Protocol to Support Real-Time Video Teleconferencing on Integrated Services Digital Network

本项目由美国国家科学基金会（NSF）小企业创新研究（SBIR）项目资助，该项目旨在为小企业，特别是小型高科技公司提供参与NSF研究的机会。SBIR项目的第一阶段是筛选有前途的提案，并确定公司是否可以进行高质量的研究。第二阶段为主要研究项目。第三阶段是将nsf资助的研究转化为商业应用和技术创新，由后续的私人风险资本或其他非联邦融资支持。这是一期工程。PI正在为ISDN开发一个视频协议，为在不久的将来可能由ISDN和图像压缩技术派生的所有实时视频电话会议实现提供基础。该协议面向个人电脑，将其转换为视频电话。个人电脑的开放架构很可能成为个人视频电话的选择平台，这应该是一个繁荣的市场，将导致公众最终接受ISDN标准。该协议的主要目标是为基本接入ISDN上的个人视频电话会议和主要接入ISDN上具有更大、更高分辨率图像的企业视频电话会议提供支持。因此，一种协议可以在各种ISDN配置中支持视频电话会议。

This project is funded under the National Science Foundation's (NSF) Small Business Innovation Research (SBIR) program, which is designed to provide an opportunity for small business, particularly the small high technology firm, to participate in NSF research. Phase I of the SBIR program serves as a filter to select promising proposals and determine if the firm can do high quality research. Phase II is the principal research project. Phase III is the conversion of the NSF-funded research into commercial applications and technological innovation supported by follow-on private venture capital or other non-federal financing. This is a Phase I project. The PI is developing a video protocol for ISDN, to provide the foundation for all the real-time video teleconferencing implementations likely to derive from the ISDN and image compression technologies in the near future. The protocol is directed toward personal computers, converting them to video telephones for the application. The open architecture of personal computers will most likely be the platform of choice for personal video telephones, which should be the boom market that will cause the general public to finally embrace the ISDN standard. The principal objective of this protocol is to provide support for personal video teleconferencing over basic access ISDN, and corporate video teleconferencing, with larger and higher resolution images, over primary access ISDN. Thus, one protocol could support video teleconferencing in a variety of ISDN configurations.
