Embodiment Construction
[0093] Next, embodiments of the present invention will be described. The relationship between the elements of the claims and the embodiments is as follows. The relationship means that specific examples supporting the invention set forth in the claims are described in the embodiments. Therefore, even if some specific examples are not described in the elements of the claims, it does not necessarily mean that the specific examples do not correspond to the elements of the claims. Conversely, even if specific examples are described as corresponding parts to elements of the claims in this section, it does not necessarily mean that these specific examples do not correspond to elements other than elements of the claims.
[0094] In this section, all aspects of the invention that do not necessarily correspond to the specific examples described in the embodiments of the invention are set forth in the claims. In other words, the descriptions in this section correspond to specific examp...

Abstract
A progressive-scanned picture is displayed without a loss of its vertical resolution. In a picture encoding apparatus 101, a determined result that represents whether an encoding target picture is an interlace-scanned picture or a progressive-scanned picture is set to a scanning flag. Information that represents a display system of a picture is set to display system designation information. Encoded data of which the picture, the scanning flag, and the display system designation information have been multiplexed are output. A picture decoding apparatus 102 recognizes a picture on the basis of the scanning flag and the display system designation information of the encoded data. When the picture is an interlace-scanned picture, the picture is interpolated with fields. As a result, a frame picture is generated and output. When the picture is a progressive-scanned picture, the picture is recognized as a frame picture and repetitively output the number of times corresponding to the display system designation information. The present invention may be applied when a picture is encoded and decoded on the basis of H.264 / AVC.
Description
technical field [0001] The present invention relates to a coding device, a coding method, a decoding device, a decoding method, a program, a program recording medium, a data recording medium, a data structure, and a reproducing device, and more particularly, relates to allowing, for example, progressive scan images to be displayed without degrading Its vertical resolution encoding device, encoding method, decoding device, decoding method, program, program recording medium, data recording medium, data structure and reproducing device. Background technique [0002] In recent years, processing digital data, compressing and decoding image signals through image redundancy for efficient information transmission and storage, and using orthogonal transforms based on, for example, the Moving Picture Experts Group (MPEG) standard such as discrete cosine transform and motion compensation Advanced image processing devices spread among broadcasting stations distributing information, as w...
