SYSTEME ET PROCEDE DE CODAGE VIDEO

摘要

The system (100) has a receiving module (101) receiving input data to receive a current image. A dividing unit (103) divides the image into macro-blocks. An estimation module (105) estimates movement vectors based on the macroblocks of the current image and preceding/posterior image. The module (101) receives localization and dimension information, from a program interface of operating system e.g. XFree86(RTM: Xwindow type unix), of a modified zone of the current image. A transmitting unit (104) uniquely transmits the macroblocks belonging to the modified zone to the module (105). An independent claim is also included for a video coding method for coding successive images of a video sequence.
