Audio signals associated with the "next" audio source are then transmitted to audio output device 134 for output to the user (step 208).
  • audio signals associated with a "next" audio source are communicated to audio output device 134 to be output to the user.
  • the present invention allows the user to cycle through all the available audio sources by repeatedly clicking on audio source button 152.
  • the present invention may allow the user to specifically select an audio source whose audio signals are to be output to the user via audio output device 134.
  • Fig. 7 depicts a simplified flowchart 220 showing processing performed by set-top box 130 according to this embodiment of the present invention.
  • set-top box 130 upon receiving the audio source button signal, set-top box 130 determines all the audio sources embedded in the Web content and/or the television content received from distribution center 106 (step 220).
  • Set-top box 130 then generates a user interface which displays the available audio sources to the user (step 222).
  • the user interface is generally presented to the user via display device 136.
  • Various types of user interfaces may be provided allowing the user to select a particular audio source.
  • the user may then use the various buttons located on remote control device 138 to select a particular audio source whose signals are to be output via audio output device 134 (step 224).
  • set-top box 130 Upon receiving the user's selection, set-top box 130 then transmits audio signals associated with the user-selected audio source to audio output device 134 for output to the user (step 226).
  • the user may specifically indicate an audio source whose signals are to be output.
  • the present invention allows the user to control the audio signals which are output to the user via audio output device 134. It should be apparent that various other techniques, in addition to those described in Figs. 6 and 7, may be used by the present invention to determine an audio source to be played back to the user.

Abstract

Cette invention concerne un système permettant de visionner une information à contenu Internet et une information à contenu télévision, ces deux informations pouvant renfermer une pluralité de sources audio. A la réception d'un signal (192) en provenance d'un dispositif de commande, tel qu'une télécommande pour téléviseur, le système selon l'invention sélectionne une source audio parmi la pluralité de sources audio (194) et transmet les signaux audio associés à la source audio retenue à un dispositif de sortie audio (196).
