Description

智能电视播放方法及智能电视
技术领域
本发明涉及电视技术领域，尤其涉及一种智能电视播放方法及智能电视。
背景技术
目前，采用Android操作系统的电视，既具有普通电视功能，也可以提供类似电脑的某些功能。
然而，在使用Android TV看电视时，虽然电视的高亮度和艳丽的色彩完全可以满足远距离观看电视或其他视频播放的需要；但是，如果用户需要进行类似电脑的近距离操作时，如看文档、浏览网页等，Android TV的高亮度会对用户的眼睛造成很大刺激，因此，不利于用户近距离长时间操作电视。
另外，在实现类似电脑功能时，由于电脑图像显示对灰阶要求较高，类似于PC主机，灰阶的输出为0-255。在灰阶输出为0的情况下，屏幕显示全黑画面；在灰阶为255的情况下，屏幕显示全白画面。而电视则不同，电视的灰阶范围是16-235，当电视接收到的信号为16灰阶时，电视将其还原成白色；当电视接收到的信号为235灰阶时，屏幕显示全白画面。
电视的输入设备，比如有线电视信号、DVD影碟机等输出的也是16-235的灰阶信号。如果电视接收到低于16的灰阶信号，该信号将会被认为是干挠信号而不被显示；如果电视接收到高于235的信号，大部分液晶电视则只能做削波处理，即将接收到的信号仍当做235灰阶信号来处理，中间的过渡信号将全部损失。
在ANDROID TV实现类似电脑功能时，由于实际的视频内容仍需要按照0-255灰阶信号的色彩输入电视，而电视会按照16-235的灰阶信号接收，则会出现上述的灰阶损失，使得大约13%的色彩变化将不会被显示，由此产生色彩失真。因此，现有技术有待改进。

如前所述，Android系统的电视，既具有普通电视功能，也可以提供类似电脑的某些功能。但是在实现电脑功能时会产生图像色彩失真的问题，本实施例为了提高智能电视在实现电脑功能时的播放显示效果，在智能电视中设置有两种播放模式：电脑模式和电视模式。
在电脑模式下，智能电视可以播放非视频内容，或者以非全屏显示的方式播放视频内容；在电视模式下，智能电视可以进行普通电视的电视播放功能，还可以采用非全屏显示方式播放从网络下载的视频流或者本地存储的视频文件。
当智能电视启动Android系统后，获取当前播放的内容，判断当前播放的内容是否为全屏显示播放的视频内容，如果是，则选择播放模式为电视模式；如果当前播放的内容不是视频内容或者是非全屏显示播放的视频内容，则选择播放模式为电脑模式。
上述视频内容可以是来自网络的视频流，也可以是本地存储的视频文件。
上述播放内容的判断具体可以通过智能电视的MCU来判断。
步骤S102，以所述对应的播放模式播放当前内容。
当智能电视通过判断选取相应的播放模式后，则以对应的播放模式来播放当前内容。
具体地，当所述播放模式为电视模式时，智能电视的MCU控制电视的图像处理电路工作，并设置电视的视频播放相关参数，具体为：灰阶采取电视中的16-235灰阶，伽玛值设定为2.4，亮度设置在300cd/m2以上；从上述参数设置可以看出，设置的电视灰阶较低，伽玛值较高，亮度也较高，这样可以满足用户远距离观看视频。
当所选取的播放模式为电脑模式时，智能电视的MCU控制电视的图像处理电路不工作，即关闭电视的图像处理电路，将电视作为显示器使用，关闭电视的图像处理电路，直接采用电视的显存芯片，并采取点对点的图像显示方式，同时调用存储器中存储的各种参数，其具体参数如下：灰阶采取电视中的0-255灰阶，伽玛值设置为2.2，亮度设置在300cd/m2以下，从上述参数设置可以看出，设置的电视灰阶数较高，伽玛值较低，亮度也较低，这样可以满足用户近距离观看文档。
具体地，如图2所示，上述步骤S101中根据当前播放内容，或者根据当前播放的视频内容及屏幕显示状态，选择对应的播放模式的步骤可以包括：
步骤S1011，判断当前播放内容是否为非视频内容；若是，则进入步骤S1014；否则，进入步骤S1012；
步骤S1012，判断当前播放的视频内容是否为全屏显示；若是，则进入步骤S1013；否则，进入步骤S1014；
步骤S1013，将电视播放模式选择切换为电视模式；
步骤S1014，将电视播放模式选择切换为电脑模式；
作为一种实例，在判断当前播放的视频内容是否为全屏显示的视频内容时，可以采用以下方式：
首先判断智能电视当前是否与网络相连，如果目前智能电视与网络相连，且有视频流传输至电视中，则判断电视当前播放的内容为视频内容；
然后，判断当前播放的视频内容是否为全屏显示，如果为全屏显示，则将电视播放模式设置为电视模式。
如果电视当前未与网络相连，则判断电视当前是否有视频文件播放，如有视频文件播放，则判断电视当前播放的视频内容是否全屏显示，如果为全屏显示，则将电视播放模式设置为电视模式；
如电视未播放视频内容或虽播放视频内容，然而未全屏显示，则将电视播放模式设置为电脑模式。
本实施例通过上述方案，根据智能电视当前播放内容及屏幕显示状态，选择对应的电脑模式或电视模式播放相应的内容，避免了具有类似Android系统的智能电视在实现电脑功能时造成图像色彩失真的问题，提高了智能电视在实现电脑功能时的播放显示效果。
如图3所示，本发明第二实施例提出一种智能电视播放方法，在上述第一实施例的基础上，在上述步骤S101之前还包括：
步骤S100，检测智能电视是否启动预定的操作系统。
本实施例与上述实施例的区别在于，本实施例还包括检测智能电视是否启动预定的操作系统的方案。
以预定的操作系统为Android系统为例，本实施例通过判断是否启动init进程来判断是否启动Android系统。
init进程是一个由内核启动的用户级进程。内核自行启动之后，就通过启动一个用户级程序init的方式，来完成引导进程。init进程始终是Android系统启动后的第一个进程；电视的MCU判断init进程启动后，则认为Android系统启动。
本实施例通过上述方案，实现了智能电视Android系统的启动检测，在Android系统后，根据智能电视当前播放内容及屏幕显示状态，选择对应的电脑模式或电视模式播放相应的内容，避免了具有类似Android系统的智能电视在实现电脑功能时造成图像色彩失真的问题，提高了智能电视在实现电脑功能时的播放显示效果。
如图4所示，本发明第一实施例提出一种智能电视，包括：选择切换模块401以及播放模块402，其中：
选择切换模块401，用于在智能电视启动预定的操作系统后，根据当前播放内容，或者根据当前播放的视频内容及屏幕显示状态，选择对应的播放模式；
播放模块402，用于以所述对应的播放模式播放当前内容。
本实施例智能电视采用Android系统或类似Android系统的操作系统，在此以Android系统举例说明。该智能电视可以是具有网络功能的网络电视。
如前所述，Android系统的电视，既具有普通电视功能，也可以提供类似电脑的某些功能。但是在实现电脑功能时会产生图像色彩失真的问题，本实施例为了提高智能电视在实现电脑功能时的播放显示效果，在智能电视中设置有两种播放模式：电脑模式和电视模式。
在电脑模式下，智能电视可以播放非视频内容，或者以非全屏显示的方式播放视频内容；在电视模式下，智能电视可以进行普通电视的电视播放功能，还可以采用非全屏显示方式播放从网络下载的视频流或者本地存储的视频文件。
当智能电视启动Android系统后，获取当前播放的内容，选择切换模块401判断当前播放的内容是否为全屏显示播放的视频内容，如果是，则选择播放模式为电视模式；如果当前播放的内容不是视频内容或者是非全屏显示播放的视频内容，则选择播放模式为电脑模式。
上述视频内容可以是来自网络的视频流，也可以是本地存储的视频文件。
上述播放内容的判断具体可以通过智能电视的MCU来判断。
当智能电视通过判断选取相应的播放模式后，播放模块402则以对应的播放模式来播放当前内容。
具体地，当所述播放模式为电视模式时，智能电视的MCU控制电视的图像处理电路工作，并设置电视的视频播放相关参数，具体为：灰阶采取电视中的16-235灰阶，伽玛值设定为2.4，亮度设置在300cd/m2以上；从上述参数设置可以看出，设置的电视灰阶较低，伽玛值较高，亮度也较高，这样可以满足用户远距离观看视频。
当所选取的播放模式为电脑模式时，智能电视的MCU控制电视的图像处理电路不工作，即关闭电视的图像处理电路，将电视作为显示器使用，关闭电视的图像处理电路，直接采用电视的显存芯片，并采取点对点的图像显示方式，同时调用存储器中存储的各种参数，其具体参数如下：灰阶采取电视中的0-255灰阶，伽玛值设置为2.2，亮度设置在300cd/m2以下，从上述参数设置可以看出，设置的电视灰阶数较高，伽玛值较低，亮度也较低，这样可以满足用户近距离观看文档。
具体地，如图5所示，所述选择切换模块401包括：判断单元4011以及选择切换单元4012，其中：
判断单元4011，用于判断当前播放内容是否为非视频内容，以及当前播放内容为视频内容时，判断当前播放的视频内容是否为全屏显示；
选择切换单元4012，用于当所述判断单元判断当前播放内容为非视频内容时，或者当所述判断单元判断当前播放内容为视频内容，且当前播放的视频内容未全屏显示时，将电视播放模式选择切换为电脑模式；以及当所述判断单元判断当前播放内容为视频内容，且当前播放的视频内容为全屏显示时，将电视播放模式选择切换为电视模式。
作为一种实例，在判断当前播放的视频内容是否为全屏显示的视频内容时，可以采用以下方式：
首先判断智能电视当前是否与网络相连，如果目前智能电视与网络相连，且有视频流传输至电视中，则判断电视当前播放的内容为视频内容；
然后，判断当前播放的视频内容是否为全屏显示，如果为全屏显示，则将电视播放模式设置为电视模式。
如果电视当前未与网络相连，则判断电视当前是否有视频文件播放，如有视频文件播放，则判断电视当前播放的视频内容是否全屏显示，如果为全屏显示，则将电视播放模式设置为电视模式；
如电视未播放视频内容或虽播放视频内容，然而未全屏显示，则将电视播放模式设置为电脑模式。
本实施例通过上述方案，根据智能电视当前播放内容及屏幕显示状态，选择对应的电脑模式或电视模式播放相应的内容，避免了具有类似Android系统的智能电视在实现电脑功能时造成图像色彩失真的问题，提高了智能电视在实现电脑功能时的播放显示效果。
如图6所示，本发明第二实施例提出一种智能电视，在上述第一实施例的基础上，还包括：
检测模块400，用于检测智能电视是否启动预定的操作系统。
本实施例与上述实施例的区别在于，本实施例还包括检测智能电视是否启动预定的操作系统的方案。
以预定的操作系统为Android系统为例，本实施例检测模块400通过判断是否启动init进程来判断是否启动Android系统。
init进程是一个由内核启动的用户级进程。内核自行启动之后，就通过启动一个用户级程序init的方式，来完成引导进程。init进程始终是Android系统启动后的第一个进程；电视的MCU判断init进程启动后，则认为Android系统启动。
本实施例通过上述方案，实现了智能电视Android系统的启动检测，在Android系统后，根据智能电视当前播放内容及屏幕显示状态，选择对应的电脑模式或电视模式播放相应的内容，避免了具有类似Android系统的智能电视在实现电脑功能时造成图像色彩失真的问题，提高了智能电视在实现电脑功能时的播放显示效果。
以上所述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流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本发明的专利保护范围内。
