Brief description of the drawings
Accompanying drawing 1 is the multithreading buffering schematic diagram of the present invention.
Embodiment
A kind of DST PLAYER intelligent buffer method to the present invention is described in detail below below in conjunction with the accompanying drawings.
Difference with the prior art of the present invention is the video-audio signal exported from multichannel is expanded to all the way, so as to reflect
Multiple scenes.A kind of DST PLAYER intelligent buffer method is provided as shown in Figure 1, and its specific way to play for time is：
First, multithreading is set to accelerate buffering：The head pointer and tail pointer of played data are recorded, judges whether to reach spy
Fixed multithreading buffer condition, after reaching, segmentation is divided, and the thread for starting response goes download request data, specific numerical value, according to
Rely in specific network environment, server film source definition and player configuration, it is interior between above-mentioned head pointer and tail pointer
Hold videlicet by the content of broadcasting.
The detailed content of the step one is：Player safeguards the buffering list of a ring-type, for buffering from server end
The data of acquisition, are played out during player plays by specific interface data therefrom, and the size of buffering area is according to each
From situation be designed.
Program should safeguard an idle head start pointer（It that is to say valid data tail pointer）With idle end tail pointers
（Namely cable data head pointer）, data between the two are invalid datas, outside data be effective non-played data
（Player can obtain data therein by special interface）.
When idle data exceedes critical value, start multithreading and download, according to specific network environment and buffer size, draw
Divide the thread of varying number, download work while starting, current freebuf, notes the response that upgrades in time until filling up
Pointer position.
The 2nd, rational buffering consumption and triggering buffering are set：The design of buffering strategy, is related to several factors.Need
A mathematical modeling is used to go modeling Simulation.Assuming that average download of certain section of Time-Client OTT box from streaming media server
Speed S（Note S and non-constant be continually changing over time）, the video code rate of client's program request（Or film source definition）
M, the psychology of people receives interim card time T（Less than this time, people will feel frequent interim card when program is watched）.
Must more clearly be, S<The phenomenon of pause definitely occurs in M, but appearance is " frequently to block in the short time
" still " pause buffering for a long time ", it is just relevant with buffering strategy.S>M is just as local broadcasting, all without buffering.It is most rational
Scheme is the T according to M and real-time S customizations, at regular intervals, buffering strategy is adjusted at any time.User's impression had so both been looked after,
Performance is taken into account again.
First we to discuss that our buffering area should be set to much suitable, understand that minimum should be no for M*T from definition
Then in M under 0 limiting case, client may feel interim card.If hardware RAM configurations are big, it can suitably increase buffering area big
It is small.Currently a popular hardware configuration can be buffered 1 minute or so, and T is about within 3s.
, can in order to avoid frequently interim card after in DSR, it is possible to which the player of transmission plays out processing
Know that can just be sent to player when minimum is M*T buffering capacity plays out.Therefore will when buffer interface design is carried out
Note, if ineligible, allow player pause to wait.
When multithreading download mechanism should be being triggered, start several threads on earth, also reasonably to design, it is to avoid cause
The too high situation of cpu utilization rates.The suggestion of this explanation starts a thread, and once buffering is done per T/2 and is checked, if clear area
Then start multithreading download more than T/2*M.The data volume that each thread is responsible for T*2*M is downloaded.By practice, the processing can be with
Saving cpu again can efficient buffered data.
Embodiment：Assuming that certain hardware employs 1G ram, except operating system takes residue 600M memory headrooms.Assuming that
The speed that the ott boxes of certain client are downloaded from piece source server be 1M/S it is believed that highest time of frequent interim card be 3S,
Film source code check is 2M/S, then the phenomenon of pause buffering will necessarily be produced when the client watches, in order to avoid prolonged temporary
Stop and frequently Caton phenomenon occurs, it is proposed that player does following operation.
Application 240M internal memories are used to build circular buffering first, can start 240/ (3*2*2)=20 at the beginning（If thread
Excessively, cpu utilization rates be result in too high, can according to circumstances limits number of threads）, while initiating download request to server.
Start detection buffering thread every 3/2=2s or so left detection simultaneously, when reaching 2*3=6M, but played data, it is same due to broadcasting
When, data are filled up in backstage quickly in buffered data, while there is the detection of detection thread, player can be maximum to the greatest extent
It is steady to play, so as to improve Consumer's Experience.
It is the known technology of those skilled in the art in addition to the technical characteristic described in specification.
