The user of the television playback device 32 accepts or selects the play message I2. After accepting the play message I2, the preset time may be designed to wait from the time of the selection (mainly in the display time in the operating system) to the time of the program playing in the television program list. Or directly and explicitly correspond to the time when the system displays the time, and can be presented as the broadcast time of the previewed TV program, the first and second television broadcast devices 31, 32 will automatically adjust the frequency to the specified The television channel with the appointment, that is, the second television broadcast device 32 and the first television broadcast device 31, can simultaneously receive and reserve the television program for any time period predicted in the television program tables T1, T2. In this way, under the continuous operation of their respective TV playback devices, the playback settings that are reserved for each other will not be missed or forgotten, and there is no need to perform any channel search operation; the operation only needs to arrive at the time specified by the device. The channel adjustment is automatically made so that the user who accepts the invitation can actually watch the same TV show with the user who sent the invitation.

The contact lists L1, L2 used in the first embodiment are generated by each of the television broadcast apparatuses in the system registering the central server 20 via the communication network 30 and being authenticated by the central server 20. The different user identities corresponding to the different television playing devices displayed in the contact lists L1 and L2 can provide the user terminal for further understanding in a specific manner; for example, the central server 20 can provide a website or a The user interface can further classify or edit the identity of each registered user, so that the user can find the same and even know each other and contact each other.

In addition to the foregoing production methods, another preferred method of production is to allow the user to search and edit the contact list required by himself. Similar to the design of some instant messaging programs, it is necessary to leave an email address at the same time for registration of the user identity, and other members of the television program sharing and playing system 200 of the present invention can be based on the electronic device of the device. All email addresses in your contacts are used to identify the identity of users who may be known to you in their system. Therefore, users on any TV broadcasting device can use their contact list to find the friends they are knowing or who they want to contact. In turn, they can send invitations to complete the same TV program through the above-mentioned implementation. Sharing purpose.

In combination with the aforementioned simultaneous subscription play and self-editing of the contact list, the display of each user identity of the contact list of the present invention may also include a television broadcast device having an unconnected state. Although the unwired TV player cannot issue a sharing invitation for common instant play, the TV program scheduled to be broadcast on the TV program list can still provide the user who issued the invitation and the user who accepts the invitation. Play and watch the reservation mode. In detail, when the user accepting the invitation starts to operate the television playing device, or when the user completes the connection state, the player can receive the playing invitation signal and display the playing message. If the scheduled TV program time can be matched, after receiving or selecting the broadcast message, the corresponding TV program can be played at the preset time specified. Among them, the part of the temporary storage or transmission of the message in the offline state can be completed by using the technology of the current instant messaging program, and will not be described in detail in the present invention.

In addition, each user identity in the contact list used in the first embodiment can be obtained by having a designated television player or a television card or the like, but this may reduce the user's viewing. Sharing results. Therefore, in the second embodiment of the present invention, the member or the receiving end that does not have the registered login identity of the present invention can be also used based on the above-described technology, except that the generation of the contact list can be edited by the user. The television broadcast device edits its corresponding email address to the contact list of the invitation side. In the system of the present invention, the function of inviting friends to share and watch television programs together can be more complete.

This second embodiment can be further referred to the system diagram of the second figure. In this example, the user of the first television broadcasting device 31 is also one of the invitations, and the user of the second television broadcasting device 32 is the one who accepts the invitation. However, the second television broadcast device 32 of this example does not have the identification data for identity management, such as the registered account and the login password, so that the device cannot be connected to the communication network 30. The central server 20 is connected. However, the first television broadcast device 31 can still communicate with the second television broadcast device 32 via the communication network 30 in a conventional manner, such as an e-mail, an instant messaging program, or the like.

As described above, the contact list L1 in the first television broadcasting device 31 can be self-edited. In this example, the user of the first television playback device 31 is aware of the email address corresponding to the user of the second television playback device 32; therefore, in its contact list L1, it corresponds to the format of the email address. The second user identity is added. Therefore, with the design of this embodiment, when the first television broadcast device 31 is in operation, the display of the contact list L1 to which it belongs may include the members having the login identity, and may also include the user's knowledge. Other friends who are not members. Allow users to have more choices when sharing TV shows.

However, as described above, the television program sharing and playing system 200 of the present invention is designed as a platform mechanism for performing file exchange; in other words, by means of a fixed network link address, the system can have an invitation function. A television playing device can provide a television broadcaster accepting the invitation to download the file via the communication network 30 while continuously operating and staying connected.

Therefore, in this example, when the first television broadcast device 31 issues the play invitation signal to the second television broadcast device 32, it is necessary to simultaneously share the television program to be watched, for example, on the first television broadcast device 31. The TV program being played is recorded in the file. The file of the television program that has been recorded is stored in the first television broadcasting device 31. The manner in which the play invitation signal is sent by the first television broadcast device 31 of this example is similar to that of the first embodiment described above, that is, according to the second user identity in the displayed contact list L1. Since the second user identity is presented in the form of an email address, the play invitation signal is sent in the form of an email, and the play invitation signal (ie, the sent email) is automatically included. The play message I2, in addition to the preset invitation statement, for example: "Would you like to download or play the TV program recommended by the user of the first television broadcast device 31?", the play message I2 also contains A play link address (which can be a URL type) corresponding to the recorded file of the TV program.

As described above, if the user of the second television broadcast device 32 has the will, the play link address of the play message I2 is accepted or selected. After receiving the play message I2, the preset time may also be designed to be separated from the time when the time interval is 0, that is, the user of the second television playing device 32 accepts the invitation. And select the moment when the link address is played. In this example, the accepting inviter can choose to download the file to its own device for viewing, or to view it online on its device. The manner of viewing may be to generate a browsing webpage (not shown in the drawing) and have a corresponding screen window and a user interface, so that the second television playing device 32 can directly connect to the first television playing device 31 to Online playback and viewing of the recorded TV program files. In this way, the sharing invitation application of the present invention can also be performed for a client in the system that does not have the login identity.
