Elecard SenSay
Video streams quality monitoring service
Elecard SenSay is a multifunctional service designed for quality control of the video streams which perfectly serves OTT and IPTV broadcasting, DVB content preparation and video surveillance systems
Analyzed parameters
• Signal loss
• Stream packets loss (cc errors)
• Clock Continuity (incorrect timestamps sequence)
• Stream headers
• Quality level of the encoded video-stream
• Payload rate
• Thumbnails
• Digital Program Insertion Cueing Message
How it works
1. Elecard SenSay is a software product (client-server application) consisting of 2 parts: software SenSay probe and cloud-based SenSay server designed to collect and process statistics.

2. Software SenSay probes are distributed over the network and transfer video specific data to SenSay server; cloud-based SenSay server receives, analyzes and aggregates the statistical data provided by SenSay probes.

3. Elecard SenSay operates under Windows, Windows Server, Linux (Unix).

4. Elecard SenSay ensures fast email and/or sms notification and localization of most common violations in video content delivery.

  • Software SenSay probe is set up at the head-end station, at input streams monitoring points and after transcoding, multiplexing and encrypting modules. Additional locations might include end-points of main delivery networks, signal distribution points and last mile locations.
  • The user starts the probe in the monitoring point. Tasks for analysis are assigned to the probe in the dashboard of the SenSay service. SenSay probe detects violations in the stream and transfers the detailed statistical information to Elecard SenSay server. The server aggregates the received data and provides reports in easy-to-understand graphic form for each segment of the network in the web browser.
  • Service provides fast and cost-effective monitoring of content delivery networks by registering the following parameters: violations and parameters of transport stream layer (СС, ETSI TR 101 290 (Priority 1), bitrate parameters), signal loss, video freeze, EPSNR, etc. Estimated PSNR (Estimated or No-Reference PSNR) is the metric that measures typical PSNR values of the encoded video sequence without the reference video sequence.

Continuity Counter
ETSI TR 101 290 First priority 1.4 Continuity_count_error. Incorrect packet order or a packet occurs more than twice or lost packet.
EPSNR
EPSNR – is a graph representing the statistical evaluation of the ratio distortion of digital video data in the process of encoding. PSNR is measured in terms of the decibel scale and is determined as an attitude of peak quadratic value of the video signal to the quadratic deviation of the decoded image to the original/source image. EPSNR (Estimated Peak Signal to Noise Ratio) is estimated based on data contained in the encoded video stream and does not require reference (uncoded) video images.
Clock Continuity
PTS/DTS timestamps continuity, incorrect sequence detection. Equivalent to ETSI TR 101 290 Second priority 2.5 PTS_error. PTS repetition period more than 1000 ms.
RTP over UDP (multicast). The stream should meet the RTP Payload Format for MPEG1/MPEG2 Video (rfc2250) specification.
