Frequently, a program can be selected using the EPG to switch to the corresponding program or to program a recording of the selected program.

  • the invention is based on the object to provide a method for completing an electronic program guide for television or radio programs, which allows a complete program overview as possible over longer periods. This object is achieved by the method specified in claim 1.
  • the procedure according to the invention is that data for the electronic program guide, which contains information on individual programs for several programs, in particular the title and the start of the individual programs, are received as additional information in television or radio data signals.
  • One after the other is tuned to receivable programs, whereby it is checked whether program information is present in the additional information of the tuned program.
  • Existing program information is saved, and programs that have no or incomplete program information are highlighted. It then tunes to a program that shares programming information for several programs, checking for a marked program in the program shared program information contained missing data and retrieved data for the marked program are stored.
  • the data for the electronic program guide can be received here in particular as part of a digital television signal.
  • the program information transmitted jointly on a program for a plurality of programs can hereby be received in accordance with a teletext format, in particular according to the NexTView standard.
  • Program overview pages of each teletext received are selected and searched and found program information is stored.
  • Fig. 2 shows the completion of the obtained in Fig. 1
  • a first step 1 the program first tunes to the first program stored in the receiving device and, in step 2, starts the search for the EIT data by means of the predefined and known PIDs.
  • the retrieved EPG data is stored, for example, in a flash memory or on an internal hard disk.
  • step 3 it is then checked whether the EPG data is completely available for the tuned program, wherein the data search is continued until all data is available or a timeout is reached. If the EPG data could not be found or could only be found incompletely, the current program location is highlighted. It is then tuned in step 4 to the next program and the search steps 2 and 3 for the new program will be renewed. If in step 5 a query results that for all Programs the DVB-SI-EIT search has been performed, the first part of the EPG database setup is finished.
  • step 6 the routine for determining program information from NexTView and / or teletext data shown in FIG. 2 is now called to complete the EPG data. However, instead of invoking this routine immediately, it is still possible to first check whether the EPG data is already complete, with only routine access to the routine for incomplete EPG data.
  • step 7 After the start of this update in step 7, it is first checked in step 8 whether a NexTView data emitting transmitter is known and to be received. If so, then in step 9, the program location to which the transmitter is received with NexTView data is tuned. In devices with only one receiving part this is preferably when the receiving device is not used by the user. For example, if the device is in standby mode at night, it can read the NexTView data. For devices with multiple receivers, the process can be done in the background at any time if one of the receivers is not used for re-recording or recording purposes. In step 10, the NexTView data are then read in and stored for the marked program locations with missing EPG data.
  • the NexTView data is transmitted with a cycle time of 20 to 25 minutes, removing data on intermittent programs from the record.
  • the cycle is in turn divided into two data streams, which are transmitted in a multiplex.
  • Data stream 1 contains near time Program information and is shorter, so that it can be repeated several times in the total cycle length.
  • Stream 2 then contains the rest of the program data and is repeated only once every 20 to 25 minutes.
  • query step 11 it is now checked whether the EPG data is complete after the update by the NexTView data. If so, the process ends in step 12.
  • NexTView data is transmitted by several receivable transmitters and there is a different transmitter coverage of the NexTView data, after loading the NexTView data from a first transmitter, it is also possible to first tune to another transmitter with NexTView data, the EPG data to complete.
  • step 13 the tuning data for this program will be loaded in step 13 and the device will be tuned to the appropriate program location in step 14.

Abstract

L'invention concerne un procédé d'établissement d'un guide électronique de programme pour des programmes de télévision ou de radio, des données pour le guide électronique de programme étant reçues sous forme d'informations additionnelles à l'intérieur de signaux de données de télévision ou de radio. Ce procédé consiste à effectuer successivement un réglage pour les programmes pouvant être reçus et à vérifier si les informations additionnelles du programme réglé contiennent des informations de programme. Les informations de programme présentes sont stockées et les programmes pour lesquels il n'existe pas d'informations additionnelles, ou uniquement des informations additionnelles incomplètes, sont marqués. Le procédé selon l'invention consiste ensuite à effectuer un réglage pour un programme sur lequel des informations de programme pour plusieurs programmes sont transmises en commun et à vérifier si les informations de programme transmises en commun contiennent des données manquantes pour un programme marqué, puis à stocker les données trouvées pour le programme marqué.
