Definitions

  • invention relates to an electronic processing of teletext information such as graphic, alphanumerical data, symbol displayed on television screen and to a transferring method of such information to a printer.
  • Text and graphics added to video signals which are transmitted by TV broadcasters are displayed on the screen in the order of 24 lines 40 characters after being processed through teletext decoders of the television receiver.
  • the object of the present invention is to provide to the user the ability of printing the teletext data such as graphics, alphanumeric data, symbols displayed on the screen and to obtain the print-out of this data in a speedy and errorless fashion.
  • Figure 1 is the diagram of electronic circuit, together with connection points and relevant blocks,
  • the micro controller (4) decodes the demodulated codes coming from infrared receiver eye (7) and to ensure the display of the selected channel on the television tube (13) by means of video processing block (5) of the channel selected, it conveys by two- ways communication method (LTC standard) the pre-calculated channel frequency to programmable tuner (1).
  • LTC standard the pre-calculated channel frequency
  • the signal is amplified by means of intermediate frequency layer (2).
  • the channel selected is the radio frequency incoming from television antenna, from satellite or cable broadcasting. If the video signal contains teletext data, the page number selected by the TV receiver user, is decoded by digital data (teletext) processing block (3).
  • This digital data is formed of 45 bytes packages series for each TV scanning line.
  • a video line containing teletext data is coded in a specific format to enable the decoding operation by digital data processing block (3).
  • the teletext data start with a fixed pattern approximately 12 millisecond after line synchronisation pulse: "10101010101010 11100100". Through the first sixteen byte of this pattern, the receiver obtains the time information. The remaining part helps to identify the position of the character. Then, magazine and package address group (MPAG) of two bytes and subsequent to this, data of 40 bytes arrive. (Figure 2.).
  • MPAG magazine and package address group
  • Digital data of the teletext page is transferred from memory (8) to buffer (9), which operates as a memory storing information for a limited time period, and then to micro-controller in interface block (10).
  • Matrix and characters in graphic form incoming as digital information are converted at this interface block (10) to printer format PCL and forwarded to printer (2) by means of the connector (11) output.
  • the standard printer (12) connected to the said connector (11) the print-out of 24 lines of the page kept in the memory (8) is taken on a paper.
  • the signal containing teletext information is coded and processed entirely by digital ways. As the environment up to printer is entirely digital, there is no need to use an additional analog/digital converter circuit.

Abstract

Conformément au procédé de la présente invention, une ligne vidéo contenant des informations télétexte fait l'objet d'une reconnaissance et d'un décodage par un bloc de traitement de données numériques (3) et lesdites informations sont transférées d'un microcontrôleur (4) vers un bloc interface (10) en passant tout d'abord par une mémoire (8), puis par un tampon (9). Dans ledit bloc interface (10), la matrice graphique et les caractères qui arrivent sous forme de données numériques sont convertis en format PCL et transférés vers une imprimante (12) au moyen d'un connecteur (11), ce qui permet de transférer sur un autre support des informations disponibles sur un écran de télévision.
