Definitions

  • the present invention relates to methods for generating and providing or transmitting a playback index for a multimedia signal, which contains a detectable start signal and / or a time code and to which a program identifier is assigned.
  • the invention further relates to methods for playing back such a multimedia signal, which is recorded on a medium with temporally random access with respect to a start signal and / or a time code and to which a program identifier is assigned.
  • multimedia signal is used as a generic term for all types and combinations of audio, video and other data streams which are perceptible in particular by the senses.
  • Multimedia signals for example television programs, often contain sections which are of little interest to the consumer or are even interpreted as a disruption or interruption, for example advertising. While viewing or waiting for these sections while the multimedia signal is being broadcast is inevitable for the consumer, it is possible for a multimedia signal recorded on a medium, for example a video cassette, to skip or "fast forward" these sections. With tape drives, such as conventional video cassette recorders, this is a time consuming process. It is tedious to find the end of the section to be skipped to find the correct re-entry point for playing.
  • a system known as the "video programming system” (VPS) has been established for pinpointing the beginning of a video broadcast of interest.
  • VPS signal contains a code which is assigned to the respective program.
  • the time is used as the code, which corresponds to the approximate start time of the shipment.
  • the VPS system does not make it possible to skip unwanted sections within a recorded program, such as advertising, interim reports or moderations.
  • Other systems have therefore been designed which are based on the practice of television stations to hide the station logo which is usually shown in a corner of the television picture during the duration of an advertisement.
  • image processing algorithms With the aid of image processing algorithms, it is possible to monitor the video signal for an element that is constant over a long period of time and to use the absence of such an element as a identifier for a video signal section to be skipped.
  • the known systems can only provide a rough indication of a section to be skipped.
  • EPG electronic programming guide
  • multimedia signals with a time code so that sections of the multimedia signal are exactly, e.g. in the case of a video signal can be controlled precisely or half-frame.
  • the time code is continuously integrated in the multimedia signal, e.g. in its own frequency range, its own data channel or e.g. in the case of packet streams, such as the Internet protocol, packed in the headers of the individual data packets. Even timecode does not allow unwanted sections in the multimedia signal to be skipped.
  • the invention is based on a new type of recording media available on the market, which allow a random access to a recorded multimedia signal: magnetic disk storage, semiconductor storage, optical storage, DVDs, etc.
  • the system according to the invention is composed of two components, namely first process components that are carried out on the part of an Internet service provider, and second process components, which are rarely carried out by a consumer.
  • a first method according to the invention of the first components is a novel method for providing a publicly usable playback index for a multimedia signal, which contains a detectable start signal and to which a program identifier is assigned, and which comprises: detecting the time of the start signal, Playing at least a section of the multimedia signal on a multimedia workstation, the playing time being measured with respect to the time of the start signal,
  • a first method of the second components of the invention is a novel method for playing a multimedia signal, which is recorded on a medium with random access with respect to a start signal and to which a program identifier is assigned, and which comprises:
  • the play index being related to the time of the detected start signal.
  • a system for the indexed playback of a recorded multimedia signal is created, which is based on a novel combination of three elements: the exact time specified by a start signal system such as the VPS system, the free addressability of a multimedia signal medium with random access and the unlimited distribution possibility of the Internet.
  • the system is based on the concept of starting parallel, but self-sufficient counters or clocks on the part of the Internet service provider who creates the index and feeds it into the Internet and on the part of the consumer recording the multimedia signal, so that the index created by the Internet service provider is precisely timed matches the multimedia signal recorded by the consumer.
  • the system of the invention enables uninterrupted, precisely cut and adaptable playback presentations of multimedia signal recordings.
  • the system takes into account the narrowband nature of today's Internet connections by only getting the playback index via the Internet, whereas the multimedia signal is distributed via conventional broadband connections, such as terrestrial radio, satellite radio or cable television.
  • a preferred embodiment of the Internet service provider-compatible method component of the invention which is intended for multimedia signals that contain a detectable scene identifier (for example a faded-in transmitter logo), is characterized in that those sections are played that occur in time with the detected input or Switch off a predefined scene identifier. In this way, the selection of a scene at the multimedia workstation is made easier since it is no longer necessary to analyze the entire multimedia signal, but rather only certain sections of the same.
  • a detectable scene identifier for example a faded-in transmitter logo
  • the method is further simplified if, according to a further feature of the invention, it is provided that the point in time at which a predetermined scene identifier is switched on or off is detected and, together with a classification of this scene identifier, is stored as a provisional entry indicating that that section is being played , which is in a temporal environment at this time, and that the addition is made on the basis of the provisional entry.
  • a faded-in transmitter logo is preferably used as the scene identifier.
  • any other detectable scene identifier could be used, for example previously known subtitles that are shown, special teletext information that is transmitted in the blanking interval and that is characteristic of a scene that is currently being broadcast, or the repetition of a scene itself, such as, for example, after the end of one There is a commercial break where the film continues a few seconds before the time of the interruption.
  • the term “scene” denotes a time-limited subsection in a time section of the multimedia signal that can be classified automatically or manually.
  • access to the Internet server is billed. Any billing or payment method known in the art can be used for the charge, for example billing via an Internet access provider, the telephone bill, the cable television bill, the electricity bill, credit cards, bank accounts, vouchers, cybercash, tokens, etc.
  • a preferred embodiment of both process components according to the invention is that the start signal is a VPS signal.
  • the VPS system introduced can be used to establish the time synchronization between the recording of the consumer on the one hand and the reception or recording of the Internet service provider on the other.
  • the invention also takes into account other types of start signals in the broadest sense, for example the interaction of time synchronization and television program transmission in the context of the EPG system, which can be used as a start signal as explained above, or a time code contained in the multimedia signal.
  • the play index need not necessarily be provided on an internet server and over the internet; alternatively, it is possible to provide any randomly accessible database that can be accessed from the location of the consumer via any data connection. Such preferred variants of the method according to the invention are particularly claimed in claims 9 and 14.
  • the play index can be obtained not only by server-side provision and client-side access (“PULL” technology), but also by server-side transmission and client-side reception (“PUSH” technology).
  • the broadcaster can also send a whole group of play indexes, for example by means of email, internet channels, terrestrial Radio, cable television, satellite radio, etc., eg repeated periodically.
  • the correct play index on the recipient side is selected from the received group of play indices on the basis of the program identifier.
  • Such preferred variants of the invention are particularly claimed in claims 10 and 15.
  • the multimedia signal is preferably an analog television signal, with the start signal being transmitted in the blanking interval.
  • the multimedia signal can also be a digital television signal that is provided with a time code.
  • a preferred variant of the invention is that the multimedia signal is distributed over at least two channels, the start signal or the time code being transmitted on a separate channel.
  • a start signal or such a time code can be formed, for example, by the EPG signal of the EPG system transmitted in a separate data channel.
  • the group of play indices can preferably be transmitted on the same channel as the start signal or the time code become.
  • time can be understood both continuously and discretely in the present description.
  • a preferred form of discretization or quantization of the time consists in that the times, the playback time and the playback index are measured in single or field images of the multimedia signal. In this way, the playback can be indexed precisely.
