Abstract
一种用于接收内容(12)的装置(10)包括一个存储器(2),用于存储描述符,以及一个处理器(18),用于读取嵌入在该内容中的描述符以及源代码。该处理器(18)对描述符和源代码进行比较,当描述符与源代码实质上相同时,允许访问内容,例如在屏幕(20)上显示内容。该描述符表示该装置可用的区域,而该源代码表示广播内容(14)的源。另外,或作为选择,该描述符可以表示该装置可用的时区,并且源代码表示广播内容(14)的源时区。当包括在内容(14)中的内容代码与存储在该装置(10)的存储器(12)中的描述符不匹配时,该装置(10)阻止内容被访问,例如阻止显示。此外,使用规则可以被嵌入到该内容(14)中,并且该处理器(18)被设置为读取该使用规则,并根据该使用规则来允许内容的访问。
Description
本发明涉及根据区域和使用规则允许在一个介质上显示内容。更具体地,根据使用规则,允许源内容被显示在一个屏幕上,例如,如果在源内容和显示设备中检测到相同的区域代码。
通常,可以不受限制地观看电视广播。广播内容可以是来自电视的数据,例如ATSC(美国电视标准委员会)电视广播流,无线电,卫星,或互联网例如网页,网络广播,走陆地,或卫星传播的DVB(数字视频广播)。为了增加收入,广播公司迫切希望能够控制观众收看节目的时间和地点。因此,就需要控制能够收看广播内容的时间和地点。
根据本发明,一种用于接收内容的装置,包括一个存储器,其中存储有描述符;以及一个处理器,用于读出描述符和嵌入在该内容中的源代码。该处理器对描述符和源代码进行比较,并且当描述符实质上等同于源代码时和/或根据嵌入在访问内容中的使用规则,允许对内容进行访问,例如在屏幕上显示。该描述符表示装置可以被使用的区域,而源代码表示内容广播的区域。另外,或作为选择,该描述符可以表示装置能够使用的时区,而源代码包括内容广播的时区。当嵌入在时区中的内容与包括在装置中的时区不匹配时,该装置就不允许对该内容进行访问。
本发明的进一步的特征和优点将会随着下面参照附图对说明书的详细描述而变得更加清楚,该附图指出以及示出了本发明的一个优选实施例;其中:
图1中示出了根据本发明的接收器。
参照下面通过附图对本发明优选实施例的详细说明,本发明及其优点将会变得更加易于理解。
这里描述一种用于接收内容的装置和方法,其中只有当满足某些特定的条件,例如在具有嵌入在装置中具有相同或实质上相同的区域代码以及接收到的内容之后,才允许访问内容,比如在屏幕上显示内容或将内容提供给扬声器。
区域代码可以被嵌入到内容中,而该内容可以是来自任何源的数据流,例如广播,电视,互联网,或者被提供在任何存储产品上,例如磁带,CD(光盘),DVD,固态存储器或者任何其它已知的存储装置,或者它们的组合。该内容可以通过任何装置或介质来发送,例如通过空间,包括卫星或者任何长程或短程的无线传输系统;有线传播,例如包括光纤的电缆。
在下面的说明中,为了能够彻底的理解本发明,列出了多个具体细节,例如具体类型的介质和内容。但是,对于本领域内的技术人员来说显而易见的是,本发明的实现并不依赖于这些具体的细节。在其他的情况下,为了避免不必要的模糊本发明,并没有详细的说明公知的系统。
在这里所描述的说明性实施例中,本发明应用于一个电视接收器,其中内容包括电视信号,例如节目或电影。然而,本领域内的技术人员能够认可的是,接收装置和内容可以是任何其它的接收装置和内容,例如磁带或盘或任何存储介质的重放装置,广播或互联网装置和内容,其中该内容可以是任何类型的数据或信号,例如在美国专利申请No.09/471750以及国际发布No.WO0149030中公开的信号,它们在这里整体上一并引用作为参考,并且公开了与一个存储在媒介系统的数据结构中的区域信息一块表示收费系统。该信号或数据可以来自任何源并且通过任何装置或介质来发送,例如通过互联网或电视和广播信号来发送的视频或音频流。
在图1所示的实施例中,提供一个接收设备10用于接收和重放内容。该接收设备10可以是具有任何调谐器的任何类型的接收器,例如广播和电视调谐器,如ATSC或DVB调谐器。另外,或作为选择,接收设备10可以是任何类型的重播装置,例如磁带和光学DVD或CD重播装置。示意性的,该接收设备10是一个具有调谐器的电视接收器,其被调制为接收ATSC电视广播流。为了简洁起见,接收装置10中不是与本发明直接相关的细节,例如调谐器,接收装置以及其它电路并没有被包括在其中,但是它们都是本领域内所公知的。
该电视接收器10包括一个存储器,例如在制造该存储器的时候,至少一个描述符或区域代码被存储在其中,该描述符或区域代码可以是一个区域,例如美国或欧洲。用户无法写入或改变存储在存储器12中的数据,并因此也无法在其中修改或存储新的描述符或区域代码。另外或候选的描述符可以位于电视接收器10中,例如时区,如美国的太平洋,中部,山地或东部时区。该电视接收器10被设置为从源16,例如ATSC电视广播流接收内容14,其中该流具有至少一个嵌入在其中的描述符或源代码。该电视接收器10包括一个处理器18,该处理器经配置用来读取被装入电视存储器12中的描述符,以及嵌入在内容14中的源代码。当电视10的描述符实质上等同于内容14的源代码时,该处理器18允许访问内容,例如在屏幕上显示内容。
根据本发明,至少一个区域代码被嵌入在内容14中。例如,在说明性的例子中,该内容为美国的广播电视信号,一个描述符,例如至少一个表示广播内容的源的区域代码被加入到ATSC(美国电视标准委员会)电视广播流中。该描述符可以被加入到任何信号或内容,例如已经存在的或新的高清晰视频广播信号中。这种典型的信号就是具有包括用于所有广播通道的音频和视频内容的数据包,以及描述如何将信号解调(或分解)为可视视频的数据包。该信号可以包括嵌入在其中的指示性数据包,例如广播信号的播放时间,以及描述、帮助使用内容的节目引导信息。
该已经被嵌入在广播节目中的指示性数据包可以被扩展为包括区域代码或其它描述符,例如广播节目源的时区和/或广播节目的时间,以及用于访问内容及控制的使用规则,例如防止拷贝等。另外,或作为选择,所希望的描述符可以包括在被加到广播上的新的数据包中。该内容描述符可以由接收者10使用,其被设置为确定该内容是否可以被查看、复制或者转发。
因此,该ATSC电视广播节目流例如可以包括描述符,其中该描述符表示内容14的广播原始区域,广播源的时区,和/或内容14的广播时间,例如最近一小时的附近以及使用规则。也可以包括其它的描述符,用于允许和/或防止通过使用适当配置的接收器来查看,重现,重播和/或记录,其中该接收器可以是,例如电视接收器10,以及特定驱动器和磁盘,其在美国专利申请No.60432889(美国临时专利申请No.60372893,代理人号No.US020116)中公开,名称为“RecordingAllowance Based on Regions”,作者为Raymond Krasinski,其也是本发明的发明人,其中实质上相同的描述符也可以被包括在用于比较和允许内容重现的装置存储器和磁盘中。示意性的,这些描述符类似于那些已经被装入数字电视广播数据流中,因此不会影响数字电视广播的服务质量。
将电视接收器10的处理器18设置为在允许访问内容14之前,读出并比较嵌入在内容14与嵌入在接收器10中的描述符,并当内容描述符和装置描述符实质上相同时,允许内容访问,例如在屏幕20上显示内容14。作为选择,该处理器18根据嵌入在内容14中的使用规则来允许内容显示。例如,根据嵌入在该内容14以及接收器10中的区域代码和/或时区,该使用规则可以指示从由接收器10的定时模块22提供的当前时间经过一个预定时间之后允许进行内容显示。为了防止用户的篡改,可以周期性地或随机地从广播内容或具有时间和数据信息的其它信号中提取当前时间和时区,例如通过全球定位卫星信号。
在接收器中的广播内容以及装置描述符中增加或嵌入内容描述符以及使用规则,并且设置接收器,使之能够读出并比较内容和装置描述符以及使用规则,并允许根据内容和装置描述符和/或使用规则来访问内容提供了一个系统和方法,其允许对广播内容在转播区域之外的收视和复制保护进行控制。
最后,上述的内容仅仅对本发明进行了示例性的说明,而不应该被解释为将所附的权利要求限制为特定的实施例或实施例组。例如,处理器22可以是专用处理器,用于根据本发明进行处理,或者也可以是通用处理器,其中仅仅运行众多功能中的一个以根据本发明进行处理。该处理器可以利用程序的一个部分,多个程序段来运行,或者可以是利用专用或多用途集成电路的硬件装置。用于允许内容重现的上述系统可以与其它的系统相结合使用。这样,虽然参照特定的具体实施例对本发明进行了详细的描述,但是应该可以理解的是,在不脱离本发明下面的权利要求的精神和范畴的情况下可以进行多种修改和变化。该说明书和附图因此被视为一种示意性说明的方式,而不是要限制所附权利要求的范围。
在解释所附权利要求的过程中,应该理解的是:
“包括”一词并不排除出现除了给出的权利要求中列出的元件或动作以外的其它元件或动作;
元件之前的“一个”一词不排除出现多个这种元件;
权利要求中的任何参考标记不会限制它们的范围;
多个“装置”可以由相同项或硬件或软件实现结构或功能来表示;以及
每个公开的元件都可以由硬件部分(例如离散电子电路),软件部分(例如计算机程序),或者它们的任何组合来构成。
