Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
A first embodiment of the disclosure is a switching method for playing channels, applied to a video playing device, for controlling switching among channels, as shown in fig. 3, the switching method includes:
step S1, when a switching instruction for playing a video is received, determining whether channel program information corresponding to the switching instruction is cached in a memory.
When the video playing device receives a channel switching instruction, whether the channel program information corresponding to the switching instruction is cached on a program linked list analysis module for analyzing the information of the program linked list is judged. If the cache is present, step S2 is executed, and if the cache is not present, step S3 is executed.
Furthermore, the interface chain list analyzing module is only used for acquiring and analyzing the program information of the channel chain list and the program chain list in the prior art, and the channel management module triggers video playing according to the analyzed channel chain list and the program information contained in the program chain list, so that the program chain list analyzing module in the step not only has the function of analyzing the channel program information, but also has a storage function, caches the acquired and analyzed channel program information, and avoids the time consumed by repeated requesting, acquiring and analyzing when the channel program information needs to be acquired again.
Step S2, if the channel program information corresponding to the switching instruction is cached in the memory, directly obtaining the channel program information from the memory, and playing the program according to the obtained channel program information.
If the channel program information corresponding to the switching instruction is cached in the memory of the program linked list analysis module, the corresponding channel program information can be directly found out from the cache, so that the time for acquiring the channel program information again is saved.
It is conceivable that the plurality of channel program information cached in the memory of the program linked list parsing module are stored in the form of a two-dimensional program linked list. The corresponding channel program information can be conveniently and quickly searched after the plurality of channel program information are cached.
And in order to avoid that the information stored in the memory of the program linked list analysis module is overdue, the program linked list stored in the memory of the program linked list analysis module needs to be updated regularly, and the newly added channel program information is added to the tail of the program linked list.
Specifically, the version of the program linked list is judged first when the data of the new program linked list is taken each time, the updated list is stored into the linked list if the updated list is updated, the updated list is covered when the data is updated, and the new program linked list is added to the tail of the linked list.
Step S3, if the channel program information corresponding to the switching instruction is not cached in the memory, requesting to acquire the channel program information corresponding to the switching instruction, caching the received channel program information in the memory, and playing the program according to the acquired channel program information.
If the channel program information corresponding to the current switching instruction is not cached in the memory of the program linked list analysis module, the channel program information corresponding to the current switching instruction is requested to be acquired, and is cached in the memory of the program linked list analysis module for storage after being analyzed, so that when the channel is switched to again, the channel program information can be directly acquired from the memory, and the time for repeatedly acquiring and analyzing is saved.
Optionally, before the step of triggering the playing module to play the program according to the obtained channel program information, the channel management module further includes:
establishing at least two channel playing threads according to the sequence of the channels in the channel chain table;
and the channel playing thread corresponding to the switching instruction analyzes and pushes data to play, and other channel playing threads only analyze and cache the channel program information corresponding to the channel playing thread.
In order to realize the channel switching more quickly, the steps also adopt the establishment of a plurality of channel playing threads and the preloading of the channel program information to be played, thereby realizing the faster channel switching.
Specifically, when a plurality of channel playing threads perform audio/video signal transmission, in order to realize control among the plurality of channel playing threads, the method further includes:
judging whether a channel playing thread is established on a channel after switching corresponding to the received switching instruction;
if the channel is established, controlling to switch the current channel playing thread into a dormant thread, and simultaneously switching the switched channel playing thread into a full-resolution playing thread;
otherwise, increasing the channel playing thread after switching corresponding to the switching instruction, and performing full analysis playing on the channel playing thread.
After receiving a switching instruction, acquiring channel program information corresponding to the switching instruction, and then judging whether a playing thread of the channel is established, if so, directly switching the current channel playing thread to the channel playing thread corresponding to the switching instruction, if not, adding the channel playing thread corresponding to the switching instruction, and performing video playing control on the channel playing thread.
Further, in a specific embodiment, the established multiple channel playing threads may be preset for the user, or may be automatically established by the system according to the program sequence on the channel chain table, so that if the control mode of the user selects on-demand, the system cannot preload the next channel to be switched, and if the control mode of the user selects to load according to the channel arrangement sequence, the channel switching can be completed quickly by using the method for preloading the multiple channel playing threads in the above steps. It is conceivable that the system may also establish and preload multiple channel playing threads according to a channel playing sequence table set by a user in a self-defined manner.
In specific implementation, each channel can start a thread for requesting and analyzing audio and video data, but only the current channel needs to transmit the decoded data to the player for playing. Because such a method may occupy some CPU resources, it is suggested that the parsing threads of non-current channels increase sleep delay and frame loss measures, and the number of threads is set, preferably, three channel playing threads are established, one parsing thread of current channel, one preloading thread of previous channel, and one preloading thread of next channel (here, the preloading thread refers to a thread that does not transmit data to the player).
To realize a more detailed analysis of the present invention, the following further analyzes the present invention with reference to specific examples thereof.
When the method disclosed by the invention is used, as shown in fig. 4, the method comprises the following steps:
j1, receiving the operation of channel switching instruction sent by the user;
j2, the channel management module sends out a request program linked list analysis module to obtain information of SLS data of the channel corresponding to the channel switching instruction;
j3, determining whether the channel program information corresponding to the switching instruction has been cached in the memory by the program chain table analyzing module, if yes, executing step J6, and if not, executing step J4;
j4, MMTP module filters and returns SLS data;
j5, program chain list analysis module analyzes the returned SLS data and buffers it into its memory;
j6, the channel management module triggers a playing thread according to the obtained SLS data;
j7, the thread A is the channel switched to corresponding to the current switching instruction, firstly, the audio and video data corresponding to the received channel program information is filtered, and the step J10 is executed;
j10, MMTP filtering and analyzing the A/V data received by the channel A, then executing the step J13;
j13, pushing the analyzed A/V data of the channel A to a player for playing; then step J16 is performed;
j8, the thread B is a channel corresponding to the non-current switching instruction, the audio and video data corresponding to the received channel program information are filtered, and the step J11 is executed;
j11, performing frame skipping analysis on the video data information of the thread B, and executing a step J14; then step J16 is performed;
j14, performing frame loss and dormancy processing on the video data information of the thread B;
j9, the thread C is a channel corresponding to the non-current switching instruction, the audio and video data corresponding to the received channel program information are filtered, and the step J12 is executed;
j12, performing frame skipping analysis on the video data information of the thread B, and executing a step J15; then step J16 is performed;
j15, performing frame loss and dormancy processing on the video data information of the thread B;
j16, playing by the player.
The time consumption for repeatedly analyzing the program linked list (SLS) is reduced by using the program linked list analyzing module for caching, and the time consumption for re-filtering and analyzing A/V data by using MMTP is reduced by using multithreading, so that the channel changing efficiency can be greatly improved. Meanwhile, the number of threads is set to be 3, and the threads of the non-current channel perform frame skipping and frame loss analysis and sleep thread operation, so that the consumption of CPU resources is reduced.
