Description
The application is a divisional application of a Chinese patent application 201310396568.5 entitled "television program playing method and playing device" provided in 09/04 in 2013.
Technical Field
The invention relates to a digital television processing technology, in particular to a television program playing method and a playing device.
Background
Television program playing is the most basic function of television playing terminals such as a digital television set-top box, a digital television all-in-one machine and the like, and television program channel changing by a user through a remote controller or control panel keys is also the most basic user operation. When an existing television playing terminal executes television program playing, a common processing method is as follows: in a thread (or called task), an unconditional loop is used to inquire whether a program playing command exists, and if so, the program playing is executed. In order to prevent the problem that the operating experience of a user is affected due to the fact that a CPU is seriously occupied because the program is continuously played under the condition of continuous channel changing, a fixed Sleep delay is added in an unconditional cycle, and the program playing is executed when the delay time is up.
However, the television program playing method has the following disadvantages:
(1) the program playing operation of the user cannot be responded to quickly. For example, when the user presses the zapping key, it is possible that the unconditional loop in the thread is in a Sleep delay state, and the query and the program playing can be started only after the Sleep is finished.
(2) Wasting system resources such as CPU. Unconditional circulation in the thread is always operated, even if the CPU is released through Sleep delay in the middle, because the channel changing time of a user is very little in the operation process of the whole television playing terminal, a large amount of system resources such as the CPU and the like are still occupied in the non-delay process.
Disclosure of Invention
The invention aims to provide a television program playing method and a television program playing device, which realize the playing of television programs by utilizing a message queue, thereby reducing the occupation of system resources such as a CPU (central processing unit) and the like by the playing of the television programs.
In order to achieve the above purpose, the television program playing method provided by the invention is realized by adopting the following technical scheme:
a method for playing back a television program, said method comprising the steps of:
a. presetting a message queue for storing program playing parameters;
b. when a program playing command of a user is received, acquiring a program playing parameter corresponding to the program playing command, and inserting the program playing parameter into the message queue;
c. and immediately or delaying to play the television program corresponding to the effective program playing parameter in the message queue according to the state of the message queue.
In the playing method, the message queue is preset with a first state, where the first state is an initialization state of the message queue and a state where there is no valid program playing parameter in the message queue within a set time, and in step c, if the message queue is in the first state, the television program corresponding to the valid program playing parameter in the message queue is immediately played.
In the above playing method, in order to increase the playing speed of the program during the continuous channel change, the message queue is preset with a second state, where the second state is a state entered by the message queue receiving a new effective program playing parameter in the first state, and in the step c, if the message queue is in the second state, the television program corresponding to the effective program playing parameter in the message queue is played in a delayed manner.
In the above playing method, in order to ensure that the last program is played normally, in the step c, if the message queue is in the second state, after the set time is reached, the television program corresponding to the last received effective program playing parameter in the message queue is played.
Wherein the set time is counted from a time when the message queue enters the second state.
In the above playing method, to further reduce the occupation of system resources by program playing, when the message queue is in the second state, if no new valid program playing parameter is received between the settings, or after the television program corresponding to the last received valid program playing parameter is played, the second state is exited, and the first state is entered.
In the above playing method, after the execution of the television program corresponding to the valid program playing parameter is completed, the program playing parameter corresponding to the television program is set to be invalid.
In order to achieve the above object, the television program playing device provided by the present invention is implemented by adopting the following technical scheme:

Detailed Description
The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a flowchart of a television program playing method according to an embodiment of the present invention is shown.
As shown in fig. 1, the process of playing a television program according to this embodiment is as follows:
step 101: the process begins.
Step 102: and presetting a message queue.
In order to implement the message mode for playing the television program, the embodiment is preset with a message queue for storing the program playing parameters.
Step 103: and receiving a program playing command of a user, acquiring a program playing parameter corresponding to the program playing command, and inserting the program playing parameter into the message queue.
When a program playing command input by a user through a remote controller or a television control panel is received, program playing parameters such as video PID, audio PID and the like corresponding to the program playing command are firstly acquired so as to execute playing of a corresponding television program according to the program playing parameters. The program play parameters are then inserted into the message queue.
Step 104: and immediately or delaying to play the television program corresponding to the effective program playing parameter in the message queue according to the state of the message queue.
When the effective program playing parameters exist in the message queue, the corresponding television program can be played by directly using the program playing parameters.
By setting the message queue, the program playing parameters related to the program playing command can be stored, and the television program playing command is reflected in a semaphore manner of a message. In addition, the message queue also has the functions of temporary storage and delayed processing, so that different states can be set for the message queue, and the television program can be played immediately or delayed according to the different states, so as to meet the requirement of the user on the program playing processing during continuous channel switching. The embodiment of fig. 2 may be referred to according to a specific implementation method of the instant or delayed message queue status processing.
Referring to fig. 2, a flow chart of a television program playing method according to another embodiment of the present invention is shown. In this embodiment, the message queue is still set, and the message queue is preset with two states, namely a permanent waiting state as the first state and a delayed waiting state as the second state.
As shown in fig. 2, the process of playing the tv program in this embodiment is as follows:
step 201: the process begins.
Step 202: the message queue is set to a permanent wait state.
When the system is initialized, the state of the message queue is preset to be a permanent waiting state. In the permanent waiting state, it is not necessary to circularly inquire whether a program playing command exists, so that system resources such as a CPU (central processing unit) and the like are not occupied.
Step 203: and receiving a program playing command of a user, acquiring a program playing parameter corresponding to the program playing command, and inserting the program playing parameter into the message queue.
When a program playing command input by a user through a remote controller or a television control panel is received, program playing parameters such as video PID, audio PID and the like corresponding to the program playing command are firstly acquired so as to execute playing of a corresponding television program according to the program playing parameters. The program play parameters are then inserted into the message queue.
Step 204: it is determined whether a message exists in the message queue. If yes, go to step 205; if not, go to step 203.
When a user program play command is present, a message corresponding to the command is generated and inserted into the message queue. If the message exists, the user is instructed to play the program. If there is no message indicating that there is no command for the user to execute the program playing, step 203 is executed to continue receiving the program playing command of the user. Of course, it should be understood by those skilled in the art that the user program playing command mentioned herein refers to a command for playing a specific program sent by the user through a remote controller or a television control panel for a television system that enters a startup picture after startup and does not execute a certain program playing, and refers to a channel change command sent by the user through the remote controller or the television control panel for a television system that directly plays a program when the television system is powered off last time according to a memory function after startup.
Step 205: and when the message exists, judging whether the message queue is in a permanent waiting state. If yes, go to step 206; if not, go to step 207.
Step 206: when the message queue is in a permanent waiting state and new messages exist in the message queue, immediately playing the television program corresponding to the effective program playing parameters in the message queue, and then setting the program playing parameters to be invalid; meanwhile, the message queue enters a delay waiting state, and the timer starts to time. Then, go to step 208.
When the message queue receives a new message in a permanent waiting state, the program playing parameter corresponding to the message in the message queue is an effective parameter, and if the program playing parameter is a program playing command of a quick response user, the television program corresponding to the effective program playing parameter is immediately played, so that the first channel change (or program playing) key command is ensured to be responded in time. And after the program playing is executed each time, the program playing parameter corresponding to the played program is set to be invalid, so that occupation of a message queue and generation of program playing misoperation are avoided.
In addition, in order to meet the requirements of the user, the embodiment sets a second state of delayed waiting for the message queue, considering that the user wants to see the program picture as early as possible when performing the continuous channel changing operation, the whole channel changing process needs to be smooth and not jammed, and the intermediate channels are played as much as possible. And after receiving a new message in the permanent waiting state and immediately playing the corresponding television program, controlling the message queue to enter a delay waiting state and starting timing by the timer. The two states of permanent waiting and delayed waiting can be characterized and assigned through different variable values. The corresponding delay time of the delay waiting is a preset set time, and the timing time of the timer is also the set time. The set time is the maximum time interval between two program broadcasts, and may be specifically set according to the system operation performance and the requirement of the user on the program broadcasting speed, for example, may be set to 1000 ms.
Step 207: if it is determined in step 205 that the message queue is not in a persistent wait state, the message queue is in a delayed wait state.
As described above, the judgment of the message queue status may be made by a preset status variable value. In this embodiment, the message queue has only two states, and if not a permanent wait state, is in a delayed wait state.
When the message queue is in the delay waiting state, if a new program playing command is received, the program playing parameter corresponding to the new program playing command is still inserted into the message queue, but the playing operation of the program is not responded. Also, during the delay wait state of the message queue, old, unresponsive program play parameters are overwritten with new program play parameters.
Step 208: and judging whether the delay time is up. If not, continuing to wait in the delayed time; if the time has arrived, go to step 209.
Step 209: and when the delay time is up, judging whether a new effective program playing parameter exists in the message queue. If yes, go to step 210; otherwise, go to step 202.
And when the timer is used for judging that the delay time is up, judging whether a new effective program playing parameter exists in the message queue. If not, it indicates that the user has not issued a new program playing command within the delay time. In this case, in order to reduce the resource occupation and quickly respond to the next program playing command, step 202 is proceeded to, the state of the message queue is set to be the permanent waiting state again, and the control processing procedure of playing the program is started from the permanent waiting state again.
Step 210: and when the delay time is up and new effective program playing parameters exist in the message queue, playing the television program corresponding to the effective program playing parameters received last in the message queue, and then setting the program playing parameters to be invalid. Then, go to step 202.
Receiving a new valid program playing parameter in the permanent waiting state of the message queue, as shown in step 206, will immediately execute the playing of the program, and then set the program playing parameter to be invalid, while controlling the message queue to enter the delay waiting state. In the process of the delay waiting state, if the effective program playing parameters are received again, the user sends a program playing command of channel changing within the set delay time. Because the delay time represents the maximum time interval between two channel switching, when the delay time reaches, only the television program corresponding to the effective program playing parameter received last in the message queue is played. If other program playing commands exist in the middle, the user is indicated to execute the continuous channel switching operation, and in order to avoid unsmooth response of each channel, programs corresponding to the middle program playing commands are filtered out and are not played any more. If the user does not change the channel continuously, but only performs the channel changing operation once in the delay time, the program can be ensured to be played normally.
After the last program playing command is executed, the program playing parameter is set to be invalid, and then the step 202 is proceeded to, the state of the message queue is set to be the permanent waiting state again, and the control processing procedure of the program playing is started again from the permanent waiting state.
The embodiment sets two states of permanent waiting and delayed waiting for the message queue, and controls the message queue to be continuously changed between the two states by combining the execution of program playing, thereby not only ensuring that the playing of the program corresponding to the program playing command sent by the user for the first time is immediately executed, improving the response speed of the program playing, but also ensuring that the playing of part of the program is omitted in the process of continuously changing the channel at a higher speed so as to ensure the fluency of continuously changing the channel, and ensuring that the program corresponding to the last program playing command sent by the user is normally played, thereby meeting the watching requirements of the user. Moreover, the whole playing processing process occupies less system resources such as a CPU and the like, and the utilization rate of the system resources is improved.
Fig. 3 is a block diagram showing the structure of an embodiment of the television program playback apparatus of the present invention.
As shown in fig. 3, the television program playing apparatus of this embodiment includes a program playing command receiving unit 31, a program playing parameter obtaining and writing unit 32, a message queue 33, and a program playing executing unit 34, where the connection relationship among the units and the function of each unit are as follows:
a program play command receiving unit 31 for receiving a program play command of a user;
a program playing parameter obtaining and writing unit 32, connected to the program playing command receiving unit 31, for obtaining a program playing parameter corresponding to the program playing command received by the program playing command receiving unit 31, and writing the program playing parameter into a message queue 33 connected to the program playing parameter;
a message queue 33 connected to the program playing parameter acquiring and writing unit 32 for storing the program playing parameters; and
and the program playing execution unit 34 is connected with the message queue 33 and is used for immediately or delaying to play the television program corresponding to the program playing parameter valid in the message queue according to the state of the message queue. The program playing executing unit 34 can execute the playing of the program according to the television program playing method shown in fig. 2, so as to improve the playing speed and the fluency of the program, and not occupy too many hardware resources of the television system.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
