METHOD AND DEVICE FOR GENERATING A VIDEO SIGNAL |
摘要 |
A method for generating a compressed video signal is described, that is suitable for use in trick play such that an interlace effect is effectively avoided. In a first embodiment, images are displayed repeatedly by generating at least one empty repeat picture, wherein the first empty repeat picture is an interlace elimination picture (E2(RT®B; RB®B)) referring back to a bottom field memory (MB) in respect of the top frame (T2) as well as in respect of the bottom frame (B2). In a second embodiment, applicable in the case of a field-based coded video sequence, the bottom field (BI1) of an original picture (X1) is replaced by an empty repeat field (EB(RB®T)) referring back to a top field memory (MT). |
