Video encoding device and method
A video encoding device capable of performing a near-real-time encoding process while restraining deterioration in image quality. A first encoding section encodes a video signal to generate a first stream and extracts stream information including space- and time- related information of the video signal. A stream buffer stores video scenes of the first stream which correspond to a partial time of the video signal. An encoding control section analyzes a code generation rate and motion information from the stream information to generate encoding control information. A second encoding section encodes the first stream read from the stream buffer, in accordance with the encoding control information, to generate a second stream. The stream buffer stores multiples video scenes of the first stream by means of which a scene change can be detected as an information rate change.
