First, Riff ('av '...) Represents the AVI file type. The first list required by the AVI file is the 'hdrl' list, which describes the format information of each stream in the AVI file (each media data in the AVI file is called a stream ). The 'hdrl' list contains a series of blocks and sublists. The first is an 'avih 'block, whi
when I first entered the FCC. Because it is not a data type at first, it is not a circular selection statement, not an operator. It starts with the HTML. I can only say that I have wasted too much time on repeating things.

, which describes the format information of each stream in the AVI file (each media data in the AVI file is called a stream ). The 'hdrl' list contains a series of blocks and sublists. The first is an 'avih 'block, which is used to record the global information of an AVI file, such as the number of streams, width and height of the video image, you can use an AVIMAINHEADER data structure to operate:

Here's a quick review of the issue:
What is net neutrality all about?
The principle generally means that content isn' t prioritized above others, so that a user can go where he wants and do what he wants on the Internet without the interference of his broadband provider. supporters of net neutrality protections say that without the rules, Internet service providers like Comcast and Time Warner will have economy mic incentives to charge conte
, the Federal Communications Commission (FCC) announced the distribution of three 100MHz bands in the 5GHz band, used as a u-nii (national information infrastructure without a license) to provide fast-opening high-speed wireless data communications. Three 100MHz Band is: 5.15~5.25ghz, stipulates that its EIRP is not suitable for indoor wireless communication, 5.25~5.35ghz, the EIRP is not more than 30dBm, suitable for medium distance communication.
