Description
Technical field
The present invention relates to network technique fields, more particularly to a kind of method, system and the device of online synthesis subtitle.
Background technique
With the continuous development of network and direct seeding technique, more and more people take to live streaming industry, in order to make to be broadcast live
With better effect, it usually needs subtitle is added on the screen, in subtitle synthesis process, due to parsing and rendering subtitle text
Part needs to carry out a large amount of operation, can occupy more hardware resource in this way, so in traditional live streaming, usually using special
Caption machine add subtitle, but certainly will increase the input cost and learning cost of live streaming in this way, be unfavorable for the popularization of live streaming；
Live streaming end carry out subtitle synthesis, then to live streaming end hardware performance requirements it is higher, and synthetic effect by live streaming end influenced compared with
Greatly, cause synthetic effect irregular, the subtitle effect that platform is broadcast live is made to be difficult to obtain unification, be unfavorable for that pushing away for platform is broadcast live
Extensively, so needing a kind of inexpensive and stable synthetic effect subtitle synthetic method in the market.
Summary of the invention
It is an object of the invention to propose method, system and the device of a kind of online synthesis subtitle, to solve the above problems.
To achieve this purpose, the present invention adopts the following technical scheme:
A kind of method of online synthesis subtitle, including server, are broadcast live end and client, the live streaming end and the service
Device, by being connected to the network, stores subtitle material in the server by network connection, the client and the server
Library；It the described method comprises the following steps:
Step 1, live streaming end sends setting subtitle instructions to server, and server extracts partial words from subtitle material database

It connects, stores subtitle material database in the server 2；As shown in Fig. 2, the described method comprises the following steps:
Step 1, live streaming end 1 sends setting subtitle instructions to server 2, and server 2 extracts portion from subtitle material database
Divide subtitle material and is sent to live streaming end 1；
Step 2, live streaming end 1 receives subtitle material, and is shown as the example of multiple subtitle materials；
Step 3, a subtitle material is selected at live streaming end 1, end 1 is then broadcast live and sends the subtitle material or its number
To server 2；
Step 4, server 2 receives live streaming end 1 and issues subtitle material or subtitle material number, then by the subtitle element
Material is synthesized to the top of live streaming picture, and sends live streaming end 1 for the live streaming picture after synthesis；
Step 5, after live streaming end 1 receives live streaming picture, the effect of subtitle synthesis is shown on the screen；
Step 6, it re-execute the steps subtitle material selected by 3 or confirmation and carries out step 7；
Step 7, caption content is edited, and sends server 2 for caption content；
Step 8, server 2 receives caption content, then synthesizes caption content according to the format of selected subtitle material
To the top of live streaming picture, then the live content after synthesizing subtitle is separately sent to live streaming end 1 and client 3 by server 2；
Step 9, picture is broadcast live in live streaming 1 real-time display of end, and live streaming position and angle are adjusted according to live streaming picture；Client
End 3 receives and shows live content.
The calculating process of entire subtitle synthesis is all completed in server 2, and live streaming end 1 only needs to select subtitle material, input
Caption content and display subtitle synthetic effect, can effectively reduce the hardware-dependent to live streaming end 1, cloud computing is made full use of to provide
Source, compared to using caption machine to carry out subtitle synthesis, 90% can be reduced by being broadcast live using online subtitle synthetic method
Cost is very suitable for civil live streaming；And subtitle material lab setting is beyond the clouds, it is possible to reduce the EMS memory occupation at live streaming end 1, and
Also facilitate and material database is updated.
As shown in figure 3, the live streaming picture at the live streaming end 1 is divided into multiple regions, the subtitle material is according to belonging to it
Classify in region；
In the step 1, need to be arranged the region of subtitle in the selection of live streaming end 1, end 1 then is broadcast live will be in the region
The instruction of setting subtitle be sent to server 2；Server 2 receives described instruction, and institute is then extracted from subtitle material database
The subtitle material in region is stated, then sends live streaming end 1 for the subtitle material.
