ABSTRACT:
The present invention relates to a menu picture generating method and to a recording device for recording a menu picture on a record carrier (20), wherein a key frame picture is scaled and then compressed before being assembled by a slice replacement operation. The entire menu picture assembly operation is performed in the compressed picture domain, wherein no pictures need to be decoded and only small part of the menu picture, corresponding to the scaled key frame picture, needs to be encoded. Thereby, the normal encoding-decoding pipeline of the recording device is not required for menu generation, such that hardware and software requirements can be reduced.
