Abstract
Systems, apparatus and methods are provided for the real-time positional manipulation of stereoscopic (3D) subtitles in a stereoscopic viewing environment. A stereoscopic subtitling workstation is provided for creating stereoscopic subtitling content for use with stereoscopic video content in which stereoscopic subtitling content can be manipulated and adjusted in real-time in a stereoscopic viewing environment to set the desired viewing position and appearance parameters for the stereoscopic subtitling content. The stereoscopic subtitling workstation may further automatically analyze the stereoscopic video content and automatically generate optimal viewing parameters for the stereoscopic subtitling content, including its 3D offset, according to desired appearances and interaction between such content. The automatically generated stereoscopic subtitling content parameters could then use the real-time manipulation features of the workstation to further fine tune the automatically generated stereoscopic subtitling content parameters.
