In step s11-s13, the network environment of monitoring medium living broadcast process substantially can be the net where monitoring terminal
Network environment, specifically can be by obtaining network bandwidth parameter, obtaining the modes such as network connection parameter come monitoring network environment；If
Network environment is normal (i.e. network bandwidth is enough, network connection is normal), then terminal can handle media according to normal code rate
Fragment simultaneously carries out normal medium living broadcast process；If network environment is abnormal, (i.e. network bandwidth is insufficient, network connection disconnects or production
Raw shake), then, in order to guarantee that normal medium living broadcast process, terminal would generally reduce the media point of abnormal moment institute plug-flow
The transmission code rate of piece come promoted the media respectively efficiency of transmission, i.e., the code of at least one media slicing of abnormal moment institute's plug-flow
Rate is lower, then, this implementation, which then needs to back up according to default code rate, to be stored in the media that this at least one media slicing is included
Hold.It is abnormal herein it should be noted that assuming that the code rate of media slicing involved in normal medium living broadcast process is 64kbps
The code rate of at least one media slicing of moment institute's plug-flow is usually less than 64kbps, and default code rate is generally greater than or equal to
64kbps.By the description of above embodiment it is found that this embodiment has only backed up the matchmaker in the case where network environment is poor
The media content of part of media fragment involved in process is broadcast live in body.
In the feasible embodiment of another kind of the invention, if optimal way is global optimization, this method exists
It is specific to execute following steps s21-s22 during executing step S102.

Hold the media content at least one media slicing；So, by the media content uploading of the backup media fragment to server it
Afterwards, the program request of identical media slicing is known in local storage space acceptance of the bid by unique identification of the server according to each media slicing
Content replaces with the media content of corresponding backup media fragment.In the feasible embodiment of another kind of the invention, if standby
Part media content is complete media file；So, after which being uploaded to server, server can be incited somebody to action
The on-demand content of on-demand media file in local storage space directly replaces with the media content of the backup media file.
In the specific implementation, this method is during executing step S103, it is specific to execute following steps s31-s33.
S31 judges whether the amount of capacity of backup media content is more than preset threshold.
S32, if not exceeded, by backup media content uploading to server, so that the server uses the backup matchmaker
On-demand content formed in medium living broadcast process described in body content update.
S33, if being more than, output upload prompting message, and receive fed back according to the upload prompting message it is upper
When passing confirmation message, by backup media content uploading to server, so that the server uses the backup media content more
On-demand content formed in the new medium living broadcast process.
In step s31-s33, preset threshold can be set according to the actual situation, such as: preset threshold can be
100KB, 500KB etc. show backup media content if the amount of capacity of backup media content is less than or equal to preset threshold
It is more short and small, transmit that occupied network flow is smaller, transmission is comparatively fast without influencing the use of terminal other function, then can lead to
Step s32 is crossed directly for backup media content uploading to server；If the amount of capacity of backup media content is more than default valve
Value, shows that backup media content is more, transmits that occupied network flow is larger, and transmission may influence terminal other function more slowly
Use, then the user of terminal side can be notified by step s33, when user confirms and uploads, then will be in backup media content
Reach server.
In the specific implementation, following steps s41-s42 can also be performed during executing step S103 in this method.
S41, during by backup media content uploading to server, if upload procedure is interrupted, record is interrupted
