-Recording process etc. Next, operation | movement of the broadcast recording apparatus 10 which has such a structure is demonstrated in detail. First, the operation during recording will be described in detail, including other embodiments. As an input side of the broadcast recording apparatus 10, a communication unit 11 such as a LAN is connected to an external device and communicates with a program information providing server S or the like via a communication path such as the Internet via a modem M or the like. , Download content information, etc. The BS / CS tuner unit 12 and the terrestrial tuner unit 13 select a broadcast signal via an antenna, demodulate it, and input a video signal and an audio signal, and support a wide variety of broadcast signals. For example, it covers terrestrial analog broadcasting, terrestrial digital broadcasting, BS analog broadcasting, BS digital broadcasting, CS digital broadcasting, and the like, but is not limited thereto. Also, it is not always necessary to provide only one. For example, it has two or more tuners for terrestrial analog broadcasting and two or more BS / CS tuners, and functions in parallel in accordance with the reservation recording request. This includes cases where

  The communication unit 11 may be an IEEE 1394 interface, and can receive digital content from an external device on the network. It is also possible to receive a luminance signal, a color difference signal, a video signal such as a composite, and an audio signal from an input end (not shown). These inputs are controlled by the selector 16 controlled by the control unit 30 and the like, and are selectively supplied to the encoder unit 21.

  The encoder unit 21 includes a video and audio analog-to-digital converter that digitizes an analog video signal and an analog audio signal input by the selector 16, a video encoder, and an audio encoder. Furthermore, a sub-picture encoder is also included. The output of the encoder unit 21 is converted into a predetermined compression format such as MPEG and supplied to the previous control unit 30.

<An example of a playback title recommendation function of a broadcast recording apparatus according to an embodiment of the present invention>
Next, a reproduction title recommendation function using the preference detection result of the broadcast recording apparatus 10 will be described in detail below with reference to a flowchart.

  Here, FIG. 2 is an explanatory diagram showing an example of the data structure of the title of the preference database in the broadcast recording apparatus according to an embodiment of the present invention. FIG. 3 is an explanatory diagram showing an example of the data structure of a genre database in the broadcast recording apparatus according to an embodiment of the present invention. FIG. 4 is an explanatory diagram showing an example of the data structure of the channel of the preference database in the broadcast recording apparatus according to the embodiment of the present invention. FIG. 5 is an explanatory diagram showing an example of the data structure of the title database in the broadcast recording apparatus according to the embodiment of the present invention. FIG. 6 is a flowchart illustrating an example of a recommendation level calculation method for each title according to user preference in the broadcast recording apparatus according to the embodiment of the present invention.

(Operation)
First, the recording tendency of the title selected at the time of reserved recording and the preference database are generated by the functions of the reserved recording unit, preference detecting unit, and recommendation unit 42 of FIG.

  Specifically, the recording tendency of the title selected at the time of scheduled recording and the reproduction tendency of the title selected to be reproduced by the user by the functions of the reservation recording unit / preference detection unit / recommendation unit 42 are shown in FIG. Thus, for example, 3 points are given to the word, “music”, etc. used in the recording reservation. Similarly, as shown in FIG. 3, for example, 20 points are given to a word for identifying a genre used at the time of recording reservation (or playback process), “Japanese music”, and the like. Similarly, as shown in FIG. 4, for example, 10 points are given to the channel, “MHK”, etc., selected at the time of recording reservation (or at the time of playback processing). That is, what is desired by the user by adding points as the operation information of the user for the word and genre from the title name and the detailed contents of the title and the channel selected by the tuner units 12 and 13. Is created to create a preference database. In addition, although reservation recording was demonstrated to the example, not only reservation recording but the title at the time of recording the program which is airing now by remote control operation etc. is also made into a database as a sample of preference.

  That is, the degree of recommendation of each title is calculated by determining the plurality of titles for which program information has been acquired based on the above-described preference database by the functions of the reserved recording unit, the preference detection unit, and the recommendation unit 42. For example, as shown in FIG. 5, one title has information such as title ID, title name, detailed contents, genre, channel, program time, and the like.

  Here, an example of a method for calculating the recommendation level of each title will be described with reference to FIG. In FIG. 6, the recommendation point is initialized to “0” in the operation of the preference detection unit / recommendation unit 42 (step S11).

  Calculate recommended points of channel information given by scheduled recording. That is, channel preference points are acquired from the database and added as recommended points (step S12). Also, the recommended point of the title information given by the reserved recording or the like is calculated. That is, genre preference points are acquired from the genre database and added as recommended points (step S13). Further, only one word is extracted from the title name (step S14), and it is determined whether there is a word registration in the preference database (step S15). If it exists, the number of points is acquired from the preference database as 3 points, for example (step S16), and the word points are added as recommended points (step S17). This process is repeated until the end of the title name is reached (step S18). Also, the program contents are also added in the same way as the title name, and the recommended points of the title are set as No. 1 in FIG. As shown in FIG. 10, for example, 100 points are calculated (step S19).

  If the program is a new program, the points added up to now are doubled (step S20). This new program addition process will be described with reference to FIG.

  First, the character string information of the program name is stored (step S31). Then, it is determined whether or not “[new]” is included in the character string information of the program name (step S32), and if it is included, it is determined that the program is a new program (step S34).

  In step S32, even if “[new]” is not included in the character string information of the program name, the number of stories is included in the program name, and the numbers constituting the number of stories are one, first, and first. If it is a character representing the first time, it is determined that the program is a new program, and the process proceeds to step S34 (step S33).

  If it is determined that the program is a new program, the calculated points are doubled (step S35). Note that the point addition method in the case of a new program is not limited to double, and other magnifications may be used. For example, a certain numerical value such as 100 points may be added.

  If nothing is included in steps S42 and S43, it is determined that the program is not a new program.

  As described above, the new program determination process and the addition process can be performed by the process described above. As a result, the user can easily notice the new program.

  If it is not judged as a new program, points are added according to the number of stories (W) / total number of stories (M). In addition, what is added by the number of stories / total number of stories is not limited to plus points, and there may be minus points.

  Next, point increase / decrease calculation processing according to the number of stories / total number of stories will be described with reference to FIG.

  First, program name character string information is stored (step S41). Then, information on the number of stories is extracted from the character string information of the program name (step S42). The information on the number of stories is, for example, in the form of “No. ○ Story”, “No. ○”, “# ○”, and (○) (“◯” is a number indicating the number of stories). Then, it is determined whether or not the information on the total number of stories is included in the character string information of the program name (step S43). The information on the total number of stories is, for example, in the form of “all x stories” (× is a number indicating the number of stories). If information on the total number of stories is included, the value of the total number of stories is extracted (step S44).

  When the total number of stories is extracted, the number of stories (W) / total number of stories (M) and points corresponding to the graph shown in FIG. 9 are added (step S45). If it is determined that the total number of stories is not included, the number of stories (W) and points corresponding to the graph shown in FIG. 10 are added (step S46).

  FIG. 9 shows the addition points when the total number of stories (M) is known. For example, as the number of stories (W) becomes the second half, the continuity of the series program tends to make the user feel unavoidable even after seeing the second half of the series. Therefore, when the total number of stories is known, points are added according to the graph shown in FIG. In FIG. 9, the horizontal axis indicates the number of stories in total, with the beginning toward the left and the end toward the right. The vertical axis is the evaluation value, and the higher the recommendation level, the lower the recommendation level.

  In addition, from the first half to the middle of the series, it is easy to lack excitement in the “start” and “approval” of the start-and-end rolling. Also, from the middle to the second half of the series, the “rolling” and “ending” of the incoming and outgoing rolls tend to rise gradually. Therefore, instead of the graph shown in FIG. 9, points according to the number of stories may be added according to the graph shown in FIG. In FIG. 11, the horizontal axis indicates the number of stories as a whole, with the beginning toward the left and the end toward the right. The vertical axis represents the evaluation value, the higher the recommendation level, the lower the recommendation level.

  On the contrary, by taking the fact that there is no meaning unless all the series programs are prepared, by recording and watching the last half of the excitement and the last episode with a high audience rating, if you are interested, you can encourage pay broadcasting, etc. It is also possible to encourage the viewing of popular dramas and recommend products and contracts to complement the broadcast times that have already been broadcast.

  Next, a graph (FIG. 10) in which the total number of stories is not known will be described. For example, even if you don't know the total number of episodes, a long-lived program with a large number of episodes will surely be an interesting program. Therefore, points are added according to the graph shown in FIG. In FIG. 10, the recommendation degree gradually decreases until 50 times. And when it exceeds 50 times, a recommendation degree goes up to multiplication. For example, when the number of recommendations exceeds 100, the recommendation level is constant at the highest level.

  The reserved recording unit / preference detection unit / recommendation unit 42 automatically schedules and records programs whose calculated points are a predetermined value or more. Further, the reserved recording unit / preference detection unit / recommendation unit 42 displays a list of programs whose points are equal to or greater than a certain value in accordance with a user operation.

With the various embodiments described above, those skilled in the art can realize the present invention. However, it is easy for those skilled in the art to come up with various modifications of these embodiments, and have the inventive ability. It is possible to apply to various embodiments at least.
