Narrow bandwidth VOD system and method

The invention discloses a narrow bandwidth VOD system and method in order to reduce the experience difference caused by different accessed network bandwidths and resolve the problems of long order time and the like in a narrow bandwidth environment. By means of the scheme, the VOD access process of a terminal can be simplified, the interactive instruction length of a terminal VOD is reduced, and in the time shifting process of the VOD and an EPG, a cloud platform transmits playing information to a set top box through cloud terminal software, the set top box starts to apply for playing to a cloud media access platform, the cloud media access platform finishes interaction with a CDN system and sends channel shifting information to the set top box, and the set top box finishes video decoding playing and subsequent playing control.
