具体实施方式detailed description
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
本发明提供一种视频播放控制方法。参照图1，图1为本发明视频播放控制方法第一实施例的流程示意图。The invention provides a video playback control method. 1 is a schematic flowchart of a first embodiment of a video playback control method according to the present invention.
在本实施例中，该视频播放控制方法包括：In this embodiment, the video playback control method includes:
步骤S10，在侦测到视频切换指令时，获取所述视频切换指令对应的待切换多媒体应用；Step S10: Acquire a multimedia application to be switched corresponding to the video switching instruction when detecting a video switching instruction;
其中，多媒体应用包括天籁K歌、爱奇艺视频、优酷视频等视频、音乐应用以及HDMI (High Definition Multimedia Interface，高清晰度多媒体接口)应用、DTV应用等。视频切换指令是指用户在需要切换多媒体应用时通过遥控器等终端或者智能电视的面板等发送的指令，在接收到用户通过遥控器等终端或者电视的面板发送或输入的视频切换指令时，智能电视获取该视频切换指令对应的待切换多媒体应用，其中，该待切换多媒体应用可以为智能电视中除当前多媒体应用之外的任一多媒体应用。Among them, multimedia applications include Tianzhu K song, iQiyi video, Youku video and other video, music applications and HDMI (High Definition Multimedia Interface, high-definition multimedia interface) applications, DTV applications, etc. The video switching instruction refers to a command sent by a user through a terminal such as a remote controller or a panel of a smart TV when a multimedia application needs to be switched, and is intelligent when receiving a video switching instruction sent or input by a user through a terminal such as a remote controller or a panel of a television. The television acquires the multimedia application to be switched corresponding to the video switching instruction, where the multimedia application to be switched may be any multimedia application other than the current multimedia application in the smart television.
步骤S20，在终端的显示界面显示有视频节目时，获取所述待切换多媒体应用以及显示界面显示的视频节目对应的当前多媒体应用之间的第一切换时长，其中，所述第一切换时长大于当前多媒体应用的关闭时长；In step S20, when the video program is displayed on the display interface of the terminal, the first switching duration between the multimedia application to be switched and the current multimedia application corresponding to the video program displayed on the display interface is obtained, where the first switching duration is greater than The closing time of the current multimedia application;
其中，第一切换时长是指待切换多媒体应用与当前多媒体应用进行切换时电视系统所需要消耗的时间。在当前多媒体应用与待切换多媒体应用是第一次视频切换时，第一切换时长包括当前多媒体应用的关闭时长（内存释放时长）以及待切换多媒体应用的启动时长，而多媒体应用的内存释放时长以及启动时长由该多媒体应用的内存大小决定，因此，智能电视等终端的不同多媒体应用之间的切换时长主要由待切换多媒体应用及当前多媒体应用的内存大小决定。本实施例中，通过分别获取待切换多媒体应用与当前多媒体应用的内存大小，然后根据获取到的待切换多媒体应用与当前多媒体应用的内存大小分别计算待切换多媒体应用的启动时长与当前多媒体应用的关闭时长，再将计算得到的待切换多媒体应用的启动时长与当前多媒体应用的关闭时长相加即可得到待切换多媒体应用与当前多媒体应用之间的第一切换时长，例如，当前多媒体应用优酷视频所占用的内存大小为1000M，则当前多媒体应用的关闭时长为1000ms，待切换多媒体应用DTV多媒体应用的内存大小为1100M，则待切换多媒体应用的启动时长为1100ms，因此，该待切换多媒体应用与当前多媒体应用之间的第一切换时长为2100ms，其中，多媒体应用的内存大小每增加100M则其对应的切换时长增加100ms。当然，在当前多媒体应用与待切换多媒体应用不是第一次视频切换时，可以获取智能电视系统存储的当前多媒体应用与待切换多媒体应用的第一切换时长，该第一切换时长为当前多媒体应用与待切换多媒体应用的前一次切换的切换时长，其中前一次的多媒体应用切换可以为由当前多媒体应用切换至待切换多媒体应用或者由待切换多媒体应用切换至当前多媒体应用，本实施例中，在获取到第一切换时长时，关联存储待切换多媒体应用、当前多媒体应用以及第一切换时长。The first switching duration refers to the time required by the television system when the multimedia application to be switched is switched with the current multimedia application. When the current multimedia application and the multimedia application to be switched are the first video switching, the first switching duration includes the closing duration of the current multimedia application (the memory release duration) and the startup duration of the multimedia application to be switched, and the memory release duration of the multimedia application and The startup time is determined by the memory size of the multimedia application. Therefore, the switching duration between different multimedia applications of the terminal such as the smart TV is mainly determined by the memory size of the multimedia application to be switched and the current multimedia application. In this embodiment, the memory size of the multimedia application to be switched and the current multimedia application are respectively obtained, and then the startup time of the multimedia application to be switched and the current multimedia application are respectively calculated according to the acquired memory size of the multimedia application to be switched and the current multimedia application. After the duration of the multimedia application is changed, the start time of the multimedia application to be switched is added to the current multimedia application to obtain the first switching duration between the multimedia application to be switched and the current multimedia application, for example, the current multimedia application Youku video The memory usage is 1000M, and the current multimedia application is closed for 1000ms. The memory size of the DTV multimedia application to be switched is 1100M, and the startup time of the multimedia application to be switched is 1100ms. Therefore, the multimedia application to be switched is The first switching duration between the current multimedia applications is 2100 ms, wherein the corresponding switching duration is increased by 100 ms for each 100M increase in the memory size of the multimedia application. Certainly, when the current multimedia application and the multimedia application to be switched are not the first video switching, the first switching duration of the current multimedia application and the multimedia application to be switched stored by the smart television system may be obtained, where the first switching duration is the current multimedia application and The switching duration of the previous handover of the multimedia application to be switched, wherein the previous multimedia application handover may be switched from the current multimedia application to the multimedia application to be switched or the multimedia application to be switched to the current multimedia application. In this embodiment, the acquisition is performed.
