Vertical described first caching mapping table.Further, also described resource size, described suffix name and partial bytes can be formed
Character string sets up the first caching mapping table as described key assignments.
S13: according to described first caching mapping table by described image cache in this locality, i.e. caching and local electronic equipment
In.
In the present invention one specific embodiment, also include: ask when receiving to download from a picture controlling end download pictures
When asking, obtain suffix name and the resource size of picture to be downloaded from described control end, and according to described preset rules from described control
End processed obtains the partial bytes of picture to be downloaded；Search whether this locality exists and figure to be downloaded according to described first caching mapping table
The suffix name of sheet, resource size and the picture of partial bytes coupling；If existing, the most directly obtain the most buffered local figure
Sheet；If not existing, then download described picture to be downloaded to the request of described control end.Described control end for example, smart mobile phone or electricity
The smart machines such as brain.Using suffix name, resource size and partial bytes is that key assignments sets up the first caching mapping table, because existing
In some part electronic equipments, such as Semen setariae mobile phone, for the consideration to the title protection pushing resource, figure propelling movement come
The title stochastic generation of sheet, and use suffix name, resource size and partial bytes as key assignments, then can preferably avoid
During with the entitled key assignments of picture, cause the inaccurate problem of coupling because of the title stochastic generation of picture.
In the present invention one specific embodiment, also include: obtain the title of the picture downloaded；Entitled with described picture
Key assignments sets up the second caching mapping table；According to described second caching mapping table by described image cache in this locality；When receive from
When request downloaded by one picture controlling end download pictures, search whether this locality exists and treat down according to described second caching mapping table
Carry the picture of the name-matches of picture；If existing, the most directly obtain the most buffered local picture；If not existing, then from url
Extract suffix name, obtain the size of picture resource and according to described preset rules from described control according to url from described control end
End obtains the partial bytes of picture to be downloaded；Search whether this locality exists and picture to be downloaded according to described first caching mapping table
Suffix name, resource size and partial bytes coupling picture；If existing, the most directly obtain the most buffered local picture；
If not existing, then download described picture to be downloaded to the request of described control end.I.e. using Double buffer mapping table, it is right to avoid further
Picture repeat caching, and use the entitled key assignments of picture, coupling is more obvious, and the data obtained are the most directly perceived, institute
To carry out mating for scheme more preferably by the title of picture, and when name-matches does not goes up, then use the suffix of picture
Name, resource size and partial bytes are that key assignments mates.When the title preventing picture randomly selects, due to name-matches not
On, and the problem of repeated downloads picture.
In one specifically application, such as, when mobile device (control end), to OTT, (OTT is the contracting of " Over The Top "
Write, refer to provide a user with various application service by the Internet.The communication service that this application and current operator are provided
Difference, it is merely with the network of operator, and services and provided by the third party outside operator.At present, typical OTT business has
Internet television business, Fructus Mali pumilae application shop etc..) box intelligent television (local device) projection image time, first television meeting
Picture resource in CACHE DIRECTORY is built the caching mapping table that picture name is key assignments, and builds the suffix name with picture, money
Source size and the caching mapping table that partial bytes is key assignments.
When television receives projection image instruction, first according to the name lookup mapping table of picture, if the most buffered
There is this picture, then need not deduplication download again, in local cache, directly read display
If picture name does not matches, after the most remotely obtaining the resource size of picture and the picture of partial bytes and extraction
Sew name and constitute unique key assignments lookup content map table, wherein, 15 bytes that partial bytes for example, picture centre position starts
Or the uuid at picture end, if finding, local cache reads display, it is to avoid again download whole pictures resource, decreases figure
The time that sheet shows, enhance Consumer's Experience.
If two above caching mapping table does not matches, the most at this time may determine that this picture the most in the buffer, need
Download to controlling end request.
During lookup, it is the lookup of key assignments in strict accordance with content after first name, at some Dlna (DIGITAL
LIVINGNETWORK ALLIANCE, DLNA) picture name of some projection is fixing in equipment, and have
A little titles are randomly generated, and are easy to caching for the projection image that title is fixing, but for the picture of title stochastic generation,
The purpose of caching is not just reached the most again with entitled key assignments caching, if at this moment with suffix name, the resource size of picture during projection
And a combination of partial bytes makes a look up as key assignments, need repeated downloads because name matching does not go up by effectively reducing
The time of picture resource.Clearly for the when of often toggling display projection image, more preferable Consumer's Experience can be reached.
In one specifically application, the mode searching the mapping table with content as key assignments includes:
1, remotely the most not download pictures and obtain picture resource length:
Method field conventional in Http agreement has three kinds:
GET: the page info that request is specified, and return entity body.
HEAD: simply request the stem of the page.
Document specified by the acceptance of POST: request server is as the new subordinate entity to the URI identified.
Wherein, when Method is HEAD, will not go to download resource but in the Content-Length field of Http head
Return the length of resource, and respective code is 200.
2, continuous 15 bytes or the uuid at picture end that picture centre position starts is obtained:
Range header field in Http agreement can ask successfully service end with one or more subrange of request entity
The content of the position that this territory is specified will be returned, and response code is 206
3, continuous 15 bytes started in the centre position got transfer character string or the picture end of hexadecimal format to
As key assignments lookup content map table in the resource size splicing of the uuid of tail, the suffix name of picture and picture:
Form:
The resource size of Key:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-suffix name-picture
In the present invention one specific embodiment, the described step bag downloading described picture to be downloaded to the request of described control end
Include: obtain the resource size of picture to be downloaded from described control end；Judge resource size and this locality of described picture to be downloaded
Whether the resource size sum of the picture cached is more than preset capacity threshold value；The most then delete least recently used picture,
The resource size sum of the picture to have cached in the resource size of described picture to be downloaded and this locality is not more than preset capacity
During threshold value, download described picture to be downloaded from described control end；If it is not, then directly download described figure to be downloaded from described control end
Sheet；Such as, with in default 1 hour, the descending arrangement carrying out priority of number of times that picture is used, deleting successively ought
The picture that front priority level is minimum, so that spatial cache meets condition.
Or described to described control end request download described picture to be downloaded step include: from described control end obtain treat
Download pictures；Judge that the local image cache item cached is the most slow more than presetting with the cache entry sum of described picture to be downloaded
Credit balance threshold value；The most then delete least recently used picture, with the cache entry of picture that cached in this locality with under described treating
When the cache entry sum of load picture is not more than preset buffer memory item threshold value, download described picture to be downloaded from described control end；If it is not,
Then directly download described picture to be downloaded from described control end.Wherein, least recently used picture is for example, at Preset Time
The interior minimum picture operated, described Preset Time for example, 1 hour.
In a concrete application example, by http request, not download pictures resource, and obtain picture resource from far-end
Size, has exceeded maximum according to the picture resource size calculating spatial cache obtained or whether cache entry has exceeded
Big value, as beyond then least-recently-used picture being deleted release spatial cache, until spatial cache less than maximum or
Cache entry is less than maximum, it is to avoid spatial cache constantly increases, and wastes memory space.
The caching mapping table with name as key assignments is built according to the picture resource downloaded.
The character string of 15 successive bytes composition Hexadecimal form that structure starts with picture centre position or picture literary composition
Picture resource length and the caching mapping table of the entitled key assignments of suffix in uuid splicing at the end of part.
Total size of image cache and total entry are arranged for example:
Private int cacheSize=0；
Private int cacheByteSize=0；
Private final int maxCacheItemSize=64；
Private long maxCacheByteSize=1024*1024*5；//5M
When image cache size is more than 5M, or caching entry more than 64 time, the most untapped picture is deleted
Divided by release spatial cache, it is to avoid because caching causes memory space nervous.Such as, with in default 1 hour, picture is used
The descending arrangement carrying out priority of number of times, delete the minimum picture of current preference rank successively, so that spatial cache is full
Foot condition.
In the present invention one specific embodiment, also include showing the picture downloaded or obtain, and downloading or obtaining
During taking picture, currently displaying picture is gradually backed out with default animation effect, and post-set time and described picture
Download or obtain time correlation, so can alleviate the pause and transition in rhythm or melody sense caused because of the time of loaded and displayed picture, strengthen user's body
