[0081] 对于普通的数字电视广播节目,用户根据节目描述信息中的节目类型值获知该节目是数字电视广播节目,根据数字电视广播节目的物理参数调频到该节目对应的频点接收该频点TS流,根据该数字电视广播节目TS流PID信息从TS流过滤出该数字电视广播节目的内容,再解复用并展示过滤出的数字电视广播节目内容。 [0081] For ordinary digital television broadcast program, the user knows according to the program type value of the program description information of the program is a digital television broadcast program, receiving the frequency depending on the physical parameters of digital television broadcast program FM to the program corresponding frequency TS stream, according to the digital television broadcast program stream PID TS stream from the TS filtering the contents of the digital television broadcast program, the demultiplexed digital television broadcast program and then display the contents filtered and used.

[0082] 对于准点播广播/宽带融合节目,用户可以采取和与直播广播/宽带融合节目类似的方法,在播放数字电视广播节目的过程中实现对节目的时移操作。 [0082] For the broadcast / broadband quasi-fusion demand program, the user can take and fused to a broadcast / broadband broadcast program in a similar manner to achieve the shifting operation of the program during playback of the digital television broadcast program.

[0083] 以上所述技术内容均以网络侧生成的统一的EPG为基础;在实际应用中,也可以如图5所示由终端侧生成统一的EPG,并以此为基础获取媒体内容。 [0083] The technical content of the above network side are generated based on the unified EPG; In practical applications, a unified EPG generated by the terminal side as shown in FIG. 5 may be, and in order to obtain the media content is based.

[0084] 参见图5,图5为本发明另一较佳实施例的媒体内容获取系统。 [0084] Referring to FIG. 5, FIG. 5 acquiring system according to another preferred embodiment of the invention, the media content. 图5中,数字电视广播服务器520、IPTV宽带服务器530分别与内容标识(CRID)提供服务器510、数据收发模块541相连;节目描述信息存储模块542、终端侧位置解析模块543分别与数据收发模块541、EPG处理模块544相连;EPG处理模块544还与位置解析服务器550相连,并且还可以进一步与策略库546相连;媒体播放模块545分别与终端侧位置解析模块543、位置解析服务器550相连。 5, the digital television broadcast server 520, IPTV broadband server 530 are provided with a content identifier (the CRID) server 510, coupled to a data transceiver module 541; program description information module 542, terminal-side location resolution module 543, respectively, and the data transceivers 541 , the EPG processing module 544 is connected; the EPG processing module 544 is also connected to a position-resolution server 550, and may be further connected to a policy database 546; a media player module 545, respectively, and the terminal-side location resolution module 543, the location resolution server 550 is connected. 其中,数据收发模块541、节目描述信息存储模块542、终端侧位置解析模块543、EPG处理模块544、媒体播放模块545以及策略库546通常设置于HNED 540中。 Wherein the data transceiver module 541, program description information module 542, terminal-side location resolution module 543, EPG processing module 544, media player module 545 and policy store 546 is typically provided in the HNED 540.

[0085] 在实际应用时,为了能将数字电视广播节目与IPTV宽带节目统一起来以生成统一的EPG,CRID提供服务器510需要为数字电视广播节目和IPTV宽带节目分配统一的CRID,并将为数字电视广播节目、IPTV宽带节目所分配的CRID分别通知给数字电视广播服务器520和IPTV宽带服务器530。 [0085] In practice, in order to be able to digital television broadcast program with the IPTV Broadband unified EPG program to generate a uniform, CRID CRID providing server 510 need unified digital television broadcast program and a program distribution IPTV broadband, and digital TV broadcasts, IPTV broadband program notifies the assigned CRID server 520 to the digital television broadcasting and broadband IPTV server 530. 通常,CRID提供服务器510为具有相同节目内容的数字电视广播节目和IPTV宽带节目分配相同的CRID。 Typically, CRID providing server 510 assigned the same CRID as a digital television broadcast program and a program having the same broadband IPTV program content.

[0086] 收到来自CRID提供服务器510的CRID时,数字电视广播服务器520和IPTV宽带服务器530分别将收到的CRID携带于相应节目(所分配的CRID所针对的数字电视广播节目和IPTV宽带节目)的Si、宽带内容向导(BCG)数据中发送给数据收发模块541 ;数据收发模块541将来自数字电视广播服务器520和IPTV宽带服务器530的CRID以及Si、BCG 数据中的节目描述信息发送给节目描述信息存储模块542,还将来自数字电视广播服务器520和IPTV宽带服务器530的CRID以及Si、BCG数据中的位置解析信息发送给终端侧位置解析模块543。 [0086] CRID receives from the server 510 to provide the CRID, the digital TV broadcast CRID IPTV server 520 and 530 respectively receive broadband server is carried in the corresponding program (digital television broadcast program and a program IPTV Broadband assigned CRID for which ) of Si, broadband content data transmitted to the transceiver module 541 Guide (BCG) data; a data transceiver module 541 from the digital television broadcast server CRID 520 and IPTV broadband server 530 and Si, the BCG data in the program description information to the program description information module 542, also from a digital television broadcast CRID 520 and the IPTV server 530 and broadband server Si, BCG data position analyzing information to the terminal-side location resolution module 543. [0087] 通过数据收发模块541收到CRID以及数字电视广播节目和IPTV宽带节目的节目描述信息时,节目描述信息存储模块542根据CRID建立所述数字电视广播节目、IPTV宽带节目的节目描述信息之间的对应关系,并将建立了对应关系的数字电视广播节目描述信息、IPTV宽带节目描述信息发送给EPG处理模块544。 [0087] When the received digital television broadcast program CRID and broadband IPTV program and the program 541 through the data transceiver module description information, program description information storing module 542 according CRID establishing the digital television broadcast program, IPTV broadband program description information of the program correspondence between, and development of a digital television broadcast program description information corresponding relationship, IPTV broadband program description information to the EPG processing module 544. 同理,通过数据收发模块541收到CRID以及数字电视广播节目和IPTV宽带节目的位置解析信息时,终端侧位置解析模块543 在该CRID和所述数字电视广播节目、IPTV宽带节目的位置解析信息之间建立对应关系。 Similarly when the received CRID and location resolution information of digital television broadcast program by program and IPTV broadband data transceiver module 541, terminal-side position of the parsing module 543 parses the CRID and location information of the digital television broadcast program, a program IPTV Broadband establishing correspondence between.

[0088] 收到来自节目描述信息存储模块542建立了对应关系的数字电视广播节目、IPTV 宽带节目的节目描述信息,EPG处理模块544采用通用的格式(如XML,HTML, XHTML)对建立了对应关系的数字电视广播节目、IPTV宽带节目的节目描述信息进行描述,最终生成统一的EPG页面。 [0088] receive the digital television broadcast program from the program description information module 542 to establish a correspondence relationship, IPTV program broadband program description information, EPG processing module 544 using a common format (e.g., XML, HTML, XHTML) for establishing corresponding the relationship between digital television broadcasts, IPTV broadband program, program description information is described, and ultimately generate a unified EPG page. 可见,从统一的EPG页面中既可以找到数字电视广播服务器520所提供的数字电视广播节目内容的节目描述信息,也可以找到IPTV宽带服务器530所提供的IPTV 宽带节目内容的节目描述信息;并且,这两种节目描述信息之间还存在对应关系。 Seen from the unified EPG page may be found on digital television broadcasting server program of digital television broadcast program content provided 520 description information, you can also find programs IPTV broadband program content IPTV broadband server 530 provided descriptive information; and, these two programs are also described there is correspondence between the information.

[0089] 实际上,所述对应关系的建立方式可能很简单,如:将CRID相同的数字电视广播服务器310、IPTV宽带服务器330所提供的节目的节目描述信息按下面所述的规则,存储于如表6所示的节目描述信息存储表中。 [0089] Indeed, to establish the correspondence relationship may be very simple manner, such as: the 310, IPTV broadband server program 330 provides the same CRID digital television broadcast program server according to the following description of the rule information stored in as shown in table 6 describes the program information storage table.

[0090] 当然,如果EPG处理模块544与策略库546相连,EPG处理模块544在生成统一的EPG页面时还可以进一步考虑策略库546中的EPG生成策略。 [0090] Of course, if the EPG processing module 544 is connected with the policy library 546, EPG processing module 544 may further consider the policy repository 546 EPG generation strategy in generating a unified EPG page Shihai. 根据EPG生成策略生成统一EPG页面的具体方法与现有技术中的根据EPG生成策略生成普通EPG页面的方法相同。 The method of the same EPG generation strategy to generate ordinary EPG page prior art according to the specific method to generate a unified strategy to generate EPG EPG page with. 所述EPG生成策略包括:用户和/或EPG服务器对EPG页面的生成策略。 The EPG generation strategy comprising: a user and / or policy of the EPG server generates EPG page. 实际上,图3中的浏览器341也可以与策略库相连,以便在生成统一的EPG页面时进一步考虑策略库中的EPG 生成策略。 In fact, in Figure 3 browser 341 can also be connected with the policy bank, in order to further consider strategies library EPG generation strategy in generating a unified EPG page.

[0091] 具体而言,节目描述信息存储模块542所存储的节目描述信息通常是经过解析的。 [0091] Specifically, the program description information module 542 stored in the program description information is usually parsed. 对于SI而言,解析得到的PAT、PMT、NIT、SDT等表通常集中存放;对其它信息而言,则通常按表6所示的节目描述信息存储表中,对该表的说明如下: For the SI, the parsed PAT, PMT, NIT, SDT tables are typically stored centrally and the like; other information, it is usually in the program shown in Table 6 storage table description information, the description below table:

[0092] (I)CRID=SI和BCG数据中都包括该字段,如表6所示,作为节目描述信息的第一级索引,将具有相同CRID的广播节目A1、A2,宽带节目A3、A4的节目描述信息组织在一起。 [0092] (I) CRID = SI and BCG data includes the field, as shown in Table 6, the program description information as the first level index, the broadcast program with the same CRID A1, A2, broadband program A3, A4 the program description information organization together. .

[0093] (2) 一个标记(flag),用于标识节目是数字电视广播节目还是IPTV宽带节目,即: 表明节目描述信息是来自Si,还是来自BCG数据。 [0093] (2) a marker (In Flag), is used to identify the program or the digital television broadcast program broadband IPTV programs, namely: show program description information from Si, or from the BCG data.

[0094] (3)相应数字电视广播节目和IPTV宽带节目的节目描述信息。 [0094] (3) the corresponding digital television broadcast program and a program broadband IPTV program description information.

[0095] 生成的节目描述表可以如表6所示: [0095] The program descriptor table may be generated as shown in Table 6:

[0096] 表6 [0096] TABLE 6

[0097] 由于节目描述信息是对节目内容各个方面属性的描述,因此对于数字电视广播节目而言,除了CRID之外,下列字段(可从EIT表中得到)通常也是必须的: [0097] Since the program description is a description of various aspects of the program content properties, so for digital television broadcast program, in addition to the CRID, the following fields (available from EIT table) usually necessary:

[0098] original_network_id、 transport_stream—id、 service—id、 event_id, start— time,duration,title (从short_event_descriptor 中得到) [0098] original_network_id, transport_stream-id, service-id, event_id, start- time, duration, title (obtained from the short_event_descriptor)

[0099] 除了上述字段之外,还有可能得到的内容属性有: [0099] In addition to the above fields, there may be obtained content attributes are:

[0100] Synopsis (从EIT 表的short_event_descrriptor 禾口extended_event_ descriptor 中得到); [0100] Synopsis (obtained from short_event_descrriptor Hekou extended_event_ descriptor EIT table);

[0101] ParentGuidence (从EIT 表的parent—rating—descriptor 中得到);[0102] Genre (从EIT 表的content_descriptor 中得至Ij ); [0101] ParentGuidence (obtained from the parent-rating-descriptor EIT table); [0102] Genre (prepared from content_descriptor EIT table to Ij);

[0103] Language (从EIT 表白勺multilingual—component—descriptor 中得至Ij ); [0104] AVAttribute (从SDT 表的component_descriptor 中得至Ij )。 [0103] Language (from EIT declare spoon multilingual-component-descriptor to obtain the Ij); [0104] AVAttribute (from component_descriptor SDT table to obtain Ij).

[0105] 对于IPTV宽带节目而言,除了CRID之外,通常只有title是肯定能获得的。 [0105] For IPTV broadband program, in addition to the CRID, usually only the title is certainly available. 但是, 根据IPTV宽带节目的数据结构,还可以获得Synopsis、ParentGuidence、Genre、Language、 AVAttribute 等从EIT 中也能获得的信息;以及Keyword、CreditsList, AwardsList, ProgramReview等从EIT表中无法获得的信息。 However, the data structure IPTV broadband program, further information can be obtained Synopsis, ParentGuidence, Genre, Language, AVAttribute the like can be obtained from the EIT; and an information Keyword, CreditsList, AwardsList, ProgramReview the like can not be obtained from the EIT table. 并且,由于IPTV宽带节目自身的特性,可能还存在节目的有效期、购买信息等信息。 Furthermore, since the characteristics of IPTV broadband program itself, there may also be valid for the program, purchase information and other information.

[0106] 对于相同的节目内容,EPG处理模块544在内容生产相关的那些属性(Title、 Synopsis、ParentGuideneθλ Genre、Language、Keyword、CreditsListΛ AwardsListΛ [0106] for the same program content, EPG processing module 544 associated with the production of those attributes (Title, Synopsis, ParentGuideneθλ Genre, Language, Keyword, CreditsListΛ AwardsListΛ content

ProgramReview......)中取最大集,或是预先定义在EPG页面中展示的内容生产相关属性 ProgramReview ...... taking the maximum set), or the contents of a page displayed in the EPG predefined attributes related to the production

(由厂商或用户决定)。 (Determined by the manufacturer or user).

[0107] 另外,位置解析服务器550可以既对IPTV宽带服务器530提供服务又对数字电视广播服务器520提供服务,也可只对IPTV宽带服务器530提供服务。 [0107] Further, the location resolution server 550 may provide both broadband IPTV service server 530 also provides a digital TV broadcast service server 520, may only provide services to broadband IPTV server 530. 针对前一种情况而言, 所有的位置信息都是由位置解析服务器550解析CRID得到的;针对后一种情况而言,位置解析服务器550解析CRID得到的是获取IPTV宽带节目的位置信息,数字电视广播节目的定位信息贝丨J直接根据其original_network_id、transport_stream_id、service_id、event_ id, start_time, duration 生成。 For the former case, the position information are all resolved by the location resolution server 550 CRID obtained; for the latter case, location resolution server 550 parses the IPTV CRID is obtained broadband program position information, digital location information of television broadcast programs according to its shell Shu J original_network_id, transport_stream_id, service_id, event_ id, start_time, duration generated directly.

[0108] 在生成统一的EPG页面之后,EPG处理模块544将生成的EPG页面中的CRID发送给终端侧位置解析模块543。 [0108] After generating the unified EPG page, the EPG processing module 544 generates an EPG page to the terminal-side position of the CRID resolution module 543. 当因用户的选择而收到了EPG页面中某个节目被选中(假设被选中的是数字电视广播节目,或者默认选择数字电视广播节目)的指令(包括指示是数字电视广播节目或是IPTV宽带节目的节目类型,以及节目描述信息)时,EPG处理模块544 获取被选中节目对应的CRID,并将该CRID和被选中的节目的节目类型发送给终端侧位置解析模块543 ;终端侧位置解析模块543根据自身所建立的涉及位置信息的对应关系,查找收到的CRID所对应的具有所述节目类型的数字电视广播节目的位置信息,并将找到的位置信息发送给媒体播放模块545,由媒体播放模块545获取并显示收到的位置信息所指向的数字电视广播节目内容。 When received by the user's selection of a program in the EPG page is selected (assuming the selected program is a digital television broadcasting, or digital television broadcast program selected by default) instructions (including indication of a digital television broadcast program or program IPTV Broadband when the type of program, and program description information), the EPG processing module 544 acquires CRID corresponding to the selected program, and transmits the selected program CRID and the program type to the terminal-side location resolution module 543; terminal-side location resolution module 543 the location information relates to the correspondence relationship itself established, to find the CRID corresponding to the received location information of the program type having a digital television broadcast program, and transmits the location information to find the media player module 545, by the media player module 545 acquires and displays the contents of the digital television broadcast program received location information is directed. 具体的数字电视广播节目内容获取方法与图3中所描述的相应获取方法相同。 Specific digital television broadcast program corresponding to the content acquisition method of acquiring the same manner as in FIG. 3 described.

[0109] 在媒体播放模块545接收并显示数字电视广播节目内容时,EPG处理模块544还能根据收到的指令对接收的数字电视广播节目内容进行时移控制。 When shifting control [0109] receive and display digital television broadcast program content in the media player module 545, EPG module 544 can process the received digital television broadcast program content in accordance with the received instruction. 进行时移控制的过程通常为:EPG处理模块544收到进行时移的时移指令(该指令通常来自于用户所应用的遥控器, 其中通常包含IPTV宽带节目的节目类型和数字电视广播节目的数字电视广播节目描述信息),进而从EPG页面中找到所述数字电视广播节目描述信息所对应的CRID,并将该CRID、 时移指令中的时间位置和需要的时移节目的节目类型发送给终端侧位置解析模块543 ;终端侧位置解析模块543根据自身所建立的涉及位置信息的对应关系,查找收到的CRID所对应的IPTV宽带节目的位置信息,并将收到的所述时间位置和找到的位置信息发送给媒体播放模块545,由媒体播放模块545根据收到的位置信息获取并显示偏移了所述时间位置的IPTV宽带节目内容。 Shift control at the time the process is generally as follows: when a time shift module 544 receives the EPG processing for shifting instructions (which typically applied from a user remote control, which typically comprises a broadband IPTV program type and program of digital television broadcast program digital television broadcast program description information), and further find the digital television broadcast program from the EPG page description information corresponding to the CRID, and that the CRID, program type when the shift position of the time-shifted program of instructions and is sent to the time required terminal-side location resolution module 543; terminal-side location resolution module 543 relates to the location information according to the correspondence established by itself, to find the CRID corresponding to the received broadband IPTV program location information and the location and time of receipt found position information is transmitted to the media playback module 545, and acquires the offset of the display program of the IPTV broadband content temporal position according to the position information received by the media player module 545. 具体的IPTV宽带节目内容获取方法与图3中所描述的相应获取方法相同。 Specific broadband IPTV program content acquisition method of acquiring the same manner as the corresponding FIG. 3 described. [0110] 由以上所述可见,位于HNED 540中的终端侧位置解析模块543能够向媒体播放模块545提供用于接收媒体内容的位置信息。 [0110] apparent from the above, the HNED 540 located in a terminal-side location resolution module 543 can provide location information for the received media content to the media playback module 545. 在实际应用中,也可以在网络侧设置位置解析服务器550,由位置解析服务器550向媒体播放模块545提供用于接收媒体内容的位置信息。 In practical applications, it may be provided position analyzing server 550 on the network side, for receiving position information providing media content to the media player module 545 by the location resolution server 550. 当然,位置解析服务器550中需要存储根据CRID建立了对应关系的数字电视广播节目位置解析信息、IPTV宽带节目位置解析信息。 Of course, the location resolution server 550 is established to be stored in the digital TV broadcast program corresponding to the position relationship between the analysis information in accordance with CRID, IPTV broadband program location analysis information.

[0111] 具体而言,当收到来自EPG处理模块544的CRID时,如果终端侧位置解析模块543 没有查找到收到的CRID所对应的位置信息,终端侧位置解析模块543就向EPG处理模块544返回失败响应,EPG处理模块544收到该失败响应时将曾向终端侧位置解析模块543发送的CRID发送给位置解析服务器550 ;当然,EPG处理模块544也可以直接将CRID发送给位置解析服务器550。 [0111] Specifically, when receiving the EPG CRID processing module 544, if the terminal side does not find the location resolution module 543 receives position information corresponding to the CRID, the terminal-side location resolution module 543 to the EPG processing module 544 failure response is returned, EPG processing module 544 receives the position had CRID resolution server 550 transmits to the terminal-side location resolution module 543 transmits the failure response time; of course, EPG processing module 544 may be directly transmitted to a location resolution server CRID 550.

[0112] 收到来自EPG处理模块544的CRID (通常还带有节目类型)时,位置解析服务器550查找该CRID所对应的位置信息,并将找到的位置信息发送给媒体播放模块545。 When the [0112] received CRID from the EPG processing module 544 (usually with a program type), resolution server 550 to find the location of the CRID corresponding to the location information, and transmits the found location information module 545 to the media player. 位置解析服务器550查找位置信息的方法与前述的终端侧位置解析模块543查找位置信息的相应方法相同。 Analytical methods identical to the corresponding location information server 550 to find the location of the terminal-side location resolution module 543 to find the position information.

[0113] 由于EPG处理模块544和终端侧位置解析模块543配合实现了统一EPG页面的生成以及节目位置信息获取的功能,因而将EPG处理模块544和终端侧位置解析模块543统一称为EPG生成及位置信息获取单元。 [0113] Since the EPG processing module 544 and a terminal-side location resolution module 543 implemented with a program generation function and the position information acquired unified EPG pages, and thus the EPG processing module 544 and a terminal-side location resolution module 543 and collectively referred to as EPG generation position information acquiring unit.

[0114] 图5所示系统获取媒体内容的操作过程总体如图6所示。 During operation of the system shown in [0114] FIG. 5 generally acquiring media content as shown in FIG. 参见图6,图6为图5所示的系统获取媒体内容的流程图,该流程包括以下步骤: Referring to FIG. 6, FIG. 6 is a flowchart of the system shown in FIG. 5 acquiring media content, the process comprising the steps of:

[0115] 步骤601至步骤602 :CRID提供服务器分别向数字电视广播服务器和IPTV宽带服务器发送统一的CRID。 [0115] Step 601 to step 602: CRID unified providing server are transmitted to the digital television broadcast CRID and IPTV servers broadband server.

[0116] 步骤603至步骤607 :数字电视广播服务器将携带有CRID的数字电视广播节目描述信息发送给HNED ; IPTV宽带服务器将携带有CRID的IPTV宽带节目描述信息发送给HNED。 [0116] Step 603 to step 607: a digital television broadcast CRID server carrying the digital television broadcast program description information to the HNED; IPTV broadband server of the IPTV carrying broadband CRID program description information to the HNED. HNED利用CRID对收到的数字电视广播节目描述信息、IPTV宽带节目描述信息建立对应关系并存储于节目信息表中,还根据建立有对应关系的CRID、数字电视广播节目描述信息和IPTV宽带节目描述信息生成统一的EPG页面。 HNED using CRID receiving a digital television broadcast program description information, program description information of IPTV broadband and establishing the corresponding relationship stored in the program information table, according to further establish a correspondence between CRID, the digital television broadcast program description information and program description IPTV Broadband information generation unified EPG page.

[0117] 步骤608至步骤609 :数字电视广播节目被选中,在该节目相应的节目描述信息中获取它的位置信息,并获取该位置信息所指向的数字电视广播节目内容。 [0117] Step 608 to step 609: digital television broadcast program is selected, the corresponding program in the program description information acquired its position information, and acquires the content of the digital television broadcast program pointed position information.

[0118] 步骤610至步骤612 :HNED获知要进行时移控制等媒体控制操作。 [0118] Step 610 to step 612: HNED known shift control to be performed when the media control operations. 具体而言,可以是HNED中的EPG处理模块收到进行时移的时移指令后确定要进行媒体控制操作;也可以是EPG处理模块根据自身设置确定要进行媒体控制操作。 Specifically, after the shift instruction may be determined when the shift when the HNED receives the EPG processing module to be performed for media control operation; EPG may be a media processing module determines to perform control operation according to its own settings.

[0119] EPG处理模块544从节目描述信息表或EPG页面中获取当前接收的数字电视广播节目的CRID,并终端侧位置解析模块543中获取该CRID所对应的IPTV宽带节目位置信息, 再获取并显示位置信息所指向的IPTV宽带节目内容。 [0119] EPG processing module 544 information table or the EPG page acquires CRID digital television broadcast program currently received from the program description, and terminal-side location resolution module 543 in the IPTV broadband program location information of the CRID corresponding, reacquisition and show location pointed to by the broadband IPTV program content.

[0120] 在与图5、图6相对应的实际应用场景中,用户A可以在观看数字电视广播节目时进行时移操作,进行时移操作时会进入到宽带模式以接收之前的数字电视广播节目所对应的IPTV宽带节目。 [0120] shift operation at six practical scene graph corresponding to the user A may be carried out in FIG. 5 when viewing digital television broadcast program, will enter into the wideband mode to digital before receiving a television broadcast when the shifting operation when IPTV program corresponding to the broadband program. 用户可以在接收IPTV宽带节目时进行时移操作,还可以重新返回收看数字电视广播节目。 When the shifting operation may be performed upon receiving user broadband IPTV program can return to watch digital TV broadcasts. 上述场景的具体实现过程如下: Specific implementation scenario described above is as follows:
