摘要： The present invention provides a scrambled compressed data distribution device that can perform a high-resistance scrambled compressed data distribution by selectively using a plurality of types of scramble information and a playback device thereof.A scrambling section scrambles compressed data by unique one of a plurality of scrambling methods. A hash value calculating section determines a hash value based on data b in a position where digital watermark data is not embedded, and an encrypting section encrypts the hash value with a secret key Sk(n) corresponding to the scrambling method and outputs an encrypted hash value c. A watermark data embedding section embeds the encrypted hash value in a watermark data embedding position of the data b and transmits the same as a compressed data stream d.

摘要： A first encoding section encodes an original picture S(1) and outputs it to a communication line of a first channel. The encoded image data is decoded in a first decoding section. This decoded data C(1) is input to a first compensation section. The first compensation section uses the original picture S(1) and the decoded data C(1) as the input, and performs calculation of the following expression (1) to thereby generate a first compensated original picture S(2): S ⁡ ( i + 1 ) = ( S ⁡ ( 1 ) × i - ∑ k = 1 i ⁢ C ⁡ ( k ) ) / ( N - i ) + S ⁡ ( 1 ) ( 1 ) wherein i=2 to N, and N denotes the total number of channels in image encoding. The first compensated original picture S(2) is encoded in a second encoding section and output from a communication line of a second channel. Thereafter, similar operation is performed for the total number of channels N. According to this invention, there can be provided an apparatus for dividing, compressing and transmitting video data that can sufficiently improve the encoding efficiency, without requiring preferential transmission of the basic data.

摘要： When a predetermined amount of data is written in a file of a magnetic disk, a data pack creating section creates a data pack. A plurality of transmission threads allocates the data pack, and transmits it to a plurality of receiving threads via a connection. The received data pack is written in a magnetic disk. The transmission threads register a data pack, a transmission starting flag and a file position of the data pack in a transmission control table included in a transmission control section. The transmission threads are operated independently from each other, and when finishing a transmission of the allocated data pack, first, investigate a retry queue, and then, transmit a data pack if the data pack exists in the retry queue, and request a data pack from the data pack creating section so as to transmit the data pack if no data pack exists, in the retry queue. Therefore, according to the present invention, it is possible to provide a data transmission apparatus which can transmit a high quality file at a high speed.

摘要： An H. 261 encoder outputs coded video data together with a mode selection signal and a judging signal as to discarding or not of a packet. A packetizer receives the output signal from the H. 261 encoder and separately packetizes motion data and DCT data in the input coded data. A gateway judges whether packet including the DCT data is discarded or not with reference to the packet discarding judging signal and also to the bitrate of the network to which the gateway is connected. The gateway thus can effect bitrate conversion according to the bitrate of the network with a simple construction. The gateway may selectively discard high frequency component packets without discarding low frequency component packets, or it may not discard first importance component packets having greater influence on picture quality and selectively discard second importance component packets having less influence.
