  • EPG electronic program guide
  • STBs set top boxes
  • Conventional EPGs display schedule information for television programs in a grid-based format.
  • One axis of the EPG typically corresponds to channels or stations, while the other axis corresponds to time slots. Rectangular elements formed within the grid represent specific television programs.
  • EPGs have numerous advantages over conventional printed guides (such as TV Guide ® ), EPGs are still based on the channel/time slot model, which is of diminishing importance today. For example, where a viewer has access to over 500 channels, he or she is not interested in the fact that the latest episode of Friends ® is being shown on Channel 498. Rather, the viewer would simply like to know when the program is being broadcast and allow the entertainment system to automatically switch to the appropriate channel.

Certain attributes 506 may contain meta-data related to the PIO 502, the represented television program, or both. For example, one attribute 506 may indicate the size of the PIO 502. Another attribute 506 may indicate the video encoding format of the represented television program. As described more fully hereafter, attributes 506 may be used to sort, filter, search, prioritize, or otherwise organize a set of PIOs 502. Moreover, certain attributes 506 may be used in the context of certain actions 504. For example, an action 504 for recording a television program may need to access the attributes 506 containing the channel, starting time, and running time of the television program.
  • Each of the attributes 506 in a PIO 502 may include a triplet of information, e.g., the attribute name (Program Title, Program Broadcast Time, Program Broadcast Channel), the attribute's type (searchable text, time, executable code, GIF image, ATVEF triggers and their time mark within the program, MIME, or the like), and the attribute's value.
  • attributes 506 may include text in multiple languages to allow the PIO 502 to be used in different countries around the world.

Abstract

L'invention concerne des programmes télévisés représentés par des objets d'interface de programme (PIO) (502), à l'intérieur d'un système de télévision interactive (100). Ces PIO constituent un indicateur visuel (508) permettant d'identifier rapidement le programme télévisé représenté, des attributs (506) fournissant des informations sur le programme représenté, ainsi que les actions (504) pouvant être réalisées sur ledit programme télévisé représenté, ou en lien avec celui-ci. Les PIO (502) peuvent être triés, filtrés et/ou gérés en fonction des critères établis par l'utilisateur. Ces PIO peuvent être transmis entre divers dispositifs électroniques et applications logicielles.
