Moving image coding apparatus, moving image decoding apparatus, moving image coding method, and moving image decoding method

TL;DR: In this article, the authors proposed a method for signaling image information and a decoding method using same, which consists of a step of performing inter-prediction for a current picture; and a further step of signaling information including the result of said interprediction and reference picture information indicating reference pictures usable in said inter prediction.

TL;DR: In this article, a gradual decoder refresh (GDR) of a picture is enabled, and the coding process, systems, methods, and apparatus may code information that indicates whether one or more slices belong to a foreground region of the picture.

TL;DR: In this article, a decoding method for decoding video data was proposed, where the first picture is associated with a first picture of the plurality of pictures, and when none of the pictures that follow the first image has a picture order count greater than the POC value of the recovery point picture.

TL;DR: In this paper, a method performed by an encoder for encoding a representation of a video stream of multiple pictures is provided, and information is sent to a decoder indicating if the current picture is not used as a reference picture by any picture belonging to the same or lower layer.

TL;DR: In this article, the maximum value of a reference index and a command also for field encoding in frame/field switching encoding in a macro block unit is utilized to appropriately and effectively utilize the maximum values of the reference index.

TL;DR: In this article, the problem of extracting coding data with intra-picture other than the IDR picture defined as the editing point is addressed, where the coding data are inputted from an HDD101 to a coding data extracting unit 102 and a reordering information generating unit 104; and the coding coding data extraction unit 102 extracts the encoding data after the coding point from the encoding, and outputs the same data to a header information changing unit 103 in accordance with designation by external users or the like.

TL;DR: In this paper, the problem of using an initializing unit as a return point in predictive coding between a plurality of pictures is solved by using the return point as a short unit in the decoding apparatus.

TL;DR: In this article, a moving image playback apparatus has a structure wherein a decoder is initialized when a CPU first detects an SPS-equipped I-picture in playback of a video stream of an HD DVD, and the decoder decodes the video stream.
