Audio Video file format and transporing over ethernet

Dear AVBexperts
  I worked on ehternet a bit. But new to AVB and audio and video file 
formats. Where can I find useful information about the video files. How 
audio data embedded??
Can you please let me know the basics of how video file are split into 
avb packets??? If you have any example please share and it will be 
really helpful

Thanks in advance...
