Our framework is centered on empowering users in telling stories and commenting on personal media artifacts, considering the long-term social context of the user.

We focus on the particular task of supporting socially-aware multimedia authoring, in which the relationships within particular social groups can be exploited to create highly personal media experiences. Our experimental methodology aims at meeting the requirements needed for social communities that are not addressed by traditional authoring and sharing applications. In this thesis we reflect on the traditional multimedia authoring workflow and we argue that a fresh new look is required. The problem is compounded when authors want to integrate community media assets: media fragments donated from a potentially wide and anonymous recording community. These conditions limit the options open to casual authors and to viewers of rich multimedia content in creating and receiving focused, highly personal media presentations. For personal content, nearly none of these conditions exist: content is a collection of assets that are structured only by linear recording time, of mediocre technical quality (on an absolute scale), and with only basic automatic annotations. Content assets are well structured, content fragments are professionally produced with high quality, and production assets are often highly annotated (within the scope of the production model).

For professional content, extensive production support is typically available during creation. This is true for both professional and personal content. Results from our evaluation process indicate that our framework has minimal impact on existing subtitle documents and formats as well as on the playback performance.Ĭreating compelling multimedia productions is a non-trivial problem. This way, we allow the media player to dynamically fix during playback the most common cases of subtitle synchronization misalignment that compromise users' watching experience. The benefit over current approaches lays in the usage of audio fingerprint annotations generated from the base audio signal as second-level synchronization anchors. Building on our previous efforts to address this problem, in this paper we formalize and validate a two-phase subtitle synchronization framework. The truth is that this process often involves a lot of trial- and-error because multiple versions of subtitle documents have distinct synchronization references, given that they are targeted at variations of the same audiovisual content. However, getting the subtitle document that gives satisfactory synchronization on the first attempt is like hitting the jackpot.
