Function scenario:
1. Play the video file
2. On one, the next song
3. Kara ok function (mediaplayer system simply by switching channels, the resources necessary to mkv file contains three channels (2,1,1) 
That is a particular resource to be useful, although podcasts for me just a monthly summary, but I do not want to mislead people
4. playback mode (sequential, random, loop)
Renderings
Functions are implemented:
1. This is the karaoke function :( mkv file channel switching), the AUDIO accompaniment turn, turn PLAY VIDEO. Of course, the premise is to get mkv file of all channels.
I get all the channels at the time of preparation of the video, and then determine whether or not I should like to have this channel.

});2. Play Mode
Random pattern algorithm: when switching to the random mode, to remove the currently playing out the data, and then when the next song playback, the random from the remaining one, and then removed, randomly. We know that there is no data, no new data again when the total data replication. Note here that, the data collection must be removable clone original set of data, rather than simply copying (note java data storage)
