技術名稱: MVC硬體編碼器矽智財

技術簡介

近年來立體視訊擷取與顯示技術逐日成熟,跟立體視訊編解碼相關的研究也開始熱絡起來,而隨著3D攝影機與3D顯示器的價格逐漸平民化,使得消費性立體視訊的應用日益普及,所以ITU-T也在2010將3D立體高階檔次(Stereo High Profile)增修到H.264 MVC規範中,用以支援普及性較高的雙眼立體視訊應用,例如:藍光光碟的3D影片壓縮即是使用H.264的3D立體高階檔次。 本技術提供高解析度3D立體視訊硬體編碼器IP,符合MVC Stereo High Profile規範,並且向下相容H.264 High Profile標準,可提供國內廠商高品質3D影像服務所需的關鍵技術,並可與現有成果之編解碼IP相互結合,在單一核心即可支援H.264與MVC規格,進而降低成本並帶動3D視訊技術之升級。

Abstract

The Multiview Video Coding (MVC) has been developed as the extension of H.264/AVC by the ITU-T Video Coding Experts and ISO/IEC Moving Picture Experts Group. The Multiview High Profile supports an arbitrary number of views, and the Stereo High Profile is designed specifically for two-view stereoscopic video. MVC provides better compression ratio than simulcast coding because it not only employs motion estimation(ME) to eliminate inter-frame redundancy but also employs disparity estimation (DE) to eliminate inter-view redundancy. With the flexibility of Soft-IP solution, ITRI can provide the industry with a high efficiency MVC H/W Encoder technology for stereoscopic video, and to help our customers develop competitive time-to-market applications for 3D full HDTV applications.
