Abstract
本发明涉及一种付费电视方法,其中用户通过节目时间表屏幕上的显示实现即兴购买的选择和确认。用户从该时间表上的对具体节目的选择随后通过电子管理报文(EMM)确认,所述报文专用于即兴订购。为了核准立即显示选定的节目,专用于即兴订购的EMM包含在附着于节目时间表显示的数据中。
Description
技术领域
本发明涉及一种付费电视的即兴订购方法。
技术背景
在观众或听众对视听传输中的具体节目进行选择的已知系统中,用户(以下称为订户)以二种方式选择付费节目:
1)订户打电话给订户管理中心从而订购产品例如电影或录制的体育事件。这种做法正越来越少地被采用;
2)订户接收例如通过卫星发送的数据流时一并接收以简要方式展示所提供的节目的节目网格,通过查看在诸如阴极射线屏幕或液晶屏幕的可视装置上显示的该网格方便地进行选择。该过程例如在美国专利5,038,211中说明。
现有技术在于发送一数据流,其包括:
特定编码或加密编码视频信息中的视频信息;
显示上述节目网格所需的信息;
权利检查消息,其说明订户访问某产品的必要特权,
各种用来管理用户概要的权利管理报文或EMM,一种特定类型的权利管理报文专用于即兴订购并且商业上通常称为IEMM。
存在的问题和订户要看到他已登记的订购所需要的总时间量有关。事实上该时间由以下构成:
a)从例如按下遥控器上和选择所需产品相关的按钮到按下最终确认按钮例如“OK”所需的时间,
b)订户接收下一个IEMM所需要的时间。
接收IEMM所需的时间取决于数据流上的通信量以及订户的数量。由于IEMM是一种特殊类型的EMM,它在EMM广播周期中传送。从而在所涉及的周期结束并且系统确认该即兴订购之前可能要经过一段订户觉得相当长的时间。当提供的产品相当多时,这段时间可以为数分钟。在这段时间期间,购买人不能应用他的控制并且在该产品可得到前可能会改变他的想法。
发明内容
本发明的目的是通过如下方法达到的,即本发明提供一种用于选择并确认对付费电视的即兴订购的方法,包括如下步骤:通过显示器向用户展示节目网格,用户利用自身知道的手段从该网格选择具体的节目,通过权利管理报文EMM确认该选择,其中该报文专用于即兴订购,该方法的特征在于,该专用于即兴订购的权利管理报文包含在捆绑到节目网格展示的数据中。
每次传输的适用于形成即兴订购体的节目网格通常包括:至少一个的传输名,通常带有对传输的描述,用户订购的价格,并且有时带有所谓的“等级”信息,尤其在电视观众必须为法律要求的观看或收听该传输的最小年龄的情况下。这些数据相捆绑以展示用于用户的节目网格。
通过使专用于有关传输的即兴订购的权利管理报文含有捆绑到所述网格的展示中的数据,有可能绕过现有技术中所需要的周期时间。
已经做出他的选择并且已按下确认即兴订购按钮的用户只需要等待系统结束广播权利管理报文的当前周期。这使得更为方便。
在本发明的一具体实施例中,在安装在用户的屋内的硬件组件中本地地使用该权利管理报文,该硬件组件包括一个在其中存储订户权限以及有关该用户的预订概要的微处理器。
该硬件组件例如采取读芯片卡机的形式,该芯片含有微处理器或芯片,而该读芯片机借助自身所知的手段可以读或解密该芯片卡。
在本发明的一具体实施例中,专用于即兴订购的权利管理报文具有引起二种通知的可能:一方面批准观看,而另一方面否决该权限。这种可能在管理用户做出的预订上提供了附加的灵活性。
附图说明
通过下述的并且参照附图的详细说明可以更好地理解本发明,附图中:
图1示出依据现有技术的用来构成节目网格的数据流,
图2示出依据现有技术的含有权利报文的数据流,
图3示出依据本发明的组合着用于节目网格的信息和权利报文的数据流。
具体实施方式
图1中示出现有技术中周知的并由包组成的流SI,每个包专用于传输。一旦解释时该包定义节目网格中的一行。
一个包为此含有日期D和时间T信息以及用于所提议的传输的描述符Des。该包关联着一个参照Ref,该参照Ref允许系统在用户选出的行和含有必要权限的权利报文EMM之间做出链接。
图2中示出该EMM报文,它包含用于链接SI流的报文和EMM报文的标识符Ref。它含有预订项Msg,Msg允许安全模块(通常为芯片卡)存储译码相关传输所需的数据。
依据本发明,图3示出一种有可能构成节目网格的新报文S1,其包括正文信息,例如日期D、时间T和对传输Des的描述,以及权利报文Msg。
当用户指示时,立即把权利数据Msg发送到安全模块,这使得有可能若满足信用和权限条件则从订购的传输获利。
请注意,依据本发明的一种变型,可以把描述报文Msg分为订购条件部分,例如订购价格和另外的订购取消条件部分。例如若一已订购某传输的用户在该传输开始后五分钟内决定不观看它,这是取消条件,可以申请取消并且根据广播商决定的策略可能偿还一部分金额。
在下面的详细说明中,所取的例子具有多个编码器,每个编码器接收一个模拟声频或视频流并恢复一个压缩数字化流。接着这些压缩数字化流的每一个进入一个通常简写成MUX的多路复用器,MUX还处理一个共用于所有压缩数字化流称为EMM的权利管理报文流,数个权利检查报文流、一个称为业务信息或SI的流以及一个称为PSI的节目专用信息流。
简单地把PSI流和称为PID的包标识符号(其中这些包是由该多路复用器生成的)一起提供给位于广播信道另一端例如卫星处的各译码器。
这样,作为例子,第一包将备有一个携带其编号的PID标题并且承载着来自“Suisse Romande 1”电视台的传输的视频流成分。下一个承载着另一个PID标题的包例如承载着来自“Suisse Romande 2”电视台的声频流成分。第三包在它的PID后面可能承载着来自“Suisse Romande1”电视台的声频流成分,并依此类推。
严格地说,PSI流不含有所谓的可理解的信息,例如台名。它仅仅给出提供给入口译码器的PID号,从而向它提供阿里安娜电信(Arianewire)并且允许它通过无错误对接重建包串。
而SI业务信息流的作用是传送用于填入节目网格的必要数据。一般来讲,这些数据是所谓的可理解的数据。实际上,它们显式地提供台名(例如上面的例子中的TSR1和TSR2),给出所有传送的频率列表,或者至少给出所有传输的列表,该列举是不受限制的。
临时地组织节目网格。实际上把业余信息流中含有的信息排列成时间段。第一段例如可能占据从午夜到4am的时隙,而下一段占据从4am开始的另一个时隙。节目网格按称为描述符的格式布置信息。这些描述符是标准化的并且记录节目名,类型(体育、信息、儿童节目等),开始时间,持续时间等,该列出是不受限制的。
本专利申请还延伸到一种特别用来接收专用于相关传输的即兴订购的权利管理报文的描述符。从而在无须等待权利管理报文的周期的结束的情况下下,用户在直接读了和该描述符对应的字段后的对他的传输选择的确认允许在管理订户的系统中记录该订购。
此刻译码器把权利报文中含有的信息发送到芯片卡,该芯片卡着手进行检查必需的权限准则(例如信用准则)并会存储对应的权限。该权限是按预订对待的,也就是说它核准随后对选定传输进行的译码。
从该例可以看出专用于即兴订购的权利管理报文和业务信息一起编码并且存储在节目网格中,而不是在和常规权利管理报文对应的周期的后面。
在实现本发明的形式中的一种中,和IEMM报文一起发送传输价格。从而,通过该报文管理的不仅有权限还有它的金额,在从订户的卡订购的事件下可以记入该金额。这使得有可能采纳一种随传输类型不同而不同的价格政策。
