Therefore, in the present embodiment, in addition to the effects of the first embodiment, the operation of the program instruction at the time of reproduction is further facilitated.
[0061]
(Embodiment 3)
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0062]
The same components as those described in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.
[0063]
FIG. 9 is a configuration diagram of a recording / reproducing apparatus according to the present embodiment. The main difference from the first embodiment is that the first directory generation unit 102 and the program recording information generation unit 100 are replaced by a The second point is that the second directory generation means 6 is used.
[0064]
Hereinafter, the configuration of the present embodiment will be described focusing on the second directory generation means 6.
[0065]
As shown in FIG. 9, the second directory generating means 6 as the table generating means of the present invention includes a recording address 213 of the recorded program program 5 on the optical disc 200 and a recorded program program corresponding to the recording address. This is a means for generating a correspondence relationship with the program number 4 (see FIG. 11) and outputting it as the second directory information 7 to the recording means 209. Here, the recording address 213 is an output from the address generation unit 212, and the program number 4 is an output from the program instruction unit 3. The second directory generating means 6 is constituted by a microcomputer or the like.
[0066]
Next, the operation of the present embodiment in the above configuration will be described with reference to FIGS. FIG. 10 shows the operation of the second directory generator 6, and FIG. 11 shows the second directory information 7 generated by the second directory generator 6.
[0067]
As shown in FIGS. 10 and 11, when a program having “10” as the program number 4 is recorded at the start address “10000”, the second directory generating unit 6 sets “10” as the program number 4 The first address “10000” is read from the instruction means 3 as the recording address 213 from the address generation means 212. Then, the second directory information 7 is recorded on the optical disc 200 via the recording unit 209. The same applies to the case of “11” and “20” as the program numbers 4 shown in FIG.
[0068]
That is, the recording unit 209 records the directory information 7 in a predetermined area of the optical disc 200, for example, a directory area on the inner circumference of the optical disc 200, and records the program 5 itself at a predetermined recording address. The directory information 7 generated in this manner directly associates the program number of the program included in the multiplexed information 1 with the recording address. Thus, similarly to the above-described embodiment, even when a large number of programs included in the multiplexed information 1 are recorded on the optical disc 200, the user can basically identify the program from the multiplexed information 1. By the same operation, the program can be easily identified from the optical disc 200. However, the present embodiment is different in that the configuration required to exhibit the same effect is simpler than that of the above embodiment.
[0069]
(Embodiment 4)
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0070]
The same components as those described in FIG. 9 are denoted by the same reference numerals, and description thereof will be omitted.
[0071]
FIG. 12 is a configuration diagram of a recording / reproducing apparatus according to the present embodiment. The main difference from the third embodiment is that the third directory generation unit 54 is replaced with the third directory generation unit 6. The difference is that the program guide information extracting means 52 as the extracting means of the present invention sends a part 53a (see FIGS. 3 and 14) of the program guide information to the third directory generating means 54. is there.
[0072]
Hereinafter, the configuration of the present embodiment will be described focusing on the third directory generation unit 54.
[0073]
As shown in FIG. 12, the program guide information extracting means 52 outputs the program guide information 53 to the display means 505 as in the case of the above embodiment, but outputs the program guide information 53 to the third directory generating means 54. In other words, it outputs a part 53a (see FIG. 3) of the program guide information. The third directory generating means 54 generates the correspondence (see FIG. 14) between the program number 4 of the program for which recording was instructed, the recording address 213 thereof, and the corresponding program guide information part 53a. , To the recording unit 209 as the third directory information 55.
[0074]
Next, the operation of the present embodiment in the above configuration will be described with reference to FIGS.
[0075]
FIG. 13 shows the operation of the third directory generating means 54, and FIG. 14 shows the third directory information 55 generated by the third directory generating means 54.
[0076]
In FIG. 13, the third directory generating means 54 reads the recording address 213 and also reads the program number 4 and a part 53a of the program guide information. Thereafter, the relationship between program number 4, recording address 213, and program guide information 53 is shown.ThirdIs generated.
[0077]
In FIG. 14, program guide information such as a program name and a program content is described corresponding to each of the recording addresses "10000", "12000",..., "50000". The recording unit 209 records the third directory information in a predetermined area, for example, a directory area of the optical disc 200, and records the program 5 at a recording address described in the third directory information 55.
[0078]
As described above, in the present embodiment, unlike the above embodiment, a part of the program guide information is recorded on the optical disc 200 in correspondence with the program number 4 and the like.
[0079]
Therefore, in the present embodiment, in addition to the effects of the above-described embodiment, the recording capacity can be further reduced as compared with the case where all the program guide information is recorded. This is very effective when the recorded program is to be stored for a long time, because the program guide information to be recorded is not wasted.
[0080]
Also, when recording the transmitted digital multiplexed information on a recording medium, the program guide information can be recorded corresponding to the recording address of each program in a directory on the recording medium. There is an advantage that a program can be selected using program guide information.
[0081]
(Embodiment 5)

In the figure, a multiplexed information separating means 2 is a means for separating a program designated by a user from the recorded multiplexed information 1, joining them together, and outputting them to a display means 505. The program instructing means 63 is means for instructing, on the screen of the display means 505, the program to be viewed when viewing the program program currently being broadcast, similarly to the above embodiment. This is a means for instructing a program to be reproduced from among the performed programs.
[0086]
The address generation unit 212 uses the date and time when the multiplexed information 1 was sent as the identification information of the multiplexed information 1 to be recorded. That is, the address generation unit 212 generates the date and time identification information 53c for distinguishing the date and time in units of one hour, and the recording address 213 (see FIG. 16) for each time of the multiplexed information 1, and the recording unit 209 Output. The date and time identification information 53c is output from the program guide information extraction means 52. The reproduction instructing means of the present invention corresponds to the program instructing means 63, and the reproducing means of the present invention includes the reproducing means 506 and the multiplexed information separating means 2 and the like.
[0087]
Next, the recording and reproducing operations of the present embodiment in the above configuration will be described.
[0088]
When there is a recording instruction from the user, all the multiplexed information 1 received by the receiving means 60 is recorded on the optical disc 200 via the recording means 209 in a multiplexed state. In this case, of course, all the counter programs are also recorded. The recording unit 209 records the program guide information 53 and the fourth directory generation information 62 together with the multiplexing information 1. FIG. 16 shows the fourth directory information 62 generated by the fourth directory generating means 61. According to FIG. 16, for example, it can be seen that the multiplexed information broadcast from 10:00 AM to 01:00 AM on January 1, 2000 is recorded with 10000 as the start address.
[0089]
The operation of reproducing the recorded program will be described.
[0090]
In response to a user's instruction for a reproducing operation, the reproducing means 506 reads out the program guide information 53 recorded on the optical disc 200 and sends it to the display means 505. The user 300 refers to the list of the program guide information displayed on the display unit 505, and instructs the program to be reproduced using the program instruction unit 63. The program instructing means 63 transmits the program number 4 corresponding to the instructed program to the multiplexed information separating means 2 and the reproducing program.Step506. Using the program number 4, the reproducing unit 506 checks the broadcast date and time of the program designated by the user from the program guide information, and uses the program guide information as the date and time identification information 53c. 4, a recording address 213 corresponding to the date and time identification information 53c is obtained. The reproducing means 506 reads out the recording information with the recording address 213 thus obtained as the head address, and sends it to the multiplexed information separating means 2. The multiplexed information separating means separates only the program corresponding to the program number 4 sent from the program instructing means 63 from the multiplexed information, connects them, and outputs them to the display means 505.
[0091]
As described above, in the present embodiment, in addition to the effects of the above-described embodiment, all programs are recorded as multiplexed information, so that counter-programs can be reproduced.
That is, when recording on the recording medium from the transmitted digital multiplexed information, the program guide information can be displayed collectively, and the program recorded on the recording medium can be selected from the information. For example, there is an advantage that a large amount of programs for one week are recorded, and the programs can be selected based on the transmitted program guide information. In the above embodiment, the case where the optical disc is used as the recording medium has been described. However, the present invention is not limited to this, and for example, other magnetic tapes or semiconductor memories may be used.
[0092]
Further, in the above-described embodiment, a case has been described in which, as the third directory information, a part 53a of the program guide information is generated as an integrated table of the program number 4 and the recording address 213 as shown in FIG. However, the present invention is not limited to this. For example, if the correspondence with the program number is known, the part 53a of the program guide information may be generated as an independent table.
[0093]
Also, the case has been described where the fourth directory information uses the broadcast date and time as the identification information. However, the present invention is not limited to this, and other identification information may be used.
[0094]
Further, in the above embodiment, when displaying the list of the program guide information, a case has been described in which a hatched pattern is further applied to distinguish recorded programs, but the present invention is not limited to this. Then, only the recorded program may be displayed.
[0095]
【The invention's effect】
As is apparent from the above description, the present invention has an advantage that, when a large number of program programs are recorded / reproduced on a recording medium, the recording / reproduction can be performed more easily than in the past.
