Description

Conversion equipment, content conversion method and computer readable recording medium storing program for performing

Technical field

The equipment consistent with exemplary embodiment and method relate to a kind of Content Transformation equipment, content conversion method and computer can Read record medium.

Background technology

With the development of electronic technology, the method for consumer video content becomes more and more diversified.In the past, user passes through By audiovisual (AV) device, (such as video cassette recorder (VTR), digital versatile disc (DVD) player, Blu-ray Disc (BD) are play Device) being connected with TV (TV) fetches the video content playing the video content receiving from broadcasting station or consumption.Recently, user Ke Tong Cross and use various device (such as personal computer (PC), smart phone and flat board PC) to carry out consumer video content.But, by mutually Networking or mobile network issue high-quality video content needs substantial amounts of time and cost.Therefore, for for by existing Video distribution means (that is, the broadcast that can use in the device of such as PC, smart phone and flat board PC, VTR tape, DVD and The demand of the method BD) creating video content increases.

Produce the content of the type that can be replicated and consume in PC, smart phone, flat board PC etc., when DVD or BD is existing Video content distribution means and when making content be recorded with digitization program, it is not necessary to Analog-digital Converter (ADC) and AV Compression, therefore, content can be replicated with low cost.But, typical digital document clone method has video content can not The problem being replicated perfectly.

Typical all bits to the information being identified as file for the digital document clone method replicate so that with original letter The same information of manner of breathing is present in destination.Generally, the example of typical digital document clone method can include that the file at PC is multiple Method processed.

Although being exactly the header cell in Blu-ray Disc in user's content, but present in actual disc be：Stream literary composition Part (video, audio frequency, sprite, text subtitle, BD Java code, image etc.), instruct the leading of method for playing stream Boat file and the file of metadata such as with the description with regard to CD.It is to say, title similarly is one for user Kind of data playitem, the real data for playing become part or all or multiple stream file of stream file.Therefore, Blu-ray Disc video content is corresponding to digital composite content, wherein, and digital composite content and stream file (such as video, audio frequency, son Picture, text subtitle, BD Java code and image) analyzed and broadcasting together with navigation file.Accordingly, it would be desirable to there is one Content Transformation become the form can play in PC, smart phone etc. be not only the Content Transformation side of the form that can be replicated Method.

Fig. 1 is the schematic diagram illustrating the relation being stored between the media file in Blu-ray Disc and structure of navigation information.This letter The video content that breath structure is stored in Blu-ray Disc.Digital composite content is stored in Blu-ray Disc, is used for playing this The method of content is determined according to as the movie objects of navigation data, BD-J object, playlist, playitems playitem etc..

Fig. 2 is the schematic diagram of catalogue and the file structure illustrating Blu-ray Disc.This catalogue is the angle from file.Herein, play Method means：Broadcasting scope in the file that will be played, this document, the playing sequence etc. of this broadcasting scope.BD-J pair As including player method and application, for example, screen play or control Blu-ray player.

The problem that accordingly, there exist is：When digital composite content is replicated without understanding such as according only to catalogue and the filename of Fig. 2 During navigation data shown in Fig. 1, only a part for former title can be replicated, or too many data can be replicated.Therefore, Need a kind of to understand the technology with output header for the navigational structure.

Additionally, only some streams being stored in one of Blu-ray Disc digital composite content are selected and replicate, described Stream can not be replicated by existing file copying method.Including multiple audio frequency and graphic subtitle in a video are being solved It is comprised in while multiplexing in Blu-ray Disc content.But, some in audio frequency are not lines and are probably for describing The audio frequency of film of director, and some in graphic subtitle also can be stored as not being the figure of the specific use of captions.Cause This, even if some in audio frequency and some in graphic subtitle are not needed and also replicate to being not selected property.Therefore, it is being combined In the case of digital content, need a kind of function allowing users to select and export only his/her desired content.

It is usually present multiple digital composite content (multiple title) in Blu-ray Disc.But, user is at not play menu title In the case of want to know that it is inconvenient for there is what title in an optical disc.Accordingly, it would be desirable to help user's classification and output spy Determine the single information (for example, configuration assistant user selects the information required for the menu of his/her desired content) of video.

In the case of changing content and export, a stream for each species is not output, but needs output Multiple streams.But, to once export multiple stream, it is necessary to change existing decoder architecture, therefore, have a problem in that manufacturer needs Will integrally correcting decoder chip.Accordingly, it is desirable to provide a kind of message structure and a kind of defeated for the performance in response to device The method going out only a kind of stream or multiple stream.

When the digital content that will be stored in Blu-ray Disc, be converted to can be in the device of PC, smart phone and flat board PC etc. During the form using, International Organization for standardization (ISO) base media file form (ISO BMFF) has been mainly used as finally The form of storage.It the reason that main use ISO BMFF form is that ISO BMFF is supported very long by information technology (IT) device A period of time, accordingly, there exist the many devices that can read this form.Additionally, MPEG-2 and MPEG-4 Video Decoder and MPEG4 advanced audio (AAC) audio decoders etc. are mainly supported in PC, smart phone and flat board etc., therefore have ISO The content of BMFF can be play in multiple devices.But, the digital composite content being stored in Blu-ray Disc is in the situation of video Under can support MPEG-2, MPEG-4 and VC-1, therefore can play in IT device and there is not big problem.But, in audio frequency feelings Under condition, digital composite content can support the high quality audio with AC-3, Lossless Compression (MLP) and Digital Theater System form, Digital composite content may not be play by typical IT device.Therefore, when to the digital composite content in Blu-ray Disc When changing and export, need a kind of function being created final result by adding non-existent content in original CD. In this way it is possible to kept the compatibility of the result of conversion in more IT devices by the function adding the 3rd content.

Generally, the content of Blu-ray Disc is protected by Advanced Access Content System (AACS).At the Content Transformation will protected by AACS In the case that content for other media and to conversion exports and sends, described content is generally by new content protective system Protection.Accordingly, it would be desirable to a kind of carry out issuing and based on new guarantor to the code being stored in Blu-ray Disc and being coded of content The process that this content is encrypted by protecting system scheme.In this case it is necessary to for the key of new encryption.Need one Protect the method for this key safely.

Fig. 4 is the concept map of the content conversion method according to exemplary embodiment.This content conversion method is exported by CMP (Export) represent.Blu-ray player as a kind of Content Transformation equipment obtains content and data from Blu-ray Disc.In described Holding in BDMV form, described data can include DfE.Additionally, context switching mechanism can obtain from server or CMP Export service Must change and export the information needed for content.Described information can include：Key, DfE and/or the information that provided by server Availability and mandate.Content Transformation equipment can receive content, data and information, and is converted to new by content, data and information The CMP file of flow data or CMP form.For example, CMP file can be ISO base media file form definition file (ISODF) Or media extract table (MET) form.

New flow data can be sent to can play the device of CMP file by external memory or network.Outside storage dress Put and can include conversion equipment (such as, such as flash memory and hard disk drive (HDD)).The device that can play CMP file can include CMP Player (such as, such as media player, mobile device and flat board PC).For example, user can will be outputted as regarding of CMP file The video content of storage in a flash memory, and is sent to another user by frequency storage.In another example, user can regarding output Frequently content uploading is to network attached storage (NAS) device, so that in the user that may have access to this NAS device can use this video Hold.

But, CMP file may need the number whether for user with this CMP file of broadcasting by numeral ecosystem service Word rights management (DRM) is play license and is verified, to prevent undelegated assault.It is described below and prevent from further not awarding The encryption of the assault of power.

According to the content conversion method of exemplary embodiment, high-quality content can be sent to other from Content Transformation equipment by user User or for playing other equipment of content.From the angle of content manufacturer, the intervention of manufacturer is not had to propagate content It is possible to various numeral ecosystems.

Fig. 5 is the schematic diagram of the process illustrating the content conversion method according to exemplary embodiment.With reference to Fig. 5, CMP Export Process includes 3 operations：There is provided thing to select, BDMV output and DfE replicate.Including selecting through offer thing in Blu-ray Disc Select, BDMV exports and the content of DfE duplication is converted into the CMP file can play in information technology (IT) device.

In detail, provide thing to select the process being to obtain inventory information, allow users to the content selecting to be changed and export, and Certification is for the content of output.It follows that BDMV output is to change and be output as CMP file the data being encoded to BDMV form Process.Finally, DfE replicates the process being to be replicated form without the content changed by file copying method.

As it is shown in figure 5, BDMV output and DfE replicate and can be executed in parallel.Additionally, BDMV output and any in DfE duplication It individual is executed first.

Generally speaking, in providing thing to select, Content Transformation equipment obtains inventory information and allows the user to select to be output Stream, and content is authenticated to export the stream of selection.For the stream needing form to change, in BDMV Export, according to showing The content conversion method of example embodiment is employed so that stream to be converted to before being output CMP file.On the other hand, at DfE In duplication, the content can being replicated by existing file copying method is replicated.The stream changed and/or can be replicated Content merged and export.Content Transformation equipment can illustrate instruction output completed output completion message.

Additionally, the stream selecting and CMP file need to have man-to-man relation.It is to say, when a stream is chosen so as to be output When, if successful execution conversion, then a CMP file would need to be output.

Three shown in Fig. 5 operation will be described with reference to Fig. 6 A to Fig. 8 in detail.

The thing that provides that Fig. 6 A and Fig. 6 B shows the content conversion method according to exemplary embodiment selects the schematic diagram of operation. In Fig. 6 A and Fig. 6 B, solid line means processing procedure, and dotted line means that data are transmitted.First, when beginning CMP output process When, perform to obtain the operation that thing inventory information is provided.In detail, Content Transformation equipment or Blu-ray player obtain and are stored in blue light Content certificate identifier (ID) in Advanced Access Content System (AACS) catalogue of CD, using obtain content certificate ID as It is sent to server or CMP output service to the request providing thing inventory information, and provide thing clear from server reception is corresponding Single information.There is provided thing inventory information can include that help content conversion equipment provides a user with in the case that Blu-ray Disc is supported The information of CMP output intent option.There is provided thing inventory information can include providing thing to select information and output inventory information, after a while will be to this It is described.

It follows that based on the offer thing inventory information obtaining, context switching mechanism determines whether there is and is useful in each Shown selectable offer thing is provided.Selectable offer thing is represented by Offer.When there is not available selectable offer During thing, Content Transformation equipment illustrates the disabled message of instruction output.This message is referred to as " exporting unavailable message ", this message Content can be defined in the server.On the contrary, when there is available selectable offer thing, Content Transformation equipment based on The offer thing inventory information obtaining shows selectable offer thing.User can pass through Content Transformation equipment based on the offer thing of display Select the content will changed and export.Alternatively, also the choosing to shown offer thing can be performed according to predetermined information Select, and without the input of user command.

When selecting or make according to the selection of predetermined information of user, Content Transformation equipment produces：Mandatory output data, not Exported data by the acquiescence that user rewrites and include that the offer thing by the content being selected by user being output selects information.Produce Raw offer thing selects information to define the listed files that will be included in CMP file.

Content Transformation device-to-server provides thing to select information, as output authorization requests.This request of server process, And information is corresponding exports inventory information with providing thing to select to the offer of content conversion equipment.Output inventory information indicates by carrying Whether the output selecting information request for thing is authorized to.Server also can provide the position of all of DfE, ISODF and MET etc..

Content Transformation equipment determines by providing thing selection information request based on the output inventory information receiving from server Whether output is authorized to.If output is confirmed as uncommitted, then Content Transformation equipment illustrates that this output of instruction is uncommitted Message.This message is referred to as " exporting uncommitted message ", and the content of this message can be defined in the server.

If on the contrary, output is confirmed as authorizing, then Content Transformation equipment determines whether there is the CMP literary composition that can store output The sufficient memory space of part.If it is determined that there is not the memory space of abundance, then Content Transformation equipment illustrates instruction storage sky Between not enough message.This message is referred to as " memory space inadequate message ", and the content of this message can be defined in the server.

If it is determined that there is sufficient memory space, then the location retrieval that Content Transformation equipment is specified from output inventory information is former Beginning CMP (OCMP).In the URL that OCMP can support in Blu-ray Disc or by server with BDMV content parallel memorizing.OCMP quilt In the external memory unit being stored in the internal storage unit of Content Transformation equipment or being connected with Content Transformation equipment.

There is provided thing inventory information can provide user interface (UI), Content Transformation equipment allows users to select by this user interface Effective offer thing exports content.Further it is provided that thing inventory information also can notify there is not selectable offer thing.Thing is provided Selection information represents the information of the offer thing being selected by user.Output inventory information includes that Content Transformation equipment performs output function Required information.Every information can be defined as XML document form.

The function providing thing inventory information provides and produces and be provided for the information needed for UI that thing selects.Further it is provided that The function of thing inventory information catches, according to following form, the offer thing selecting：The thing that provides selecting can be the follow-up behaviour of converted contents Work is used.

The CMP that need to be Blu-ray Disc mandate by content provider output configuration is referred to as providing thing.According to providing, whether thing is selected The output intent option selected and determine is referred to as sub-offer thing.There is provided thing to be " optionally ", sub-offer thing can be " necessary " or " can Choosing ".Thing inventory information is provided to be designed to support:Including the language-localized of translation, offer thing and son provide thing and bag Include the ability of the default option being pre-selected.

Content providing needs to provide and allows users to select or release the function providing thing.Additionally, content providing needs To start Content Transformation function in the case of selecting optional sub-offer thing without user.Main BDMV video, acquiescence BDMV audio frequency It is all automatically included in offer thing selection information with mandatory non-BDMV stream.For example, when user does not select to give tacit consent to BDMV audio frequency But when selecting another BDMV audio stream, provide thing to select information to include the stream being selected by user extraly.Thing is provided to select letter Breath can be considered to be the list that the part to CMP file configures.For example, thing is provided to select information can include the video selecting The list of editing, audio stream and captions.

Output inventory information provides that download from server or needs the OCMP from Blu-ray Disc output or partial information.Output is clear Single information includes with regard to the direct instruction how correctly configuring CMP file.But, output inventory information is not specified in being left to Hold the operational order of conversion equipment.Including the executory maximum flexibility of Informational support in output inventory information.

For example, as the method for producing output inventory information, can there is following two method.But, it is used for producing output The method of inventory information is not limited to following two method.

First method is for directly from the method providing thing to select information generation output inventory information.Select based on providing thing The XML document of information determine for produce CMP file part (for example, by the online DfE downloading from server, from blue light light The DfE of dish output, basic stream etc.) from where coming.Additionally, the information determining is used in output inventory information.Therefore, generation Output inventory information is constrained to the output inventory information of the offer thing selecting.

Second method starts from including the output inventory information of the information of the position with regard to all parts, and is independent on whether Part is chosen.This is the method for producing output inventory information, and the method is as selecting information to go based on offer thing Method except the part in addition to required part.Therefore, above two method produces identical output inventory information.

Output inventory information includes carrying out configuring required information to CMP file.But, output inventory information can not wrap Include authorization message or encryption information.The output process using output inventory information briefly described below.OCMP is placed on mesh Cursor position, and part is obtained from the source specified by output inventory information.Additionally, ZIP catalogue is produced in the ending of CMP file Raw.For obtaining the order of each part not included in output inventory information, and can set according to Content Transformation to optimize It standby is selected freely.

Fig. 7 A to Fig. 7 C is the schematic diagram of the BDMV output function illustrating the content conversion method according to exemplary embodiment.BDMV Output includes the operation repacking stream shown in Fig. 7 C.In Fig. 7 A to Fig. 7 C, solid line means processing procedure, and dotted line is anticipated Taste data transmission.

First, Content Transformation equipment or Blu-ray player obtain basic for export from BDMV mpeg 2 transport stream (M2TS) The re-encrypted key of stream.In order to obtain key from server, Content Transformation equipment is usable in defined in output inventory information Key positional information or positioning information.Re-encrypted key is used to common encryption (CENC) and encodes according to BDMV Data carry out re-encrypted.It follows that the re-encrypted that Content Transformation equipment pair is consistent with the requirement defining in the server The integrality of key and authenticity are verified.

Content Transformation equipment also obtain concurrently with the operation of above-mentioned acquisition re-encrypted key from BDMV M2TS output basic The DfE of stream.In order to obtain DfE, Content Transformation equipment is usable in DfE positional information or positioning defined in output inventory information Information.For example, DfE may be present in BDMV content and is in the position supported by server.DfE can comprise two types.One Planting is MET, and another kind is ISODF.It follows that the Content Transformation equipment pair DfE consistent with the requirement defining in the server Integrality and authenticity are verified.

Content Transformation equipment determines whether mistake is tested in obtaining the operation of operation neutralization acquisition DfE of re-encrypted key Card.If it is determined that mistake is verified, then Content Transformation equipment illustrates the message of the invalid content of instruction output.This message is referred to as " output invalid message ", and the content of this message can be defined in the server.

If on the contrary, mistake is not determined to be verified, then Content Transformation equipment processes BDMV.In detail, Content Transformation Related BDMV playlist from BDMV catalogue and playitems playitem (that is, editing) are processed by equipment, so that identify will be from The basic stream of BDMV M2TS output.Output inventory information defines the playlist being output, playitems playitem and PID.In order to know Not by the reference editing (M2TS) exporting from editing and basic stream, playlist is resolved by Content Transformation equipment.Additionally, it is interior Hold conversion equipment and perform content protecting process (CPP) to remove the protection to M2TS.

It follows that as it is shown in fig. 7, basic stream is repacked by Content Transformation equipment.In detail, Content Transformation equipment to come Demultiplex from the basic stream of the M2TS being not protected.The video flowing of output and audio stream can be stored in different buffers In.

Which BDMV stream substantially will be output according further to ISODF program according to MET program and be determined by Content Transformation equipment. Additionally, which data during the BDMV that Content Transformation equipment is to output flows substantially will be re-encrypted still not encrypted carrying out really Fixed.It follows that Content Transformation equipment performs common encryption (CENC) to the data that will be re-encrypted.At output and encryption After both reasons are performed, the data being defined by output inventory information exporting are copied as ISODF by Content Transformation equipment.

Content Transformation equipment needs to export the audio stream of at least one main audio BDMV coding from the M2TS of BDMV coding.Additionally, Content Transformation equipment needs the video flowing of the M2TS output main video BDMV coding from BDMV coding.
