摘要： An apparatus and a method of changing a bit rate of a compressed image bit stream by changing a codeword so as to easily change the bit rate and reduce a changing loss. The apparatus for changing a bit rate, in which an input bit stream generated by an image compression encoding method is changed into an output bit stream having a desired bit rate, includes a changing codeword determiner which selects codewords to replace the codewords of the input bit stream, and a codeword changer which changes the codewords of the input bit stream into the codewords selected by the changing codeword determiner. The method and the apparatus can be applied to image services provided through the Internet and receiving apparatuses supporting the Personal Video Recorder (PVR) function. Particularly, the method of changing the bit rate of a compressed image bit stream changes the codewords of input transform coefficients so as to easily change the bit rate and reduce the changing loss.

摘要： A security method and a security apparatus are disclosed which use a self-generated encryption key. The security method includes the steps of: generating an encryption key; decrypting pre-encrypted data using a pre-stored manufacturer key; and re-encrypting the decrypted data using the encryption key. The security method and apparatus minimize external leakage of data by self-generating the unique encryption key. Since the encryption keys are unique in each set, set binding is possible.

摘要： A method of hierarchical image indexing which extracts representative images of a TV program and generates a hierarchical index image guide of the representative images, and an apparatus therefor. Respective images at predetermined times are extracted from a predetermined program. A hierarchical index is allocated to each extracted image and the indexes are mapped to locations of transport stream packets. A tree of images having the allocated indexes is constructed as a hierarchically indexed Image guide (HIIG). When a stored program is to be reproduced, a location desired to be watched is selected in the HIIG, and from the selected location, reproducing and trick plays (FF, rewind) are enabled such that a user easily searches the program and begins viewing the program at the searched for location.

摘要： A method, medium, and apparatus for deleting and/or restoring time-series contents stored in a recording medium. When the time-series contents are stored in the recording medium, deleting of data that is present in a first area of a recording medium includes periodically inserting a time stamp into the contents, generating deletion data positional information based on the time stamp, the deletion data positional information representing a relative position of the deletion data within the contents, storing the deletion data positional information and the deletion data in a second area of the recording medium, and designating the first area as overwritable on the recording medium. Even if the recording medium is reloaded in another disk drive and under another operating system, data deleted from the recording medium can be easily restored.
