Description

一种多屏播放的电视机及其多屏播放方法
技术领域
本发明涉及电视技术领域，特别涉及一种多屏播放的电视机及其多屏播放方法。
背景技术
目前电视机越做越大，分辨率也越来越高。当屏幕从较小的 32 寸发展到主流的 55 寸，甚至更大至 100 多寸时，分辨率也从原有的 1366 × 768 发展到了 3840 × 2160 ，甚至更高的 8K 。
但是，现有的电视机即使屏幕再大也只能一个屏幕显示单一通道的视频内容。而各个家庭成员对电视节目的观影需求不同，电视机不能同时显示不同视频信号的节目。作为主要的娱乐休闲电子产品和非个人独占设备，现有电视机的一块屏幕显示唯一的视频内容难以同时满足多用户的不同观看需求。
因而现有技术还有待改进和提高。

具体实施方式
本发明提供一种多屏播放的电视机及其多屏播放方法，适用与图像显示领域，如电视领域，电脑显示器等。将一块电视屏幕分为多个子屏幕，每个子屏幕显示各用户喜欢看的内容，可单独播放子屏幕对应的音频，用户还能对自己观看的子屏幕进行操作选择，以达到在一块电视主屏幕上，不同用户同时观看各自的子屏幕且互不影响。为使本发明的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。 应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
请参阅图 1 ， 本发明实施例提供的多屏播放的电视机 预先设置若干个子屏幕和端子接口，每个子屏幕配置一对耳机。所述 电视机包括 处理模块 10 、控制模块 20 、显示模块 30 和声音模块 40 。所述处理模块 10 对采集 若干个端子接口输入的视频信号，进行匹配解码处理、图像处理和音频处理后分别生成若干组图像子信号和声音子信号。显示模块 30 将每组中的图像子信号混合叠加后传输至对应的子屏幕显示。声音模块 40 将每组中的声音子信号编码后蓝牙发送给对应的耳机播放。所述控制模块 20 根据遥控信号控制显示模块 30 的显示效果和系统调配 。每个端子接口与一个子屏幕对应，端子接口输入的视频信号在对应的子屏幕上显示、且声音在对应的耳机中播放。若某端子无视频信号输入，则对应的子屏幕上无显示。
本实施例中，所述处理模块 10 包括信号采集单元 110 、信号解码单元 120 、图像处理单元 130 和音频处理单元 140 。
所述信号采集单元 110 采集电视机的若干个端子接口输入的视频信号，并对这若干个视频信号进行阻抗匹配，使其成为系统能够正常接收的对应的若干个子屏信号后传输给信号解码单元 120 。所述视频信号包括 CVBS （ Composite Video Broadcast Signal ，复合视频广播信号）信号、 YUV ( 亦称 YCrCb) 信号、 HDMI （ High － Definition Multimedia Interface ）信号、 RF （射频）信号、 VGA(Video Graphics Array) 信号等。如图 2 所示，基于这些不同格式的视频信号会分别输入到一个子屏幕中显示，在出厂前预先设置每个子屏幕显示哪个端子接口输入的视频信号。如第一端子接口（如在电视机侧面从上至下数的第一个端子接口）输入 CVBS 信号，经过信号采集单元 110 处理后变成第一子屏信号；第二端子接口输入 YUV 信号变成第二子屏信号；依次类推直至第 n 端子接口输入的 n 信号变成第 n 子屏信号。端子接口的个数与子屏幕的个数相同，端子接口外接哪种信号由用户决定，此处对其不作限制。电视机上的端子接口为现有技术。
所述信号解码单元 120 采用了高性能的具有多通道解码能力（每个通道分别同时解码一种信号）的电视芯片，能够对输入的若干个子屏信号进行多通道解码，生成系统能够识别的对应的若干组图像子信号和声音子信号、并将解码出来的图像子信号和声音子信号分别传输给图像处理单元 130 和音频处理单元 140 。第一子屏信号经过信号解码单元 120 处理后变成第一图像子信号和第一声音子信号；同理，第二子屏信号、第 n 子屏信号也变成对应的图像子信号和声音子信号，如图 3 所示。
所述图像处理单元 130 也具备多通道处理能力，对相应的图像子信号进行分辨率放大或者缩小处理，使其成为符合该子屏幕显示所需的分辨率；同时还对子屏幕的显示位置进行计算，使图像子信号显示在正确的屏幕上。
需要理解的是，只要端子接口外接设备，就实时采集其输入的视频信号，但具体显示哪几个视频信号，由图像处理单元 130 根据用户选屏决定。如设置了 4 个子屏幕，有 4 个端子接口输入 4 种视频信号，这 4 种视频信号均会进行上述的采集和解码处理。若用户选择分屏显示，则 4 种视频信号分别传输至对应的子屏幕进行显示。若用户选择显示全屏，在 4 种视频信号均输入时，图像处理单元 130 处理第一端子接口输入的视频信号后给显示模块显示；只有一个端子接口输入视频信号时，图像处理单元 130 处理该端子接口输入的视频信号后、输出给显示模块显示。若仅 2 个端子接口外接设备，则这 2 个端子接口对应的子屏幕显示对应视频信号，其他子屏幕无显示。在具体实施时，用户也可通过遥控器选择全屏显示哪个端子接口的视频信号。
图像处理单元 130 根据预设顺序（如按照从左至右、从上之下的顺序）将图像子信号与相应的子屏幕一一对应，并对每个子屏幕分配对应的图像子信号 ( 即将图像子信号中的各个像素点与对应的显示位置中的坐标点相对应，以确定哪个坐标点显示哪个像素点 ) 。假设如图 4 所示，当前所展示的子屏幕的个数为 4 个，根据预设顺序分别为第一子屏幕、第二子屏幕、第三子屏幕、第四子屏幕。第一子屏幕显示第一端子接口输入的视频信号（以此类推）。整体屏幕的分辨率为 3840*2160 ，图像处理单元 130 每个子屏幕进行均分，则每个子屏幕的分辨率大小为： 1920*1080 。对应在屏幕上的坐标位置如图 4 所示。则输入的 4 路图像子信号需要进行分辨率的放大或者缩小处理，如果图像子信号的分辨率小于 1920*1080 ，需要将其放大成 1920*1080 分辨率的图像信号；反之则缩小为 1920*1080 分辨率，使输入的图像子信号满足子屏幕分辨率的需求。需要理解的是，所述电视机的子屏幕预先划分为 n 个，即最多能同时显示 n 个屏。但实际观看时，用户可能使用全屏，全屏则无需计算坐标（相当于计算屏幕四个顶点的坐标，该坐标已知，因此无需计算）；若分辨率不满足全屏要求则进行对应的缩放处理，若满足则不处理。
另外，图像处理单元 130 还会对图像子信号进行图像处理，包括画质调整（包括清晰度、对比度、图像颜色等方面的处理）和运动补偿等图像处理，以达到更好的图像效果。图像处理单元 130 将处理后的各子屏幕的图像子信号传输给显示模块 30 。
所述显示模块 30 根据显示位置对各图像子信号进行混合叠加，具体为将各图像子信号各取一帧，将取出的各图像子信号的每个像素点值存储在一个对应的二维矩阵里，矩阵的大小对应各图像的分辨率。然后将各图像子信号对应的二维矩阵按照电视需要显示的位置进行叠加，使各个二维矩阵变为一个供全屏幕显示的总矩阵。该总矩阵的大小为电视实际屏幕的分辨率。这样总矩阵里每个元素的值就对应电视的每个像素点值，从而实现图像信号和电视屏幕的匹配。最后，显示模块 30 再将总矩阵转化为供电视屏幕能够显示的格式信号 ( 比如 V-by-OneHS 信号 ) ，并输出至显示屏的对应区域进行显示。图像子信号被混合叠加成全屏的信号，由于将二维矩阵与需要显示的位置进行对应，只有对应的坐标点才会显示对应的像素点值，这样即可避免混合后显示错误的画面。
图像子信号进行处理的同时，声音子信号也进行相应的处理。信号解码单元 120 输出各声音子信号至音频处理单元 140 进行相应的处理。所述音频处理单元 140 也具有多通道处理能力，处理主要包括声音部分的高音、低音的加强或减弱，环绕声、立体声等各种声音模式的处理，以及声音功率放大输出曲线的调整。音频处理单元 140 处理后的声音子信号传输给声音模块 40 。
由于在同一显示屏上显示不同的视频，每个子屏幕对应的声音也不相同，现有电视机中唯一的喇叭已不能满足音频需求。为了使每个用户都能听到自己所用子屏幕的声音，且每个子屏幕的声音互不干扰。本实施例采用与电视机配对的若干个耳机来收听。所述耳机可为蓝牙耳机，每对耳机中的左耳机和右耳机可通过数据线连接在一起，方便用户佩戴。也可将左耳机和右耳机分开并标号区分，如 1L 表示第一子屏幕的左耳机， 3R 表示第三子屏幕的右耳机；这样一对耳机可同时供两位用户使用。
则对应地，所述声音模块 40 内需设置若干个蓝牙模块，蓝牙模块的个数与子屏幕的个数、耳机的个数相同。每对耳机与一个蓝牙模块配对，如图 5 所示。各蓝牙模块对接收的对应的声音子信号后进行重新编码后、采用蓝牙方式发送给相应的耳机。耳机对接收的编码后的声音子信号进行解码，发出对应的声音供用户收听。从而实现个各子屏幕的独立收听。
当用户选择全屏显示，则只有一个声音子信号，其可以通过第一耳机播放；也可以在用户选择电视播放时，由电视机内现有的功放模块进行功率放大后、传输至电视机现有的喇叭播放。若有 2 个以上的声音子信号，则只有第一端子接口输入的视频信号处理后获得声音子信号、能通过第一耳机或喇叭播放 。
如图 6 所示，假设第一端子接口至第四端子接口分别输入 CVBS 信号、 HDMI 信号、 RF 信号、 YUV 信号。先通过信号采集单元 110 内的各通道分别进行采集、阻抗匹配；再通过信号解码单元 120 内的各通道分别解码。生成的 CVBS 图像子信号、 HDMI 图像子信号、 RF 图像子信号、 YUV 图像子信号传输至图像处理单元 130 中的对应通道内进行图像处理后，发送至显示模块 30 混合叠加，最后输出至显示屏的对应子屏幕进行显示。 CVBS 声音子信号、 HDMI 声音子信号、 RF 声音子信号、 YUV 声音子信号传输至音频处理单元 140 的各通道中进行声音处理后，再传输至声音模块 40 的对应蓝牙模块内进行编码，采用蓝牙方式发送给相应的耳机。
本实施例中，处理模块 10 完成音视频信号的相应处理和播放显示，控制模块 20 完成相应的控制操作。所述控制模块 20 包括遥控单元 210 、调度单元 220 和 UI 单元 230 。
所述遥控单元 210 用于实现多用户对各子屏幕用户界面的操控。现有的电视机只有一个遥控器来对进行操作，本实施例为了实现多用户操作，每个子屏幕配置一个红外遥控器，且每个遥控器针对各子屏幕同样的功能指令、所发出的遥控按键的键值不同，这样即可通过独立的遥控器分别控制一个子屏幕，即使进行相同的遥控操作，子屏幕之间也不会相互影响。遥控单元 210 识别接收的红外的遥控信号属于哪个子屏幕，并解析成对应的遥控指令发送至 UI 单元 230 执行相应的操作。
当遥控单元识别遥控指令为内存操作指令时（如涉及内存清理、或内存分配、或内存消耗查询显示等），还可直接发送至调度单元 220 进行相应的内存处理。如为内存清理指令时，调度单元 220 即可进行内存清理，以腾出更多的内存，加快系统运行。
基于电视机分为若干个子屏幕，为了使每个屏幕都能独立操作，通过 UI 单元 210 来控制和协调每个子屏幕的人机交互界面。所述 UI 单元 210 用于显示各子屏幕的用户菜单；其还与调度单元 220 通信，发送用户对用户菜单的操作指令给调度单元 220 ，以便调度单元 220 进行操作指令的分配和执行；调度单元 220 还将执行结果反馈至 UI 单元 210 ， UI 单元 210 控制显示模块显示对应的执行操作。
所述调度单元 220 起到系统调配（中枢调度）作用，其根据每个子屏幕的运行需求，对解码单元（包括本实施例中的信号解码单元和电视机中其他现有的解码单元）、 CPU 、 GPU （ Graphics Processing Unit ，图形处理器，属于图像处理单元）、内存等硬件资源进行分配和调度；具体包括对各种视频信号硬件解码资源需求的调配，对 CPU 处理需求的能力均衡使用，对各信号传输通道所需内存的申请、分配和管理等。
基于上述的多屏播放的电视机， 本发明实施例还提供一种 多屏播放的电视机的多屏播放方法，如图 7 所示，具体包括：
S100 、处理模块采集若干个端子接口输入的视频信号，进行匹配解码处理、图像处理和音频处理后分别生成若干组图像子信号和声音子信号；
S200 、显示模块将每组中的图像子信号混合叠加后传输至对应的子屏幕显示；声音模块将每组中的声音子信号编码后蓝牙发送给对应的耳机播放；
S300 、控制模块根据遥控信号控制显示模块的显示效果和系统调配。
其中，所述步骤 S200 具体包括：
步骤 201 、信号采集单元采集电视机若干个端子接口输入的视频信号，并对若干个视频信号进行阻抗匹配、生成对应的子屏信号后传输给信号解码单元；
步骤 202 、信号解码单元对若干个子屏信号进行多通道解码，生成对应的若干组图像子信号和声音子信号，并将图像子信号传输给图像处理单元、将声音子信号传输给音频处理单元；
步骤 203 、图像处理单元对图像子信号进行图像处理和分辨率的缩放处理，计算各子屏幕的显示位置、并对每个子屏幕分配对应的图像子信号；
步骤 204 、音频处理单元对声音子信号进行音量调整和声音功率放大输出曲线的调整。具体请参见上述实施例。
所述步骤 S300 具体包括：
步骤 301 、遥控单元识别遥控信号所属的子屏幕，并解析成对应的遥控指令发送至 UI 单元执行相应的操作；
步骤 302 、 UI 单元显示各子屏幕的用户菜单，发送所述操作对应的操作指令给调度单元；
步骤 303 、调度单元根据操作指令进行对应的系统调配和执行、并将执行结果反馈至 UI 单元；
步骤 304 、 UI 单元控制显示模块显示对应的执行操作。
综上所述，本发明采用多通道和多任务技术，在一块电视屏幕上分多屏显示，每个子屏幕显示的内容根据用户的选择来进行显示，每个子屏幕可以通过与其匹配的遥控器进行操控；且每个子屏幕配置不同的声音输出，各子屏幕的声音能够通过与其对应的蓝牙模块传输到对应的耳机播放。用户无需购买多台电视来满足多用户观看需求，多用户可以同时使用一台电视机观看自己喜欢的内容，满足各个用户的个性观看需求，为用户节约了购买成本。
可以理解的是，对本领域普通技术人员来说，可以根据本发明的技术方案及其发明构思加以等同替换或改变，而所有这些改变或替换都应属于本发明所附的权利要求的保护范围。
