For example, in one mode, a dedicated control button on a control terminal such as a remote controller may be used to initiate a review process in the playback application, and then select a target program to be viewed back. The selection of the return program can also be implemented by another way of controlling the menu. After the control terminal receives the lookback request, the status identifier is set to look back, and then the playback process is restarted, and the current live broadcast interface control is reused, thereby switching from the live broadcast interface of the live broadcast program to returning to the target program. Look back at the interface. Conversely, switching from the look back interface to the live interface can also be achieved. In a specific embodiment, the following program statements can be used to implement the setting of the status identifier:
public final int STATE_LIVE＝0；Public final int STATE_LIVE=0;
public final int STATE_PLAYBACK＝1；Public final int STATE_PLAYBACK=1;
protected int mPlayState＝STATE_LIVE；Protected int mPlayState=STATE_LIVE;
......
public void setPlayState(int playState){Public void setPlayState(int playState){
    mPlayState＝playState；mPlayState=playState;
}}
在本申请的一个实施例中，根据要回看的目标节目的信息，获取所述目标节目的播放地址。所述目标节目的信息包括，但不限于，所述目标节目的名称、播放时间、播放频道等。而获取所述目标节目的播放地址的方式可以有很多种，例如，在当前的 播放地址后拼接时移信息生成新的播放地址，所述时移信息用于表示所述起始节目在当前频道的开始播放时间点到当前时间点之间的时间差。例如，用户选择需要回看的目标节目本来是在8:30分播放，当前时刻己经是10:00，因此，计算出的时间差就是90分钟，因此，就可以将该时间差信息拼接到当前频道对应的播放地址之后。然后就可以将新得到的地址发送到服务器，重新向服务器发送播放请求，服务器接收到新的地址之后，解析出地址中包含目标节目内容数据，以便在播放应用的客户端进行播放。In an embodiment of the present application, the play address of the target program is acquired according to the information of the target program to be viewed. The information of the target program includes, but is not limited to, a name of the target program, a play time, a play channel, and the like. There are many ways to obtain the play address of the target program, for example, at the current After the address is played, the stitching time shift information generates a new play address, and the time shift information is used to indicate the time difference between the start time of the current channel and the current time point of the current program. For example, the user selects the target program that needs to be viewed back to play at 8:30, and the current time is already 10:00. Therefore, the calculated time difference is 90 minutes, so the time difference information can be stitched to the current channel. After the corresponding play address. Then, the newly obtained address can be sent to the server, and the playback request is sent to the server again. After receiving the new address, the server parses out the address content data of the target program for playing in the client of the playback application.
在此的所述的“拼接”是一种更通俗的说法，实际上“拼接”可以是字符串链接，其例如可以通过如下程序语句实现：The term "splicing" as used herein is a more general term. In fact, "splicing" can be a string link, which can be implemented, for example, by the following program statement:
mUri＝Uri.parse(mCdeManager.getPlayUrl(mPlayArgs.uri.toString()+"&timeshift＝"+mPlayArgs.shift,mPlayArgs.station))；mUri=Uri.parse(mCdeManager.getPlayUrl(mPlayArgs.uri.toString()+"&timeshift="+mPlayArgs.shift,mPlayArgs.station));
这段代码中的“mPlayArgs.uri.toString()+"&timeshift＝"+mPlayArgs.shift”就是一个字符串链接。Java语言支持多个字符串通过‘+’字符链接成一个字符串。在这只是以Java语言举例，当然还可以采用其它编程语言来实现。The "mPlayArgs.uri.toString()+"&timeshift="+mPlayArgs.shift" in this code is a string link. The Java language supports multiple strings linked into a single string via the ‘+’ character. This is just an example of the Java language, and of course it can be implemented in other programming languages.
在本申请的一个实施例中，根据上述解析出的目标节目内容数据，启动用于播放所述目标节目的播放器。所述用于播放所述目标节目的播放器是对当前直播界面的继承。也就是，回看界面(replayView)是直播界面(liveView)的子类，用回看界面的对象代替直播界面的对象，通过状态机实现直播界面与回看界面的相互切换，从而实现了直播界面的复用，加快了用户观看界面的切换，减少了资源消耗。“继承”(extends)是Java语言的一个关键字，A extends B表示A继承B，也就是A称为父类，B称为子类。子类可以使用父类的公有方法和变量。例如，public class PlaybackView extends LiveTvView{...}。具体为，当用户选择回看目标节目时，通过状态控制将观看界面切换到回看界面，隐藏当前直播节目时特有的用户界面部分，保留与回看目标节目共有的用户界面部分，同时显示回看界面独有的用户界面部分。当用户选择回看目标节目时，通过状态控制将观看界面切换到直播界面，隐藏回看界面特有的用户界面部分，保留与直播界面共有的用户界面部分，同时显示直播界面独有的用户界面部分，实现了直播界面与回看界面中同样内容的共用，减小了内存损耗，提高了响应时间。In one embodiment of the present application, a player for playing the target program is activated based on the parsed target program content data. The player for playing the target program is an inheritance to the current live broadcast interface. That is to say, the lookback interface (replayView) is a subclass of the live interface (liveView), and replaces the object of the live interface with the object of the back interface, and realizes the mutual switching between the live interface and the look back interface through the state machine, thereby realizing the live broadcast interface. The reuse speeds up the switching of the user viewing interface and reduces resource consumption. "extends" is a keyword in the Java language, A extends B means that A inherits B, that is, A is called a parent class, and B is called a child class. Subclasses can use the public methods and variables of the parent class. For example, public class PlaybackView extends LiveTvView{...}. Specifically, when the user selects to look back at the target program, the viewing interface is switched to the look back interface through the state control, the user interface portion unique to the current live program is hidden, and the user interface portion shared with the back view target program is retained, and displayed at the same time. Look at the user interface section that is unique to the interface. When the user chooses to look back at the target program, the viewing interface is switched to the live interface through state control, the user interface portion unique to the interface is hidden, the user interface portion shared with the live interface is retained, and the user interface portion unique to the live interface is displayed. The sharing of the same content in the live interface and the look back interface is achieved, which reduces memory loss and improves response time.
