Non-linear interactive access to video is very important in video information management. The term non-linear refers to that there are more than one video streams delivering to users. To access video in a non-linear interactive way, it will involve issues such as: hyper-link to the external text source, synchronization between audio and video, hyper-link to external video, parameter passing, buffers for multiple streams of video, segmentation of video objects, representation of video sequences and the organization of source data. It is significant to study these issues clearly and develop a video annotation mark-up language (VAML). This paper introduces the main idea of VAML.
