Embodiment Construction

[0019] For purposes of simplicity and description, the present invention has been described with reference mainly to exemplary embodiments of the invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without limitation to these specific details. In other instances, well known methods and structures have been described in detail in order not to unnecessarily obscure the present invention.

[0020] The term "single program transport stream (SPTS)" as used herein refers to a transport stream having a single program. A transport stream is a time sequence of bits carrying audio and / or video information. In order to display content using the STB, audio and / or video information may be decoded.

[0021] The term "multi-program transport stream (MPTS)" as used herein refers to a transport...

Abstract

A 3D video conversion device is operable to convert a first MPEG stream to a second MPEG stream. The 3D video conversion device includes an input module operable to receive a multiple-view stream, a conversion module operable to convert the multiple-view stream. The conversion module includes a decoding module operable to decode the multiple-view stream, a reformatting module operable to generate 3D views from decoded information, and an encoding module operable to re-encode the 3D views to an STB format stream, and an output module operable to output a reformatted stream.

Description

Background technique [0001] There is known to be a growing interest in three-dimensional television (3D TV) and the delivery of multi-view streams to consumers' homes. Stereoscopic TV is a special type of 3D TV in which two views are displayed on the screen, one for the left eye and one for the right eye. Typically, consumers use glasses such that the left eye sees only the left eye view and the right eye only sees the right eye view. [0002] The compression and distribution of these multiple views is known to be done using a number of different criteria. Specifically, the MPEG (Moving Picture Experts Group) standard specifies procedures and bitstream syntax that are often used to decode streams corresponding to multiview. Other specialized methods are known for handling the transmission and display of multiple views. However, the decoders currently in use with many set-top boxes and televisions are known to be unable to decode or display these streams properly. These dec...
