  • the present invention relates to a closed cable network and more particularly the present invention relates to the transfer of multimedia information within such a network and between such a network and one or more on-line services.
  • closed cable networks There are many types of closed cable networks. What is meant by closed cable networks in the context of the present application are networks which are self-contained and the users are easily identified. For example, a multinational or corporate hotel chain provides such a network. In such networks there is typically a facility in each room, office or the like for the presentation of information to a user. Typically this presentation takes the form of multimedia information. Oftentimes, that is information that includes elements of graphics video information that is provided to a customer, employee or the like via a television or like display. A critical characteristic of these types of networks is that there should be a path that provides the owner of the network with knowledge of the activities of a particular user on the network.

  • One problem in this type of system is that these video units cannot be individualized to a particular user because there are simply not enough units. For example, there may be a bank of 64 VCRs which would service a 500 room hotel. Each of the VCRs would have a separate movie. Accordingly, in this case there is a possibility that a particular movie would not be available. In addition, this type of arrangement severely limits the number of choices available.
  • Another problem with the conventional system is that the users do not easily have access to information outside the system. More particularly, as the Internet and other online services become readily utilized it is important to provide the user with easier access to such services. Although these services could be accessed by conventional methods (such as an individual bringing a computer into the hotel room or the like) this is not always possible and oftentimes the particular computer may not be fully equipped to provide such access in an efficient and time critical fashion. In addition, there is a need to provide high speed access to multimedia information from an on-line service to provide quick retrieval and review of such information. A closed cable system provides the opportunity to develop such an environment. Finally such a system allows for the user to be easily identified for marketing and other purposes.

  • the display 1806 can be utilized to interactively operate with the personal computer to cause the printing out of the appropriate transactions via the printer 1804.
  • the printer 1804, typically a laser printer or specialized ticket printing machine prints the information and provides that printed information or ticket to a secure output device 1810.
  • Figure 18B has similar elements to Figure 18a, however the physical system includes a tray for receiving the transactional information. Therefore each customer can have access to an individual tray of information by using their hotel key or the like.
  • the customer has secure access to interactive multimedia transactions.
  • the system can be configured for play along games. Accordingly, an interactive game could be provided which would allow for an individual to play a game such as chess, with another guest in the hotel or against a machine as in the case of a video game or the games could be played with sources outside the network through the on-line service.
  • the IMD 110 itself could be utilized as a call processing system.

Abstract

Cette invention se rapporte à un système qui renforce l'interactivité d'informations multimédia dans un réseau de câbles fermé tel qu'un système de réseau hôtelier ou analogue, lorsque ledit réseau est utilisé en association à un service en ligne. Ce système comporte une pluralité de dispositifs de traitement multimédia, un système de communication multimédia, un système de commande vidéo, une plate-forme d'opérations de servitude et une pluralité de dispositifs interactifs. Ce système présente l'avantage de comporter des algorithmes de compression et/ou de transmission qui maximisent la mise en valeur des informations multimédia. Il assure notamment une interactivité renforcée des informations multimédia par un réseau de câbles fermé tout en permettant un accès amélioré à un ou plusieurs services en ligne avec une modification minimum apportée au réseau existant.
