NTT Research and Development 2012 Review of Activities

Overview

Our codec engine is an encoder engine and a decoder engine for H.264 video. The engines are implemented as modules in the Direct Show Filter^*1 and Shared Library^*2 formats, so they can be combined with audio codec engines to develop videoconferencing software such as client software for personal computers or MCU^*3 software for servers. The light processing and low delay enable natural and high sense-of-presence videoconferencing with HD video on popularly-priced personal computer that rivals the user experience of expensive hardware terminals.

Features

• A variety of videoconferencing software for Windows and Linux can be developed.
• Conforms to the H.264 Baseline^*4 /Main/High Profile
• Can encode full-HD video at 2 to 3 Mbit/s
• Light processing and low delay enable videoconferencing with HD video on popularlypriced personal computers.
• Compatible with the widely-used H.323 and the JJ-40.30 for the NGN

Application scenarios

• High sense-of-presence videoconferencing HD video can be experienced at low cost using a personal computer.
• Guaranteed-bandwidth videoconferencing over NGN using JJ-40.30
• Multi-point videoconferencing implemented with MCU servers running on Linux

• *1 Direct Show Filter: Windows software module format
• *2 Shared Library: Linux software module format
• *3 MCU: Multipoint Control Unit
• *4 H.264 Baseline error resilience tools not supported
