摘要
DSM-CC(数字存储媒体指挥与控制)数据传送带可以通过循环重传提高可靠性、可用性和兼容性。在MPEG (Moving Picture Experts Group)-4系统中,通过基于对象的编码可以对每个对象进行独立管理。该对象由ES (Elementary Stream)组成,并通过DMIF (Delivery Multimedia Integration Framework)层传输。通过卫星(CMS)实现的DSM-CC-Data Carousel与MPEG-4系统的合作系统是使用现有的MPEG-4系统和DSM-CC-Data Carousel。每个系统可以使用DMIF描述符一起工作,流通过卫星传输。CMS采用DMIF、MPEG-4 ES (Elementary stream)和DSM-CC data Carousel等技术在运行时改变数据流的内容,并通过循环重传提高可靠性、可用性和兼容性。介绍了基于卫星的DSM-CC-Data Carousel与MPEG-4系统的协作系统。
Cooperation system of DSM-CC Data Carousel and MPEG-4 system via satellite
The DSM-CC (Digital Storage Media Command and Control) Data Carousel can improve reliability, usability and compatibility by cyclic retransmission. In MPEG (Moving Picture Experts Group)-4 system, each object can be managed independently by object-based coding. The object is composed of an ES (Elementary Stream) and transmitted through the DMIF (Delivery Multimedia Integration Framework) layer. The cooperation system of DSM-CC-Data Carousel and MPEG-4 system via satellite (CMS) is using the current MPEG-4 system and DSM-CC-Data Carousel. Each of the systems can work together using the DMIF Descriptor and streams are transmitted via satellite. The CMS can change the contents of the data stream in run-time using DMIF, MPEG-4 ES (Elementary Stream) and DSM-CC Data Carousel and improve reliability, usability and compatibility by cyclic retransmission. This paper describes the cooperation system of DSM-CC-Data Carousel and MPEG-4 system via satellite.
