Title
(EN) AUDIO SPLICE PROCESS FOR DIGITAL AD INSERTION
(FR) PROCEDE D'EPISSAGE AUDIO POUR L'INSERTION DE PUBLICITES NUMERIQUES
Abstract
(EN)
A system and method for audio splicing (insertion) of an Ad audio stream in the compressed domain, where variable early delivery of the Ad audio stream and variable bit rate are allowed, without creating audio distortion, glitches, or other digital artefacts or errors, in the resultant audio stream is disclosed. The present system and method provides for a splice delay buffer which delays the first five Ad audio frames until transmission of the last frame of the primary audio stream, but before the splice time. Subsequent Ad audio frames are delayed by a fixed amount, where the fixed amount is greater than the frame delay of the primary audio stream, to allow for ease of splice back to the primary audio stream.
(FR)
L'invention porte sur un système et un procédé d'épissage (insertion) audio d'un flot audio de publicités dans le domaine comprimé, une distribution rapide variable du flot audio de publicités et un débit variable étant autorisés, sans créer de distorsion sonore, de bruits parasites ou d'autres artefacts numériques ou d'erreurs, dans le flot audio obtenu. Ce système et ce procédé fournissent un tampon de retard d'épissage qui retarde les cinq premières trames audio de publicité jusqu'à la transmission de la dernière trame du flot audio primaire, mais avant la durée d'épissage. Les trames audio de publicité ultérieures sont retardées selon une durée prédéterminée, la durée fixée étant supérieure à celle du retard de trame du flot audio primaire, afin de faciliter l'épissage vers le flot audio primaire.
