METHOD AND APPARATUS FOR MANAGING BUFFER MEMORY FOR PLAYING VIDEO FROM A PLURALITY OF ACTION CAM

摘要

The present invention relates to a buffer memory management method to play the M number of screens including a first screen and a second screen at the same time through the N number of buffer memories including a first buffer memory to an N^th buffer memory which are buffered sequentially in the video player of multiple action cams. The present invention enables a seamless screen conversion by including the following steps (Wherein M and N are integers greater than 1, N>=M) of: classifying videos of multiple action cams according to the action cams by decoding the videos of the multiple action cams; selecting the N number of videos from the classified videos; storing each of the N number of videos in each of buffer memories; selecting two videos of different action cams among videos stored in the buffer memories; displaying the selected first and second videos respectively in a first screen and a second screen; receiving a selection signal of a third video of an action cam distinguished from videos displayed in the first screen and the second screen; deleting another video which is not the first video and the second video from the buffer memories and storing the third video in the buffer memories where the video is deleted when the third video among the N number of the selected videos is not included; and displaying the third video in the first screen and the first video in the second screen.
