Description
Technical Field
The invention relates to the technical field of network television image communication, in particular to a method for solving the problem of playing ghost when an HOME key in an IPTV exits.
Background
An IPTV (internet protocol television) is a new technology for providing a plurality of interactive services including digital televisions to home users by using a broadband cable television network and integrating a plurality of technologies such as internet, multimedia, and communication, and the IPTV service itself includes a computer, a television, a mobile phone, and a portable terminal, integrates broadcasting and communication technologies, collects multimedia integrated services of a cable and a wireless IP network, is an important representative of new media, and provides video and audio services on all IP networks, such as video podcasting, video sharing, video searching, P2P Streaming, a broadband portal, a network television station, TPS, mobile video, and a mobile television, which belong to the IPTV service category.
At present, the domestic IPTV service is mainly provided to users by wide operators (including mobile, telecom and Unicom) in the form of value-added services, the operators install network set-top boxes with IPTV applications for users who purchase the value-added services, and provide fixed accounts for the set-top boxes, and the users obtain the IPTV services by using the set-top boxes.
The set-top box is customized for operators by each large set-top box manufacturer, and because the application equipment, platform version and system function adopted by each set-top box manufacturer are greatly different, each set-top box has partial function and performance difference, and partial system players provided by the set-top box have the problem of playing image residual when responding to the exit of a HOME key of a remote controller.
Disclosure of Invention
The invention aims to provide a method for solving the problem of playing image retention when a HOME key exits in an IPTV, which solves the problem that a system player provided by an IPTV set-top box has playing image retention when the HOME key exits.
The technical scheme adopted by the invention for solving the technical problems is as follows: a solution for playing ghost when HOME key exits in IPTV comprises:
s1, the registration system broadcasts and monitors HOME keys;
s2, after monitoring the HOME key event, thoroughly releasing the player resource and resetting the state of the playing window;
s3, redrawing the canvas of the player after the playing window is reset, and setting the background of the playing window;
s4, changing the display state of the playing window to make the display state of the playing window view hidden before being displayed.
The invention has the following beneficial effects: the method is suitable for different set top box ROM systems, the watching effect of a user is effectively improved, and the product experience is improved.

Fig. 2 is a flowchart of the registration system broadcasting and monitoring HOME keys according to the present invention.
FIG. 3 is a flow chart of releasing a player when a HOME key event is monitored according to the present invention.
FIG. 4 is a flow diagram of resetting a canvas when a HOME key event is monitored according to the present invention.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
According to the solution shown in fig. 1 to fig. 4, a method for solving a ghost when a HOME key in an IPTV exits includes:
s1, the registration system broadcasts and monitors HOME keys;
s2, after monitoring the HOME key event, thoroughly releasing the player resource and resetting the state of the playing window;
s3, redrawing the canvas of the player after the playing window is reset, and setting the background of the playing window;
s4, changing the display state of the playing window to hide the display state of the playing window view and then display the hidden display state, so that the popup window is not displayed after the application exits, and the application can be played normally when the application enters again.
Specifically, the method for registering the system broadcast monitoring HOME key in step S1 is as follows:
s101, dynamically registering HOME key broadcast receivers, and responding to intention ACTION _ CLOSE _ SYSTEM _ DIALOGS of the android SYSTEM;
s102, judging the additional information of the intention in the HOME key broadcast receiver, confirming that the HOME key broadcast is based on the action name of the intention and the additional information, and filtering the event containing the homekey.
Specifically, the method for completely releasing the player resources in step S2 includes:
s201, the playing window executes a stopPlayBack () method to stop playing and release resources;
s202, starting a 200-millisecond delay task through an android handler;
s203, in the delay task, acquiring the current state of the playing window through reflection, and if the current state is not an idle state, executing a step S204;
s204, acquiring a MediaPlayer object of the playing window through reflection, and calling a release method of the MediaPlayer object;
s205, the MediaPlayer reference of the playing window is set to null by reflection.
Specifically, the method for redrawing the player canvas in step S3 includes:
s301, setting a canvas cleaning state for the playing window;
s302, rewriting a drawing method of the playing window, and drawing the canvas to be transparent when the cleaning state of the canvas is that the canvas needs to be cleaned;
s303, when the HOME key event is detected, setting the canvas cleaning state as the cleaning requirement, and triggering the drawing method of the rewritten playing window in the S302;
s304, monitoring a drawing method end event of the rewritten playing window, and if the canvas cleaning state is that cleaning is needed, binding Callback for the SurfaceHolder of the playing window again;
s305, setting the canvas cleaning state as not-required cleaning.
Specifically, the method for changing the display state of the play window in step S4 is as follows:
s401, calling a view display method of an android, and setting a play window to be in a display state;
s402, calling an android view hiding method, and setting the playing window to be in a hidden state.
The present invention is not limited to the above embodiments, and any structural changes made under the teaching of the present invention shall fall within the protection scope of the present invention, which is similar or similar to the technical solutions of the present invention.
