Description

System zur freien Auswahl von Diensten zur Personalisierung von FernsehprogrammenSystem for the free choice of services for the personalization of television programs
Die vorliegende Erfindung betrifft ein System zur freien Auswahl von Diensten zur Personalisierung von Fernsehprogrammen nach dem Patentanspruch 1.The present invention relates to a system for the free selection of services for the personalization of television programs according to claim 1.
Das Umfeld, in das die vorliegende Erfindung fällt, ist durch zwei Herausforderungen geprägt. Zum einen stellt das Fernsehprogramm ein Massenmedium dar, d.h. es ist nicht auf die Bedürfnisse des individuellen Konsumenten zugeschnitten, sondern soll in einer einheitlichen Form einer großen Masse an Konsumenten genügen. Zum anderen sehen bekannte Methoden der Personalisierung des Programms, namentlich der persönliche Videorekorder „personal video recorder" (PVR) , eine interaktive Rolle des Konsumenten vor, weil dies eine Aktivität des Konsumenten erforderlich macht, die dieser zuweilen als anstrengend und lästig empfindet. Dieser muss sich, um in den Genuss eines personalisierten Programms zu kommen, z.B. mittels eines „electronic program guide" (EPG), sein persönliches Programm erst zusammenstellen, die Aufzeichnung abwarten und es dann abspielen.The environment in which the present invention falls is characterized by two challenges. First, the television program is a mass medium, i. it is not tailored to the needs of the individual consumer, but should suffice in a uniform form of a large mass of consumers. On the other hand, known methods of personalizing the program, namely the personal video recorder (PVR) personal video recorder, provide an interactive role for the consumer because it requires a consumer activity that he sometimes finds tedious and annoying in order to enjoy a personalized program, for example by means of an "electronic program guide" (EPG), put together his personal program first, wait for the record and then play it.
Neuerungen im Bereich PVR-basierter Dienste versuchen daher, den Genuss eines personalisierten Programms zu erlauben, das als Dienst pro-aktiv für den individuellen Konsumenten zusammengestellt wird, d.h. ohne aufwändige und in der Regel lästige Interaktion des Konsumenten mit der Technik selber.Innovations in the field of PVR-based services, therefore, seek to allow the enjoyment of a personalized program that is compiled as a pro-active service for the individual consumer, i. without complex and usually annoying interaction of the consumer with the technology itself.
Ein Beispiel eines Dienstes zur Personalisierung vonAn example of a personalization service
Fernsehprogrammen ist Zusammenstellen von Programmen, die auf dem PVR aufgezeichnet werden sollen. Beispielsweise können alle Filme eines bestimmten Genres oder eines bestimmten Regisseurs, alle Sportsendungen oder nur alle Fussballspiele eines bestimmten Vereins auf dem PVR aufgezeichnet werden. Ein weiteres Beispiel eines Dienstes zur Personalisierung von Fernsehprogrammen ist das automatische Ausblenden von Werbung während einer Aufzeichnung. Ein weiteres Beispiel ist das Ausblenden von Inhalten, welche nicht für Kinder und Jugendliche geeignet sind.Television programs is a collection of programs to be recorded on the PVR. For example, all movies of a particular genre or director, all sports broadcasts, or just all the football matches of a particular club can be recorded on the PVR. Another example of a service for personalizing television programs is the automatic hiding of advertisements during a recording. Another example is hiding content that is not suitable for children and adolescents.
Um solche Dienste anbieten zu können, werden von Dienstanbietern Metadaten aufbereitet und an die Konsumenten des Dienstes verteilt. Die Metadaten können beispielsweise einen Befehl zum Ausschalten einer Aufzeichnung umfassen, falls ein Werbeblock beginnt. Wenn der Werbeblock beendet ist, kann ein Befehl zum erneuten Einschalten der Aufzeichnung an den PVR gesendet werden.In order to offer such services, metadata is prepared by service providers and distributed to the consumers of the service. For example, the metadata may include an instruction to turn off recording when an ad block starts. When the ad block is completed, a command to re-enable the recording may be sent to the PVR.
Die Dienstanbieter von pro-aktiv personalisiertenThe service providers of pro-active personalized
Fernsehprogrammen stellen den Konsumenten einen auf den Dienstanbieter zugeschnittenen PVR zur Verfügung. Dadurch ist der Konsument an diesen einen Dienstanbieter gebunden und kann nur zu einem anderen Dienstanbieter wechseln indem ein neuer Vertrag mit dem neuen Dienstanbieter abgeschlossen wird, ein von diesem neuen Dienstanbieter stammender PVR erworben und der Vertrag mit dem bestehenden Dienstanbieter je nach Bedingung gekündigt oder unbenutzt gelassen wird. Die hohen Wechselkosten reduzieren in Folge die Attraktivität als weiterer Dienstanbieter in diesen Markt einzusteigen. Ebenso ist es für den Endkonsumenten nicht möglich, die Dienste mehrerer Dienstanbieter gleichzeitig in Anspruch zu nehmen.Television programs provide consumers with a PVR tailored to the service provider. Thereby the consumer is bound to this one service provider and can only switch to another service provider by concluding a new contract with the new service provider, acquiring a PVR originating from this new service provider, and terminating the contract with the existing service provider or leaving it unused becomes. As a result, the high switching costs reduce the attractiveness as another service provider to enter this market. Likewise, it is not possible for the end user to simultaneously use the services of several service providers.
Aufgabe der Erfindung ist es daher ein System anzugeben, welches einem Konsumenten eine freie Auswahl von Diensten zur Personalisierung von Fernsehprogrammen auf einem PVR erlaubt.The object of the invention is therefore to specify a system which allows a consumer a free choice of services for the personalization of television programs on a PVR.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben. Das System zur freien Auswahl von Diensten zur Personalisierung von Fernsehprogrammen umfasst eine Videorecorderfunktionalität, eine Metadaten-Schnittstelle, einen Datenspeicher, einen Prozessor und einen Service- Manager. Die Metadaten-Schnittstelle ist an unterschiedliche Dienstanbieter anbindbar. Durch den Service-Manager sind die Datenspeicherkapazität und/oder die Prozessorkapazität auf Dienste unterschiedlicher Dienstanbieter und/oder auf unterschiedliche Dienstanbieter verteilbar.This object is achieved by the features specified in claim 1. Advantageous embodiments of the invention are specified in further claims. The system for freely selecting television program personalization services includes video recorder functionality, a metadata interface, a data store, a processor, and a service manager. The metadata interface can be connected to different service providers. The service manager distributes the data storage capacity and / or the processor capacity to services of different service providers and / or to different service providers.
Die folgenden vorteilhaften Ausgestaltungen können sich zusätzlich ergeben.The following advantageous embodiments may additionally result.
Durch das gleichzeitige Ausführen von mehreren Diensten können diese unter Umständen gegenseitig in Konflikt geraten. Dies ist z.B. dann der Fall, wenn nicht genügend Datenspeicherkapazität für die parallele Aufzeichnung mehrerer Programme vorhanden ist. Indem die Verteilung der Datenspeicher- und/oder der Prozessorkapazität durch den Benutzer konfigurierbar ist, kann der Benutzer bestimmten Diensten und/oder Dienstanbietern den Vorzug geben, und dadurch den korrekten Ablauf seiner bevorzugten Dienste gewährleisten.Running multiple services concurrently may conflict with each other. This is e.g. then, if there is not enough data storage capacity for parallel recording of multiple programs. By allowing the user to configure the distribution of data storage and / or processor capacity, the user may favor certain services and / or service providers, thereby ensuring the correctness of their preferred services.
Das System kann eine Zertifizierungs-Schnittstelle umfassen, welche mit dem Service-Manager verbunden ist. Über die Zertifizierungs-Schnittstelle ist durch den Service-Manager eine Information empfangbar, welche verwendbar ist, um einen Dienst, welcher über die Metadaten-Schnittstelle empfangbar ist, zuzulassen. Dadurch kann die Sicherheit des Systems erhöht werden.The system may include a certification interface associated with the service manager. Via the certification interface, information can be received by the service manager, which information can be used to allow a service which can be received via the metadata interface. This can increase the security of the system.
Die Fernsehprogramme werden über ein Verteilnetz, in der Praxis oft über ein Kabelnetz, an die Endkunden verteilt. Eine vorteilhafte Ausgestaltung sieht daher vor, für die Verteilung der Metadaten und/oder die Verteilung von Triggersignalen und/oder die Verteilung von Software für das System genau dieses Verteilnetz zu verwenden. Zu diesem Zweck ist die Metadaten Schnittstelle als Schnittstelle eines Verteilnetzes ausgestaltet.Television programs are distributed to end customers via a distribution network, often in practice via a cable network. An advantageous embodiment therefore provides for the distribution of the metadata and / or the distribution of trigger signals and / or the distribution of software for the System to use exactly this distribution network. For this purpose, the metadata interface is designed as an interface of a distribution network.
Für manche Dienste ist es von Vorteil oder notwendig, Daten von dem System an den Dienstanbieter zu übermitteln. Damit der Endkunde hierzu nicht eine separate Schnittstelle zu dem Dienstanbieter einrichten muss, kann vorgesehen sein, dass die Schnittstelle bidirektional ist.For some services it is beneficial or necessary to transfer data from the system to the service provider. So that the end customer does not have to set up a separate interface to the service provider for this purpose, it can be provided that the interface is bidirectional.
Dienste oder nur Teile von Diensten können sowohl beim Konsumenten und/oder beim Dienstanbieter ausgeführt werden. Beide Varianten haben ihre Vor- und Nachteile. Indem zumindest ein Teil der Dienste in dem System ausgeführt wird, kann eine schnelle Verarbeitungszeit einfacher gewährleistet werden. Zudem kann sich der Konsument einer höheren Vertraulichkeit seiner Benutzerdaten sicher sein. Wird hingegen zumindest ein Teil der Dienste bei dem Dienstanbieter ausgeführt, kann das System schlank und technisch einfach gehalten werden.Services or only parts of services may be performed both by the consumer and / or by the service provider. Both variants have their advantages and disadvantages. By performing at least some of the services in the system, fast processing time can be more easily ensured. In addition, the consumer can be sure of a higher confidentiality of his user data. If, on the other hand, at least some of the services are executed by the service provider, the system can be kept lean and technically simple.
Indem eine zur Durchführung eines Dienstes verwendete Software über die Metadaten-Schnittstelle auf das System ladbar ist, können neue Dienste auf das System geladen werden, oder bestehende Dienste durch eine neuere Version aktualisiert werden.By downloading software used to perform a service via the metadata interface to the system, new services can be loaded onto the system, or existing services updated to a newer version.
Mehrere Dienste können auf einfache Weise nebeneinander benutzt werden wenn die Metadatenschnittstelle auf einem Softwaresockel aufsetzt und der Softwaresockel über eine logische Schnittstelle mit einer Middleware verbunden ist. Sowohl einzelne Funktionen, als auch zumindest ein Teil der Hardwareressourcen können dann auf einfache Weise von den Diensten gemeinsam benutzt können.Several services can be easily used side by side if the metadata interface is based on a software socket and the software socket is connected to a middleware via a logical interface. Both individual functions and at least part of the hardware resources can then be easily shared by the services.
Die Metadaten-Schnittstelle kann als physikalische oder als logische Schnittstelle ausgebildet sein. Eine logische Schnittstelle weist jedoch den Vorteil auf, dass das System über bestehende physikalische Anschlüsse an die Dienstanbieter anbindbar ist.The metadata interface can be designed as a physical or as a logical interface. A logical one However, the interface has the advantage that the system can be connected to the service providers via existing physical connections.
