An image processing method for dividing a digital image signal into plural image signals corresponding to plural blocks constituting a single display screen, and performing block-by-block coding of the image signals of the respective blocks, comprises transforming an image signal of a coding target block to be subjected to coding into frequency components by frame-by-frame frequency transformation on a frame basis or field-by-field frequency transformation on a field basis; setting a processing order for coding the frequency components corresponding to the image signal of the coding target block, according as the image signal of the coding target block has been subjected to the frame-by-frame frequency transformation or the field-by-field frequency transformation; and successively coding the frequency components corresponding to the image signal of the coding target block according to the order which has been set. Therefore, in coding of an interlaced image or a specific progressive image in which frame DCT blocks and field DCT blocks coexist, a run length is increased, thereby improving coding efficiency.

Image processing method, image processing apparatus and data recording medium

Auxiliary information relating to digital data such as video and audio data is generated in synchronization with power-on, or generated according to an instruction from the user operating an information button or the like. Further, only an important portion of digital data is extracted by using the auxiliary information to generate reduced digital data, whereby the time and cost required for transmission is reduced.

A power control section, which turns a video/audio recording apparatus ON or OFF, outputs power control information. A video recording control section, which starts or stops video recording, outputs video recording control information. A signal input section allows moving picture data to be input. Based on the power control information and the video recording control information, an attribute designation section generates attribute information, which is supplied to a recording section. The attribute information contains a program number used for the classification of moving picture files. Any number of moving picture files which may be recorded after the power is turned ON and before the power is turned OFF are assigned with the same program number. The recording section records on a recording medium the attribute information as well as moving picture files representing the moving picture data which has been input via the signal input section. Thus, a file-by-file recording of moving picture data on a recording medium can be achieved in a manner which facilitates the subsequent finding of a desired file.

Apparatus and method for video/audio recording

In a video processing method, plural pieces of digital data such as video and audio data are inputted together with an instruction signal indicating whether or not the plural pieces of digital data are to be multiplexed, and the plural pieces of digital data are multiplexed when the instruction signal indicates that the digital data are to be multiplexed. The multiplexed digital data are then outputted together with a flag indicating whether or not the digital data are multiplexed. Therefore, when video and audio data are not multiplexed or when there is a scene description for handling plural pieces of video data, the video and audio data can be recorded or transmitted in a like manner as multiplexed data.

A decoding LSI adaptable to MPEG4 is provided with a padding means for performing padding on decoded texture data, an arithmetic decoding means for performing arithmetic decoding on coded shape data, and a composition means for compositing a plurality of texture data to generate composite image data. The padding means, the arithmetic decoding means, and the composition means are implemented by hardware circuits, i.e., a padding engine, an arithmetic decoding engine, and a composition engine, respectively. Therefore, the decoding LSI can perform high-speed decoding on a bitstream corresponding to plural objects, such as images, which are compressively coded by the MPEG4 coding method, with reduced cost of the hardware circuits performing the decoding process.

Image decoding apparatus and image coding apparatus

A picture is treated as an aggregate of plural objects, and the picture data is processed on an object-oriented basis to be multiplexed. A method of multiplexing data comprises the steps of (1) dividing the picture into a plurality of master objects, and identifying themselves as the master objects; (2) dividing the identified master object into smaller slave objects upon request, and identifying themselves as the slave objects, whereby a hierarchy is formed; (3) packetizing one of the identified master object and the identified slave object into a packet, and assigning a packet number to the packet, and (4) adding the hierarchical details as hierarchical information to the multiplexed data. In addition to this method of multiplexing data, a reproducing method of data multiplexed through this method of multiplexing data, and a, data reproducing apparatus using the reproducing method are provided by the present invention.
