图3为本发明智能电视视频分享方法第二实施例的流程示意图。
本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种智能电视视频分享方法，在本发明智能电视视频分享方法的第一实施例中，参照图1和图2，该智能电视视频分享方法包括：
步骤S10，获取与智能电视连接的服务器已上传视频文件的文件名列表，其中文件名列表包括已播视频文件名和未播视频文件名；
智能电视100通过HFC(Hybrid Fiber－Coaxial, 混合光纤同轴电缆网)网络400与服务器200连接，可选地，服务器200与HFC网络400之间还连接有复用器300。服务器200依次将未播放的封装节目流传入到复用器300，然后复用器300将该未播放的封装节目流传入HFC网络400，并基于HFC网络400下发到各个预设频点(预设频点都是固定频点)以供智能电视100搜索预设频点观看节目，然后对该下发过的封装节目流设置已播放属性，即该封装节目流的文件名已经成为已播视频文件名，对应的，保存在服务器200但未下发预设频点的封装节目流的文件名即为未播视频文件名，已播视频文件名和未播视频文件名共同构成文件名列表。封装节目流可以为TS流（Transport Stream，传输流）、PS流、ES流
智能电视100获取服务器200上已上传文件的文件名列表，解析获取文件名列表中的已播视频文件名和未播视频文件名，以与待分享视频的文件名进行比较。
步骤S20，比较智能电视待分享视频的文件名与文件名列表，获取待分享视频文件名与文件名列表的相似度，其中将待分享视频文件名与文件名列表的相似度作为比较相似度；
用户可通过对智能电视100输入操作指令以选择并确定待分享视频，智能电视100获取待分享视频的文件名，将待分享文件名与文件名列表中的已播视频文件名和未播视频文件名进行比较，综合得出待分享视频文件名和文件名列表的相似度，即综合得出比较相似度，该比较相似度反映出待分享视频文件名与文件名列表中各视频文件名的相似程度。
步骤S30，若比较相似度小于相似度阈值，则将待分享视频封装成封装节目流；
步骤S40，将该封装节目流发送至服务器以供服务器将接收的封装节目流通过HFC网络下发至处于各个预设频点。
相似度阈值可在智能电视出厂时设置，也可以是用户自行设置的，例如相似度阈值为80%。当比较相似度大于相似度阈值时，表明此时的待分享视频的文件名与服务器上已上传视频的文件名基本相同，也即待分享视频与服务器上已上传视频很可能是相同的，所以智能电视对此时的待分享视频不作分享、不发给服务器；当比较相似度小于相似度阈值时，表明此时的待分享视频的文件名与服务器上已上传视频的文件名不相同，也即待分享视频与服务器上已上传视频很可能是不一样的，所以为了丰富服务器上视频的多样性，智能电视将待分享视频封装成封装节目流，然后将封装的封装节目流发送至服务器以供服务器将接收的封装节目流下发至处于各个预设频点，从而其它智能电视搜索预设频点观看视频节目。
在本实施例中，通过获取与服务器已上传视频文件的文件名列表，比较智能电视待分享视频的文件名与所述文件名列表，获取比较相似度；若比较相似度小于相似度阈值，则将待分享视频封装成封装节目流，并将该封装节目流发送至服务器以供服务器将接收的封装节目流下发至处于各个预设频点，从而实现用户后台分享自己的影片（即待分享视频），通过智能电视所连接的同轴电缆传输分享的视频到预设频点以实现直播频道观看，从而无需互联网也可以观看其他人分享的视频，进而解决了智能电视因带宽问题出现视频卡顿、影响观影效果的问题。从某种角度说，利用由智能电视、服务器和HFC网络替代了互联网，通过智能电视间的视频分享替代了互联网上的视频分享。
进一步地，在本发明智能电视视频分享方法第一实施例的基础上，提出智能电视视频分享方法第二实施例，参照图3，在第二实施例中，智能电视视频分享方法还包括：
步骤S50，根据预设校验算法对待分享视频进行校验以获取第一校验码，并将该第一校验码封装到封装节目流中，以供服务器基于预设校验算法校验封装节目流中待分享视频得到第二校验码，且比对第二校验码和第一校验码，服务器仅在第一校验码和第二校验码匹配时保存接收到的封装节目流作为未播放封装节目流。
智能电视在确定待分享视频后，根据预设校验算法对待分享视频进行校验，获取第一验证码，并将第一校验码封装到封装节目流中以一并发送至服务器；服务器在接收到智能电视发送的封装节目流后，解析出待分享视频和第一验证码，然后基于预设校验算法对解析出的待分享视频进行校验，获得第二验证码，然后服务器比较第一校验码和第二校验码，当第一校验码和第二校验码相同或匹配时，即待分享视频在上传过程中无数据损失，服务器保留当前接收的待分享视频；当第一校验码和第二校验码不相同或不匹配时，表明待分享视频在上传过程中很可能出现了数据损失，服务器丢弃当前待分享视频；从而有利于服务器对上传的待分享视频是否出现数据损失进行校验，避免服务器保留和下发已经出现数据损失的待分享视频，提高了待分享视频分享的有效性。
进一步地，在本发明智能电视视频分享方法第一实施例的基础上，提出智能电视视频分享方法第三实施例，在第三实施例中，步骤S20包括：
步骤S21，根据预设分词算法，将待分享视频的文件名分词为多个单词以形成第一词组、将文件名列表中多个文件名分词为多个单词以形成对应数量的第二词组；
步骤S22，获取第一词组中的单词个数并统计第二词组的词组个数，其中将第一词组单词个数作为第一单词数，将第二词组的词组个数作为第二词组数；
步骤S23，将第一词组中单词逐个与各个第二词组中单词进行比较，获取第一词组与各个第二词组具有相同单词的同词个数；
步骤S24，根据第一单词数、第二词组数和所有对应的同词个数，计算得出比较相似度。
本发明可适用于英文文件名、中文文件名和中英文混合文件名的分词，由于在英文的行文中，单词之间是以空格作为自然分界符的，故而英文文件名的分词较为简单，不做详细解释；中英文混合文件名分词时主要是先将中文和英文区分，并分别对中文和英文进行分词；而中文只有字、句和段能通过明显的分界符来简单划界，唯独词没有一个形式上的分界符，所以中文的分词较为复杂，以下主要解释中文分词算法，中文分词算法将一个汉字序列切分成一个一个单独的词，也就是将连续的汉字序列按照一定的规范重新组合成词序列的过程。当然，本发明的分词算法不限定于中文分词算法。
中文分词算法一般包括字符匹配法、理解法等，字符匹配法是按照一定的策略将待分析的汉字串（相当于待分享视频文件名）与一个“充分大的”机器词典（相当于文件名列表中文件名）中的词条进行配，若在词典中找到某个字符串，则匹配成功；理解法是通过让计算机模拟人对句子的理解，达到识别词的效果，其基本思想就是在分词的同时进行句法、语义分析，利用句法信息和语义信息来处理歧义现象；其中匹配法应用较为广泛，本实施例应用匹配法，以下以匹配法解释说明本发明实施例。
基于设定的汉语规范将待分享视频的文件名分词为多个单词，具体地可以是：优先在待分享视频的文件名中识别和切分出一些带有明显特征的词（例如“是”、“有”等动词、数字与汉字交界的词、英文与汉字交界的词等），以这些词作为断点，可将原文件名分为较小的汉字串，然后有序拆分汉字串去匹配预设的汉字词库，文件名中与汉字词库相同的拆分后汉字串作为一个单词。
例如，待分享视频的文件名为“2008年北京奥运年鸟巢体育馆开幕式现场直播”，则通过分词算法可分词为“2008”，“年”，“北京”，“奥运会”，“鸟巢”，“体育馆”，“开幕式”，“现场”，“直播”九个单词，这九个单词共同组成第一词组，即第一词组是这九个单词的集合，将第一词组中的单词个数作为第一单词数，即第一单词数为9。
文件名列表中包括三个已分享视频的文件名，分别是文件名一、文件名二和文件名三，文件名一是“2008年北京奥运会”，对应的第二词组A为{“2008”，“年”，“北京”，“奥运会”}；文件名二是“北京奥运会比赛现场”，对应的第二词组B为｛“北京”，“奥运会”，“比赛”，“现场”｝；文件名三是“2008奥运会开幕式”，对应的第二词组C为｛“2008”，“奥运会”，“开幕式”｝，进而得出第二词组的个数（即第二词组数）为3。
然后将第一词组中的单词逐个与第二词组A中的单词进行比较，相同的单词有“2008”、“年”、“北京”和“奥运会”四个相同的单词，所以同词个数A为4；同理第一词组与第二词组B的同词个数B为3，第一词组与第二词组C的同词个数为3。然后根据第一单词数（值为9）和同词个数A（值为4），求出第一词组与第二词组A的初级相似度A，根据第一单词数（值为9）和同词个数B（值为3），求出第一词组与第二词组B的初级相似度B，根据第一单词数（值为9）和同词个数C（值为3），求出第一词组与第二词组C的初级相似度C；如初级相似度A为 = ，初级相似度B为 = ，初级相似度C为 = 。
最后根据初级相似度A、初级相似度B、初级相似度C和第二词组数，计算三个初级相似度的平均值，该平均值即为待分享视频文件名与文件列表的比较相似度，如比较相似度=（ + + ）/3=1/48。
在本实施例中，根据待分享视频的第一单词数、文件名列表中的第二词组数和所有对应的同词个数，计算得出比较相似度提供了一种简单、可行、准确的比较相似度计算算法， 进一步提升了判断待分享视频是否上传服务器的准确性。
进一步地，在本发明智能电视视频分享方法第一实施例的基础上，提出智能电视视频分享方法第四实施例，在第四实施例中，步骤S30包括：
步骤S31，若比较相似度小于相似度阈值，获取当前时间、待分享视频的视频时长和视频文件大小；
步骤S32，根据比较相似度、当前时间、视频时长和视频文件大小，获取待分享视频的播放权重值；
步骤S33，将播放权重值和待分享视频封装成封装节目流以供服务器接收到封装节目流后依据播放权重对各未播放封装节目流进行排序并依据排序顺序下发。
当比较相似度小于相似度阈值时，表明待分享视频在服务器上存在的可能性较小，进而获取当前时间、待分享视频的视频时长和视频文件大小，然后根据比较相似度、当前时间、视频时长和视频文件大小，获取待分享视频的播放权重值，其中比较相似度越高，表明待分享视频与服务器上其它用户上传的视频相关度越高，即表明该待分享视频越流行，故比较相似度与播放权重成正比；当前时间距离预设历史时间越远，表明待分享视频越新颖，故当前时间越靠后播放权重越大；视频时长越长，表明待分享视频的完整性越高，故视频时长与播放权重成正比；视频文件大小越小，表明待分享视频的压缩程度越高，故视频文件大小与播放权重成反比。此外比较相似度、当前时间、视频时长和视频文件大小所占的播放权重比例可以根据需求设置。最后待分享视频的播放权重值与待分享视频封装在一起，共同构成封装节目流，在服务器接收到该包含播放权重值的封装节目流时，服务器根据播放权重值对待播放视频和已上传未播放视频进行播放权重值降序排序，以形成等待队列。
具体地，步骤S32为：根据 WP=S*（（T-T0）/1000）*(F/L)，获取待分享视频的播放权重值，其中WP为播放权重值，S为比较相似度，T为当前时间，T0为预设历史时间，F为视频文件大小，L为视频时长。
当前时间和预设历史时间均为UTC(Coordinated Universal Time，协调世界时)时间，视频文件大小的单位为MB，视频时长的单位为分钟，预设历史时间可以为1970/1/1。从上述权重（即WP）公式可知，S、(F/L)和（（T-T0）/1000）对WP的变化影响程度一致，从单个参数分析，比较相似度S对WP的影响程度远大于当前时间T的影响程度，比较相似度S对WP的影响程度也大于视频文件大小F和视频时长L的影响程度。
在本实施例中，引入了待分享视频的播放权重值，以利于服务器根据待分享视频文件的播放权重值对播放的视频进行排序，从而使服务器向个预设频点下发的视频更贴近于用户的需求；同时也提供了一种简单可行的播放权重计算方式，综合考虑了视频文件本身参数、时间参数、流行因素而得出播放权重值，使播放权重值更能真实反映用户的实际观影需求。
本发明还提供一种视频分享系统，参照图1，在视频分享系统第一实施例中，视频分享系统包括多个智能电视100和与智能电视100连接的服务器200，
智能电视100包括：
获取模块10，用于获取服务器中已上传视频文件的文件名列表，其中文件名列表包括已播视频文件名和未播视频文件名；
智能电视100通过HFC(Hybrid Fiber－Coaxial, 混合光纤同轴电缆网)网络400与服务器200连接，可选地，服务器200与HFC网络400之间还连接有复用器300。服务器200依次将未播放的封装节目流（Transport Stream，传输流）传入到复用器300，然后复用器300将该未播放的封装节目流传入HFC网络400，并基于HFC网络400下发到各个预设频点(预设频点都是固定频点)以供智能电视100搜索预设频点观看节目，然后对该下发过的封装节目流设置已播放属性，即该封装节目流的文件名已经成为已播视频文件名，对应的，保存在服务器200但未下发预设频点的封装节目流的文件名即为未播视频文件名，已播视频文件名和未播视频文件名共同构成文件名列表。
获取模块10获取服务器上已上传文件的文件名列表，解析获取文件名列表中的已播视频文件名和未播视频文件名，以与待分享视频的文件名进行比较。
比较模块20，用于比较智能电视待分享视频的文件名与文件名列表，获取待分享视频文件名与文件名列表的相似度，其中将待分享视频文件名与文件名列表的相似度作为比较相似度；
用户可通过对智能电视输入操作指令以选择并确定待分享视频，比较模块20获取待分享视频的文件名，将待分享文件名与文件名列表中的已播视频文件名和未播视频文件名进行比较，综合得出待分享视频文件名和文件名列表的相似度，即综合得出比较相似度，该比较相似度反映出待分享视频文件名与文件名列表中各视频文件名的相似程度。
封装模块30，用于若比较相似度小于相似度阈值，则将待分享视频封装成封装节目流；
发送模块40，用于将该封装节目流发送至服务器；
相似度阈值可在智能电视出厂时设置，也可以是用户自行设置的，例如相似度阈值为80%。当比较相似度大于相似度阈值时，表明此时的待分享视频的文件名与服务器上已上传视频的文件名基本相同，也即待分享视频与服务器上已上传视频很可能是相同的，所以封装模块30对此时的待分享视频不作分享、不发给服务器；当比较相似度小于相似度阈值时，表明此时的待分享视频的文件名与服务器上已上传视频的文件名不相同，也即待分享视频与服务器上已上传视频很可能是不一样的，所以为了丰富服务器上视频的多样性，封装模块30将待分享视频封装成封装节目流，然后发送模块40将封装的封装节目流发送至服务器以供服务器将接收的封装节目流下发至处于各个预设频点，从而其它智能电视搜索预设频点观看视频节目。
播放模块50，用于通过HFC网络接收并播放预设频点上服务器下发的封装节目流。
服务器200用于：向智能电视发送已上传视频文件的文件名列表；并在接收到智能电视发送的封装节目流时，通过HFC网络将该封装节目流下发至各个预设频点。
可选地，服务器200依次将未播放的封装节目流传入复用器300，并基于HFC网络400下发到各个预设频点，并对下发过的封装节目流设置已播放属性。
在本实施例中，通过获取模块10获取与服务器已上传视频文件的文件名列表，比较模块20比较智能电视待分享视频的文件名与所述文件名列表，获取比较相似度；若比较相似度小于相似度阈值，则封装模块30将待分享视频封装成封装节目流，发送模块40将该封装节目流发送至服务器以供服务器将接收的封装节目流下发至处于各个预设频点，对应的播放模块50用于通过HFC网络接收并播放预设频点上服务器下发的封装节目流，从而实现用户后台分享自己的影片（即待分享视频），通过智能电视所连接的同轴电缆传输分享的视频到预设频点以实现直播频道观看，从而无需互联网也可以观看其他人分享的视频，进而解决了智能电视因带宽问题出现视频卡顿、影响观影效果的问题。从某种角度说，利用由智能电视、服务器和HFC网络替代了互联网，通过智能电视间的视频分享替代了互联网上的视频分享。
进一步地，在本发明视频分享系统第一实施例的基础上，提出视频分享系统第二实施例，在第二实施例中，智能电视还包括：
校验模块60，用于根据预设校验算法对待分享视频进行校验以获取第一校验码，并将该第一校验码封装到封装节目流中，以供服务器比对基于预设校验算法校验封装节目流中待分享视频所得的第二校验码和第一校验码，服务器仅在第一校验码和第二校验码匹配时保存接收到的封装节目流作为未播放封装节目流。
智能电视在确定待分享视频后，校验模块60根据预设校验算法对待分享视频进行校验，获取第一验证码，并将第一校验码封装到封装节目流中以一并发送至服务器；服务器在接收到智能电视发送的封装节目流后，解析出待分享视频和第一验证码，然后基于预设校验算法对解析出的待分享视频进行校验，获得第二验证码，然后服务器比较第一校验码和第二校验码，当第一校验码和第二校验码相同或匹配时，即待分享视频在上传过程中无数据损失，服务器保留当前接收的待分享视频；当第一校验码和第二校验码不相同或不匹配时，表明待分享视频在上传过程中很可能出现了数据损失，服务器丢弃当前待分享视频；从而有利于服务器对上传的待分享视频是否出现数据损失进行校验，避免服务器保留和下发已经出现数据损失的待分享视频，提高了待分享视频分享的有效性。
进一步地，在本发明视频分享系统第一实施例的基础上，提出视频分享系统第三实施例，在第三实施例中，比较模块20包括：
分词单元21，用于根据预设分词算法，将待分享视频的文件名分词为多个单词以形成第一词组、将文件名列表中多个文件名分词为多个单词以形成对应数量的第二词组；
次数获取单元22，用于获取第一词组中的单词个数并统计第二词组的词组个数，其中将第一词组单词个数作为第一单词数，将第二词组的词组个数作为第二词组数；
单词比较单元23，用于将第一词组中单词逐个与各个第二词组中单词进行比较，获取第一词组与各个第二词组具有相同单词的同词个数；
计算单元24，用于根据第一单词数、第二词组数和所有对应的同词个数，计算得出比较相似度。
本发明可适用于英文文件名、中文文件名和中英文混合文件名的分词，由于在英文的行文中，单词之间是以空格作为自然分界符的，故而英文文件名的分词较为简单，不做详细解释；中英文混合文件名分词时主要是先将中文和英文区分，并分别对中文和英文进行分词；而中文只有字、句和段能通过明显的分界符来简单划界，唯独词没有一个形式上的分界符，所以中文的分词较为复杂，以下主要解释中文分词算法，中文分词算法将一个汉字序列切分成一个一个单独的词，也就是将连续的汉字序列按照一定的规范重新组合成词序列的过程。当然，本发明的分词算法不限定于中文分词算法。
中文分词算法一般包括字符匹配法、理解法等，字符匹配法是按照一定的策略将待分析的汉字串（相当于待分享视频文件名）与一个“充分大的”机器词典（相当于文件名列表中文件名）中的词条进行配，若在词典中找到某个字符串，则匹配成功；理解法是通过让计算机模拟人对句子的理解，达到识别词的效果，其基本思想就是在分词的同时进行句法、语义分析，利用句法信息和语义信息来处理歧义现象；其中匹配法应用较为广泛，本实施例应用匹配法，以下以匹配法解释说明本发明实施例。
基于设定的汉语规范将待分享视频的文件名分词为多个单词，具体地可以是：优先在待分享视频的文件名中识别和切分出一些带有明显特征的词（例如“是”、“有”等动词、数字与汉字交界的词、英文与汉字交界的词等），以这些词作为断点，可将原文件名分为较小的汉字串，然后有序拆分汉字串去匹配预设的汉字词库，文件名中与汉字词库相同的拆分后汉字串作为一个单词。
例如，待分享视频的文件名为“2008年北京奥运年鸟巢体育馆开幕式现场直播”，则通过分词算法可分词为“2008”，“年”，“北京”，“奥运会”，“鸟巢”，“体育馆”，“开幕式”，“现场”，“直播”九个单词，这九个单词共同组成第一词组，即第一词组是这九个单词的集合，将第一词组中的单词个数作为第一单词数，即第一单词数为9。
文件名列表中包括三个已分享视频的文件名，分别是文件名一、文件名二和文件名三，文件名一是“2008年北京奥运会”，对应的第二词组A为{“2008”，“年”，“北京”，“奥运会”}；文件名二是“北京奥运会比赛现场”，对应的第二词组B为｛“北京”，“奥运会”，“比赛”，“现场”｝；文件名三是“2008奥运会开幕式”，对应的第二词组C为｛“2008”，“奥运会”，“开幕式”｝，进而得出第二词组的个数（即第二词组数）为3。
然后将第一词组中的单词逐个与第二词组A中的单词进行比较，相同的单词有“2008”、“年”、“北京”和“奥运会”四个相同的单词，所以同词个数A为4；同理第一词组与第二词组B的同词个数B为3，第一词组与第二词组C的同词个数为3。然后根据第一单词数（值为9）和同词个数A（值为4），求出第一词组与第二词组A的初级相似度A，根据第一单词数（值为9）和同词个数B（值为3），求出第一词组与第二词组B的初级相似度B，根据第一单词数（值为9）和同词个数C（值为3），求出第一词组与第二词组C的初级相似度C；如初级相似度A为 = ，初级相似度B为 = ，初级相似度C为 = 。
最后根据初级相似度A、初级相似度B、初级相似度C和第二词组数，计算三个初级相似度的平均值，该平均值即为待分享视频文件名与文件列表的比较相似度，如比较相似度=（ + + ）/3=1/48。
在本实施例中，根据待分享视频的第一单词数、文件名列表中的第二词组数和所有对应的同词个数，计算得出比较相似度提供了一种简单、可行、准确的比较相似度计算算法， 进一步提升了判断待分享视频是否上传服务器的准确性。
进一步地，在本发明视频分享系统第一实施例的基础上，提出视频分享系统第三实施例，在第四实施例中，封装模块30包括：
参数获取单元31，用于若比较相似度小于相似度阈值，获取当前时间、待分享视频的视频时长和视频文件大小；
权重获取单元32，用于根据比较相似度、当前时间、视频时长和视频文件大小，获取待分享视频的播放权重值；
封装单元33，用于将播放权重值和待分享视频封装成封装节目流；
对应的，服务器还用于：
接收到封装节目流后依据播放权重对各未播放封装节目流进行排序并依据排序顺序下发。
当比较相似度小于相似度阈值时表明待分享视频在服务器上存在的可能性较小，进而参数获取单元31获取当前时间、待分享视频的视频时长和视频文件大小，然后权重获取单元32根据比较相似度、当前时间、视频时长和视频文件大小，获取待分享视频的播放权重值，其中比较相似度越高，表明待分享视频与服务器上其它用户上传的视频相关度越高，即表明该待分享视频越流行，故比较相似度与播放权重成正比；当前时间距离预设历史时间越远，表明待分享视频越新颖，故当前时间越靠后播放权重越大；视频时长越长，表明待分享视频的完整性越高，故视频时长与播放权重成正比；视频文件大小越小，表明待分享视频的压缩程度越高，故视频文件大小与播放权重成反比。此外比较相似度、当前时间、视频时长和视频文件大小所占的播放权重比例可以根据需求设置。最后封装单元33将待分享视频的播放权重值与待分享视频封装在一起，共同构成封装节目流，在服务器接收到该包含播放权重值的封装节目流时，服务器根据播放权重值对待播放视频和已上传未播放视频进行播放权重值降序排序，以形成等待队列。
在本实施例中，引入了待分享视频的播放权重值，以利于服务器根据待分享视频文件的播放权重值对播放的视频进行排序，从而使服务器向个预设频点下发的视频更贴近于用户的需求；同时也提供了一种简单可行的播放权重计算方式，综合考虑了视频文件本身参数、时间参数、流行因素而得出播放权重值，使播放权重值更能真实反映用户的实际观影需求。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质（如ROM/RAM、磁碟、光盘）中，包括若干指令用以使得一台终端设备（可以是手机，计算机，服务器，空调器，或者网络设备等）执行本发明各个实施例的方法。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
