2. Description of the Related Art Conventionally, moving pictures, still pictures,
Information such as voices, characters, and programs are exchanged. However, in either case of the Internet or personal computer communication, the information receiver side accesses the information source and selects and downloads (downloads) necessary information from the storage device of the source. Therefore, the receiver cannot obtain the information without taking any action on the source of the information. That is, unlike a general television broadcast, information cannot be obtained by a simple operation such as simply selecting a channel. As described above, an information communication system that requires an operation on the receiver side cannot be used as information communication means for publicity and publicity.

[0003] In response to such a problem of multimedia information communication, in recent years, a large number of recipients who want to receive information are accessed from a source of the information via a public line, and the information on the recipient side (each household) is transmitted. Regardless of the necessity or non-necessity, the information is sent to the receiver side and stored in the receiver side, and the receiver side selects the display operation of the data storage device (that is, the data receiving device), for example, by selecting the display operation. An information communication system that displays information on a screen by the same operation as the selection of a broadcast channel has been considered.

Further, with the development of digital technology, a digital broadcasting system in which various kinds of information including a broadcasting signal are digitized has been researched and developed in the broadcasting field. In such a system, an integrated digital system (ISDB)
(Referred to as an Integrated Services Digital Broadcasting) system). In the ISDB system, multimedia information is digitized and integrated and multiplexed for transmission. When integrating and multiplexing various types of information, additional information used as control information on the receiving side must be transmitted in addition to this information. Can be.

[0005] Therefore, if the above system is used, a service for transmitting various information such as news, sports, weather forecast, leisure information, and program-related information can be realized.

In such a case, there is a problem that the user cannot efficiently search for desired information when browsing the information with the receiving device. In addition, the information provider adds a keyword to transmission information or transmits a transmission schedule in advance in response to a request for a user to continuously browse. Japanese Patent Laid-Open No. 8-263410 proposes a method in which a keyword for information desired on the receiving side is designated, and information is selected by collating the keyword with the keyword added to the received information. However, there has been a problem that the receiving side alone does not browse information other than the designated information as the receiving side, so that the chance of finding new information decreases, and the transmitting side cannot expect to increase the number of new users.

On the other hand, in recent years, an increase in the power consumption of the receiving terminal has become a problem, and there has been an increasing demand for reducing the power consumption of the receiving device while unnecessary information is being transmitted to the user. Then, there was a problem that an increase in power consumption could not be suppressed.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) Here, as one embodiment of the present invention, an information transmitting apparatus using satellite digital broadcasting is shown.

FIG. 1 is a system configuration diagram according to the first embodiment of the present invention.

In FIG. 1, reference numeral 101 denotes an information receiving unit for receiving content information such as video, audio, text, and data; 102, an additional information receiving unit for receiving a notice keyword; 103, content received by the information receiving unit 101; A received information combining unit 104 combines the information and the notice keyword received by the additional information receiving unit 102, and a display unit 104 displays the information combined by the received information combining unit 103.

In FIG. 1, each of the information receiving section 101 and the additional information receiving section 102 is a means for receiving a satellite broadcast. Therefore, in the case of the present embodiment, it is assumed that the content information and the preview keyword information are respectively broadcast on different broadcast channels. Aside from this,
Of course, a configuration in which one information is transmitted by satellite broadcasting and the other information is transmitted by a public telephone line may be used.

Each of the above components corresponds to the information receiving unit 101 corresponding to the first receiving unit of the present invention, and the additional information receiving unit 102 corresponding to the second receiving unit. Further, the reception information processing / display means of the present invention comprises:
This is a unit including the display unit 104. Further, the preview keyword is an example of the preview information of the present invention, but is not limited to a keyword having a narrow meaning consisting of a character string. For example, a number other than a character, an illustration or a graphic, or a character, a numeral, It also includes information based on graphics, voice, or a combination thereof.

FIG. 28 shows the hardware configuration of this embodiment.
Shown in FIG. 28 is basically the same as the configuration of the general-purpose computer system, except that a receiving means for receiving the satellite digital broadcast is added.

The operation of the information receiving apparatus configured as described above will be described with reference to the flowchart of FIG.

In step 201, the received data is decoded. The satellite wave received from the receiving antenna is assembled from the stream into packets, and further reconstructed from a plurality of packets into data constituent units (eg, files, programs, etc.). After decryption, the data-added identifier is determined, and the process proceeds to step 202 in the case of the notice keyword, and to step 203 in the case of the content information. Note that the above determination on the identifier is made by the information receiving unit 10.
1 and the additional information receiving unit 102. This is because various data may be multiplexed in any channel, and it is necessary to determine the identifier after assembling the packet. The multiplexed data may be, for example, a notification from a broadcasting station or data of another service such as karaoke.

In step 202, the reception information synthesizing section 10
By 3, processing for displaying the notice keyword on the display unit simultaneously with the received information is performed. In the present embodiment, the received information is HTML (Hyper Text Markup Laptop).
nguage) and shall be browsed by a dedicated browser. It is assumed that the received notice keyword is shown in FIG. In this case, FIG.
Create the HTML file shown in (a), and
A file serving as a base for a new composition shown in FIG.

In step 203, the reception information synthesizing section 10
According to 3, a process for displaying the content information on the display unit simultaneously with the notice keyword is performed. The file name is changed as shown in FIG. 4B in order to combine with the base file prepared in step 202.

In step 204, the display unit 10
4, the content information and the notice keyword are displayed. The browsing of information uses an HTML browser. In steps 202 and 203, H
Since the content information and the notice keyword are combined so as to be displayed at the same time by using the TML frame tag, by displaying the base file shown in FIG. At the same time, you can browse the notice keywords. FIG. 5 shows a display example.

As described above, the user can confirm the contents of the information to be transmitted next time when viewing the received information.

In the first embodiment, satellite digital broadcasting is used as the communication means.
An ATV line or terrestrial broadcasting may be used. Further, different communication units may be used in the information receiving unit and the additional information receiving unit. Further, the information receiving unit and the additional information receiving unit may be realized as one unit without being separated.

Although the content information and the notice keyword information are combined and displayed, they may be simply displayed side by side on the display without being combined.

In the present embodiment, it is necessary that relevancy information indicating the relevance between the first content information and the notice information be sent from a broadcasting station. For example, when a plurality of types of content information are broadcast on a plurality of channels, the preview information of the content related to the content of each content information is broadcast on which channel without this relevance information. This is because the receiving device does not know. The same can be said for the embodiments described below. Further, the relevancy information may be sent separately, or may be sent after being added to either the content information or the notice information.

(Embodiment 2) Here, as one embodiment of the present invention, an information receiving apparatus using satellite digital broadcasting is shown.

FIG. 6 is a system configuration diagram according to the present embodiment. FIG. 6 includes the same parts as those of the system configuration of the first embodiment of the invention shown in FIG. 1, and therefore, the same parts are denoted by the same reference numerals and description thereof will be omitted. Only different parts will be described.

An information separating unit that separates a notice keyword in the content information received at 601 from the received information.

The above components correspond to the information receiving unit 601 and the information separating unit 602, respectively.

The operation of the information receiving apparatus configured as described above will be described with reference to the flowchart of FIG.

At step 701, the received data is decoded. The satellite wave received from the receiving antenna is assembled from the stream into packets, and further reconstructed from a plurality of packets into data constituent units (eg, files, programs, etc.). The reconstructed data does not always include the notice keyword. For example, when information is composed of text, images, and audio, adding a notice keyword to each component wastes communication capacity. Therefore, a notice keyword is added to a representative component. Whether or not the notice keyword has been added is determined by the identifier. If the notice keyword has been added, the process proceeds to step 702, and if not, the process proceeds to step 705.

At step 702, the notice keyword in the content information is separated from the received information. In the information including the notice keyword, the notice keyword size and the keyword are continuously added to a predetermined area.
For example, when it is determined that the notice keyword is added to the head of the received information, the designated size is read from the start to know the size of the notice keyword. Then, the notice keyword is separated from the read place by reading data of the size of the notice keyword read.

(Embodiment 8) Next, as an embodiment of the present invention, an information receiving apparatus using digital satellite broadcasting will be described.

FIG. 24 is a system configuration diagram according to the eighth embodiment of the present invention. FIG. 24 includes the same parts as those of the system configuration according to the fifth embodiment of the invention shown in FIG. 16, and therefore, the same parts are denoted by the same reference numerals and description thereof will be omitted. Only different parts will be described.

In the figure, 2401 is a clock for acquiring the current time, 2402 is a power supply control unit for controlling the power supply of the receiving unit. The power supply control unit 2402 compares the next scheduled transmission date and time stored in the reserved keyword database 1602 with the current date and time acquired from the clock 2401, and when the two match, the information receiving unit 1
01 is a unit for supplying power. 2403
Is a reception period receiving unit that receives information on a period during which content information transmitted from the transmission station is received on the reception side (hereinafter, this is referred to as a reception period). The information on the reception period sent from the transmitting station may include information for specifying a broadcast channel of the content information (for example, a broadcast program).

The clock 2401 is used as the current time acquisition unit of the present invention, the power supply control unit 2402 is used as the power supply control unit, and the reception period receiving unit 2403 is used as the reception period reception unit. Applicable.

The operation of the information receiving apparatus configured as described above will be described with reference to the flowchart of FIG.

In step 2501, the information receiving unit 101
To determine if power is to be supplied. As shown in FIG. 31, the additional information database 901 stores the next scheduled transmission date and time and reception period for each notice keyword. The power supply control unit 2402 compares the date and time with the current date and time acquired from the clock 2401. If the two match, the process proceeds to step 2502. Otherwise, step 2501 is repeated.

Note that, depending on the form of the communication channel, the transmission time (the difference between the transmission time and the reception time, ie, the time required for transmission) cannot be ignored. In such a case, the transmission time is reduced. What is added to the above-described next scheduled transmission date and time may be transmitted as the next scheduled transmission date and time. By doing so, there is no need to provide a means for correcting the error on the receiving device side, and the configuration on the receiving device side can be simplified. Alternatively, a means for correcting the error may be provided in the receiving device in advance. As described above, in the case of the configuration in which the correction unit is provided on the receiving device side, the above-described transmission time is not added to the next scheduled transmission date and time transmitted from the transmitting device side.

In step 2502, the power supply control unit 2

The power supply control unit 2402 compares the reception period received by the reception period receiving unit 2403 with the reception period sent to the additional information database 901 and recorded. If the reception time is shorter than the reception period, step 2503 is repeated. Otherwise, step 2
The processing shifts to 504, where power supply to the information receiving unit 101 is terminated. Note that the reception period may not be predictable in advance depending on the form of the communication path, such as a general public line. In such a case, a period calculated on the assumption that transmission is performed at the slowest communication speed may be transmitted as the reception period. In this case, an identifier indicating the completion of the transmission of the content information is added to the end of the content information. Then, the receiving device immediately stops power supply to the power information receiving unit 101 after receiving the identifier.

In addition, separately from this, when the error between the transmission period and the reception period can be predicted in advance, and when the transmission period of the content information to be transmitted is transmitted from the transmission side, May be provided with the following prediction means in the receiving apparatus. That is, the predicting means is means for processing a period in which the transmission period previously received by the receiving device and having been corrected in accordance with the state of the communication path as the above-described reception period. In addition, it is of course also possible to adopt a configuration in which the above error is considered in advance on the transmitting side and then transmitted.

At step 2504, the received data is decoded. The satellite wave received from the receiving antenna is assembled from the stream into packets, and further reconstructed from a plurality of packets into data constituent units (eg, files, programs, etc.). After decryption, the identifier to which the data has been added is determined, and the process proceeds to step 2505 if the identifier is additional information, or to step 2506 if the information is information.

At step 2505, the received additional information is stored in the additional information database. The additional information includes a classification item, a content keyword, a notice keyword, a next scheduled transmission date and time, and a reception period, and its format is determined in advance. The additional information extracted according to the format is added to the additional information database 901. When a notice keyword for a previously received classification item is newly received, the notice keyword is overwritten.

In step 2506, the information receiving unit 101
Is stored in the reservation information database 1604.

Steps 2507 through 2511 are

FIG. 26 is a system configuration diagram according to the ninth embodiment of the present invention. FIG. 26 includes the same parts as those of the system configuration of the fifth embodiment of the invention shown in FIG. 16, and therefore, the same parts are denoted by the same reference numerals and the description thereof will be omitted, and only different parts will be described.

Referring to FIG. 26, reference numeral 2601 denotes a clock for acquiring the current time; 2602, a power supply control unit for controlling power supply to the receiving unit and the additional information receiving means; and 2603, a receiving period receiving unit.

[0165] The components described above are such that the clock 2601 is used as the current time acquisition unit of the present invention, the power supply control unit 2602 is used as the power supply control unit, and the reception period receiving unit 2603 is used as the reception period reception unit.

The operation of the information receiving apparatus configured as described above will be described with reference to the flowchart of FIG.

At step 2701, it is determined whether or not power is to be supplied to the information receiving section and the additional information receiving section. In the additional information database, the next scheduled transmission date and time and reception period are accumulated for each notice keyword. The scheduled transmission date and time are compared with the current date and time acquired from the clock 2601, and if they match, the process proceeds to step 2702. Otherwise, step 2701 is repeated.

It should be noted that, depending on the form of the communication channel, the transmission time (the error between the transmission time and the reception time, ie, the time required for transmission) cannot be ignored. What is added to the above-described next scheduled transmission date and time may be transmitted as the next scheduled transmission date and time. By doing so, there is no need to provide a means for correcting the error on the receiving device side, and the configuration on the receiving device side can be simplified. Alternatively, a means for correcting the error may be provided in the receiving device in advance. As described above, in the case of the configuration in which the correction unit is provided on the receiving device side, the above-described transmission time is not added to the next scheduled transmission date and time transmitted from the transmitting device side.

In step 2702, power is supplied to the information receiving section and the additional information receiving section to start receiving information.
Also, measurement of the reception time is started.

In step 2703, the reception time is compared with the reception period of the additional information database, and if the reception time is shorter, step 2703 is repeated. If not, the process shifts to step 2704 to terminate power supply to the information receiving unit and the additional information receiving unit.

Note that, for example, the reception period cannot be predicted in advance depending on the form of the communication channel, such as a general public line. In such a case, a period calculated on the assumption that transmission is performed at the slowest communication speed may be transmitted as the reception period. In this case, an identifier indicating the completion of the transmission of the content information is added to the end of the content information. Then, the receiving device immediately stops power supply to the power information receiving unit 101 after receiving the identifier.

Further, separately from this, when the error between the transmission period and the reception period can be predicted in advance, and when the transmission period of the content information to be transmitted is transmitted from the transmission side, , The receiving device may be provided with the same prediction means as that described in the eighth embodiment.

As shown in FIG. 31, the additional information database stores the scheduled transmission date and time and reception period for specific information, and the next transmission scheduled date and time and reception period for each preview keyword.
The specific information is general information such as news or weather forecast. Such highly general information is considered to be often viewed by the user, and therefore must be received. Therefore, in the additional information database,
Save the scheduled transmission date and time and reception period for specific information. The information transmitting side periodically transmits the specific information.
Also, in order to reliably transmit the notice keyword to the information receiving side, the information transmitting side transmits the notice keyword simultaneously with the transmission of the specific information information.

The scheduled transmission date and time stored in the additional information database is compared with the current date and time obtained from the clock 2401, and if they match, the process moves to step 3002. Otherwise, step 3001 is repeated.

Note that, depending on the form of the communication channel, the transmission time (the error between the transmission time and the reception time, ie, the time required for transmission) cannot be neglected. In such a case, the transmission time is reduced. What is added to the above-described next scheduled transmission date and time may be transmitted as the next scheduled transmission date and time. By doing so, there is no need to provide a means for correcting the error on the receiving device side, and the configuration on the receiving device side can be simplified. Alternatively, a means for correcting the error may be provided in the receiving device in advance. As described above, in the case of the configuration in which the correction unit is provided on the receiving device side, the above-described transmission time is not added to the next scheduled transmission date and time transmitted from the transmitting device side.

The steps 3002 to 3011 are
