Patent ID: 8650599

Claim:
An accumulation display device comprising: a reception unit that receives a currently broadcasted program content, index information associating a currently broadcasted program content with an index and specifying a scene of the program and trigger information including mode information for special reproduction of the program content and constituting metadata with the index information; an accumulation unit that accumulates the program content, the index information and the trigger information; a main display unit receiving and displaying the input of the program content received by the reception unit; a metadata interpretation unit that interprets the index information and the trigger information of the currently broadcasted or the accumulated program content and outputs mode information for special reproduction; an accumulated image processing unit connected with a mobile data terminal functioning as a sub reception and display unit, and extracting at least a part of the accumulated program content based on the mode information from the trigger information, restructures the program content extracted based on the mode information, and outputs the restructured program content to the mobile data terminal; and a mobile data terminal management unit managing information of the mobile data terminal to which the restructured program content should be outputted; the index information includes a program ID for identifying a program corresponding to the index information, an ID for identifying the index information, starttime data of the corresponding program, and finishtime data of the corresponding program; the mobile data terminal management unit manages information of the mobile data terminal and further, generates a metadata for a video operation menu including various operation commands for performing reproduction, replay reproduction, stop and so on corresponding to the mobile data terminal and transmits it to the mobile data terminal, and then realizes a video operation menu on the mobile data terminal; the accumulated image processing unit outputs, when the mobile data terminal management unit receives an operation command according to the metadata for the video operation menu from the mobile data terminal, the restructured program content to the mobile data terminal or stops the outputting operation according to the operation command; and the accumulated image processing unit, in the restructuring and outputting operation, further extracts at least a part of the program content from the index information based on contents of the trigger information, restructures the program content extracted based on the mode information, outputs the restructured program content to the mobile data terminal, and displays the restructured program content video operated on the mobile data terminal in a manner that the currently broadcasted original program content received by the reception unit is displayed in parallel on the main display unit.
