Embodiment Construction

[0021] The present invention advantageously provides a method, device and system for providing subtitles for stereoscopic content. Although the invention will be described below primarily in the context of subtitles for three-dimensional content using information files, the specific embodiments of the invention should not be viewed as limiting the scope of the invention. Those skilled in the art will understand and be informed by the teachings of the present invention that the concepts of the present invention can be applied to substantially any stereoscopic image content and subtitle-related received information in other forms than file structures.

[0022] The functions of the various elements shown in the figures can be provided through the use of dedicated hardware and hardware capable of executing software in conjunction with suitable software. When provided by a processor, the functionality may be provided by a single dedicated processor or a single shared processor or m...

Abstract

A method, apparatus and system of the present invention enable the location of subtitles for a stereoscopic image and a selection of the disparity of stereo subtitles to ensure proper display of the subtitles within frames of the stereoscopic content. In one embodiment, the functionality of the concepts of the present invention is based on a player capable of displaying stereo content by reading two streams (one for the left view, one for the right view) and mixing the streams in real time using a mode supported on a 3D display (i.e. line interleaved, checkerboard pattern) based on received file information and inserting the subtitle in the frames by rendering the values in the received file information.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 307,779, filed February 24, 2010. technical field [0003] The present invention relates generally to subtitles, and in particular to a method, device and system for implementing subtitles for 3D content. Background technique [0004] For 2D content, subtitles are usually placed at the same position, eg, below a frame or sequence of frames. In contrast, for 3D content it makes sense to place subtitles in specific areas of a frame or sequence of frames depending on elements in the frame(s). [0005] Another factor to consider with three-dimensional content is the parallax involved with displaying three-dimensional content. More specifically, in the case of two-dimensional content, both eyes receive the same frame, while in the case of three-dimensional content, each eye receives a different frame. Likewise, subtitles of three-dimensional content...
