System for carrying out programmed recording

Abstract: A compact apparatus for carrying out a programmed recording is disclosed. Teletext data detected by a teletext circuit section (13) of a TV (10) is used as a programmed recording information, so that a programmed recording can be carried out in a simple and exact manner even without installing a teletext circuit section within a magnetic recording/reproducing apparatus (20). By utilizing a teletext function, a channel information stored in the magnetic recording/reproducing apparatus (20) is compared with a channel information of a programmed recording information received through a scart jack (30). If the channel information is same as the channel information stored within the magnetic recording/reproducing apparatus (20), then the programmed recording is carried out, and if it is not same as the latter, the user inputs the channel, thereby carrying out a programmed recording based on the received programmed recording information in a simple manner.

Description: BACKGROUND OF THE INVENTION 1. Field of the invention The present invention relates to a system for carrying out a programmed recording in which by utilizing a teletext function, a channel information stored in a magnetic recording/reproducing apparatus is compared with a channel information of a programmed recording information received through a jack, thereby carrying out a programmed recording based on the received programmed recording information in a simple manner. 2. Description of the related art Generally, when a user wants to carry out a programmed recording, broadcast signals having teletext data within a VBI (vertical blank interface) are received. By utilizing a teletext circuit section, only teletext data are detected from among the received broadcast signals, and a magnetic recording/reproducing apparatus outputs the detected teletext data to a TV screen. Then if the outputted data, i.e., the data to undergo a programmed recording is selected, then the appointed time and the channel for the selected program are stored. Then at the appointed time, the programmed recording is carried out by receiving the broadcast signals of the relevant channel through a broadcast receiving section. However, in carrying out the programmed recording by receiving the broadcast signals through an antenna, if the programmed recording is to be carried out in a convenient manner by utilizing the teletext function, a teletext circuit section has to be installed even within the magnetic recording/reproducing apparatus, this being a disadvantage US 5,390,027 discloses a television program recording and reproducing system in which television program information contained in an extracted text broadcast signal is selected and input to a video cassette recording device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 is a block diagram showing the constitution of the system for carrying out a programmed recording according to the present invention. As shown in this drawing, the system for carrying out a programmed recording according to the present invention includes: a TV receiver 10 for outputting a programmed recording information for a selected program selected from among teletext data of received broadcast signals (received through an antenna) in accordance with the intention of the user; a magnetic recording/reproducing apparatus 20 for storing the programmed recording information of the TV receiver, and for executing the programmed recording based on the programmed recording information; and a jack 30 for connecting the TV receiver and the magnetic recording/reproducing apparatus together to receive and transmit the programmed recording information and OSD messages. The TV receiver 10 includes: a broadcast receiving section 11 for receiving broadcast signals including teletext data; a teletext circuit section 13 for detecting teletext data from among the broadcast signals of the broadcast receiving section 11; a microcomputer 15 for controlling the total system in response to the key signals of a user; a channel memory section 17 for storing a channel (selected by the user) in response to the control signals of the microcomputer 15; and an input selecting section 19 for outputting the output signals of the broadcast receiving section 11 or external signals in response to the control signals of the microcomputer 15. The magnetic recording/reproducing apparatus 20 includes: a microcomputer 21 for controlling the total system of the magnetic recording/reproducing apparatus in response to the control signals of the microcomputer 15 of the TV receiver 10; a channel memory section 23 for storing the channel set by the user in response to the control signals of the microcomputer 21; a broadcast receiving section 25 for receiving broadcast signals of the relevant channel in response to the control signals of the microcomputer 21; an OSD generating section 27 for generating an OSD in response to the control signals of the microcomputer 21 after the microcomputer 21 compares the transmitted channel of the TV receiver with the stored channel of the channel memory section 23; and a jack control section 29 for controlling the jack 30 so as to output an OSD message through the input selecting section 19 of the TV receiver 10 to the TV screen in response to the control signals of the microcomputer 21. The system of the present invention constituted as above will now be described as to its operation referring to FIGs. 2, 3 and 4. FIG. 2 is a flow chart showing the programmed recording operation of the TV receiver of FIG. 1. FIG. 3 is a flow chart showing the programmed recording operation of the magnetic recording/reproducing apparatus of FIG. 1. FIG. 4a illustrates a picture state showing teletext data in TV. FIG. 4b illustrates an OSD message notifying the completion of the programmed recording. FIG. 4c illustrates the picture state of the OSD message in which the channel selection data for the programmed recording are entered. First, the user turns on the TV receiver 10 and the magnetic recording/reproducing apparatus 20 (S210 and S310). As shown in FIG. 2, if a key signal is inputted for displaying the teletext data on the screen (S215), then the microcomputer 15 outputs control signals to the teletext circuit section 13 in response to the key signal. Then only the teletext data from among the broadcast signals of the broadcast receiving section 11 are detected so as to be displayed on the TV screen (S220) (refer to FIG. 4a). In order to select the program to be recorded, while watching the teletext data on the TV screen, the user places the cursor on the relevant program, and presses a program selecting key (S225). Then the microcomputer 15 recognizes the key signal, and stores the relevant channel of the selected program into the channel memory section 17. Further, the set programmed recording information, i.e., the appointed time, the channel, the name of the program and the like are transmitted through 10th pin of the jack 30 to the microcomputer 21 of the magnetic recording/reproducing apparatus 20 (S230). In this context, the channel data may be different between the TV receiver and the magnetic recording/reproducing apparatus, and therefore, they are transmitted with the standardized code. As shown in FIG. 3, when there is a programmed recording (S315), its information is stored into an internal memory of the microcomputer 21. The channel data is subjected to a comparison to check as to whether there is the same code as the transmitted code within the channel memory section (S320). If there is the same channel (S325), the broadcast receiving section 25 receives the relevant channel at the appointed time in accordance with the control signals of the microcomputer 21, thereby carrying out the programmed recording (S330). Then in response to the control signals of the microcomputer 21, the jack control section 29 controls the . jack 30, so that an OSD message for notifying the completion of the programmed recording can be outputted through an 8th pin of the jack 30 to the input selecting section 19 (S335). Then the input selecting section 19 outputs an OSD message through the jack 30 to the TV screen in response to the control signals of the microcomputer 15 (S240), so that the user can watch it (refer to FIG. 4b) If the channel information of the programmed recording information is not same as the channel stored within the channel memory section 23 (S325), then the microcomputer 21 outputs the data of FIG. 4c through the OSD generating section 27 and through the jack 30 to the TV screen (S340). Then if the user inputs a key signal to correct the channel (S245), the microcomputer 15 of the TV receiver 10 transfers it through the jack 30 to the microcomputer 21 of the magnetic recording/reproducing apparatus 20. Then if the microcomputer 21 receives the corrected channel signals (S345), then the received channel is stored into the channel memory section 23, so that the programmed recording can be carried out at the appointed time (S330). Then a completion OSD message is outputted to the TV screen (S340). The above described steps are repeated until a programmed recording releasing signal is inputted by the user (S255). According to the present invention as described above, in carrying out a programmed recording, the teletext circuit section of the TV receiver is used without installing a teletext circuit section within the magnetic recording/reproducing apparatus. Therefore, the cost of the magnetic recording /reproducing apparatus is lowered, and the user can carry out the programmed recording in a simple manner.
