The detailed description of embodiment
Fig. 1 is the component drawings that is used to manage the distributed scalable system 100 of not protected and shielded content.System 100 for example is connected to wired and/or dedicated network 102 in the home environment in privately owned environment.Dedicated network 102 can be for example for example Intranet, Cellular Networks, Local Area Network, VPN(Virtual Private Network), personal area network (PAN), Authorized Domain (AD) etc. in the privately owned user environment such as private vehicle, private business, private building.
For example the content of digital video, DAB, digital photos, digital figure, digital cartoon, digital text, digital multimedia etc. via be connected to dedicated network 102 server 104 and distributed clients machine 106,108 receive in the dedicated network 102.Content can be from for example receptions such as storage card 110, the Internet connection or web site url 112, photo CD 114, music CD 116, DVD 118, satellite downlink 120, digital tuner, cable TV network.Content also can receive from other source, for example, such as equipment such as tuner/decoder and set-top box, such as public networks such as Cellular Networks and cable television networks, such as portable terminals such as mobile phones, such as media players such as MP3 player, game console and such as portable computing devices such as PDA(Personal Digital Assistant)s.
The physical media storage device 136 that is connected to dedicated network 102 is content protecting and checking nodes of dedicated network 102.Physical media storage device 136 is physically stored movable storage mediums such as for example music CD 116 that is associated with for example Digital Right Management (DRM) system, copy protection (CP) system, conditional access (CA) system and technology protection measure content protective systems such as (TPM) and DVD 118.Physical media storage device 136 is also stored the component software that is associated with content protective system; for example, keys for encryption/decryption, digital license, digital certificate, digital watermarking, equipment registration, user's registration, active coding, subscription, digital signature, device id and user ID.Physical media storage device 136 is still at the batch loading equipemtn that does not have to handle under the situation of user interactions n storage, management and content verification scalablely.The day of the content of all storages and management is when aiming at being requested or work as content verification and/or be provided for the user when being used to complete.Additional physical media storage device 136 (not shown) can be connected to dedicated network 102 provides scalable content protecting and authentication function.In addition, the content protecting hardware/software components also can be stored in the server 104.
Fig. 2 illustrates the process flow diagram of being managed being used to of carrying out the process 200 of not protected and shielded content by system 100.After in dedicated network, receiving content (step 202), the metadata (step 204) that is associated with received content from the user search of content itself, public network, remote data base, local data base, metadata supplier and dedicated network for example.Will be in the retrieval of following description to metadata such as for example content types.After having retrieved the metadata that is associated, making received content based on the metadata that is associated is not protected or shielded judgement (step 206).Based on the metadata that is associated, then can be in dedicated network free and optionally store, manage and distribute not protected content (step 208).On the other hand, the metadata that is associated is used to sign and shielded content associated content protection system (step 210).Comprise with shielded content associated content protection system, for example Digital Right Management (DRM) system, copy protection (CP) system, conditional access (CA) system, technology protection measure (TPM) etc.
In case identified the associated content protection system, promptly to user's display message of dedicated network so that the required hardware/software components (step 212) of retrieval associate content protection system.In addition or as an alternative, relevant with required hardware/software components and/or content protective system information can be logged so that check for the user when being requested.For example from the required hardware/software components of user search associated content protection system of content itself, public network, local data base, remote data base, content provider, storage medium, memory device and dedicated network.Required hardware/software components comprises, for example storage medium, memory device, smart card, Dao Er chip, keys for encryption/decryption, digital license, digital certificate, digital watermarking, media player, equipment registration, user's registration, active coding, subscription, digital signature, device id, user ID etc.May there be the various combination of two or more hardware/software components in content protective system in dedicated network, for example MP3 DRM system may need the existence of Portable MP 3 media player and MP3 DRM software.To the essence of the visit of protected content in the dedicated network and scope can to small part based on required hardware/software components.Required hardware/software components is retrieved (step 214) and/or is verified as and is present in (step 216) in the dedicated network.Afterwards, can in dedicated network, optionally store based on the metadata that is associated, management and distributing protected content.
The required hardware/software components of being carried out by server 104 and/or physical media storage device 136 of software verification is present in the dedicated network 102.Required hardware/software components can be stored in server 104 and/or the physical media storage device 136 so that retrieval of carrying out and/or checking subsequently.Server 104 and/or physical media storage device 136 can be programmed and detect required nextport hardware component NextPort, and for example whether portable electronic device, Dao Er chip etc. are connected to dedicated network 102 directly or indirectly via the assembly of system 100.
Can retrieve the metadata that is associated from content sources, for example CD can be by identifying such as its catalogue metadata such as (TOC).This binary structure is converted into the sexadecimal string, and submits to as the part to the metadata query of the metadata databases such as metadata database on the web server 140 for example.The metadata database of being inquired about returns one group of unique id string then, and they are connected in series the metadata that produces sign CD.This id string is stored in the local data base, for example in the server 104, so that sign CD.Photo CD can be for example by its file label sign.For example use Windows (trade mark) 32API function G etVolumeInformation to retrieve file label.
The metadata that is associated with DVD can be retrieved based on three independent identifiers.When DVD was added to system 100 first, Microsoft (trade mark) DirectX interface IDVDInfo2 obtained the 64 item sign indicating numbers that system generates for this DVD.Clauses and subclauses of search matched in the metadata database on the web server 142 for example then.If in metadata database, do not find record, then read unique product code (UPC) from the DVD dish.If can not find, then import this UPC to user prompt, it generally finds on bonnet as bar code.Use UPC to come information and the front cover pattern of query metadata database then to obtain this DVD.Metadata database also returns with this UPC and is stored in dish ID in the database on the server 104.When DVD was stored in the server 104, Microsoft (trade mark) ID was used as key.When DVD was put into the DVD driver once more, Microsoft (trade mark) ID was used to search the record in the server 104.Other suitable method of sign DVD is conspicuous to those skilled in the art.
The metadata that is associated with content comprises, for example title, placard or front cover pattern, audio frequency and/or video clipping, general introduction, author, performing artist, producer, school, grading, version, comment etc.To DVD and CD, the supplier retrieves metadata from metadata.To Digital Television or radio broadcasting, metadata can comprise for example electronic program guides (EPG).In addition or as an alternative, can retrieve the metadata that is associated with the content that is received via user interface 122,134 users from dedicated network.
Content can be stored in the database on the server 104 to optimize playback or to present by its original or original form.Perhaps, content can be by the storage of compression form.The metadata that is associated also can be stored in the database in the server 104.The photo form of being supported is detected by extension name in the file and signature bytes.Each effective document uses the operating system file replicate run to be copied to target directory in the server 104 then.During reproduction process, test and dwindle photo resolution and present resolution, thereby any image resolution ratio that allows to be stored shows to playback or display device 122,124,126,128 with the maximum that is suitable for playback apparatus 108.
Fig. 3 A-N is based on the screenshot capture of the content of being stored on the associated metadata management server 104.Fig. 3 A illustrates the content of being stored in the server 104 can be classified as film (movies), music (music), photo (photos), internet content (internet) and playlist (playlist).In Fig. 3 B-D, movie contents can be by all available titles (title), school (genre), performer (actor), director (director) and title (title) management.The poster art images that also can show film.As shown in Fig. 3 E-H, music content can be by all available titles (title), school (genre), artist (artist), album name (albumtitle) and track title (track title) management.The front cover pattern diagram picture that also can show special edition.Fig. 3 I-J illustrates photo and can classify by school (genre), album title (photo album title) and single photo title (photo title).As shown in Fig. 3 L-M, web link (web link) and the internet search engine (searchengine) stored also can be classified.Fig. 3 A illustrates the secure icon/button (security) that can be used for being provided with the security settings of leading subscriber, and Fig. 3 N illustrates the use that is used for the personal code work (user code) of the safety management of the content of being stored.
Fig. 3 K and 4A-I are the screenshot captures that the playlist of creating the content of being stored on the server 104 is shown.Playlist can use the music shown in Fig. 3 A, photo or playlist buttons to create.Can create the mixing of dissimilar contents, such as photograph slideshows, so that via client computer 108 playback or present on playback apparatus 124,126,128,130 with track.As shown in Fig. 4 A-F, can use theme (theme), school, artist and the title of the audio content of being stored to create the playlist of the track of being stored.But Fig. 4 G-H illustrates preview and the digital photos selecting to be stored is followed the playlist of track.Fig. 4 I is a playlist summary, and it for example comprises, the title of single track and photo, the total duration of playlist (duration).System software can be used for generating the playlist of the combination of film, music and photo, and can be used for controlling the transition between the dissimilar contents, fading in and fade out such as music and/or video between scene, the track etc.
The content of being stored can optionally be distributed to playback apparatus 124,126,128,130 from server 104 by client computer 108.System software comprises the network flow service (NSS) on the server 104, and the network flow CLIENT PROGRAM (NSC) on each client computer 108.The all the elements of being stored on the NSS accessible services device 104, and set of number TV tuner and satellite/CATV (cable television) descrambler card.Content is supplied as stream of packets by NSS, and these streams can comprise the player media types of any support, for example MPEG-2, MPEG-4, WMA, WAV, WMV, DV etc.Also can be to stream encryption to prevent " go-between " replication attacks.
Select in response to the user, the NSC on the client computer 108 is current stream table (CST) inquiry NSS, and this table is the tabulation of current in progress stream.The content of CST can show that this allows NSC to participate in the playback of this stream to the user.Thereby a NSC can participate in the stream of the TV channel that another NSC using to be transmitted, as long as perhaps there is the tuner can be with adding channel to CST.Perhaps, client computer 108 can participate in the multicast of film or other video flowing.CST comprises the stream metadata of describing content type, such as " video ", " audio frequency " or stream name, such as " Channel 7 " or " The Fifth Element " and out of Memory, for example controls client computer 108.The stream metadata is shown as demonstration (OSD) on the screen of the information relevant with stream itself.
When the user selects stream, when for example film, slide demonstration or music were come playback, NSC was set up to the connection of NSS, and asked this stream to begin.To unicast stream, NSS creates and to spread the line sending journey, and it will be handled to the transmission of the flow data of client computer 108 and from the special play-back request of client computer 108, and for example rollback, FF play and suspend etc.To connection, provide the port of receiving group stream packets thereon to NSC to unicast stream.After the line sending journey was spread in setting, NSS continued to monitor connection request.
Real-time protocol (rtp) and real-time stream transmit the playback that agreement (RTSP) is used to transmit and control stream.These agreements permission client computer 108 time-outs and execution are to the special play-back of Media Stream, such as the bookmark part of content.NSC will carry out the buffering of each stream that it is connected, to solve network delay.
Each client computer 108 has the UPnP player service (UPS) that operation allows any UPnP that follows (universal plug and play) reference mark (CP) to give an order to client player 108.Spread by combination UPnP agreement and digital content and to take affair, NSS can be configured to will the stream multicast to the client computer 108 of wishing participation.This is convenient to one or more synchronized playback that flow to a plurality of client computer 108.A client computer 108 is designated as the controller of multicast, and gives an order with the playback of control content or present by server 104.Other client computer 108 can add or withdraw from any moment during multicast.
