Will smooth not interim card, play back middle channel is as much as possible, to meet the these requirements of user, the embodiment is disappears
Cease queue and be provided with the second state that delay waits.Moreover, new message is received under permanent wait state, is played immediately
After corresponding TV programme, control message queue enters delay wait state, and timer starts timing.Forever wait and prolong
When wait both states, can be characterized by different variate-values and assignment.And it is delayed and waits corresponding delay time
For a default setting time, the timing time of timer is also the setting time.This setting time is broadcast for program twice
The maximum time interval put, can specifically set according to the requirement of system performance, user to program broadcasting speed, for example,
It may be set to 1000ms.
Step 207：If it is not permanent wait state to judge message queue in step 205, message queue is delay
Wait state.
As described above, the judgement of message queue state can be carried out by default state variable value.In the embodiment
In, message queue only has two states, if not permanent wait state, then in delay wait state.
When message queue is in delay wait state, if receiving new program play command, still by new program
The corresponding program play parameter of play command is inserted into message queue, but is not responding to the play operation of the program.Moreover, disappearing
During the delay wait state for ceasing queue, program play parameter that is old, not responding is covered with new program play parameter.
Step 208：Judge whether delay time has arrived.If do not arrived, continue to wait in delay；If having timed out, perform
Step 209.
Step 209：When delay time reaches, judge whether there is new effective program play parameter in message queue.If
Have, perform step 210；Otherwise, step 202 is gone to.
When judging that delay time reaches using timer, judge whether there is new effective program to play ginseng in message queue
Number.If not provided, explanation user in delay time does not send new program play command.In this case, to reduce resource
Take, while be the program play command of quick response next time, go to step 202, the state of message queue is arranged to again
Permanent wait state, the control process process that program plays since permanent wait state again.
Step 210：When delay time reaches and has new effective program play parameter in message queue, message is played
The corresponding TV programme of effective program play parameter finally received in queue, are then arranged to nothing by the program play parameter
Effect.Then, step 202 is gone to.
As described in step 206, new effective program play parameter is received under the permanent wait state of message queue, will
The broadcasting of the program is immediately performed, the program play parameter is then arranged to invalid, while control message queue enters delay
Wait state.During the wait state that is delayed, if receiving effective program play parameter again, illustrate in the delay of setting
Interior user have issued the program play command of zapping again.What it is due to delay time characterization is between the maximum time of zapping twice
Every, so, when delay time reaches, only play the corresponding electricity of effective program play parameter finally received in message queue
Depending on program.If centre also there are other program play command, show user's execution is continuous zapping operation, every to avoid
A platform respond and caused by it is not smooth, the corresponding program filtering of these middle program play command is fallen, is no longer played.If
User is not continuous zapping, and is only that a zapping operation is performed in delay time, can also ensure that the program is normally broadcast
Release.
After last program play command has been performed, which is arranged to invalid, then, is gone to
Step 202, the state of message queue is arranged to permanent wait state again, the program broadcasting since permanent wait state again
Control process process.
The embodiment sets forever to wait and be delayed for message queue waits the two states, and combines holding for program broadcasting
The queue of row control message constantly converts between the two states, both can guarantee that being immediately performed the program that user sends first plays
The broadcasting of the corresponding program of order, improves program and plays response speed, and can ensure that the continuous zapping process in speed
In omit the broadcasting of partial programme, to ensure the fluency of continuous zapping, and can ensure last program that user sends
The corresponding program of play command is come out by normal play, meets the viewing demand of user.Moreover, whole playback process process takes
