| NumKeyFrame | 0 | 1 | 1 | 1 | 1 | 1 |
The structure of the Array for structural body of the logical frame is described below in detail, the Array for structural body specifically includes following two
Point：
Logical frame (FrameIndex), also known as logic frame index, each logical frame are arranged in Array for structural body by playing sequence
Row, it is corresponding with the position that array element indexes ArrayIndex instructions, i.e. logical frame A, logical frame B, logical frame C, logical frame
D, logical frame E are stored in the Array for structural body by playing sequence, and wherein logical frame B is repeated playing once, using with for the first time
Play different another array element storages, the value increase by 1 of array element index.
Add up the number (NumKeyFrame) of key frame that occurred before each logical frame, it is necessary to explanation, when
If preceding logical frame key frame, then the corresponding NumKeyFrame stored counts of current logic frame, i.e. by current logic frame
NumKeyFrame number increase by 1.For example, logical frame B is key frame in table 1, before without key frame, then by logical frame B's
NumKeyFrame records are revised as 1 by 0.When logical frame B is repeated playing again, not repeat count key frame, therefore the structure
The NumKeyFrame for each logical frame played in array after logical frame B is recorded as 1.
Position of the logical frame in Array for structural body, can be by the letter of the Array for structural body of the logical frame itself preservation
What breath was determined, be stored with its own position in Array for structural body in each logical frame, and the information is in the Array for structural body
Record is in each logical frame while generation.For example, playing the logical frame of end for C, its recorded in logical frame C is in table 2
Array for structural body in corresponding ArrayIndex be 3, it is determined that logical frame C first position be 3.
In the embodiment of the present invention, the logical frame that the broadcasting terminates is F, structures of the logical frame F in the logical frame generated

Whether the number of the accumulative key frame occurred is identical before frame；
The corresponding NumKeyFrame of ArrayIndex1 are searched in the Array for structural body, and, search ArrayIndex2
Corresponding NumKeyFrame, judges that ArrayIndex1 corresponding NumKeyFrame and ArrayIndex2 are corresponding
Whether NumKeyFrame is identical.
For example, it is specific as shown in table 1, if the first position is 1, the corresponding NumKeyFrame in Array for structural body
For 1, if the second place is 4, corresponding NumKeyFrame is 1 in Array for structural body, judges this two
Whether NumKeyFrame is identical.
If identical, step S103 is performed；If differing, step S104 is performed.
S103, confirm between logical frame and next logical frame to be played that the broadcasting terminates without key frame, and broadcast
Put next logical frame to be played；
If the corresponding NumKeyFrame of ArrayIndex1 NumKeyFrames corresponding with ArrayIndex2 is identical, really

S104, first key frame between the logical frame and next logical frame to be played that the broadcasting terminates is searched,
And play the first key frame.
If the corresponding NumKeyFrame of ArrayIndex1 NumKeyFrames corresponding with ArrayIndex2 is differed,
The first key frame between logical frame F and logical frame F ' can be searched by Predistribution Algorithm, and plays the first key frame.
In an example, referring to table 2, the logical frame that end is played in Array for structural body is B, and logical frame B is first
Secondary to play, its corresponding first position is 1, and corresponding NumKeyFrame is 1, next logical frame D to be played second
4 are set to, corresponding NumKeyFrame is 1, and this two NumKeyFrame are identical, therefore, directly play logical frame D.
In another example, referring to table 2, the logical frame that end is played in Array for structural body is A, logical frame A correspondences
First position be 0, corresponding NumKeyFrame is 0, and the next logical frame D to be played second place is 4, corresponding
NumKeyFrame is 1, this two NumKeyFrame differences, therefore, searches the first key between logical frame A and logical frame D
Frame, i.e. logical frames different from logical frame A first NumKeyFrame, is first key frame.In table 2, first
Logical frames different from logical frame A NumKeyFrame is B, i.e. logical frame B is the key frame found, plays logical frame B.
In the embodiment of the present invention, after the broadcasting of each logical frame terminates, pass through and confirm in the Array for structural body generated
The first position for the logical frame that the broadcasting terminates and the second place of next logical frame to be played, and judge first position and
Whether the corresponding number of key frame for adding up to occur before current logic frame is identical respectively for the second place, to judge that this is broadcast
Put and whether there is key frame between the logical frame of end and next logical frame to be played, if nothing, play this next
Logical frame to be played, if so, then searching the head between the logical frame and next logical frame to be played that the broadcasting terminates

The time complexity searched is reduced, the calculating time is largely accelerated, the fluency that picture is played is improved.
Fig. 2 is referred to, the key frame recognition methods that Fig. 2 provides for second embodiment of the invention can be applied in terminal, should
Method includes：
When S201, client terminal start-up loading Initial page, according to reproduction time sequential storage logical frame to be played, and remember
Add up the number of key frames occurred before recording each logical frame, obtain the Array for structural body of logical frame；
The client can be game class client, the client terminal start-up, after game initial picture starts to load and rendered
Display is on a terminal screen.Game picture is carried in client terminal start-up, while generating the structure of each logical frame of the game picture
Array.According to the logical frame that reproduction time sequential storage is to be played in the Array for structural body, and, record each logical frame it
The number of key frames of preceding accumulative appearance.
Specifically, the Array for structural body includes：The logical frame that is arranged by playing sequence and add up before each logical frame
The number of the key frame occurred.The Array for structural body one array element of each row correspondence, each array element correspondence binary
Group (FrameIndex, NumKeyFrame).
The Array for structural body specifically includes following two parts：
Logical frame (FrameIndex), also known as logic frame index, each logical frame are arranged in table by playing sequence, with array
Element index is corresponding, i.e. logical frame A, logical frame B, logical frame C, logical frame D, logical frame E are stored in the knot by playing sequence
In structure body array, wherein logical frame B is repeated playing once, is stored using different array elements are played from first time, array member
Plain index value increase by 1；
Add up the number (NumKeyFrame) of key frame that occurred before each logical frame, it is necessary to explanation, when
If preceding logical frame key frame, then perform stored count, the NumKeyFrame of current logic frame number is increased by 1.
Set array element to index (ArrayIndex) for array element, represent the playing sequence and logical frame of logical frame
Storage location.
The concrete structure of the Array for structural body of logical frame is identical with the table 1 of aforementioned first embodiment, ArrayIndex with
Corresponding relation between FrameIndex, NumKeyFrame is identical with the table 2 of aforementioned first embodiment.
Further, if same logical frame is repeated playing repeatedly, in the Array for structural body, repeated playing according to this
The playing sequence of logical frame, the logic repeated playing is stored using the array element of quantity identical with logical frame broadcasting time
Frame a, i.e. logical frame plays how many times, just corresponds to according to playing sequence using how many array elements to patrolling for repeating playing
Frame is collected to record respectively.For example, in table 2, logical frame B is played 2 times, just according to playing sequence, in ArrayIndex1 and
The ArrayIndex2 storage logical frame B of two positions 2 times.
S202, it is each logical frame according to storage location generation array element index, and records logic in each logical frame
Position in each comfortable Array for structural body of frame；
Index, can be indexed according to array element rapidly true according to storage location generation array element for the logical frame of storage
Position of the logical frame in the Array for structural body is determined, so as to accelerate to judge, search the speed of key frame.
Meanwhile, the position in each comfortable Array for structural body of logical frame is recorded in each logical frame, by inquiring about each logic
Frame can know storage location of each logical frame in the Array for structural body.Further improve and confirm logical frame in the structure
The convenience of position in array.
S203, after each logical frame is played and terminated, confirm logical frame that the broadcasting terminates in the structure generated
First position in array, and determine next logical frame to be played in the Array for structural body according to the first position
The second place；
In the embodiment of the present invention, the logical frame that the broadcasting terminates is F, structures of the logical frame F in the logical frame generated
First position in array represents that next logical frame to be played is F ', logical frame with array element index ArrayIndex1
The second places of the F ' in the Array for structural body is represented with array element index ArrayIndex2.
The information that can be recorded by query logic frame F, knows ArrayIndex1.For example, in table 2, playing patrolling for end
Volume frame is E, and logical frame E corresponding ArrayIndex in Array for structural body are 4, logical frame E Array for structural body generate it is same
When also record position from Array for structural body, pass through query logic frame E record information, it may be determined that logical frame E's
Position is 4.
After the broadcasting of each logical frame terminates, ArrayIndex2 can be according to ArrayIndex1, logical frame F and logic
The broadcasting time difference between frame F ', and, the isochronous surface length of default each logical frame is determined jointly.
Specifically, after logical frame F broadcastings terminate, logical frame F broadcast start time T1, logical frame F ' beginning is obtained
Reproduction time T2, each logical frame average time slice length L, wherein logical frame F ' broadcast start time T2 is logic
Frame F end reproduction time.The isochronous surface of multiple logical frames may be occupied between time interval [T1, T2], according to patrolling
Collect the average duration slice length of frame, the second places of the calculating logic frame F ' in the Array for structural body.
It is ArrayIndex1 to make the first position, and it is ArrayIndex2 to make the second place, then：
ArrayIndex2=ArrayIndex1+ (T2-T1)/L
S204, judge in the Array for structural body, the first position and the second place are corresponding in current logic respectively
Whether the number of the accumulative key frame occurred is identical before frame；
The corresponding NumKeyFrame of ArrayIndex1 are searched in the Array for structural body, and, search ArrayIndex2
Corresponding NumKeyFrame, judges that the ArrayIndex1 corresponding NumKeyFrame and ArrayIndex2 searched are corresponding
Whether NumKeyFrame is identical.
If identical, step S205 is performed；If differing, step S206 is performed.
S205, confirm between logical frame and next logical frame to be played that the broadcasting terminates without key frame, and broadcast
Put next logical frame to be played；
If the corresponding NumKeyFrame of ArrayIndex1 NumKeyFrames corresponding with ArrayIndex2 is identical, really
Recognize between logical frame F and logical frame F ' without key frame, can all skip, directly play logical frame F '.
If the probability that key frame occurs is p, by contrasting the key frame for adding up to occur before current logic frame
Number, confirm between the logical frame and next logical frame to be played that the broadcasting terminates without key frame, can all skip,
Next logical frame to be played is directly played, time complexity can be reduced, the time complexity after reduction is non-key
The probability (1-p) of frame is multiplied by query time O (1), i.e. O (1-p).
S206, first key frame between the logical frame and next logical frame to be played that the broadcasting terminates is searched,
And play the first key frame.
If the corresponding NumKeyFrame of ArrayIndex1 NumKeyFrames corresponding with ArrayIndex2 is differed,
By binary chop algorithm, the position that the first NumKeyFrame between logical frame F and logical frame F ' changes is searched.I.e.
The minimum corresponding logical frames of array element of ArrayIndex are searched, and meet the logical frame in the Array for structural body
NumKeyFrame value is (F.NumKeyFrame+1), wherein, F.NumKeyFrame is in Array for structural body
The number of the key frame for being accumulated to logical frame F of the corresponding position records of ArrayIndex1.
Wherein, binary chop algorithm is also known as binary search algorithm, it is adaptable to infrequently change and search frequently have sequence
Table, the binary chop algorithm is in having the array of repeat element, to search the position that object element occurs first, advantage is to compare
Number of times is few, searches speed soon, average behavior is good.
Specifically, in the present embodiment, the Array for structural body two positions ArrayIndex1 and ArrayIndex2 are divided
Not corresponding NumKeyFrame values compare, if identical, illustrate between ArrayIndex1 and ArrayIndex2 without key
Frame, directly plays the logical frame at ArrayIndex2；If it is different, then illustrate ArrayIndex1 and ArrayIndex2 it
Between have key frame, now need occur the position of key frame between binary chop ArrayIndex1 and ArrayIndex2 first,
That is NumKeyFrame value is patrolling for (F.NumKeyFrame+1) first between lookup ArrayIndex1 and ArrayIndex2
Collect frame.Binary chop algorithm search key frame process be：ArrayIndex1 and ArrayIndex2 average value are taken first
Mid, if the NumberKeyFrame values at mid positions are smaller than (F.NumKeyFrame+1), [mid+1,
ArrayIndex2] between search NumKeyFrame value first be (F.NumKeyFrame+1) element；If mid positions
The NumberKeyFrame values at place are bigger or equal with (F.NumKeyFrame+1) than (F.NumKeyFrame+1), then exist
The value that NumKeyFrame is searched between [ArrayIndex1, mid] is the logical frame of (F.NumKeyFrame+1) first, until
The left margin of binary chop is more than or equal to right margin, then stops searching.Now, the logical frame at left margin is first
NumKeyFrame value is the logical frame of (F.NumKeyFrame+1), so the logical frame at the left margin is appearance for the first time
Key frame, the logical frame of lookup is defined as between the logical frame and next logical frame to be played that the broadcasting terminates
First key frame, and play the logical frame.
If the probability that key frame occurs is p, then by by binary chop algorithm, searching the logic that the broadcasting terminates
First key frame between frame and next logical frame to be played, and the first key frame is played, the time that can reduce answers
Miscellaneous degree, the time complexity after reduction is multiplied by query time O (logn), i.e. O (p*logn) for the Probability p of key frame.
In the embodiment of the present invention, after the broadcasting of each logical frame terminates, pass through and confirm in the Array for structural body generated
The first position for the logical frame that the broadcasting terminates and the second place of next logical frame to be played, and judge first position and
Whether the corresponding number of key frame for adding up to occur before current logic frame is identical respectively for the second place, to judge that this is broadcast
Put and whether there is key frame between the logical frame of end and next logical frame to be played, if nothing, play this next
Logical frame to be played, if so, then searching the head between the logical frame and next logical frame to be played that the broadcasting terminates
Individual key frame, and the first key frame is played, judgement can be simplified, the process of key frame is searched, the speed for searching key frame is improved,
The time complexity searched is reduced, the calculating time is largely accelerated, the fluency that picture is played is improved.
