The objective of the present invention is to manage reference movies using an index file, without causing the user to be perplexed. The reference movies are generated because of, for instance, the upper limit of the file size. The index file manages sets of information regarding the files being managed. Examples of these sets of information are information for determining whether or not a file is presented to the user, information for determining whether or not a file is original, and information indicating whether or not nondestructive editing has been done. Based on such information, the erasure, displaying a list, and so on are carried out. Thus, it is possible to manage the reference movies using the index file, without causing the user to be perplexed.

Data recording method, data erasure method, data display method, storage device, storage medium, and program

To provide a video data reproducing apparatus or the like, which includes: a flag readerfor reading out a flag that designates a playback style during special playback, from video data; decodersandfor decoding two sets of video data; a synthesizerfor combining the decoded videos to output the result; and a managerfor controlling the operations of decodersand synthesizerin accordance with the flag value, and which manages the playback style in the special playback during picture-in-picture playing in accordance with the flag value, to thereby realize the playback style of the picture-in-picture video during the special playback that reflects the distributor's intention.

Video data reproducing apparatus, video data generating apparatus and recording medium

The invention provides data for display on the display area for a child frame when the child frame is synthesized and displayed on the parent frame in picture-in-picture playback in order to give the displayed area of the child frame in conformity with the video content in the parent frame, as well as providing a video display apparatus etc. for displaying the child frame at an appropriate displayed position using the data for display. A video display apparatusincludes: decodersandfor decoding two sets of video data; a synthesizerfor synthesizing the decoded videos to output; an input unitfor commanding display/non-display of the child frame; a processing controllerfor controlling the operations of decodersandin accordance with the command; and a position designatorwhich receives the command and the data for display and time information and designates the displayed position of the child frame to the synthesizer. The position designatordetermines the displayed position of the child-frame video in accordance with displayable time information of the child-frame video and information on the displayed area or displayable area depending on time, included in the data for display.

Video synthesizing apparatus and program

A content distribution system that is supplied with power from a plurality of power sources having different environmental loads and that distributes content to a content playback apparatus connected via a communication circuit, the content distribution system distributing content with respect to a content distribution request from the content playback apparatus with a service quality that is determined so as to suppress the environmental load by the power supplied from the plurality of power sources to a predetermined environmental load.

Content distribution system, content distribution apparatus, content distribution method, content distribution program, and content playback apparatus

A contents reproduction device can concurrently switch a video image and a graphics image from 2D to 3D. A contents reproduction device includes a program execution unit that outputs a graphics image used for 2D to a left graphics plane and outputs a graphics image used for 3D to left and right graphics planes; an AV reproduction unit outputs a video image used for 2D to the left video plane and outputs a video image used for 3D to the left and right video planes; and a switch unit outputs a first synthesized image of images stored at the left video plane and the left graphics plane at the 2D reproduction time and switches to output a second synthesized image of images stored at the right video plane and the right graphics plane and the first synthesized image at the 3D reproduction time.

Content reproducing apparatus and recording medium for switching graphics and video images from 2D to 3D

The AV data reproducing apparatus includes: (i) a reading section for reading out, from a recording medium, additional function information indicating an additional function correlated with a manipulation input; and (ii) an additional function program executing section for executing the additional function in response to the manipulation input. With this, an operation unique to the content can be carried out by executing the additional function (additional function program) indicated by the additional function information stored in the recording medium together with the AV data. This makes it possible for the AV data reproducing apparatus to carry out an operation other than an operation intrinsically corresponding to a key.

The invention provides data for display on the display area for a child frame when the child frame is synthesized and displayed on the parent frame in picture-in-picture playback in order to give the displayed area of the child frame in conformity with the video content in the parent frame, as well as providing a video display apparatus etc. for displaying the child frame at an appropriate displayed position using the data for display. A video display apparatusincludes: decodersandfor decoding two sets of video data; a synthesizerfor synthesizing the decoded videos to output; an input unitfor commanding display/non-display of the child frame; a processing controllerfor controlling the operations of decodersandin accordance with the command; and a position designatorwhich receives the command and the data for display, and time information and designates the displayed position of the child frame to the synthesizer. The position designatordetermines the displayed position of the child-frame video in accordance with displayable time information of the child-frame video and information on the displayed area or displayable area depending on time, included in the data for display.

A video disk player includes (i) a disk reading section for reading out video data, a program, synchronization timing information from an optical disk; (ii) a clock for generating a clock signal; (iii) a decoder for converting, in accordance with the clock signal, the video data into decompressed video data for reproduction output; (iv) a video reproducing section including a synchronization control section for transmitting, in accordance with the clock signal, a synchronization control signal to the program executing section at a timing specified by a field timing contained in the synchronization timing information, and (v) a program executing section for executing a program in accordance with the synchronization control signal received from the synchronization control section. This makes it possible to efficiently execute the program in synchronization with reproduction of AV data or the like.

Video data reproducing apparatus and method utilizing acquired data structure including video data and related reproduction information, non-transitory recording medium containing the data structure and non-transitory recording medium storing control program for causing computer to operate as reproducing apparatus
