摘要： A restored image that has undergone motion compensation predictive decoding processing by an inverse conversion processing section and a motion compensation section is written for reference image use in a memory by a memory control section. The memory control section reads out a reference image that has undergone thinning out processing from the memory for use in decoding image data that has undergone bidirectional predictive coding and dual-prime predictive coding. The thinned-out reference image is interpolated and restored to a reference image required for motion compensation processing. Thus, even when the necessary maximum memory bandwidth is suppressed, the deterioration in image quality is made minute and partial.

摘要： An information transmit system includes a first communication element having a guaranteed quality required to transmit real-time information, and a second communication element different from the first communication element. The system also includes a transmission element for transmitting stored real-time information using the first communication element and for transmitting real-time data using the second communication element, where the real-time data using the second communication element has corresponding time stamps later in time than the real-time data transmitted by the first communication element. For example, a time stamp of the real-time data may be used to transmit the data in either a normal direction (using the first communication element), or in a retrospective direction (using the second communication element). The system also includes a storage element for storing the real-time data transmitted by at least the second communication element, and a switching element for monitoring a time stamp corresponding to the real-time data transmitted from the first communication element and a time stamp corresponding to the real-time data transmitted from the second communication element. The switching unit switches the output of the real-time information transmitted from the first communication element, to the output of the real-time data transmitted from the second communication element that is stored in the storage element, when the time stamp for reproducing the real-time data stored in the storage element has been reached.
