现有技术中智能视频系统方案处理器的主板和显示系统一般是组装成一体，如果想对系统硬件升级需要拆装外壳才能取出内部主板进行更换，操作复杂，升级成本较高。而单纯的更换整机成本又比较昂贵。
分体电视作为智能电视产品新的形态已逐渐被电视研发厂商采用，其特点是视频主系统与显示系统部分分离，对主系统升级不需更换显示系统部分，减少系统升级成本，升级便利。分体电视需要对两个独立部分分别供电；即对独立的主系统部分供电，同时对独立的显示系统供电。
图1是现有技术中分体电视供电方案结构示意图，如图1所示，现有技术中分体电视的供电方案通常是，将电源板集成在显示系统端，再从位于显示系统的电源板引出直流电源线对主系统进行供电。现有技术中，使用一块交流输入电源板对显示系统和主系统供电，以达到节能目的。但在实现本申请过程中，发明人发现现有技术中至少存在如下问题：现有技术中如果需要单独使用主系统时，需要提供额外的电源适配器对主系统进行供电，增加客户的成本，从而导致用户体验不佳，而降低其对于使用音视频播放设备的意愿。
发明内容
本申请实施例提供一种音视频播放装置及其供电方法，能够使音视频播放设备的主处理器部分在独立于显示系统工作时，可以无需电源适配器而直接使用。
本申请实施例提供一种音视频播放装置，包括：

本申请实施例提供一种音视频播放装置的供电方法，包括：
第一电源模块输出的直流电经过开关控制器电路控制第二电源模块的打开与关闭，第一电源模块为主处理器系统供电，第二电源模块为显示系统供电。
本申请实施例提供的音视频播放装置及其供电方法对分体电视的主处理器系统和显示系统分别独立供电，从而可以在无需电源适配器的情况下单独使用分体电视的主处理系统，可以增加分体电视主处理系统的利用率。
