[0183] Below in conjunction with accompanying drawing, the present invention is described in detail
[0184] 1. Positionable video file format
[0185] The locatable video file format consists of four parts: file header, file index, audio data block, and video data block (such as figure 2 ). The file header describes the overall information of the locatable video file. The file index is optional in the locatable video file. It records the time stamp of each frame of video data and each frame of audio data, the data length, and the position and spatial positioning of the file. The retrieval capability means that the corresponding audio and video content can be quickly retrieved through the latitude and longitude information index of spatial positioning, and the corresponding spatial positioning parameter information can be quickly retrieved through the audio and video index. The audio data block stores the collected and encoded audio data. The video data block stores the p...
