BACKGROUND OF THE INVENTION
  The present invention can be used, for example, when receiving information transmitted from an information transmission apparatus via a digital broadcasting system, a public telephone line, or the like., EmotionThe present invention relates to an information receiving device.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, information such as moving images, still images, sounds, characters, programs, and the like has been exchanged using public lines, such as the Internet and personal computer communication. However, in either case of the Internet or personal computer communication, the information recipient takes the form of accessing the source of information and selecting (downloading) necessary information from the storage device of the source. Therefore, the receiver cannot obtain information without performing any action on the information sender. That is, information cannot be obtained by a simple operation such as selecting a channel as in general television broadcasting. Thus, in an information communication system that requires an operation on the receiver side, it cannot be used as an information communication means for advertising or public information.
[0003]
Therefore, in recent years, in response to such issues of multimedia information communication, whether or not information is needed on the recipient side (each household) by accessing a large number of recipients who want to receive information from public sources via public lines. The information is sent to the receiver side and stored on the receiver side regardless of the receiver, and the receiver side selects the display operation of the data storage device (that is, the data reception device), for example, a television broadcast channel. An information communication system is proposed in which information is displayed on a screen by the same operation as selection.
[0004]
In addition, with the development of digital technology, digital broadcasting systems in which various information including broadcast signals are digitized are being researched and developed in the broadcasting industry. As such a system, an integrated digital system (referred to as an ISDB (Integrated Services Digital Broadcasting) system) is known. In the ISDB system, multimedia information is digitized, and these are integrated and transmitted, and in addition to these pieces of information, additional information used as control information on the receiving side is also transmitted simultaneously. Can do.
[0005]
Therefore, if the system as described above is used, a service for transmitting various information such as news, sports, weather forecast, leisure information, and program related information can be realized.
[0006]
[Problems to be solved by the invention]
However, in the configuration as described above, when a large amount of information is transmitted due to an increase in communication capacity of the public line or use of a means having a wide bandwidth such as digital broadcasting, the information is browsed by the receiving device. In such a case, there arises a problem that the information that the user wants cannot be searched efficiently. Further, the information providing side adds a keyword to the transmission information or transmits a transmission schedule in advance in response to a request for the user to continuously browse. Japanese Patent Laid-Open No. 8-263410 proposes a method of selecting information by designating a keyword for information desired on the receiving side and collating with a keyword added to the received information. However, there is a problem that the reception keyword alone prevents browsing of information other than the specified information even on the receiving side, and the opportunity to discover new information is reduced, and the transmitting side cannot expect an increase in new users.
[0007]
On the other hand, in recent years, an increase in power consumption of the receiving terminal has become a problem, and there is an increasing demand for suppressing the power consumption of the receiving device while unnecessary information is being transmitted to the user. There was a problem that the increase in power could not be suppressed.
[0008]
  In consideration of the above-described conventional problems, the present invention can obtain the content of information scheduled to be transmitted with a time delay with a smaller amount of information than in the past.FeelingAn object of the present invention is to provide an information receiving device.
[0009]
  In addition, the present invention takes into consideration the above-described problems of the prior art, and an information receiving apparatus capable of suppressing power consumption compared with the prior art.PlaceThe purpose is to provide.

The hardware configuration of this embodiment is shown in FIG. Note that FIG. 28 is basically the same as the configuration of a general-purpose computer system, to which a receiving means for receiving satellite digital broadcast is added.
[0063]
The operation of the information receiving apparatus configured as described above will be described with reference to the flowchart of FIG.
[0064]
In step 201, the received data is decoded. The satellite wave received from the receiving antenna is assembled into a packet from the stream, and further reconstructed from a plurality of packets to a data unit (for example, a file, a program, etc.). After decryption, the identifier added with the data is determined, and the process proceeds to step 202 in the case of a notice keyword and to step 203 in the case of content information. Note that the above-described determination of the identifier is performed by both the information receiving unit 101 and the additional information receiving unit 102. This is because, in any channel, various data may be multiplexed, and it is necessary to determine the identifier after assembling the packet. Examples of multiplexed data include notifications from broadcasting stations and data of other services such as karaoke.
[0065]
In step 202, the received information synthesizing unit 103 performs processing for displaying the notice keyword on the display unit at the same time as the received information. In the present embodiment, it is assumed that the received information is described in HTML (Hyper Text Markup Language) and is viewed by a dedicated browser. Assume that the received notice keyword is shown in FIG. In this case, an HTML file shown in FIG. 4A is created from the notice keyword, and a new file as a base for synthesis shown in FIG. 4C is further created.
[0066]
In step 203, the received information combining unit 103 performs processing for displaying the content information on the display unit at the same time as the notice keyword. In order to synthesize with the base file prepared in step 202, the file name is changed as shown in FIG.
[0067]
In step 204, the display unit 104 displays content information and a notice keyword. Information is browsed using an HTML browser. In step 202 and step 203, since the content information and the notice keyword are combined and displayed using the HTML frame tag, the base file shown in FIG. 4 (c) is displayed. The user can view the notice keyword simultaneously with the content information. A display example is shown in FIG.
[0068]
As described above, the user can check the contents of the information scheduled to be transmitted next time when viewing the received information.

The satellite wave received from the receiving antenna is assembled into packets from the stream, and further reconstructed from a plurality of packets into data constituent units (for example, files, programs, etc.). The reconstructed data does not necessarily include the notice keyword. For example, when information is composed of text, images, and sound, adding a notice keyword to each component wastes communication capacity. Therefore, a notice keyword is added to a representative component. Whether or not a notice keyword is added is determined by an identifier. If it is added, the process proceeds to step 702. If not, the process proceeds to step 705.
[0078]
In 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 head to know the size of the notice keyword. Thereafter, the notice keyword is separated by reading out the data of the size of the notice keyword read from the read place. An example of the data structure is shown in FIG. In FIG. 8, reference numeral 801 is assigned to the area for storing the information on the keyword size, 802 is assigned to the storage area for the notice keyword, and reference numeral 803 is assigned to the area to store the content information.

(Embodiment 8)
  Next, the present inventionInventions related toAs an embodiment, an information receiving apparatus using satellite digital broadcasting is shown.
[0144]
  FIG. 24 shows the present invention.Inventions related toIt is a system configuration figure concerning the 8th embodiment. FIG. 24 includes the same parts as the system configuration of the fifth embodiment of the invention shown in FIG. 16, and therefore, the same reference numerals are given to those parts and description thereof is omitted, and only different parts will be described.
[0145]
In the figure, reference numeral 2401 denotes a clock for acquiring the current time, and 2402 denotes a power supply control unit that controls 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 if they match, the power supply control unit 2402 It is a means to supply. Reference numeral 2403 denotes a reception period reception unit that receives information about a period during which content information transmitted from a transmission station is received on the reception side (hereinafter referred to as a reception period). The information about the reception period sent from the transmitting station side may include information for specifying the broadcast channel of the content information (for example, broadcast program).
[0146]
  Note that each of the above-described components is the clock 2401 according to the present invention.Inventions related toPower supply systemMibe2402 corresponds to power supply control means, and the reception period reception unit 2403 corresponds to reception period reception means.
[0147]
The operation of the information receiving apparatus configured as described above will be described with reference to the flowchart of FIG.
[0148]
In step 2501, it is determined whether to supply power to the information receiving unit 101. As shown in FIG. 31, the additional information database 901 stores the next transmission scheduled date and time and the 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. If not, step 2501 is repeated.
[0149]
Depending on the form of the communication path, the transmission time (the error between the transmission time and the reception time, that is, the time required for transmission) cannot be ignored. In such a case, this transmission time is described above. What is added to the next scheduled transmission date and time may be transmitted as the next scheduled transmission date and time. By doing so, it is not necessary to provide a means for correcting the error on the receiving device side, and the configuration on the receiving device side can be simplified. In addition to this, it is of course possible to adopt a configuration in which means for correcting the error is provided in advance in the receiving apparatus. As described above, in 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 transmission scheduled date and time transmitted from the transmitting device side.
[0150]
In step 2502, power is supplied to the information receiving unit 101 according to an instruction from the power supply control unit 2402, and information reception is started. Also, measurement of reception time in the information receiving unit 101 is started.
[0151]
  In step 2503, the power supply control unit 2402 compares the reception time with the reception period received by the reception period reception unit 2403 and then sent to the additional information database 901 and recorded. If the reception time is shorter than the reception period, step 2503 is repeated. If not, the process proceeds to step 2504, and the power supply to the information receiving unit 101 is terminated.
  Note that the reception period may not be predicted in advance depending on the form of the communication path, such as a general public line. In such a case, a period calculated assuming transmission at the slowest communication speed may be transmitted as the reception period. In that case, an identifier representing completion of transmission of the content information is added to the end of the content information. The receiving device receives the identifier and immediatelyLoveThe power supply to the information receiving unit 101 is stopped.
[0152]
In addition, when the error between the transmission period and the reception period can be predicted in advance and the transmission period of the content information to be transmitted is configured to be transmitted from the transmission side, the reception is performed. What is necessary is just to provide the following prediction means in an apparatus. That is, the predicting means is a means for processing a period in which correction according to the state of the communication path is added to the transmission period previously received by the receiving apparatus as the above-described reception period. Of course, the transmission may be performed in consideration of the error on the transmission side in advance.
[0153]
In step 2504, the received data is decoded. The satellite wave received from the receiving antenna is assembled into a packet from the stream, and further reconstructed from a plurality of packets to a data unit (for example, a file, a program, etc.). After the decryption, the identifier added with the data is determined, and in the case of additional information, the process proceeds to step 2505, and in the case of information, the process proceeds to step 2506.
[0154]
In step 2505, the received additional information is stored in the additional information database. The additional information is composed of a classification item, a content keyword, a notice keyword, a 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.
[0155]
In step 2506, the reception information received by the information receiving unit 101 is stored in the reservation information database 1604.
[0156]
Steps 2507 to 2511 perform the same processing as steps 1705 to 1709 of the fifth embodiment of the invention.
[0157]
As described above, the amount of power required for information reception is reduced.
[0158]
In the eighth embodiment, satellite digital broadcasting is used as the communication means. However, public telephone lines, CATV lines, and terrestrial broadcasting may be used. Further, different communication means may be used in the information receiving unit, the additional information receiving unit, and the reception period receiving unit.
[0159]
Further, the reception period may consist of the arrival time of information and the time when reception ends.
[0160]
Needless to say, it is possible to acquire information using the arrival time and reception period of information without using the power supply control means.
[0161]
In this embodiment, the keyword comparison unit 1603 is not provided. However, the present invention is not limited to this. For example, the keyword comparison unit 1603 described in FIG.
