Specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated it will be appreciated that preferred reality described herein
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Fig. 1 is a kind of flow chart of video cache method in the embodiment of the present invention.This video cache method is applied to terminal
In, wherein, terminal can be mobile phone, computer, digital broadcast terminal, messaging devices, game console, and flat board sets
Standby, Medical Devices, body-building equipment, personal digital assistant etc..As shown in figure 1, the method comprises the following steps S11-S13:
Step S11, during net cast, caches and is located in live list that the most front the first video item is corresponding to be regarded
Frequently.
Wherein, live list includes the video item of multiple not yet broadcastings, and the plurality of video item is according to playing sequence
Successively it is arranged in order.
Step S12, when receiving the refresh operation to live list, to the first video item, corresponding video delays for interruption
Deposit.
Step S13, after refresh operation terminates, continues to be located at video item pair the most front in the live list after cache flush
The video answered.
Using technical scheme provided in an embodiment of the present invention, live list middle position can be cached during net cast
In the corresponding video of the first video item the most front so that the video that will play can cache in advance, thus playing video
When more smooth without waiting for cache-time, the broadcasting of video, the experience of user is also just more preferably.Meanwhile, when receiving to live
During the refresh operation of list, interrupt the caching to the corresponding video of the first video item, and after refresh operation terminates, continue caching
It is located at the corresponding video of video item the most front so that the video caching in advance is live list all the time in live list after refreshing
In be located at the most front corresponding video of video item, thus ensureing need not use when playing the corresponding video of video item in live list
Family waits cache-time, and the broadcasting of video is more smooth, and makes the caching of video in live list more can meet live demand,
Improve the live viewing experience degree of user.
In one embodiment, as shown in Fig. 2 step S13 can perform as following steps S21-S23:
Step S21, judges whether live list is refreshed out the second new video item under refresh operation;If so, then hold
Row step S22;If it is not, then execution step S23.
Step S22, determines that the second video item is to be located at the most front video item in live list after refreshing, and continues to cache
The corresponding video of second video item.
Step S23, continues the caching corresponding video of the first video item.
In this embodiment, by judging whether live list is refreshed out the second new video item under refresh operation, and
Cache this corresponding video of the second video item when refreshing and the second new video item, and the second new video item not refreshing
Shi Jixu caches the corresponding video of the first video item of prior interrupt so that the video caching in advance is live list middle position all the time
In the corresponding video of video item the most front, thus ensureing to play during the corresponding video of video item in live list without user etc.
Treat cache-time, the broadcasting of video is more smooth, and make the caching of video in live list more can meet live demand, improve
The live viewing experience degree of user.
In one embodiment, execution step S23, that is, when continuing the caching corresponding video of the first video item, can perform and be
Following steps:First, determine that the corresponding video of the first video item is interrupted the interrupting information of caching;Secondly, according to interrupting information
Continue the caching corresponding video of the first video item.
In this embodiment, interrupting information includes break period and/or interruption position.Caching the is being continued according to interrupting information
During the corresponding video of one video item, can at the break period and/or interruption position start continue caching the first video item corresponding
Video.For example, when the corresponding video of the first video item is interrupted caching, the break period is at 20 minutes of this video, then continuing
During the continuous caching corresponding video of the first video item, still at 20 minutes of this video, continue caching, and need not opening from this video
Nose heave new caching.Again for example, when the corresponding video of the first video item is interrupted, interruption position is the 1000th frame of this video, then
When continuing the caching corresponding video of the first video item, still at the 1000th frame of this video, continue caching, and need not regard from this
The beginning of frequency caches again.
In one embodiment, when live list is refreshed out the second new video item under refresh operation, second regards
The front position that frequency item is located in live list, the second place that the first video item is located in live list.Now stop caching
The corresponding video of first video item, caches the corresponding video of the second video item.When the corresponding video cache of the second video item terminates
Afterwards, if not caching out new video item, break period when the corresponding video of the first video item is interrupted caching and/or
Continue the caching corresponding video of the first video item at interruption position.
In above-described embodiment, it is interrupted the interrupting information of caching, Jin Ergen by determining the corresponding video of the first video item
According to interrupting information cache the corresponding video of the first video item so that be interrupted caching video can at the break period or in
Start at disconnected position to continue caching, need not start anew to cache, it is achieved thereby that what the live video breakpoint that will play renewed
Effect, save caching flow ease up deposit the time.
