Originally did a very long time audio and video codec things, should do a summary. Here is about the audio and video coding This kind of work gains and losses and trade-offs, in fact, the main is to give up, there is no reason, right when a listen. Let the readers judge for themselves.
Take video coding standard H., this is a good thing, after the standardization of video coding, compatibility issues "by laws", conducive to film, video and other dissemination. But it poses a big problem for researchers. That is the question of how companies compete under the same standards. Once the algorithm has been standardized, it loses its flexibility, and everyone, every company, is doing these things. At the same time, it has become a technical highland for big companies to compete for. Other companies, if they want to contend for it, are basically a struggle to consume. This kind of war, small companies and individuals cannot afford to fight. The biggest advantage for small businesses and individuals is focus and flexibility. Devote the most resources to a single point. Even if the big companies see, it does not necessarily look at the investment is not as tough as you, plus a layer of application and approval, do not be very efficient. This is where small companies or individuals are likely to win. From a strategic level, audio and video encoding and decoding, not suitable for individuals, insufficient strength or leadership of the lack of attention, talent allocation is not in place of the company to do
Finish the big plane, say the concrete executor. As a researcher, if you do this kind of work, if you'd better have a halo of Bull B (High education, Kochi Class), otherwise, even if you have the ability to make a relatively large improvement, because of the origin of the reasons, your income is very difficult to go up. If the entrepreneurial direction to the codec as a breakthrough, preferably in the chip company, or the company's main is related to the codec in the company to do a full-time codec, one up on the technology can be pressed on other companies, will not be reduced to the situation of consumption. Otherwise, the early evening will become a trap, you think it is very difficult to do, the company felt no output. Also, say the way out. If the strength is not enough, it is not recommended to use the opponent. Can reflect the difference in the place to do more work, such as: Network play fluent, easy to use, of course, the core difference point can also be content. At any time, the essence of competition is to occupy a differentiated point in the customer's mind. The more able to reflect this differentiation, the more customers can remember the live, remember the prison.
The trap and outlet of audio and video codec technology, a researcher's thinking
