Description
本申请要求于2015年07月15日提交中国专利局,申请号为201510417470.2、发明名称为“投影数据的处理方法、处理装置、终端和投影系统”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。
本发明涉及投影技术领域,具体而言,涉及一种投影数据的处理方法、一种投影数据的处理装置、一种终端以及一种投影系统。
在相关技术中,投影设备对待投影数据进行投影时,首先通过与投影设备相连的终端对待投影数据进行解码,以将待投影数据转化成对应的投影信息并发送至投影设备,投影设备根据来自终端的投影信号对待投影数据进行投影。另外,也可以通过投影设备直接对待投影数据进行解码以对待投影数据进行投影。
但是,相关技术中的投影方案只是单一的利用终端或者投影设备对待投影数据进行解码,而未充分考虑终端和投影设备的解码能力等,例如,在投影设备对待投影数据进行解码时,但是投影设备的解码能力较低,而终端的解码能力比较高,这样就导致了不能充分利用终端的较强的解码能力,同时通过具有较低的解码能力的投影设备进行解码也降低了解码效率,也就导致了对待投影数据进行投影的不流畅。
因此,如何提高对待投影数据的解码效率,以及提高待投影数据在投影时的流畅性成为亟待解决的问题。
