Abstract:
1. Method of compressing a video sequence of images using an information processing apparatus in the form of a computer or a dedicated electronic compression module component, the method comprising: using a computer or dedicated compression module component to first compress the video sequence at a constant bit rate and determine a compressed image size value and an associated compression factor value for each image in the sequence; using said computer or dedicated compression module component to compute normalized values of compression factor values associated with each compressed image such that a normalized compression factor value is optimized in accordance with a size of a particular receiver buffer to be used for decompressing the sequence, wherein computing normalized compression factor values comprises using said computer or dedicated compression module component to perform calculations for simulating a data filling level of the receiver buffer and, using said computer or dedicated compression module component to compress the video sequence a second time using the computed normalized values of said compression factor value associated with each image.
