A data processing apparatus is provided with a data obtaining unit which receives a network signal sn on a network N and obtains distributed audio data Dau in which copyright information or the like is embedded, and a control unit which obtains information indicating a watermarking method which has been used when embedding the copyright information or the like in the audio data. The embedded information is extracted by an appropriate watermarking method according to the obtained information indicating the used watermarking method. The extracted information is again embedded in the distributed audio data Dau by using a predetermined watermarking method, and thus obtained audio data is recorded on a recording medium. Therefore, regardless of the watermarking method used for embedding the copyright information or the like in the distributed audio data Dau, the distributed audio data Dau can be appropriately reproduced by reproduction apparatuses as domestic electrical equipment, according to the embedded information.

The invention relates to a binocular stereoscopic vision-based stereo matching method. The method includes the following six stages: Gaussian pyramid construction; cost calculation matching and cost aggregation; cost fusion matching; disparity computation; disparity map repair and void filling; and disparity refinement. Laplacian pyramid transformation is additionally adopted in the cost aggregation stage. An edge-protection-based interpolation algorithm is used in the disparity map repair and hole filling stage. A weighting and bilateral filtering combination-based disparity refinement method is additionally adopted in the disparity refinement stage, so that a high-accuracy disparity map can be obtained. The calculation amount of the method of the invention is moderate; matching results at different scales are fused, improvement is made in the cost aggregation stage and the disparity refinement stage, and therefore, a better disparity map can be obtained; and the method has certain robustness to illumination, external noises and the like.

There is provided a content use management method capable of preventing unauthorized distribution of a content and improving user-friendliness. In this method, the same group key is stored in a secure device (400) and a playback terminal (500). Moreover, a license issuing application is received from a license distribution server (200) and stored in the secure device (400). After this, a license encrypted by the group key is sent to the playback terminal (500) and the license encrypted by the group key is stored in the playback terminal (500). Upon playback of the encrypted content, the playback terminal (500) decrypts the license by using the group key and acquires the content decryption key, thereby decrypting the encrypted content. Even when the encrypted license flows into the network, it cannot be decrypted by a playback terminal not having the same group key and the copyright is protected. Moreover, the playback terminal (500) which already holds the group key and the license encrypted by the group key does not need the secure device when reproducing the encrypted content.

The apparatus for embedding a wavelet based audio watermark includes: a framing unit for dividing an input audio signal into small signals with a regular length; a discrete wavelet transform unit for calculating an mean value of wavelet coefficients by transforming the small signals based on a discrete wavelet transform; and an embedding unit for changing the calculated mean value according to a watermark where a synchronization signal is inserted and inserting the watermark into the audio signal.

A copyright of a content is protected by preventing creation of illegal copies of the content and the content is prevented from being transmitted beyond a range of personal use in a process to transmit the content through a LAN. Before transmission of a content, a content transmission apparatus and a content reception apparatus perform a determination of authentication information available in a predetermined command accompanying authentication information, or an authentication determination based on a time until reception of a response to a predetermined command request accompanying predetermined authentication information. If the authentication is unsuccessful, the requested content is not transmitted to the content reception apparatus. With such arrangement, it is possible to effectively protect a copyright when a content is transmitted by way of a network.
