詳細情報も表示できる。FIG. 4 shows a procedure for executing a basic recording reservation according to the present invention. The present invention accesses a homepage in the information file 2 having information such as a program guide via the Internet. When a recording reservation operation is designated, as shown in FIG. 4A, the video recorder 4 of the present invention automatically accesses a homepage indicated by a preset URL address via the line 1 and displays a program guide on a screen. The amount of information displayed on the screen is limited. In order to reduce the amount of information transferred at one time, if a plurality of program tables are prepared for terrestrial broadcasting, satellite broadcasting, or genre, the program table is selected first. Next, by operating the remote controller or the operation panel, the cursor is positioned on an arbitrary program column and clicked to select a program. When recording reservation is instructed, the recording control information in the program guide is recognized and stored as recording reservation information.
When the display of the program details is instructed, the program details information is downloaded from the information file 2 storing the program details information and displayed on the screen. A recording reservation instruction can also be made from this screen. As in the case of the conventional video recorder, by operating the answering switch of the remote controller or the operation panel, the video recorder 4 is in a recording waiting state, and when a control code from a designated time or a teletext is received, recording is performed. To start. Detailed program information
Because it has the same format as the Internet homepage,
Since the image is created in a compression format such as JPEG or GIF and is much smaller than the content of the program, the recording medium 5 is not wasted. For example, in the case of an image of 200 × 150 dots, the required storage capacity is about 3 KB. When the recording is executed, as shown in FIG. 4B, the program is recorded in the program recording area of the recording medium 5, and after the recording is completed, the recording medium 5 is rewound to update the recording content information in the title area. According to the conventional method, only the date and time and the broadcast channel number are recorded and displayed as the recording content information. In the case of the present invention, the program name, the number of stories, the subtitle, and the like can be displayed. By doing so, the recorded program detailed information can also be displayed.

ル名を通知する必要はない。The video recorder 4 can execute the same operation as a general Internet browser in addition to a special operation for selecting a program column in order to display a general homepage. This switching of the operation method is performed using a comment sentence that is not displayed on the screen in the HTML language. FIG. 6 shows a description example of the program guide information. <! −− −−> is the comment sentence,
There are two ways of using the above-described operation method switching and recording control information description. <! The portion of --- info = video-> is a comment sentence for setting the operation mode of the program column selection, and only a page having this sentence is recognized as a program guide, and a general Internet browser attaches the program name to the page. A program guide is assembled from recording control information in which only information is listed. <! A comment line in which a numerical string is written as in −−99 is the recording control information, and is associated with the program column on the screen. When the program column is selected and the recording reservation button is clicked, the recording control information is set. It is memorized. Recording control information is provided in the program table so that detailed information of the program does not have to be read each time a recording is scheduled. However, if the number of programs to be displayed is large, it takes time to transfer data over the line 1. Therefore, it is necessary to make it compact. In this example, necessary information is packed and described so as to be 64 bytes or less per 15-minute program. The date is 2 digits in the year, but 10 when recording
A time lag exceeding 0 years does not occur, and is referred to at the time of reproduction and is not used for control. The drive code is a specific code corresponding to the control code from teletext, and the value of the control code for instructing the start of recording and the value of the control code for instructing the end of recording are compared with this code, and if the conditions match, the recording starts. Or end recording. The background color designation is for displaying the breaks in the program column in an easily understandable manner. The access to the detailed program information is based on the broadcast channel number,
Linking is possible by combining the date and time values, and there is no need to notify the video recorder 4 of the file name containing the detailed program information.
