| With the development of multimedia technology, audio and video applications are moreand more widely, to occupy an important position in various industries. People tend to choosea database stored information which other than video and audio in the practicalapplication,because multimedia technology is equivalent to a higher threshold of applicationof database technology and higher costs involved (referred to carrying-information),so thatthe audio and video, and carrying-information synchronized between higher costs. Commonmultimedia container tend to focus on the storage of audio and video, people began to try tocarrying-information added to the existing multimedia container, audio and video largeamount of information, if you want other information is added to the audio and video files, itbecomes difficult to locate.Based on the situation, we need to define a new file format-scalable media file format(SMFF) This file format already learn from a variety of multimedia container features, whichmakes audio and video portable information while saved, and thus do not need to care aboutthe information display and audio and video synchronization problem.This article will mainly carry out the following tasks:First, the analysis of the current situation and significance, the analysis of the existingtechnology, and SMFF needs analysis;Second, make the overall design and outline design for SMFF structure;Elaborate SMFF the realization of the principle and to achieve the effect, to explore theSMFF application and outreach programs;The main research-results are as follows:First, combing the the SMFF application requirements, and design needs and defineSMFF format;SMFF the application framework is designed and implemented, the development andapplication of supporting SDK(short of software development kit).With the the SMFF commercial operation works, this format will be more and moremature, really become a new industry recognition multimedia container format. |
