摘要： PROBLEM TO BE SOLVED: To improve the performance of detecting an editing point of an edited cinema video image by highly accurately detecting combing noise, and to contribute to improvement of image quality by performing a correction to an original video combination or a prompt release from a film mode. SOLUTION: The combing noise detecting section 20 calculates a differential of input images on the basis of combination information outputted as a detection result of a film mode detecting section 12. In a case where a fixed-level or more luminance change (luminance) is continued for (m) Lines or more, it is detected as combing noise and the detection result of the film mode detecting section 12 is controlled so as to indicate a "field mode non-detected state".

摘要： PROBLEM TO BE SOLVED: To provide a stable video image by preventing quality deterioration caused by erroneous interpolation even when a non-video region is included in a video image subjected to image interpolation. SOLUTION: A feature value calculation unit 103 calculates the feature value of an entire picture, and a feature value calculation unit 102 calculates a feature value only in a picture region designated by a designation information unit 101. An interpolation determination control unit 104 outputs interpolation ON when the two feature values are coincident with each other, but outputs interpolation OFF when not coincident. A picture center interpolation unit 111 uses a motion vector from a motion vector search unit 105 to generate an interpolation image within the picture region. A picture end interpolation unit 112 performs interpolation processing upon a picture end during interpolation ON but stops the interpolation processing upon the picture end during interpolation OFF. Consequently, during interpolation ON, an interpolation frame for interpolating the entire picture is output and during interpolation OFF, an interpolation frame for interpolating only the designated picture region is output.

摘要翻译：要解决的问题：即使当非视频区域被包括在经过图像插值的视频图像中时，通过防止由错误插值引起的质量恶化来提供稳定的视频图像。特征值计算单元103计算整个图像的特征值，特征值计算单元102仅在由指定信息单元101指定的图像区域中计算特征值。插值确定控制单元104 当两个特征值彼此一致时，输出内插ON，但在不一致时输出插补OFF。图像中心插值单元111使用来自运动矢量搜索单元105的运动矢量来生成图像区域内的插值图像。图像结束插值单元112在内插ON期间对图像结束进行插值处理，但是在插值关闭期间停止针对图像结束的内插处理。因此，在内插ON期间，输出用于内插全部图像的内插帧，并且在插值关闭期间，仅输出指定图像区域的内插帧被输出。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an encoding method for realizing high encoding efficiency and high quality encoding even if a picture is present in which a scene change occurs inside an interlace frame.
SOLUTION: In a moving image encoding method in which a frame of an interlace image input signal is defined as a picture and a picture is included to predict and encode said picture from both a forward picture of temporal past and a backward picture of future for the unit of macro block, when performing encoding by prediction from both the pictures, inter-field motion prediction is performed for the unit of a field resulting from dividing the pictures into odd or even pixel scans of the frame for the unit of the macro block. As a prediction mode, it is selectively switched for each picture whether one field uses prediction from a motion vector of the forward field and whether another field uses prediction from a motion vector in the backward field. A predictive image is generated in accordance with the selected prediction mode, and the generated predictive image is used to encode the input signal.

摘要： PROBLEM TO BE SOLVED: To simultaneously solve the problems of traffic increase and correction delay regarding a packet retransmission control technology in packet missing during multicast communication. SOLUTION: When packet missing occurs during transfer from a terminal C to a terminal A, a retransmission request is transmitted from the terminal A to the terminal C. In the retransmission request, an address of a terminal B is transmitted as a list of simultaneous transmission destinations. Packet missing information is transferred from the terminal A to a downstream side in a group. A packet is retransmitted from the terminal C to the terminal A. The terminal A multicasts the received retransmission packet. The packet is retransmitted from the terminal C to the terminal B. The terminal B fills a place of missing with the received retransmission packet as a normal transfer packet and multicasts the packet thereafter. In a group 3, transfer of missing information of transfer data "2" is not required, thereby solving traffic increase and correction delay. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To avoid a situation such that route correction cannot be performed when terminals are grouped in a streaming delivery technique for connecting a plurality of terminals in a peer-to-peer manner and performing real-time data delivery by relay transfer of data.
SOLUTION: In a network group management system, increase/decrease management and connection management of each terminal in an own group are performed by executing comparison determination processing for determining a relation among a delivery data band of data real-time delivered in the own group, an inflow data band to the own group and an outflow data band from the own group. The comparison determination processing is, for example, processing for comparing the sum of the sum of terminal-possessed transfer bands and the inflow data band from other groups to the own group with the sum of a value obtained by multiplying the delivery data band in the own group by the number of terminal groups in the own group, the outflow data band from the own group and a predetermined determination margin.

摘要： PROBLEM TO BE SOLVED: To achieve a high quality image by reducing the occurrence of combing noise in a synthesized image having an inserted image of a different frame frequency.
SOLUTION: A feature amount of a screen in an input interlace-scanned video signal is extracted, and a film mode is detected on a screen-by-screen basis from the feature amount extracted by a means for extracting the feature amount of the screen. When a feature amount not being the file mode is detected from data of a line-by-line local area, the feature amount is not detected as the film mode. The decision to be a synthesized image is made by deciding the presence or absence of motion through a threshold decision of an interframe difference, and in case that the motion is present, with regard to consecutive three fields, obtaining first and second sum of absolute interfield differences by adding the absolute differences between the consecutive two fields for a line-by-line local area. A quotient between the first sum of the absolute interfield differences and the second sum of the absolute interfield differences is obtained, and when the quotient is 1, the video signal is judged as the synthesized image.
