What is the difference between video streaming, video conferencing, and video on demand?

The live video system achieves three forms of live broadcast:

The first live event, the live broadcast of the meeting. Through the camera, acquisition equipment (video) to collect the activity of the scene into a data stream to the Live software (ffmpeg), live software to collect compression transcoding push to the server, published to the Internet. Users this is through the Internet immediately without at the event site can also see even thousands of miles away from the live situation, such as the presence of their own;

The second is TV signal live (cable TV, satellite TV, etc.). A variety of signals (limited, digital, satellite and other video signals or data content) automatically batch codec, to achieve the unmanned self-guarding of the hour (or longer) live recording broadcast and automatically upload the release;

The third is virtual live/carousel, which loops the existing files in a certain order. Can self-control program, real-time signals and existing video files to do mixed programming live. Such as

Video-on-demand is a replay of previous video files.

The most important function of video-on-demand system is that the video files of various formats (such as Vcd/dvd/wav/avi/mpg/mp3) can be transcoded into the streaming media format (asf/wma/flv etc.) which is supported on the network, so as to realize the unified management and sharing utilization of AV content.

Of course, in the data format transcoding process can be the video encryption, video management, and viewing permissions settings.

Video conferencing, using mpg-2 technology and streaming media technology is completely different. is through the interaction of the video, let the participants communicate with one another, pay more attention to the interactive aspect, the application surface is also for the user group of small internal, with confidentiality. There is no way to record and review the communication process to save. And the participants of the communication must each install the client, must have enough bandwidth and professional hardware to support. The number of people who have been put on the big but used is limited.

The sharing and utilization of resources in the entire enterprise cannot be achieved.

The video Broadcasting system can be used in combination with the Video conferencing system, OA system, and so on, which effectively supports the internal conference communication and greatly expands the application value of the existing system.
