Provided is an information recording medium which achieves high speed conversion of a signal input from external from MPEG-TS to MPEG-PS complying with DVD standard. An apparatus and a method for recording information to the information recording medium are also provided. A constrained format which enables conversion from a first stream (for example, MPEG transport stream) to a second stream (for example, MPEG program stream) is provided. The constrained format defines that a first packet (for example, TS packet) is grouped and managed in multiplexing unit. The first one (AF#8) of complete audio frames in the multiplexing unit (402) is the first one of audio frames in a payload of a second packet (for example, PES packet) (413).

A method of presenting video frames of a video segment at a non-standard speed is provided. A frame count is set to an initial value. For each video frame that is to be presented, a time offset relative to a staring time within the video segment is generated. The time offset may be generated by multiplying the frame count by two values. The first value is a length of time for which each selected frame is to be presented to the user, and the second value is the presentation rate of the video segment relative to a normal presentation rate. A video frame within the video segment corresponding to the time offset within the video segment is selected and output for presentation. The frame count is then updated, and the process is repeated for the next frame to be presented.

A method and apparatus for receiving and recording a digital broadcast program and reproducing a recorded digital broadcast program with time-based trick play features. While recording a broadcast program on a storage medium, the apparatus creates an index file regarding random access points of the program. Receiving a request for a jump or trick play operation given in terms of time, the apparatus detects the time interval between each of the random access points based on the created file. Referring to the time interval, the apparatus determines the position to be reached by the jump and begins playback from the position or determines the number of access points to be skipped for the trick play and begins the requested trick play by skipping random access points by the number, thereby providing a user-friendly interface having time-based trick play features.

A recording and reproducing apparatus includes an information recording unit that generates reproduction range information indicating the range of image signals to be reproduced as moving picture and that records it on an optical disk. When representative images representing contents of the image signals recorded on the optical disk are displayed, the representative images are displayed as moving picture obtained by reproducing the image signals recorded on the optical disk based on the reproduction range information.

To provide means for editing a content data stream quickly.A data processor according to the present invention can edit a content that has been written on a medium. The content is stored in a file as a data stream including multiple packets of the same packet size. And a file system for accessing data on a cluster size basis has been established on the medium. The data processor includes: a receiving section, which receives an instruction on a partial deletion range including the beginning of the file; and a media control section for deleting data, the size of which is an integral number of times as large as the least common multiple of the cluster size and the packet size, from the beginning of the file within the partial deletion range.

A recording apparatus includes a first recording control unit configured to control recording of first management information so that fragments of the first management information and fragments of data are alternately placed, each fragment of the first management information being used to read the corresponding data fragment; a second recording control unit configured to control recording of second management information after all of the data has been recorded, the second management information being used to read all of the data; and a rewrite control unit configured to control rewrite of the first management information or the data after all of the data has been recorded so that any fragment of the first management information is not used to read the corresponding data fragment.

According to some embodiments, encoded information associated with an image is received at a decoder. The encoded information may be decoded at the decoder to generate full-sized first image pixels representing a full-sized version of the image. Moreover, the full-sized pixels may be scaled at the decoder to generate scaled image pixels representing a scaled version of the image.

A method of sharing data of a scalable video coding (SVC) file and the SVC file are provided. The SVC file includes: a scalable base track including at least one scalable layer entry each storing metadata of the at least one scalable layer; and at least one sub track generated based on the scalable base track, which includes identification information of the scalable layer that is a basis of generation of a sub track among the scalable layers and identification information of the scalable base track instead of the scalable layer entry. Accordingly, when an SVC coded content is stored as a file, it is possible to reduce a storage capacity by avoiding duplication of common data and to provide convenience when the stored content is reprocessed by allowing a relation of tracks correlated to one another to be represented.

An interactive communication apparatus is disclosed which has a video signal obtained by an image pickup device performing an image pickup activity and which has the obtained video signal sent to another apparatus through a communication section while causing a display section to display an image based on a video signal received from the other apparatus through the communication section. The apparatus includes: a pickup start and stop section; an indicator image storage section; a video switching section; and a control unit.

There is disclosed an image recording apparatus which automatically records location information that the user can easily understand in an image recording apparatus which records a sensed image and location information associated with the image sensing location of that image in association with each other. An image recording apparatus of this invention includes an area information reception unit for acquiring area information broadcasted by an external apparatus such as a wireless base station or the like, and automatically acquires information associated with an area where the image recording apparatus is located. The apparatus records a sensed image signal and area information in association with each other.
