图3是根据本发明优选实施例的交互流程示意图，如图3所示，本优选实施例所用到的技术方案包括：一回播数据采集模块，该模块采集“一键联想”按下前30秒节目的所有数据信息；一语音识别模块，设置为识别30秒内语音关键词，进行关键词匹配联想相关节目；一声音辨识模块，设置为辨识30秒内声音特质识别相似声音联想相关节目；一人像识别模块，设置为识别30秒内出现特写(篇幅大于画面的1/4)的演员；一节目单分析模块，该模块通过对节目单信息提取关键词进行搜索；一数据分析模块，该模块将之前四个模块的反馈结果进行数据交叉分析，综合得出最优结果。
图4是根据本发明优选实施例的在不同设备上的搜索流程示意图，如图4所示，下面是不同的设备上的搜索流程。
一、使用无屏遥控设备对播放终端节目内容的搜索方法
1、在无屏遥控设备发送搜索指令；
2、播放终端接收到遥控设备发出的搜索信号，系统自动开启采集模块对过去30秒的节目内容进行回播数据采集；
3、采集完成后，解码模块将收集到的节目内容分解为视频流、音频流和节目文本信息；
4、视频流分析过程
(1)视频分析模块通过色调、对比度将视频流分解为一个或多个场景后，后台使用图像识别模块，同时对几个场景中出现的演员进行多任务并行分析；
(2)系统识别出某个人物后，运动跟踪模块将对识别出的人物进行跟踪打点，若此跟踪点在场景内未消失，图像识别模块不再对当前人物进行图像匹配；
5音频流分析过程
(1)音频分析模块通过音色区分出不同特质的声音，获取不同声音片段；
(2)音频分析模块通过音调捕获音乐旋律；
(3)音频分析模块通过收集的音频信息，获取频繁出现的音频关键词；
6、节目单文本分析过程
节目单分析模块将获取此节目的名称、演员表、关键词和评价标签热词；
7、当数据分析完成后，数据匹配模块将对所获取的人物关键词、声音关键词、音乐关键词、音频关键词及节目内容关键词与数据库信息进行综合匹配分析提取交集信息，输出结果；
8数据匹配完成后，显示模块会将后台数据结果反馈至播放终端界面上。
二、使用有屏遥控设备对播放终端节目内容的搜索方法
1、在有屏设备(与电视在统一局域网内)上发送搜索指令；
2、播放终端接收到有屏遥控设备发出的搜索信号，系统自动开启采集模块对过去30秒的节目内容进行回播数据采集；
3、数据推送模块将30秒内数据推送至有屏遥控设备，有屏设备系统判断接收完成后将发出通知，让用户自行选择回播30秒节目内容或直接查看搜索结果；
4、若系统接收到“回播”命令，有屏遥控设备将进入视频播放模式；
(1)通过视频分析模块得到几个主要场景，在视频的播放时间轴上显示提醒标记，可用于快速定位；
(2)当系统接收到触控操作时，后台自动开启手势识别模块，接收到用户的画圈手势或点击操作时，播放器将暂停视频播放，视频分析模块将对此区域内的人像进行图像识别；
(3)开启数据分析模块，对所获取的人物关键词与数据库信息进行匹配分析，输出结果；
5、若系统接收到“查看搜索结果”命令，有屏遥控设备将接收播放终端分析出的数据结果；
6、数据匹配完成后，显示模块会将后台数据结果反馈至有屏设备界面上。
图5是根据本发明优选实施例的电视端结果展现交互示意图，如图5所示，
应用场景一：通过遥控器对电视发送搜索指令，搜索结果在电视端呈现
在观看节目时，通过长按遥控器上的搜索键发送“一键联想”指令；
后台数据库开启语音识别、声音辨识、人像识别、节目单分析等模块，对采集的数据得出联想结果并进行分析，之后反馈至电视界面呈现。
图6是根据本发明优选实施例的移动终端和PC搜索结果展示示意图，如图6所示，
应用场景二：通过遥控器对电视发送搜索指令，搜索结果在移动终端呈现
在观看节目时，通过遥控器或与电视在同一局域网内且关联的移动终端设备发送“一键联想”指令；
后台数据库将采集分析的30秒内数据推送至所关联的移动终端，此时用户可在移动终端选择回看30秒节目内容或直接浏览搜索结果；
若用户选择回看30秒节目，可通过画圈或点击确定人像搜索区域，系统对此区域内的人像进行人脸识别搜索，将人脸识别关键词与后台数据库中的节目信息等进行智能搜索匹配，在移动终端呈现最优搜索结果；
若用户在移动终端上无任何操作，则后台数据库开启语音识别、声音辨识、人像识别、节目单分析等模块，对采集的数据得出联想结果并进行分析，之后在移动端呈现最优搜索结果。
应用场景三：通过遥控器对电视发送搜索指令，搜索结果在PC端呈现
在观看节目时，通过遥控器发送“一键联想”指令；
若此时有在同一局域网内且与电视关联的PC终端设备开启，后台数据库将采集分析的30秒内数据推送至所关联的PC终端，此时用户可在移动终端选择回看30秒节目内容或直接浏览搜索结果；
若用户选择回看30秒节目，可通过鼠标拖动选择搜索区域，系统对此区域内的人像进行人脸识别搜索，将人脸识别关键词与后台数据库中的节目信息等进行智能搜索匹配，呈现最优搜索结果。
