具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
信息推送系统包括至少一个主显示设备和至少一个辅显示设备，用户在通过主显示设备观看视频服务系统提供的视频时，若用户想与当前观看的视频进行互动，如发微博、观看相关广告等，可以通过辅显示设备来实现。本发明实施例提供一种信息推送方法，用于信息推送设备，所述信息推送设备可以是数字电视机顶盒、智能电视和带视频播放功能的游戏终等，如图1所示，包括：
步骤101、建立主显示设备与辅显示设备的通信连接。
主显示设备是一种具有联网能力，能够接收和解码视频数据流的电子设备，在本实施例中可以称为第N屏设备，该主显示设备包括：智能电视、智能手机、平板电脑等。辅显示设备通常作为主显示设备的一种补充设备，能够与该主显示设备联动和共享内容，在本实施例中可称为第N屏设备，其中N大于或等于二。该辅显示设备也是一种具有联网能力，能够接收和解码视频数据流的电子设备，比如：智能电视、智能手机、平板电脑等。
步骤102、获取主显示设备的设备标识。
步骤103、在该主显示设备发生第一播放事件时，从视频服务系统获取与该第一播放事件对应的播放信息。
播放信息包括直播视频播放时间表或点播视频播放时间表。
步骤104、根据第一播放事件、主显示设备的设备标识和播放信息获取播放事件信息。
具体的，信息推送设备首先可以根据第一播放事件生成事件标识以便于标识所述第一播放事件类型；再可以根据播放信息获取第一播放事件的视频内容标识，该播放信息包括直播视频播放时间表或点播视频播放时间表；最后，生成该播放事件信息，该播放事件信息包括该事件标识、该主显示设备标识和该视频内容标识。
步骤105、根据预设规则和播放事件信息，确定待推送信息。
推送设备预设规则，该预设规则是根据直播视频或者点播视频的播放事件信息确定向辅显示设备发送的信息，该信息可以是直播视频或者点播视频，也可以是直播视频和点播视频相关的内容，例如广告、节目互动等。
步骤106、向辅显示设备推送待推送信息。
这样一来，信息推送设备根据从视频服务系统获取的播放信息，获取第一播放事件的视频内容标识，提高了获取播放视频内容的正确率，从而提高了推送信息的正确率。
进一步的，信息推送设备根据播放信息获取第一播放事件的视频内容标识，可以分为两种应用场景，第一种应用场景，视频服务系统向主显示设备提供直播视频；第二种应用场景，视频服务系统向主显示设备提供视频点播。
当视频服务系统向主显示设备提供直播视频时，第一播放事件为直播视频开始、直播视频播放和直播视频结束中的任意一种，根据播放信息获取第一播放事件的视频内容标识包括：信息推送设备可以获取第一播放事件的实时发生时间，该实时发生时间是指当前的时钟时间；获取播放信息中的直播视频播放时间表，该直播视频播放时间表记录了该视频服务系统中的直播视频的视频播放时间段和对应的视频内容标识；根据第一播放事件的实时发生时间，查询直播视频播放时间表，获取实时发生时间所在的视频播放时间段对应的视频内容标识作为第一播放事件的视频内容标识。
当视频服务系统向主显示设备提供点播视频时，第一播放事件为点播视频开始、点播视频播放、点播视频结束、点播视频快退和点播视频快进中的任意一种，根据播放信息获取第一播放事件的视频内容标识包括：信息推送设备可以获取第一播放事件的实时发生时间，该实时发生时间是指该点播视频当前帧对应的视频时刻；获取播放信息中的点播视 频播放时间表，该点播视频播放时间表记录了该点播视频的各个小节的播放时间段和对应的视频内容标识；根据该第一播放事件的实时发生时间，查询该点播视频播放时间表，获取实时发生时间所在的小节的播放时间段所对应的视频内容标识作为第一播放事件的视频内容标识。
实际应用中，所述信息可以为多种形式，在本实施例中，假设所述信息为广告，所述主显示设备为智能电视，所述辅显示设备为手机，本发明实施例提供一种信息推送方法，如图2所示，包括：
步骤201、智能电视向信息推送设备发送注册信息。
智能电视的注册信息包括：智能电视的设备标识，智能电视对应的用户标识。智能电视的设备标识可以为该电视的出厂编号，内部芯片编号，主板编号，或者识别码等。本实施例假设该智能电视的设备标识为D0003。
信息推送设备可以在接收到注册信息后，将注册信息在数据库中保存，通常可以将该注册信息填入设备管理表的主显示设备表项中，设备管理表记录有已注册的所有主显示设备与辅显示设备的设备标识。
步骤202、手机向信息推送设备发送注册信息。
手机的注册信息可以包括：手机的设备标识，手机对应的用户标识和接收端口类型，该接收端口类型用于指示手机的接收端口能够承载的信息类型，该信息类型可以为短信，TCP(Transmission Control Protocol，传输控制协议)/IP(Internet Protocol，网际协议)消息，基于TCP/IP或者HTTP(Hypertext Transfer Protocol，超文本传输协议)的XMPP(Extensible Messaging and Presence Protocol，可扩展通讯和表示协议)消息。基于TCP/IP或者HTTP的XMPP消息可以包括iOS(苹果操作系统)和Android(安卓)的系统通知，通过IP网络承载的视频，通过XMPP推送的文本和图片等。
手机的设备标识可以为全球通用识别码、IMEI(International Mobile Equipment Identity，国际移动设备身份码)，或内置的数字证书编号等。本实施例假设该手机的设备标识为D0004。
信息推送设备在接收到注册信息后，将注册信息在数据库中保存，通常可以将该注册信息填入设备管理表的辅显示设备表项中，设备管理 表记录有已注册的所有主显示设备与辅显示设备的设备标识。
步骤203、信息推送设备建立智能电视与手机的通信连接。
本实施例中，建立智能电视与手机的通信连接可以分为两种应用场景，第一种应用场景是智能电视先于手机进行注册，第二种应用场景是手机先于智能电视进行注册。
当智能电视先于手机进行注册时，信息推送设备可以获取手机的设备标识，手机是以辅显示设备进行注册的，从设备管理表中查询出已注册的包括该智能电视在内的所有主显示设备的设备标识，将所有主显示设备和手机建立通信连接，这样也就建立智能电视与手机的通信连接；
当手机先于智能电视进行注册时，信息推送设备可以获取智能电视的设备标识，智能电视是以主显示设备进行注册的，从设备管理表中查询出已注册的包括该手机在内的所有辅显示设备的设备标识，将所有辅显示设备和智能电视建立通信连接，这样也就建立智能电视与手机的通信连接。
值得说明的是，手机这类设备既可以做主显示设备也可以做辅显示设备，所以手机这类设备可以向自身发送广告。
步骤204、信息推送设备获取智能电视的设备标识。
智能电视的标识可以从智能电视获取，也可以从信息推送设备中保存的智能电视注册信息中获取，本实施例以从信息推送设备中保存的智能电视注册信息中获取为例。
步骤205、信息推送设备获取第一播放事件。
值得说明的是，视频系统为智能电视提供视频流。
特别说明的是，获取第一播放事件的方法有很多种，例如，视频服务系统获取方法、信息推送设备获取方法、主显示设备获取方法等等。本实施例以信息推送设备获取方法为例。
示例的，当采用视频服务系统获取方法来获取第一播放事件，在第一播放事件发生时，智能电视判断当前的视频流中是否存在与第一事件对应的视频流，若存在，判断发生了第一播放事件，然后向视频服务系统发送与第一播放事件相对应的事件指示，视频服务系统接收到该事件指示后，确定发生第一播放事件，并通知信息推送设备。特别的，视频服务系统可以通过调用信息推送设备的API(Application Programming  Interface，应用程序编程接口)来通知信息推送设备；
示例的，当采用信息推送设备获取方法来获取第一播放事件，信息推送设备实时监控视频服务系统输出的视频流控制报文，当输出的视频流控制报文的特征与控制报文库中的第一播放事件的特定控制报文特征相同确定输出的视频流控制报文对应的第一播放事件，需要说明的是，所述控制报文库存储有与播放事件相对应的控制报文；
示例的，当视频服务系统与主显示设备的连接断开时，如当前播放视频已经下载在主显示设备本地，可以采用主显示设备获取方法获取第一播放事件，即智能电视播放视频时，判断当前的视频流中是否存在与第一事件对应的视频流，若存在，智能电视直接向信息推送设备发送上报消息，该上报消息包括第一播放事件。
步骤206、信息推送设备从视频服务系统获取播放信息。
该播放信息包括直播视频播放时间表或点播视频播放时间表。
直播视频播放时间表记录了视频服务系统中的直播视频的视频播放时间段和对应的视频内容标识；点播视频播放时间表记录了点播视频的各个小节的播放时间段和对应的视频内容标识。
步骤207、信息推送设备根据第一播放事件、主显示设备的设备标识和播放信息获取播放事件信息。
推送设备根据第一播放事件生成事件标识；根据播放信息获取第一播放事件的视频内容标识；生成播放事件信息，该播放事件信息包括事件标识、智能电视的设备标识和视频内容标识。
值得说明的是，根据播放信息获取第一播放事件的视频内容标识，可以分为两种应用场景，第一种应用场景，视频服务系统向智能电视提供直播视频，第二种应用场景，视频服务系统向智能电视提供视频点播。
具体的，当视频服务系统向智能电视提供直播视频时，第一播放事件为直播视频开始、直播视频播放和直播视频结束中的任意一种，根据播放信息获取第一播放事件的视频内容标识包括：信息推送设备可以获取第一播放事件的实时发生时间，该实时发生时间是指当前的时钟时间；获取播放信息中的直播视频播放时间表，直播视频播放时间表记录了视频服务系统中的直播视频的视频播放时间段和对应的视频内容标识；根据第一播放事件的实时发生时间，查询直播视频播放时间表，获取实时 发生时间所在的视频播放时间段对应的视频内容标识作为第一播放事件的视频内容标识。示例的，直播视频的实时发生时间是6:30，查询直播视频播放时间表如表1，对应的播放事件段6:00-7:00，获取对应的视频内容标识为10，生成播放事件信息。
表1
视频播放时间段 视频内容标识
6:00-7:00 10
7:00-7:30 11
7:30-8:00 12
具体的，当视频服务系统向智能电视提供点播视频时，第一播放事件为点播视频开始、点播视频播放、点播视频结束、点播视频快退和点播视频快进中的任意一种，根据播放信息获取第一播放事件的视频内容标识包括：信息推送设备可以获取第一播放事件的实时发生时间；获取播放信息中点播视频播放时间表，点播视频播放时间表记录了点播视频的各个小节的播放时间段和对应的视频内容标识；根据第一播放事件的实时发生时间，查询点播视频播放时间表，获取实时发生时间所在的小节的播放时间段所对应的视频内容标识作为第一播放事件的视频内容标识。示例的，假设点播视频的实时发生时间是0:12，查询点播视频播放时间表如表2，对应的播放事件段0:05-0:15，获取对应的视频内容标识为10，生成播放事件信息。
表2
Figure PCTCN2014087061-appb-000001
步骤208、根据预设规则和播放事件信息，确定待推送信息。
推送设备可以根据视频内容标识确定当前视频内容，推送设备可以根据事件标识和当前视频内容按照预设规则确定待推送信息，该预设规则可以包括根据事件信息中的视频内容标识选择与该视频内容对应的内容相关的带推送信息，再根据主显示设备辅显示设备注册信息和事件 标识确定手机能后接收待推送信息的类型。假设事件标识为直播视频暂停，视频内容标识指示当前播放的视频为足球比赛；视频内容标识选择与该视频内容对应的广告，再根据智能电视的标识查找到手机的注册信息；信息推送设备可以在智能电视直播视频暂停时向手机发送足球类彩信广告。
需要说明的是，信息推送设备也可以建立智能电视和手机通信连接时，在数据库中获得对应的用户标识所关联的用户情况，在广告推送前，根据用户情况再进行进一步筛选，例如，事件标识为暂停视频播放，若获取得到用户的性别为女性，年龄为25岁，用户所处地区为北京，视频内容标识指示当前播放的视频为电视剧，则根据预设规则可以在智能电视暂停视频播放时，向手机发送电视剧中人物穿着的服饰或化妆品的广告，若手机的接收端口能够承载的信息类型为通过XMPP推送的文本和图片，则广告类型为通过XMPP推送的文本和图片。这样可以进一步根据用户的具体情况发送对应的广告，提高广告的有效性。
值得说明的是，由于手机的注册信息中包括接收端口类型，接收端口类型用于指示手机的接收端口能够承载的信息类型，因此信息推送设备可以根据接收端口类型在数据库中选择相应信息类型的信息作为待推送信息；信息类型可以为短信，TCP/IP消息，基于TCP/IP或者HTTP的XMPP消息。基于TCP/IP或者HTTP的XMPP消息可以包括iOS和Android的系统通知，通过IP网络承载的视频，通过XMPP推送的文本和图片等。
这样一来，由于在手机的注册信息中包括接收端口类型，使得广告发送时，可以区分接口类型，实现广告下发格式和方法的多样化，提高广告命中的准确性。
步骤209、信息推送设备向手机推送待推送信息。
需要说明的是，步骤206至步骤209可以通过信息推送设备的API执行的。
本发明实施例提供的信息推送方法，由于在信息推送系统中加入信息推送设备，在主显示设备发生第一播放事件时，信息推送设备根据从视频服务系统获取播放信息，获取视频内容标识，无需分析声音信息来确定播放事件，提高了获取播放视频内容的正确率，从而提高了推送信息的正确率，用户也无需靠近电视屏幕进行声音采集，提高了用户体验。 同时，由于在辅显示设备的注册信息中包括接收端口类型，使得信息推送时，可以区分接口类型，实现信息下发格式和方法的多样化，提高信息命中的准确性。
