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。
本发明提供一种电视图文多设备显示方法，如图1所示，示出了本发明电视图文多设备显示方法第一实施例的流程示意图，包括：
S10、获取实时接收的传输流；
所述传输流包括视频信号和图文信号，由电视机的信号接收器实时接收。一个传输流对应一帧视频图像。
S20、从所述传输流中提取出图文显示数据，并根据所述图文显示数据生成图文二维码图像；
在获取到所述传输流后，通过解析所述传输流获得对应的视频信号和图文信号。根据图文信号中的包类型从所述图文信号中提取出对应的图文显示数据，然后再根据所述提取出的图文显示数据，生成包含图文信息的图文二维码图像。
S30、在播放所述传输流对应节目的同时，动态显示所述图文二维码图像，以供至少一个移动终端录制所述图文二维码图像。
所述移动设备可以是手机、平板电脑，也可以是其他具有二维码图像处理功能的设备，且移动设备上安装有图文处理软件，所述图文处理软件能够控制图文二维码图像流的录制、解析和存储，以及解析出的图文信息在设备上的展示等。
电视机的视频信号处理器在对所述视频信号进行处理后，在电视机的显示器上播放所述视频信号对应的节目内容。与此同时，所述显示器根据所述图文显示数据中信息动态地同步显示所述图文二维码图像。
在电视机播放节目内容及显示与所述节目内容同步的图文二维码图像时，用户可通过一个或多个移动设备同时或分时，分别录制一段图文二维码图像流，其中，所述图文二维码图像流是指连续显示的一个或多个所述图文二维码图像。移动设备在录制并解析所述图文二维码图像流后，将解析获得的一组图文信息存入存储区。当用户想要查看所述图文信息时，在移动设备的显示屏上按照图文的先后顺序展示所述图文信息。
由于所述图文二维码图像在所述显示器的屏幕上占用的区域面积大小固定，且与图文在电视机上正常显示时所占用的区域面积相比要小的多，其显示及后续通过移动设备查看图文内容也不会引起当前所播放节目画面的切换，因而所述图文二维码图像可视为不影响当前所播放节目的全屏播放。
本发明提出的电视图文多设备显示方法，采用二维码图像的方式在电视机上同步显示节目对应的图文信息，且支持在一个或多个移动设备上查看所录制的图文信息的内容，在不影响电视机当前所播放节目全屏播放的情况下，实现了图文内容在一个或多个移动设备上的查看。
进一步地，基于第一实施例提出本发明第二实施例，在本实施例中，所述传输流包括视频信号和图文信号。如图2所示，上述步骤S20包括：
S21、解析所述传输流，获得视频信号和图文信号；
所述传输流中包含当前正在播放节目的节目号及与所述节目号对应的节目映射表。所述节目映射表包含所述节目号对应图文数据在所述传输流中的位置信息、所述节目号对应视频数据在所述传输流中的位置信息，可根据所述节目号对应的图文数据标识、视频数据标识来确定图文数据和视频数据的位置。在确定出视频数据和图文数据所在数据位置后，通过电视机内置的解码器解析所述视频数据和图文数据，从而获得所述传输流对应的视频信号和图文信号。
所述图文信号按照数据流类型可分为teletext数据和subtitle数据，数据流类型为teletext的数据表示覆盖全屏的图文数据，所述数据流类型为subtitle的数据表示部分覆盖到节目内容的图文数据，例如字幕。
S22、从所述图文信号中提取出图文显示数据；
所述图文信号包括3种基本类型的包，分别是页头包、普通行包、扩展包。其中，页头包包括所述图文信号所包含的所有图文的页码编号信息、显示时间点信息、显示控制信息等；普通行包包括与所述页头包中所有图文的页号对应的能够直接显示的图文内容的信息；扩展包不包括用于直接显示的图文内容信息，其包括为高级的解码器提供增强性能或提供特殊数据服务的信息。
从所述图文信号中的页头包和普通行包中提取出除控制信息之外的所有图文信息，将所提取出的图文信息存入缓存区并用页码进行标识，从而获得所述图文显示数据。其中，所述控制信息包括图文的显示时间点信息和显示控制信息。
S23、根据所述图文显示数据按页生成包含页码信息的图文二维码图像。
电视图文是由一组具有页码编号（3位页码数）的图文组成，每页的图文由24行40列的字符和图形构成。电视机根据所述图文显示数据将每页图文的内容和其对应的帧编号及页码编号信息进行编码从而生成图文二维码图像。一个图文信号包含多个图文的，对应生成相同数量的多个图文二维码图像。每一个所述图文二维码图像所包含的信息有：其对应图文信号的帧编号（与所述图文信号对应传输流的帧编号相同）、其对应图文信号所含图文的总页数、当前图文二维码图像所对应图文的页码编号、当前图文二维码图像所对应图文的内容。
本发明提出的电视图文多设备显示方法，将从所述传输流中提取出的图文显示数据按照与在电视机上正常显示图文一致的信息，按页依次生成对应的图文二维码图像，保证了所生成的图文二维码图像与每页图文的一一对应，为后续使用移动设备查看到与电视机一致的图文信息打下基础。
进一步地，基于第二实施例提出本发明电视图文多设备显示方法第三实施例，在本实施例中，上述步骤S30包括：
在播放所述视频信号对应节目内容的同时，按照页码顺序动态显示所述图文二维码图像。
电视机在所述视频信号经过视频信号处理器处理后，根据处理结果在显示器上播放相应的节目内容，与此同时，电视机根据当前节目的帧频信息刷新图文二维码图像的显示，以达到图文二维码图像与其对应节目内容的同步显示。例如，在当前播放节目的帧频为60HZ时，每秒按帧编号顺序依次显示60张节目画面，且在显示每张节目画面时根据当前节目画面所对应图文信号中的各个图文的页码编号及图文显示时间点等信息，同步显示当前节目画面对应的具有不同页码编号的所有图文二维码图像。
