Method for acquiring addressable stream media based on ASF data amalgamation technology

Abstract

The invention discloses a method for obtaining positional streaming media based on an ASF data confluent technology, which has the steps that audio and video information and spatial orientation information are acquired and then transmitted to a computer on which a Microsoft WME development kit is installed; an ASF streaming media file is used as a container of positional digital video collecting and coding, and a head object of the ASF file is real-timely added with a scripting command object to store the spatial orientation information; the video information and the audio information are compressed and coded in a way of MPGE-4, and then are respectively stored in an ASF data object; by the use of an ASF inside time axis and time domain constraint relationships between the video information, the audio information and the spatial orientation information, reference points on the ASF inside time axis are selected so as to complete the synchronization of the video information, the audio information and the spatial orientation information and realize real-time automatic confluence of the video information, the audio information and the spatial orientation information, and the positional streaming media file is formed. By the method of the invention, the spatial orientation information is added to the ASF container to be recorded and no audio channel is required to be occupied, thusleading the audio information of a positional video to be remained.

Description

Method of Obtaining Positionable Streaming Media Based on ASF Data Fusion Technology technical field The invention relates to a method for integrating video and audio information and spatial information to obtain a positionable streaming media, specifically, a method for obtaining a positionable streaming media based on ASF data fusion technology. Background technique In recent years, multimedia technology has begun to attract the attention of the GIS field. As we all know, the geographic space depicted in the video has a strong sense of reality, can provide easy-to-understand geographic spatial information, and makes people use information more naturally, without complex geometric modeling. It has become a new development in the field of GIS direction. However, the video itself does not have the location and attribute information of the spatial object, so it can usually only be stored and called as a kind of attribute information of the spatial entity, and it is difficul...

Problems solved by technology

The technical problem to be solved by the present invention is that, in order to overcome the shortcomings of the prior art method of adding spatial positioning information to video that cannot be automatically encoded in real time and needs to occupy the audio channel, and considering the popularity of the public, a method based on ASF data fusion technology is proposed to obtain A method for locating streaming media, which automatically integrates video information, audio information and spatial positioning information in real time to form a real locating streaming media file
