[WM]: Watermarking attacking

["=?GB2312?B?wda93Mny?=" <shenlj636@gmail.com>]

Hello,everyone!

I am working at video watermarking,and puzzled about the watermarking attacking(e.g.delete frame).

If you work at it,could you kindly help me solve the following problems:

1.How is the temporal desynchronization attacking(e.g.delete frame) commonly operated in the video streams or in the image sequences
after decoding the compressed video streams?

2. If it is operated in the compressed streams,whether the "I" frame could be deleted or not?

If you are kindly to help me,could you please explain your answer in details? I am eagerly to know the reasons.

Deeply appreciate for your attention. Thank you very much!
