Problems solved by technology

[0008] However, the existing MPEG-4 system only standardizes two-dimensional (hereinafter referred to as "2D") multimedia data, and therefore rarely involves techniques for processing stereoscopic / multi-view 3D video data.

Embodiment Construction

[0045] In the following detailed description, only the preferred embodiment of the invention has been shown and described, simply by illustration of the best mode contemplated by the inventors for carrying out the invention. As will be realized, the invention is capable of modification in various obvious respects, all without departing from the invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

[0046] In an embodiment of the invention, MPEG-4 stereo / multi-view 3D video data is processed. Specifically, according to the user's system environment and the display mode selected by the user, the encoded, field-based elementary streams output at the same time through multiple channels are integrated into a single-channel elementary stream, and then multiplexed into a single 3D Access unit stream (hereinafter referred to as 3D_AU stream).

[0047] More specifically, streaming can support all four display modes: 2...

Abstract

Disclosed is a stereoscopic / multiview three-dimensional video processing system and its method. In the present invention, stereoscopic / multiview three-dimensional video data having a plurality of images at the same time are coded into a plurality of elementary streams. The plural elementary streams output at the same time are multiplexed according to the user's selected display mode to generate a single elementary stream. After packetization of the single elementary stream continuously generated, information about the stereoscopic / multiview three-dimensional video multiplexing method and the selected display mode information are added to the packet header of the stream. Then the packetized elementary stream is sent to the image reproducer or stored in storage media. The present invention multiplexes the multi-channel elementary streams having the same temporal and spatial information, thereby minimizing the overlapping header information, and performs streaming of data suitable for the user's demand and the user system environments.

Description

technical field [0001] The present invention relates to a three-dimensional (3D) video processing system and method thereof. More specifically, the present invention relates to a device and method for processing stereoscopic / multi-view 3D video images based on MPEG-4 (Moving Picture Experts Group-4). Background technique [0002] MPEG is an information transfer method represented by video image compression and encoding, and is developed to next-generation compression method MPEG-7 following current MPEG-1 / 2 / 4. [0003] MPEG-4, a video streaming standard for freely storing multimedia data including video images in digital storage media on the Internet, is now commonly used, and MPEG-4 can be applied to Portable World Wide Web Broadcasting MPEG-4 Players (PWMP) Wait. [0004] More specifically, MPEG-4 is a general-purpose multimedia standard that increases the compression coding of existing video and audio signals, including still images, computer graphics (CG), Composite a...
