摘要： A method, apparatus and system for providing a video service of a video service system including multimedia video in real time to a mobile terminal connected by a wireless network. A video frame coded by a coding scheme is transmitted to the mobile terminal for decoding and display. The coding scheme may include a first coding scheme and a second coding scheme used together at a predetermined ratio according to the mobile terminal demanding the video service. A server typically receives coding scheme change determining information from the mobile terminal in order to determining whether or not to change the coding scheme for the video frame during transmission of the video frame. The changed coding scheme can be used to transmit the video frame to the mobile terminal according to the result of analyzing the coding scheme change determining information.

摘要： A method and apparatus for generating a thumbnail image are provided so that the out-of-focus (OOF) information can be ascertained from looking at the thumbnail. An input image is decoded, and a degree of the amount of OOF of the decoded image is measured (OOF information). There is a determination as to whether or not there is an EXchangeable Image File (EXIF) information about the input image. In the presence of EXIF information, a thumbnail image is extracted from the EXIF information and as much an OOF effect is applied to the thumbnail image in accordance with the degree of OOF. In the absence of the EXIF information, a thumbnail image is generated by scaling down the decoded image at a down scaler and applying as much of an OOF effect is applied to the thumbnail image in accordance with the degree of OOF.
