It is assumed that 16 areas or objects as shown in FIG. 6 are valid as areas to be subjected to Link information.

  Next, the operation of the reference example of the information reproducing apparatus will be described with reference to the flowchart of FIG. Now, when the reproduction program number is instructed to the CPU 12 (step 101 in FIG. 7), the reproduction of the recording medium 10 is started by the data reader 11, the side information is read and supplied to the side information analyzer 14, Is read from the recording medium 10 by the data reader 11 and supplied to the MPEG decoder 20 for decoding.

  The audio and video information data decoded by the MPEG decoder 20 is input to an image layout processor 18, converted into a predetermined display format, and supplied to a display 19. The display 19 displays and reproduces the audio and video of the program (step 102 in FIG. 7). The data output from the MPEG decoder 20 is also supplied to a reproduced image frame number manager 21, where the number of frames of the currently reproduced image from the start of the program is managed.

  When the user looks at the playback image displayed on the display 19 and plays back the WWW information, the user plays back the WWW information unique to the program, the WWW information unique to the index, or the WWW information unique to the object. Is determined and specified to the CPU 12 (steps 103, 104, 105, and 106 in FIG. 7). When WWW information is not reproduced, normal reproduction is performed as it is (step 107 in FIG. 7).

  When reproducing the WWW information unique to the program, the CPU 12 obtains the program number of the program being reproduced (step 108 in FIG. 7), and further obtains the program number of the program being reproduced analyzed by the side information analyzer 14. The WWW information (URL address information) of the PROG_IFO table shown in Table 2 is obtained (Step 109 in FIG. 7).

  Then, the CPU 12 supplies the input URL address information to the network processor 15. The network processor 15 connects to an external information site 16 indicated by the input URL address information via the Internet. Accordingly, when the content description information described in, for example, HTML (Hyper Text Markup Language) is transferred from the external information site 16 to the network processor 15, the network processor 15 transmits the content description information to the HTML processor. Transfer to 17.

  The HTML processor 17 performs HTML grammatical analysis on the input content description information, converts the obtained data into image data, and supplies the image data to the image layout processor 18. The image layout processor 18 fits the content description information image data obtained by processing the transmitted HTML information into a predetermined program information display format that is easy for the user to understand, lays out the image data, and sends the image data to the display 19. Is output and displayed (step 110 in FIG. 7).

  When reproducing the WWW information unique to the index (step 105 in FIG. 7), the CPU 12 obtains the frame number from the reproduced image frame number manager 21 (step 111 in FIG. 7). The index numbers in the INDEX_IFO table shown in Table 3 from FIG. 14 are obtained (step 112 in FIG. 7), and the WWW address information (URL address information) in the INDEX_IFO table obtained based on these is obtained (step in FIG. 7). 113).

  Then, based on the input URL address information, the CPU 12 connects to the external information site 16 indicated by the URL address information via the Internet via the network processor 15 as described above, and The content description information is converted into image data by an HTML processor 17, and the image data is supplied to an image layout processor 18. The image layout processor 18 embeds image data obtained by processing the HTML information transmitted from the external information site 16 into the image data of the program reproduced by the MPEG decoder 20, lays out the image data, and displays the image on the display 19. The data is output and displayed (step 110 in FIG. 7).

  When neither the program nor the index WWW information is reproduced, a mode for acquiring the WWW information unique to the object is entered (step 106 in FIG. 7), and the CPU 12 acquires the frame number from the reproduced image frame number manager 21. (Step 114 in FIG. 7). Here, the cursor position manager 22 of FIG. 1 displays a cursor that can be moved by the user on the image laid out by the image layout processor 18 and displayed on the display 19. The cursor position information is supplied to the cursor position manager 22 via the image layout processor 18.

  Therefore, the CPU 12 acquires the cursor position designated by the user in the current image from the cursor position manager 22 (step 115 in FIG. 7), and obtains the cursor position, the frame number, and the reproduction side information from Table 4 below. The object number in the indicated OBJECT_IFO table is obtained (step 116 in FIG. 7), and further, the WWW address information (URL address information) in the OBJECT_IFO table is obtained (step 117 in FIG. 7).

  Thereafter, in the same manner as described above, the image of the information provided from the external information site 16 based on the URL address information is inserted into the image data of the program reproduced by the MPEG decoder 20, laid out and displayed on the display unit 19. (Step 110 in FIG. 7).

  Next, the information recording method of the present invention will be described. FIG. 8 shows a block diagram of an embodiment of an information recording apparatus to which the information recording method according to the present invention is applied. The information recording apparatus according to the present embodiment is configured such that, during reproduction by the information reproducing apparatus, the user obtains information on a program or information on a specific program unit, information on a unit obtained by dividing the program into predetermined time sections, an image, This is a recording apparatus for recording and updating information for each predetermined portion of.

  In FIG. 8, audio and video information data corresponding to a program specified by the user by the CPU 32 is read from the recording medium 30 by the data reading / writing device 31 and input to the MPEG decoder 33. The recording medium 30 is a writable recording medium. The recording medium 30 records content data and side information in the format described with the playback device.

  Next, the operation of this embodiment will be described with reference to the flowchart of FIG. When a reproduction program number is designated by the user interface 38 to the CPU 32, reproduction is started (steps 201 and 202 in FIG. 9). At the time of this reproduction, the side information reproduced from the recording medium 10 by the data read / write unit 31 is supplied to the side information formatter 39, and the audio and video information data corresponding to the program of the program number designated by the user is converted into MPEG data. The data is supplied to the decoder 33 and decoded.

  The audio and video information data decoded by the MPEG decoder 33 is supplied to an image layout processor 34, where it is converted into a predetermined display format, and then input to a display 35 for display. The display 35 sounds an audio sound corresponding to the program specified by the user, and displays a video image.

  On the other hand, the data output from the MPEG decoder 33 is also supplied to the reproduced image frame number manager 36, where the number of frames of the currently reproduced image from the start of the program is managed. The cursor position manager 37 displays a cursor that can be moved by the user on the image laid out by the image layout processor 34 and displayed on the display 35. The cursor position information is supplied to the cursor position manager 37 via the image layout processor 34.

  The user determines whether or not to record WWW information while watching the reproduced image displayed on the display 35 (step 203 in FIG. 9), and if not, causes the program to be normally reproduced as it is (FIG. 9). In step 204), when recording, the user inputs URL address information of a site describing desired content description information from the user interface (U / I) 38 to the CPU 32 (step 205 in FIG. 9). The address information is supplied to the side information formatter 39.

  Then, whether to record the unique WWW information (URL address information) in the program, the unique WWW information (URL address information) in the index, or the unique WWW information (URL address information) in the object Is determined and designated to the CPU 32 (steps 206, 207, 208 in FIG. 9).

  When recording the WWW information (URL address information) unique to the program, the CPU 32 specifies the program based on the program number because the program number specified by the user has been input at the time of reproduction. Step 209 in FIG. 9).

  The side information formatter 39 writes the input WWW information (URL address information) in the PROG_IFO table shown in Table 2 in the side information of the specified program based on the information of the program unit from the CPU 32. Is created, and the side information is recorded as additional information data on the recording medium 30 through the data read / write unit 31 (step 210 in FIG. 9).

  If the program is to record unique WWW information (URL address information) in an index, which is information for each unit obtained by dividing the program into predetermined time sections (step 207 in FIG. 9), the CPU 32 controls the reproduction image frame number manager. The input frame number is acquired from step 36 (step 211 in FIG. 9), and the user inputs a point instruction signal on a screen corresponding to the in-point and out-point, and a scene (index) is obtained based on the information. To obtain an index number (step 212 in FIG. 9).

  The side information formatter 39 writes the side information format in which the input WWW information (URL address information) is written in the INDEX_IFO table shown in Table 3 in the side information based on the frame number and the index number from the CPU 32. It is created and the side information is recorded as additional information data on the recording medium 30 through the data read / write unit 31 (step 213 in FIG. 9).

  When recording index-specific WWW information (URL address information), which is information for each predetermined part of an image (step 208 in FIG. 9), the CPU 32 determines the frame number input from the reproduced image frame number manager 36. (Step 214 in FIG. 9), pauses the screen being reproduced, asks the user to position the cursor on the stopped image, and obtains the position information from the cursor position manager 37. (Step 215 in FIG. 9), which position on the screen is specified, and an object number is obtained from the specified cursor position (Step 216 in FIG. 9).

  The side information formatter 39 uses the OBJECT_IFO shown in Table 4 in the above-described side information based on the in-point and out-point information specified by the number of image frames from the CPU 32 and the screen position information specified by the cursor position. A side information format in which input WWW information (URL address information) is written in the table is created, and the side information is recorded as additional information data on the recording medium 30 through the data read / write unit 31 (step 217 in FIG. 9).

  Thus, in this reference example of the information reproducing apparatus, the reproduction information of the main part recorded on the recording medium and the content information obtained from accessible means other than the recording medium information are linked and displayed on the display. After recording the program data (program) on the recording medium by the user, the reproduction operation is performed by using the URL address information of the home page in which the information about the program is described. (I.e., at the user's arbitrary timing irrespective of the program playback during the program playback). That is, for example, when the user clicks on any image in an arbitrary scene during playback of the image and audio information of the movie program from the recording medium, information on the image is connected via the Internet separately from the movie program. URL address information can be obtained from an external information site and reproduced.

  Further, according to the present embodiment of the information recording apparatus to which the information recording method according to the present invention is applied, the user can re-record the latest information address, By specifying a specific scene or object or a part of the screen, URL address information (WWW information) from which an image of the description information can be obtained can be recorded.

  In the information recording device, the information of the program unit, the information of a specific program unit, or the information of each unit obtained by dividing the program into predetermined time sections, the in-point and the out-point specified by the number of image frames. Information, information on the basis of the additional information such as screen position information specified by the cursor position, URL address information corresponding to them, and information data, for example, from a broadcast to a radio wave or from a communication network are simultaneously input. In some cases.

  In this case, as shown in the block diagram of FIG. 10, the information serving as the base of the additional information and the URL address information are supplied to the side information formatter 39, where the side information format is created. Is recorded on the recording medium 52 through the data reader / writer 51 together with the information data obtained from the received radio wave or from the communication network while taking into account the recording time information and the like.

  In the above embodiment, an example is shown in which address information such as a URL is linked from side information recorded on a recording medium. However, the present invention is not limited to this. May be directly transmitted.
