B () is according to FM signal quality selection switching signal source.
Wherein, mobile media playing device first carries out step (a) the detection FM signal quality, judges FM signal product
Whether matter reaches the standard that can provide good media content, then performs step (b) switching signal source.That is, such as
Fruit finds that FM signal quality can reach standard, then continue with the FM signal converting media content for broadcasting, that is,
Select not switching signal source：Relatively, if it find that signal quality fails to reach standard, then selection switch to other signal sources with
The media content is persistently received, so that the normal play of the avoidance breakout media content.
It is worth mentioning that the mobile media playing device include it is various play one or more comprising sound, image,
And/or other sense organ contents seem one or more playing device of media of vibration or smell etc., such as vehicle-mounted radio, vehicle-mounted
TV etc..
It will be further appreciated that the signal source beyond the FM signal is in addition to it can be 4G signals, it is also possible to replaced
Change or increase be embodied as WiFi, bluetooth, bluetooth low energy (BLE), near-field communication (NFC), infra red data as-sodation standard (IrDA),
GSM signals, CDMA signals, TD-CDMA signals, 3G signals, Zigbee, the worldwide interoperability for microwave access
, and other other data transfer meanses known to those skilled in the art (WiMAX).Additionally, it is above-mentioned including FM signal and its
The frequency spectrum of his signal, channel, standard, analogy or numerical digit equal-specification and sending method are unrestricted.
Further, the step (b) also includes step：
(b1) other signal sources are detected；
(b2) basis signal quality and parameter setting selection signal source；
(b3) one or more signal sources are connected；With
(b4) inessential signal source is disconnected.
In other words, when performing step (b) switching signal source, the step (b1) is first carried out and detects other signals
Source, to obtain the situation of current signal source each in addition to FM signal, then performs the letter that the step (b2) is known according to detection
Number quality and device acquiescence or the parameter select signal source for adjusting afterwards or setting, then perform the step (b3) and connect one
Or more signal source, the step (b4) is finally performed again and disconnects inessential signal source.For example, if the step (a)
Testing result finds that the FM signal quality of script is below standard, then other signal sources will be detected at the step (b1), to institute
State the parameter that step (b2) can then be given tacit consent to according to device or adjust afterwards or set, and the result that the step step (b1) is obtained
Selection signal source, the step (b3) is then to connect one or more signal sources according to selection result, so that it is guaranteed that lasting obtain

After signal quality is up to standard, switching signal source returns FM signal by the step (b), may during other signals so as to avoid using
The service fee of generation.Furthermore, it is understood that when the step (b4) in the middle of the step (b) is gone to, it will be switched off adjusting
Signal source beyond frequency signal, or in the case where being set according to different parameters, may only disconnect some there may be expense or
Inessential signal source, for example, only disconnect 4G signals, but retain free WiFi signal.It is noted that in the step
(b3) connection mentioned in the middle of is not limited to two-way connection or communication, also comprising unidirectional reception and other connected modes.
Further, the FM signal changing method can also include step：
(c) buffered signal content.
When user determines the media content that the FM signal for playing certain channel using mobile media playing device is changed,
The mobile media playing device can perform step (c) the buffered signal content, that is, after first receiving the FM signal, will believe
Number content directly or after being converted to media content gives caching process, treats caching a period of time, such as after 5 seconds, then broadcast.This
When broadcast content be content before the cache-time, while still caching content for some time in device for switching signal source
Or caused delay buffering is used during other optimization broadcast content operations, so as to avoid the media content for broadcasting from occurring interrupting
Or poor quality situation.It is noted that the step (c) be also can operation in advance, that is, in user still
During the media content that determined is changed using the FM signal that mobile media playing device plays certain channel, mobile media plays dress
Put the content with regard to part specified channel or whole channels and perform the step (c), so as to determine to listen to or rating in user
Row waiting need not be cached again during the media content of certain specific channel, but still enjoy caching effect.
Further, described step (c) includes step：
(c1) signal source is judged；With
(c2) the parameter cache media content of basis signal source and setting.
Put it bluntly, because the mobile media playing device may be using FM signal and/or other signals as its media
Content sources, that is to say, that signal source may be cut after the mobile media playing device performs the step (a) and (b)
The signal source beyond FM signal, or connection simultaneously are shifted to including two or more signal sources including FM signal, therefore
Species to signal source during the step (c) has various possibilities.Now can respectively perform the step (c1) and judge letter
Number source and the parameter cache media content of the step (c2) basis signal source and setting.According to device give tacit consent to or afterwards adjustment or
The parameter of setting, can have difference in varied situations for the buffer memory of different signal source, therefore the mobile media is played
Device can directly be cached or be converted to by the signal of above-mentioned one or more signal sources according to parameter cache after media content for
It is follow-up to use or standby.
For example, when user has abundant 4G mobile communications flow of services or pays no attention to its service fee, can
More multi signal or media content are cached during being set to use 4G signal sources by parameter, so as to more be reduced when FM signal is not good
Dependence to FM signal, with obtain preferably, listening to or viewing experience smoothly.Again for example, for mobile communication stream
For the user that amount expense is considered, the default parameters of device can cache 4G signal source contents on a small quantity, once so that frequency modulation
The content and shape for being unlikely to still there are excessive use 4G signal source caches after FM signal are switched back into when signal quality is up to standard or recovers
Into waste.
It will be further appreciated that, when step (c2) is performed, due to being the parameter cache in basis signal source and setting
Media content so that parameter is not necessarily the same the signal source in addition to FM signal each other.For example, WiFi signal source is used
More multi signal or media content when Shi Keneng cachings are than using 4G signal sources.
Further, as shown in figure 1, the FM signal changing method also includes step：
D () successively plays media content.
When media content is played, commenced play out by the content start-up portion for caching, if cache contents deficiency then continues
Play to ensure that broadcasting is not interrupted using the content for being received from frequency modulation or other signal sources in real time.For example, in some fields
Although conjunction FM signal is not good but stills provide fuzzy media content reluctantly, if now lacking other signal sources again, slow
Deposit in the case that content runs out, for the broadcasting for ensuring media content is not interrupted, the sustainably poor tune of real-time playback quality
Frequency media content, with response to different demands such as urgent weather early warning.
