摘要： First, a set of seed images that tally with each other are prepared (S101). Next, a set of threshold matrices are created from the set of seed images (S102) Next, a plurality of tally images are created from an input gray-scale image by using the set of threshold matrices (S103). The tally images are combined, whereby the confidential image is decoded.

摘要： This invention aims to form hierarchies of coded moving picture data in a simple method or apparatus. An I, P and B separator separates I, P and B picture data from coded moving picture data. A first to a third header/low/high separator separate headers and low and high DCT data components of the separated I, P and B picture data, and hierarchy forming means assigns the outputs of the separators for a 1-st to a 6-th hierarchy by supplying the outputs to packetizers therefor. The packetizers packetize the assigned data, and send out the packetized data on communication lines for the 1-st to 6-th hierarchies. For example, low frequency components of I picture data are provided as the 1-st hierarchy, high frequency components of I picture data are provided to the 2-nd hierarchy, low frequency components of P picture data are provided as the 3-rd hierarchy, high frequency components of P picture data are provided as the 4-th hierarchy, low frequency components of B picture data are provided as the 5-th hierarchy, and high frequency components of P picture data are provided as the 6-th hierarchy.

摘要： An encoding control unit obtains a quantization step size and a video encoding rate Rc on the basis of various kinds of conditions including a transmission time and image quality specified through an input unit by a user, and property of image contents from a signal compression processing unit. Next, the video encoding rate Rc is compared with a network transmission rate Rt which is obtained through a network IF unit. Then, if the transmission rate Rt of the network is smaller than the video encoding rate Rc and is present in the range any of values of which is equal to or larger than the value smaller than Rc by a predetermined quantity, then the quantization step size is corrected in such a way that the video encoding rate Rc is equal to or smaller than the transmission rate Rt of the network, or in such a way that the video encoding rate Rc is increased. As a result, it is possible to provide an apparatus for transmitting dubbing data of a digital VTR which is capable of suppressing the degradation of a transmission throughput.
