Definitions

  • the invention relates to a decoder device for decoding encrypted programs for TV sets, with an output that can be connected to the input of a TV set.
  • Decoder devices of the type mentioned at the outset are used in the prior art for decoding encrypted (scrambled) television programs for which a subscriber periodically pays a predetermined amount of money to a program provider. The subscription payments are due regardless of whether and to what extent programs of the respective station are consumed. These devices furthermore have the disadvantage that only unidirectional communication between the program provider or transmitter and a program receiver or subscriber is possible.
  • the object of the invention is to provide a decoder device with which an exact assignment of the duration of consumed TV programs and the TV programs themselves to an owner of a decoder device or a subscriber and a bidirectional communication between the owner of a decoder device or subscribers and an external transmitting and receiving device of the program provider or a transmitter transmitting coded programs is made possible.
  • the device contains a receiving device for electromagnetic waves and a transmitting device, via which bidirectional communication with external transmitting and receiving devices is made possible.
  • the decoder device in the decoder device according to the invention, the feature that a receiving device for electromagnetic waves and a transmitting device are provided, by means of which bidirectional communication with external transmitting and receiving devices is made possible, generally flexible design options for billing depending on the program, reception time, Reception time and after Tariff groups for certain groups of people (occupational groups, regions, etc.) is given. According to the invention, only programs that are actually received are billed by a program provider.
  • the device according to the invention also has the advantage that, after installation of the decoder device, a subscriber can receive programs from a decoded program transmitter (pay-TV programs) at any time without further effort and in particular without prior notification.
  • the decoder device according to the invention is easily transportable due to the compact, modular manufacturability of the sub-components that form its combination of features, the decoder device according to the invention is highly mobile, which means that it can also be used in mobile homes and hotels, for example.
  • the transmitting device like the receiving device, emits electromagnetic waves.
  • the wavelength is preferably in the radio waves or decimeter wavelength range. This ensures, on the one hand, ease of manufacture due to the high level of manufacture of such devices, and, on the other hand, universal applicability regardless of geographical conditions.
  • the device is provided with an identification chip with a stored identification number (IMEI number) for the identification of a subscriber. This ensures that an automatic identification of a subscriber via a corresponding identification signal can be transmitted simultaneously or in connection with each signal transmitted by the transmitting device of the device according to the invention.
  • IMEI number stored identification number
  • This enables operation in which the transmitting device of the decoder device according to the invention sends an external receiving device together with an identification signal from the identification chip while receiving predetermined programs, which contains information about the duration of reception, the time of reception of a received program and the identification of the received program.
  • the decoder device preferably has a bidirectional communication interface for a telephone / fax. This makes it possible to send or receive messages to a central transmission device together with an identification signal from the identification chip of the device according to the invention. In this way, spontaneous surveys regarding the Viewers opinion for certain broadcast programs in a simple manner.
  • the decoder device preferably further contains an interface for a personal computer which enables bidirectional communication.
  • the communication options with a central sending station can thus be extended to the services of a personal computer, in particular the sending and receiving of e-mails assigned to a subscriber is made possible.
  • Relay stations are preferably provided to operate the decoder device according to the invention, in order to forward and amplify the signals between the transmitting and receiving devices of the device and an external transmitting and receiving device.
