Although the application of convection media is growing, we can also feel the panic of the network company's convection media application. For them, the hypertext markup language (HTML) and the other end of transmitting audio or video signals to the world can also be understood, and the streaming media is completely different from these two, it is generally surprising like magic.
In fact, the streaming media is simple, and now we can easily create or apply streaming in our own URL. Most online companies will find that the streaming media is not terrible compared to their initial application of HTML or JavaScript language, the only challenge is to understand the choices and development directions provided by convection media industry.
What is a streaming medium?
To understand the role of streaming, you need to understand the operational mechanism of WWW. The web server is typically described as "stateless". It accepts information requests, issues information as soon as possible, complete processing, disconnect, and turn to other users' requests. In the client, your browser handles the received information, collect the information on the screen until you click on the link again to activate the web server again. The network transmission between the server and the client is just an instant fast exchange, then disconnect.
This "stateless" manner is well suited for graphics or text, which can easily display them on the screen. But for dynamic images and sounds, it is very problematic, image, video, animation, and sound with time elements, which increases the capacity of the file. In the "stateless" mode, the network user needs to download the entire video clip before viewing. But even a large file of small fragments, this waiting is unbearable, so other solutions are needed.
The goal of using streaming media is to break through the WWW restrictions, using Internet-based technologies, transfer media data to the user when viewing. This is very like watching a TV or listening to the radio, receiving them at the time of seeing images or hearing the sound. Therefore, the streaming media is a continuous connection rather than the "stateless" data connection.
The size of the fragment file can be adjusted with time, so it is no longer important. But the original digital sound and video files are still very large, so they must be compressed by modulating the mediator or a local area network. The compressed flow medium makes a small number, and of course, the quality of the image and sound is also reduced.
As with other Internet-based transmission, the application streaming also needs to be folded, and how many data may be considering before the streaming media is clearly transmitted to the modulation mediator or a local area network user? Which discard mode is best based on the integrity of the segment file? How to compress files to the file? These are very interesting questions.
What is the quality?
Media producer, especially those with TV production background, often criticize the quality of stream media. They spend the understanding of the convection media, think that the streaming does not pay attention to quality, but only pays attention to access, and is to receive content from the rest of the world in the office of somehop.
Surprisingly, most Internet users do their best. Throughout the history of various media, the new media is always phased to see the old media, but the new media can provide the function of the old media. For convection media, it is used for access, the images and sounds may be very bad, but when the network user clicks on the link, you can get the required content, this is its uniqueness.
Fortunately, the flow tool is rapidly developing and is more and more powerful. It is far better than 6 months before it is better than 6 months, and is continuing to improve at an amazing speed.
How to use multiple formats?
One of the important factors that prompted any technological improvements are competition, and network companies are always unfixed. What should I do?
Looking around, you will find that the world is full of different: different types of computers, different types of pets, different models of cars, different languages, religions and nations. Human is a group that has no unified standard. In each crowd, there are always a few people who are different. Thus, although the standard is an important goal, humanity (and money) will never resolve. Streaming media is to make you choose. What format is best for you? What technology do you want to adopt?
Where is the streaming media?
In people's impressions, traditional networks are not booming. Of course, there is already improved in background technology such as database integration and server, but for traditional media manufacturers or designers, the network is rapidly turning into a far-reaching area.
The streaming is the next milestone. Multimedia networks are much more powerful than we know today, and new streaming media, techniques, and methods will replace a boring network design through multimedia mode. (Jiang Guoyu compilation)
