Description

处理装置、显示装置以及多媒体系统
本申请要求在2015年12月15日提交中国专利局、申请号为201510952132.9、发明名称为“处理装置、显示装置以及多媒体系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通信控制技术领域，更具体地，涉及一种基于近场通用串行总线(USB，Universal Serial Bus)无线传输的处理装置、显示装置以及多媒体系统。
背景技术
现有智能视频设备，如智能电视，处理器和显示器都是一体的。对于搭载操作系统的智能视频设备，在线软件升级已经普遍应用。例如，几年前使用安卓2.0的系统，目前，已经升级到5.0或更高。软件系统升级和硬件系统是密切相关的，当初满足安卓2.0的硬件系统，对于安卓5.0已经不适合。然而，现有的智能电视要进行硬件升级操作十分复杂，需要把一体的智能电视拆开，置换掉旧的处理器等元器件。需要专业的厂家来完成。
发明内容
本发明实施例的一个目的是提供一种分体式多媒体系统的新技术方案。
根据本发明实施例的第一方面，提供了一种处理装置，该处理装置包括：
与第一信号源通信连接的处理器，将所述第一信号源发出的控制命令转换为USB格式控制命令，再将所述USB格式控制命令发送；以及
与所述处理器通信连接的第一无线USB模块，接收所述USB格式控制命令并进行发送。
可选地，所述第一信号源发出的控制命令为I2C/GPIO格式控制命令。
可选地，所述处理器接收来自第二信号源的音/视频信号，再将所述音/视频信号转换为USB格式音/视频信号，并发送；
所述第一无线USB模块接收所述USB格式音/视频信号，并发送。
根据本发明的另一方面，提供了一种显示装置，该显示装置包括：
第二无线USB模块，接收所述USB格式控制命令并进行发送，
与所述第二无线USB模块通信连接的集线器，接收所述USB格式控制命令并通过第二端口进行发送；
与所述第二端口通信连接的第二转换器，接收所述USB格式控制命令并转换为I2C/GPIO格式控制命令再进行发送；以及
与所述第二转换器信号连接的多媒体播放器，接收所述I2C/GPIO格式控制命令并执行。
可选地，所述第二无线USB模块接收USB格式音/视频信号，并发送；
所述集线器接收所述USB格式音/视频信号并通过第一端口发送。
可选地，所述第一端口与第一转换器的接收端通信连接，所述第一转换器的发送端与第三转换器的接收端通信连接，所述第三转换器的发送端与多媒体播放器通信连接。
可选地，所述第一转换器为USB转HDMI转换器；所述第三转换器为HDMI转V_By_One格式转换桥片。
根据本发明实施例的又一方面，提供了一种多媒体系统，所述多媒体系统包括：本发明提供的所述的处理装置和本发明提供的所述的显示装置，所述处理装置与所述显示装置通过所述第一无线USB模块和所述第二无线USB模块通信连接。
可选地，所述处理装置与所述显示装置电性连接。
可选地，所述电性连接的方式为接触吸附式电性连接。
本发明实施例提供的处理装置结构简单，可以将控制命令转换为USB格式控制命令；然后，通过所述第一无线USB模块将USB格式控制命令进行发送。本发明提供的显示装置结构简单，可以通过所述第二无线USB模块接收USB格式控制命令，然后转换为I2C/GPIO格式控制命令，再进行执行，实现对多媒体播放器的控制。本发明提供的多媒体系统采用分体式设计，结构简单，通过所述第一无线USB模块和所述第二无线USB模块实现控制命令的传输，连接十分方便，需要对硬件进行升级时，只需更换处理装置或者显示装置即可，而无需对多媒体系统内部进行拆装，升级十分便捷。
