At present, live broadcast program index alarms are mainly divided into code stream layer alarms and picture layer alarms, aiming at the code stream layer alarms, when the related physical indexes reach or exceed a threshold value, a change-over switch of a signal switching system can automatically switch without manual intervention, but when the code stream layer is normal, and picture layer abnormal alarms with stronger subjective judgment such as black fields, static frames, silence, color bars, color fields, mosaics, decoding abnormality and the like occur, the signal switching system does not generate actions, and manual intervention is needed, namely, a person on duty is required to manually search the change-over switch and then switch operation is implemented.
According to daily duty data statistics, when a single live program fails, the whole process is required to be switched successfully from fault finding and switching switch searching, the shortest time is required to be 20 seconds, the longest time is required to be 50 seconds, when a plurality of live programs fail simultaneously, the longest time is increased along with the live programs multiplied by 15 seconds, the whole process can also have the conditions of errors caused by manual searching and searching, and the like, and under the safe broadcasting assessment system taking minutes and seconds as a calculation unit, the method has high requirements on duty personnel.
Taking an average of 180 sets of live programs (IPTV platform) and 48 frequency points (DVB platform) as an example, the number of signal switches is already more than 200, and the number of the signal switches is further increased along with the increase of the number of the live programs. In the face of increasingly severe safety broadcasting supervision requirements, how to quickly and accurately find out signal switching switches corresponding to alarm programs and quickly treat the signal switching switches in switching switch pages of a plurality of pages in full screen, and the method provides great challenges for psychological quality, skill level and attention of operators on duty.

the message distribution server screens out alarm types to be treated according to preset conditions, and then pushes the screened alarm information to the information source switching server;
the information source switching server analyzes the received alarm information, extracts keywords and matches the keywords of the pre-stored program switching switches, and if the keywords are consistent, the corresponding switching switches are color-marked and set to be top in the switching switch page.
The invention has the beneficial effects that:
1. the invention provides a live broadcast signal picture layer alarm linkage processing method and system through alarm monitoring, message distribution and information source switching program modules, when live broadcast signals generate picture layer alarms, the switch of corresponding programs can be marked and set on top rapidly, the switching efficiency of information sources can be effectively improved, the user experience is improved, the working pressure of operators on duty is reduced, and meanwhile, the occurrence of safe broadcasting accidents is avoided.
2. Aiming at different program signal types, the information source change-over switch is associated with different keywords, and the multicast type program selects program stream IP (multicast IP) and the radio frequency type program selects frequency so that the system can be adapted to a traditional DVB live broadcast platform of a broadcast television and an emerging IPTV live broadcast platform.
