Abstract

Today, most of the multimedia devices and cell phones feature an audio/video player. These devices run on a very limited supply of battery. The disclosure described is a mechanism by which, a multimedia device, when near its discharge (10-15% remaining), can increase the playback frame rate of the video, so that the user can use the same amount of battery power, to see more of the multimedia content than he would normally have.

A novel method to automatically set the playback frame rate of a multimedia video based on the current battery charge level

Today, most of the multimedia devices and cell phones feature an audio/video player. These devices run on a very limited supply of battery. The disclosure described is a mechanism by which, a multimedia device, when near its discharge (10-15% remaining), can increase the playback frame rate of the video, so that the user can use the same amount of battery power, to see more of the multimedia content than he would normally have.

Currently there are no such solutions to this problem. There are some media players available on the web, which allow the user to change the frame rate of the video. However, they do not change the playback frame rate automatically based on the battery condition. User has to manually change it and remember to revert it when required. Also, most of the users do not even realize that this feature can be leveraged to see more of the video content in the same time. Thus, if this playback frame rate change is automated, the user will not have to care about changing any settings by himself/herself.

Following problems exist in current solutions.
1) User has to manually change the frame rate.
2) User needs to go through entire video / scan through video manually.

There is a need to provide a mechanism that can allow user to associate battery level with the video run time so that user can watch the video before battery dies down.

Article proposes to provide a mechanism to associate video run time with battery level in the mobile device (Notebook, mobile phones etc...).

A normal video (any kind of video, vcd, DVD, avi, divx, and mp4) has a frame rate of 24-30 fps. If while watching the multimedia video content, the user plays back the video at a slightly higher frame rate, say user increases by 2 fps, the user would not know the difference (very minimal and tolerable difference). But this marginal increase of frame rate would allow the video to finish sooner that it would have normally. Just to give an example, a 2 hour video will be over in 1 hour 50 minutes. This gives us a 10 minute reduction in playback time. Idea proposed in article will achieve following objective:
