摘要:
A reproduction device (100) includes: a resume information generation unit (121) which generates first resume information (R1) indicating a reproduction stop operation position and second resume information (R2) indicating a reproduction position at one or more of the following moments: upon switching of the reproduction operation type, upon switching of the reproduction information title and/or the chapter, and at regularly spaced reproduction time intervals; a resume information acquisition unit (123) which acquires the first resume information (R1); and a resume information automatic acquisition means (124) which acquires the second resume information (R2). Upon resume reproduction, the reproduction stop operation position indicated by the first resume information (R1) or the reproduction position indicated by the second resume information (R2) is selected, so that the reproduction is resumed at the selected position.

摘要:
During video audio recording, key frames are temporarily stored from the video audio stream to be recorded, and metadata is later generated from the temporarily stored key frames. Even if a CPU or system configuration of a relatively low performance is used, metadata generation can be carried out in parallel with the video recording operation.

A file transfer method and a file transfer system are provided for making it possible to minimize aggregate waiting time of the whole users for data transfer using a multicast protocol. In the file transfer method of transferring a plurality of program files from a recorder storing a plurality of program files via a network to a plurality of mobile terminals using a multicast protocol, the recorder determines order of transfers of the plurality of program files for the purpose of transferring the plurality of program files in order of digital data files, which is the ascending order of file size of the plurality of program files (step S102), the recorder transfers the plurality of program files on the basis of the order of transfers (steps S104-S109), and the plurality of mobile terminals selectively receives the plurality of program files (steps S204-S207), thereby reducing aggregate waiting time that is a sum total of transfer time of the whole users.

An apparatus and method for programming the recording of broadcast programs, for programming recording by setting the recording start time and the recording end time of a given program in the broadcast program information is provided, wherein the apparatus and method for programming the recording of broadcast programs, delays the recording end time of programmed broadcast program, when a broadcast program is present in which an extension keyword is detected by searching electronic program guide information acquired regarding broadcast programs to be programmed, and electronic program guide information acquired regarding programs scheduled to be broadcast on the same channel and the same date as and prior to the programmed broadcast program, for predetermined extension keywords indicating program extension or delay.

A video/audio playback apparatus that can continue playback even if the external storage means are disconnected during playback, includes a virtual file system section 24 for merging the video/audio information and playback control information of the optical disc 12 with the video/audio information and playback control information of the local storage 7 to configure a virtual file system; a pseudo file system generator 2a for generating a pseudo file system 4a; a RAM 4 for storing the generated pseudo file system 4a; a disconnection detector 2b for detecting disconnection of the local storage 7 from the connecting section 15; and a playback manager 21 for causing the virtual file system section 24 to merge the video/audio information and the playback control information of the optical disc 12 with the information of the pseudo file system 4a immediately after the disconnection is detected, thereby newly configuring the virtual file system.
摘要:
I-frames are extracted from a normal play stream in an extract section (12), coding parameters and control parameters, such as VBV delay, related to a decoder buffer are modified for trick play in an I-frame picture data conversion processor (15), repeat pictures that display the same image content as the I-frames are generated and added following the I-frames in a repeat picture adder (16), and the transfer rate is controlled in a picture data size controller (17). This solves the problem that when trick play is executed between a server and a terminal on a network, if only I-frames are used the necessary network bandwidth may increase, a buffer may fail in the decoder that reproduces the trick play stream, and the reproduced video image may be disrupted.
摘要:
There are provided steps of extracting parts of two image data as areas for analysis (S702, S704) and an image difference detection step (S707) of detecting an image difference between the two images, based on a difference in image characteristic values of the regions for analysis; the regions for analysis in the two image data have identical size. If no image difference is detected, the region extraction steps may expand the regions for analysis (S707) by adding part or all of the image data that was not previously included in the regions for analysis (S704). Scene changes can be done rapidly in images and video.

There are provided with a video recording apparatus and a scene change extraction method, by which a scene change can be extracted from a video while recording the video. The video recording apparatus 100 includes an encoder 101 for encoding video data PIN, an HDD 105 for storing an encoded stream outputted from the encoder 101, a stream controller 103 for transferring the encoded stream outputted from the encoder 101 to the HDD 105, a scene change extractor 110 for decoding the encoded stream outputted from the encoder 101 and extracting a scene change in the decoded video data, and a recording controller 102 for receiving an encoding-completion notification IEN on a unit-of-encoding basis of the encoded stream from the encoder 101 and outputting a scene change extraction instruction CSC to the scene change extractor 110.
