Abstract

This invention proposes an optimized content based video control method for certain display devices with an effective sensor. We use eyeball sensor as sample, and construct a schema based on eyeball count, “get away” time, video steam frame size with two adaptive threshold(valid “get away”time and the critical frame size threshold ). Generally we need to use this method to decide when to pause the video and whether to roll back the video based on the video steam content.

Content based optimized video display control method

Currently, more and more device manufacturing companies start to provide the intelligent display equipment with certain sensor along with their motion_based video control. Most of the control signals are provided by eyeball tracking sensors or other combination sensors which could provide the same kind of the signals. Normally it works in a simple and straight-forward way. Pause the video automatically whenever the sensor detects a "get away" signal, and resume it automatically when the sensor received a "come back" signal.

However in reality, when we are watching a long video, we can hardly never move our eyeballs, but we don't intend to let the video stop at all. There also can be sometimes we intend to let the video continue to play until there is an attractive scene to watch, or after a long"get away" we want to rollback the video at the good part which we have

just missed. And for most of the times, there will be more than one people watching the video. So in a traditional way, all these circumstances can be managed by using your remoter. But with all the signals which the sensor can detected, we can actually automatically control the video in a delicate way by using our new video_stream recognition based adaptive display controlling schema.

This invention proposes an optimized content based video control method for certain display devices with an effective sensor. We use eyeball sensor as sample, and construct a schema based on eyeball count, "get away" time, video steam frame size with two adaptive threshold(valid "get away"time and the critical frame size threshold ). Generally we need to use this method to decide when to pause the video and whether to roll back the video based on the video steam content, whenever there is only one person, or people number varies.

For the details, eyeball counts will be giving from the sensor, and the "get away" and "come back" time are also what the sensors will detect. The valid "get away" threshold is what would vary for user habits, and also due to the people number change. The video steam frame size is calculated based on the video content, and the critical frame tag will be marked when we get a group of continuous abnormal big size of frames(bigger than the video frame size threshold which is predefined and could adaptively cha...
