Description

提供广播内容信息的系统和在系统中提供广播服务的方法 Providing broadcast content information systems and methods for providing broadcasting services in the system

技术领域 FIELD

本发明通常涉及一种用于提供广播服务的系统和方法,具体地说涉及一种用于按顺序为广播服务器提供广播内容信息以提供关于当前广播的广播内容的准确信,t、的系统和方法。 The present invention relates generally to a system and method for providing broadcast services, particularly to a broadcast server for providing broadcast content to provide accurate information regarding the current broadcast channel of the broadcast content, t for the sequence, and the system method.

背景技术 Background technique

通常,通过普通家用电视(TV)和便携式终端向用户提供广播服务。 Typically, a broadcast service provided to a user through an ordinary household television (TV) and the portable terminal. 通过便携式终端接收广播服务的用户的数量已经大大增加。 The number of users receiving broadcast services through portable terminals has increased substantially. 移动TV服务是通过便携式终端提供的广播服务的示例,并且通常符合各种标准,例如,包括数字多媒体广播(DMB)、数字视频广播-手持(DVB-H)、开放移动联盟广播(OMA-BCAST )等。 Mobile TV service is an example of a broadcast service provided by the portable terminal, and usually comply with various standards, e.g., including a digital multimedia broadcasting (DMB), Digital Video Broadcasting - Handheld (DVB-H), Open Mobile Alliance Broadcast (OMA-BCAST )Wait. 在欧洲和美国以及南韩通常基于这种标准通过测试广播或正规广播向用户提供移动TV服务。 Usually provide mobile TV services to customers in Europe and the United States and South Korea based on this standard through testing or broadcast regular broadcasts. 除了现有广播中提供的视频/音频服务之外,包括现有数字TV服务的移动TV服务近来已经提供称为数据服务的新类型服务。 In addition to video / audio services provided in the existing broadcast, including the existing digital TV services offer mobile TV service has been recently a new type of service called data service.

现将参照图1描述用于提供广播服务的传统DVB-H系统。 Referring now to FIG 1 describes a conventional DVB-H system for providing broadcast services. 在图1中,内容提供单元102由内容提供者来管理,并且产生将由DVB-H 广播站广播的各种广播内容。 In Figure 1, the content providing unit 102 managed by the content provider, and generates various DVB-H broadcasting content broadcast by the broadcast station. 在此使用的内容是指通过根据可使用电子服务指南(ESG)或电子节目指南(EPG)组成的广播时间表的时间来区分的基本广播单位。 Content used herein refers to the basic broadcasting organization distinguished by the time of the broadcast schedule can be based on the use of electronic service guide (ESG) or Electronic Program Guide (EPG) composition. 当从内容提供单元102提供多媒体数据时,在对输入数据进行打包和复用之后,通信公司( common carrier )根据广播方法通过广播单元106 广播输入数据。 When the content providing unit 102 provides the multimedia data, after the input data is packed and multiplexed Communications (common carrier) broadcasting method according to the broadcast unit 106 broadcasts the input data. 换句话说,广播单元106通过互联网协议(IP)封装器(capsulator) 104对传输多媒体数据进行打包,通过复用器105对打包的多媒体数据进行复用,接着通过广播通信网络110广播复用的多媒体数据。 In other words, the broadcasting unit 106104 multimedia data transmission through the Internet Protocol (IP) encapsulator (capsulator) packed, multiplexed by the multiplexer 105 pairs packetized multimedia data, followed by the broadcast of the broadcast communication network 110 reuse multimedia data.

当从广播服务器100广播复用的多媒体数据时,用户的广播接收终端120 通过广播接收器121接收广播的多媒体数据。 When the multimedia data is multiplexed with the broadcast of the broadcast from the server 100, the user of the broadcast receiving terminal 121 receives the multimedia data 120 broadcast by the broadcast receiver. 通过包括在广播接收器121中的解复用器122和IP解封装器123对接收的多媒体数据进行解复用和解封装, Demultiplexing by the demultiplexer comprises a broadcast receiver 121 in the IP decapsulator 122 and 123 receive multimedia data and de-encapsulation,

从而将其重建为原始多媒体数据。 So as to be reconstructed into the original multimedia data. 接着将重建的多媒体数据输出到广播接收 Then outputs the reconstructed multimedia data to the broadcast receiving

终端120的多媒体处理器124以进行处理,从而可输出与用户选择的频道相应的广播。 Terminal 120 for processing a multimedia processor 124, so as to be output to the user corresponding to the selected broadcast channel.

在提供广播服务的系统中,广播服务器将广播服务信息(诸如每个频道中提供的服务类型和细节以及用于接收广播服务的接收信息)发送到广播接收终端120。 In the system providing a broadcast service, the broadcasting service information broadcast server (such as the type and details of the service provided in each channel and for receiving a broadcast service reception information) is transmitted to the broadcast receiving terminal 120. 所述广播服务信息在DMB的情况下可以是电子节目指南(EPG), 在DVB-H的情况下可以是电子服务指南(ESG)。 The broadcast service information in the case of the DMB may be an electronic program guide (EPG), in the case of DVB-H may be an electronic service guide (ESG).

接收广播服务信息的广播接收终端120预先存储广播服务信息。 Receiving broadcast service information 120 is previously stored broadcast service information broadcast receiving terminal. 一旦为广播服务选择了预定广播频道,广播接收终端120就通过参照先前存储的广播服务信息通过选择的广播频道接收广播内容,并且提供广播内容。 Upon selection of the broadcast channel for the predetermined broadcast service, to the broadcast receiving terminal 120 through a previous broadcasting service information stored in the broadcast content received through the selected broadcast channel, and providing broadcast content reference. 换句话说,当提供广播服务时,可根据先前接收的广播服务信息识别将提供的广播内容。 In other words, when the broadcasting service is provided, according to the information for identifying the broadcast service previously received broadcast content will be provided.

同时,当前通过选择的广播频道广播的广播内容与根据先前接收的广播服务信息在当前时间点计划广播的广播内容可能彼此不同。 At the same time, by selecting the current broadcast content of broadcast channel with the broadcast service information previously received broadcast content may differ from each other in the current time point program broadcast. 在这种情况下, 根据观看当前通过用户选择的广播频道广播的广播内容信息的请求,广播接收终端120从先前接收的广播服务信息检查关于选择的广播频道的广播内容信息,并且提供广播内容信息。 In this case, the current through the viewing request, the broadcast receiving terminal the broadcast content information of the broadcast channel selected by the user 120 broadcast contents information on the selected broadcast channel broadcasting service information previously received from the check, and providing broadcast content information . 因此,可向用户提供与当前通过选择的广播频道广播的广播内容信息不同的广播内容信息。 Thus, the current broadcast content may be provided by the selected broadcast channel information of different broadcast content information to the user.

例如,假设根据先前接收的广播服务信息第一频道从下午8:00至下午9:00计划广播戏剧A,并且第一频道从下午9:00至下午10:00计划广播戏剧B,但是由于广播服务器100的一些广播延迟而改变了戏剧A的时间表,因此将广播戏剧A直到下午9:10,并且将从下午9:10至下午10:10广播戏剧B。 For example, assume that the first channel according to the broadcasting service information previously received from 8:00 pm to 9:00 pm broadcast program play A, and the first channel from 9:00 p.m. to 10:00 p.m. drama broadcast program B, but since the broadcast Some broadcast delay server 100 to change the timetable drama a, so a will broadcast the drama until 9:10 pm and from 9:10 pm to 10:10 pm broadcast drama B.

如果用户通过检查先前接收的广播服务信息确认戏剧B计划在第一频道从下午9:00开始,并因此选择第一频道以观看戏剧B,则用户可能观看戏剧A而不是戏剧B,并且提供的广播服务信息也是关于戏剧A的信息而不是关于用户希望的戏剧B的信息。 If a user by checking a previous broadcast service information received acknowledgment Plan B Theater from 9:00 pm on the first channel, the first channel and therefore choose to watch the drama B, the user may watch the drama A drama rather than B, and offer broadcast service information is information about a drama rather than information about the user wishes to play B's. 由于即使当前在第一频道上广播的广播内容是戏剧A,戏剧B也作为广播内容信息被提供,因此,不能向用户提供关于当前广播内容的准确信息。 Even when the broadcast content currently broadcasted on the first channel drama A, B are also provided as a drama broadcast content information, and therefore, can not provide accurate information regarding the current broadcast content to a user.

如果用户为戏剧B的保留记录设置关于将在第一频道从下午9:00至下午10:00广播的内容的保留记录,则广播接收终端120开始记录第一频道在下午9:00广播的内容,并且在下午10:00终止记录。 If the user is a reserved recording setting content 9:00 Drama B 120 starts recording of the reserved recording on the first channel will be from 9:00 p.m. to 10:00 p.m. broadcast content, the broadcast receiving terminal of the first broadcast channel in the afternoon and ends at 10:00 PM record. 然而,由于在第一频道在下 However, since the first channel next

午9:00广播戏剧A而不是戏剧B,而且戏剧B实际上是从下午9:10开始, 因此戏剧A的一部分也被记录。 Afternoon 9:00 broadcast drama A drama rather than B, and B is actually a drama from 9:10 pm, and therefore part of the drama A is also recorded. 此外,因为在下午10:00终止记录,所以与最后10分钟相应的戏剧B的一部分不能被记录。 Further, since recording terminates at 10:00 p.m., so the last 10 minutes of play corresponding part B can not be recorded.

用于提供付费服务的条件接收系统(CAS)将唯一权限标识符(ID)分配给加扰的频道的多媒体内容,以识别多媒体内容。 Offer paid services for conditional access system (CAS) will be a unique permission identifier (ID) assigned to the multimedia content channel scrambled to identify the multimedia content. 尽管具有CAS的终端能够识别多媒体内容,但是提供多媒体内容的服务器必须包括加扰模块,并且终端必须包括解扰模块。 Although CAS has a terminal can recognize the multimedia content, providing multimedia content server but must include a scrambling module, and the terminal must include a descrambling module. 此外,由于解扰所需的大计算量,因此在终端中引起了重负荷。 Further, since a large amount of calculation required for descrambling, thereby causing heavy load on the terminal.

如上所述,传统地,用户根据先前提供的广播服务信息来检查关于广播内容的信息,并且通过参照先前提供的广播服务信息设置关于希望的内容的保留记录,而实际上不识别广播内容。 As described above, conventionally, a user checks the broadcast service information according to the previously provided information on the broadcast content, and broadcasting service information is provided by reference to previously provided on the recording reservation of a desired content, in fact, does not recognize the broadcast content.

因此,如果先前提供的关于广播内容的信息与实际广播内容不同,则可能向用户提供错误信息,而不是关于实际广播内容的正确信息。 Therefore, if the information about the actual broadcast content broadcast content previously provided different, it may provide an error message to the user, instead of the correct information about the actual broadcast content. 此外,在保留记录中,除了期望的内容之外,用户还可能记录不期望的内容,导致存储器和功率的浪费,甚至导致记录期望的内容失败。 Further, in the record-keeping, in addition to the desired content, the user may also record undesirable content, resulting in wasted power and memory, and even lead to the failure record desired content.

尽管CAS能够识别内容,但是为了使具有CAS的终端识别多媒体内容, 服务器必须包括加扰模块,并且终端必须包括解扰模块。 Although CAS that identifies the contents, but in order to identify the multimedia content has the CAS terminal, the server must include a scrambling module, and the terminal must include a descrambling module. 此外,由于解扰所需的大计算量,因此在终端中引起了重负荷。 Further, since a large amount of calculation required for descrambling, thereby causing heavy load on the terminal. 此外,需要提供广播内容信息, 其中,能够提供关于当前广播的广播内容的准确信息。 In addition, the need to provide broadcast content information, which can provide accurate information about the current broadcast content broadcast.

当在步骤706与选择的广播内容相应的内容ID和分析的内容ID相同时, 控制器300进行到步骤708以开始记录。 When the same step, the controller 300 proceeds to step 706 to select broadcast content with the content ID corresponding to the content ID and analysis 708 to start recording. 否则,控制器300进行到步骤704 以便分析包括在接收的包中的内容ID来检查内容ID是否相同。 Otherwise, the controller 300 proceeds to step 704 to analyze the received packet includes content ID to check whether the same content ID. 在此使用的记录是指在存储器单元306中存储接收包的多媒体数据的操作。 As used herein, the recording operation of the storage means of the received packet in the memory unit 306 of the multimedia data. 可按预定间隔执行步骤706,以便检查与设置了保留记录的广播内容相应的内容ID和在步骤704分析的内容ID是否相同,从而减少用于包接收的功率。 Step 706 may be performed at predetermined intervals to check the reserved recording set broadcasting content corresponding to the content ID and the content ID 704 is the same as in the analysis step to reduce the power for receiving of the packet.

当控制器300在步骤708执行记录时,在步骤712,控制器300可分析包括在接收的包中的内容ID,并接着在步骤714检查与设置了保留记录的广播内容相应的内容ID和分析的内容ID是否相同。 When the controller 300 at step 708 recording is performed, at step 712, the controller 300 may analyze the content ID included in the received packet, and then checks at step 714 is provided to retain the recorded broadcast content corresponding to the content ID and Analysis content ID is the same. 换句话说,控制器300在记录期间连续确定包括在接收的包中的多媒体数据是否是设置了保留记录的多媒体数据。 In other words, the controller 300 continuously determines whether the multimedia data during recording comprises the received packet is provided to retain records multimedia data.

当在步骤714与选择的广播内容相应的内容ID和分析的内容ID相同时, 控制器300进行到步骤708以继续记录。 When the same, the controller 300 proceeds to step 708 to continue the record at step 714 with the content ID corresponding to the selected broadcast content ID and content analysis. 否则,控制器300进行到步骤716, 以检查包括在接收的包中的内容ID是否是与广播时间表中的另一广播内容相应的内容ID。 Otherwise, the controller 300 proceeds to step 716 to check whether the content ID included in the received packet is of another broadcast content corresponding to the broadcast schedule in Content ID.

当在步骤716包括在接收的包中的内容ID存在于广播时间表中时,控制器300终止记录。 When the step 716 includes a content ID in the received packet is present in the broadcast schedule, the controller 300 terminates the recording. 换句话说,如果与包括在接收的包中的内容ID相同的内容ID存在于广播时间表中,则控制器300确定用户设置了保留记录的广播内容的广播是否被终止。 In other words, if the same content included in the received packet ID of the content ID exists in the broadcast schedule, the controller 300 determines whether the user is provided a broadcast recording reserved broadcast content is terminated. 在这种情况下,包括在接收的包中的内容ID可以是与计划在当前记录的广播内容之后广播的广播内容相应的内容ID。 In this case, the content ID included in the received packet may be broadcast after the program currently recorded broadcast content corresponding to the content broadcast in Content ID.

当在步骤716包括在接收的包中的内容ID不存在于广播时间表中时,控制器300进行到(A)。 When the step 716 includes a content ID in the received packet does not exist in the broadcast schedule, the controller 300 proceeds to (A). 现将参照图7B描述(A)之后的处理。 Referring now to FIG 7B process (A) described later.

参照图7B,因为包括在接收的包中的内容ID不存在于广播时间表中, 所以控制器300进行到步骤718,在步骤718,控制器300暂停记录。 Referring to Figure 7B, since the content ID included in the received packet does not exist in the broadcast schedule, the controller 300 proceeds to step 718, at step 718, the controller 300 pauses the recording. 换句话说,由于包括在当前接收的包中的内容不存在于广播时间表中,并且可能是没有计划广播的临时广播(诸如紧急广播或广告广播),因此控制器300暂停记录。 In other words, due to the inclusion in the current contents of the received packet does not exist in the broadcast schedule, and may be a temporary broadcast no plans to broadcast (such as emergency broadcast advertising or broadcasting), the controller 300 pauses the recording. 当在记录选择的广播内容期间出现没有计划广播的临时广播(诸如紧急广播或广告广播)时,控制器300在选择的广播内容中间暂停记录,并接着从暂停部分的末端通过重新后续地记录选择的广播内容来执行后续记录。 When the temporary broadcast program is not broadcast (such as an emergency broadcast or advertising broadcast) occurs during recording the broadcast content selected, the controller 300 in the middle of the selected broadcast content to pause recording, and then suspended from the end portion of the subsequent recording by re-selection broadcast content to perform a follow-up record. 通过这种方式,可以仅记录与由用户设置了保留记录的广播内容相应的多媒体数据。 In this manner, it is possible to record only the broadcast content is provided to retain the corresponding multimedia data recorded by the user.

此后,在记录暂停状态中,控制器300在步骤720分析包括在接收的包中的内容ID,并且在步骤722检查与设置了保留记录的广播内容相应的内容ID与分析的内容ID是否相同。 Thereafter, in the recording pause state, the controller 300 analyzes the content ID included in the received packet at step 720, and step 722 checks the content ID set corresponding to the content ID and Analysis of recording reserved broadcast content is the same. 换句话说,在记录暂停状态中,控制器300 确定包括在接收的包中的多媒体数据是否是设置了保留记录的多媒体数据。 In other words, in the recording pause state, the controller 300 determines whether the multimedia data including the received packet is provided to retain records multimedia data. 可按预定间隔执行包括在接收的包中的内容ID的分析。 Analysis can be performed at predetermined intervals in the content ID included in the received packet. 换句话说,在本发明中,可按预定间隔执行而不是对每个数据执行这样的步骤:在没有实际记录接收的多媒体数据的情况下确定接收的多媒体数据是否经历保留记录,以减小终端的功耗。 In other words, in the present invention, the predetermined intervals may be performed instead of the step of each data: determining whether a received without receiving multimedia data is actually recorded multimedia data is subjected to the case where recording reservations, to reduce terminal power consumption.

当在步骤722与设置了保留记录的广播内容相应的内容ID和分析的内容ID相同时,控制器300进行到步骤724,以从暂停部分的末端通过重新后续地记录设置了保留记录的广播内容来执行后续记录,并接着进行到(C),以进行到图7A的步骤712。 When the same, the controller 300 in step 722 set the broadcast content ID and the content recording reservation corresponding to the content ID and the analysis of step 724, through the end portion of the suspension subsequently re-recording of broadcast content is provided to retain records performing the subsequent recording, and then proceeds to (C), to proceed to step 712 of FIG. 7A.
