Description
Technical Field
The present application relates to the field of broadcast communication technologies, and in particular, to a method, a system, and a terminal device for controlling switching of a multi-channel broadcast tuner.
Background
Digital Audio Broadcasting (DAB for short) is a third generation broadcast following AM (amplitude modulation), FM (frequency modulation) and other analog signal broadcasts, and can receive pictures, text information and the like while listening to sound. Generally, there is a case where a DAB network topology exists for a region supporting DAB, and the same program is broadcast simultaneously in different DAB channels. Therefore, for the equipment supporting the double DAB tuner, when the currently listened DAB program signal is attenuated to a certain degree, in order to ensure the listening experience of a user, DAB-DAB switching can be realized so as to switch to the DAB program with the same content with good signal.
Since the FM coverage is larger than DAB, when there is no switchable channel signal in the current DAB, the FM channel of the same program can be switched, i.e., DAB-FM switching. When the DAB program with good signals is monitored subsequently, the FM-DAB switching is carried out from the FM switching to the DAB, namely the FM-DAB switching. Thus, management of switching control between these three tuners (DAB 1, DAB2, FM) is indispensable. However, in the conventional multi-tuner switching management method, such as DAB2-FM switching and FM-DAB1 switching, cumbersome attribute adding and deleting operations need to be performed, which results in low switching efficiency and certain risks.

The terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning that is consistent with their contextual meaning in the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in various embodiments.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments and features of the embodiments described below can be combined with each other without conflict.
Some abbreviations and terms mentioned in the embodiments of the present application are explained first.
Tuner: a tuner for broadcasting;
ACT: tuner currently used by foreground playing programs.
BGS: the background listens for tuners that have switchable programs.
Target: namely, the target tuner for switching the playing.
DABx and DABy, both belonging to DAB, when x =1, y = 2; when x =2, y = 1.
Please refer to fig. 1, which is a schematic diagram of a hardware structure of a terminal device supporting a three-way tuner (denoted as DAB1, DAB2, FM), wherein FM is analog signal broadcast, and DAB1 and DAB2 are both digital signal broadcasts. The three tuners are independent on hardware and are connected to the playing and displaying structure of the same radio equipment, and because the radio equipment can only play a certain broadcast signal in the foreground in the same time, the tuners are dynamically switched under different signal environments to ensure the user experience. However, in the existing multiplex broadcasting tuner switching scheme, although the switching between DAB and FM can be realized, there are two necessary steps as follows: firstly, after DAB2-FM switching, BGS is set to DAB2 from DAB 1; second, after FM-DAB1 is switched, if the ACT is DAB2 last time, the attribute of DAB2 needs to be removed, and meanwhile, a corresponding attribute needs to be added to DAB 1. Therefore, these steps increase the processing difficulty of BGS and ACT in software, and the complicated attribute adding and deleting operations increase the risk of abnormality and the like.
In order to solve the above problems, it has been analyzed that, although DAB1 and DAB2 belong to two structures in terms of hardware, only one set of buffer space is allocated in terms of software to store the attributes of pictures and texts to be played, which makes it necessary to reallocate the buffer space to a new DAB tuner each time in the above switching scenario. Therefore, the embodiment of the application provides a switching control method of a multi-channel broadcast tuner by improving the existing switching scheme. The method introduces two dynamic variables, and enables tuner of background monitoring before and after switching to be unchanged when switching from DAB to FM, namely before switching, DABx is monitored in the background, and after switching to foreground to play FM, DABx is continuously monitored in the background, so that the attribute of BGS is reserved; when FM is switched to DAB, the original DABy can be switched back again by reserving the attribute of DABY and designating Target as DABy, the original path return is realized, the operation of reallocating the buffer space is omitted, and the operations of adding and deleting the attributes of different DAB tuners are reduced.
Referring to fig. 2, a flowchart of a method for controlling switching of a multi-channel broadcast tuner according to an embodiment of the present application is shown. Exemplarily, the multiplex broadcast tuner switching control method includes:
step S110, under the condition that the foreground is currently playing the first channel of digital signal broadcast, the background is controlled to monitor the second channel of digital signal broadcast and the analog signal broadcast, and the digital signal broadcast being monitored by the background is recorded as the first dynamic variable and the digital signal broadcast being played by the foreground is recorded as the second dynamic variable.
In this embodiment, for convenience of describing two different digital signal broadcasts, DAB1 is used to represent the first digital signal broadcast, and DAB2 is used to represent the second digital signal broadcast, or vice versa. The first dynamic variable and the second dynamic variable are mainly used for recording states of the two paths of digital signal broadcasts at different moments, for example, X is used for recording digital signal broadcasts monitored by a background; and Y is used for recording the digital signal broadcast played by the foreground. For example, as shown in fig. 3, when DAB1 is currently being played, there are X = DAB2, Y = DAB 1; when DAB2 is currently being played, X = DAB1, and Y = DAB 2. It will be appreciated that these two dynamic variables are dynamically updated according to the broadcast status of the specific digital signal broadcast. If the FM is currently being played, X and Y will be maintained at the values before switching to FM.
In the process of background monitoring, the channel signals of the tuner playing in the foreground and the tuner monitoring in the background can be compared with the program information to calculate to determine whether to switch and switch the target to analog signal broadcasting or digital signal broadcasting. For example, if a certain channel listening to DAB2 or FM is also playing the same program information, and the signal strength of currently playing DAB1 is not enough, it may be determined to switch to the corresponding DAB2 or FM. It is to be understood that the present embodiment mainly proposes a handover management mechanism between multiple tuners, and a description of how to determine whether a handover target is a digital signal broadcast or an analog signal broadcast is not made herein.
Step S120, if it is detected that the analog signal broadcast needs to be switched, the analog signal broadcast is switched to a foreground broadcast state, and the background is controlled to keep monitoring the digital signal broadcast corresponding to the first dynamic variable.
Exemplarily, if it is monitored that the switching is required and the switching target is analog signal broadcasting, that is, the switching target at this time is DAB1-FM, the analog signal broadcasting FM is switched from the background monitoring state to the foreground playing state, and meanwhile, the background monitoring BGS is kept as DAB2 (monitoring DAB2 before switching).
Step S130, after switching to the foreground to play the analog signal broadcast, if it is detected that the digital signal broadcast needs to be switched to the digital signal broadcast, switching the digital signal broadcast corresponding to the second dynamic variable to the foreground playing state, and controlling the background to monitor the analog signal broadcast and the digital signal broadcast corresponding to the first dynamic variable.
Exemplarily, after switching to FM, as shown in fig. 3, background listening (i.e., BGS = X) may be continued for the digital signal broadcast corresponding to the first dynamic variable X, and when it is monitored that switching to the digital signal broadcast is possible, the Target is designated as the digital signal broadcast corresponding to the second dynamic variable Y (i.e., Target = Y) at this time, so as to switch to the digital signal broadcast which is played last time again. For example, when the front station is playing FM (i.e., ACT = FM), and the two dynamic variables are X = DAB2 and Y = DAB1, if it is monitored that FM can be switched to DAB, switching to Y corresponding DAB1 is designated, i.e., the second switching operation of FM-DAB1 is performed, and the background still keeps monitoring DAB2 while also monitoring FM again.
It can be understood that if foreground broadcast is FM, the search results of the two channels of digital signal broadcasts are the same under the same environment because the two channels of digital signal broadcasts are searched at the same time. Therefore, when it is sensed that switching to the digital signal broadcasting is required again, by designating the target as DAB1 which was played in the foreground last time, i.e., implementing the original path fallback, the attribute migration operation introduced by tuner switching can be reduced.
Further, as shown in fig. 4, for the step S110, the method further includes:
step S140, if it is detected that the digital signal broadcasting needs to be switched, switching the second channel of digital signal broadcasting being monitored by the background to the foreground broadcasting state, and switching the first channel of digital signal broadcasting being played by the foreground to the background monitoring state.
Step S150, then, the first dynamic variable and the second dynamic variable are updated, and the background is controlled to monitor the analog signal broadcast and the digital signal broadcast corresponding to the updated first dynamic variable.
For example, if it is assumed that the current foreground is playing the first path of digital signal broadcast (i.e. DAB 1), as shown in fig. 3, if it is monitored that switching to the digital signal broadcast is required, switching operation of DAB1-DAB2 is performed, i.e. foreground playing is set to DAB2, background listening is changed to DAB1, and FM is kept being monitored. It can be understood that, after the switching operation of DAB1-DAB2 is completed, the tuner currently playing in the foreground becomes DAB2 (i.e. ACT = DAB 2), and the tuner listening in the background becomes DAB1 (BGS = DAB1+ FM), so that the two dynamic variables X and Y need to be updated as follows: x = DAB1 and Y = DAB 2.
In one embodiment, the attribute configuration of the first path of digital signal broadcasting (DAB 1) can be controlled to be switched to the attribute configuration of the second path of digital signal broadcasting (DAB 2) for foreground playing. And simultaneously, controlling the first path of digital signal broadcast to carry out background monitoring according to the monitoring program list of the second path of digital signal broadcast. For example, the attribute configuration of each digital signal broadcast may include, but is not limited to, one or more combinations of text information (DLS), picture (slideshow), signal (signal), and the like.
It can be understood that, after switching to DAB2, it is also possible to switch from DAB2 to DAB1 again, as long as the corresponding switching conditions are met. The switching process of these two kinds of digital signal broadcasting is the same, and the description is not repeated here with specific reference to the above content.
Further, after the step S150, that is, after switching to the foreground to play the second channel of digital signal broadcast, the method for controlling switching of the multi-channel broadcast tuner may further include:
step S160, if it is detected that the analog signal broadcasting needs to be switched to, returning to step S120, namely, switching the analog signal broadcasting to a foreground broadcasting state, and controlling the background to keep monitoring the digital signal broadcasting corresponding to the first dynamic variable.
Exemplarily, after the first switching to the digital signal broadcasting, the monitoring may be continued, and if it is detected that the switching to the analog signal broadcasting is needed subsequently, the switching foreground is controlled to play the digital signal broadcasting as FM, and the background keeps monitoring the digital signal broadcasting DBA1 that was being monitored last time, that is, the digital signal broadcasting corresponding to the current first dynamic variable X.
To facilitate understanding of the various switching states between multiple tuners, a specific switching logic flow diagram is shown in fig. 5 for illustration. Assume that DAB1 is initially set to foreground playback and background monitoring is DAB2 and FM, i.e., ACT = DAB1, BGS = DAB2 and FM, when X = DAB2 and Y = DAB 1. Thus, the signal quality of ACT and BGS are tested to determine whether a handover is required, and the particular type of handover (FM or DAB). If the condition that switching to FM is required is monitored, ACT = FM and BGS = X are set; if switching to DAB is monitored, the Target can be set to Y, and if Y is DAB1, ACT = DAB1, BGS = DAB2 and FM can be set, where X = DAB 2; if Y is DAB2, ACT = DAB2, BGS = DAB1 and FM may be set, where X = DAB 1. Wherein each time the switching is completed, the step of detecting the signal quality of the updated ACT and BGS is returned to, thereby continuously switching back and forth between the various tuners.
It is understood that the three tuners can be dynamically switched with each other for multiple times according to actual environmental conditions, including switching back and forth between two tuners, switching between different types of tuners, and the like, as long as corresponding switching conditions are met. By defining two new variables and carrying out target designation when switching from analog signal broadcasting to digital signal broadcasting, the three kinds of broadcasting can realize the original path return of DAB1 or DAB2 in the switching process without carrying out operations such as back and forth deletion on the attributes of the DAB tuner before and after switching.
In the switching control method of the multiplex broadcast tuner in the embodiment of the application, two dynamic variables are introduced, a switching path from FM to DAB2 is added, and a method for dynamically specifying whether BGS is DAB1 or DAB2 is adopted in DABy-FM switching, so that before-switching BGS is DABx and after-switching BGS keeps DABx unchanged. In the subsequent FM-DAB switching, the target is dynamically designated as the DABy, so that the original reserved DABy attribute configuration is directly used after the switching without repeatedly performing attribute adding and deleting operations.
