Latest Patents
One of Chang-dae Park's latest patents is a "Method and apparatus for normal reverse playback." This invention provides a method and apparatus for normal reverse playback of Group of Pictures (GOPs) of a bitstream stored in a storage medium from an Extended GOP (XGOP). The apparatus includes an MPEG decoder that reads a first bitstream corresponding to the XGOP and an (X−1)GOP from the storage medium. It decodes pictures of the XGOP and reference pictures of the (X−1)GOP using the read bitstream. Additionally, a frame buffer stores the pictures decoded by the MPEG decoder, and a display block shows the decoded pictures stored in the frame buffer. During normal reverse playback, the apparatus displays all the decoded pictures only once, ensuring that each display time of the decoded pictures is the same. This innovation allows for a linear search even during normal reverse playback.
Another significant patent is related to "Video scalers having reduced output memory and methods for selecting output memory size." This invention includes a video scaler that features a scaler core and an output memory with a reduced size. The scaler core scales input image data and stores the scaled image data in the output memory. The image processing apparatus can read image data from the output memory with a reduced storage time, enhancing efficiency in image processing.
