1. The three major platforms of streaming media, RealNetworks, Microsoft, Apple, and they occupy 80% of the market, both technically and in the market are relatively perfect. We will further evaluate the three major streaming media platforms, RealNetwork, Microsoft and Apple. The purpose of the evaluation is to let readers who are new to streaming media have the opportunity to choose the most suitable streaming media platform for the website they design or the company they work for without misjudgement-it took millions of dollars I found that I only needed one-tenth of the functions; or I chose a free platform and found that I could not install it without the assistance of experts-these are common lessons for the author. In fact, all streaming media platforms, despite their advantages and disadvantages, do the same thing in their original work. The first is to compress and encode the general non-stream format into a stream format file, and then send it to the streaming server for management and sending To the designated audience (user), after the user downloads, the music or video is played through the stream decoding program. To understand the differences between the three streaming platforms RealNetworks, Microsoft, and Apple, it is best to understand them from the perspective of completeness, compatibility, and insufficient support from manufacturers.
1. Integrity
RealNetworks has been developing streaming media for a long time, and its product line is quite complete. This is also a major advantage of RealNetworks. From the entire process of streaming media, from the beginning of creation, transmission, servo, to download and playback of the back end, RealNetworks is in every link There are corresponding products, and each product has two versions. The Basic version is free to download and has limited basic functions. If you want the full function, you need to buy the Plus version. The Plus function is complete and sufficient to provide professional use.者 使用。 Use. The completeness of the product is very important for professional streaming engineers (Encoding Engineer) and large websites with thousands of netizens. From the author's point of view, RealNetworks' product line is complete and fully functional, and can provide a comprehensive solution (Total Solution) for professional users.
Although RealNetworks provides a complete product line, supporting functions are also available from start to finish, and its high price is not easily affordable by ordinary non-professional users. For Start Kit), the price of the entire set equivalent to US $ 2,999 is not cheap for SMEs and individual users. And the maximum number of RealServerPlus included in the solution is limited to 60 people at the same time, which is definitely not enough for websites and large enterprises. If you want to upgrade to Real Server Professional or Real Server Intranet that can serve more people, the price of the entire RealNetworks system Will easily exceed several hundred thousand yuan. In addition, the upgrade speed of RealNetworks products is very fast. From RealSystem G2 in 1997 to RealSystem 8 in 2001, every time you upgrade, enterprises will be caught in the problem of whether to spend money to upgrade. However, if purely considering the integrity of the product, RealNetworks will be the first choice.
Microsoft's windows media streaming system platform also provides a fairly complete product line, from windows media authow, windows media asf indexer on the production side, to windows media encoder for encoding, windows media server for servo transmission of content, and protection wisdom. The windows media rights manager of property rights just wants to be compared to RealNetWorks, and the depth of functions of each product is slightly insufficient; of course, for a completely free streaming platform, such functions are indeed invaluable, and windows media is more than RealNetWorks A servo load simulation program (Load-simulator) is provided, which allows the system to simulate the actual line load and test the limit of the system's servo capability to avoid the system from being unable to load when too many users rush in. Windows media encoder also provides a screen capture function. This screen capture function can record all the contents of the large and small windows and the process of cursor movement in highly compressed streaming video files. It is a very useful tool for users who need education and training.
You can find descriptions and answers to most windows media on the website. Another disadvantage of windows media is that its tools and instructions are scattered everywhere. There is no centralized website to find all. To find all the application tools and user manuals of windows media, users must search Microsoft's website (a very large website). Here are most of the tools for readers, except that the windows media server is on the Windows 2000 Professional Edition or Windows 2003 Professional Edition CD, and the rest can be downloaded for free at http: //. As for the usage instructions and troubleshooting, users can go to the website to find it faster; because RealNetWorks does not have a guide from editing, encoding, uploading, servoing, downloading, broadcasting and other steps, users may have to try several combinations , Plus the English website query of Microsoft, you can find the most suitable way for you. But you pay for every penny, do n’t you? For individuals or small and medium-sized enterprises with no software budget, it is quite cost-effective to buy a copy of Windows 2003 Professional Edition to legally own a complete streaming media platform; so now this solution has more and more users in the market !
The latest version of Apple ’s QuickTime is 7.0, and pple ’s streaming platform is at a disadvantage in terms of integrity. Since Apple itself only has QuickTime (Darwin) StreamingServer (an OpenSource server architecture) and AppleQuickTimePro (US $ 29.99), users must purchase Sorenson Produced VideoPro2 encoding program ($ 499) to convert audio and video content to QuickTime streaming format. If you want to broadcast live, you must use the same optional SorensonBroadcaster ($ 199) to stream the content, and if you want to edit the audio and video content into The MultipleBitRate stream format that can correspond to different bandwidths, users must buy a set of MediaCleanerPro ($ 599) produced by Terran Interactive; such a set is really not very convenient for users, but in sum, it is still better than The RealNetworks solution is cheap and there is no limit to the number of users, and for Mac users, the QuickTime format is always their favorite!
compatibility
In terms of compatibility, RealNetworks can be said to get the highest score, and it is the only platform that can span WindowsMac and Linux, Solaris, HP / UX user streaming services. For consumers who want to attract the most, RealNetworks The platform can guarantee the highest compatibility. Relatively speaking, Microsoft's support for platforms other than Windows is far worse than expected. For WindowsMediaforMac, its launch speed has been slower than that of WindowsMedia7forPC for nearly a year, especially for Linux, which has recently threatened Windows. Needless to say-no support.
RealNetworks is also worth mentioning that its RealServer can provide the most various streaming formats. In addition to RealNetworks ’RealMedia format, it also supports Apple ’s QuickTime format, which means that QuickTime users do not have to use Yangchun. The AppleDarwinStreamingServer is used to set up the streaming server, and the same can be transmitted with the advanced RealServer; this is to let WindowsMedia, which only supports its own format, sigh.
