It please refers to Fig.2, which show the flow chart of another embodiment of television program playing method of the present invention.In the reality It applies in example, message queue is still set, moreover, message queue is preset with two states, it is as the permanent of first state respectively Wait state and the delay wait state as the second state.
As shown in Fig. 2, the process that the embodiment performs TV programme broadcasting is as follows:
Step 201:Flow starts.
Step 202:Setting message queue is permanent wait state.
In system initialization, the state of presetting message queue is permanent wait state.Under the permanent wait state, no Cyclic query is needed with the presence or absence of program play command, because without occupying the system resources such as CPU.
Step 203:The program play command of user is received, obtains the corresponding program play parameter of the program play command, And it is inserted into message queue.
When receiving the program play command that user is inputted by remote controler or television control panel, first obtain and program The corresponding program play parameter of play command, such as video PID, Audio PID are corresponding to be performed according to program play parameter The broadcasting of TV programme.Then, program play parameter is inserted into message queue.
Step 204:Determine whether to whether there is message in message queue.If in the presence of execution step 205;If being not present, after It is continuous to perform step 203.
There are during user's program play command, can generate with the corresponding message of the order, which, which is inserted into, disappears It ceases in queue.If there is message, illustrate that user has issued the order of program broadcasting.If there is no message, explanation is not present User will perform the order of program broadcasting, then perform step 203, continue to the program play command of user.Certainly, this field It will be appreciated by the skilled person that user's program play command mentioned here, for entering start-up picture after start, not performing some It is that user plays some appointed program by what remote controler or television control panel were sent for the television system that program plays Order, and for directly played according to memory function after start last time shutdown when program television system for, then refer to use The zapping order that family is sent by remote controler or television control panel.
Step 205:There are during message, judge whether message queue is permanent wait state.If so, perform step 206; If it is not, go to step 207.
Step 206:It is in permanent wait state and message queue there are during new message in message queue, broadcasts immediately The corresponding TV programme of effective program play parameter in message queue are put, the program play parameter is then arranged to invalid; Meanwhile message queue enters delay wait state, timer starts timing.Then, step 208 is gone to.
When message queue receives new message under permanent wait state, the program corresponding to message in message queue Play parameter is actual parameter, is the program play command of quick response user, then plays the effective program immediately and play ginseng The corresponding TV programme of number, it is ensured that first time zapping(Or program plays)Key commands are timely responded to.Moreover, it performs every time After complete program plays, the program play parameter corresponding to the program of the broadcasting is arranged to invalid, avoids accounting for message queue With and generate program play malfunction.
In addition, it is contemplated that user is when performing continuous zapping operation, it is desirable to see program pictures, entire zapping process as early as possible Will smooth not interim card, play back intermediate channel is as much as possible, to meet the these requirements of user, the embodiment is disappears It ceases queue and is 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.Permanently 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 be 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 It occupies, while is 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, it 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 has 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 intermediate 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 intermediate 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 It releases.
After the last one 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, which sets permanently 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 for the first time 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 partial programme broadcasting, the fluency to ensure continuous zapping, and can ensure the last one program that user sends The corresponding program of play command is come out by normal play, meets the viewing demand of user.Moreover, entire playback process process occupies The system resources such as CPU are less, improve the utilization rate of system resource.
