Abstract:
According to one embodiment, an IP broadcast system includes a transmitting side and a receiving side connected to the transmitting side through a broadcast network on an IP network. The transmitting side includes a multiplexer which generates a standardized multiplex frame including at least a header field and an information field by multiplexing a plurality of RTP packets. The receiving side includes a buffer which temporarily holds the multiplex frame from the broadcast network and a program reproducer which retrieves and analyzes the multiplex frame from the buffer, extracts a reproduction clock shared by a plurality of programs, demultiplexes a plurality of TSs for each program from the multiplex frame, and based on the reproduction clock, reproduces the programs from each TS.

Abstract:
It is assumed that a reception processing unit receives a broadcast program in accordance with tuning based on the user's specification. In this state, a non-viewable state detection processing unit monitors occurrence of a non-viewable state from an acquisition state of reception data. When the non-viewable state occurs due to a certain factor, a non-viewable state accumulation unit accumulates information on the non-viewable state. When the factor of a viewing interruption is solved and a user makes a request for service provision, the processing unit connects to a distribution apparatus to report content of the non-viewable state, and receives distribution of a relevant content, thereby the processing unit becomes able to recontinue interrupted broadcast content.
Abstract:
To realize efficient processing regarding accesses to files. A remote controlling processing apparatus 14 of a file sharing system 10 is connected via a network 15 to a controlled processing apparatus 12 including a file storage part 17 in which a plurality of files 1, 2, 3 . . . are stored. Further, the remote controlling processing apparatus 14 includes: an access request generating part 19 generating access requests to the files 1, 2, 3 . . . in the file storage part 17; an access request storage part 22 in which the plural generated access requests are sequentially stored; and an access request notifying part 25 integrating plural ones of the access requests in the access request storage part 22 based on a storage status in the access request storage part 22 to notify the integrated access request to the controlled processing apparatus 12.

Abstract:
It is provided a recorder apparatus in which a user can use simply and efficiently plural functions which can be performed simultaneously. According to an embodiment of the invention, a recorder apparatus has a display, an input section for a video being inputted, a random access recording medium for recording the video, an output section for outputting the video recorded in the recording medium, a multitask control section, a display control section and a reception section for receiving an specification of the tab and the direction of the video for a processing target for the selected function. The multitask control section performs plural functions in parallel simultaneously which plural functions includes a function for recording the inputted video in the recording medium. The display control section displays tabs assigned to the plural functions respectively and processing situation of the function selected by specifying the tab on the display.

Abstract:
A video recorder which can maintain compatibility with a video recorder which uses magnetic tape as a recording medium and manage recorded videos easily is provided. The video recorder has a random access recording medium, a video management part, a control part and a video playback part. The video management part records information showing a group, and information showing record order of the video material in the specified group in the recording medium as the management information. A control part records the video data in the recording medium, reads out the management information from the recording medium, and read out the video data in the record order according to the information showing the record order. And the video playback part plays back the video data read out from the recording medium.
