An electronic apparatus stores in a graphics memory a first and a second graphics object. An OSD processor generates a first digital stream which represents the first graphics object. The second graphics object is converted into picture data, for example by a main controller, and these data are written to a picture memory, from which a second digital stream is generated. A mixer combines the first and the second digital stream into a video signal to be displayed.

Electronic apparatus generating video signals and process for generating video signals

A video apparatus has a digital decoder having a first memory on an internal bus and linked to an OSD circuit and to a second memory via a main bus. The video apparatus comprises means for realizing a DMA transfer between the first memory and the second memory. A process for controlling such a video apparatus is also described.
