In this embodiment, referring to fig. 5, fig. 5 is a flowchart illustrating a live screen splash diagnosis method according to a second embodiment of the present invention. As shown in fig. 4 and 5, a target TS stream that is not the most upstream stream is selected from the plurality of TS streams, and if the target TS stream is a TS stream at an embedded point D, X bytes in a preset range of the TS stream at the embedded point D are extracted, where the preset range is a range between the latest starting position and the earliest ending position among the starting position and the ending position of each TS stream, and X is a positive integer;
matching the X bytes with other TS streams at the upstream of a target TS stream in sequence according to the reverse direction of the propagation of the live stream, namely matching with the TS stream at the buried point C, then matching with the TS stream at the buried point B, and then matching with the TS stream at the buried point A;
and when the TS stream which does not match with the X bytes is not the most upstream TS stream, taking the TS stream which does not match with the X bytes as a target TS stream, and extracting X bytes in a preset range of the target TS stream, wherein X is a positive integer. For example, if the TS stream that cannot be matched with X bytes is the TS stream at the buried point C, the TS stream at the buried point C is taken as the target TS stream, X bytes in the target TS stream are extracted, and according to the reverse direction of the live stream propagation, the X bytes are first matched with the TS stream at the buried point B, and then matched with the TS stream at the buried point a.
When the TS stream that does not match with X bytes is the most upstream TS stream, the position of the buried point corresponding to the next upstream TS stream is taken as the position where the play splash screen fault occurs, for example, when the TS stream that cannot match with the target TS stream, i.e., the TS stream at the buried point D, is the TS stream at the most upstream TS stream, i.e., the buried point a, the position of the buried point corresponding to the next upstream TS stream, i.e., the position where the play splash screen fault occurs at the local program broadcast location of the central streaming media server is determined.
When the X bytes are matched with other TS flows at the upstream of the target TS flow, whether the target TS flow is the target TS flow selected for the first time is judged, namely whether the target TS flow is the TS flow at the buried point D is judged.

Because the place where the problem occurs is not necessarily in the extracted section of X bytes, when the X bytes can be matched with other TS streams downstream of the target TS stream, the value of the X bytes is expanded, when the range of the X bytes is not more than a preset range, the step of extracting the X bytes in the preset range of the target TS stream is executed, wherein X is a positive integer, and when the range of the X bytes is more than the preset range, the live stream is determined to be fault-free.
If the target TS stream is the TS stream at the buried point C, namely the target TS stream is not the TS stream at the buried point D, the range of X bytes extracted from the TS stream at the buried point C is expanded, and when the range of the X bytes is not larger than a preset range, the step of extracting the X bytes in the preset range of the target TS stream is executed, wherein X is a positive integer. And when the range of the X bytes is larger than the preset range, executing a step of sequentially matching the X bytes with other TS flows at the downstream of the target TS flow according to the positive direction of live stream propagation.
