an image IF detector 5 for detecting an intermediate frequency (IF) band of an image signal from the broadcast signal tuned by the tuner unit, a line input signal and an IF An input signal switching unit 7 for selecting and outputting a signal for each system operation mode and outputting a video signal and an audio signal separately from a line input signal or an image IF signal selected from the input signal switching unit as an output terminal; / Audio signal processing section 9, output signal switching section 11 for switching the output of the video / audio signal processing section to a line output terminal, and according to the key input state A control unit 15 for controlling the tuner tuning voltage, processing video / audio signals, and setting a reserved recording function, recording on a desired channel at a desired time, a decoder 13 for decoding a pay broadcasting signal, EPIROM 17, which is a memory means for storing reservation information, and the like, is provided.

If the power is turned off after the scheduled recording function is set in VSI, the VSI starts recording the reserved channel at the scheduled recording start time by the built-in timer, and the recording ends at the reserved ending time. If you start or end a program earlier or later than the time you want, or if another program, such as emergency news, is running in the middle of a program that is being broadcasted, the scheduled recording function is Since the start / end of the scheduled recording was executed based on the time of the VSI clock, there was a disadvantage that the above situation could not be coped with.

Therefore, to compensate for the above drawbacks, VPS and PDD systems have been developed as a reservation recording method in VSI, which is used in the conventional European region.

First, the VPS method transmits a broadcast signal using line 16 of a TV picture frame as a VPS data transmission unit during a vertical blanking interval (VBI) of a broadcast signal when a program is executed by a broadcasting 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.

The VPS system generally includes a data slicer for separating VPS data, a vertical sync signal (V-sync), and a horizontal sync signal (H-sync) from a composite video broadcast signal (CVBS), and the data slicer. A data line decoder for controlling the operation of the computer, interpreting / executing a command received in a 12C communication method with a microprocessor of VSIAL, and performing a data transfer, and reserves a VPS program from data received in the 12C communication method with the data line decoder. It comprises a control means for performing the recording function.

Meanwhile, the PD system transmits a broadcast signal using a tele-text line except for line 16 of a TV picture frame as a data transmitter during a vertical blanking interval (VBI) of a broadcast signal when a program is executed by a broadcast station. The PD system allows for automatic recording of selected broadcast programs when equipped with the proper 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, the user operates a command input unit to display the OSD screen to execute the scheduled recording, and the broadcast program is scheduled to be recorded on the OSD screen. If you set the type of broadcasting station, the station name and the reservation recording method (VPS or PD system) in advance, the control unit recognizes and remembers it. We could carry out normally.

In addition, the VSI system has a program for selecting an automatic time setting mode and automatically setting the time of each country when each country is set.

However, if the time difference occurs due to the movement of VSIs for Europe as described above, reservation recording may not be normally performed due to time difference. There was an inconvenience to reset the time of VSI system to eliminate by manual operation.

Therefore, the present invention has been created to solve the above problems, the present invention is able to automatically reset the time of the VSI set when moving between countries using the VPS and PD system generated by the time difference between countries The purpose of the present invention is to provide a time difference automatic correction method using a reservation recording system when moving between European countries to automatically correct visual errors.

In order to achieve the above object, the present invention provides a first step of determining whether a channel recognition signal (ID) is received by periodically receiving a broadcast signal input to a modulator in a power-off mode; If the determination result of the first step, if there is a channel ID, and outputs the data of the channel ID for each country, the second step of resetting the time of the corresponding country by detecting the channel ID of the country of each channel ID, characterized in that To provide automatic disparity correction method using reservation recording system when transiting VSIs to Europe.

Hereinafter, an automatic disparity correction method using a reservation recording system when moving between European countries in accordance with the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is an operation flowchart illustrating a method for automatically correcting time difference using a reservation recording system when moving between European countries in accordance with the present invention. As shown in FIG. 1, the first step is performed when the power is turned off. In step S11-S13, it is determined whether a predetermined time is reached by starting a time count, and determining whether there is a channel recognition signal ID in operation (S14-S16), and if the channel ID exists, Outputting the data of the ID and storing for each country (S17), the second step is to detect and compare the channel ID of the country of each channel ID (S18-S20) and the current time of the country It is shown that it consists of the steps (S21-S23) to calculate and reset to a time error value.

The operation of the present invention as described above is as follows.

First, when the power-off mode of VSI is set (Y branch of S11), the microprocessor 15 immediately counts the time (S12) and enters the high frequency modulator 1 when it is arbitrarily designated time (Y branch of S113). The broadcast signal is periodically received through the tuner view 3 and the image IF detector 5, and therefore, the decoder 13 receives each channel through the image IF detector 5 and the input signal switch 7. Identification data is detected and the data is output to the microprocessor 15.

In response, the microprocessor 15 stores the output data of the decoder in YPIROM 17 for each country.

Thereafter, the microprocessor 15 detects a channel ID corresponding to the corresponding country among the channel IDs after searching for a channel and resets the time of each country by calculating the time difference of the corresponding country based on the data stored in the ypyrom 17. Thus, the time difference of each country can be automatically corrected when moving between countries.

According to the present invention as described above, when the movement between countries in Europe for VSI, it is possible to automatically reset the time difference of each country by using VPS and PD system so that the time of VSI set generated by the time difference between countries The advantage is that the error can be corrected automatically.
