Definitions
- the invention relates to a method for operating a personalized broadcasting system, in which various program contents are sent to the users of the broadcasting system and certain users of the broadcasting system are assigned to specific user communities and community-specific for the users of the various user communities
- Program contents are automatically selected and / or generated from a large number of available program contents. Furthermore, the invention relates to a broadcasting system with a plurality of transmission channels for sending program content to terminals of users of the broadcasting system, with a number of program content sources, with at least one user community control unit, which assigns certain users to certain user communities, and with at least one program creation unit to select and / or generate community-specific program contents for the user communities, to which the respective users are assigned, from a large number of available program contents.
- a radio system is to be understood here as any system that is intended for its users, i. H. sent to the listener or viewer, preferably digital radio and / or television program content.
- the transmission of the program content can be wireless in any way, for example via terrestrial and / or satellite-based radio networks and / or wired, e.g. B. over broadband cable.
- User group profiles are created from the user profiles of the user groups. Special programs for the different user groups are then compiled by comparing the user group profiles with content profiles which were created for the individual program contents available These are then broadcast to the users of the respective user groups.
- This has the advantage that individual individual programs do not have to be created and sent for the individual users. Instead, it is assumed that the programs created for the respective user groups cover the individual wishes of the individual users in the groups relatively well, and consequently it is no longer necessary to create individual programs for the individual users.
- the disadvantage of such rim radio systems is that the user only
- radio systems that create a very individual, user-specific program for each user have the disadvantage that the probability is greatly reduced that two people who know each other have received and consumed the same program content.
- users generally prefer to receive a program tailored to their individual wishes, they generally do not want to be completely "isolated", but rather want to exchange information about the program content received with other people. A possible exchange with other people
- programs that are viewed or heard are an essential part of maintaining a user's interest in a radio program.
- This object is achieved by a method of the type mentioned in the introduction, in which, on the one hand, a user is assigned to a user community on the basis of a community assignment signal sent by the user.
- the term “signal” is to be understood here to mean any sign given by optical, acoustic, electrical or other technical means for the transmission of messages, information and, in particular, commands Program generates certain user-specific program contents and / or selected from a large number of available program contents and thereby integrates the community-specific program contents of a user community to which the user in question is assigned into the individual user-specific program. Since the assignment of the user to the user community is determined by the user himself and not automatically by the system without the user knowing this, the user has it in his own hand to consciously assign himself to certain user communities. He can go according to his own interests in certain areas, which are covered by the user communities, as well as which users from his environment, such as friends, colleagues, family members, have joined which user communities.
- the user can join several user communities and accordingly community-specific program content from different user communities to be integrated into the user-specific program of the user in question.
- the individual user is served with a user-specific program that has been individually put together for himself.
- the choice made by the user of the assignment to specific user communities can significantly increase the likelihood that he will receive certain program content, which is also consumed by other users with whom he can exchange information about the program content.
- the object is achieved by a radio system of the type mentioned at the outset, which has means for inputting a community assignment signal by the users and in which the user community control unit is designed in such a way that a user is assigned to a user community on the basis of the community assignment command sent by the user.
- the program creation unit must be set up in such a way that specific user-specific program contents are created and / or selected for the compilation of individual user-specific programs for the users, and the community-specific program contents of user communities to which the relevant user is assigned are integrated into the respective user-specific programs ,
- the individual, user-specific Programs compiled on the operator side for example within a central control unit (hereinafter simply referred to as "server") of the broadcasting system.
- server central control unit
- This version can therefore be referred to as a server-based variant.
- the user community control unit and the program creation unit are located in the server.
- the individual The user-specific program is then sent to the users concerned in each case via a program channel which is personally assigned to the user concerned, for example in coded form.
- the community assignment signal of a user to the user community control unit must be transmitted to the server via a retransmission channel.
- This retransmission channel can be a separate channel, for example a telephone line or an Internet connection etc. between a user's terminal and the server.
- the terminal can be the device with which the user receives the radio program, or a separate device such.
- This retransmission channel can also be used for the transmission of other signals or commands or data from the user side to the operator side.
- certain channels can also be kept free, which are used to send signals or commands or data back from the individual
- the various signals or commands can also be transmitted orally by telephone using a special service telephone number from the broadcasting system operator.
- a special service telephone number from the broadcasting system operator.
- the invention is not limited to this case.
- the individual, user-specific programs are only compiled within the end devices of the users.
- the individual program contents for compiling the individual program are preferably received by the respective end device in parallel over several transmission channels from the operator side.
- Received program contents can also be temporarily stored in the corresponding buffer in order to offer them to the user as selectable program contents at a given time - in addition to the program contents received at a specific point in time. This significantly expands the possibilities for individual program creation.
- the end devices of the users each have their own community control unit and / or their own program creation unit.
- community profiles are to be used to select program content and whether the community profiles are determined on the basis of the user profiles
- system architectures can also be implemented, which are based on a combination of the two basic variants, for example a broadcasting system in which the users' own program creation units are arranged in the end device and the server of the broadcasting system contains the user community control unit.
- the user community control unit e.g. the allocation of users to the user communities within the server.
- a common community profile can be created from the user profiles transmitted via retransmission channels from the terminals, which is transmitted back to the individual terminals for the program creation unit arranged there via suitable control data channels. The individual programs are then put together on the user side in the respective end device.
- the community assignment signal can be transmitted from the user to the user community control unit of the system in any manner and at any time. For example, when registering for the first time with the broadcasting system, the user can indicate within a questionnaire which serves as the basis for a user profile which user communities he would like to be assigned to. In this case, e.g. B. the community allocation signal within an application or
- Initialization data strings transmitted to the system can be assigned to a desired user community at any time by means of a corresponding community assignment signal. If the user community control unit is located in the end device of the user himself, a simple input of a corresponding command via a user interface of the end device is sufficient. Otherwise, the entered community assignment signal is forwarded from the terminal to the server via the return channel.
- a community membership request signal for this user community is sent from the operator side to a user possibly matching a user community.
- a positive response signal which in this case is the community assignment signal
- the user is assigned to the user community. I.e. the system automatically invites the user to join a specific user community that matches the interests of the respective user.
- a conformity value can be determined on the basis of a comparison of a user profile assigned to the user with a community profile assigned to a specific user community, which is a measure of the extent to which the profiles match.
- a conformity threshold is reached, the concerned users sent the community membership request signal.
- the user behavior of a user is analyzed and, depending on the user behavior, a community entry request signal is sent to the user concerned.
- a community entry request signal is sent to the user concerned.
- a typical example of this is a check whether, for example, a user regularly hears or sees a certain program. If there is a certain user community for this program, for example a fan club for this program, the user is offered to join this user group.
- the user preferably has the possibility at any time - for example within his user profile - to stipulate that he will not receive any requests to be assigned to any user communities.
- the actual assignment of the user to a user community takes place, for example, in that the user or an address of the user, which is required to send the program contents to the user, is entered in a user list in a community profile of the user community.
- the new user community is also entered accordingly in the user profile of the user.
- the community profile can also be updated taking into account the community-relevant parameters in the user profile of the new user.
- the system automatically creates a new user community.
- the system can e.g. B. automatically compare user profiles of different users with each other and / or with a created preliminary community profile in general or with regard to a certain criterion. On the basis of this comparison, users are then determined whose user profiles have a profile correspondence with the other user profiles and / or with the provisional community profile to a predetermined extent, at least with regard to one criterion.
- Community entry request signals for the planned user community are then sent out to the respective users. If necessary, this can only take place when a certain minimum number of potential community members has been reached. If enough If the user sends a positive response to the community membership request signal, ie a community assignment signal, the new user community is automatically created.
- the new user community is created at the request of a specific user.
- the user can send a user community constitution signal to the operator side.
- this user community constitution signal the user can u. a. Announce that he wants to create a user community and which topic this user community has as its content, for example whether it is a fan club for a certain series or a certain actor, singer etc. or one
- User community that has a special area of interest such as B. has a sport on the topic.
- the user in question who is the founder of the user community, can also determine whether it should be an open user community to which any other user can be assigned at any time, or a closed user community to which only those users can be assigned the founder himself or an "owner" of the user community (hereinafter referred to as "community representative") permits or explicitly invites them to do so.
- a community membership request signal for a specific user community is accordingly only sent to a user by the community representative or after a prompt by the community representative.
- an assignment of a user to the user community takes place on the basis of a community assignment signal sent by the user in question on his own initiative only after the approval of the community representative. Even with an open user community, it is possible that after
- the admission of a user to the desired user community is first checked.
- certain users or users with certain user profiles can join certain user communities, e.g. B. due to an age restriction.
- the broadcasting system In order to be able to work with user profiles or community profiles and content profiles, the broadcasting system must have appropriate analysis means for creating the user profiles on the basis of user information and, if necessary, for Creation of community profiles for the user communities based on the user profiles of the users assigned to the respective user community.
- the user information can, for example, be questions answered by the user or logged user behavior.
- the broadcast system requires analysis means to create content profiles for the
- the program creation unit has z. B. a program content selection unit, which selects program content for the user in question on the basis of a comparison of the content profiles with a user profile of a specific user or with a community profile of a user community.
- Various methods for creating user profiles from the user information various so-called cluster methods for forming community profiles on the basis of individual user profiles and methods for creating content profiles are known to the person skilled in the art, for example, from the above-mentioned document and the literature cited therein.
- the method according to the invention for forming user communities also offers additional advantageous possibilities.
- the user of a user community can send a program content, for example a specific video, radio play, etc. to the system.
- a program content for example a specific video, radio play, etc.
- he can also send a transmission proposal signal for a specific program content, which is made available to the broadcasting system from any program content source, to the system.
- the relevant program content is then integrated into the user-specific programs of at least some of the users of this user community.
- the system preferably checks beforehand whether the program content in question actually fits this user community.
- an assessment request signal can also be sent to the users of a user community who have received a certain program content in order to induce the users to send assessment data for this program content.
- a community preference value can then be determined on the basis of the assessment data returned by the users. I.e. a so-called "rating" of the program content takes place, to what extent the special program content is of interest to the community members.
- the program content in question can then be integrated into the user-specific programs of at least some of the other users of the user community concerned ,
- the transmission of such an evaluation request signal for a specific program content can also take place after receipt of a survey request signal from a user of the user community, ie. H. a user of a user community can arrange a rating for a certain program content.
- the users can define the exact time intervals for the community-specific program contents of a particular user community within their user-specific programs.
- a seamless integration of the community-specific program contents into the programs of the different users then takes place automatically exactly at the time intervals specified by the users.
- the integration of the community-specific program content in the user-specific programs of the users of a user community is synchronized in such a way that H. coordinated with one another that certain community-specific program contents are arranged in the programs of the individual users with the shortest possible time intervals. This ensures that as many community members as possible consume the program content in question within their program within the shortest possible time frame at the same time or only for a short time, in order to enable a discussion among the community members about the program content in question.
- a preferred broadcasting system has appropriate means for this, for example a suitable user interface for specifying the time intervals by the users and a suitable program scheduler, which ensures optimal integration of community-specific program content into the user-specific programs of the users.
- the user has the option of specifying certain criteria, for example in the user profile, with which priority values are assigned to the various community-specific program contents.
- the priority value of a program content influences, among other things, the priority with which a program content is integrated into the user-specific program, if the period available for the community-specific program contents is very limited, and if so, in which preferred period of all available periods the Program content is accommodated in the user-specific program.
- the establishment of user communities according to the invention within personalized broadcasting systems significantly improves the user experience and the possibilities of the users.
- the compilation of user-specific programs results in an optimal user experience, since the time available for consuming the content is used with maximum efficiency.
- the user communities can be anonymous

- radio systems 1 are radio systems, i. H. are radio systems. It is clear that the invention is not limited to radio systems, but can also be used in the television field or in combined systems.
- the essential part of the compilation of the user-specific programs NSP takes place
- This broadcasting system 1 can therefore be referred to as a server-based system.
- the components shown on the left of the dashed dividing line in FIG. 1 are on the operator's side.
- the components shown on the right side by the dashed line are on the side of the individual user.
- On the operator side in addition to the server 2, there are a number of data sources 6 which deliver various program contents PI to the server 2.
- This can be the operator's own data sources 6, but also third-party data sources to which the server 2 is connected, for example the Internet, third-party radio stations, news agencies, music agencies etc.
- the server 2 has a content profiling unit 8 - preferably in the form of a software module - which first checks the program contents PI arriving from the program content sources 6 and generates content profiles IP of the program contents PI.
- a content profile IP contains e.g. B. the title, a summary, an age rating, ratings etc. of the concerned
- An audio database 5, in which program contents PI are stored, is connected to the server 2 as a further program content source. It is e.g. B. program contents PI, which were sent to the system 1 via the aforementioned program content sources 6 and are buffered in the audio database 5.
- program contents PI which were sent to the system 1 via the aforementioned program content sources 6 and are buffered in the audio database 5.
- the associated content profiles IP previously created by the content profiling unit 8, are also stored in the audio database 5.
- a database 3 is connected to the server 2, in which various user profiles NP for the individual users of the broadcasting system 1 and community profiles GP for the existing user communities are stored.
- the program contents PI which are stored in the audio database 5 or are transmitted at certain times from the further data sources 6, become individual user-specific programs NSP for the individual Users compiled and transmitted by means of a transmission device 11 via individual reception channels Ti to T n to the end devices Ni to N n of the individual users.
- the transmission is coded so that only the corresponding user is able to receive the program broadcast for him via this channel.
- the end devices Ni to N n of the users must be provided with the appropriate keys for decoding the program channels provided for them.
- the transmission channels can, for example, be digital channels within a broadband cable or a satellite-based transmitter system 11.
- the terminals Ni to N n are connected in the exemplary embodiment shown via a retransmission channel R to an interface 12 on the operator side. This can be e.g. B. act over a telephone connection.
- the interface 12 is connected to the server 2.
- System control data such as e.g. B. signals or user profiles etc. are transmitted from the terminals Ni to N n to the server 2 of the broadcasting system 1.
- the server 2 the most diverse facilities are preferably in
- a user community control unit 10 is set up on the server 2, which ensures that after receipt of a corresponding community assignment signal SQ Z of a user, this user is assigned to a specific user community.
- This user community control unit 10 also provides for the creation of the user profiles NP and the community profiles GP.
- a program creation unit 7 which compiles the user-specific programs NSP on the basis of the user profiles NP, the community profile file GP and the content profiles Pp for the individual users and optimizes them in terms of time.
- this program creation unit 7 has a program content selection unit 9, which compares the user profiles NP and the community profiles GP with the content profiles and selects the appropriate program contents PI.
- a time planner 4 is available, which sorts the selected program contents PI in a suitable manner in order to compile the user-specific program, and for a seamless insertion of the community-specific program contents PI G into the user-specific program NSP cares.
- the respective users can, for example, use the retransmission channel R by means of suitable user interfaces on the terminals Ni to N n to specify the exact time intervals in which they would like to receive community-specific program contents PI G of a particular user community.
- Figure 2 shows an alternative concept, which can be referred to as a device-based system.
- a large part of the essential components with which the user-specific program NSP is put together for the user are located within the end device 25 of the user.
- This end device 25 of the user for example a decoder, satellite receiver or the like, has a number of tuner units 20, by means of which program contents PI are received via different channels Ki to K n and are broadcast by a transmission device 33 of the radio system.
- the transmission device 33 receives this
- the terminal 25 has a further interface 30, which serves as a connection for a retransmission channel R, via which the terminal 25 is connected to a central control unit 28, here a server 28, on the operator side.
- a program creation unit 13 which is constructed similarly to the program creation unit 7 in the exemplary embodiment according to FIG. 1.
- the program creation unit 7 in the first exemplary embodiment is more complex, since it has a very large number of user-specific programs in parallel for a wide variety of users of the broadcasting system 1.
- the program creation unit 13 in the terminal 25 only has to compile the user-specific programs for the users of the terminal 25 - in many cases even for a single user.
- the program creation unit which can also be implemented here in the form of software on a suitable processor within the terminal 25, has a content profiling unit 24 and a component Program content selection unit 23 preferably in the form of subroutines.
- the terminal 25 contains a memory 14 in which a user profile NP and the community profiles GP of the user communities to which the user of the terminal 25 is assigned are stored.
- the terminal 25 is used by several users, for example by several
- a user profile NP is stored here, so that a separate user profile NP and the associated community profiles GP are used for each user of the terminal 25.
- a user can also create or have created several user profiles.
- this terminal device 25 Further components of this terminal device 25 are an audio database 15, in which already selected program contents PI can be stored in the form of audio data files, a text-to-speech converter 17 which is able to convert machine-readable data into acoustic information, and a user interface 18 with an automatic speech recognition device 19 and a scheduling device 16, which ultimately sorts the selected program contents in the correct arrangement one after the other and thus compiles a user-specific program NSP that is seamlessly joined together and outputs it to a playback or recording device 26.
- This playback or recording device 26 can be, for example, a radio, a DVD recorder, an amplifier with connected speakers, etc. In principle, this playback or recording device 26 can also be integrated in the terminal 25.
- the user interface 18 is directly connected to the program creation unit 13 and the scheduler 16.
- an output of the text-to-speech converter 17 is connected to the user interface 18 in order to output input requests, information etc. from the terminal 25 or the program creation unit 13 to the user in acoustic form via the user interface 18.
- the scheduler 16 can also directly access the user profiles NP or the community profiles GP in the database 14 in order to
- the user community control unit 29 is located here on the operator side within the server 28.
- community profiles GP can be compiled for the individual user communities. which take into account the interests of the individual users assigned to this user community.
- a community profile GP is compiled from the community-specific profile elements GE of the individual user profiles NPi to NP n .
- the remaining parts of the user profiles NPi to NP n which are not relevant for the respective user community - for example, in the case of a soccer user community, information about marital status, etc. - are preferably not taken into account.
- the community profiles GP are in turn transmitted back to the terminal 25 via the retransmission channel R or via a free channel of the transmission channels Ki to K n and stored in the memory 14.
- a community assignment signal SQ Z which causes the user in question to be assigned to a specific user community, is transmitted from the terminal device 25 to the server 28 or the user community control unit 29 therein.
- Additional program contents for the user can be automatically generated by the terminal 25 via further interfaces 21, 22.
- the other interface 22 from a personal device 31, for example from a laptop, PDA, PC, mobile device, etc. of the user personal data, e.g. B. from a diary, and personal program content can be generated for the user. For example, it is possible to remind the user of dates such as birthdays, deadlines to be met, etc. within the user-specific program NSP.
- FIGS. 4 to 9 show roughly schematic different process sequences.
- Figure 4 shows the establishment of a new user community at the request of a user.
- every user can send a corresponding request to the system or the operator of the broadcasting system that they want to establish a new user community. This is possible by sending a corresponding community constituent signal S NK via the retransmission channel R from the terminal to the server of the broadcasting system.
- the transmission of the community constitution signal S NK is shown here as step 1.1.
- This community constitution signal S NK should contain a proposal for a name of the new user community and the purpose or subject of the user community.
- Step 1.2 then automatically checks the request by the broadcast system provider.
- u. a checked whether the user community is also in the interests of the operator or whether it could be used to pursue unfair intentions, for example, or whether a corresponding one already exists
- a preliminary community profile is first determined in method step 1.3, in particular specifications of the user, who the Community constitution signal S NK (hereinafter referred to as "founder") can be taken over.
- the Community constitution signal S NK hereinafter referred to as "founder" can be taken over.
- An assignment of a user to a closed user community is only possible if the respective user receives an invitation from the user community representative or upon request
- Such closed user communities are mostly personal user communities, in which the community members know each other in real life.
- the property of a user community representative can in principle also be transferred from one user to another of the user community.
- several users of the user community can also be user community representatives.
- process step 1.5 If it is an open user community, other users can join without restriction (process step 1.5). Such open user communities are often anonymous, ie the community members do not know each other in real life. Alternatively, as shown in FIG. 5, user communities can also be automatically re-established by the system. For this purpose, e.g., an automatic process on the part of the broadcasting system operator is running at regular time intervals, which checks all user profiles with regard to common interests that could motivate the creation of a new user group. Each match of interests can be associated with a value number. The individual value numbers are added up to determine the similarities of the user profiles. The system can also create hypotheses for possible community profiles for new user communities and thereby optimize the number of similarity values for a potential new community profile in comparison with all available user profiles.
- Answer signals, ie community assignment signals S G Z are received, the initially created, preliminary community profile GP is updated in method step II.5.
- the user profiles of the individual users are also updated in such a way that membership in the new user community is recorded there.
- FIG. 6 shows the assignment of a user to an already existing user community on the initiative of the user himself.
- the user first of all sends a community assignment signal SQZ to the user community control unit.
- the user community then Control unit checked whether the user is suitable to belong to the specific user community. For example, rules can be stored in the community profile of a user community, which prevent the user from belonging to the user community. An example of this is an age restriction. If the test is negative, the user will be informed.
- the system can automatically send a community entry request S GA to certain users, of whom the system assumes that they are particularly suitable for the user community in question.
- an automatic process e.g. B. in the server 2, 28 on the part of the broadcasting system operator, who analyzes all available user profiles NP for essential correspondences with the community profile GP.
- the same similarity values can be used here, which are also used to find potential users for a new user community. If the similarity exceeds a certain threshold, the user in question will Community entry request signal S GA sent. It is then checked in method step IV.2 whether a corresponding user community assignment signal SQ Z is received by the user in response. If this is the case, the user is assigned to the relevant user community, the corresponding user profile NP and the community profile GP being updated (step IV.3).
- the system can receive information about the user and his preferences by monitoring the user's interactions with the system. Such interactions can be recorded and analyzed by the broadcasting system operator in order to obtain certain user behavior patterns. For example, certain users can always listen to very specific songs of a certain genre or by a certain artist. The system can then be stimulated to either invite the user to join a user community that already exists for this person or the special artist, or even to found a new user community that deals specifically with this music genre or this artist. In this case, the system must have appropriate means with which it can be registered whether the user actually hears the personal, user-specific program content, i. H. whether he switches on his end device or whether, for example, he does not use exactly this program content and has switched off the device or switches over to other reception channels offered in parallel.
- FIG. 8 shows a possible process sequence for how a user can send a program content PIz to other community users.
- program step IV.1 the program content PIz, which the user in question has sent out, is received by the server of the system.
- This program content PIz is then transferred to a central program content selection unit for the other users of the user community or to separate program content selection units for the other users and integrated into the user-specific programs PNS of the individual users.
- a check can first be carried out in method step V.2 by the relevant program content selection unit of the receiving user.
- Such a "filtering" can be used, for example, to check whether the program content PIz is really suitable for the community.
- the integration of the special program content PI Z sent into the user-specific program PNS of the respective user are made dependent on the probability with which the special program content PI Z also fits other parameters within the user profile of the user in question.
- the individual user profiles and also the community profile can contain special "ratio values" which determine what influence an individual user can have, for example, by sending program content on the user-specific program of another user. For example, users who are particularly trustworthy within the User community are known to be significantly more successful in sending PiOgramme content to other users than users who have already received negative feedback about program content that they have sent to other users in the past. Users who know each other can use the user profiles or Community profiles indicate that they want program content that comes from the other user to be integrated into their user-specific program with a particularly high priority.
- step V.1 the user can also send out a simple command so that a program content which has been sent to him by the radio system and which he considers to be particularly suitable for the user community is also sent to the other users of the community. The rest of the process then proceeds as if the user sent his own program content.
- FIG. 9 shows an alternative possibility for users to influence the programs of other users of the same user community.
- the users do not actively send or initiate such a program content to other users of the community.
- the user in question merely initiates a so-called "rating" of a program content PI R by sending out a survey request signal SU A - as soon as the system receives such a survey request signal SU A of a user in method step VI.1, it sends a judgment request signal for the program content PI R in question S B A to the relevant users of the user community who have already received this program content PI R , which causes the relevant users to send evaluation data BD to the broadcasting system 1 returned.
- users can be asked to rate on a scale from 1 to 10 how important the relevant program content PI R is for the user community.
- individual thresholds for the individual users can also be stored in the associated user profiles NP.
- a confidence value can be set for the respective community preference value W GP , which is determined on the basis of the number of participants in the evaluation. I.e. an evaluation in which many users of the user community took part has a higher confidence value, which gives the community preference value W GP more weight. If only a limited time is available within the user-specific program NSP of a community member, a decision as to which community-specific program content PI G is integrated into the user-specific program NPS can also be made dependent on which program content PI G the best evaluation values of the other users of the user community had received. This means that a program content PI G with a good community preference value W GP and a high confidence value has a higher priority than a program content PIQ with a poorer community preference value W GP and / or a lower confidence value.
- the program contents include PI, which are included in the user-specific program NPS of a specific user can, among other things, general program content PI A , which is generally available to every user, user-specific program content PI N , which was only created for the special user, e.g. personal reminders of appointments etc. and community-specific PiOgramme content PI G , which belongs to a special user community, to which the user belongs.
- the community-specific program content PI G can be program content that was explicitly produced for this user community, for example a special feature about a famous rock star for a fan-user community of this rock star.
- Further community-specific program contents PI G can be program contents PIz which have been sent by community members, and program contents PI R which have been subjected to an assessment by various community members and which have received a specific value in this rating.
- a priority value can be assigned to each of these program contents, which depends on how well the respective program content fits the community profile and / or the user profile, which evaluation results the program content received in the event of a rating and / or who sent the program content or initiated the dispatch ,
- Each user can specify the criteria for assigning the priority values, for example, in his user profile.
- For the community-specific program content further criteria can be specified in the relevant community profile.
- Based on the priority value is determined by which Wah ⁇ * probability a program content to certain preferred times in the user-specific program NSP is integrated.
- the various program contents PI are then subjected to a user-specific program optimization in order to create the user-specific program NSP, which is carried out, for example, by the time planner and / or within the program creation unit.
- a user-specific program optimization in order to create the user-specific program NSP, which is carried out, for example, by the time planner and / or within the program creation unit.
- program optimization takes various other parameters into account. For example, every user, the member of one or several user communities can determine within his personal user profile how much time he gives the community-specific program content of a certain user community within his own user-specific program NSP. He can specify exactly when the community-specific program contents PI G are to be arranged within the program. The user can also specify a general relative priority of user-specific program content compared to other types of program content.
- FIG. 10 shows a roughly simplified example of an arrangement of the individual program contents by the user-specific program optimization in a user-specific program NSP, sorted from left to right according to their priority. This sorting does not correspond to the actual chronological order of transmission.
- the program contents PI N specially produced for the user have a higher priority than the community-specific program contents PI G - the general program contents PI receive a priority which is below the community-specific program contents PIQ.
- the program content specially produced for the user community takes precedence.
- the user can change the priorities or the criteria for automatically setting the priority values at any time. In particular, it is also possible to specify different criteria for certain times. Time-critical program content, for example warnings etc. or even time-critical program content within a user community, for example announcements for the user community, are usually given a particularly high priority, even over the program content created for the user.
- the integration of community-specific program content into the user-specific programs is also optimized in this regard. This is particularly true for user communities where the community members also meet in real life. If such program content is available, such as program content created specifically for a main topic of the user community, a period is selected in the user-specific programs of the individual users, so that as many community members as possible can consume this program content at the same time or only at short intervals.
- Transmitting devices can also be divided into several devices networked with one another. Likewise, further process steps such as additional test steps or special optimization processes, further steps for setting priorities, for creating user-specific programs, etc. can be built into the individual process sequences described.
