20080205510 | Apparatus and method for converting a compressed video stream with preview of converted stream - An apparatus by which a user can easily set a parameter for conversion when a compression encoding system of video stream is converted is provided. A particular period in a first video stream is repeatedly reproduced to convert the reproduced portion into a second video stream in real time. At that time, the user checks the image quality after conversion on a preview screen and sets a desired conversion parameter. A local decode image is output to the preview screen. Thus, the circuit configuration is simplified. | 08-28-2008 |
20090034625 | Image Decoder - The present invention relates to an image decoder which implements high speed image decoding with a low cost and simple configuration.
