Abstract: A management method, a computer performs an acquisition of video data from a monitoring terminal, an acquisition of a first event and a detection time of the first event from the video data; and a display of the detection time of the first event and an icon corresponding to a type of the first event, in a form according to the importance of the first event, on a display devise.

Abstract: A management device that includes an instruction unit that acquires metadata of video data of an area to be monitored generated by a monitoring terminal that detects an event from the video data, outputs, in response to an acquisition of metadata including information about the event, an analysis instruction for the video data of the area to be monitored imaged in a time zone including a time of detection of the event to a video analysis device that detects the event from the video data, and acquires an analysis result including information about the event detected from the video data by an analysis by the video analysis device, and an estimation unit that estimates a case event that has occurred in the area to be monitored based on the event detected by the monitoring terminal and the event detected by the video analysis device.

Abstract: The present invention reduces the amount of processing related to the analysis of video data. A detection time determination unit (11) determines a detection time for detecting a second event before or after a first event in time series from the video data on the basis of a time when the first event is detected from the video data, and an event detection unit (12) detects the second event from the video data in the detection time.

Abstract: An appropriate response to an event is recommended to a monitoring person. An event detection unit (12) detects an event based on video data, and an alert unit (13) issues a first alert when a first event is detected, and issues a second alert that is distinguished from the first alert when a second event relating to the first event is further detected in addition to the first event.

Abstract: A content distribution system comprises a script generation unit. The script generation unit determines a distribution request time, which is the time when the terminal issues a request to a server for the distribution of the items of content, and a reproduction start time, which is the time when the terminal starts reproduction of the content included in the content list, at which it is anticipated, on the basis of a content list which is a list of content to be reproduced at a terminal and on the basis of the distribution state of the content, that the content included in the content list can be reproduced at the terminal without interruption. The script generation unit then generates a script which describes the distribution request time and the reproduction start time that have been determined, and transmits the generated script to the terminal.

Abstract: After an input image signal (2000) of a smaller resolution is encoded by an encoder (20), an input image signal (1000) of a greater resolution is subjected to motion compensation processing by a motion compensation unit (102) according to motion information (1998), thereby generating a prediction error signal (1001). Simultaneously with this, an enlarged decoded image (2003) obtained by enlarging the decoded image (2002) obtained by an encoder (20) is subjected to motion compensation processing by a motion compensation unit (103) according to the motion information (1998), thereby generating a prediction error signal (2005). By referencing the prediction error signal (2005), the prediction error signal (1001) is subjected to conversion encoding, quantization, and entropy encoding.

Abstract: In a time/space-division filtering, a moving image signal in a certain resolution-hierarchy, for which time hierarchizing is performed, is divided into a time low-band signal and a time high-band signal. A moving image signal, which has the moving image signal corresponding to the time high-band signal reconstructed by employing the time low-band signal and the time high-band signal, is generated. A reduced image signal having the moving image signal reduction-processed is generated. A high-band generating process by space hierarchizing is performed for the time high-band signal, thereby to generate a time high-band/space high-band signal. The time low-band signal, the reduced image signal, and the time high-band/space high-band signal are assumed to be a division result respectively.

Abstract: A lower hierarchical decoder (100) decodes lower hierarchical data (1001), and creates a prediction error signal (1004). A switch (107) accepts a decode hierarchical instruction signal (1100) indicating which of the upper and lower hierarchies a hierarchical image decoding device decodes, and switches a prediction decode processing. In case the lower hierarchy is decoded, the switch (107) inputs a lower decoded signal (1009) as an output to a prediction decode unit (105), and creates a lower hierarchical decoded image (1008). In case the upper hierarchy is outputted, the switch (107) inputs the lower decoded signal (1009) to a pseudo prediction decode unit (106), and creates a lower hierarchical decoded image (1009). An upper hierarchical decoder (200) inputs upper image data (2001), and creates an upper hierarchical decoded image (2008) with reference to the lower hierarchical decoded image (1009).
