- the playing device may download the playing schedule from the corresponding server, and obtain the playing time of the content that the user does not desire to view according to the playing schedule, and set a
- the playing time monitoring program monitors whether the current playing time of the content that the user does not desire to watch is currently monitored. When the playing time of the content that the user has not expected to view is currently detected, it is determined that the currently received first media stream includes the user's undesired Watched content.
- the third monitoring method is as follows:
- the playback device may compare the currently received video frame with the previous or previous multiple received video frames, calculate the correlation between the two, and determine whether the currently received video frame is the content that the user does not desire to view.
- the video frame is used to determine whether the currently received first media stream contains content that the user does not desire to view.
- the fourth monitoring method is as follows:
- the playback device may preset a video frame database, store a first video frame of the content that the user does not desire to view, and set a video frame matching program to match the currently received video frame with the first video frame.
- the currently received video frame is the same as the first video frame, it is determined that the currently received first media stream includes content that the user does not desire to view.
- step 301 other methods may be used to monitor whether the currently received first media stream contains content that the user does not desire to view, and is not described here.
- the playback device may first prompt the user whether to switch. To the second media stream. When the user indicates that the second media stream needs to be switched, the switching operation is performed, otherwise the first media stream is continued to be played.
- step 302 specifically includes:
- the step of playing the second media stream is received upon receiving an acknowledgment indication that the user needs to play the second media stream.
- the playing device in the embodiment of the present invention can simultaneously simultaneously play the second media stream.
- the content of the undesired viewing of the content included in the first media stream is monitored, and the first media stream is replayed after monitoring that the content that the user does not desire to watch is played.

上述实施例中提到, 在当前接收到的第一媒体流中包含用户非期望收看的内容 时, 不播放所述用户非期望收看的内容, 而是播放第二媒体流, 此时, 可以有效屏幕 用户非期望收看的内容。 然而, 在有些情况下, 即使当前接收到的所述第一媒体流中
包含用户非期望收看的内容, 然而, 用户仍然希望继续播放所述第一媒体流, 此时, 如果自动切换至所述第二媒体流, 则违背用户意愿。 因此, 优选的, 在监测出当前接 收到的第一媒体流中包含用户非期望收看的内容时, 所述播放设备可以首先提示用户 是否需要切换至所述第二媒体流, 例如可以在显示屏幕上显示一切换提示信息, 提示 用户是否需要切换。 在用户指示需要切换至所述第二媒体流时, 再执行切换操作, 否 则继续播放所述第一媒体流。

第四种监测方法如下所示:
如果所述播放设备是采用双播放窗口的方式, 同时播放所述第一媒体流和所述第 二媒体流时, 此时, 用户可以自己观看所述第一媒体流对应的播放窗口, 观看用户非 期望收看的内容是否播放完毕, 并可以在观看到用户非期望收看的内容播放完毕后, 通过电视遥控器、鼠标或键盘等,将所述第一媒体流的播放窗口切换成全屏播放方式, 同时关闭所述第二媒体流的播放窗口。
可以理解的是, 所述播放设备需要在切换至所述第二媒体流时, 保存所述第一媒 体流的信息 (例如台位信息、 网络地址信息等), 在所述第一媒体流中包含的用户非
期望收看的内容的播放时间结束时, 根据保存的所述第一媒体流的信息, 切换回所述 第一媒体流。
然而, 在有些情况下, 在切换至所述第二媒体流后, 用户可能不再需要切换回所 述第一媒体流, 因此, 优选的, 在判断出所述第一媒体流中包含的用户非期望收看的 内容的播放时间结束时, 所述播放设备可以提示用户是否需要切换回所述第一媒体 流, 例如可以在显示屏幕上可以显示一切换提示信息, 提示用户是否需要切换。 在用 户指示需要切换回第一媒体流时, 在执行切换操作, 否则继续播放所述第二媒体流。

在切换至所述第二媒体流之前, 所述播放设备可以获取所述用户非期望收看的内 容的播放时间,并启动一计时器,对所述用户非期望收看的内容的播放时间进行计时, 在计时结束时, 判定所述用户非期望收看的内容的播放时间已结束。
第三种监测方法如下所示:
在监测到所述第一媒体流中包含用户非期望收看的内容时, 可以获取所述用户非 期望收看的内容的播放时间, 并对所述用户非期望收看的内容的播放时间进行计时。
同时, 无论用户是否切换至所述第二媒体流, 均将所述计时信息显示在所述播放 设备的显示屏幕上, 使得用户能够根据所述计时信息, 判断所述用户非期望收看的内 容的播放时间是否结束。 另外, 用户可以在已切换至所述第二媒体流, 且所述计时信 息显示的所述用户非期望收看的内容的播放时间结束时, 通过电视遥控器、 鼠标或键 盘等, 切换回所述第一媒体流。
基于上述描述, 上述步驟 401之后还包括:
在所述监测结果表示所述第一媒体流中包含用户非期望收看的内容时, 对所述用 户非期望收看的内容的播放时间进行计时, 并产生一计时信息的步骤; 以及
将所述计时信息提示给用户的步骤, 从而使得用户能够根据所述计时信息判断所 述用户非期望收看的内容的播放时间是否结束。
第四种监测方法如下所示:
如果所述播放设备是采用双播放窗口的方式, 同时播放所述第一媒体流和所述第 二媒体流时, 此时, 用户可以自己观看所述第一媒体流对应的播放窗口, 观看用户非 期望收看的内容是否播放完毕, 并可以在观看到用户非期望收看的内容播放完毕后, 通过电视遥控器、鼠标或键盘等,将所述第一媒体流的播放窗口切换成全屏播放方式, 同时关闭所述第二媒体流的播放窗口。
下述实施例中, 以广告为所述用户非期望收看的内容为例, 对本发明实施例的播 放方法进行说明。
如图 5所示为本发明实施例的播放方法的又一流程示意图, 所述方法包括以下步 骤:
步骤 501 , 监测当前接收到的第一媒体流中是否包含广告, 并产生一监测结果; 步骤 502, 在所述监测结果表示所述第一媒体流中包含广告时,播放第二媒体流, 所述第二媒体流与所述第一媒体流不同。
步骤 503 , 在所述监测结果表示所述第一媒体流中不包含广告时, 继续播放所述 第一媒体流。
所述第二媒体流可以为预先存储于所述播放设备中的本地媒体流, 例如: 本地存 储的视频文件、 音乐文件、 图片和网页等媒体流, 此时, 所述播放设备需要获取所述 本地媒体流的存储路径, 并根据所述存储路径, 播放所述本地媒体流。
或者, 所述第二媒体流还可以为位于互联网上的网络媒体流, 此时, 所述播放设 备需要获取所述网络媒体 ¾的网络地址,并根据所述网络地址,播放所述网络媒体流。
又或者, 所述第二媒体流还可以为预设电视频道的媒体流, 此时, 所述播放设备 需要获取所述预设电视频道的台位信息, 并根据所述台位信息, 播放所述预设电视频 道的媒体流。
需要注意的是, 在切换至预设电视频道后, 可以对当前接收到的所述预设电视频 道的媒体流继续进行监测, 如果监测到当前接收到的所述预设电视频道的媒体流包含 广告, 则可以继续切换至其他预设的电视频道(或者本地媒体流、 网络媒体流等), 以此类推, 直至找到不包含广告的电视频道。
在监测到当前接收到的第一媒体流中包含广告时, 所述播放设备可以直接不接收 所述第一媒体流; 或者, 也可以继续接收所述第一媒体流, 只是不进行播放; 又或者, 采用双播放窗口的方式播放所述第一媒体流和所述第二媒体流, 即, 在当前显示屏幕 上显示两个播放窗口, 分别播放所述第一媒体流和所述第二媒体流, 例如, 以较大的 播放窗口播放所述第二媒体流, 以方便用户观看, 以较小的播放窗口播放所述第一媒 体流。
上述步骤 501中, 可以通过多种方式判断当前接收到的第一媒体流中是否包含广 告, 下面将详细进行描述。
第一种监测方式如下所示:
殳在一个媒体流中, 可以通过不同类型的标签来区分不同的媒体内容, 例如, 在媒体流的首字节中添加 1 , 表示该媒体流为电影, 在媒体流的首字节中添加 0, 表 示该媒体流为广告。
可以将广告的标签预先存储于所述播放设备中, 并在所述播放设备中安装一标签 监测程序, 检测当前接收到的媒体内容的标签, 从而来判定是否接收到广告。
第二种监测方式如下所示:
假设电视频道当天需要播放的电视节目和电视节目的播放时间均预先存储于一 播放时间表中。 在用户通过播放设备观看该电视频道时, 所述播放设备可以从相应的 服务器上, 下载所述播放时间表, 并根据上述播放时间表, 获取广告妁播放时间, 同 时设置一播放时间监测程序, 监测当前是否到达广告的播放时间, 在监测到当前已到 达广告的播放时间时, 判定当前接收到的第一媒体流中包含广告。
第三种监测方式如下所示:
所述播放设备可以将当'前接收到的视频帧与前一个或前多个接收到的视频帧进 行比较, 计算两者的相关性, 来判断当前接收到的视频帧是否为广告的视频帧, 从而 来判定当前接收到的第一媒体流中是否包含广告。
第四种监测方式如下所示:
所述播放设备可以预先设置一视频帧数据库, 存储广告的第一视频帧, 并设置一 视频帧匹配程序, 将当前接收到的视频帧与所述第一视频帧进行匹配, 在当前接收到 的视频帧与所述第一视频帧相同时, 判定当前接收到的第一媒体流中包含广告。
除了上述几种监测方法外, 当然, 上述步骤 501中还可以采用其他方式来监测当 前接收到的第一媒体流是否包含广告, 在此则不再——说明。
上述实施例中提到,在当前接收到的第一媒体流中包含广告时,不播放所述广告, 而是播放第二媒体流, 此时, 可以有效屏幕广告。 然而, 在有些情况下, 即使所述第 一媒体流中包含广告, 然而, 用户仍然希望继续观看所述第一媒体流, 此时, 如果自 动切换至所述第二媒体流, 则违背用户意愿。 因此, 优选的, 在监测出当前接收到的 第一媒体流中包含广告时, 所述播放设备可以首先提示用户是否需要切换至所述第二 媒体流。 在用户指示需要切换至所述第二媒体流时, 再执行切换操作, 否则继续播放 所述第一媒体流。
因此, 上述步骤 502具体包括:
在所述监测结果表示所述第一媒体流中包含广告时, 提示用户是否需要播放所述 第二媒体流的步骤; 以及
在接收到用户需要播放所述第二媒体流的确认指示时, 播放所述第二媒体流的步 骤。
在广告播放完毕后, 通常情况下用户还是希望切换至原来收看的第一视频流, 因 此, 本发明实施例中的播放设备在播放所述第二媒体流时, 还可以同时监测所述第一 媒体流中包含的广告是否播放完毕, 在监测到所述广告播放完毕后, 重新播放所述第
一媒体流。
如图 6所示为本发明实施例的播放方法的再一流程示意图, 所述方法包括以下步 骤:
步骤 601, 监测当前接收到的第一媒体流中是否包含广告, 并产生一监测结果; 在所述监测结果表示所述第一媒体流中包含广告时, 执行步骤 602, 否则, 执行步驟 606;
步驟 602, 判断用户是否需要播放第二媒体流, 所述第二媒体流与所述第一媒体 流不同。 在接收到用户需要播放所述第二媒体流的确认指示时, 执行步骤 603 , 否贝' J , 执行步骤 606;
步骤 603 , 播放所述第二媒体流;
步骤 604, 继续播放所述第一媒体流。
步骤 605, 监测所述广告的播放时间是否结束, 并产生一监测结果; 在所述监测 结果表示所述广告的播放时间结束时, 执行步骤 606, 否则执行步骤 608.
步骤 606 , 判断用户是否需要播放所述第一媒体流, 在接收到用户需要播放所述 第一媒体流的确认指示时, 执行步骤 607, 否则, 执行步骤 608;
步骤 607, 播放所述第一媒体流。
步骤 608, 继续播放所述第二媒体流。
上述步骤 605中, 可以采用多种方式判断所述广告的播放时间是否结束, 下面将 进行详细说明。
第一种监测方式如下所示:
' 如果所述播放设备在切换至所述第二媒体流的同时, 仍继续接收所述第一媒体 流, 此时, 可以根据接收到的第一媒体流中的媒体内容的标签, 监测所述第一媒体流 中包含的广告是否接收完毕, 在监测到所述广告接收完毕后, 则可以判定所述广告的 播放时间已结束。
第二种监测方式如下所示:
在切换至所述第二媒体流之前, 所述播放设备可以获取所述广告的播放时间, 并 启动一计时器, 对所述广告的播放时间进行计时, 在计时结束时, 判定所述广告的播 放时间已结束。
第三种监测方法如下所示:
在监测到所述第一媒体流中包含广告时, 可以获取所述广告的播放时间, 并对所 述广告的播放时间进行计时。
同时, 无论用户是否切换至所述第二媒体流, 均将所述计时信息显示在所述播放 设备的显示屏幕上, 使得用户能够根据所述计时信息, 判断所述广告的播放时间是否 结束。 另外, 用户可以在已切换至所述第二媒体流, 且所述计时信息显示的所述广告 的播放时间结束时, 通过电视遥控器、 鼠标或键盘等, ·切换回所述第一媒体流。
基于上述描述, 上述步骤 601之后还包括:
在所述监测结果表示所述第一媒体流中包含广告时, 对所述广告的播放时间进行 计时, 并产生一计时信息的步骤; 以及
将所述计时信息提示给用户的步骤, 从而使得用户能够根据所述计时信息判断所 述广告的播放时间是否结束。
第四种监测方法如下所示:
如果所述播放设备是采用双播放窗口的方式, 同时播放所述第一媒体流和所述第 二媒体流时, 此时, 用户可以自己观看所述第一媒体流对应的播放窗口, 观看广告是 否播放完毕, 并可以在观看到广告播放完毕后, 通过电视遥控器、 鼠标或键盘等, 将 所述第一媒体流的播放窗口切换成全屏播放方式, 同时关闭所述第二媒体流的播放窗 口。
通过上述实施例提供的播放方法, 可以在当前接收到的第一媒体流中包含广告 时, 不播放广告, 而是播放第二媒体流, 从而使得用户可以不被广告打扰, 另外, 还 可以在广告的播放时间结束后,重新切换回原来收看的第一媒体流,提高了用户体验。
如图 7所示为本发明实施例的播放设备的又一结构示意图, 所述播放设备可以为 一电视机、 与电视显示屏幕连接的机顶盒、 计算机或手机等设备。 假设所述播放设备 当前播放的媒体流为第一媒体流, 所述第一媒体流包含的内容可以为两类内容, 一类 为用户期望收看的内容, 一类为用户非期望收看的内容。 所述用户期望收看的内容和 用户非期望收看的内容可以由用户预设设置, 并存储于所述播放设备中, 例如, 用户 设置的期望收看的内容为电视剧、 电影等, 非期望收看的内容为广告、 新闻等。
现有技术中, 在当前需要播放的第一媒体流中包含用户非期望收看的内容时, 用 户可以切换到当前内容为用户期望收看的内容的第二媒体流进行播放, 然而, 在切换 到第二媒体流时, 却无法在所述第一媒体流中包含用户非期望收看的内容播放结束 时, 及时切换回所述第一媒体流。
为了达到及时切换回所述第一媒体流的目的, 本发明实施例中的播放设备还包 括:

另外, 用户可以在已切换至所述第二媒体流, 且所述计时信息显示的所述广告的 播放时间结束时, 通过电视遥控器、 鼠标或键盘等, 切换回所述第一媒体流。
下述实施例中, 以广告为所述用户非期望收看的内容为例, 对上述播放设备进行 说明。
所述播放设备可以为一电视机、 与电视显示屏幕连接的机顶盒、 计算机或手机等 设备。 假设所述播放设备当前播放的媒体流为第一媒体流, 现有技术中, 在当前需要 播放的第一媒体流中包含广告时, 用户可以会切换到第二媒体流, 然而, 在切换到第 二媒体流时, 却无法在所述第一媒体流中包含广告播放结束时, 及时切换回所述第一 媒体流。
为了达到及时切换回所述第一媒体流的目的, 本发明实施例中的播放设备还包 括:
监测模块, 用于监测当前接收到的第一媒体流中是否包含广告, 并产生一监测结 果; 具体的, 所述监测模块可以采用与上述实施例中的监测模块 102相同的方法, 判
定当前接收到的第一媒体流中是否包含广告, 在此不再重复描述。
