The present invention relates to a data reception terminal and a mail creation method, and more particularly to a data reception terminal that creates, by utilizing information associated with multimedia data (e.g., images, sounds, and the like) which is received via broadcast, communication, or the like, an electronic mail relating to the multimedia data and a mail creation method to be performed in the data reception terminal.
In recent years, TV program broadcast has been experiencing a rapid conversion from analog to digital form. The digital broadcast has been putting various services, which had been difficult for the analog broadcast to provide, to practical use. One example is data broadcasting services. According to a data broadcasting service, a user who is viewing a TV program is capable of easily obtaining information such as weather forecast, a homepage URL of the TV program that is being viewed, and the like, via broadcast. As a description format for data which is used in the data broadcasting service, BML (Broadcast Markup Language) is generally known.
Meanwhile, the sophistication of functionality of mobile phones has been progressing rapidly. Conventionally, a main service provided by mobile phones has been voice communication, but at present, homepage browsing and electronic mail are indispensable. In particular, electronic mail has been replacing voice communication as a main service.
With the situation as described above, in recent years, as mobile phones are beginning to have a digital broadcast receiving function, a compound service combining a digital broadcast receiving function and a mail communication function is proposed. The “compound service” refers to, for example, a service in which, if a user specifies a scene while viewing a TV program, an electronic mail containing attached information relating to the specified scene (scene-related information) is transmitted to a designated destination. Here, a “scene” refers to a part of a TV program, and means broadcast data which is uniquely specified by time, a channel that identifies the program, and/or the like.
An exemplary structure of a conventional mobile phone which realizes such a compound service is shown in
In the conventional technology above, however, although it is possible to automatically attach, as scene-related information, information such as the URL of a homepage of a TV program or the like to an electronic mail, a user has to input and create by operating keys as often as necessary a content the user desires to convey to the other party as the body of the electronic mail. As a result, there occurs a problem in that it takes a long time from when a scene is specified until an electronic mail is transmitted. Consequently, in the case of a TV program in which scenes change from moment to moment, it is conceivable that a scene irrelevant to the content of an electronic mail is being broadcast at the moment that the transmission of the electronic mail is completed. This problem also applies to the case where the multimedia data is music which is broadcast from a radio station.
Therefore, an object of the present invention is to provide a data reception terminal and a mail creation method which, in the case where information related to multimedia data is to be transmitted via electronic mail, makes it possible to perform the creation of an electronic mail easily and accurately, by providing assistance in user input operation when creating the body of the electronic mail.
The present invention is directed to a data reception terminal for receiving multiplexed data obtained by multiplexing multimedia data including at least video or audio and scene-related information related to the multimedia data, and creating an electronic mail by utilizing the multiplexed data. To achieve the object above, a data reception terminal according to the present invention comprises a receiving section, a decoding section, an output section, a storage section, an input/output acceptance section, a retrieval section, a format conversion section, and a mail creation section.
The receiving section receives the multiplexed data. The decoding section separates the received multiplexed data into the multimedia data and the scene-related information. The input/output acceptance section generates, in response to a request from a user, scene specification information for identifying a portion of the multimedia data that is being outputted from the output section, the scene specification information including identification information and time. The retrieval section retrieves, from the storage section, scene-related information corresponding to the scene specification information. The format conversion section converts the retrieved scene-related information into a format which enables the scene-related information to be used in the electronic mail. The mail creation section creates a part of data of the electronic mail by utilizing the converted scene-related information.
Here, preferable methods for creating an electronic mail employed by the mail creation section are, for example: creating a body section of the data of the electronic mail from the scene-related information; setting, as a subject of the electronic mail, a part of the scene-related information corresponding to a title; and displaying, in the electronic mail, data of the electronic mail created from the scene-related information in a form different from that of any other information contained in the electronic mail. It is desirable that data of the electronic mail created from the scene-related information be protected so that a content of the scene-related information is not allowed to be changed.
The processes performed by the afore-mentioned components of the data reception terminal can be regarded as a mail creation method defining a sequence of processing steps. This method is provided in the form of a program for causing a computer to execute the series of processes. This program may be introduced into the computer via a computer-readable recording medium having the program recorded therein. In addition, all or some of the functional blocks that constitute the afore-described data reception terminal may be realized as an LSI, which is an integrated circuit.
As described above, according to the present invention, text data (i.e., scene-related information) for an electronic mail is extracted from information associated with a specified scene. Consequently, it becomes possible to create the electronic mail in a short time and with ease. In particular, the body of an electronic mail can be created by only inputting words to be added between text data. Moreover, the operation of inputting the subject of an electronic mail by a user can be omitted. Furthermore, it is possible to visually distinguish between scene-related information and a part inputted by a user within the body of an electronic mail.
An embodiment of the present invention is described below with reference to the accompanying drawings.
Firstly, there is described an outline of a communication system in which a multimedia digital distribution service and an electronic mail service are combined, and to which a data reception terminal of the present invention is applied.
As shown in
The data reception terminal 102, which is a characteristic feature of the present invention, is a terminal that has both a broadcast function which enables the reception of broadcast data and a communication function which enables the transmission and reception of an electronic mail, and is typically a mobile phone as illustrated in
In the ROM 306, a software program for implementing the system is stored. The CPU 305 executes the program stored in the ROM 306, and performs a writing or updating of occurring data onto the RAM 307. In addition, as a result of executing the program, the CPU 305 receives at the receiving section 301 a broadcast wave which is distributed from the broadcasting station 101, and outputs, via the output section 302, audio and video to the loudspeaker and the display screen 201, respectively. Further, the CPU 305 accepts a key input by the user via the scene specifying button 202 which is connected to the button input section 308. Furthermore, the CPU 305 performs a transmission or reception of an electronic mail via the antenna which is connected to the communication section 304.
In the above, the data reception terminal 102 of the present invention has been described in terms of hardware configuration. Next, a characteristic mail creation method that the data reception terminal 102 of the present invention employs by utilizing at least some of those hardware components is described in terms of software configuration.
The data reception section 401 receives multiplexed data of a TV program which is broadcast from the broadcasting station 101. The decoding section 402 separates the received multiplexed data into video/audio data and accompanying data that contains scene-related information, which is information related to a scene of a TV program. The video/audio output section 403 outputs video and audio. The related information storage section 404 stores and manages the accompanying data. The input/output acceptance section 406 detects a user's specifying of a scene, and generates predetermined scene specification information. The related information retrieval section 405 retrieves corresponding scene-related information based on the scene specification information. The format conversion section 407 converts the retrieved scene-related information into a format which enables the retrieved scene-related information to be put into an electronic mail. The mail creation section 408 creates an electronic mail in which the scene-related information having been subjected to the format conversion is used. The mail communication section 409 transmits the created mail to the general-user terminal 106.

With reference to
Here, with reference to
Therefore, as shown in
With regard to terrestrial digital broadcasting, in the case of digital broadcast for a radio or a mobile terminal such as a mobile phone and the like, broadcast data is divided into thirteen segments, and at least some of the divided segments combined are put to use (
As described above, in terrestrial digital broadcasting, combining of segments enables the utilization of different services, similarly to the services 902 in BS digital broadcast. Therefore, in the case where a plurality of services are included in one channel as a result of the digitization of broadcast, a method for identifying services, such as service channels, may also be incorporated into the scene specification information according to the present invention.
With reference to
Next, the data reception terminal 102 performs the process of converting the format of the retrieved broadcast data so that the retrieved broadcast data can be used as scene-related information (step S604). The scene-related information refers to text data relating to a scene, and includes, for example, a program title, a person appearing in the program, a description of the scene, information unknown to the user, and/or the like. In other words, this format conversion process corresponds to the process of extracting, from the information in the broadcast data, a text which is capable of being used in the body of an electronic mail. To give a specific explanation with reference to
Note that text data extracted as scene-related information by the format conversion does not need to be defined by the tags <title> and </title> or the tags <mailText> and </mailText> as in the above-described example, but may be defined in any other manner. Moreover, there is no limitation as to which scene-related information is to be used in the subject. In the case where there is no scene-related information to be used in the subject, information of an identifier of broadcast data (e.g., the file name of a moving image, audio, a still image, or the like in a relevant scene; a contents ID; or the like) may be used as the subject of a mail. Furthermore, in the case of the above-described example, since it is assumed that broadcast data is written in BML, scene-related information is supposed to be text data. However, scene-related information may be binary data or the like as long as it is data usable for mail creation.
If scene-related information has been put into the body of an electronic mail, the data reception terminal 102 determines whether it is necessary to edit the body of the electronic mail (step S606). The editing here refers to making sentences by adding words such as conjunctions, verbs, and the like to the scene-related information which is merely placed together as shown in
Depending on the broadcasting station 101, it may so happen that making a change to the scene-related information is undesirable to the broadcasting station 101. Such an example is scene-related information which corresponds to a part related to a person's name, a part in which a copyright message is displayed, or the like. It is desirable that such scene-related information be protected against any editing by the user. This protection may be provided at the broadcasting station 101 side by defining a particular tag, or the data reception terminal 102 side may make a judgment and place a restraint as necessary.
Note that the aforementioned technique of distinguishing user-added parts and the aforementioned technique of protecting certain parts of the scene-related information, which have been described in connection with the body of an electronic mail, may also be applied to the subject part of an electronic mail.
Then, the data reception terminal 102 performs a format conversion and a necessary editing (step S607), and transmits the electronic mail, the editing of which has been completed, to a destination user (step S608).
As described above, according to a data reception terminal and a mail creation method according to the embodiment of the present invention, text data (i.e., scene-related information) to be used in an electronic mail is extracted from information associated with a specified scene. Consequently, it becomes possible to create an electronic mail easily and accurately. In particular, the body of an electronic mail can be created by only inputting words to be added between text data. Moreover, the operation of inputting the subject of an electronic mail by a user can be omitted. Furthermore, it is possible to visually distinguish between scene-related information and a part inputted by a user within the body of an electronic mail.
Note that, among the functional blocks of the data reception terminal according to the present invention, the decoding section 402, the related information retrieval section 405, the format conversion section 407, and the mail creation section 408 are typically realized as an LSI, which is an integrated circuit (which is called an IC, a system LSI, a super LSI, an ultra LSI, or the like depending on the degree of integration) (see
Moreover, the method of circuit integration is not limited to LSI, but may be realized by a dedicated circuit or a general-purpose processor. Furthermore, an FPGA (Field Programmable Gate Array), which is an LSI that can be programmed after manufacture, or a reconfigurable processor enabling connections and settings of the circuit cells in the LSI to be reconfigured may be used.
Still further, the advancement of semiconductor technology or another derivative technology may produce a technique for circuit integration that will replace LSI, in which case, as a matter of course, the integration of the functional blocks may be realized by utilizing that technique. A potential example is an application of biotechnology or the like.
In addition, the mail creation method according to the present invention may be realized by a CPU interpreting and executing predetermined program data which is capable of carrying out the above-described process procedure, stored in a storage device (e.g., a ROM, a RAM, a hard disk, or the like). In this case, the program data may be introduced into the storage device via a recording medium such as a CD-ROM, a flexible disk, or the like, or may be executed directly from a recording medium.
A data reception terminal and a mail creation method of the present invention can be employed when information related to multimedia data is transmitted via an electronic mail, for example, and are particularly useful when it is hoped that the creation of an electronic mail be performed in a short time and with ease, for example.
