Description

用电视红外接收头实现鼠标功能的方法及系统
技术领域
本发明涉及电视机的遥控控制技术，具体涉及一种用电视红外接收头实现鼠标功能的方法及系统。
背景技术
随着智能系统在电视机中的成功应用，智能电视正迅速发展起来，智能电视中的应用软件也越来越多，操作也越来越复杂，比如浏览网页、鼠标操作类游戏等，这些应用软件显然不是以往常规的功能按键的遥控器能满足的，很多时候需要有鼠标功能，甚至需要一些基本的手势功能，比如浏览网页时需要随意点击标题、需要页面滚动等，所以必须有相应的智能遥控器来实现更好的人机交互。
目前智能遥控器的种类已经很多，发射方式主要是RF，也有少部分是红外方式，但几乎所有的智能遥控器在实现鼠标等功能时都是通过主芯片的USB通道上报鼠标事件，这样必须消耗主芯片的一路USB通道资源，另外电视机一定需要一个单独的接收模块来接收信号并进行处理。这样必然增加了硬件成本，而且接收模块受主机结构的影响增加了设计难度，难以统一和推广。
发明内容
本发明的目的在于提供一种结构简单、设计开发难度低的用电视红外接收头实现鼠标功能的方法。
本发明的另一目的在于提供一种结构简单、设计开发难度低的用电视红外接收头实现鼠标功能的系统。
为实现上述目的，本发明提供一种用电视红外接收头实现鼠标功能的方法。该方法通过带有触摸板模块的遥控器感应输入操作并将输入操作处理成鼠标编码以红外信号的方式发射出去，通过电视端的红外接收头接收遥控器发射的所述红外信号并对所述红外信号解码得到鼠标码值，将解码后的所述鼠标码值发送给电视主芯片，通过所述电视主芯片响应所述鼠标码值得到对应的鼠标功能。
优选地，在所述电视主芯片中设置底层驱动和应用层，所述通过电视主芯片响应所述鼠标码值得到对应的鼠标功能的操作为：通过底层驱动响应鼠标码值而生成相应鼠标事件并将该鼠标事件上报到应用层，以及通过应用层接收底层驱动上报的鼠标事件而得到相应的鼠标功能。
优选地，所述鼠标编码由头码、系统码和鼠标功能码组成，通过头码判别遥控器处于普通按键方式还是鼠标功能方式，通过系统码区分遥控器的类型，通过鼠标功能码区别出具体的鼠标功能。
优选地，将所述系统码长度设为4bit，将所述鼠标功能码长度设为24bit。
优选地，将鼠标编码的“0”用0.3ms高电平和0.6ms低电平表示，将鼠标编码的“1”用0.3ms高电平和0.3ms低电平表示。
优选地，将一个鼠标编码长设置为22.2ms~28.8ms。
为实现上述目的，本发明提供另一种用电视红外接收头实现鼠标功能的方法，包括如下步骤：步骤一、通过带有触摸板模块遥控器感应输入操作并将输入操作处理成鼠标编码以红外信号的方式发射出去；其中，所述鼠标编码包括用于判别遥控器处于普通按键模式还是鼠标功能模式的头码、用于供系统区分遥控器类型的系统码，以及用于区别出具体的鼠标功能的鼠标功能码；步骤二、通过电视端的红外接收头接收遥控器发射的所述红外信号并对所述红外信号解码得到鼠标码值；步骤三、将解码后的所述鼠标码值发送给电视主芯片；以及步骤四、通过所述电视芯片中的底层驱动响应鼠标码值而生成相应鼠标事件并将该鼠标事件上报到所述电视芯片中的应用层，以及通过应用层接收底层驱动上报的鼠标事件而得到相应的鼠标功能。
优选地，将所述系统码长度设为4bit，将所述鼠标功能码长度设为24bit。
优选地，将鼠标编码的“0”用0.3ms高电平和0.6ms低电平表示，将鼠标编码的“1”用0.3ms高电平和0.3ms低电平表示。
优选地，将一个鼠标编码长设置为22.2ms~28.8ms。
相应的，本发明提供了一种用电视红外接收头实现鼠标功能的系统，包括遥控器、红外接收头和电视主芯片。该遥控器具有触摸板模块、将触摸板模块感应的输入操作处理成鼠标编码的编码芯片模块以及发射含有鼠标编码的红外信号的红外发射电路模块，红外接收头接收遥控器发射的红外信号并对该红外信号解码得到鼠标码值，所述电视主芯片通过响应所述鼠标码值得到对应的鼠标功能。
作为进一步改进，所述电视主芯片具有底层驱动和应用层，所述电视主芯片通过响应所述鼠标码值得到对应的鼠标功能的操作包括：底层驱动响应所述鼠标码值并生成相应的鼠标事件，以及应用层接收驱动层上报的所述鼠标事件而得到相应的鼠标功能。

附图说明
图1 为本发明用电视红外接收头实现鼠标功能的系统的结构示意图；
图2 为本发明用电视红外接收头实现鼠标功能的方法的流程图。
具体实施方式
为了详细说明本发明的技术内容、所达成的目的及效果，下面将结合具体实施例并配合附图，对本发明的技术方案进行清楚、完整地描述。
请参阅图1，本发明用电视红外接收头实现鼠标功能的系统包括遥控器10、电视机的红外接收头20和电视主芯片30。
遥控器10作为发射端具有触摸板模块110、编码芯片模块120（含触摸感应处理功能和红外编码功能）以及红外发射电路模块130。
触摸板模块110作为输入接口有很多感应单元，这些感应单元以矩阵形式排列，定义水平方向为X轴，垂直方向为Y轴，每一列或一排的感应单元都连接到编码芯片模块120的输入口。当人的手指在触摸板模块110上移动时，就会改变这些矩阵感应单元的相关参数，因此，触摸板模块110可以感应输入操作并产生输入操作信号，触摸板模块110将其产生的输入操作信号输送给编码芯片模块120，编码芯片模块120通过其输入口接收触摸板模块110产生的输入操作信号并对该输入操作信号进行处理而生成鼠标编码。
鼠标编码是一套独立的编码方式，有别于普通的按键编码。普通按键编码有头码、4bit系统码、8bit（即1byte）按键码以及系统码和按键码的反码组成，0.5ms高电平和2ms低电平表示“0”，0.5ms高电平和1ms低电平表示“1”，一个按键码长约56ms。鼠标编码由头码、4bit系统码和24bit（即3byte）鼠标功能码组成，其中4bit系统码和按键编码相同，以便电视机区分不同类型的遥控器。头码和普通按键的不一样，主机通过头码即可判断是普通按键还是鼠标功能，24bit鼠标功能码通过设定其中特定的比特位来作为标志位，区别出具体的鼠标功能（单击、双击、鼠标滑动或滑条等），其它比特位则表示鼠标水平和垂直方向的移动量。鼠标编码的“0”用0.3ms高电平和0.6ms低电平表示，鼠标编码的“1”用0.3ms高电平和0.3ms低电平表示，一个鼠标编码长为22.2ms~28.8ms，这样一个鼠标码值相对较短，在单位时间内传送的鼠标编码的数量就比较多，鼠标的灵敏度就比较好。
电视机的红外接收头20基本上都是用红外一体化接收头，其接收到遥控器10发射的红外信号后经过放大、滤波和解码后得到鼠标码值，并通过电视主芯片30的红外通道直接送到电视主芯片30，因此，鼠标码值不需要再做任何信号转换即可通过红外通道发送到电视主芯片30。
电视主芯片30采用和遥控器10相同的编码规则对鼠标编码进行解码。电视主芯片30可根据鼠标编码要求能够处理鼠标和手势事件。电视主芯片30具有驱动层310和应用层320。驱动层310根据遥控器10的鼠标编码规则作为识别依据，对电视主芯片30的红外通道接收到红外接收头20发送过来的鼠标码值后对其识别和判断，然后转换成相应的鼠标事件，比如鼠标移动、鼠标单双击、屏幕滚动事件等。驱动层310产生的鼠标事件发送到应用层320，由应用层320来响应各个鼠标事件并最终实现鼠标功能，通过电视显示端即可看到各种鼠标操作结果。
请参阅图2，本发明用电视红外接收头实现鼠标功能的方法包括：
步骤一、通过带有触摸板模块的遥控器感应输入操作并将输入操作处理成鼠标编码以红外信号的方式发射出去；
步骤二、通过电视端的红外接收头接收遥控器发射的所述红外信号并对所述红外信号解码得到鼠标码值；
步骤三、通过红外接收头将解码后的所述鼠标码值发送给电视主芯片；以及
步骤四、通过所述电视主芯片响应所述鼠标码值得到对应的鼠标功能。
在本实施例中，步骤一的具体操作为：通过遥控器10的触摸板模块110感应人手的输入操作并产生输入操作信号，通过遥控器10的编码芯片模块120将触摸板模块110产生的输入操作信号编码而生成鼠标编码，以及通过遥控器10的红外发射电路模块130将编码芯片模块120生成鼠标编码以红外信号的方式发射出去。且步骤二中，通过电视端的红外接收头接收遥控器的红外发射电路模块130发射的红外信号。
在本实施例中，步骤四的具体操作为：通过电视主芯片30的底层驱动310响应鼠标码值而生成相应鼠标事件并将该鼠标事件上报到应用层320，以及通过电视主芯片的应用层320接收底层驱动310上报的鼠标事件而得到相应的鼠标功能。
由于本发明方法和系统中的遥控器10在传统按键遥控器基础上增加触摸板模块110，通过触摸板模块110感应人手操作，产生鼠标编码发射到电视端，电视主芯片30通过中断方式响应鼠标码值，这和普通遥控器的响应方式是一样的，不需要任何信号转换，因此电视端不增加任何硬件成本。
此外，该本发明方法中触摸板模块110产生的鼠标编码使用与遥控器10的普通按键不同的编码方式，这种鼠标编码和普通按键编码有相同的系统码，以便于电视机的正确识别，但是鼠标编码有更多的字节数，这样能实现诸如鼠标移动、鼠标单双击及手势功能等更多的鼠标功能，另外为了增加鼠标的灵敏度，该鼠标编码的0和1的码宽度也比普通按键编码的短。该方法使得电视不管在什么工作状态下都能实现流畅的移动鼠标操作。
以上实施例仅用以说明本发明实施例的技术方案，而非对其限制；尽管参照前述实施例对本发明实施例进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明实施例各实施例技术方案的精神和范围。
