An image processing apparatus is configured to have units for compressing and expanding image data and an arbitrating unit for arbitrating control units for executing image processing so that the compressing and expanding units are located between the arbitrating unit and the control units respectively. The apparatus further includes the circuits for compressing and expanding the image data in a reversible manner and a nonreversible manner so that the compressing and expanding manner may be switched according to the image processing condition. When treating a large amount of image data, this configuration makes it possible to reduce the number of accesses to memory and make effective use of a bandwidth, thereby being able to reduce the power consumption. Since the bandwidth is reduced and the random access to memory is made possible, more image processing capabilities may be provided so that the operability of this apparatus is enhanced.

A refresh area is taken advantage of when a series of images are coded using Intra-frame coding and Inter-frame coding, a partial area of an image being forcefully Intra-frame coded (Intra MBs) in the refresh area. As the prediction mode for prediction of the Intra MBs inside the refresh area, a prediction mode is selected where the prediction is executable based on only the image that exists inside the refresh area.

The present invention relates to an image decoder which implements high speed image decoding with a low cost and simple configuration. By a stream dividing module, an input video stream is divided in units of frames as a plurality of frame rows for distribution. Each of plural decoders generates decoded images by decoding a distributed frame row. Of the decoded images generated by the decoders, reference images to be referred to when a subsequent frame is decoded is stored in a reference image frame memory. A timing control module receives information about stream distribution from the stream dividing module and controls the respective timings of decoding frames distributed to the decoders.

A video transmission device comprising: a reference signal generation unit which generates a reference signal based on time information; an imaging unit which images a video signal based on the reference signal generated by means of the reference signal generation unit; a compression unit which performs digital compression encoding of the video signal imaged by means of the imaging unit; a network processing unit which receives, from a network, time information and phase information about a reference signal in regard to the time information and, also, transmits the digital compression encoded video signal; and a control unit which controls the reference signal generation unit and the network processing unit. Here, the control unit modifies the phase of the reference signal generated with the reference signal generation unit in response to the time information and the phase signal received with the network processing unit.

In a method of simultaneously transmitting a plurality of uncompressed video signals, when transmitting different video signals for the right eye and the left eye using a 3D video signal transmission format, information representing that a plurality of video signals are being transmitted is added to a packet of additional information related to the video signals. A transmission method of audio signals at the time of simultaneously transmitting a plurality of video signals is provided. Further, the present invention is consistency with 3D video signal transmission in which two video signals for the right eye and the left eye are transmitted.
