Description

How to auto debug geocode data on VSI system

The present invention relates to the automatic debugging data of the CODE code in the VSI system having the CODE code receiving function, and in particular, it is possible to automatically check the CODE code data registered in the memory of such a system so that the set inspection of such a system can be performed. It is intended to be easy to implement.

G-Code is a simple reservation recording system developed by GEMSTAR of the United States, which allocates a number to a specific program to facilitate reservation recording. It is possible.

Such a code can be reserved by inputting a code that codes up to 8 digits of 4 data of channel, date, start time, and broadcasting length (C, D, T, L). After entering the code, select 'Weekly / Once / Month-Fri' and leave the remote control next to VSIal. When the scheduled time comes, IR will transmit the infrared and the VSI will start recording. It is compatible with each company's VSI, and there are VSI and TV with this function.

The PLUS CODE system was invented to summarize these four elements into separate numbers called plus codes, which are based on the geographic region, VCR PLUS and SHOW VIEW, respectively. It is called).

On the other hand, such a CODE has four elements needed to record a specific TV broadcast: date, channel, start time, and broadcast length. If you set the date as 31 days, 125 channel types, and the start time interval in 5 minutes a day, 288 (60/5 = 12, 12 * 24 = 288), and the length of the broadcast is 3 hours up to 5 minutes. There are 56 different intervals (5 minutes up to 3 hours, 15 minutes up to 3-8 hours). Thus, the total number of recordable cases is 31 × 125 × 288 × 56 = 62,496,000.

If the numbering is made irregular, approximately 5/6 will be 8 digits, and the remaining 1/6 will be 7 or less digits, an average of 7.8 digits. If you use this code as it is, it is inconvenient for consumers to use because it is 8 digits (1-8 digits).

So, this numbering must not be irregular to reduce the number of digits so long as possible. By giving priority to each element according to certain rules (combined into one element for T and L), and combining them according to the optimized bit scheme, the plus code is compressed by 100 times in a typical city, 5.5-6 Reduced to the size of the digit. Thus, the plus code is an optimized number system that represents a combination of C, D, T, and L.

Therefore, the more frequently used broadcasting program, the shorter digits are compressed and used as a zip code, and the compressed zip code is decoded and used again inside VSI.

There are two types of coding methods: the main system (main system) and the auxillary system (subsystem). The frequently recorded broadcast programs (shows, movies, sports, special features, dramas, educational programs, etc.) Broadcasting programs that use the system and record it occasionally are sub-systems. This subsystem is aimed at progress, information exchange, and decentralization. The main system goes through a more complex process than the subsystem, producing shorter code.

The main system consists of coding and decoding processes.

The coding process generates plus codes on four elements C, D, T, and L, and the decoding generates C, D, T, L on plus codes in the reverse order of coding. The coding process consists of two programs: GCODE.BAS and SCRAM5.BAS. Jamstar will license these two programs to registered companies, newspapers and magazines. These companies use it to create plus codes and put them in TV programs. The decoding process also consists of two programs: DECODE.BAS and DESCRAM5.BAS. Jamstar supplies these two programs to licensed VSI manufacturers who want to use them for microcomputers that control them.

In addition, the coding and decoding processes are as follows.

Coding:

C, D, T, L-(GCODE.BAS)-G-Code-(SCRAM5.BAS)-Plus-Code

Decode:

Plus-Code-(DESCRAM5.BAS)-G-Code-(DECODE.BAS)-C, D, T, L

In addition, the sub-system consists of IFCODE.BAS, one program for coding and scrambling, and IFDECODE.BAS, one program for descrambling and decoding.

Subsystem

Coding:

C, D, T, L-(IFCODE.BAS)-Pluscode

Decode:

PlusCode-(IFDECODE.BAS)-C, D, T, L

For VSI manufacturers, the technical challenge is to put DESCRAM5.BAS, DECODE.BAS, and IFDECODE.BAS into VSI microcomputers, which require about 2KBytes.

In addition, the system will be described in more detail as follows.

Main system

A. Coding and Decoding Process

a. Description of GCODE.BAS

The logic of the program is as follows.

Each TV program has four elements for recording: channel, date, start time, and broadcast length. Each element is first converted to a number representing the priority of those elements. The smaller the number, the higher the priority.

For example,

Channel: The smaller channel number has higher priority.

Date: equal priority

Start time: P.M. 7:00-P.M. In order of 6:00 (experimental, experience)

Broadcast Length: 1 hour-30 minutes

When four priority numbers are determined, these numbers are converted to binary numbers. For example, the channel priority number 0-255 is 8 bits, the date 1-31 is 5 bits, and the time and broadcast length are 14 bits. Bits converted from the four priority numbers are shuffled in a manner called bit hierarchy scramble. The 27 bits are combined to form a zip code.

b. SCRAM5.BAS

The scrambled code above is re-scrambled to produce 1-8 digits plus code in the newspaper.

c. DESCRAM5.BAS and GDECODE.BAS

These consist of the complete reversal of SCRAM5.BAS and GCODE.BAS.

In addition, a method of using a code set of the above scheme is as follows.

A. Press the CODE key to set the code set mode.

B. Set while looking at the code published in newspapers or magazines.

C. Press the PLUS key to release it. At this time, after the release, the program reverse (PGM REV) mode is displayed and the converted contents are displayed.

Real Ch. Must be set to the plus channel (currently based in Seoul) before setting the CODE.

On the other hand, VSI system related to such a CODE code is shown as shown in FIG.

Here, the microcomputer 31 for controlling the VSI system, the servo circuit 32 for driving control of the motor on the system deck side, the remote control unit 33a and the set side wirelessly connected to the remote control transmitter 33c A timer circuit 33 to which the key portion 33b is connected, and an audio circuit 35 for processing a reproduction or audio recording signal in the system are provided.

The system also includes a video circuit 37 for providing a recording signal to the tape side or processing a reproduction video signal from an RF signal provided from the tuner and the eye unit 38, and an audio signal at the time of double speed reproduction on the system deck side. A DMSS unit 36 for controlling to provide a steady state, an ODS unit 34 for generating an OSD screen, and a tuner for synchronizing a signal received from an antenna and generating a signal of an intermediate frequency And an eye F 38, a power circuit 39 for supplying a system power source, and the like.

In addition, the conventional system of the reservation recording method using KBP data in such a system is introduced in Korean Patent No. 1305 (Publication No. 94-16194).

In this case, when a user sees a program identifier displayed on a newspaper, etc., and inputs it as reserved recording data, the system checks whether the scheduled recording is set as shown in FIG. 4 and checks whether the scheduled recording is being executed if the scheduled recording is set. After that, the identification code is extracted to proceed with or end the reservation recording based on the start time, length, title, etc. of the program provided by the KBP signal data.

On the other hand, when manufacturing a set of VSI systems designed in the conventional geocode method as described above, the operator was performing debugging by looking at the text program provided by the geocode maker, and thus the hassle of debugging. It was difficult to avoid and inconvenience.

An object of the present invention is to save the code text program data in the VSI memory to improve the above problems and to conveniently perform debugging when the operator enters the code program, the convenience of such a set check operation The castle was to be obtained.

According to the present invention, the system stores the code table, the text program M and the geocode program MO, so that the system compares the M and the MO and determines that the geocode data matches if they match. It is a feature of the automatic automatic detection of geocode data in a VSI system which is executed by a geocode debugging processing program including a step of giving down and a case of inconsistency of judging the geocode data.

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

100. Automatic code data debugging program

In the BC system according to the present invention, the automatic method for debugging the CODE code of the BC system is illustrated in FIG. 4.

Here, the system stores the step by the operator's code table input (step 101), then stores the text program M input by the operator (step 102), and stores the geocode program MO again ( Step 103), and then the system compares M and MO, and if they match, outputting a determination that the geocode data matches on the OS screen (step 106); And the step of outputting the data (step 107).

In the present invention, a set operator stores code table values, text program values M, and geocode program MO values in VSI microcomputer or system memory, respectively, and compares the text program M and geocode program MO with M = Check the MO authorization.

When the comparison value does not match, it is found that there is a problem with the geocode data, and the operator needs to correct the geocode data.

On the other hand, the above operation is performed by the VSI microcomputer with the geocode debugging processing program 100 as shown in Figure 4, which stores the code table, the text program M and the geocode program MO input by the operator, After that, if the system compares M and MO and they match, the system determines that the geocode data matches and outputs it to the OS screen. If the discrepancy is inconsistent, the system determines the geocode data mismatch and outputs it to the OS screen. 107).

The present invention is such a set check operation by allowing the set maker to automatically compare and modify the Zcode text program stored in advance when the set maker examines the Zcode program stored in the memory of the set. It is possible to secure the ease of use.
