Description

The invention relates to a method for a system for recording and reproducing at least one television signal of a television channel.

From the US 2012/0224835 A1 For example, a device is known that estimates the likelihood of playing back each video record of a group of video recordings that is being rendered on the device during a time interval.

Furthermore, from the US 2016/0088358 A1 a programming recommendation system that narrows the offer of an electronic program guide to a fraction or a short list of about a dozen recommended programs.

The DE 10 2013 222 173 A1 discloses a method for transmitting data for use in a vehicle, wherein - depending on a user request for transmission and reproduction of desired data from a first source via a mobile connection, it is determined whether the desired data is also from a second source free from the mobile connection to be provided.

Further disclosed US 2012/0030721 A1 a method that may include storing a number of programs on a digital video recorder and assigning a rating or ranking to each of the programs.

It is also known that in conventional methods for recording and reproducing a television signal of a television channel, such. B. ARD or ZDF, for a user z. For example, all shipments of the last 24 hours (or longer, eg, 7 days) may be recorded so that they are available to the user at any later time.

The user has the free choice of which recorded programs he wants to view. This process is called Timeshift.

A technically obvious implementation of recording a television signal of a television channel is to store the television signal on a central memory, which can then be accessed by a plurality of users. However, this is not permitted for copyright reasons. Rather, an individual recording of a television signal of a television channel must be made for each user.

Typically, a variety of television signals is recorded for a user, as this - as described - requires an individual copy.

All available television signals that are to be available for Timeshift must be recorded for 24 hours (or 7 days, for example). This involves considerable amounts of data, which must be stored accordingly. Every day fall so z. B. per television signal 24h × 8Mbit / sec data.

Such data volumes per user and per day require large storage media and thus data centers that must be cooled and maintained.

Therefore, it is an object of the present invention to provide a method for a system for recording and reproducing at least one television signal of a television channel, which reduces the amount of data per user when recording a television signal and thus cost, since preferably a plurality of storage media can be saved, and thus Maintenance costs are lower.

This object is achieved by the features of the independent claim. Further advantageous developments are the subject of the dependent claims.

According to the invention, a method for a system for recording and reproducing at least one television signal of a television channel comprises a plurality of steps.

In the present specification, a television signal preferably comprises a plurality of television program contents which are provided at different times. In other words, a television signal has several programs (documentaries, series, etc.) or television program contents which start and end at different times.

Preferably, the at least one television signal has a plurality of television program contents, which are conveniently provided at different times. In other words, from a television channel, such as ZDF, individual television program content or programs are started and stopped at different times.

The recording and reproducing system preferably has a computer-based control center. This helps to control the system.

Furthermore, the system preferably comprises at least one television receiver for receiving the at least one television signal TV channel. Thus, therefore, a television signal of a TV channel can be received.

Furthermore, it is favorable if the system comprises a data memory for storing the at least one received television signal. Thus, the possibility is created to provide a received television signal or one of the television program content contained therein in principle at a later date.

Furthermore, it is favorable if the system comprises a display module for transmitting one or more television program contents of the at least one stored television signal to a terminal of a user and for playback on the user's terminal. Thus, for example, a television program content stored in the data store can be retrieved by a user at any one time.

A terminal is preferably a computer, a tablet, a smartphone, a network-capable TV set and / or a network-capable, in particular internet-capable, device for receiving data from a network.

It is also possible for the control center to be used for transmitting one or more television program contents of the at least one stored television signal to a terminal of a user and for playback on the user's terminal.

The method according to the invention preferably comprises the following steps.

Advantageously, a step comprises receiving the at least one television signal.

Furthermore, a step of the method preferably comprises storing the at least one television signal on the data memory.

Another preferred step of the method comprises detecting at least one television program content selected for playback within the at least one transmitted and stored television signal. Thus, for example, the received television signal can be split into individual television program content. In other words, for example, individual television program contents or broadcasts of the television signal of a public-law television channel or of a television channel can be recognized, as a result of which they can in principle be retrieved individually at a later time.

Further, a step of the method preferably includes creating a user profile based on the at least one captured television program content selected for playback by a user. Creating a user profile has the advantage that conclusions can be drawn from collected data of the past, which characterize the consumption behavior of a user, on its future consumption behavior of television program content.

It is also advantageous if the method comprises, as a step, an evaluation of the created user profile. The evaluating step preferably makes it possible to categorize and catalog the television program contents consumed by a user.

Furthermore, it is advantageous if the method comprises, as a step, calculating the probability with which the user selects a television program content of a stored television signal for playback. By means of calculating the probability, for example, a prediction can be made about the future consumption behavior of a user of television program content.

Preferably, the creation of a user profile comprises the following method steps.

Conveniently, the step of creating comprises classifying the captured television program content that has preferably been selected for playback by a user.

Advantageously, it is classified by retrieving classification information associated with the captured television program content from the Internet or by retrieving classification information associated with the captured television program content.

Advantageously, using an electronic program guide or by reading the stored classification information of all television program content of at least one television signal of a television channel classified.

The classification information preferably includes data on program type, category, actor and / or topic. Thus, a database can be created based on the mentioned categories for recorded television program content.

It is also advantageous if the classification information of a user, in particular in the data memory, are stored. So these are available at a later date and can be further processed.

In summary, when classifying the television program content consumed by a user from the past to the present according to certain criteria, such as genre, actor, etc. are classified or classified in order to make it conveniently comparable to other data or information.

Furthermore, it is favorable if the step of evaluating comprises the following method steps.

Advantageously, the step of evaluating comprises classifying all television program contents of the at least one television signal of a television channel.

Conveniently, it is classified by retrieving classification information from the Internet or by retrieving classification information using an Electronic Program Guide.

Furthermore, it is advantageous if the evaluation comprises storing the classification information of all television program contents of the at least one television signal of a television channel, in particular in the data memory.

Thus, in the step of evaluating, all television program content provided from a television channel for the past to the present is preferably classified or classified according to certain criteria, such as genre, actor, etc., in order to be favorable for it to make other data or information comparable.

It can also be provided that the step of calculating the probability comprises the following method steps.

Advantageously, the step of calculating comprises comparing the classified and captured television program content selected by a user for playback with all classified television program content of the at least one television signal of a television channel.

It is also advantageous if the step of calculating comprises determining the overlaps of the television program content selected, classified and recorded by a user for playback with all classified television program contents.

Simplified, the classified television program content consumed by a user is now compared to all classified television program content to find overlaps.

Furthermore, it is advantageous if the step of calculating comprises determining a probability for a prediction of the next television program content selected by a user for reproduction on the basis of the determined overlaps. Thus, a prediction of the consumption behavior of a user regarding the television program content to be consumed in the past can be made.

Preferably, external parameters, in particular the weather, the season and / or personal data, preferably calendar entries, are also used to determine the probability. In this way, the determination of the probability or its calculation can be specified and adapted to the respective calendar day.

It is also advantageous if the step of calculating comprises dividing the television program content based on the calculated probabilities into at least two categories. For example, subdividing into categories allows the creation of a database which can help the process to provide television program content in e.g. B. interesting and uninteresting for the user quickly subdivided.

Furthermore, it is favorable if television program contents of the first category, which have a higher probability of selection for reproduction by a user, are stored in high quality in the data memory.

Furthermore, it is preferable that television program contents of the second category, which have a lower probability for selection by a user compared to the first category, are stored in the data memory in a low quality compared to the first category.

Preferably, the high quality corresponds to HD resolution, conveniently the low quality corresponds to SD resolution.

In this way, for a user less interesting television program content can be stored in a lower resolution, which in turn leads to increase the available space on a data storage. In other words, the difference between HD resolution and SD resolution per TV program content is gained in storage space.

Furthermore, it is preferred if the data memory for storing the at least one received television signal is designed as a ring memory. In this case, a ring memory or a digital ring memory preferably stores data continuously for a certain period of time and overwrites this again after the expiry of a predetermined time in order to release storage space for new data.

Preferably, the ring buffer comprises a size which allows the television signal to be stored for a predefinable time frame, in particular for 24 hours or for 7 days.

It is also preferred that the method comprises the further method step of deliberately erasing television program content within at least one stored television signal.

Conveniently, the selective deletion includes depending on the user behavior and depending on the provided, predetermined time frame in which a user can jump back within the at least one television signal, the deletion of one or more television program content to save space in the data memory. In this way, the available recording capacity of a data memory or a ring memory can be increased.

Preferably, television program contents are deleted with a calculated probability, which are preferably below a predeterminable threshold value. In other words, television program contents that have already been stored with low quality and / or that are not consumed according to the calculated probability by the respective user, can be deleted if the calculated probability is below a determinable threshold. As a consequence, storage space is created that can be used for television program content that is of interest to the user.

Furthermore, it is favorable when the control center is set up, in each case assigned to a user identification of a respective user, to store at least one television signal of a television channel, in particular digitally. This low, for example, not to infringe copyrights in Germany.

Preferably, the control center is arranged to identify a particular user based on a user identification. Thus, each user can be uniquely identified and provide the television program content intended for him.

Furthermore, it is favorable if the control center is set up to make available to each user the television signals stored for its corresponding user identification.

It is also preferable for the computer-based control center to be connectable to a communication network. Thus, the television program content stored in the data store can be made available via the communications network to other devices, such as user devices, which are also connectable to the communications network.

Preferably, the at least one television receiver is connected to the control center for receiving the at least one television signal of a television channel. In this way, the television signals from TV channels go to the control center and preferably to a terminal or device of a user and preferably in a data memory.

Hereinafter, the inventive idea presented above is expressed in other words.

This idea preferably relates, in simplified form, to a method which preferably records only the broadcasts that the user is likely to actually see and does not store all other broadcasts. This can save considerable storage space.

Expressed again in other words, the method according to the invention advantageously divides broadcasts into categories, e.g. B. A, B, C a.

Conveniently, Category A transmissions are those that the user is likely to view.

Category B transmissions are preferably consumed by a medium probability user, whereas category C transmissions are most likely to be viewed by a user with the least likelihood.

It is advantageous if Category A programs are recorded in the highest quality, Category B programs preferably in low quality and Category C programs preferably in rudimentary quality.

The overall process reduces the amount of disk space required per user.

Conveniently, based on the data on the television behavior of a user, a probability can be calculated how likely it is is that a user retrieves a specific content recorded for him within 24 hours or 7 days.

It preferably includes content-specific features such as actor, category, subject, etc. and user behaviors. These are then conveniently compared with content-specific features of the broadcasts and calculated probabilities with which the respective program will be retrieved by a corresponding user.

The resulting probabilities are preferably associated with external parameters such as weather, season or personal data, such as calendar entries, etc., to improve the quality of the probability calculation.

Conveniently, the categories A, B, and C are then determined on these probabilities and the quality to be stored is selected, so that only transmissions with a minimum probability are recorded.

On the basis of the user's real calls, a control loop is then conveniently created which further increases the quality of the probability calculation and preferably incorporates additional parameters on a trial basis.

For further optimization, it is convenient to analyze the television time of a user, so that each stored content can be provided with a TTL (Time to Live).

This TTL preferably allows content to be stored only as long as there is a significant likelihood that it will be retrieved. For example, if the user no longer uses his television after 2 o'clock in the morning and the content would no longer be available at the next possible television time of the user at 18.00 o'clock of the following day, this content can be deleted at 2 o'clock. As a result, the quality of the method according to the invention can be increased in such a way that a user does not notice that only a very small percentage of the broadcasts are actually recorded or only a very small percentage is stored in the highest quality and so storage space can be saved.

• 1 ein System zum Aufzeichnen und Wiedergeben von mindestens einem Fernsehsignal eines Fernsehkanals.

The invention will be explained in more detail with reference to an embodiment in conjunction with an accompanying drawing. This shows schematically:

• 1 a system for recording and reproducing at least one television signal of a television channel.

1 shows a system 10 for recording and playing back at least one television signal F a TV channel.

The system 10 includes a computer-based control center 1 and a television receiver 2 for receiving a television signal F a TV channel.

The computer-based control center 1 is with a communication network N connected to the Internet.

Furthermore, the control center 1 arranged, in each case assigned to a user identification of a user concerned to digitally store a television signal of a television channel, in particular in a data memory 3 of the system 10 ,

Also is the control center 1 arranged to identify a particular user based on a user identification (a method will be explained in the further description) and each user to provide the television program content stored for its corresponding user identification.

Further, the television receiver 2 with the control center 1 connected to receive the television signal of a TV channel.

Realiter become several television receivers 2 used to record several television signals F different TV channels (eg ARD, ZDF, ...) to receive. However, for the sake of simplicity and clarity, in the present description of the figures, the system will be described 10 or a method based on a television receiver 2 portrayed.

Furthermore, the system includes 10 , as 1 shows and has already been mentioned, a data store 3 for storing the received television signal F and a playback module 4 for transmitting one or more television program contents of the stored television signal F to a terminal 5 a user and for playback on the terminal 5 the user.

The terminal is according to 1 Smartphone, a computer and a network-enabled TV.

Also realiter several playback modules 4 used to broadcast multiple TV program content from different TV channels. However, for the sake of simplicity and clarity, in the present description of the figures, the system will be described 10 or a method based on a playback module 4 portrayed.

The data store 3 for storing the received television signal is formed as a ring memory which comprises a size which is a storage of the television signal for a predetermined time frame, such. For 24 hours or for 7 days.

In the present specification, the television signal F several television program content, which are made available at different times. In other words, the television signal indicates F several broadcasts or television program content that begin and end at different times.

The following is a method of the system for recording and reproducing at least one television signal F a TV channel.

• - Empfangen des Fernsehsignals,
• - Speichern des Fernsehsignals auf dem Datenspeicher 3,
• - Erfassen eines oder mehrerer Fernsehprogramminhalte, die innerhalb des übermittelten und gespeicherten Fernsehsignals von einem Benutzer zur Wiedergabe ausgewählt werden,
• - Erstellen eines Benutzerprofils anhand des erfassten Fernsehprogramminhalts, der von einem Benutzer zur Wiedergabe ausgewählt wurde,
• - Auswerten des erstellten Benutzerprofils, und
• - Berechnen der Wahrscheinlichkeit, mit welcher der Benutzer einen Fernsehprogramminhalt eines gespeicherten Fernsehsignals zur Wiedergabe auswählt.

Here, the method for a system for recording and reproducing a television signal of a television channel briefly comprises the following steps.

• Receiving the television signal,
• - Save the television signal on the data memory 3 .
• Detecting one or more television program contents selected for playback by a user within the transmitted and stored television signal,
• Creating a user profile based on the captured television program content selected by a user for playback,
• - Evaluation of the created user profile, and
• Calculating the probability with which the user selects a television program content of a stored television signal for playback.

The above steps are related below 1 shown in more detail.

While the steps of receiving the TV signal F and storing the television signal on the data memory 3 are self-explanatory, the detection of one or more television program content serves the splitting of the television signal F in individual broadcasts, such as a soap or a documentary, a television signal F form.

After receiving and storing a television signal and detecting individual television program content within the television signal, a user profile is created by means of the following method steps.

In this case, the detected television program content or any recorded program (such as news or a science fiction series) that has been selected by a user for playback is classified.

This is done by retrieving classification information associated with the captured television program content, from the Internet or by retrieving classification information associated with the captured television program content using an Electronic Program Guide (EPG).

Thus, all broadcasts or television program contents of a broadcaster or a television channel selected by a user for playback can thus be classified.

The classification information includes data on program type, category, actor and / or topic. Of course, further classification information is possible, such. Genre, TV channel (ARD, ZDF, ...), etc. There is a multitude of classification information that will not be enumerated for the sake of brevity.

In summary, therefore, a user profile is created for a user by classifying the television program content of a television channel selected by the user for replay or consumed by the user. Thus, in the user profile, each television program content of a transmitter or a television channel for the user is thus included in classified form.

In other words, when classifying a database is created, which in the data memory 3 and in which the television program content consumed by a user has been classified according to various criteria.

In the following step, the created user profile is evaluated.

For this purpose, first all television program content of the television signal of a television channel, in particular by retrieval of classification information from the Internet or by retrieval of classification information using an Electronic Program Guide (EPG) classified.

Thereafter, the classification information of all television program contents of the television signal of a TV channel in the data memory 3 saved.

In summary, when creating a user profile, captured television program content selected by a user for playback as well as all television program content of a television channel from the past to the present are taken into consideration.

Thus, on the one hand, all classified television program contents of the television signal of a television channel (past to present) and, on the other hand, the classified television program contents selected by the user for playback (also past to present) are available.

In the subsequent step, the probability is now calculated with which the user selects a television program content of a stored television signal for playback.

To this end, first the classified and recorded television program contents selected by the user for playback are compared with all classified television program contents of the television signal of a television channel. In other words, the user's few classification information is compared with the total classification information of the television signal of a television channel.

Intersections of the television program content selected, classified and recorded by the user for playback are determined with all classified television program content. Thus, it is thus known which broadcasts or television program content the user has viewed in the past or up to the present and which broadcasts he may wish to watch or consume in the future.

In order to draw conclusions from the past for the future, in a next step, a probability for predicting the next television program content selected by a user for reproduction is determined on the basis of the determined overlaps. So z. For example, the probability of a science-fiction series being sent in the future is high if the user is always consume that series based on past classification data. By contrast, the probability of a soap never being viewed by the user is low.

Furthermore, external parameters, in particular the weather, the season and / or personal data, preferably calendar entries, flow into the determination of the probability. So z. For example, in bad weather and the calendar entry "vacation" to be expected that the user sets for him an above-average television consumption behavior to the day. Therefore, the probability of considering various z. B. science fiction series high, provided in the present example that the user is a fan of this genre. Thus, so the probability of viewing a science fiction series by the user, which is only occasionally or rarely considered by him.

After calculating the probability, the television program content is divided into, for example, two categories based on the calculated probabilities.

Of course, several categories are possible, but in the present example, for the sake of simplicity, only two categories are treated.

In this case, television program contents of the first category, which have a higher probability of being selected for reproduction by the user (ie, for example, science fiction series), are in high quality in the data memory 3 stored.

On the other hand, television program content of the second category, which has a lower probability of being selected by the user than the first category (for example, a daily broadcast soap), becomes low in data memory compared to the first category 3 stored.

Here, the high quality of an HD resolution and the low quality of an SD resolution.

Thus, so the television program content of high interest to the user in a high quality of the system 10 whereas television program content of low interest is of low quality by the system 10 be stored. This can save space in the data store 3 be saved per user, among other things for its television program content with high interest.

For more space in the data store 3 The method step of selectively erasing television program content within the stored television signal may be applied.

Here, depending on the user behavior and depending on the provided, predetermined time frame or storage space in which a user can jump back within the television signal, one or more television program content is deleted to storage space in the data memory 3 save.

That is, television program content is erased with a calculated probability that is below a predeterminable threshold. In other words, a soap which has already been stored with low quality and has never been consumed by the user has e.g. For example, a probability of their viewing by the user of less than 3%.

The threshold of the system, however, is greater than 5%, for example, so that consequently, this soap can be completely deleted to additional storage space in the data memory 3 to generate.

Also, the threshold value can be configured such that in the case of a ring memory of, for example, B. 24 hours and a television viewing behavior of a user between 18 o'clock and 2 o'clock tomorrow, television program content between 2 o'clock in the morning and 18 o'clock are uninteresting, if this - adapted to the present example - z. B. are not science fiction series.

As a result, television program content, apart from science fiction, can be completely and immediately deleted or need by the system 10 not to be stored at all.

As a result, the quality of the method according to the invention can be increased in such a way that a user does not notice that only a very small percentage of the programs or television program content is actually recorded or only a very small percentage is stored in the highest quality and memory space can thus be saved.
