摘要： A conventional coding method has a problem that for frame-by-frame reverse playback, data must be once decoded in a forward direction and thus a larger volume of data must be processed and a larger volume of memory is required.By recoding a forward predicted picture and a backward predicted picture for a frame in a bit stream, the bit stream can be played back reversely frame by frame easily. By the use of this method for multi-viewpoint video coding, a device that can play back pictures while varying the viewpoint in real time is realized.
摘要翻译：传统的编码方法存在的问题是，对于逐帧反向重放，数据必须在向前方向一次解码，因此必须处理更大量的数据，并且需要更大量的存储器。通过重新编码比特流中的帧的前向预测图像和后向预测图像，可以容易地逐帧地反向地重放比特流。通过使用这种多视点视频编码方法，实现了可以实时改变视点的同时播放图像的装置。

摘要： An image encoding device and corresponding decoding device are disclosed for achieving a high rate of compression. The encoding device includes an image conversion module that converts the direction of the images using right-left symmetry mode convention or up-down symmetry mode conversion. Encoding modules are used to encode both the unconverted and converted images. A mode selector module compares the quantity of codes in the encoded unconverted images and the quantity of codes in the encoded converted images, and selects codes that are smaller in the quantity of codes for output.

摘要： File management method having first and second processing modes for storing file type information for discrimination between first and second processing modes in recording medium as file management information associated with file for file management. In first processing mode, when data in the form of file is written on a recording medium and a write error occurs, replacement processing to another write area is performed to write the data in another area. In second processing mode, when write error occurs, the replacement processing to other write area is not performed to write the data. Method includes reading file type information associated with a file to be processed from recording medium, converting the file type from file type indicative of first processing mode to file type indicative of second processing mode, and writing the file type after conversion in recording medium as file management information associated with the file to be processed.
