`ABSTRACT
`
`An information editing apparatus is provided which can pre
`vent a thumbnail image, which shows the contents of
`recorded information recorded on an information recording
`medium, from being accidentally changed by a misoperation
`of the user.
`
`The information editing apparatus includes a deciding device
`8 for deciding whether a thumbnail image can be changed or
`not based on change permission information, which indicates
`whether a change can be made on the thumbnail image show
`ing the contents of recorded information recorded on a
`recording medium 1. When the deciding device 8 decides that
`a change is not permitted, a change of the thumbnail image is
`prohibited.

`With this configuration, according to the invention of claim
`1, when the deciding device decides that a change is not
`permitted based on the change permission information indi
`cating whether the thumbnail image can be changed or not, a
`change of the thumbnail image is prohibited. Thus, it is pos
`sible to prevent an accidental change of the thumbnail image
`which shows the contents of the recorded information. Con
`sequently, it is possible to protect thumbnail images and
`recorded information set by a contents holder and protect
`thumbnail images set by the user.

`editing apparatus of claim 1, the invention of claim 2 is
`characterized by comprising a generating circuit which gen
`erates a display signal for displaying a warning indicating that
`the thumbnail image cannot be changed when the deciding
`device decides that a change is not permitted.
`With this configuration, according to the invention of claim
`2, when the deciding device decides that a change is not
`permitted, a warning is displayed to indicate that the thumb
`nail image cannot be changed. Thus, it is possible to enable
`the user to clearly recognize that the thumbnail image cannot
`be changed.
`In order to solve the problem, according to the information
`editing apparatus of claim 1, the invention of claim 3 is
`characterized by comprising a changing device for changing
`the thumbnail image when the deciding device decides that a
`change is permitted.
`With this configuration, according to the invention of claim
`3, when the deciding device decides that a change is permit
`ted, the thumbnail image is changed. Thus, the user can select
`whether a thumbnail image should be protected or not,
`thereby facilitating the setting of the thumbnail image for the
`USC.
`In order to solve the problem, the invention of claim 4 is an
`information editing method for editing a reproduced form of
`recorded information which includes at least image informa
`tion and is recorded on a recording medium, comprising a
`deciding process for deciding whether a thumbnail image can
`be changed or not based on change permission information
`indicating whether a change can be made on the thumbnail
`image showing the contents of the recorded information
`recorded on the recording medium, wherein when the decid
`ing process decides that a change is not permitted, a change of
`the thumbnail image is prohibited.
`With this configuration, according to the invention of claim
`4, when the deciding process decides that a change is not
`permitted based on the change permission information indi
`cating whether the thumbnail image can be changed or not, a
`change of the thumbnail image is prohibited. Thus, it is pos
`sible to prevent an accidental change of the thumbnail image
`which shows the contents of the recorded information. Con
`sequently, it is possible to protect thumbnail images and
`recorded information set by a contents holder and protect
`thumbnail images set by the user.
`In order to solve the problem, according to the information
`editing method of claim 4, the invention of claim 5 is charac
`terized by comprising a generating process which generates a
`display signal for displaying a warning indicating that the
`thumbnail image cannot be changed when the deciding
`device decides that a change is not permitted.
`With this configuration, according to the invention of claim
`5, when the deciding process decides that a change is not
`permitted, a warning is displayed to indicate that a thumbnail
`image cannot be changed. Thus, it is possible to enable the
`user to clearly recognize that the thumbnail image cannot be
`changed.
`
`A conventional information editing apparatus is disclosed
`in Japanese Patent Laid-Open No. 2000-353375. The infor
`mation editing apparatus is used to edit a reproduced form of
`recorded information which includes one or more images and
`is recorded on an optical disk. In the apparatus, a part of the
`recorded information that includes one or more images is
`selected from the recorded information, the timing of the
`reproduction of the selected part is specified, the image
`included in the part is extracted as a representative image of
`the part, and the specified timing of reproduction and the
`extracted representative image are recorded on the optical
`disk as a play list separately from the recorded information.
`That is, in the format of the conventional information edit
`ing apparatus, information indicating the reproduction posi
`tion of recorded information is recorded on the optical disk
`serving as a recording medium and a thumbnail image is
`generated from the recorded information, the thumbnail
`image showing what is in the recorded information (herein
`after also referred to as contents) on the optical disk.
`In the method in which a thumbnail image of the contents
`recorded on the optical disk is specified in the conventional
`information editing apparatus, it is possible to reset the
`thumbnail image, whereas there is no device indicating the
`prohibition of resetting. Therefore, in the conventional infor
`mation editing apparatus, a thumbnail image set by the user
`and a contents holder may be accidentally changed by a
`misoperation of the user.
`The present invention is devised in view of the circum
`stances. An object of the present invention is to provide an
`information editing apparatus capable of preventing an acci
`dental change of a thumbnail image which shows the contents
`of recorded information, an information editing method, an
`information editing program, and an information recording
`medium.

`BEST MODE FOR CARRYING OUT THE
`INVENTION
`
`Preferred embodiments of the present invention will be
`described below in accordance with the accompanying draw
`ings.
`In the following embodiments, an information editing
`apparatus of the present invention is applied to an information
`recording apparatus which can record, on a portable hard
`disk. AV (Audio Visual) information (including music infor
`mation or image information) distributed via a network Such
`as the Internet, and edit the recorded AV information, the hard
`disk being processed for copyright protection.

`In the following explanation, the AV information is distrib
`uted according to the transport stream standard of MPEG
`(Moving Picture Experts Group)2, which is a known standard
`of a moving image compression technique.
`
`6
`Further, the following thumbnail images are defined: a
`vendor definition thumbnail image which is set in advance by
`the vendor and distributed with AV information, and a user
`definition thumbnail image which is additionally set by the
`user after distributed AV information is recorded on the hard
`disk.
`Third, in the recording formats below, a concept program
`set' is used as a set including two or more user definition
`program lists or vendor definition program lists created based
`on a reproduced form desired by the user (to be specific, the
`reproducing order specified by the user for each piece of AV
`information). The following program sets are defined: an
`initial program set used for reproducing, in the original
`recording order, AV information (program) first recorded on
`the hard disk (a program list included in the initial program set
`is the vendor definition program list), and a user definition
`program set including the user definition program list.
`Fourth, in the recording formats below, a concept “index'
`is used as a kind of the instruction information. That is, the
`index is instruction information for specifying one program
`or a part of the program to make a distinction from other
`programs or other parts, and the index is provided for
`enabling the user to facilitate handling of AV information.
`The following indexes are defined: a vendor definition index
`which is set in advance by the vendor before distribution, and
`a user definition index which is additionally set by the user
`after distributed AV information is recorded on the hard disk.
`The vendor definition index is distributed as an index file
`along with AV information, whereas the user definition index
`is represented as the program list.
`The logical recording formats of the present embodiment
`will be discussed below based on the various concepts.
`As shown in FIG. 1, on a hard disk 1 where necessary AV
`information has been recorded, the following information is
`recorded: management information MI which is management
`information on an overall program recorded on the hard disk
`1 and is first referred to in the reproduction of recorded AV
`information, initial program set information DPSI which is
`management information on the initial program set, vendor
`definition thumbnail image information DFTN in which
`image information corresponding to the vendor definition
`thumbnail image is identified by the name of the image infor
`mation, user definition program set management information
`UDPM which is management information on the user defini
`tion program set, user definition thumbnail image informa
`tion UDTN in which image information corresponding to the
`user definition thumbnail image is identified by the name of
`the image information, program information PIF which is
`management information corresponding to the programs, AV
`stream information AVD which is an entity of AV information
`distributed and recorded on the hard disk 1, access unit ref
`erence information ACU which includes, for each access unit,
`address information and information indicating a total
`amount of information of one I picture (Intra-coded Picture)
`in one access unit, the address information indicating the
`recording position of the I picture on the hard disk 1 in one
`access unit, which is constituted of image information corre
`sponding to the I picture included in the AV information,
`license management information CIF for managing a license
`status of recorded AV information, the vendor definition
`index IDX, auxiliary thumbnail image information TMN cor
`responding to an auxiliary image which is used as a thumbnail
`image but is neither the vendor definition thumbnail image
`nor the user definition thumbnail image, and user definition
`program set information UDIF1 to UDIFn serving as man
`agement information on the user definition program sets

`
`(I) EMBODIMENT OF A RECORDING FORMAT
`First, prior to a specific explanation about the information
`recording apparatus of the present embodiment, referring to
`FIGS. 1 to 7, the following will describe the outline of logical
`recording formats which are used when the information
`recording apparatus records the AV information on the hard
`disk. FIGS. 1 to 7 schematically show the recording formats
`in a hierarchical manner. The AV information has been
`recorded on the hard disk in the recording format.
`The recording formats shown in FIGS. 1 to 7 are logical
`recording formats used for recording the AV information of
`the present embodiment on the hard disk. As to the physical
`recording format used for recording, a known physical format
`for the hard disk is used as it is.
`First, the following will describe the outline of various
`concepts which are used in the recording formats to effi
`ciently manage the contents and the recording format of the
`recorded AV information.
`First, in the recording formats below, a concept "program'
`is used as a unit for handling recorded AV information. That
`is, a program represents one piece of AV information continu
`ously recorded on the hard disk.
`When distributed AV information is analog information,
`for example, when one television program is continuously
`30
`recorded, the television program acts as a “program. When
`only a part of the program is continuously recorded, only the
`continuously recorded part acts as a “program. When a plu
`rality of television programs are continuously recorded at
`same time, the continuously recorded television programs act
`as one “program.” Meanwhile, when the AV information is
`digital information, for example, when the AV information is
`distributed via BS (Broadcast Satellite) digital broadcasting,
`one event of BS digital broadcasting is defined as a “pro
`gram.
`Second, in the recording formats below, a concept "pro
`gram list’ is used to enable the user (user who watches
`recorded AV information) to freely edit recorded AV infor
`mation and logically create a new program. That is, the pro
`gram list is a set of pieces of instruction information (gener
`ally also referred to as pointers) used for specifying one
`program or a part of the program to make a distinction from
`other programs or other parts. A representative image (here
`inafter referred to as a thumbnail image), which represents the
`contents of AV information (image information) included in
`the program list, can be defined for each program list.
`Therefore, for example, when the user performs edits so as
`to successively reproduce a part of one recorded program and
`a part of another recorded program in this order, the user
`combines instruction information indicating the part of the
`one program and instruction information indicating the part
`of the another program so as to reproduce the instruction
`information in this order, so that one program list is created.
`With the concept of the program list, it is possible to repro
`duce AV information in a reproduced form desired by the user
`without changing the original recording order and so on of the
`AV information having been recorded on the hard disk.
`The following program lists are defined: a program list set
`by the user who refers to recorded AV information in the
`above manner (user definition program list), and a program
`65
`list set in advance by a provider (vendor) who distributes AV
`information to be recorded (vendor definition program list).

`which are defined after AV information is recorded on the
`hard disk 1 (FIG. 1 has n sets of user definition program sets).
`As shown in FIG. 1, the management information MI is
`constituted of hard disk identification information MID (12
`bytes) for identifying the hard disk 1 from other hard disks,
`version information VRN (2 bytes) indicating the version of
`the hard disk 1, character type information CHS (2 bytes)
`indicating a character type (attribute) included in recorded AV
`information, name information REP (128 bytes) indicating a
`name when the hard disk 1 has a name, a last access program
`set number RSM which is the number of the last program set
`reproduced at the completion of the reproduction of AV infor
`mation recorded on the hard disk 1, name information DPP
`describing a file name of the initial program set information
`DPSI (i.e., a so-called path name which specifically indicates
`the name “initial program set information DPSI), and name
`information UMP describing a file name of the user program
`set management information UDPM (similarly referred to as
`a path name which specifically indicates the name “user defi
`nition program set management information UDPM).
`Referring to FIG. 2, the detailed configuration of the initial
`program set information DPSI will be described below.
`As shown in FIG. 2, the initial program set information
`DPSI includes ini
