Video

Video table consists of Events and Thresholds associated with the Program Video.

ID	*Name*	*Event Error*	*Description*
38	Black Frame Detection	Video Black Frame	When the content on a freeze-frame is very dark, it is a Black frame. Black frame detected for a more extended period of time than configured.
43	Detect Decoding Errors	Decoding Error	This event is triggered if there is a segmentation fault in a decoder process or unable to decode due to other reasons. Decoding errors could be caused due to errors in the content in the stream or other issues. Notification for decoder errors; may be related to transport errors or compliance problems with the encoded payload.
49	Black Frame with Logo Detection	Logo Frame	Black frame with a corner logo detected for a longer period of time than configured.
59	Freeze Frame	Freeze Frame	Freeze frame compares two frames, which may or may not be consecutive to ensure no change. Freeze frame detected for a longer period of time than configured.
60	No Video	No Video	No video on input. *If there is no input stream, there is no video or audio, and the matching events will be triggered.
84	Video Bitrate, Max Threshold	Video BR above Max	Detected video bitrate is greater than the configured maximum threshold. 1 in max threshold is equal to 101%, and 125 is equal to 225%
85	Video Bitrate, Min Threshold	Video BR below Min	The detected video bitrate is smaller than the configured minimum threshold.
116	Detect Color-Space Mismatch (ex, YUV422 instead of YUV420)	Color Space Mismatch	YUV420 is used by devices such as set-top boxes. The quality of the color is a quarter of the luminance of the video, and there is a latency between the luminance and color. For YUV422, the quality of the color is only half of that of the luminance value and has lower latency. If the received color space type does not match the configured type, the event will be triggered.
117	Detect Video Codec Profile/Level Mismatch	Video Codec Profile	Received video profile or level does not match configured values.
118	Detect Video Aspect-Ratio Mismatch	Aspect Ratio Mismatch	It's a comparison of the received error value vs. the configuration. The received aspect ratio does not match the configured ratio.
119	Detect Resolution Mismatch	Video Resolution Mismatch	The received resolution does not match the configured resolution.
123	Detect Frame Rate Mismatch	Frame Rate Mismatch	Received frame rate does not match the configured frame rate.
124	Detect Video Codec Mismatch	Video Codec Mismatch	Detected H.264 when MPEG-2 is configured or vice versa.
134	Missing SPS	SPS Missing	SPS is the sequence header and part of the payload. It provides details about the resolution and the frame. The Decoder cannot decode without SPS. Generally, SPS is sent only once for a few frames, either in a group or once in a while. If the SPS interval is greater than configured or no SPS, the event will be triggered.
172	Video Blocking Detection - Scene	Video Blocking	Video blocking measurement for multiple frames (~20) is considered as a scene event. For the scene event, the Encoder B/W issues are examined. This is a relative measurement 0-100, where 0 is the best.
173	Video Blocking Detection - Peak	Frame Blocking	The measurement for a single frame is considered as a Peak event. The artifacts and errors in the content are examined. This is a relative measurement 0-100, where 0 is the best.
229	HDR SEI data	HDR SEI	HDR is the metadata that enables higher quality of color decoding.
230	HDR SEI data missing	HDR missing	This event is triggered when HDR info is missing.
234	Video PTS variance detection	Video PTS missing	PTS is the frame rate interval. The maximum, minimum intervals and the average value is measured within a second. These three values are expected to be the same. If not, the event is triggered.
320	Missing AFD	Missing AFD	AFD defines the aspect ratio of the content. When this info is not present, the "Missing AFD" event is triggered.
321	AFD Value Change	AFD Change	Every time the file has changed, a notification with a previous value and the new value is sent.
374	Video Color Bars detected	Video Bars	Video Color Bars test signal is detected in the program.
