[0021]
Next, a case where recording reservation information is transmitted to an external device will be described. For example, it is assumed that recording reservation information is transmitted from the television program recording device 1 to the television program recording device 2. At this time, it is assumed that the counterpart TV program recording apparatus 2 is connected to the network.
[0022]
The recording reservation information to be transmitted is composed of the following information, for example. By adding a sender comment to the program information, the image of the data can be thought of on the receiving side. In addition, it is convenient to be able to set information to be transmitted each time, such as adding recording mode information.

[0023]
The recording reservation information transmission process will be described with reference to the flowchart of FIG. First, the user determines a communication destination to which reservation information is to be transmitted (step S1). For example, a reservation information transmission menu (not shown) is displayed on the display screen of the monitor 17, and a desired transmission destination is determined from a list of communication destinations registered in advance such as a community. Here, after the television program recording device 2 is determined as the communication destination, the television program recording device 1 is connected to the network 3 through the network transmitting / receiving device 12 so as to be communicable with the television program recording device 2.
[0024]
At this time, if it is determined in step S2 that communication with the previously selected communication destination is not performed, whether or not to search for another communication destination is selected (step S3), and a new communication destination is newly searched. Returning to step S1, the communication destination is selected. Here, when another communication destination is not searched for, the recording reservation information transmission processing ends.
[0025]
The television program recording device 2 selected as the communication destination in the process of step S2 replies whether communication is permitted or not in response to the communication request from the television program recording device 1. The television program recording device 1 receives the reply from the television program recording device 2 and determines whether communication is permitted / not permitted (step S4). When the communication is permitted, the recording reservation information of the television program recording device 2 of the communication destination is acquired (step S5). If communication is not permitted, the process returns to step S3 to determine whether to search for another communication destination.
[0026]
Once the reservation information of the communication destination is obtained, for example, the information is compared with the reservation information in its own reservation information database, and it is checked whether or not the other party is also scheduled to record the TV program to be recorded. The reservation information to be transmitted is determined (step S6). When the reservation information to be transmitted is determined, the reservation information is transmitted to the television program recording device 2 (step S7).
[0027]
At this time, if the previously determined reservation information is not transmitted in the process of step S7, whether or not to transmit another reservation information is selected (step S8), and another reservation information is newly transmitted. For example, the process returns to step S6 to select reservation information to be transmitted. When other reservation information is not transmitted, the process returns to step S3 to search for another communication destination.
[0028]
When the reservation information is sent to the communication destination, it returns whether or not the reception of the reservation information is permitted. It is determined whether it has been sent properly (step S9). If the transmission permission information is sent, the transmission is successful (step S10). If the non-permission information is sent, the transmission is failed (step S11). Thereafter, the process returns to step S8 to determine whether or not to send another reservation information.
[0029]
In this way, the recording reservation information is transmitted from the television program recording device 1 to the television program recording device 2. When the television program recording device 2 permits the reception of this information, the television program recording device 2 records the television program according to the information. Alternatively, the reservation information may be automatically transmitted periodically to the registered communication destination.
[0030]
On the other hand, a case where the recording reservation information is received from an external device will be described. For example, it is assumed that the television program recording device 1 receives recording reservation information from the television program recording device 2. At this time, it is assumed that the counterpart TV program recording apparatus 2 is connected to the network.
[0031]
The recording reservation information transmission process will be described with reference to the flowchart of FIG. In FIG. 4, the processing from step S21 to step S25 is substantially the same as the processing from step S1 to step S5 in FIG.
[0032]
First, the user determines a communication destination to receive reservation information (step S21). For example, a reservation information reception menu (not shown) is displayed on the display screen of the monitor, and an operation is performed such as determining a desired reception destination from a list of communication destinations registered in advance. Here, after the television program recording device 2 is determined as the communication destination, the television program recording device 1 is connected to the network 3 through the network transmitting / receiving device 12 so as to be communicable with the television program recording device 2.
[0033]
At this time, if it is determined in step S22 that communication with the previously selected communication destination is not performed, whether or not to search for another communication destination is selected (step S23), and another communication destination is newly searched. Returning to step S21, the communication destination is selected. Here, when another communication destination is not searched for, the recording reservation information receiving process ends.
[0034]
The television program recording device 2 selected as the communication destination in the process of step S22 returns whether or not to permit communication in response to the communication request from the television program recording device 1. The television program recording device 1 receives the reply from the television program recording device 2 and determines whether communication is permitted / not permitted (step S24). When the communication is permitted, the recording reservation information of the television program recording device 2 of the communication destination is acquired (step S5). If communication is not permitted, the process returns to step S23 to determine whether to search for another communication destination.
[0035]
Once the reservation information of the communication destination is acquired, for example, the information is compared with the reservation information in its own reservation information database, and the TV program that the other party is scheduled to record is checked and received. Information is determined (step S26). When the reservation information to be received is determined, the reservation information is received from the television program recording device 2 (step S7).
[0036]
At this time, if the previously determined reservation information is not received in the process of step S27, whether or not to receive another reservation information is selected (step S28), and another reservation information is newly received. For example, the process returns to step S26 to select reservation information to be received. If no other reservation information is received, the process returns to step S3 to search for another communication destination.
[0037]
When the transmission request for the reservation information is sent at the communication destination, it is configured to send back whether or not the transmission of the reservation information is permitted. It is determined whether transmission of reservation information is permitted (step S29). If the transmission permission information is sent, the reception is successful (step S30), and if the non-permission information is sent, the reception is unsuccessful (step S31). Then, it returns to step S28 and it is judged whether another reservation information is received.
[0038]
Thus, the television program recording device 1 acquires the recording reservation information held by the television recording device 2, and records the television program using the information. Alternatively, the reservation information may be automatically received periodically from the registered communication destination.
[0039]
The recording reservation information held by the television recording device is held as the following information in the reservation information database of the television program recording device. However, the recording reservation information that is not disclosed (not disclosed) by the public information shown below does not respond to an acquisition request from another television program recording device by this operation. Thereby, for example, when there is recorded data that is desired to be hidden from others, it can be made private.

Next, as a result of performing the recording reservation of the TV program by the respective TV program recording devices by sharing the recording reservation information described above, the same TV is recorded in the recording data recording devices of the TV program recording devices 1 and 2. It becomes possible to hold data in which a program is recorded. Under this circumstance, the television recording apparatuses 1 and 2 exchange information regarding the recording data of each, and when holding the same television program, perform the shared viewing operation such as playback and pause using the recorded data.
[0043]
However, in the following cases, there is a possibility that the recorded data of each other does not match.
・ Recorded data recorded directly
・ Recording with reservation information not shared
・ Recording by scheduled recording shared with another person
・ In addition, when recording data is deleted
[0044]
FIG. 5 is a diagram showing acquisition of recording information that can be shared and viewed. For example, in this example, the recording information held by the TV program recording apparatus 1 is five programs that are publicly disclosed, while the recording information that the TV program recording apparatus 2 holds is a secret one program and three public programs. Among them, the two programs that can be shared and viewed are “2003/3/9 16: 0 to 17:45 Sports” and “2003/3/9 21: 0 to 21:54 Variety”. The two programs are extracted as the recording information that can be shared and viewed and displayed on monitors connected to the respective TV program recording apparatuses. At this time, if a television program held by one of the television program recording devices is not disclosed, the common viewing operation is not possible even if a common television program is recorded. Even if the recording start time and end time do not match, if there is a partially overlapping time zone, the recording information can be shared and viewed.
[0045]
FIG. 6 shows an example of recorded data that can be shared and viewed. As shown in the figure, when the recording data of a certain program possessed by the other television program recording apparatus 1 is a part of the recording data of the same program possessed by the other TV program recording apparatus 2, the common part thereof Shared viewing operation can be performed for (time zone).
[0046]
FIG. 7 is a sequence diagram of the shared viewing operation. In accordance with the operation of the user who uses each device, the operation content is transmitted to the other, and the receiving side executes the operation.
[0047]
First, a network such as P2P is established between the television program recording device 1 (device 1) and the television program recording device 2 (device 2). For example, the user desires to operate the recording data that can be shared and viewed by the other party, and requests the shared viewing operation from the device 1 to the device 2 through the operation panel or the like. In response to this request, the user of the device 2 returns permission / non-permission of the shared viewing operation to the device 1.
[0048]
Here, when the shared viewing operation permission is given from the device 2, the recorded program information (recording information) is exchanged. At this time, at the same time as returning a permission signal permitting the shared viewing operation on the device 2 side, the recording information is automatically transmitted to the device 1 side, and the recording information is received together with the permission signal on the device 1 side. It is possible to send to 2.
[0049]
After the recorded program information is exchanged, the shared viewing operation command is transmitted / received. As shown in FIG. 5, the recording information that can be shared and viewed is acquired from both recording information and displayed on the display screen of the monitor. Record information for shared viewing is selected from the list. For example, when a program to be shared and viewed is selected by a user operation of the device 1, a command is transmitted from the device 1 to the device 2, and the device 2 also selects the same program. Further, operations similar to those used by ordinary individuals, such as playback, end, fast forward, rewind, pause, jump (to a specific time), etc., of the program selected in this way can be performed from the device 1 as well. Can be performed on both TV program recording apparatuses.
[0050]
Since such a common viewing operation is performed on the screen, for example, when watching a certain scene, a situation may occur in which the viewer cannot calmly watch, such as suddenly fast-forwarding due to the other party's operation. Is also possible. As a method of alleviating such a situation, a method of common viewing while talking on the phone can be considered. For example, if a common operation is performed by saying, “Sometimes, this scene will be fast-forwarded”, the other party can recognize that the operation is performed in advance, so that it is possible to avoid a sudden operation. Furthermore, if you use a videophone or the like to display the other party's face in the corner of the display screen that displays the recorded program, you can feel as if you are watching together in the same room, More natural shared viewing can be expected.
[0051]
When ending the shared viewing operation, for example, when the end of the shared viewing operation is notified from the device 2 side, for example, the device 1 is notified of the end of the shared viewing operation by a user operation. Upon receiving this, the device 1 returns whether or not to permit the end to the device 2, and if it is permitted, the shared viewing operation is ended, and if it is not permitted, the shared viewing operation is continued. It should be noted that the shared viewing operation may be terminated when a request for termination of the shared viewing operation is received from the device 2.
[0052]
Furthermore, by applying this example, it is conceivable to determine a television program to be recorded using information on the user's hobbies and preferences held in the user's preference database 7. For example, the user's hobbies and preferences are known from reservation information and / or recording information in a certain TV program recording apparatus. The analysis result of reservation information and / or recording information is stored in the preference database 7. Then, the information in the user preference database of each television program recording device is collected into a management server on the network of the community to which each user belongs and is made into a database. By doing so, for example, the user can access the management server and obtain program information such as “programs with the most reservations” and “programs reserved by people who have similar hobbies and preferences”. . Or, if you register your hobby preference information and select the communication destination so that the hobby preference information is displayed at the same time as the user name, the person who has a similar hobby preference to you In addition, information such as a program reserved by the person can be acquired.
[0053]
As described above, according to this example, the recording reservation information held in the own TV program recording apparatus is sent to the other party's TV program recording apparatus, and the recording reservation information is shared, so that a common TV program can be displayed. Record and share. Thereby, a common topic about the television program can be made, or it can be viewed and enjoyed simultaneously by shared viewing.
[0054]
Also, by holding recorded data of the same television program in each television program recording device on the network, a shared viewing operation without infringing the copyright can be realized.
[0055]
Further, as the information to be shared, the recording reservation information or the recording information related to the recording data, not the recording data of the TV program itself, can be exchanged with each other.
[0056]
Furthermore, by performing statistical processing on reservation information and / or recording information of each TV program recording device connected to the network, for example, a program with the most reservations or a person who has a hobby preference similar to that of the reservation is reserved. It is possible to extract information such as existing programs and to realize an additional information providing service.
[0057]
Note that the broadcast form of the television broadcast program to be recorded in the present invention may be a program content distributed via a network such as analog broadcast television, digital broadcast television, satellite broadcast, cable television, or the Internet. Good.
[0058]
Further, the present invention is not limited to the above-described embodiments, and various other configurations can be taken without departing from the gist of the present invention.
[0059]
【The invention's effect】
According to the present invention, reservation recording information of a television broadcast program held by its own device is transmitted to a partner device that wants to share television broadcast program information, and a desired television broadcast is transmitted to the partner device. Since the program is recorded, the recording data of the same television broadcast program can be held in the own device and the counterpart device. As a result, the user never forgets to record, has a common topic about the television broadcast program, and has an effect of being able to communicate well.
[0060]
  In addition, according to the present invention,Recording information including the distinction between disclosure / non-disclosure of recording data for each held program, recording time zone and programAnd the other deviceRecording information including the distinction between disclosure / non-disclosure of recording data for each held program, recording time zone and programReplace, compare andRecording information of a common program with at least a part of the recording time zone is extracted as recording information that can be shared and viewed, and when performing the extraction, even if it is a common program with a duplicate recording time zone, Programs that are not disclosed in the recording information are excluded as a common viewing operation and corresponding to the extracted recording informationWith respect to the recording data, it is possible to simultaneously operate the recording data of the own side and the recording data of the other party via the network. As described above, by holding recorded data of the same television broadcast program in each device on the network, there is an effect that a shared viewing operation without infringing the copyright can be realized.
