no. 1 example

[0140] The audio playback equipment 15 needs to be configured to be able to manage the fact that it is associated with the decoder equipment 11 via a single communication channel 12 conveying two different audio links 16 and 17 .

[0141] In contrast, users are not surprised by the way sound is rendered.

no. 2 example

[0143] Audio playback equipment 15 need not assume a particular configuration. It is thus possible to implement the invention using any commercially available audio playback equipment.

[0144] In contrast, the user may wonder how the sound is rendered because it is being played by equipment other than the audio playback equipment 15 used to play the multimedia sound.

[0145] Regardless of the contemplated embodiment, sound playback may be associated with visual feedback. Thus, depending on the action requested by the user via the navigation interface 1 , corresponding information will be displayed by the audio / video playback equipment 13 . For example, if the user requests to change the channel, the displayed information may be of the following type: name of the new target channel, programs currently being broadcast on said channel, . . . .

[0146] refer to image 3 , the processor device is thus configured to use the audio / video communication channel 10 to deliver a sin...

Abstract

The invention relates to decoder equipment (11) which includes a first output suitable for connecting to audio playback equipment (15), a second output suitable for connecting to video playback equipment (13), processor means configured to use a first audio link (17) of the first output to deliver a first audio signal coming from an incoming audio / video stream received by the decoder equipment, and to use a second audio link (16) to deliver a second audio signal associated with at least one sound generated by the decoder equipment. The first link presents first characteristics imparting a first latency to the first audio signal and the second link presents second characteristics imparting a second latency, lower than the first latency, to the second audio signal.

Description

technical field [0001] The present invention relates to the field of audio / video playback via one or more pieces of playback equipment. Background technique [0002] Today, in modern home multimedia installations, for the purpose of improving the user's listening experience during playback of audio / video content, set-top box (STB) type decoder equipment is connected both to the audio / video playback equipment and to the It is very common to have one or more pieces of audio playback equipment that are different from the video playback equipment. [0003] Conventionally, decoder equipment attempts to minimize the latency between the moment an incoming audio / video stream is received and the moment video signals from that incoming stream are delivered to the audio / video playback equipment. [0004] In addition, the decoder equipment also attempts to minimize the latency between the moment the user requests an action on the navigation interface, such as going from channel N to ch...
