Is there a pattern in streaming video data? I was thinking something along the data in the "magic (5)" file that is automagically used by "file (1)" command. (What a convoluted sentence!) Or something like uuencoded-type pattern?
I am writing a fiction in which the main character was looking at a stream of data. He then recognized that the data is some kind of video stream. Now, what kind of pattern did he see? Is this realistic? He might be looking in the middle of the stream, though. So if the pattern is at the begining of the file, then he might miss it.
