Patent number: 7177357Abstract: A data processing system and method for stereoscopic 3D video based on MPEG-4. Various elementary streams of left and right images of stereoscopic 3D video are multiplexed into a single stream, and efficient buffer management is performed through field encoding that supports possible display methods. The system minimizes the synchronization time of left and right images and reduces the complexity of the decoder model. Also, a decoding buffer size is allocated to enable support of stereoscopic 3D video field/frame shuttering and stereoscopic 3D video polarized display, while maintaining compatibility with conventional 2D video data processing. Finally, only DTS and CTS are transmitted at the same time, and DTS and CTS of the remaining times are estimated to thereby simplify synchronization.Type: GrantFiled: April 1, 2003Date of Patent: February 13, 2007Assignee: Electronics and Telecommunications Research InstituteInventors: Kugjin Yun, Sukhee Cho, Yunjung Choi, Jinhwan Lee, Youngkwon Hahm, Chieteuk Ahn
