Definitions

  • the invention relates to a convergence box set for personal computers.
  • T-Online Internet service provider authentication
  • Digital signatures the connection of fingerprint recognizers or iris recognizers and the use of the associated software should also be possible on the television.
  • JVM Java virtual machine e.g. for home banking applications and for participating in audio chats (using a microphone)
  • Access (and payment) of the desired content from the Internet Transport either from the Internet via Sterling (authenticity) or download (delayed) or by satellite.
  • the system is intended to enable differentiated and individual media use. Traditionally, this is not possible with push technology such as television, since the user can only see what is currently being offered.
  • time offset recording and later playback
  • the user can also navigate in real time, taking personal preferences into account.
  • the user gives his desired topics, titles, actors once; Directors or keywords and the system uses these specifications to determine an order in which the user changes the programs. He can choose whether to hide unwanted topics or to only place them in a very high program position. Desired topics can be dynamically sorted into low program positions or the television starts automatically when desired.
  • EPG Electronics Program Guide
  • This technology is based on an EPG (Electronics Program Guide), which receives its basic program data from a central station, for example via the Internet.
  • a real-time channel can also be used to transmit program properties that have not been defined in advance and the television can automatically respond to this in its program selection: e.g. Advertising block signals (switching, switching back at the end of the spot, stopping the video recorder);
  • Child protection signals hide violent sex scenes if children are watching.
  • the system is said to include television; VCR; Satellite receiver; Digital receiver; Can control HiFi systems (on; off; channel change; quieter, louder, sound off / on; etc.). Interfaces such as that of an overall harmony should be accessible without the need for new devices with networking interfaces such as FireWire. eg the hi-fi system should be muted when a call is answered.
  • Telephone calls are to be accepted directly on the television using the remote control (display of the caller number, properties / picture of the caller; last call; reason; entering keywords for the current call; saving in a resubmission if callback is desired).
  • All devices connected to the system should be controllable via the Internet, either by calling up direct control commands or by changing control files via Internet dial-up into the system or by changing control files deposited on the Internet and the control instructions the next time the system is dialed onto the Internet accessed and processed. 6. Use of DVDs and Video CD x s and Audio CD's on the television
  • An existing DVD player, CD player, CD burner should be equally usable on the PC or on the TV, regardless of where the user has installed it and without the need for a new purchase.
  • a text viewed on the television should be able to be saved on hard disk or diskette by remote control, or printed out without the need to purchase an additional printer or install it in the living room.
  • the user From the living room, the user should be able to operate the programs familiar in the PC environment and be able to access the data of his PC or the data of his Internet storage area. This PC work should run parallel to TV consumption. Long PC processing jobs should remain observable parallel to the TV program.
  • the switch between TV entertainment or the parallel process on a screen should be supported by window technology. If possible, the TV screen should not only display one program, but several in parallel.
  • the use of familiar 10 instruments (keyboard, mouse) should also be achieved from the living room.
  • the user should be able to use the voice control options that are known on the PC.
  • recognition software can also be used for TV navigation or for navigation on TV.
  • Commercial language software is to be used for this purpose, i.e. without adaptation to the hardware of a set-top box.
  • Texts, e-mails or menu requests should be able to be output on the TV's audio output.
  • Commercial language software is to be used for this purpose, i.e. without adaptation to the hardware of a set-top box.
  • Animations are to be shown within the TV picture, which are either linked to Internet pages or call additional programs.

  • Information tailored to the personal structure should be displayed on the TV screen every morning.
  • the user should be able to print out and archive their personal morning newspaper at the push of a button.
  • In the- Formations are retrieved from the Internet, for example, before getting up.
  • the television should start immediately. Additional state-of-the-art data streams such as teletext or intercast services from the TV stations are to be integrated as data sources, which are also searched for key words.
  • the user should be able to select the program sources regardless of the technical storage locations or delivery routes. He should receive films alternatively from the cable or via satellite via conventional broadcast channels, or he should also be able to play them from the Internet video sequences. The same applies to the integration of DVDs; VCR or video CDs.
  • the set-top boxes must be equipped with modems in order to be able to exchange data with the Internet.
  • Two household connection methods must be technically supported here (ISDN - analogue telephone)
  • a very long telephone cable must be included in the scope of delivery, as there is not always a telephone connection socket near the home television.
  • Sufficient permanent storage must be kept to manage the data (email addresses, Internet bookmarks, telephone and fax numbers, user preferences regarding favorite TV topics and titles).
  • Very large hard disk capacities must be available to save and play back video films. Real-time compression is necessary to make do with less hard disk space. These, in turn, require the most powerful processors and sufficient RAM.
  • Web TV boxes such as the WebTV (R) box from Philips or Sony are known. These types of devices have the disadvantages that not all Internet formats can be displayed in the usual way, since either Java is missing or there is enough buffer space for video and audio streams. Saving Internet pages is also not possible. Also do not print out or only by installing a printer in the living room, which is generally rejected by the user. Digital film storage is no longer required due to the lack of a hard drive, as is local storage. the use of existing email addresses or bookmarks. The export of data obtained while surfing is also difficult because there are no removable media available. There is no interaction with the television program due to the lack of control options. The necessary telephone connection is not available in all living rooms, but often only in the study. The user has to familiarize himself with a completely new navigation. Interactive television is only possible to a limited extent due to a lack of feedback on the program currently being viewed.

  • the software used is compatible with the industry standard, modularly interchangeable and retrofittable.
  • PC data is used seamlessly and is not duplicated to avoid redundancy errors.
  • PC knowledge can still be used and there is no need to familiarize yourself with new navigation systems.
  • TV consumption is supported by a PC, since the PC knows the program currently being consumed at all times and, after a comparison with user preferences and the EPG, offers better programs, hides unwanted scenes or programs, carries out video recording jobs in the background or links the TV broadcast to the Internet or offers interactive services to the user.
