At this time, the program information updating means 291 recognizes the broadcast station of the acquired EPG and updates the program basic information 430 of the broadcast station information 420 corresponding to this broadcast station. And turn A signal indicating that the set information table 400 has been updated is output to the program information management means 293.

[0064] The program information search means 292 reads a keyword preset and input by the user. Then, program basic information 430 having a keyword is searched and acquired from the program information table 400. At this time, the program information search means 292 searches for each piece of information recorded in a text format such as program title information 434, program subtitle information 435, program genre information 436, and program description information 437. To see if there is a phrase that matches the keyword.

[0065] Also, the program information search means 292 refers to the recording reservation information list 500 and refers to the recording program title related word information 539, the recorded program subtitle related word information 540 of the reservation basic information 530, and the recorded program description related words. Read keyword related words described in information 541. Then, program basic information 430 having these keyword-related words is searched and acquired from the program information table 400. At this time, the program information search means 292 searches the program title information 434 using the keyword-related words described in the recorded program title-related word information 539, and searches for the keyword-related words described in the recorded program subtitle related word information 540. Is used to search the program subtitle information 435, and the program description information 437 is searched using the keyword-related words described in the recorded program description-related word information 541.

The program information management unit 293 generates reservation information 520 based on the program basic information 420 detected by the program information search unit 292, and performs a process of listing it in the recording reservation information list 500. That is, the program information management means 293 generates the recording basic information 521 based on the program basic information 420, and sets the automatic recording reservation flag 522 to “1” indicating that the automatic recording is reserved, and generates the reservation information 520. I do. Further, the program information management means 294B performs a process of incorporating the generated reservation information 520 into the recording reservation information list 500, that is, recording the information in the area of the memory 280 where the recording reservation information list 500 is stored. Further, the program information management means 293 sets information for manually specifying a program to be recorded, such as information indicating that the program is to be manually entered at the time of setting input and a program I / F blue report 421 for specifying a TV broadcast program to be recorded. In the case where the request information includes the information to that effect, the program basic information 420 corresponding to the information specifying the program is acquired from the program information table 400, and the reservation information 520 is generated. The reservation information 520 to be generated has an automatic recording reservation flag 522 that is manually recorded. Is set to "0". Then, as in the case of the automatic recording reservation, a process of incorporating the program into the recording reservation information list 500 is performed.

When the program information management unit 293 recognizes that the program information table 400 has been updated by the program information update unit, the program information management unit 293 stores the program basic information 430 acquired by the program information search unit 292 and the recording reservation information list. Compare with 500. Then, the program information management means 293 stores the program reservation information 510 recorded in the recording reservation information list 500 and the corresponding program basic information 4 30 in the program basic information 430 of the updated program information table 400. Determine whether or not. More specifically, the program information management means 293 first reads broadcast time information such as the recording start time information 533 and the recording end time information 534 of the reservation basic information 530 and the recording channel information 532, and It is determined whether or not there is program basic information 430 having the same broadcast time and channel information as the broadcast time and channel information. Furthermore, the program information management means 293 reads information related to the contents of the program in a text format, such as recorded program title information 535, recorded program subtitle information 536, recorded program genre information 537, and recorded program description information 538. Then, the contents described therein and the information on the program contents in text format such as the program title information 434, the program subtitle information 435, the program genre information 436, and the program description information 437 of the program basic information 430 are matched. Judge whether to do.

Here, the program information management unit 293 determines that the program basic information 430 corresponding to the recording reservation information 510 has been recorded in the program information table 400, The following processing is performed for the lost program information). That is, the program information management means 293 sends the program information search means 292 the recorded program title related word information 539, the recorded program subtitle related word information 540, and the recorded program description of the lost program information described in the recording reservation information list 500. The program basic information 430 including the keyword related words recorded in the related word information 541 is searched from the program information table 400. At this time, the program information management means 293 sends the program related information to the program basic information 430 which is the same broadcast station information 420 in the vicinity where the lost program information was scheduled to be broadcast, by the program information search means 292. To search sequentially.

When the program basic information 430 including the keyword-related word is searched, The set basic information 430 is determined to be lost program information. Further, when a plurality of program basic information 430 including keyword-related words are searched, the program information management unit 293 specifies one of the plurality of program basic information 430 based on a predetermined priority criterion, Judge as lost program information. At this time, the program information management means 293 specifies the program basic information 430 on the basis of V, for example, based on the following priority criteria.

[0070] That is, the program information management means 293 specifies the program basic information 430 by comparing the broadcast time frame and the broadcast time between the lost program information and the program basic information 430. Specifically, the program information management means 293 includes recording start time information 533 and recording end time information 534 of the lost program information, and program start time information 432 and program end time information 433 of the searched basic program information 430. And.

Here, when there is program basic information 430 having the same program start time information 432 and program end time information 433 as the recording start time information 533 and the recording end time information 534, the program basic information 430 has the highest priority. Then, it is determined as lost program information. Further, the program information management means 293 gives priority next to the program basic information 430 whose program start time information 432 is the same as the recording start time information 533 and whose program end time information 433 is different from the recording end time information 534. Judge as lost program information. Furthermore, the program information management means 293 gives priority to the program basic information 430 having the same broadcast time frame as the lost program information although the program start time information 432 is different from the recording start time information 533. to decide. Here, the broadcast time frame is the time from the time described in the program start time information 432 to the time described in the program end time information 433, or the time from the time described in the recording start time information 533 to the recording end time information. It means the time until the time described in 534. Finally, the program information management means 293 determines the program basic information 430 having the different broadcast time frame from the program start time information 432 different from the recording start time information 533 as the lost program information with the lowest priority.

[0072] Then, the program information management means 293 determines whether or not the program basic information 430 is further specified by the keyword-related words included in the program basic information 430 whose priority order is determined as described above. The priority order is determined. For example, the priority of program basic information 430 having similar title names! Second, the title names are different but the subtitle names are similar. The program basic information 430 is given priority. Finally, the program basic information 430 having different title names and subtitle names but similar program description information is given priority. Specifically, the program information management means 293 includes the recorded program title related word information 539 of the lost program information, the recorded program subtitle related word information 540, the recorded program description related word information 541, and the program basic information 430. The title information 434, the program subtitle information 435, and the program description information 437 are compared. When the program title information 434 includes the recorded program title related word information 539, the program information management means 293 determines that the title names are similar. Similarly, when the program subtitle information 435 includes the recorded program subtitle related word information 540, it is determined that the subtitle names are similar! / ヽ, and the recorded program description related word information 541 is included in the program description information 437. If it is included, it is determined that the program description information is similar.

[0073] Here, the power in which the priority is set as described above is not limited to this. Further, the conditions for determining the priority order may be edited by the user by setting and inputting.

Further, the program information management means 293 overwrites the lost program information recorded on the recording reservation information list 500 with the program basic information 430 searched for by the keyword-related word. At this time, the recorded program title related word information 539, the recorded program subtitle related word information 540, and the recorded program description related word information 541 of the lost program information are not deleted and are retained as they are. Then, the program information management means 293 inputs the basic program information 430 to the program information analysis means 294 to newly extract a keyword-related word, and newly extracts the extracted keyword-related word into the recorded program title-related word information 539, Recorded in addition to subtitle related word information 540 and recorded program description related word information 541.

Further, the program information management means 293 rearranges the recording reservation information 510 recorded in the recording reservation information list 500 in, for example, the order of the start time. For example, when the user manually sets and inputs the recording reservation information 510, the program information management unit 293 recognizes the recording start time information 533 of the recording reservation information 510, and Perform the sorting process.

[0076] The program information analysis means 294 analyzes the program basic information 430 input from the program information management means 293, and extracts keyword-related words. Specifically, the program information analysis means 29 4 analyzes the program title information 434, program subtitle information 435, program description information 437, etc. of the input basic program information 430, and divides the words and phrases included in each information into words to determine keyword-related words. Extract. Here, a keyword-related word obtained by dividing the title name described in the program title information 434 into words is recorded as recorded program title-related word information 439. Also, keyword-related words obtained by dividing the subtitle names described in the program subtitle information 435 are recorded in the recorded program subtitle-related word information 540. Further, keyword related words obtained by dividing the description information described in the program description information 437 into words are recorded in the recorded program description related word information 541.

[0077] The recording control means 295 controls the operations of the NIM 211, Demux 220, recording unit 251 and the like, and stores the partial TS of the desired broadcast program in the HDD 270 so that it can be read as appropriate. Specifically, based on an operation signal input from the input means 260, the information which requests that the partial TS of the desired broadcast program be recorded in the HDD 270 is recognized. Further, it recognizes the recording reservation information 510 of the recording reservation information list 500, and records a partial TS based on the recording reservation information 510.

The playback control means 296 controls the operations of the Demux 220, ADec231, VDec232, DDec233, the playback unit 252, etc., and outputs a desired partial TS to the output device 300.

[0079] The clock unit 297 recognizes the current time based on a reference pulse such as an internal clock.

[0080] Examples of the output device 300 include a personal computer, a television, a mobile phone, and a PDA (Personal Digital Assistant). The output device 300 receives and outputs content data input from the recording / reproducing device 10. The output device 300 includes a sound output unit 310, a display unit 320, and the like.

[0081] The audio output unit 310 has a sound generator such as a speaker (not shown). The audio output unit 310 outputs audio data described in the demodulated audio signal input from the ADec 231 by audio from the sound generation unit.

The display unit 320 includes, for example, a liquid crystal or an organic EL (Electro Luminescence) panel, a PDP (Plas ma Display Panel), CRT (Cathode-Ray Tube) and the like are used.

[Operation of recording and playback system]

Next, the operation of the recording / reproducing system 100 will be described with reference to the drawings. FIG. 6 is a flowchart showing a recording reservation process by a user's manual input. FIG. 7 is a flowchart showing automatic recording reservation processing by the CPU.

[0084] {Recording reservation processing of broadcast program}

(Manual processing of recording reservation)

First, a recording reservation process led by a broadcast program will be described with reference to FIG. First, the CPU 290 of the recording / reproducing apparatus 10 recognizes the reservation basic information 530 of the broadcast program desired by the user by a setting operation of a remote controller (not shown) by the user (step S1).

01).

At this time, as information set and input by the user, for example, program start time information 432, program end time information 433, and broadcast station information 420 are input. Alternatively, only program HD information 431 such as a G code for identifying a broadcast number may be input.

[0085] Then, the CPU 290 sets the automatic recording reservation flag information to, for example, 0 (step S1).

02), the recording reservation information 510 is generated in addition to the reservation basic information 530 manually set and input by the user (step S103).

[0086] Thereafter, the program information management means 293 of the CPU 290 records the recording reservation information 510 in the recording reservation information list 500. Then, the program information management means 293 recognizes the recording start time information 533 of the recording reservation information 510, sorts the recording reservation information 510 in order of the start time of the broadcast program, and updates the recording reservation information list 500 ( Step S104).

(Automatic processing of recording reservation)

Next, recording reservation processing by the CPU 290 will be described with reference to FIG. First, the recording / reproducing apparatus 10 outputs a TS data packet received by the NIM 211 to the DDec233, and obtains an EPG from the data packet by the DDec233 (step S110).

Next, the program information updating means 291 of the CPU 290 extracts the acquired EPG power, the broadcast station information 420, the program basic information 430, and the like. Then, the broadcast station information 420, the program basic information 430, the broadcast station information 420 and the program basic information recorded in the program information table 400 are stored. If the acquired program basic information 430 is updated by comparing with the information 430, the program information table 400 is updated by overwriting the program basic information 430 (step S111).

[0088] Then, the program information management means 293 of the CPU 290 recognizes the program information table 400 updated in step S111. Next, the program information management means 293 recognizes a keyword that has been set and input by the user in advance and recorded (step S112). Thereafter, the program information management means 293 causes the program information search means 292 to search the program information table 400 for the program basic information 430 having the acquired keyword (step S113).

In step S113, when the program information having the keyword is not searched, the program information management unit 293 checks for missing program information without performing the recording process of the new recording reservation information 510. Processing is performed (step S120).

On the other hand, when the program information having the keyword is searched in step S113, the program information management unit 293 first recognizes the recording reservation information list 500 recorded on the HDD 270 (step S114). At this time, the program information management means 293 recognizes the information of the automatic recording reservation flag information 520 and recognizes only the recording reservation information 510 set by the automatic input of the CPU 290. Then, of the program basic information 430 retrieved in step S113, it is checked whether or not the program basic information 430 recorded in the recording reservation information list 500 has a certain power (step S115).

[0091] In step S115, if all the program basic information 430 retrieved in step S113 is recorded in the recording reservation information list 500, the process of recording the new recording reservation information 510 is not performed, and the lost program information is omitted. The presence / absence is checked (step S120).

[0092] On the other hand, in step S115, of the program basic information 430 searched in step S113, the program basic information 430 not recorded in the recording reservation information list 500 (hereinafter, this program basic information is referred to as a new program in particular). If there is basic information), a process of recording this new program basic information as new recording reservation information 510 in the recording reservation information list 500 is performed. To do this, the program information management means 293 first causes the program information analysis means 294 to analyze the new program basic information, and extracts keyword-related words from the new program basic information (step S116). Specifically, the program information analysis means 294 determines whether the input new program basic Recognize text format data such as information program title information 434, program subtitle information 435, and program description information 437. Then, the words included in these pieces of information are divided into word units to extract keyword-related words. Here, the program information analysis means 294 uses the keyword-related words extracted from the program title information 434 as the recorded program title-related word information 539 and the keyword-related words extracted from the program subtitle information 435 into the recorded program subtitle-related word information. As 540, the keyword-related words extracted from the program description information 437 are recorded as recorded program description-related word information 541.

[0093] Then, the program information management means 293 stores the recorded program title related word information 539, the recorded program subtitle related word information 540, and the recorded program description related word information 541 acquired by the program information analysis means 294 in the new program basic information. Then, basic reservation information 530 is generated (step S117). Also, the program information management means 293 sets a value indicating that the information is the recording reservation information by the automatic reservation processing by the CPU 290, for example, “1” in the automatic recording reservation flag information 520 (step S118).

[0094] Thereafter, the program information management means 293 generates the recording reservation information 510 by combining the basic reservation information 530 and the automatic recording reservation flag information 520, and records it in the recording reservation information list 500 (step S 119). Further, when recording the recording reservation information 510 in the recording reservation information list 500, the program information management means 293 rearranges the recording reservation information 510 in order of the scheduled recording start time of the broadcast program.

[0095] Next, in step S120, the program information management means 293 of the CPU 290 performs a process of checking whether or not there is lost program information. Specifically, the program information management means 293 first reads the recording reservation information list 500. Then, the program information search means 292 is caused to search the program information table 400 for program basic information 430 corresponding to each piece of recording reservation information 510. If no program basic information 430 having the same content as the recording reservation information 510 is found in the program information table 400, the recording reservation information 510 is set as lost recording information.

Here, when there is no lost program information !, that is, when program basic information 430 having the same content as all the recording reservation information 510 recorded in the recording reservation information list 500 exists in the program information table 400 Then, the automatic recording process ends.

On the other hand, if there is lost program information, that is, at least one If the program basic information 430 having one content does not exist in the program information table 400, a process for specifying the program basic information 430 that has become lost program information is performed.

[0098] For this, first, the program information management means 293 converts the recording program title related word information 539, the recording reservation subtitle related word information 442, and the recorded program description related word information 541 from the reservation basic information 530 of the lost program information. Are read and the keyword-related words described in these are read (step S121). Then, the program information management means 293 causes the program information search means 292 to search the program information table 400 for program basic information 430 having a keyword-related word (step S122).

[0099] In step S122, when the program basic information 430 that has become lost program information cannot be specified, that is, the program basic information 430 having a keyword-related word does not exist in the program information table 400. In this case, the program information management means 293 deletes the lost program information from the recording reservation information list 500 and terminates the automatic reservation processing.

[0100] On the other hand, if the program basic information 430 that has become lost program information has been identified in step S122, that is, if the program basic information 430 having keyword-related words exists in the program information table 400, the program The information management means 293 specifies the program basic information 430 having the keyword-related word as the program basic information 430 that has become lost program information. When there are a plurality of pieces of program basic information 430 having keyword-related words, the program information management unit 293 assigns priorities to these pieces of program basic information 430, and the program with the higher priority is the lost program information. Specify as program basic information. The priority order includes, for example, the broadcast time, the broadcast time frame, the type of information including a keyword-related word (for example, program title information, program subtitle information, and program description information), and the included keyword-related information. It is set by the number of words.

[0101] Then, the program information management means 293 causes the program information analysis means 294 to analyze the program basic information 430 specified as the lost program information. The program information analysis means 294 reads textual information such as the program title information 434, the program subtitle information 435, and the program description information 437 of the program basic information 430, and decomposes the described words into words. Then, a new keyword-related word is extracted (step S123).

[0102] Thereafter, the program information management means 293 executes the keyword-related term extracted in step S123. Is added to the recorded program title related word information 539, the recorded program subtitle related word information 540, and the recorded program description related word information 541 of the lost program information. At this time, the keyword-related words previously recorded in the recorded program title-related word information 539, the recorded program subtitle-related word information 540, and the recorded program description-related word information 541 are left without being deleted. . Then, other information of the lost program information, that is, recording key word information 531, recording channel information 532, recording start time information 533, recording end time information 534, recorded program title information 535, recorded program subtitle information 536, recorded program jan The program information 537, the recorded program description information 538, and the like are changed based on the specified program basic information 430, and the recording reservation information 510 is overwritten (step S124). Further, the program information management means 293 records the overwritten recording reservation information 510 in the recording reservation information list 500, and sorts the recording reservation start time in order of earliest.

[Operation and Effect of Recording / Reproducing Apparatus]

In the recording / reproducing apparatus as described above, the program information management unit 293 receives the input indicating that the program information table 400 has been updated based on the EPG newly acquired by the program information updating unit 291 and receives the lost program. Determine if there is any information. Here, if there is lost program information, the program basic information 430 having the same content as the keyword-related word extracted by the program information analysis means 294 is updated from the updated program information table 400. This information is identified as 430. Therefore, even if there is lost program information, the lost program information is not immediately deleted. Therefore, it is possible to prevent a recording error of a broadcast program due to erasure of the lost program information. Conventionally, when the lost program information was deleted, it was necessary to make a recording reservation by the user's manual setting input. However, the program information management means 293 converts the lost program information into the program basic information 430 based on the keyword-related words. Since this program information is automatically recorded in the recording reservation information list 500, it is possible to acquire an appropriate broadcast program and make a recording reservation.

The reservation information 520 obtained under the control of the CPU 290 is stored in the recording reservation information list 500 as appropriate in a list format. Thereby, when the program information updating means 291 recognizes the change of the EPG, it is possible to immediately determine whether or not the newly generated program information table 400 has the program basic information 420 that matches the reservation information 520. Therefore, the lost program information The presence can be checked immediately.

[0105] The program information analysis means 294 analyzes text format information such as the program title information 434, program subtitle information 435, program genre information 436, and program description information 437 of the program basic information 430, and generates a keyword. Related words are extracted. For this reason, the process of extracting keyword-related words from textual information that stores a plurality of character strings can be easily implemented. Therefore, the program information analysis means 294 can extract keyword-related words with a simple configuration without requiring a complicated analysis program.

[0106] Further, the program information analysis means 294 converts information described in a text format such as the program title information 434, the program subtitle information 435, the program genre information 436, and the program description information 437 of the program basic information 430. , Divided into words and used as keyword-related words. Therefore, by using the keyword-related words of such words, the search efficiency of the lost program information is improved, and the search processing can be easily performed.

[0107] Then, when the program information management means 293 specifies the program basic information 430 as the program basic information 430 that has become lost program information using the keyword-related words, the program information management means 293 has a higher priority order according to a predetermined priority condition. The program basic information 430 is specified in order. Therefore, in particular, when a plurality of pieces of program basic information 430 including keyword-related words are searched, the priority order of these pieces of program basic information 430 is determined, and one piece of program basic information 430 becomes the lost program information. It can be identified as basic information 430. Therefore, since a plurality of pieces of program basic information 430 including keyword-related words are not recorded in the recording reservation information list 500, there is no need for the user to manually delete unnecessary recording reservation information 510. .

[0108] In addition, the priority of the program basic information 430 having the same broadcast time frame as the lost program information is set high. For this reason, for example, the program information management means 293 first compares the lost program information with the program basic information 430 in the same broadcast time as the broadcast time frame of the lost program information. This is because the cause of the lost program information is mainly that the broadcast program itself has not changed, but the program title and program description have been changed. When the basic information 430 includes many keyword-related words, the program basic information 430 can be specified as lost program information. Therefore, by increasing the priority of the program basic information 430 having the same broadcast time frame, the lost program information can be easily obtained. The program basic information 430 that has been reported can be specified.

[0109] Furthermore, even if the basic program information 430 in the same broadcast time frame and the same broadcast start time does not include a keyword-related word, it is not specified as the basic program information 430 that has become lost program information. In this case, the program basic information 430 of the same broadcast time frame is searched, and the program title information 434 includes the keyword-related words described in the recorded program title-related word information 539 of the lost program information. Priority is set high. Then, when the program subtitle information 435 includes the recorded program subtitle related word information 540, it is set as the program priority information 430 having the next highest priority. In this way, by setting the priority according to the type of information including the keyword-related word, for example, when there are a plurality of pieces of program basic information 430 that can be identified as lost program information, the priority is assigned to these pieces of information, and The basic program information 430 with high priority can be specified as the basic program information 430 that has become lost program information. When the program title information 434 is the same as or similar to the recorded program title information 535 of the lost program information, it can be determined that the broadcast programs are the same. Therefore, by increasing the priority when the keyword related words are included in the program title information, the program basic information 430 that has become the lost program information can be specified efficiently.

[0110] Then, the program information management means 293 causes the program information analysis means 294 to analyze the program basic information 430 specified as the lost program information, obtains keyword-related words, and records recorded program title-related word information 539, Recorded in recorded program subtitle related word information 540 and recorded program description related word information 541. Therefore, for example, if the program basic information 430 specified as lost program information becomes lost program information again when a new EPG is acquired and the program information table 400 is updated, these keyword-related words are used. Thus, the program basic information 430 can be easily specified.

[0111] Further, the program information management means 293 records the keyword-related words of the previous lost program information in addition to the keyword-related words analyzed and obtained by the program information analysis means 294. Therefore, for example, when the program basic information 430 becomes lost program information when the program information table 400 is updated, the program basic information 430 that has become lost program information can be identified using these keyword-related words. . Therefore, the program basic information 430 can be specified using many keyword-related words. Basic information 430 can be specified.

[Modification of Embodiment]

The present invention is not limited to the above-described embodiments, but includes the following modifications as long as the object of the present invention can be achieved.

[0113] For example, in the present embodiment, the program information management means 293 causes the program information analysis means 294 to analyze the program basic information 430 specified as the lost program information, to acquire keyword-related words, and Ability to add a keyword-related word of lost program information to a word and record it as a new keyword-related word. For example, only the keyword-related words of the broadcast program that first became the lost program information may be recorded. In this case, if the overwritten program basic information becomes lost program information again, the program basic information that was recorded first and became lost program information can be specified. Therefore, the program basic information most similar to the program content of the broadcast program recorded first can be specified.

In the present embodiment, when specifying the program basic information 430 that has become lost program information, the program information management means 293 determines which information contains the keyword-related word, for example, the program title information 434. The priority order is set according to the power included in the above, but it is not limited to this. For example, the program information management means 293 may set the priority based on the number of keyword-related words included in the program basic information 430. In this case, when the number of keyword-related words included in the program basic information 430 is large, the priority is set high. By setting the priority order in this way, lost program information can be easily specified. Further, such a priority order setting method may be combined with the priority order setting method used in the embodiment. That is, for example, if there is more than one program basic information that includes keyword-related words in the program title information, among these, the one that contains more keyword-related words is determined as lost program information with priority. Well ヽ.

In the present embodiment, the EPG is generated in text format XML or BML, and the program information 410 of the program information table 400 generated based on the EPG is also described in text format. The power of information that is not limited to this. For example, the program information 410 may be compressed data obtained by encrypting and compressing data described in a text format. By using such data, the data capacity of each program basic information can be reduced, The capacity of the group information table 400 can also be reduced. Therefore, the storage space of the storage area such as the HDD can be secured.

Further, in the present embodiment, the program information table 400, the recording reservation information list 500, and the keyword storage area for storing keywords are provided in the HDD 270. The present invention is not limited to this. For example, the configuration may be such that these are stored in a memory. Further, for example, a memory stick or a memory card may be used as the memory, and the memory may be detachable from the recording / reproducing device.

[0117] Further, in the present embodiment, EPG data is received from broadcast waves, but the present invention is not limited to this. For example, a configuration in which an EPG is acquired via a power network such as an HSI may be adopted. Further, a configuration may be adopted in which EPG data is received by a mobile phone, a portable personal computer, or the like, and the received EPG data is transmitted to the recording and reproducing device.

[0118] Further, in the present embodiment, EPG data is received. However, the present invention is not limited to this, and may be other data in which information such as a program guide of a broadcast program or a program introduction is described.

[0119] In addition, specific structures and procedures for implementing the present invention can be appropriately changed to other structures or the like as long as the object of the present invention can be achieved.

[Effects of Embodiment]

When the program information updating means 291 receives an input indicating that the program information table 400 has been updated based on the newly acquired EPG, the program information managing means 293 determines whether or not the lost program information is sufficient. If there is lost program information, the program basic information 430 having the same content as the keyword-related word extracted by the program information analysis means 294 is updated from the updated program information table 400. Information identified as 430. Therefore, even if there is lost program information, the lost program information is not immediately deleted. Therefore, it is possible to prevent a recording error of a broadcast program due to erasure of the lost program information. Conventionally, when the lost program information was deleted, it was necessary to make a recording reservation by inputting the user's manual settings. Since the information 430 is specified and this program information is automatically recorded in the recording reservation information list 500, it is possible to acquire an appropriate broadcast program and make a recording reservation.
