Description

  The present invention relates to a signal processing device and a signal processing system that output information generated based on subtitles included in a distribution signal.

  Distribution that has been distributed by external devices such as broadcast signals broadcasted by broadcasting stations such as television stations and video signals and audio signals distributed by IP-VOD (Internet Protocol-Video On Demand) service providers. There is known a signal processing device that receives a signal and outputs information generated based on captions included in the received distribution signal.

  As such a signal processing device, for example, in Patent Document 1 below, English subtitles included in a video signal received by a TV tuner are translated into Japanese subtitles, and the Japanese subtitles are displayed on a CRT. A closed caption display device is disclosed.

  In Patent Document 2 below, a term string that is a sequence of independent words extracted from caption information of a program is received from a server, and sign language video information is obtained using sign language action information corresponding to each term included in the received term string. A terminal device that generates and outputs the generated sign language video information is disclosed. Further, in the following Patent Document 2, when the server detects that a subject is missing in a term string, the subject included in the term string extracted before the term string is set as the subject of the term string. Supplementary information is disclosed.

  As disclosed in the above-mentioned Patent Document 2, there are cases in which, for example, syntax elements such as a subject and an object are missing in the subtitles included in the distribution signal. In this case, as disclosed in Patent Document 1, if the caption is translated as it is into a translated caption in another language, a translated caption that does not make sense as the other language may be generated. Therefore, as in the technique disclosed in Patent Document 2, a term that can be a syntactic element missing from a caption included in a distribution signal received in the past is extracted, and the extracted term is supplemented before translation. Can be considered.

  However, in this case, it takes time to analyze past subtitles in order to extract terms that can be syntactic elements missing from past subtitles, and there is a possibility that translation cannot be started quickly. As a result, it becomes impossible to generate translated subtitles so as to keep up with the progress speed of the distribution contents indicated by the distribution signal, and output the translated subtitles in accordance with the progress of the distribution contents as in the technique disclosed in Patent Document 3 above. It may be difficult to do.

  The present invention has been made in view of the above circumstances, and provides a signal processing device and a signal processing system capable of quickly translating subtitles included in a distribution signal into translated subtitles that are meaningful and outputting them. The purpose is to do.

  The signal processing apparatus according to the present invention includes a receiving unit that receives a distribution signal including subtitles in which a distribution content is expressed in a first language, a type of the distribution content, and a case where the distribution content of the type is expressed in the first language. A storage unit that stores in advance a supplementary term that can be supplemented as a predetermined syntax element, and a reception subtitle included in the received signal that is the distribution signal received by the reception unit. And a determination unit that determines whether or not the predetermined syntax element is missing by the determination unit, and associates with the type of delivery content indicated by the received signal in the storage unit A supplementary unit that generates supplemental subtitles by supplementing the received supplemental terms to the received subtitles, a translation unit that translates the supplemental subtitles into translated subtitles in a second language different from the first language, and the received signal Said And an output unit that outputs, including the subtitles, the.

  For example, if the received subtitles are missing syntactic elements such as the subject or object, translating the received subtitles as they are into the translated subtitles in the second language may generate translated subtitles that do not make sense as the second language. There is. Therefore, as in the technique disclosed in Patent Document 2, subtitles included in a distribution signal received in the past are stored, and terms that can be syntactic elements that are missing from the past subtitles stored. It is conceivable that the extracted term is supplemented before translation.

  On the other hand, in the configuration of the present invention, the type of distribution content and supplemental terms that can be supplemented as a predetermined syntax element when the distribution content of the type is expressed in the first language are associated in advance in the storage unit. It is remembered.

  For this reason, when a predetermined syntactic element is missing in the received subtitle, it takes time to analyze the past subtitle to extract a term that can be the predetermined syntactic element from the past subtitle as in the above technique. Even if not, the received subtitle can be quickly supplemented with supplementary terms that are stored in the storage unit in association with the type of distribution content indicated by the received signal and can be the predetermined syntax element suitable for the type of distribution content. Can do.

  As a result, it is possible to quickly translate supplemental subtitles supplemented with predetermined syntax elements suitable for the delivery content indicated by the received signal into translated subtitles that are meaningful as the second language. As a result, a reception signal including the translated subtitle can be output quickly.

  In addition, the storage unit further includes a type of the delivery content, a technical term that can be included when the delivery content of the type is represented in the first language, and an alternative term that can be substituted for the technical term. The supplementary unit further stores the technical term stored in the storage unit in association with the type of delivery content indicated by the received signal, which is included in the supplemental subtitle. It may be replaced with the alternative term associated with the technical term in the section.

  For example, subtitles in which the distribution contents of a strong specialty color such as sports and cooking are expressed in the first language may include technical terms having a meaning different from that used in normal cases. If such subtitles are translated into subtitles in the second language as they are, they are translated into second language terms that have the same meaning as when the above technical terms are normally used, and subtitles that do not make sense as second languages are generated. There is a risk.

  However, according to this configuration, a term having the same meaning as the technical term that can be included when the content of distribution with a strong technical color as described above is expressed in the first language is replaced by the technical term. As described above, it is possible to store the type of distribution content and the technical term in the storage unit in advance.

  As a result, even if the technical terms are included in the supplemental caption, after replacing the technical terms with alternative terms having the same meaning as the technical terms suitable for the type of delivery content indicated by the received signal, Can be translated into translated subtitles. As a result, it is possible to reduce the possibility of generating a translated subtitle that does not make sense as the second language and includes terms that are not suitable for the type of distribution content indicated by the received signal.

  In the storage unit, it is preferable that the technical term representing a proper noun is associated with the alternative term representing the technical term in the second language.

  For example, subtitles representing the content of sports, music, etc. in the first language may contain terms that represent proper nouns such as personal names and stage names, and the terms that represent proper nouns may be common nouns, etc. It may be a term used as another part of speech. If such a subtitle is translated into a second language subtitle as it is, the term representing the proper noun may be translated into a second language term having the same meaning as the other parts of speech.

  However, according to this structure, even if a term used as another part of speech is used as a term representing a proper noun included in the supplemental caption, the term is used as a technical term, The alternative terms that are stored in advance in the storage unit prior to translation of the supplementary subtitles by preliminarily storing the technical terms in the second language in association with the alternative terms expressed in the second language Can be replaced.

  Thereby, it can avoid that the said alternative term already represented by the 2nd language contained in the supplement subtitle is translated by the translation part. As a result, it is possible to reduce the possibility that the term representing the proper noun is translated into a second language term having the same meaning as other parts of speech.

  Further, the received signal may further include program information related to the program being distributed, and the program information may include genre information indicating the type of distribution content.

  According to this configuration, the supplementary unit can acquire program information included in the received signal, and can acquire genre information representing the type of distribution content from the number information indicated by the acquired signal. Thereby, the supplement part can grasp | ascertain quickly the kind of delivery content which the received signal represents with the acquired genre information. As a result, the supplementary unit can quickly acquire supplementary terms and the like stored in the storage unit in association with the grasped distribution content type.

  In addition, the signal processing system according to the present invention includes one or more of the signal processing devices, and the supplementary terms that can be supplemented as predetermined syntax elements when the distribution content type and the distribution content of the type are expressed in the first language. Are stored in association with each other in advance, and each of the signal processing devices includes the type of distribution content stored in the external storage device and the supplementary term associated with the type. An acquisition unit that acquires and stores the acquired information in the storage unit is further provided.

  According to this configuration, the type of distribution content stored in the external storage device and the supplementary terms associated with the type are stored in the storage unit of each signal processing device by the acquisition unit of each signal processing device. The For this reason, the effort which memorize | stores separately the kind of delivery content and the supplementary term matched with the said kind in the memory | storage part of each signal processing apparatus can be omitted.

  In addition, the signal processing system according to the present invention includes one or more of the signal processing devices, and the supplementary terms that can be supplemented as predetermined syntax elements when the distribution content type and the distribution content of the type are expressed in the first language. Are stored in association with each other, and the type of the distribution content, a technical term that can be included when the distribution content of the type is expressed in the first language, and an alternative term that can be substituted for the technical term, Are further stored in association with each other, and each of the signal processing devices acquires the type of the distribution content stored in the external storage device and the supplementary term associated with the type. The storage unit stores the type of distribution content stored in the external storage device and the technical terms and the alternative terms associated with the type and stores them in the storage unit. Further comprising a resulting portion.

  According to this configuration, the type of distribution content stored in the external storage device and the supplementary terms associated with the type are stored in the storage unit of each signal processing device by the acquisition unit of each signal processing device. The In addition, the type of distribution content stored in the external storage device and the technical terms and alternative terms associated with the type are stored in the storage unit of each signal processing device by the acquisition unit of each signal processing device. .

  For this reason, the effort which memorize | stores separately the kind of delivery content and the supplementary term matched with the said kind in the memory | storage part of each signal processing apparatus can be omitted. In addition, it is possible to save the trouble of individually storing the type of distribution contents and the technical terms and alternative terms associated with the types in the storage unit of each signal processing device.

  According to the present invention, it is possible to provide a signal processing apparatus and a signal processing system that can quickly translate a subtitle included in a distribution signal into a translated subtitle that makes sense and output it.

  The storage unit 30 is a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The storage unit 30 previously corresponds to the type of broadcast content indicated by the broadcast signal BS and supplemental terms that can be supplemented as the subject and object (predetermined syntax element) when the type of broadcast content is expressed in Japanese. It is remembered.

  FIG. 2 is a diagram illustrating an example of a table in which types of broadcast contents are associated with supplemental terms. Specifically, the storage unit 30 stores a table associating types of broadcast contents with supplemental terms shown in FIG.

  In the table shown in FIG. 2, for example, the types of broadcast contents represented by the large classification information “sports” and the small classification information “sumo” and supplements that can be supplemented as the subject when the broadcast contents of the type are represented in Japanese. The term “he” is associated with the supplementary term “he” which can be supplemented as an object.

  Further, the storage unit 30 includes types of broadcast contents indicated by the broadcast signal BS, technical terms that can be included when the broadcast contents of the types are expressed in Japanese, and alternative terms that can be substituted for the technical terms. It is stored in advance in association with each other.

  FIG. 3 is a diagram illustrating an example of a table in which broadcast content types, technical terms, and alternative terms are associated with each other. Specifically, the storage unit 30 stores a table associating types of broadcast contents, technical terms, and alternative terms shown in FIG.

  In the table shown in FIG. 3, for example, the type of broadcast content represented by the large classification information “sports” and the small classification information “sumo” and the technical term “ The “place” is associated with the technical term “place” and an alternative term “tournament” that can be substituted.

  In addition, the type of broadcast content represented by the large classification information “sports” and the small classification information “sumo”, and “Kuroiso” representing proper names as technical terms that may be included when the broadcast content of the type is represented in Japanese. Are associated with each other. The technical term “black 鵬” representing the proper noun is associated with “KOKUHOU” representing the technical term “black 鵬” in English (second language) as an alternative term.

  The tables shown in FIGS. 2 and 3 are stored in the storage unit 30 when a control program described later is installed (stored) in a nonvolatile memory described later. Also, the contents of the tables shown in FIGS. 2 and 3 are updated by the acquisition unit 15 described later.

  The operation display unit 40 includes a display unit 41, a speaker 42, and an operation unit 43. The display unit 41 is configured with a liquid crystal display or the like, and displays video and information input from the control unit 10.

  The external storage device 9 is a so-called database server that can communicate with the signal processing device 1 and includes a storage device (not shown) such as an HDD or an SSD. When the external storage device 9 receives a communication signal indicating a transmission request for information stored in the storage device from the signal processing device 1, the external storage device 9 reads the information from the storage device and sends it back to the signal processing device 1.

  In the storage device of the external storage device 9, the type of broadcast content and supplemental terms that can be supplemented as the subject and object when the broadcast content of that type is expressed in Japanese are stored in association with each other. Specifically, a table having the same configuration as the table shown in FIG. 2 (hereinafter referred to as a supplementary table) is stored in advance in the storage device of the external storage device 9.

  In addition, the storage device of the external storage device 9 includes in advance a type of broadcast content, technical terms that can be included when the broadcast content of that type is expressed in Japanese, and alternative terms that can be substituted for the technical terms. It is stored in association. Specifically, a table (hereinafter referred to as a technical term table) having the same configuration as the table shown in FIG. 3 described above is stored in advance in the storage device of the external storage device 9.

  Hereinafter, the operation of the caption translation process will be described. In the description, details of the determination unit 11, the supplement unit 12, the translation unit 13, the output unit 14, and the acquisition unit 15 will be described. FIG. 4 is a flowchart showing the operation of the signal processing system 100.

  As shown in FIG. 4, when the communication unit 20 receives the broadcast signal BS (S1), the determination unit 11 uses the subject and object in the Japanese subtitles included in the broadcast signal BS received by the communication unit 20. It is determined whether or not at least one of them is missing (S2). Hereinafter, the broadcast signal BS received by the communication unit 20 is referred to as a received signal, and the Japanese subtitles included in the received signal are referred to as received subtitles.

  When the determination unit 11 determines that at least one of the subject and the object is missing in the received caption (S2; YES), the supplement unit 12 stores the table shown in FIG. In step S3, supplementary captions are generated by supplementing the received captions with supplemental terms associated with the type of broadcast content indicated by the received signal (S3). On the other hand, when the determination unit 11 determines that neither the subject nor the object is missing in the received subtitle (S2; NO), the supplementary unit 12 generates the received subtitle as it is as a supplemental subtitle (S4).

  Hereinafter, steps S2 to S4 will be described in detail using specific examples. In the following, as a specific example, it is assumed that the program information included in the received signal includes genre information including large classification information “sports” and small classification information “sumo”. In addition, it is assumed that the received subtitle is “Closed. The training in front of the place was enough”.

  In step S <b> 2, the determination unit 11 first analyzes the received caption by a known morphological analysis method and syntax analysis method. As a result of the analysis, the determination unit 11 confirms that the received subtitles include two sentences, the first sentence “Cut it up close” and the second sentence “The training before the place was enough”. To grasp.

  Thus, the received subtitles are not limited to one sentence, and may include a plurality of sentences. For this reason, in step S2, the determination unit 11 determines whether or not at least one of the subject and the object is missing in each sentence included in the received caption. In accordance with this, the supplementary unit 12 generates supplementary sentences corresponding to the respective sentences in step S3 or S4 based on the determination results for the respective sentences by the determination unit 11, and then combines them to generate supplemental subtitles. Generate.

  Specifically, as a result of the above analysis, the determination unit 11 does not include either the subject or the object in the first sentence “closed”, and includes the transitive verb “closed” as a predicate. To understand that In this case, the determination unit 11 determines that the subject is missing in the first sentence because the subject is not included in the first sentence. In addition, since the first sentence does not include the object in the first sentence, the determination unit 11 determines that the first sentence does not include the target verb in the first sentence. It is determined that the object is missing. That is, the determination unit 11 determines that the subject and the object are missing in the first sentence (S2; YES).

  In this case (S2; YES), in step S3, the supplementary unit 12 acquires program information included in the received signal, and acquires genre information included in the acquired program information. Thereby, the supplement part 12 is that the kind of broadcast content which a received signal shows is the kind of broadcast content represented by the large classification information "sports" and the small classification information "sumo" contained in the acquired genre information. To figure out.

  Then, in the table shown in FIG. 2, the supplement part 12 is associated with the type of broadcast content represented by the large classification information “sports” and the small classification information “sumo”, and can be supplemented as a subject “supplement term”. Acquires the supplementary term “he” that can be supplemented as “he” and the object. The supplementary unit 12 supplements the supplementary term “he” that can be supplemented as the acquired subject and the supplementary term “he” that can be supplemented as the object as the subject and object of the first sentence, respectively. Generates "He has crossed him."

  On the other hand, as a result of the above analysis, the determination unit 11 includes the noun “practice” as the subject and the adjective verb “sufficient” as the predicate in the second sentence “the practice before the place was sufficient”. Know what is included. In this case, since the second sentence includes the subject, the determination unit 11 determines that the subject is not missing in the second sentence. Further, the determination unit 11 does not include the object in the second sentence, but includes an adjective verb that does not require the object as a predicate. judge. That is, the determination unit 11 determines that neither the subject nor the object is missing in the second sentence (S2; NO).

  In this case (S2; NO), the supplement part 12 produces | generates the 2nd sentence "The training before the place was enough." As a 2nd supplement sentence in step S4 as it is.

  And the supplement part 12 combined the 1st supplement sentence produced | generated by step S3, and the 2nd supplement sentence produced | generated by step S4, and correction subtitle "He crossed him. The practice before the place was enough. Is generated.

  Returning to FIG. Next, the supplementary unit 12 determines whether or not the technical term stored in the storage unit 30 in association with the type of broadcast content indicated by the received signal is included in the supplemental subtitle (S5).

  When it is determined in step S5 that the technical term is included in the supplemental caption (S5; YES), the supplementing unit 12 replaces it with an alternative term associated with the technical term in the storage unit 30 (S6). On the other hand, if it is determined in step S5 that the technical term is not included in the supplemental caption (S5; NO), the supplement unit 12 does not execute step S6.

  Hereinafter, Steps S5 and S6 will be described in detail using the above-described specific example. In other words, it is assumed that the supplementary subtitle is "He has crossed him. The practice in front of the place was enough." Further, it is assumed that program information included in the received signal includes genre information including large classification information “sports” and small classification information “sumo”.

  In step S5, the supplementary unit 12 first acquires program information included in the received signal, and acquires genre information included in the acquired program information. Thereby, the supplement part 12 is that the kind of broadcast content which a received signal shows is the kind of broadcast content represented by the large classification information "sports" and the small classification information "sumo" contained in the acquired genre information. To figure out. In addition, the supplement part 12 does not need to acquire genre information in step S5, when genre information has already been acquired in step S3.

  Then, the supplement unit 12 extracts the independent words “he”, “close-by”, “in front of place”, “practice”, and “sufficient” included in the supplement subtitles by a known morphological analysis method. And the supplement part 12 is a kind of the broadcast content represented by the large classification information “sports” and the small classification information “sumo” in the table shown in FIG. 3 stored in the storage unit 30 among the extracted independent words. It is determined whether there is an independent word that matches the technical term associated with.

  As a result of the determination, if it is determined that there is an independent word that matches the technical term, the supplementing unit 12 determines that the technical term is included in the supplemental caption (S5; YES), and the independent word that matches the technical term. Is determined not to exist, it is determined that the technical term is not included in the supplemental caption (S5; NO).

  In this specific example, the supplementary unit 12 determines the type of broadcast content in which the independent word “in front of place” extracted from the supplementary subtitles is represented by the large classification information “sports” and the small classification information “sumo” in the table shown in FIG. Therefore, it is determined that the technical term is included in the supplemental caption (S5; YES).

  In this case (S5; YES), in step S6, the supplement unit 12 associates the technical term “before location” included in the supplemental caption with the technical term “before location” in the table shown in FIG. Replace with the alternative term "before tournament". As a result, the corrected subtitle becomes "He has crossed him. The training before the tournament was enough."

  Returning to FIG. Next, the translation unit 13 translates the supplemental subtitles into English translation subtitles based on a predetermined translation logic by a known translation program (S7).

  For example, as shown in the above-mentioned specific example, it is assumed that the supplementary subtitle is “He has crossed him. The training before the tournament was enough”. In this case, in step S7, the translation unit 13 changes the supplemental subtitle “He has cut him off. The training before the tournament was sufficient” to the translated subtitle “He forced him out. Lessons before tourenen enough. Translate to

  As another specific example, for example, it is assumed that the corrected subtitle immediately before executing step S5 is “the master congratulates the black panther”. In this case, in step S5, the supplement unit 12 determines that the technical terms “master” and “black panther” are included in the supplement subtitle (S5; YES). In this case, in step S6, the supplementary unit 12 corresponds to the technical terms “master” and “black panther” included in the supplemental subtitles to the technical terms “parent” and “black panther” in the table shown in FIG. Replaced with the alternative terms “OYAKATA” and “KOKUHOU”. As a result, the corrected caption is “OYAKATA congratulates KOKUHOU”.

  In this case, the translation unit 13 translates the corrected subtitle “OYAKATA congratulates KOKUHOU” into the translated subtitle “OYAKATA presses KOKUHOU.” In step S7.

  Returning to FIG. Next, the output unit 14 includes the translated caption generated in step S7 in the received signal and outputs the received signal (S8).

  Specifically, in step S8, the output unit 14 includes the translated subtitle in the received signal and outputs the received signal to the operation display unit 40. Thereby, the display unit 41, when the received signal includes a video signal, the video indicated by the received video signal, the received subtitle included in the received signal, and the translation included in the received signal. Of the subtitles, the video and / or subtitles selected by the user operating the operation unit 43 are displayed. Similarly, when the received signal includes an audio signal indicating one or more sounds, the speaker 42 selects the sound selected by the user operating the operation unit 43 from the one or more sounds. Output.

  In addition to the operation shown in FIG. 4, the acquisition unit 15 acquires the type of broadcast content stored in the external storage device 9 and supplemental terms associated with the type and stores them in the storage unit 30. To do. In addition, the acquisition unit 15 acquires the type of broadcast content and the technical terms and alternative terms associated with the type stored in the external storage device 9 and stores them in the storage unit 30.

  Specifically, the acquisition unit 15 is stored in the external storage device 9 at a predetermined timing such as when the signal processing device 1 is initially activated or when step S1 is first executed after the initial activation. A communication signal indicating a transmission request for the supplementary table and the technical term table is transmitted to the external storage device 9 by the communication unit 20.

  When the external storage device 9 receives the communication signal, the external storage device 9 reads the supplementary table and the technical term table from the storage device and returns them to the signal processing device 1. When the communication unit 20 receives the supplementary table and the technical term table returned from the external storage device 9, the communication unit 20 outputs the received supplemental table and technical term table to the control unit 10.

  When the supplementary table is input from the communication unit 20, the acquisition unit 15 updates the contents of the table shown in FIG. 2 stored in the storage unit 30 with the contents of the supplementary table. Further, when the technical term table is input from the communication unit 20, the acquisition unit 15 updates the contents of the table shown in FIG. 3 stored in the storage unit 30 with the contents of the technical term table.

Hereinafter, the effect produced by the configuration of the embodiment will be described.
(1) If at least one syntax element of the subject and object is missing in the received subtitles, translating the received subtitles as they are into English translated subtitles will generate translated subtitles that do not make sense as English There is a risk. Therefore, as in the prior art, subtitles included in broadcast signals received in the past are stored, and a term that can be the at least one syntax element missing from the stored past subtitles is used. It is possible to extract and supplement the extracted terms before translation.

  On the other hand, in the configuration of the above embodiment, the type of broadcast content and the supplemental term that can be supplemented as the subject and the supplemental term that can be supplemented as the object when the broadcast content of the type is expressed in Japanese are: The information is stored in the storage unit 30 in advance.

  For this reason, when at least one syntax element of the subject and the object is missing in the received subtitle, in order to extract a term that can be the at least one syntactic element from the past subtitles as in the conventional technique The above-described at least one syntax element suitable for the type of broadcast content stored in the storage unit 30 in association with the type of broadcast content indicated by the received signal without taking time to analyze past subtitles. The received supplemental terms can be quickly supplemented to the received subtitles.

  As a result, it is possible to quickly translate the supplemental subtitle supplemented with the at least one syntax element suitable for the broadcast content indicated by the received signal into a translated subtitle that makes sense as English. As a result, a reception signal including the translated subtitle can be output quickly.

  (2) For example, subtitles that express broadcast contents of strong specialized colors such as sports and cooking in Japanese may include technical terms that have different meanings from those that are normally used. If such subtitles are translated into English subtitles as they are, the above technical terms may be translated into English terms having the same meaning as in the normal use, and subtitles that do not make sense as English may be generated.

  However, according to the configuration of the above embodiment, a term having the same meaning as a technical term that can be included in the case where the broadcast content of a type having a strong technical color as described above is expressed in Japanese can be substituted for the technical term. As an alternative term, it can be stored in the storage unit 30 in advance in association with the type of the broadcast content and the technical term.

  As a result, even if the technical terms are included in the supplemental caption, after replacing the technical terms with alternative terms having the same meaning as the technical terms suitable for the type of broadcast content indicated by the received signal, Can be translated into translated subtitles. As a result, it is possible to reduce the possibility of generating translated subtitles that do not make sense as English, including terms that are not appropriate for the type of broadcast content indicated by the received signal.

  (3) For example, subtitles expressing sports content such as sports and music in Japanese may include terms representing proper nouns such as personal names and stage names, and the terms representing proper nouns are common nouns. The term may also be used as another part of speech. If such subtitles are translated into English subtitles as they are, there is a risk that the term representing the proper noun will be translated into an English term having the same meaning as the other parts of speech.

  However, according to the configuration of the above embodiment, even if a term used as another part of speech is used as a term representing a proper noun included in the supplemental caption, the term is used as a technical term, The term is stored in advance in the storage unit 30 before translation of the supplementary subtitles by storing the term and the alternative term representing the technical term in English in association with each other in the storage unit 30. It can be replaced with the above alternative terms.

  Thereby, it is possible to avoid the translation unit 13 from translating the alternative terms already included in the supplemental subtitles and expressed in English. As a result, it is possible to reduce the possibility that the term representing the proper noun is translated into an English term having the same meaning as other parts of speech.

  (4) In the configuration of the above embodiment, the received signal further includes program information related to the program being broadcast, and the program information includes genre information indicating the type of broadcast content.

  For this reason, the supplement part 12 can acquire the program information contained in the received signal, and can acquire the genre information representing the type of broadcast content from the number information indicated by the acquired signal. Thereby, the supplement part 12 can grasp | ascertain rapidly the kind of broadcast content which the received signal which the acquired genre information represents shows. As a result, the supplement unit 12 can quickly acquire supplement terms and the like stored in the storage unit 30 in association with the grasped broadcast content type.
