This year, noting that 2.0 becomes particularly popular, especially the time when 2.0 was still not popular to raise even more popular. However, I have to write P2P streaming media, in my view can really be IPTV2.0.
Let's look at P2P. The concept of P2P streaming media speculation from the start in 2005, a year down the light wind had more than 100 million dollars investment, the companies involved in this field up to dozens of much more. This is not the same P2P and BT, P2P streaming media in real terms is to P2P technology for video multicast, basically solve the problem of network video bandwidth, while dramatically improving the efficiency of the server. By P2P technology, the server send the video packets are often a lot of users with ip information when the information reaches a user's computer, the computer also been forwarded to the next IP, and so on. On the one hand the transmission of video information packets are not transmitted for a single user, each user they are communicators, like BT, video servers and bandwidth efficiency is improved efficiency, the calculation of the number of conservative 50-100 times, such as Tencent QQLIVE; the other hand, did not like the BT users occupy too much bandwidth, do not suffer from pressure from the telecommunications company, after all, a user can not and need to see two channels at the same time, the download may be a number of BT one or more threads at the same time, eat eat bandwidth, powerful. Thus, P2P video-on-demand solution to bring both the buffer, while not as crazy bandwidth BT, in order to find an excellent balance, and got rapid development.
As the broadcast reduces the user's interactive experience, so there carousel, a channel loop a class or even a video made and demand a similar effect. I started to pay attention QQLIVE from May's online, they have 20 million online since then to the current level of an average of 50 million online. If the count CCTV, pplive, uusee other video broadcast site traffic, the number of P2P live online at 300-500 million people, by the end of (New Year) is expected to reach 10 million online in the levels can be said of potential, market size more than casual games.
Turning back to look at IPTV.
IPTV (Internet Protocol TV OR Interactive Personal TV), also called interactive network TV, is the use of broadband network infrastructure to home TV or computer as the main terminal, set the Internet, multimedia, communications and other technology, and through Internet Protocol (IP) to home users, including digital television, including a variety of interactive digital media services, new technology. Many of the current description of IPTV, such as interactive, high definition, support for online games, and often high-definition television as a terminal, the current big push in the box is a real IPTV.
As for the IPTV license is very scarce, it is said in addition to other CCTV, Shanghai Media has also been a rather big box because no license was brutally halted. IPTV in China is actually the standard telecommunications and broadcasting in balancing interests, in the end is through the Internet to watch TV, or use the TV as a terminal to see the Internet, is the focal point of broadcasting and telecommunications disputes. So, although the license has been made, but the standards are still nowhere to settle down, a common argument is to triple play, broadcasting, telecommunications and mobile IPTV triple-play basis to talk about standards, it is also the interests of three parties has been unable to balance, so China has been stuck atop IPTV standards.
Radio and television sector is reluctant to allow users to use the Internet on television, so ads will be discounted, grand IPTV halt on the expected; the same time, radio and television also brings hope that the television through the Internet video, because it will increase advertising effectiveness , on-demand approach is not feasible, their bandwidth consumption and the revenue of this proportion. The emergence of P2P streaming, broadcasting and telecommunications to find a balance between. Can be very low cost to promote TV programs on the network, access to additional advertising effectiveness, play into the hands of median broadcasting sector. Can be seen over the past year, CCTV co-extensive and P2P sites, CCTV video of network is also growing, of course, does not include Tencent, the author seems to CCTV and Tencent's cooperation is sooner or later, after all, the result is win-win.
As such, broadcasting and telecommunications IPTV battle, have occupied a certain initiative. On the one hand, firmly controlled by the license, to play the game online through the TV IPTV form may not survive; the other hand, P2P and the content of radio and television units with large broad cooperation, this type into the Internet through P2P live video and impressive results .
Therefore, P2P streaming media, in my view be regarded as a IPTV2.0, regardless of their form of communication (full use of the user's resources), or its feasibility, IPTV has become the de facto standard, but from the effect point of view, have greatly promoted the television network.
I note, QQLIVE already there have been some high-definition video content, such as "Meteor Garden" has reached its Resolution 720 * 480 results have been very close to DVD results, while playing Shique and smooth, and QQLIVE of interactive features, but also make people feel that P2P streaming media in fact IPTV2.0.
I believe that P2P streaming media to help spread access to the Internet broadcast programs, but also will get its own rapid growth, to include IPTV2.0 standard is most appropriate that his.
