A receiving device comprising: end instructing means for instructing a playback device to end a recording operation. (5) The transmitting side transmits TV program list information such as channel information, date information, time information, program code information, and title information using encoded transmission teletext, and the receiving side transmits the received TV program. In a system for making a recording reservation for an image recording and reproducing device using table information, the program number of a TV program list program by text broadcasting using the coded transmission method is fixed, and the channel information, date information, Time information, program code information, and title information are transmitted as code data, the channel information is a 2-byte system, and is the first character string in the first line of the main text, and the date information is 1
In the byte-based 2-character month data and 2-character day data, a symbol is inserted between the month data and the day data to separate both data, and the character string follows the channel information in the first line of the main text, and the time information is The start time information is required, and the end time information can be omitted. Start by inserting a symbol to distinguish between the hour data and minute data using 2 characters of 24-hour time data and 2 characters of minute data in a 1-byte system. Between the time information and the end time information, there is a character string with a symbol that distinguishes both pieces of information, and the program code information is immediately after the character string indicating the time information, with the foreground color being the same as the background color, and 2 bytes in 1-byte format. A transmission system characterized in that the title information is a character string between the character string immediately after the program code information and the time information character string of the next program. (6) Program numbers in TV program list information are fixed, program content update information, channel information, date information, time information,
means A for receiving teletext broadcasting using a coded transmission method to which program code information, title information, etc. are added as screen information; a third program recognition means for recognizing television program guide information from a fixed program number; a third program update recognition processing means for recognizing and processing an update of program guide information contents from the television program guide information detected by the third program recognition means;
a second channel information processing means for processing the channel information of the first character string in the first line of the text from the television program guide information detected by the program recognition means; and from the television program guide information detected by the third program recognition means. a second date information processing means for processing date information from the second character string of the first line of the text; and a second time information processing for processing time information from the television program guide information detected by the third program recognition means. means, a second program code information processing means for processing program code information from the television program guide information detected by the third program recognition means, and a title from the television program guide information detected by the third program recognition means. a second title information processing means for processing information; a third program update recognition processing means; a second channel information processing means; a second date information processing means; a second time information processing means; a display means for displaying on a screen the data processed by the program code information processing means and the second title information processing means; a cursor display means for displaying a cursor for each television program displayed by the display means; cursor moving means for moving the cursor displayed by the cursor display means for each program; selection means for selecting a recording reservation for the television program indicated by the cursor of the cursor display means; and a television selected by the selection means. a storage means for storing television program list information such as program channel information, date information, time information, program code information and title information; a timer means for time management; and a recording reservation program stored in the storage means. Comparison means for comparing the date information and time information with the date information and time information of the timer means; and the comparison means compares the date information and start time information of the recording reservation program with the date information and time information of the timer means.
