S304, the first feedback information sent according to client, adjust compression algorithm.

Specifically, the first feedback information sent according to client, adjustment service end is compressed processing to view data When the compression algorithm that uses.Wherein, the first feedback information includes：First decoding speed.Exemplary, as shown in figure 4, adjusting Journey mainly includes：

S3041, according to the first decoding speed, retrieve known client algorithm table, and client is classified.

Specifically, known client algorithm table is default description known compression algorithms, known client type in service end With the corresponding table of decoding speed scope corresponding relation, it can be realized in the form of an algorithm in service end；The known client algorithm Table indicates each known compression algorithms and existed including containing a variety of different known compression algorithms including the first compression algorithm Corresponding decoding speed scope and the corresponding optimal pressure of each known client type under different known client types Compression algorithm.

It is worth mentioning, it is known that the corresponding optimal compression algorithm of known client type recorded in client algorithm table is For the characteristic of different clients type, the compression algorithm of setting is pre-selected, as a rule, is calculated using the optimal compression Method can make the decoding speed of client reach predetermined requirement；Different known client types can be different for hardware condition Client, or the client that hardware condition is identical but operating system is different.It can also include in the first feedback information The OS Type of client, can be by searching the operating system that known client type is marked in known client algorithm table Type information, auxiliary efficiently determines the classification of client.

Known client algorithm table is retrieved, if the first decoding speed falls the first compression algorithm in known client algorithm table Under in the range of a corresponding decoding speed, then be known classification by client-classification.

Or, if the first decoding speed is not in the range of any one corresponding decoding speed of the first compression algorithm, by visitor Family end is categorized as unknown classification.

S3042, the classification according to client, select corresponding adjustable strategies.

If specifically, being known classification by client-classification, selecting to be adjusted using the first adjustable strategies, performing S3043；Or, if being unknown classification by client-classification, select to be adjusted using the second adjustable strategies, perform S3044.

Known client algorithm table is retrieved again, judges whether the second decoding speed is more than default decoding speed threshold value, its In, default decoding speed threshold value is targeted compression algorithm in known client algorithm table under the type of the known classification client Corresponding decoding speed lower range limit.

If so, then service end is selected carries out the processing of subsequent image data using targeted compression algorithm, and terminate adjustment；Or Person, if it is not, client then is re-classified as into unknown classification, and selects to be adjusted using the second adjustable strategies, performs S3044。

S3044, the second adjustable strategies of execution are adjusted.

Specifically, retrieval known client algorithm table, obtains Optimize Compression Algorithm；

Exemplary, obtaining Optimize Compression Algorithm includes：
