Abstract

Disclosed herein are systems and methods for causing a stunt switcher to run a multi-video-source digital-video effect (DVE). An example method involves (i) selecting a first log-entry from a traffic log, wherein the first log-entry corresponds to a first video-component (VC) and a first start-time; (ii) selecting a second log-entry from the traffic log, wherein the second log-entry corresponds to a multi-video-source DVE, and a second start-time; (iii) causing the first VC to start being channeled through the stunt switcher proximate the first start-time; (iv) making a determination that a threshold time-period remains before the second start-time; and (v) responsive to making the determination, (a) causing a second VC to start being sent to the stunt switcher, and (b) causing the stunt switcher to run the multi-video-source DVE, thereby causing the stunt switcher to output a combined video, wherein the combined video includes the first VC and the second VC.

5. The method of claim 1, wherein the second log entry is the next log entry after the first log entry.

6. The method of claim 1, wherein the second log entry includes the second start time represented as a calculated start time.

7. The method of claim 1, wherein the second log entry includes a house identifier field and an identifier stored in the house identifier field, wherein the identifier maps to a set of program instructions that when executed cause performance of the functions of (i) making the determination that the threshold time period remains before the second start time, and (ii) responsive to making the determination that the threshold time period remains before the second start time, (a) causing the second VC to start being channeled through the stunt switcher, and (b) causing the stunt switcher to run the stored multi-video-source DVE, thereby causing the stunt switcher to output the combined video;

and wherein the method further comprises responsive to determining that the second log entry includes the identifier, executing the set of program instructions.

8. The method of claim 7, wherein the set of program instructions comprises a set of PHP Hypertext Preprocessor (PHP) scripts.

9. The method of claim 1, wherein the determination is a first determination, the method further comprising:

making a second determination that the second VC has ended; and

responsive to making the second determination that the second VC has ended, causing the stunt switcher to run a DVE, thereby causing only the first VC to be channeled through the stunt switcher.

10. The method of claim 1, further comprising:

adding an indication that the second VC has been broadcast to an as run log.

11. The method of claim 1, wherein the master control system comprises the stunt switcher.
