Internet video is any kind of movie or video that has been encoded to play over the Internet. It comes in many formats, some of the most popular being ASF, WMV, RM, RMVB, MOV, Divx.
Many may well know that the Internet video is very small , but the quality is less than satisfying. The reason? Well, the video is among the most apace consuming digital media.
The bigger and better the video, the larger the file size is. In order to shrink a broadcast-quality video ,down to just a few megabytes, sacrifices need to be made in the size and quality of the images.
ASF, that is Advanced Streaming format, is a video format developed by Microsoft as a competitor to Real Player. Users can play the video with Windows Media Play. As it is compressed using MPED-4 arithmetic, the compressing rate and quality of the image are quite good. Since high-rate compression will facilitate the transmission of the video streaming, at the cost of degraded image quality, ASF can be less stable than VCD.
RM, Real Media, an audio/video compression criterion established by Real Networks. Netizens can use RealOne Player or RealPlayer to relay network audio/video sources up to RealMedia technological criteria.An outstanding merit of RealMedia is its able to set different compressing ratios in accordance with the variable transmission rate of internet, so as to make come true real-time propagation and play of video data with relatively low-rate internet, that is to say enable users to watch videos on-line.
As for the distinctions between RM and ASF, generally speaking, RM video is a bit more smooth, while ASF has its edge in definition.
For all these formats merits and demerits mentioned above, there is another aspect to be concerned.
