Professional Real-time HTTP Live Streaming (HLS) Analyzer for validating HLS formats, verifying standard compliance of stream segments, and monitoring service errors. It is suitable for service providers to test HLS video service infrastructure and monitor OTT video service quality (QoS).
A single server can simultaneously monitor up to 300 HLS streams. It provides auto-alarm, error logging and report generation functions.

As smartphones and tablets are getting more popular, more TV programs are consumed by these devices. Content providers estimate as much as 75% of video contents will be watched on devices other than TV sets in the next few years. The most commonly used methods for delivering video services to mobile devices and computers are various media streaming protocols, including RTMP, RTCP, HTTP Live Streaming, and MPEG-DASH via the Internet.
HTTP Live Streaming (HLS) is an HTTP-based media streaming protocol implemented by Apple Inc. It breaks the overall stream into a sequence of small files, each containing one short chunk of an overall finite or unbounded transport stream. The client app downloads the files using HTTP protocol and reassembles the files into a continuous transport stream. Since the downloading uses only standard HTTP transactions, HLS is capable of traversing any firewall or proxy server that lets through standard HTTP traffic, unlike UDP-based protocols such as MPEG over UDP or RTP.
However, using IP networks to transport media data can introduce transmission errors such as delay, jitter and packet loss. Video delivered over the Internet over which the video provider does not have full control can exacerbate the problem. On the other hand, video transport has strict requirements on the timely delivery of the video and audio packets to the receivers. Therefore, it is important for service providers to actively test their media service infrastructure and monitor services real-time to discover and resolve any potential problems quickly.
The Mividi HLS Analyzer is designed to verify the quality of digital audio and video services delivered using the HLS protocol. The system can simultaneously start hundreds of HTTP sessions to download audio and video data from one or more video servers, and perform extensive analysis on HTTP transfer status, HLS file formats, MPEG TS standard compliance, and audio and video quality in all video services.
The system is designed for 24 x 7 remote operations. All errors detected by the system are saved in the database, along with transport stream snapshots and HTTP downloading statistics. Multiple reports can be generated to summarize the HTTP session and transport stream status over time.
