In this paper we describe an innovative synchronization technique based on audio fingerprinting to help create a time base common to source content and receivers. We also introduce, as a relevant use case, the concept of hybrid content radio, a new radio service allowing the enrichment of broadcast radio with personalized audio content. Hybrid content radio is a novel radio service relying on audio replacement, and needing a precise synchronization between the main audio content and the enriching audio. We then discuss a variation of an existing audio fingerprinting algorithm, used to assess the proposed technique using real audio content.

Abstract
In this paper we describe an innovative synchronization technique based on audio fingerprinting to help create a time base common to source content and receivers. We also introduce, as a relevant use case, the concept of hybrid content radio, a new radio service allowing the enrichment of broadcast radio with personalized audio content. Hybrid content radio is a novel radio service relying on audio replacement, and needing a precise synchronization between the main audio content and the enriching audio. We then discuss a variation of an existing audio fingerprinting algorithm, used to assess the proposed technique using real audio content.File | Dimensione | Formato | |
