Abstract
在多个地点具有显示设备(121-12n)的家庭多媒体网络(10、100),可以向用户提供在一个地点暂停对先前记录的内容的重放并稍后在另一地点继续内容重放的能力。为了防止继续重放不适合于某些地点(例如,儿童的卧室)的内容,所述家庭多媒体网络有利地通过建立能够接收所暂停的先前记录的内容的许可地点的列表来向用户提供限制所选地点进行继续重放的能力。
Description
技术领域
本发明涉及一种用于控制对于在多个地点重放的内容的访问的技术。
背景技术
视频内容的传送已经从在特定的时间发送一组固定的现有节目发展到在任何时间提供可供下载的视频内容。记录技术的进步已经在很大程度上实现了在任何时间传送内容。能够存储大量视频内容的数字化、非线性的记录设备(硬盘驱动器)的发展,以及例如MPEG-2和现在的H.264的视频压缩标准的发展使得能够传输和记录全长度的影片和其他类型的视听节目来用于在任何时间传送。
许多视频内容的供应商,例如有线电视和卫星电视提供商,现在提供具有内置的记录设备的机顶盒,从而允许用户记录用于稍后观看的节目。一些视频内容提供商还为用户提供在该提供商的网络内将内容记录在记录设备上的能力,通常被称为“基于网络的记录”。用户还可以将内容记录在外部记录设备上,例如个人计算机、移动电话,以及通过机顶盒来播放的其他这种设备上。
除了向用户提供记录内容的能力,很多内容提供商现在为用户提供在例如家庭的公共建筑物内的多个地点之间共享内容的能力。机顶盒的这个内容共享能力允许它充当“全屋”(whole-house)设备,产生例如暂停-转移-取消暂停的功能,所述暂停-转移-取消暂停的功能允许用户在一个地点开始观看一个节目,然后暂停该节目,并且稍后取消暂停该节目来用于在另一个地点重放。目前,与全屋机顶盒相关联的暂停-转移-取消暂停的功能允许任何用户在任何地点取消暂停该节目以观看。假设该全屋机顶盒允许移动设备的无线访问,这样的移动设备的用户也可以在任何地点取消暂停该内容。
在某些情况下,用于使用所述暂停-转移-取消暂停功能来多地点观看的现有的所记录的内容可能不适合全家所有成员观看。例如,含有成人内容的电影可能不适合年幼的儿童观看。然而,提供暂停-转移-取消暂停功能的当今的机顶盒缺乏在特定地点防止取消暂停内容的家长控制。
一些内容提供商向用户提供基于与该内容相关联的评级来限制观看的能力。例如,电影通常具有下列评级之一:G(一般观众)、PG(建议家长指导)PG-13(建议家长指导,但不适于不到13岁的儿童)和R(限制级)。然而,这样的评级并不总是可以作为儿童观看可取性的很好的指标。不具有任何评级的内容可能包含只适合成人的话题。防止取消暂停所有未评级的内容一般不能提供可行的解决方案。许多儿童节目缺乏内容评级,因此不能由儿童在没有密码的情况下取消暂停。当内容提供商允许通过移动设备对内容取消暂停时存在同样的问题,因为许多家庭成员会可以拥有这样的设备。
因此,存在对于用于控制多地点数字视频记录器的访问的技术的需求。
发明内容
简单地说,根据本原理的优选实施例,一种控制在公共建筑物内的多个地点访问记录的内容的方法通过响应于在一个地点开始重放先前在另一地点被暂停的记录的内容的取消暂停命令来确定所述一个地点是否被授权接收内容开始。如果是这样,在所述一个地点开始重放暂停的记录的内容。
附图说明
图1图示了按照本原理的适于实施记录设备访问控制技术的相连接的显示设备的第一示例性网络的示意性框图;
图2图示了按照本原理的适于实施记录设备访问控制技术的相连接的显示设备的第二示例性网络的示意性框图;以及
图3以流程图示出用于建立在不同的地点访问记录的内容的权限的方法的步骤。
具体实施方式
图1图示了用于将通常以视听节目的形式(例如,电影和电视节目)的内容发送至多个视听显示设备(例如,电视机)121-12n的第一示例性网络10的方框示意图,其中n是大于零的整数。通常,显示设备121-12n中的每一个存在于公共建筑物内的不同地点。例如,每个显示设备通常存在于家中不同的房间内。
网络10包括主内容选择设备14,它通常是以具有例如硬盘等的相关联的记录设备16的机顶盒的形式,所述相关联的记录设备16内置在机顶盒内或在机顶盒外部。在实践中,主机顶盒14从例如有线或卫星电视提供商的网络服务提供商接收视听内容。主机顶盒14将内容传送到相关联的显示设备,例如,显示设备121。此外,主机顶盒14具有将内容传送到例如从属机顶盒181的一个或多个从属机顶盒的能力。在实践中,主和从属机顶盒使用由多媒体电缆联盟(MoCA)建立的家庭多媒体网络标准以允许在设备之间共享内容。也可使用允许在例如机顶盒的内容选择设备之间共享内容的其他网络标准。
正如主机顶盒14向相应的显示设备(例如,显示设备121)传送内容那样,每个从属机顶盒同样地用作将内容传送到相应的显示设备。因此,例如,从属机顶盒181将内容传送至显示设备122。在某些情况下,显示设备,例如显示设备12n将具备所需的结构和功能以避免需要如图1中用虚线示出的从属机顶盒所表示的从属机顶盒。在这种情况下,显示设备12n将直接从主机顶盒14接收内容,而不是通过从属机顶盒。从主机顶盒14向从属机顶盒,例如从属机顶盒181的内容发送通常发生在同轴电缆上,虽然其他有线或无线的通信链路也可用作这个功能。
在例如图1的网络10的通常的家庭多媒体网络中,主机顶盒14允许用户暂停重放在第一显示设备上显示的先前记录的内容,并且,此后,在另一显示设备上继续(即,取消暂停)内容重放。通常,用户通过经由遥控器20向与显示设备相关联的主机顶盒14输入适当的命令来在该显示设备121上暂停内容重放。此后,用户将经由遥控器(未示出)来向例如从属机顶盒181的一个从属机顶盒输入适当的命令以在家中另一地点的显示设备122上取消暂停(例如,继续)重放记录的内容。用语“暂停-转移-取消暂停”经常用作对于在一个地点暂停内容重放,并且稍后在另一地点继续重放的过程的简短描述。
图2图示了用于将内容传送至多个视听显示设备121-12n(例如,电视机)的家庭多媒体网络100第二示例性实施例的方框示意图。网络100包括耦接在内容提供商网络的头端150的网关140。网关140从头端150接收内容并将内容发送至多个内容选择设备,通常是机顶盒1801-180n(其中n是整数)中的每一个。每个机顶盒向电视机121-12n中的相应一个提供内容。
与图1的网络10不同,图2的网络100没有记录设备。相反,由内容服务提供商供给的头端150通常包括响应于从网络100接收的命令来记录和重播内容的一个或多个记录设备160。特别地,用户可以经由一个遥控器190来向经由网关140向头端150发送的机顶盒1801-180n中的一个输入适当的命令以开始记录或重放内容。类似图1的网络10,网络100允许暂停在第一显示设备121上正在显示的内容并在第二显示设备12n上继续显示。换句话说,图2的网络100像图1的网络10那样具有暂停-转移-取消暂停的功能。通常,用户通过经由遥控器190向机顶盒之一输入适当的命令来暂停或取消暂停在图2的网络100中的内容重放。机顶盒1801-180n以及网关140还可以响应于通过其他设备,例如移动设备200、例如手机、个人数字助理或例如具有无线功能的输入板设备所输入的暂停命令。根据无线连接的性质,用户可以使用他的/她的来自远程地点的移动设备200来在家庭内的某一地点取消暂停内容。
在一个地点的显示设备上暂停重放内容并在另一地点的显示设备上继续重放的能力可以相对于内容的性质和那些能够在给定地点开始重放的个人被证明是有问题的。例如,家长可以在第一地点(例如,书房)开始重放具有成人主题的内容,并且此后在一旦该家长进入主卧后继续重放的意图下暂停该内容。然而,现今家庭多媒体网络中现有的暂停-转移-取消暂停的功能允许用户在该网络服务的任何地点取消暂停内容。
根据本原理,图1的网络10和图2的网络100向用户提供了限制用户可从中开始继续内容重放的地点的能力。图3以流程图形式示出了方法300的步骤,通过该方法300用户可建立那些用户可继续(例如,取消暂停)内容的重放的地点处的设备(例如,机顶盒或显示设备)的权限。该方法300开始于步骤302,此时用户将启动暂停命令以禁止内容的重放。此后,用户将启动命令来获取具有显示设备的地点的菜单,在所述设备上在接收到取消暂停命令后内容可被重放。在步骤304中,用户将权限授予那些与允许对内容取消暂停的地点相关联的设备(例如机顶盒)。用户可以通过滚动来查看地点列表。因此,例如,用户可对主卧中的机顶盒授予权限,但不对客厅或儿童卧室内的机顶盒授予权限。此外,用户可对某些移动设备而不对其他设备授予权限。相似地,用户可以排除设备以使它们在没有密码或个人识别码的情况下明确地不能取消暂停内容。一旦用户选择了具有取消暂停内容的权限的那些设备,然后,在步骤304中在这样的设备收到取消暂停命令后,内容重放会发生。
图3的步骤方法300可以包括附加的改进。例如,在步骤302中在用户给予权限之前,可以发生用户身份验证,要求输入密码或个人识别码(PIN)。此外,图3的步骤方法可以在即使没有用户输入的情况下,根据一天中的时间或与内容相关联的评级来自动排除某些地点。例如,在晚上的某一时间后,可能被儿童占用的任何地点,例如儿童的卧室或客厅会自动没有取消暂停内容的权限。此外,在步骤302期间所给予的权限也可以包括与地点无关的设备。例如,用户可以对移动设备(例如,儿童的手机)授予或拒绝给予取消暂停内容重放的权限。
上面描述了一种用于在多个地点控制对内容重放的访问的技术。
