[0024] <Method Embodiment> Figure 1 is a flow chart of an IP-based production and broadcasting protocol detection method according to an embodiment. The implementation subject is a server.

[0025] As shown in Figure 2 , the IP-based production and broadcasting protocol detection method of the present embodiment can include the following steps S110 to S130: Step S110, receiving first stream data input by a target communication interface.

[0026] In the embodiment, the target communication interface can be an IP interface based on ST2110. The first code stream data can include at least one of video, audio, and auxiliary data.

[0027] In step S120, based on a target data type of the target to-be-tested data, a data detection configuration of second code stream data after the first code stream data is determined; wherein the first code stream data includes target to-be-tested data of the target data type.

[0028] In the embodiment, the target data type can be any one of a video stream type, an audio stream type, and an auxiliary data type.

[0029] In the embodiment, a time associated with the second code stream data is after a time associated with the first code stream data. The data detection configuration can include a constraint condition for the second code stream data.

[0030] In some embodiments, before the step S120, the method further includes steps S210 and S220 as follows: In step S210, a timestamp variation amount between time-continuous first data packets in the first code stream data is determined, and a data packet interval number between a second data packet with a set flag bit and a neighboring second data packet in the first code stream data is determined.

[0031] In the embodiment, the timestamp variation amount between the time-continuous first data packets and the data packet interval number between the second data packets with the set flag bit are determined. The set flag bit is set to 1 for the last data packet included for the to-be-tested data of the video stream type and the to-be-tested data of the auxiliary data type, and the set flag bit is set to 0 for the to-be-tested data of the audio stream type.

[0032] In step S220, in a case where the timestamp variation amount of the first data packet in the to-be-tested data meets a set step variation condition and the data packet interval number of the second data packet in the to-be-tested data is greater than or equal to a first set number, it is determined that the to-be-tested data has the data type of the video stream type.

[0033] In the embodiment, the timestamp variation amount of the first data packet meets the set step variation condition, i.e., is in a “step-like” variation, and the data packet interval number of the second data packet in the to-be-tested data is greater than or equal to the first set number, i.e., there are multiple other data packets between the two second data packets with the flag bit, so that the to-be-tested data has the data type of the video stream type, thereby determining the to-be-tested data of the video stream type. The first set number can be 2, 3, or 5, which is not limited herein.

[0034] In some embodiments, after the step S210, the method further includes step S310 as follows: Step S310, in the case that the timestamp change amount of the first data packet in the to-be-tested data meets the set step change condition and the number of data packet intervals of the second data packet in the to-be-tested data is less than or equal to the second set number, it is determined that the data type possessed by the to-be-tested data is the auxiliary data type.

[0035] In the embodiment, in the case that the timestamp change amount of the first data packet changes in a "step shape", i.e., meets the set step change condition, and the number of data packet intervals of the second data packet in the to-be-tested data is less than or equal to the second set number, i.e., there is an individual data packet between the two marker bits of the second data packet, it is determined that the data type possessed by the to-be-tested data is the auxiliary data type, so as to determine the to-be-tested data of the auxiliary data type. The second set number can be 1, 2 or 5, which is not limited herein.

[0036] In some embodiments, after the step S210, the method further includes the following step S410: Step S410, in the case that the timestamp change amount of the first data packet in the to-be-tested data meets the set smooth slope change condition and the to-be-tested data does not possess the second data packet, it is determined that the data type possessed by the to-be-tested data is the audio stream type.

[0037] In the embodiment, in the case that the timestamp change amount of the first data packet changes in a "smooth slope shape", i.e., meets the set smooth slope change condition, and the to-be-tested data does not possess the second data packet, i.e., each data packet in the to-be-tested data does not possess the marker bit, it is determined that the data type possessed by the to-be-tested data is the audio stream type, so as to determine the to-be-tested data of the audio stream type.

[0038] In some embodiments, the target data type is the video stream type; the step S120 can include the following steps S510 to S530: Step S510, acquiring the video stream basic parameters of the target to-be-tested data.

[0039] In some examples, the video sampling format of the target to-be-tested data is YCbCr, the frame / field rate is calculated based on the RTP timestamp, the ST 2110-20 header is analyzed, the field field mark is determined, whether it is an interleaved stream is determined, and the maximum value of the sampling line, the height of the frame, the sampling line offset, the length of the frame width, the frame rate, the scanning mode, the chroma sampling format, etc. are determined as the video stream basic parameters.

[0040] Step S520, determining the associated clock set by the target to-be-tested data sending object according to the video stream basic parameters.

[0041] At step S530, based on the associated clock, the data capture device of the target communication interface and the running configuration of the data capture device are configured as the data detection configuration of the second code stream data after the first code stream data.

[0042] In the embodiment, the sending object can be a sender device, a PTP master locked by the sender device is identified, and the clock of the data capture device is locked to the same PTP master as the sender device, that is, the associated clock set by the sending object of the target to-be-measured data is determined. Whether there is a non-locked capture or sender device is monitored and evaluated again, and if there is, existing adjustment measures are taken to improve the stability of the video traffic shaping parameter acquisition.

[0043] In the embodiment, based on the associated clock, the data capture device of the target communication interface is configured to capture the second code stream data at a nanosecond resolution. Using the nanosecond resolution capture function, the target traffic shaping parameter of the second code stream data can be obtained.

[0044] In some embodiments, the target data type is an audio stream type; the step S120 can include the following steps S610 to S630: At step S610, the audio stream basic parameters of the target to-be-measured data are obtained.

[0045] In some examples, the audio sampling rate is 48 kHz, the data packet time is calculated by measuring the RTP timestamp change, and the data packet size is combined according to common combinations, such as double-channel audio and 24-bit bit depth; more than three-channel audio and 16-bit bit depth, and the number of channels and bit depth are calculated as audio stream basic parameters.

[0046] At step S620, the time difference between the sending timestamp and the arrival timestamp of the target to-be-measured data is determined according to the audio stream basic parameters.

[0047] At step S630, in the case where the time difference is greater than or equal to a set difference value, a measurement window for the second code stream data after the first code stream data is configured, and a constraint condition for each data packet of the measurement window is constructed as a data detection configuration.

[0048] In the embodiment, the time difference Δt between the sending timestamp and the arrival timestamp of the target to-be-measured data is determined according to the audio stream basic parameters, and it is verified whether Δt satisfies Δt≥1ms. If the verification fails, an existing abnormal processing mechanism is triggered. The set difference value is, for example, 1ms.

[0049] In the embodiment, in the case that the time difference value is greater than or equal to the set difference value, a measurement window with a period of 200 ms is set, the first data packet of the current measurement window is determined as a reference data packet, the relative transmission time difference ΔT of the remaining data packets after each first data packet and the reference data packet is determined, and according to the constraint of the AES67 standard, the constraint condition of each data packet of the measurement window includes ΔT≤single data packet time and ΔT<17×single data packet time, so as to realize that the output audio traffic shaping parameter is a transmission stream delay factor parameter (TSDF) satisfying the constraint condition.

[0050] In some embodiments, the target data type is an auxiliary data type; the step S120 can include the following steps S710 and S720: Step S710, obtaining an auxiliary data basic parameter of the target to-be-measured data.

[0051] In the embodiment, the time stamp increment of RTP between the continuous frames of the first code stream data is determined, the rate of the target to-be-measured data is calculated according to the RTP clock frequency 90 kHz, and the auxiliary data basic parameter is obtained.

[0052] Step S720, determining a delay parameter of a protocol time stamp and an arrival time stamp of the target to-be-measured data according to the auxiliary data basic parameter, so as to obtain a data detection configuration of the second code stream data after the first code stream data.

[0053] In the embodiment, for each frame of the target to-be-measured data of the auxiliary data type, it is ensured that there is at least one or more data packets, and it is verified that the one or more data packets have the same RTP time stamp. The frame rate of the target to-be-measured data of the auxiliary data type is kept consistent with the frame rate of the video. A flag bit is set for the last data packet of each frame of the target to-be-measured data of the auxiliary data type. Each new frame of the target to-be-measured data of the auxiliary data type is recorded by the RTP time stamp increment, so as to control the delay between the data packet time and the RTP time stamp of the target to-be-measured data of the auxiliary data type to be in a moderate state, that is, the delay parameter of the protocol time stamp and the arrival time stamp of the target to-be-measured data is in a suitable range. It is ensured that the instantaneous value of the RTP time stamp of the target to-be-measured data of the auxiliary data type is not in the future, the instantaneous value of the RTP time stamp of the target to-be-measured data of the auxiliary data type is guaranteed to be no more than 1 ms in the past, unless there is a reasonable situation, the stable relationship between the RTP time stamp of the target to-be-measured data of the auxiliary data type and the PTP is maintained, and the "drift" phenomenon is avoided.

[0054] Step S130, obtaining the target traffic shaping parameter of the second code stream data according to the data detection configuration.

[0055] In the embodiment, the target traffic shaping parameter can include video stream shaping data, audio stream shaping data and auxiliary stream shaping data.

[0056] In the embodiment, after receiving the first stream data of the communication interface, the data detection configuration of the second stream data after the first stream data is determined based on the data type of the to-be-tested data in the first stream data. The target traffic shaping parameter of the second stream data can be autonomously obtained based on the data detection configuration, so as to adapt to the analysis equipment of the layered decoupling architecture, and the stability of data transmission is effectively improved.
