in step 10, performing name similarity matching by using the channel name specifically includes:
if a server channel with the same name as the channel uploaded by the client is searched, acquiring the channel with the same name; if the server channel with the same channel name as the channel name uploaded by the client is not searched, the similarity between the client channel name and the server channel name is calculated, and the server channel with the name similarity larger than a set value (the set value can be set according to the accuracy of the server channel data, for example, set to be 0.8) is obtained.
Step 20, country matching process: taking the second result, the first result or the third result as a first matching set according to the priority (namely, the second result is taken preferentially, if the second result is empty, the first result is taken, if the first result is empty, the third result is taken), then carrying out country matching according to the country where the client is located and the country of issuance of the channel in the first matching set, and recording the matching result with the same country as the fourth result;
acquiring the number of records in the fourth result;
if the record number of the fourth result is 1, taking the record as a final matching result;
if the record number of the fourth result is not 1, go to step 30;
step 30, language matching process: taking the fourth result, the second result, the first result or the third result as a second matching set according to the priority (namely, the second result is taken preferentially, the first result is taken if the second result is empty, and the third result is taken if the first result is empty), performing language matching according to the language set by the client and the language attribute of the channels in the second matching set, and recording the matching result with the same language as the fifth result;
acquiring the number of records in the fifth result;
if the record number of the fifth result is 1, taking the record as a final matching result;
if the number of records of the fifth result is not 1, go to step 40;
step 40, similarity matching process: taking a fifth result, a fourth result, a second result, a first result or a third result as a third matching set according to the priority order (namely, taking the fifth result preferentially, taking the fourth result if the fifth result is empty, taking the second result if the fourth result is empty, taking the first result if the second result is empty, and taking the third result if the first result is empty), and obtaining at least one record with the highest similarity of the channel names in the third matching set as a sixth result;

In a specific embodiment, the server channel list in the sixth result is sequentially traversed, if the channel status attribute value is 1, which indicates that the channel has an EPG program (the server will update the channel and the program corresponding to the channel from the data provider at regular time, if the channel has an updated program, the channel status attribute will be set to 1), the channel is stored in the result, and the matched result is recorded as the seventh result.
The three-code information is a channel triple group, which is composed of three groups of numbers from 0 to 65535 and identifies a unique channel, but because the number of channels at the client is recorded in hundred million, and the channels are highly integrated by the server and are summarized into ten thousand-level channels, the result searched by the three-code information and the channel name is not necessarily a unique result, and the accuracy and the integrity of the channel matching result are improved by multi-dimensional matching and high-flexibility matching.
