Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment belongs to the scope of protection of the invention.
Embodiment one, the present embodiment, which proposes a kind of multiple-format video media and passes through, broadcasts control method, as shown in Figure 1, including
Switch step between format, switch step includes following sub-step between the format：
S11, system initialization are opened and play the video information in initial format；
S12, judge whether to need to switch format, if desired, then control continues to play the video information of current format, simultaneously
The information of new format is being loaded from the background；
S13, the whether equal loaded of video for judging all display areas in new format, if so, and the new format of display,
Original format set type is closed, otherwise, continues to play original format set type, and repeats step S13.
The multiple-format video media of the present embodiment, which passes through, broadcasts control method, when receiving external system format switching command,
System continues to play current format, while is loading new format from the background, when detecting that the video in new format all has the picture defeated
New format is played after going out, just close original format set type, so can effectively prevent due to new format has not loaded and original format set type stop
Blank screen, interim card etc. caused by words play incoherent phenomenon, especially for the switching of multiple-format video, video playing continuity
It is good.
In the present embodiment, switch step between video is further included in same format, as shown in Fig. 2, in the same format
Switch step includes following sub-step between video：
S21, two video modules are respectively created for each video display area, and make two video module position weights
It closing, described two video modules are respectively the first video module and the second video module, wherein, first video module is upper
Layer playing module, the video played for this video display area to be loaded currently to need, and play out, second video screen module
Block is lower floor's playing module, and for loading the next video to be played of this video display area, second video module adds
When carrying video, by video mute；
S22, judge whether to need Switch Video, if desired, then perform step S23；If need not, repeat step
S22；
Whether S23, detection second video module are completed to load and have picture output, if second video module is examined
It surveys this module to have completed to load and had picture output, then performs step S24a；Otherwise, step S24b is performed；
S24a, the second video module is placed in upper strata, switchs to upper strata playing module, while open sound；
24b, time-out is judged whether, if being not timed-out, return to step S23 if overtime, shows what video was loading
Animation.
By the way that two video modules are respectively created for each video display area in step S21, a video module is used for
Foreground plays, another video module for loading from the background, and when needing Switch Video, the video of backstage loading can directly be cut
Foreground broadcasting is shifted to, it, cannot be defeated in time due to new video loading buffering etc. when can effectively prevent due to regarding inter-frequency handoff
Go out, caused by blank screen, interim card etc. play incoherent phenomenon, especially for the switching between video in same format, video playing
Continuity is good.
In the step S11, during system initialization, calculate video that each video display area to be played and its start-stop is broadcast
It puts the time, and is put into caching.By calculating video and its beginning and ending time that each video area to be played in advance, and put it into
Caching, avoids causing precisely to cut according to time point due to recalculating overlong time when detecting video switching time point
It changes, shows format so as to most fast.When format switches, calculated according to the beginning and ending time recorded in caching and current time
Its initial position, due to just being switched over after the completion of the loading of new format, switching time is extremely short, can be neglected, so as to ensure to regard
Frequency is coherent to be played.
In the step S12, judge whether that the method for switching format is needed to reach what is stored in caching by judging whether
Format switching time point or the switching format order for whether receiving external system transmission.Wherein, according to judge whether to
The mode of the format switching time point stored up in caching judges that can set will such as reach predefined switching time point
It is defined as：It is reached in 1 second, so can be that new edition formula is reserved with certain buffer time, when preventing from switching due to new format not
The blank screen phenomenon for finishing and occurring can be buffered in time, cut again when arrival time point is waited if completion was preloaded in 1 second
It changes.
In the step S12, judge to switch version by judging whether to reach the format switching time point stored in caching
Formula method is the time point for detecting whether to reach format switching, if not reaching, is judged as that format need not be switched, returns to step
Rapid S12 continues to play the video in current format, otherwise, is judged as needing, and control continues to play the video letter of current format
Breath, while in the information for loading new format from the background.Technology is preloaded using format, is opened up after video loaded in format
Show, ensure when format switches without blank screen phenomenon；If the video in new format preloads time-out, system is prompted just in animated way
In loading video, picture interim card is avoided.
In the step S13, if the inwhole loadeds of the video of all display areas in new format, and in original format set type extremely
The video of few one of display area, which played, to be finished, then judges whether time-out, is judging the whether overtime step of format switching
In, including time threshold △ T2, the timing since the video playing of the display area finishes the time, if new format in the △ T2 times
In the videos of all display areas be fully completed loading, then be judged as not overtime, otherwise, be judged as time-out and played in video
The display area finished shows the animation that video is loading.When this mode can ensure to switch between two formats, each video
The fluency of display area if interval is smaller, will not bring vision interim card effect by the way of frozen frame to user, moreover, when
Between threshold value △ T2 for example could be provided as 300 milliseconds, can complete to buffer and export picture for 300 milliseconds under normal circumstances；It is if super
300 milliseconds are crossed, then easily causes obvious vision interim card, video is played when this step is by more than 300 milliseconds and is being loaded
Animation, mitigate user viewing when interim card effect.
In the step S22, judge whether that Switch Video is needed to comprise the following steps：
Judge whether the first video module finishes, if it is not, Switch Video is then not required, first video module after
Continued broadcasting is put, if so, needing Switch Video, and picture still is played to the last frame of video in the first video module, so
The judgement in step 23 is performed afterwards.
When judging whether time-out in the step S24b, including time threshold △ T1, finished from the first video module
Start timing, if in the △ T1 times the second video module complete loading, be judged as it is not overtime, otherwise, be judged as time-out and
The video region shows the animation that video is loading.The principle of this step is identical with the principle switched between format, if
Every smaller, video frequent switching will not be caused, moreover, time threshold △ T1 for example could be provided as 300 milliseconds, under normal circumstances
300 milliseconds can complete to buffer and export picture；If more than 300 milliseconds, easily cause obvious vision interim card, this step
The animation that video is loading is played during by more than 300 milliseconds, mitigates interim card effect of the user in viewing, avoids being considered
Video is stuck.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
The variations, modifications, additions or substitutions that the those of ordinary skill in domain is made in the essential scope of the present invention, should also belong to this hair
Bright protection domain.
