摘要： The present invention relates to an information processing apparatus and method which make it possible to transmit image data with high quality and low delay in more versatile situations. A control unit 111 obtains negotiation information including a transmission-allowed bit rate of a transmission line 103, which is defined in a standard, information regarding a receiving apparatus, or a measured value of the transmission-allowed bit rate, controls whether or not to encode image data and transmit the encoded image data, and performs settings in encoding, such as a resolution, a bit rate, and a delay time. Also, an encoding unit 113 controls a decomposition number of a chrominance component in accordance with the format of image data to be encoded. The present invention is applicable to, for example, a communication apparatus.

摘要： The present invention relates to an encoding device and method, a decoding device and method, and a transmission system, wherein image data which is subjected to compression encoding and sent out can be output as decoded images at the receiving side in a short time. At the time of wavelet transformation, filtering processing is performed in increments of lines, with a number of lines, whereby coefficient data for one line worth of lowest band component is generated, as an increment. At the first time, processing of line No. 1 through line No. 7 is processed, highband component coefficient C1, coefficient C2, and coefficient C3, and lowband component coefficient Ca, coefficient Cb, and coefficient Cc, are generated at division level = 1, and at division level = 2, highband component coefficient C4 and lowband component coefficient C5 are further generated from coefficient Ca, coefficient Cb, and coefficient Cc. These coefficients are rearranged in the order from lowband to highband, and supplied to a synthesizing filter. The synthesizing filer performs filtering processing of the coefficients in the order in which they were supplied, generates image data, and outputs.
