本发明涉及一种音视频技术， 尤其是一种音视频信号处理设备、 播放设 备、 系统及方法 （包括音视频信号处理方法、 音视频信号播放方法、 音视频 系统实现方法） 。  The invention relates to an audio and video technology, in particular to an audio and video signal processing device, a playing device, a system and a method (including an audio and video signal processing method, an audio and video signal playing method, and an audio and video system implementation method).
背景技术 Background technique
公知的， 电视机都离不开外接信号电缆线， 所以电视信号线在那， 电视 机就得摆到那， 反之， 得把电视信号线延伸到电视机旁边， 使用极不便利； 且一根信号电缆线只能连接单台电视机， 所以对于多房间多电视的情景， 重 复投资信源设备是一件不可避免的事情； 电视机从阴极射线管 （Cathode Ray Tube, 简称 CRT ) 电视发展到了液晶电视， 其作用已不仅仅是看电视节目， 还成了家庭装饰中不可分割的一部分， 虽然电视生产商生产的液晶电视机都 具备了挂墙安装功能， 但挂墙之后， 如何方便地处理好诸多难看的信号电缆 线的连接和布局是一个长期未解的难题。  It is well known that TV sets are inseparable from external signal cable, so the TV signal line is there, the TV set has to be placed there. On the contrary, it is necessary to extend the TV signal line to the TV set. It is extremely inconvenient to use; The signal cable can only be connected to a single TV set. Therefore, for multi-room and multi-TV scenarios, it is inevitable to re-invest in the source device. The TV has evolved from cathode ray tube (CRT) TV to LCD TV, its role has not only watched TV programs, but also became an inseparable part of home decoration. Although LCD TVs produced by TV manufacturers have wall-mounted installation functions, how to handle them easily after wall-hanging The connection and layout of many ugly signal cables is a long-standing unsolved problem.
有线电视机顶盒（ SetBox ) 、 交互式网络电视（ IPTV )机顶盒或其他视 频机顶盒（BOX )都需要电视机作为显示终端， 不仅仍然是需要在他们之间 连接信号电缆， 而且还增加了一个额外的遥控器， 使得电视机的使用变得更 加复杂繁瑣；  Cable set-top boxes (SetBox), interactive network television (IPTV) set-top boxes or other video set-top boxes (BOX) require a TV as a display terminal, not only the signal cable needs to be connected between them, but also an additional remote control. , making the use of the TV more complicated and cumbersome;
因为电视机的摆放位置受到信号线的约束， 如果房屋装修， 或者重新布 局， 就需要重新布置信号线， 为住户带来不便。  Because the position of the TV set is constrained by the signal line, if the house is renovated or re-arranged, the signal line needs to be rearranged to bring inconvenience to the residents.
电视机作为家庭必备的消费品， 已经开始走向智能化。 然而消费者想要 享受技术更新带来的愉悦， 就得完全更换电视机； 例如随着技术进步， 越来 越多的新功能成为家庭电视机的一部分， 例如运行智能操作系统， 集成上网 功能， 游戏娱乐中心等等。 但在现有电视架构下， 这些新的功能被集成在新 型电视中。 用户要享受到这些新的功能， 必须要更换新的电视机。 但是， 考 虑这些功能和显示屏幕是无关的， 而且显示屏的寿命长达 7年之久。 用户为 了获得新的功能而频繁的更换电视机， 是非常不经济的。 发明内容 As a must-have consumer product for the family, TV sets have begun to become intelligent. However, consumers want to enjoy the joy of technology updates, they have to completely replace the TV; for example, as technology advances, more and more new features become part of the home TV, such as running a smart operating system, integrated Internet access, Game entertainment center and more. But under the existing TV architecture, these new features are integrated into the new TV. To enjoy these new features, users must replace them with new ones. However, considering these features is irrelevant to the display screen, and the display has a long life span of 7 years. User is It is very uneconomical to change the TV set frequently to obtain new functions. Summary of the invention
