The invention provides a virtual reality synthesis method and a terminal. The method and the terminal possess: a first signal source which comprises at least one element of one audio frequency, two videos and pictures; at least one device which externally inputs a second signal including at least one element of the audio frequencies, the videos and the pictures; at least one element which forms the second signal and can separate the second signal. The elements or all information of the first signal and the second signal are superposed, synthesized and output through a three-dimensional terminal. A synthetic and output result can be sent through network. The invention has the following advantages that: decoration or superposition of special efficiency can be achieved to oneself or others through using video and audio frequency contents of database on network or the video and audio frequency contents of other users; a three-dimensional virtual reality effect can be realized; operation is simple; there is no need to increase devices; costs are low and effects are good.
