[0023]
The transmission process of the recording reservation information will be described with reference to the flowchart of FIG. First, a user determines a communication destination to which reservation information is to be transmitted (step S1). For example, an operation such as displaying a reservation information transmission menu (not shown) on the display screen of the monitor 17 and determining a desired transmission destination from a list of communication destinations registered in advance, such as a community, is performed. Here, after the TV program recording device 2 is determined as a communication destination, the TV program recording device 1 is connected to the network 3 through the network transmitting / receiving device 12 so that communication with the TV program recording device 2 is possible.
[0024]
At this time, in the process of step S2, if it is determined that communication with the previously selected communication destination is not performed, whether to search for another communication destination is selected (step S3), and if another new communication destination is to be searched, Returning to step S1, a communication destination is selected. Here, when another communication destination is not searched for, the transmission processing of the recording reservation information ends.
[0025]
The television program recording device 2 selected as the communication destination in the process of step S2 returns a communication request from the television program recording device 1 as to whether or not to permit the communication. The TV program recording device 1 receives the reply from the TV program recording device 2 and determines whether communication is permitted or not (step S4). When the communication is permitted, the recording reservation information of the TV program recording device 2 of the communication destination is obtained (step S5). If the communication is not permitted, the process returns to step S3 to determine whether to search for another communication destination.
[0026]
After obtaining the reservation information of the communication destination, for example, the information is compared with the reservation information in its own reservation information database, and it is checked whether the other party is also scheduled to record the television program to be prerecorded. 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 recorder 2 (step S7).
[0027]
At this time, if it is determined in the process of step S7 that the previously determined reservation information is not to be transmitted, whether to transmit another reservation information is selected (step S8), and another reservation information is newly transmitted. If it is, the process returns to step S6 to select the reservation information to be transmitted. If another reservation information is not transmitted, the process returns to step S3 to search for another communication destination.
[0028]
When the reservation information is sent, the communication destination replies whether or not to permit the reception of the reservation information. It is determined whether or not it has been sent properly (step S9). If the transmission permission information is sent, the transmission is successful (step S10), and if the non-permission information is sent, the transmission is failed (step S11). Thereafter, the process returns to step S8 to determine whether to transmit another reservation information.
[0029]
Thus, the recording reservation information is transmitted from the television program recorder 1 to the television program recorder 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 transmission of the reservation information may be automatically transmitted periodically to the registered communication destination.
[0030]
On the other hand, a case where recording reservation information is received from an external device will be described. For example, assume that the television program recorder 1 receives recording reservation information from the television program recorder 2. At this time, it is assumed that the other party's TV program recording device 2 is connected to the network.
[0031]
The transmission process of the recording reservation information 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 the reservation information (step S21). For example, an operation such as displaying a reservation information receiving menu (not shown) on the display screen of the monitor and determining a desired receiving destination from a communication destination list registered in advance is performed. Here, after the TV program recording device 2 is determined as a communication destination, the TV program recording device 1 is connected to the network 3 through the network transmitting / receiving device 12 so that communication with the TV program recording device 2 is possible.
[0033]
At this time, if it is determined in the process of step S22 that communication with the previously selected communication destination is not to be performed, whether or not to search for another communication destination is selected (step S23). , And returns to step S21 to select a communication destination. Here, when another communication destination is not searched, the recording reservation information receiving process ends.
[0034]
The television program recording device 2 selected as the communication destination in the processing of step S22 returns a response to the communication request from the television program recording device 1 as to whether or not to permit the communication. The TV program recording device 1 receives the reply from the TV program recording device 2 and determines whether communication is permitted or not (step S24). When the communication is permitted, the recording reservation information of the TV program recording device 2 of the communication destination is obtained (step S5). If the communication is not permitted, the process returns to step S23 to determine whether to search for another communication destination.
[0035]
When the reservation information of the communication destination is obtained, for example, the reservation information is compared with the reservation information in its own reservation information database, and what kind of television program the other party is to perform reservation recording is checked. Information is determined (step S26). When the reservation information to be received is determined, the reservation information is received from the television program recorder 2 (step S7).
[0036]
At this time, if it is determined in the processing of step S27 that the previously determined reservation information is not received, whether to receive another reservation information is selected (step S28), and another reservation information is newly received. If so, the process returns to step S26 to select the 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]
At the communication destination, when a transmission request for the reservation information is sent, the communication destination returns a response as to whether or not the transmission of the reservation information is permitted. It is determined whether transmission of the 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 failed (step S31). Thereafter, the process returns to step S28, and it is determined whether or not 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 reception of the reservation information may be automatically received periodically from the registered communication destination.
[0039]
The recording reservation information held by the TV recorder is held as the following information in the reservation information database of the TV program recorder. However, the recording reservation information that is not disclosed (not disclosed) by the following public information 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 should be hidden from others, it can be kept secret.

[0042]
Next, by sharing the above-described recording reservation information, the recording reservation of the television program is performed by each of the television program recording apparatuses. It becomes possible to hold data obtained by recording a program. In this situation, the TV recorders 1 and 2 exchange information about their own recorded data and, when holding the same TV program, use the recorded data to perform shared viewing operations such as playback and pause.
[0043]
However, in the following cases, there is a possibility that the recording data held by 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 television program recording device 1 is disclosed in five programs, while the recording information retained in the television program recording device 2 is one non-disclosed program and three disclosed programs. Among these, two programs that can be shared and viewed are "2003/3/9 16:07:00 to 17:45 sports" and "2003/3/9 21:00 to 21:54 variety". The two programs are extracted as recording information that can be shared and viewed, and are displayed on monitors connected to the respective TV program recording devices. At this time, if the television program held by either of the television program recording devices is kept private, the common viewing operation is disabled even if the common television program is recorded. Even if the recording start time and the end time do not match, if there is a partly overlapping time zone, the recording information is set as the recording information that 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 held by the other TV program recording device 1 is a part of the recording data of the same program held by the other TV program recording device 2, the common portion (Time zone), a shared viewing operation can be performed.
[0046]
FIG. 7 is a sequence diagram of the shared viewing operation. According to the operation of the user using each device, the content of the operation is transmitted to the other device, and the operation is executed on the receiving side.
[0047]
First, a network such as P2P is established between the television program recorder 1 (device 1) and the television program recorder 2 (device 2). For example, the user desires to operate the recorded 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 using 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 permission of the shared viewing operation is obtained from the device 2, exchange of recorded program information (recording information) is performed. At this time, at the same time that the device 2 returns a permission signal for permitting the shared viewing operation, the recording information is automatically transmitted to the device 1, and the device 1 receives the recording information together with the permission signal, and It is conceivable to send it to 2.
[0049]
After exchanging the recorded program information, transmission / reception of the shared viewing operation command is performed. As shown in FIG. 5, recording information that can be shared and viewed is acquired from both recording information, and is displayed on the display screen of the monitor. Then, the user selects recording information to be shared and viewed. 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 in ordinary individuals, such as reproduction, end, fast forward, rewind, pause, jump (to a specific time), etc., of the program selected in this way can be performed from the apparatus 1 by the apparatus 2. This can be performed in common for both TV program recorders.
[0050]
Since such a common viewing operation is performed on the screen, for example, when a certain scene is being watched, a situation in which the viewer is suddenly fast-forwarded by the operation of the other party and a situation in which the viewer cannot calmly watch occurs. Is also conceivable. As a method of alleviating such a situation, a method of common viewing while talking on the telephone can be considered. For example, if a common operation is performed by saying, "Hey, fast forward this scene.", The other party can recognize that the operation has been performed in advance, so that a situation in which the operation is suddenly performed can be avoided. Furthermore, if you use a videophone or the like and display the other party's face in the corner of the display screen displaying the recorded program, you will get the feeling of watching together in the same room, Expect more natural shared viewing.
[0051]
When ending the shared viewing operation, for example, when the device 2 notifies the end of the shared viewing operation, the device 1 is notified of the end of the shared viewing operation by a user operation. The device 1 that has received this returns a response as to whether or not to permit the device 2 to end. If permitted, the shared viewing operation ends, and if not, the shared viewing operation continues. It should be noted that the shared viewing operation may be terminated when the device 2 requests to end the shared viewing operation.
[0052]
Further, by applying this example, it is conceivable to determine a television program to be recorded by using the information of the user's hobbies and preferences held in the user's preference database 7. For example, the reservation information and / or the recording information in a certain TV program recorder can show the user's taste and taste. The analysis result of the reservation information and / or the recording information is stored in the preference database 7. Then, information in the preference database of the user of each television program recording device is collected in 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 to obtain program information such as "the program with the most reservations" or "the program reserved by a person who has similar hobbies and preferences". . Alternatively, by registering information on one's hobbies and preferences and displaying information on hobbies and preferences together with a user name when selecting a communication destination, a person who has similar hobbies and preferences can be displayed. Alternatively, information such as a program reserved by that person can be obtained.
[0053]
As described above, according to the present example, the recording reservation information held in the own TV program recording device is sent to the other party's TV program recording device, and the common recording program is shared by sharing the recording reservation information. Record and share. As a result, a common topic regarding the television program can be created, or the user can simultaneously view and enjoy the program through shared viewing.
[0054]
In addition, by holding the recording data of the same television program in each television program recording device on the network, a shared viewing operation without infringing copyright can be realized.
[0055]
Further, by exchanging not the recording data of the TV program itself but the recording reservation information or the recording information relating to the recording data as the shared information, it is possible to realize an exchange with a low load.
[0056]
Furthermore, by statistically processing the reservation information and / or the 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 similar taste and interest can make a reservation. Information such as a program that is running can be extracted, and an additional information providing service can be realized.
[0057]
The broadcast form of a television broadcast program to be recorded in the present invention may be a broadcast form in which program contents are distributed via a network such as an analog broadcast television, a digital broadcast television, a satellite broadcast, a cable television, or the Internet. Good.
[0058]
Further, the present invention is not limited to the above-described embodiment, and it goes without saying that various other configurations can be adopted without departing from the gist of the present invention.
[0059]
【The invention's effect】
According to the present invention, the reservation recording information of the television broadcast program held by the own device is transmitted to the partner device that wants to share the television broadcast program information, and the desired television broadcast is transmitted to the partner device. Since the program is recorded, the own device and the partner device can have the recording data of the same television broadcast program. As a result, it is possible to prevent the user from forgetting to record the video, to create a common topic regarding the television broadcast program, and to achieve an effective communication.
[0060]
According to the present invention, the recording data recorded in the own device and the recording data recorded in the partner device are exchanged and compared, and if there is duplicate recording data, the duplicate recording data is transmitted via the network. It is possible to simultaneously operate the recording data of the user and the recording data of the other party. As described above, by holding the recording data of the same television broadcast program in each device on the network, there is an effect that the shared viewing operation without infringing the copyright can be realized.
