Abstract: It is disclosed a video processing method for generating a reverse video stream from an original video stream. Coded frames of the original video stream are buffered and decoded, whereby a reverse video stream is generated wherein the decoded frames are organized according to an order which is opposite to the display order of the original video stream. According to the method, a frame to be displayed is selected (602) between frames of the original video stream, selection of the frame being made based on the frames display order of the reverse video stream. The method further provides for checking (702-703) in a list of decoded frames if all reference frames of the original video stream necessary to decode the selected frame have already been decoded and the relative decoded frames are actually buffered.

Abstract: A receiver of analogue video signal having means for analogue video signal conversion has a receiving block (201) for receiving a first analogue video signal, a conversion block (202) for conversion of the first analogue signal into a digital signal, a buffer controller (203) of frame buffers, a video coder (204) for transforming the digital signal into an analogue signal of a second format, a receiver (205) for displaying the analogue signal of a second format and a processor (206) for data processing and controlling the receiving block, the conversion block, the buffer controller, the video coder and the receiver. The buffers controller (203) has three modules, namely, buffers (203b) linked together, a decoding frame controller (203a) and a displaying frame controller (203c). Certain frames in this device will be omitted when the output frames frequency is lower than the input frequency and displayed more than once when the output frames frequency is higher than the input frequency.

Abstract: A method for scrolling MPEG-compressed pictures consists in decoding a sequence of pictures (34, 35, 36) or any two pictures to be viewed by a MPEG decoder (5) and storing the sequence of pictures (35, 35, 36) or any two pictures in MPEG decoder memory. Then the sequence of pictures (34, 35, 36) or any two pictures is formed as a group of pictures (37), which is transferred to the first screen buffer (24) which is active. In the following step, any another compressed picture, after decoding in the MPEG decoder (5), is stored in a MPEG decoder memory as a decoder new picture and then is transferred from the MPEG decoder memory to the first screen buffer (24), where its edge line perpendicular to the intended scrolling direction is adjoined to the external edge of the group of pictures (37).

Abstract: The present invention relates to a device for control of display of video frames and a method for control of display of video frames, used in digital decoders/receivers of television signal, to which the signal is drawn in an analogue form.
