其中，在车辆行驶过程中，通常在车辆的前方、后方位置会存在驾驶员无法看到的视角即盲区，因此为了消除盲区，流媒体采集器10可以为安装在车辆的前方或后方位置的摄像头，其可以实时拍摄车辆前方或后方位置外部环境的全景图像，外部环境的全景图像可以为静态画面或动态视频中的至少一个，即车辆外部环境流媒体信息可以包括车辆外部环境流媒体画面或动态视频等中的至少一个。
优选地，摄像头可以采用360度环视广角摄像头，用于对车辆的前方或后方进行全景扫描，以获取车辆的前方或后方的流媒体全景环视影像。
中央控制器11与中央显示器12相连，用于获取流媒体采集器10采集的车辆外部环境流媒体信息，将车辆外部环境流媒体信息转换为对应的流媒体画面后，控制中央显示器的显示屏显示流媒体画面。
中央控制器11还用于在定义显示尺寸画面接收定义显示尺寸操作（定义显示尺寸操作例如由用户点击定义显示尺寸按键或按钮，并进行显示尺寸的调整），则根据定义的显示尺寸，将车辆外部环境流媒体信息转换至定义显示尺寸的流媒体画面后，控制中央显示器的显示屏根据定义的显示尺寸显示流媒体画面。
其中，定义的显示尺寸可以包括设置流媒体画面的显示区域、设置全屏显示流媒体画面、恢复原始尺寸显示流媒体画面、设置流媒体画面显示在显示屏左侧或右侧、将流媒体画面进行分屏显示等中的至少一个。
中央控制器11可以在定义显示尺寸画面接收定义显示尺寸操作（例如点击定义显示尺寸按键或按钮等操作，并进行了显示尺寸的调整），则根据定义的显示尺寸，将车辆外部环境流媒体信息转换至定义显示尺寸的流媒体画面后，控制中央显示器12的显示屏根据定义的显示尺寸显示流媒体画面。
这样，用户可以自主定义显示流媒体画面的尺寸，进行显示区域调整。显示区域调整时可选择8个方向，对8个方向的显示范围进行自主定义尺寸，也可以设置一键全屏显示流媒体画面，还可以恢复原始尺寸（原始尺寸可以是预先设定的尺寸）显示流媒体画面，还可以设置流媒体画面显示在显示屏左侧或右侧，或将流媒体画面进行分屏显示，并且流媒体画面的显示方向和人体感方向一致，且流媒体画面内的文字标识等可正常阅读识别，以提高用户体验。
中央控制器11还用于在上电开启后，控制中央显示器12的显示屏显示尺寸设置说明画面，接收到退出尺寸设置说明画面操作（例如可以为点击尺寸设置说明画面操作），则退出尺寸设置说明画面，还可以直接控制显示屏显示定义显示尺寸画面，或者在接收到长按显示屏一段时间操作，则控制显示屏显示定义显示尺寸画面，再在定义显示尺寸画面接收定义显示尺寸操作，则根据定义的显示尺寸，将车辆外部环境流媒体信息转换至定义显示尺寸的流媒体画面后，控制中央显示器12的显示屏根据定义的显示尺寸显示流媒体画面。
其中，中央控制器11可以在每次上电开启后，可以控制显示器的显示屏显示尺寸设置说明，可以每次上电显示提示一次，一共可以显示提示多次，例如3次，用户点击尺寸设置说明画面，则尺寸设置画面消失，显示屏显示流媒体画面。或者若用户长按显示屏一段时间，例如3秒，则显示屏的画面进入显示定义显示尺寸状态。
中央控制器11还用于接收到拖动流媒体画面至目标位置操作时，控制流媒体画面移动到中央显示器12的显示屏的目标位置。这样，用户可随意拖动流媒体画面在中央显示器12的显示屏移动，这样流媒体画面在显示屏上可以保持正常显示而不会遮挡其他应用，避免影响其他功能使用。
中央控制器11还用于根据车辆外部环境流媒体信息得到车辆周围障碍物信息（包括障碍物位置、车辆与周围障碍物的距离等信息），控制中央显示器12的显示屏将车辆周围障碍物信息显示至流媒体画面。
其中，中央控制器11可以根据车辆外部环境流媒体信息得到车辆周围障碍物信息，例如障碍物位置、车辆与周围障碍物的距离等信息，控制显示屏的流媒体画面进行车辆周围障碍物可视化标记，并显示车辆与周围障碍物的距离。
这样，系统还拓展增加了目标物识别可视化功能，针对人、动物、移动的车辆等障碍物在流媒体画面上进行可视化标记，并在流媒体画面实时显示障碍物距离车辆的距离，以协助驾驶员进行安全驾驶。
中央显示器12可以在中央控制器11的控制下显示流媒体画面，这样流媒体画面集中显示在显示屏上，不需要单独采购内后视镜，降低了成本，而且能够快速、有效、便捷、实时地查看车辆周围路况，并且实用性强。
中央控制器11还用于接收到启动流媒体操作，则输出启动命令至中央显示器，以控制中央显示器的显示屏显示定义显示尺寸画面或流媒体画面，所述中央控制器接收到关闭流媒体操作，则输出关闭命令至中央显示器，以控制中央显示器的显示屏关闭流媒体画面。
其中，启动流媒体操作或关闭流媒体操作可以是用户点击显示在显示屏上的启动流媒体按键操作或关闭流媒体按键操作，方便前排乘客和驾驶员操作。
优选地，如图2所示，车载流媒体显示系统还可以包括与中央控制器11相连的语音采集模块（MIC）13。语音采集模块13用于采集语音。语音采集模块13可以为安装在靠近驾驶座位置处的麦克风等。
中央处理器11获取语音采集模块11采集的语音，并对语音进行识别，若识别出的语音是启动流媒体，则输出启动命令至中央显示器12，以控制中央显示器12的显示屏显示定义显示尺寸画面或流媒体画面，若识别出的语音是关闭流媒体，则输出关闭命令至中央显示器12，以控制中央显示器12的显示屏关闭流媒体画面。
这样，不仅可以操作在显示屏显示的启动或关闭按钮，还可以利用语音启动或关闭流媒体画面，使得驾驶员和乘客操作更便捷。
