FIG. 1 illustrates a flow chart of a method 10 of receiving a broadcast in accordance with an embodiment of the present invention.

When receiving the broadcast, in S11, the signal value S of the current broadcast channel is detected.

Assume that the broadcast channel predetermined signal threshold is T _s . In S12, the current broadcast channel signal value S and a predetermined threshold signal T _s comparison.

Assume that the count switching threshold of the broadcast channel preset is T _N . In S13, the broadcast channel signal when the current value of S is smaller than a predetermined threshold signal T _s is greater than the number of switching count threshold T _N, the current broadcast switching functions.

Therefore, the inconvenience caused by the change of the broadcast signal strength to the user is greatly reduced, and the user's feeling of listening to the broadcast is improved.

According to an embodiment of the present invention, when the signal value of the current broadcast channel is detected in S11, the signal value of the current broadcast channel can be periodically detected; it can also be detected only when the broadcast is turned on.

According to another embodiment of the present invention, in S13, the number of times that the signal value of the current broadcast channel is less than the predetermined signal threshold may be the number of times that the signal value of the current broadcast channel is continuously smaller than the predetermined signal threshold, or may be the signal value of the current broadcast channel.

The cumulative number of times may be the cumulative number of times that the signal value of the current broadcast channel is less than the predetermined signal threshold in the specified time period, or may be the accumulation of the signal value of the current broadcast channel less than the predetermined signal threshold after the broadcast is turned on. Number of times.

2 illustrates a flow chart of a method 100 of receiving a broadcast in accordance with an embodiment of the present invention.

When receiving the broadcast, in S110, the signal value S of the current broadcast channel is detected.

Assume that the broadcast channel predetermined signal threshold is T _s . In S120, the current broadcast channel signal value S and a predetermined threshold signal T _s comparison.

If the signal value S of the current broadcast channel is greater than or equal to the predetermined signal threshold T _s (corresponding to "No" in S120 in the drawing), then in S121, resetting the signal value S of the current broadcast channel is smaller than the predetermined signal threshold T The number of _s is zero, and in S122, the current broadcast channel continues to be received.

If the signal value S of the current broadcast channel is smaller than the predetermined signal threshold T _s (corresponding to "YES" in S120 in the drawing), then in S130, the number of times the signal value S of the current broadcast channel is less than the predetermined signal threshold T _s is updated, for example You can add 1 to the current number of times.

Assuming that the count switching threshold of the broadcast channel preset is T _N , then in S140, the number of updates in S130 is compared with the count switching threshold T _N . The count switching threshold T _N can be zero or a positive integer.

If the number of times is less than or equal to the count switching threshold T _N , then in S122, the current broadcast channel continues to be received (corresponding to "NO" of S140 in the drawing). If the number of times is greater than the count switching threshold T _N (corresponding to "YES" in S140 in the drawing), then in S150, the current broadcast function is switched.

As shown in Figure 2, switching the current broadcast function in S150 can include one of the following methods. Among them, in S1510, switching to the mute state; at S1520, switching to another broadcast channel; at S1530, switching to the local player; at S1540, turning off the broadcast.

The above various ways of switching the current broadcast channel may be one type or any combination thereof. The order of the combinations can also be prioritized according to user habits, preset by menu options, or selected to be turned on or off through menus. Taking a mobile terminal as an example, the local player may be, for example, an MP3 player, a video player, or a multimedia player.

In addition, in S1520 of Fig. 2, it is assumed that the currently saved channel list has C0, Cl, C2, -..,

C9, the corresponding channel signal strength is represented by S0, Sl, S2 S9, and the channel currently being listened to by the user is C0.

At this time, according to an embodiment of the present invention, when it is necessary to switch the current broadcast, it is possible to switch to another broadcast channel in the current broadcast list, such as C1 or C9. Another broadcast channel can be The next broadcast channel in the broadcast list is selected one by one, or in the order of priority, or another broadcast channel in the broadcast list is randomly selected.

When the signal strength of the broadcast channel is changed, the embodiment of the present invention adopts a method for switching channels on the broadcast list, which reduces the waiting time when manually switching, and improves the user's feeling of listening to the broadcast, thereby enhancing the user's relaxed and happy. Experience.

According to another embodiment of the present invention, in S1520 of FIG. 2, when switching to another broadcast channel to receive a broadcast, another broadcast channel may be searched for on the current broadcast spectrum, for example, FM (Frequency Modulation) broadcast. As an example, another broadcast channel can be searched for in the frequency language 87.5 kHz to 108.0 kHz and switched to the other broadcast channel that was searched. A search signal value may be larger than a predetermined threshold signal T _s broadcast channel. Further, other threshold values larger than the predetermined signal threshold T _s may also be used as the search condition.

At this time, one or more broadcast channels may be searched, and according to an embodiment of the present invention, the searched broadcast channels may be stored in the broadcast list.

When the signal strength of the broadcast channel is changed, the embodiment of the present invention adopts a method for automatically searching and switching on the entire spectrum of the current broadcast, which reduces the waiting time during manual search, and improves the user's feeling of listening to the broadcast, thereby enhancing The user has a relaxed and enjoyable experience.

Alternatively, the process of resetting the number of times (S121) in the method of FIG. 2 may be changed. For example, it may not be performed S121, i.e., may not be reset when the current broadcast channel signal value S is greater than or equal to a predetermined signal threshold T _s signal value S signal value of the current broadcast channel is less than a predetermined number of signal threshold T _s directly receiving a current Channel (S122).

As another embodiment, a period of the number of resets may be specified, S121 is performed after the specified period of time elapses, or S121 is performed after S150 is executed. The above variations are all within the scope of the embodiments of the present invention.
