The user ID updating method includes: (a) collecting unauthorized access attempt information for a user ID; (b) creating a user ID update policy for an encoded user ID obtained by encoding the user ID, according to the unauthorized access attempt information collected in operation (a); (c) storing the user ID update policy created in operation (b); (d) loading the user ID update policy stored in operation (c) and determining whether or not to update the user ID; and (e) creating a new user ID if it is determined in operation (d) that the user ID should be updated, and changing the user ID to the new user ID. Therefore, it is possible to ensure security for user IDs, by dynamically creating and updating user IDs according to security environments. | 09-17-2009 |

20090161762 | METHOD OF SCALABLE VIDEO CODING FOR VARYING SPATIAL SCALABILITY OF BITSTREAM IN REAL TIME AND A CODEC USING THE SAME - Methods of coding a bitstream in which the frames are encoded for enabling a spatial resolution is changed in real time, extracting the bitstream by adding a signaling message indicating that the spatial resolution is changed, and decoding the bitstream in which the spatial resolution is changed in real time after actively detects whether the spatial resolution is changed without additional information, and a codec using the methods are provided. Therefore, if the network has the restricted environment that the resolution is changed in real time while a video encoding and decoding or if there is a need to output the video whose the spatial resolution is partly changed in the decoder, the present invention provides methods to actively cope with the spatial resolution change of the video so as to efficiently watch the video. | 06-25-2009 |
20090222486 | SVC FILE DATA SHARING METHOD AND SVC FILE THEREOF - A method of sharing data of a scalable video coding (SVC) file and the SVC file are provided. The SVC file includes: a scalable base track including at least one scalable layer entry each storing metadata of the at least one scalable layer; and at least one sub track generated based on the scalable base track, which includes identification information of the scalable layer that is a basis of generation of a sub track among the scalable layers and identification information of the scalable base track instead of the scalable layer entry. Accordingly, when an SVC coded content is stored as a file, it is possible to reduce a storage capacity by avoiding duplication of common data and to provide convenience when the stored content is reprocessed by allowing a relation of tracks correlated to one another to be represented. | 09-03-2009 |
