    摘要: A scrambling apparatus and method are provided for increasing randomness without damaging compression efficiency of total video data by selectively and randomly performing conversion when converting motion vector codes of compressed video data into other motion vector codes indicating other motion vector values, and more particularly, by performing conditional conversion only if a predetermined condition is satisfied when selective conversion of motion vector codes is performed. The scrambling apparatus includes a conversion motion vector code table generator generating a conversion motion vector code table comprising motion vector codes obtained by converting motion vector codes corresponding to motion vector values of input video data in a standard motion vector code table; and a conversion controller randomly determining whether a certain motion vector value is encoded using the conversion motion vector code table or the standard motion vector code table.

    摘要: A multimedia device having a function of backing up received broadcasting contents in a home network environment and a method of backing up the broadcasting contents. The multimedia device includes a local storage unit for storing received broadcasting contents, and a storage controlling unit for controlling storage of the broadcasting contents. When a space of the local storage unit is insufficient or when a user requests a backup, the storage controlling unit controls the device to transfer some of the stored broadcasting contents to a backup device. Accordingly, the multimedia device backs up the received broadcasting contents in various backup devices, thereby efficiently controlling the storage space of the local storage unit. Also, the multimedia device can prevent the backed-up contents from being arbitrarily reproduced or copied by another unauthorized multimedia device.

    摘要: A method and apparatus for effectively managing a plurality of licenses are provided. The method includes selecting a value, which corresponds to license information, from a Hash mapping table; selecting a node corresponding to the license information from a tree structure corresponding to the value; and searching for a license by using license location information contained in the node. The apparatus includes a Hash function processor which computes a first value corresponding to the license information using a Hash function; a controller which selects a tree structure corresponding to the license information based on the first value computed by the Hash function processor; a tree structure manager which selects a node corresponding to the license information from the tree structure; and a storage unit which stores the license.
