在步骤230，示范性方法200可以包括确定电视用户所指向的屏幕指针位置。步骤230可以包括以各种方式中的任意一种来确定屏幕指针的位置，下面将给出这些方式的非限制性例子。在美国临时专利申请No.61/242,234中给出了屏幕指针位置确定过程的各种非限制性例子，本文将其全部纳入参考。屏幕指针位置可以，例如，由屏幕中心坐标系(例如，x-y像素坐标)、屏幕独立坐标系(例如，基于动态图像间的位置，其中该位置通用于所有电视屏幕)、世界坐标和/或一般坐标系、基于视频帧的坐标系等来表示。
步骤230可以包括，例如，电视分析传感器信息(例如，与电视上和/或电视外的传感器相关)以确定用户屏幕指针位置。步骤230还可以包括，例如，电视从电视外部设备(例如，电视接收器、电视控制器、电视网络设备、用户指向设备等)接收描述屏幕指针位置的信息。
步骤230可以包括，例如，识别能暂时确定已知屏幕指针位置的时间戳。该时间戳可以，例如，通过时钟、嵌入视频流中的时间戳、嵌入包括对象信息的流中的时间戳、与用户指向设备发送的信号相关的时间戳等来获取。该时间戳的确定过程可以基于，例如，用户命令(例如，用户表示已经做了选择)或不用用户直接表明已经做了选择而自动进行(例如，系统确定用户已经指向一个对象至少一段时间了)等。该时间戳可以用于，例如，来确定对播放的电视节目中的动作、变化和/或暂时瞬态对象的选择。
总而言之，步骤230可以包括确定电视用户所指向的屏幕指针位置。相应地，除非明确说明，本发明的范围不受任意特点类型的屏幕指针位置或确定该屏幕指针位置的任意特点方式的限制。
在步骤240，示范性方法200可以包括识别播放的电视节目中的用户可选对象，该可选对象是用户至少在部分程度上根据已经确定的屏幕指针位置(例如，在步骤230确定的)来指向的。步骤240可以包括以各种方式中的任意一种来执行该识别过程，下面将给出这些方式的非限制性例子。
例如，步骤240可以包括确定播放的电视节目中的一个或多个用户可选对象(例如，或相关选择区域)的屏幕位置和/或尺寸，以及通过分析一个或多个用户可选对象各自的屏幕位置和已经确定的屏幕指针位置(例如，在特定的时间点和/或时间段)来识别用户选择的对象，以确定用户选择的电视节目对象。例如，该屏幕位置可以包括与用户可选对象的各自位置相关的一个或多个点、区域和/或体积的屏幕位置。
在这种示范性例子或任意包含确定播放的电视节目中一个或多个对象屏幕位置的例子中，步骤240可以包括，例如，以各种方式中的任意一种确定该屏幕对象位置。例如，步骤240可以包括接收用于识别和/或描述电视节目中的用户可选对象的信息。
例如，步骤240可以包括从与接收到的电视节目相同的资源中接收用于识别和/或描述该用户可选对象的信息。例如，步骤240可以包括接收嵌入与播放的电视节目的通信流相同的数据流中的信息(例如，嵌入接收到的电视栏目数据中)。例如，电视流协议可以包括具体化元素(和/或使用未分配元素)，该元素包括与可选对象相关的信息(例如，对象特征、形状、位置、大小、颜色、运动特性、时序、出现的时间窗口等)。
又例如，步骤240可以包括接收与播放的电视节目的通信流并行通信的数据流中的用于识别和/或描述用户可选对象的信息。在该例子中，电视栏目流和对象信息流可以从同一资源通过同一电视节目通信信道接收。又例如，步骤240可以包括从相同资源但通过与接收电视节目不同的通信信道和/或与电视节目通信信道不同类型的通信信道来接收该信息。
进一步例如，步骤240可以包括从与接收电视节目不同的资源(例如，第三方信息供应商、电视网络资源等)接收用于识别和/或描述该用户可选对象的信息。在该示范性例子中，步骤240可以包括通过各不相同的通信网络或通过一个或多个相同的通信网络接收该信息。又例如，步骤240可以包括通过与接收电视节目的媒介不同的通信媒介来接收该信息。
步骤240可以包括，例如，接收数据流中的用于识别和/或描述用户可选对象的信息，该数据流通常用于传送这种信息(例如，无论是否由用户和/或其它系统请求)。另举一例，步骤240可以包括仅在请求的时候(例如，仅当电视、电视控制器、电视接收器、用户电子设备、用户等请求时)传送该信息(例如，向电视)。
步骤240可以包括，例如，实时接收用于识别和/或描述该用户可选对象的信息(例如，在接收电视节目时)。又例如，步骤240可以包括从用户存储的电视节目资源中接收该信息。例如，这种信息可以与存储的电视节目一起存储在用户存储设备(例如，同一数据文件、单独但相关的文件等)中。在该示范性实施例中，可以从用户电视节目存储设备中与电视节目同步接收这种信息。
如上所述，用于识别和/或描述电视节目中的用户可选对象的信息可以包括与该可选对象相关的时间信息。例如，可选对象的运动可以表示为时间函数。又例如，电视节目中出现的可选对象可以与该对象出现的时间窗口相关。与用户屏幕指向(或对象选择)事件相关的计时可以与播放的栏目中的可选对象位置的计时同步，以确定用户是否在特定时间指向(或选择)特定位置的特定对象，这将在下面进行详细描述。
用于识别和/或描述电视节目中的用户可选对象的信息可以包括用于定义与播放的电视节目中的各个用户可选对象相关的在播放的电视节目中的各自区域的信息。例如，该信息可以包括用于描述与各个用户可选对象相关的各自的几何形状(例如，二维和/或三维几何构架)的信息。例如，可以是与用户可选对象相关的圆形、椭圆形、正方形、长方形、五边形或任意多边形。用户对于这些几何形状其中之一的选择(例如，在相关时间点该几何形状范围内已确定的屏幕指针位置)可以表明用户对相应对象的选择。
如上所述，对该对象的描述(无论是否几何形状)可以包括用于描述与该用户可选对象相关的运动、外表、大小变化、形状变化等的信息(例如，时间上的信息)。例如，在用许多几何形状来描述用户可选对象(和/或与该对象相关的用户可选区域)的示范性场景中，对该用户可选对象的描述可以包括用于描述各个对象在节目中的运动方式(例如，以时间的函数、以视频帧编号的函数等)的信息和/或用于描述各个对象的尺寸变化方式的信息。
如果知道了屏幕指针位置和对象位置(例如，在特定时间点)，就可以处理这些信息来确定用户所指向的用户可选对象。如上所述，该处理过程可以包括确定与各个用户可选对象相关的电视屏幕区域和/或电视节目帧区域，该区域与用户所指向的屏幕指针位置相对应(例如，在特定时间点或特定时间段)。
在执行该处理过程时，步骤240可以包括低通过滤已确定的屏幕指针位置(例如，在步骤230中确定的)以补偿指针位置的意外偏移(例如，由抖动的或不稳定的用户指向造成的)，因此，增加了对象选择确定过程的可靠性。例如，对电视节目对象的成功用户选择要求用户在特定的一段时间(或特定数量的帧)内指向屏幕对象。
注意该低通过滤过程还可以在步骤后230执行。该过滤过程可以包括，例如，在特定的一段时间、特定数目的屏幕指针方向确定过程、特定数目的电视节目帧等内过滤。该过滤过程可以包括取许多屏幕指针方向确定过程的平均值、利用有限脉冲响应过滤方法等。
步骤240还可以包括，例如，通过识别最有可能的用户所选对象来确定用户选择的对象。例如，步骤240可以包括识别与步骤230中确定的屏幕指针位置最近的用户可选对象位置。又例如，步骤240可以包括至少在部分程度上根据用户可选对象各自的受欢迎度(例如，偏爱最常选择的无生命和/或有生命的对象)来确定最有可能的用户所选对象。又例如，步骤240可以包括至少在部分程度上根据金钱因素识别最有可能的用户所选对象(例如，将与付钱较多的广告客户相关的用户可选对象设置更高的可能性、将与基于每一次选择的广告费相关的用户可选对象设置更高的可能性等)。进一步例如，步骤240可以包括根据特定用户的选择历史来识别最有可能的用户所选节目对象(例如，特定用户最常选择的偏爱类型的对象)。又例如，步骤240可以包括根据对象的新奇度来识别最有可能的用户所选节目对象(例如，一个新对象可能比已经出现相对较长时间的对象吸引更多兴趣)。另外，例如，步骤240可以包括根据对象大小识别最有可能的用户所选电视节目对象。
选定的对象可以由独特的标识符识别(例如，对独特对象、对独特的相关对象组等)。因此，步骤240可以包括确定与已知用户所选对象相关的标识符。然后可以将该标识符用于各种进一步功能中的任意一种，下面将给出非限制性例子。例如，用于识别和/或描述用户可选对象的信息可以包括用于描述与该对象相关的功能(例如，信息展示功能、通信功能、商业交易功能、用户互动功能等)的信息。
示范性方法200的步骤(或其方面)可以，例如，实时执行(例如，由电视)。以这种方式，用户可以相对迅速地访问与用户所选对象相关的功能。又例如，示范性方法200(或其方面)可以以离线方式执行，在该方式中，与用户所选对象相关的功能将在以后提供给用户(例如，在电视栏目播放后、在用户暂停播放电视栏目时、在用户进入用户计算机系统时、在用户访问电子邮件时等)。
如上所述，示范性方法200的任意或所有步骤可以用于用户在节目实时广播时对电视节目中的对象进行选择和/或可以用于用户以时移方式对录制在用户(或家用)电视节目录像机(例如，个人录像机(PVR)、录像机(VCR)等)中并正在向用户播放(例如，步骤220)的电视节目中的对象进行选择。例如，用户可以将广播电视节目录制在PVR上以便以后观看，在以后观看该录制的节目，以及在以后观看该时移电视节目时，在该节目中选择用户可选对象。
类似地，示范性方法200的任意或所有步骤可以用于用户对物理存储媒介(例如，在DVD、录影带、非易失性存储设备等)提供给用户(或由用户存储)的电视节目中的对象进行选择。例如，用户可以购买包含所有电视剧集的一套DVD，在自己方便的时候观看每一集，以及在观看该剧集时，选择该节目中的用户可选对象。
在用特定时间点的屏幕指针位置来确定对象选择的示范性场景中，可以使用各种时间参考中的任意一种。例如，屏幕指针位置与用户可选对象位置(例如，屏幕和/或帧内对象位置)的同步性可以基于播放时间戳(PTS)和/或解码时间戳(DTS)，或者其它类似地能在广播和/或录制的节目中编码的时间参考或被确定为正在向用户播放的节目。在该场景中，只要对象位置和指向确定过程基于通用和/或同步时间参考，所指向对象的识别就可以精确执行。
如上所述，用于识别和/或描述用户可选对象的信息可以从视频节目流中的编码或单独流(和/或信道)中接收。在存储电视节目信息(无论短期或长期)的场景中，对象信息也可以存储(例如，与存储的节目信息在同一数据文件中、在单独但相关的数据文件中等)。以这种方式，当用户决定观看时移节目时，电视就可访问对象信息了。
或者，当需要时，第三方可以请求用于识别和/或描述节目中用户可选对象的信息。在另一实施例中，视频信息可以与电视分开解码(例如，在机顶盒、有线和/或卫星电视接收器、PVR等中)并提供给电视以供播放，该对象信息还可以通过这些分离的设备接收并提供给电视机(例如，在与视频驱动信号分离的信息信道中)。
注意尽管前面的描述有一部分涉及分析屏幕指针位置和屏幕对象位置来识别用户所选的对象，该分析过程还可以类似地通过分析帧指针位置和帧对象位置来执行。换言之，该分析过程可以包括进行各种坐标转换中的任意一种以便通过各种各不相同的坐标域中的任意一种来执行该分析过程。
总而言之，步骤240可以包括识别播放的电视节目中用户所指向的用户可选对象(例如，至少部分程度上根据确定的屏幕指针位置(例如，步骤230中确定的))。相应地，除非明确说明，本发明的范围不受执行该识别的任意特定方式的限制。
例如在步骤295，示范性方法200可以包括继续执行操作。步骤295可以包括执行各种继续操作中的任意一种，下面将给出这些继续操作的非限制性例子。例如，步骤295可以包括返回执行前述任意方法步骤。例如，步骤295可以包括返回执行示范性方法200的步骤230来确定另外的屏幕指针位置和电视节目中的相应用户所选对象。
又例如，步骤295可以包括生成用于表明已确定的用户可选对象(例如，在步骤240中识别)的用户输出。例如，步骤295可以包括在播放的电视节目上覆盖与确定的用户可选对象相符的图形特征。例如，如上所述，用户可选对象(和/或用户可选对象的用户可选部分)可以由一个或多个几何形状定义。在该示范性场景中，步骤295可以包括在步骤240确定用户已经选择了与该几何形状相关的用户可选对象时，突出(highlight)该几何形状(或其边界)。又例如，步骤295可以包括在电视屏幕上显示已确定对象的轮廓、暂时照亮或改变已确定对象的颜色、暂时在屏幕上显示作为已确定对象的标识的信息等。步骤295还可以包括，例如，输出表明用户所选对象已确定的音频信息。
又例如，步骤295可以包括将用于表示已确定的用户可选对象的信息传送给电视机外部设备(例如，与电视在同一房屋的用户设备和/或通过通信网络与电视通信相连的设备)。例如，步骤295可以包括将该信息传送给电视机远程控制设备(例如，在电视机远程控制设备可以向用户提供已确定的用户可选对象的标识的场景中)。在该示范性场景中，电视机远程控制设备可以包括视频显示屏，在该视频显示屏上，可以显示电视栏目，并且可以用图形表示已确定的用户可选对象(例如，取代在电视屏幕上识别和/或在电视屏幕上识别之外)。
进一步例如，步骤295可以包括处理已确定的用户所选对象(例如，在步骤240中确定的)的信息以便确定根据该所选对象要执行的操作。在美国临时专利申请No.61/242,234中给出了这些操作的各种非限制性例子，本文将其全部纳入参考。
总而言之，步骤295可以包括执行继续的操作(例如，执行对应于用户所选电视节目对象的附加操作、为另一用户所选对象重复各种方法步骤等)。相应地，除非明确说明，本发明的范围不受继续处理过程的任意特定类型的限制。
