The Mividi IMS120 provides a comprehensive solution for broadcast video monitoring. It combines multiviewer monitoring, comprehensive MPEG transport stream analysis, error logging and alarms, and TS recording in a single standard Windows computer.

Broadcast TV Multiviewer Monitor

Comprehensive Broadcast Monitoring in a Single System

The Mividi IMS120 is a broadcast transport stream monitoring system for viewing video and audio services, analyzing transport streams, logging errors, generating alarms, and recording stream. The IMS120 was developed to automate monitoring and error diagnosis at digital head-ends for broadcasters, MSOs, Telcos and online streaming video providers. It is a single Windows based system that can complete tasks previously done by several different pieces of equipment. It will pay for itself in manpower savings over a short period of time.

The Mividi IMS120 can be used for monitoring DVB and ATSC broadcast streams, as well as online media using various online streaming protocols. It supports MPEG-2, MPEG-4, AVC (H.264), and HEVC (H.265) video compression formats, as well as commonly used audio formats.

The system provides a real time multiviewer display of video or audio services coming from different input interfaces including IP and DVB ASI. It can simultaneously display up to 60 SD video or 30 HD video programs, analyze and record the streams. Any transport stream errors are logged in a database for review and reporting. Users can select alarms to be triggered by certain errors.

The monitoring system is built on standard PC or servers using Windows 7, 10 or Windows Server 2008, 2012, 2016. Mividi supplies fully-built systems or software which can be installed on customers’ own hardware. An optional web server can be used to connect to multiple monitoring servers in different locations to access test results and control these servers remotely.

Multiviewer Monitoring

The IMS120 supports multiviewer display of videos and audio volume bars from SPTS and MPTS inputs. It also calculates audio loudness and displays the loudness value along with video images. Additionally, the system can decode and display DVB subtitles and ATSC closed captioning data.

Each monitoring system can support up to four monitoring panels for multi-image display using graphic card features. The display panels can be configured in terms of size and location. Audio-only program display is also supported.

Support Compressed and Uncompressed Video

The IMS120 supports both compressed and uncompressed video streams. The software decoder supports compressed video in MPEG-2, H.264, H.265, VC-1, and most common audio encoding formats including MP3, AAC, AAC+, Dolby AC3. It supports physical interfaces including IP and DVB ASI and many different streaming protocols, including MPEG transport streams, HLS, TS over HTTP, MPEG-DASH, RTMP, RTSP, and MMS.

Uncompressed video in SDI or HDMI format can be received using one or more BlackMagic Decklink cards and directly displayed on Picture-in-Picture (PIP) panels.

MPEG TS Analysis; DVB Monitoring; ATSC Monitoring

Comprehensive TS Analysis

The Mividi IMS120 provides comprehensive TS analysis for both DVB and ATSC streams. The system performs detailed TS error checks based on DVB test guideline TR 101 290 and reports all three priority level errors. It analyzes transport stream program structure, measures PID bitrate, performs PCR, and buffer analysis. It decodes key frames and detects any black frames and frame freeze.

In addition to MPEG transport layer testing, the system also performs IP and HTTP layer testing. It measures delay factor and media loss rate on IP streams and monitors and logs detailed HTTP session and downloading parameters on HTTP and HLS input streams.

The TS analysis features provide a very useful tool for trouble-shooting transport stream issues.

Error Logs and Alarms

The system provides multiple ways of sending error alarms, including email, visual displays on a multiviewer screen, and audio sound. The alarms can be triggered by errors selected by users, such as loss of input, audio or video components, black or frozen frames, etc.

All errors and alarms are logged in the database and can be reviewed at a later time. Reports can be generated to summarize TS status over a period of time.

Transport Stream Recording

The system can be used to record full transport streams or selected programs. Both auto-recording and manual recording are supported. A remote user interface for managing recorded files is also provided for playing recorded files, searching specific recordings, and cleaning the hard disks. Additionally, the system may be linked to a file storage server in order to support high bandwidth data recording.

Remote Access

The TS analysis, error logging, alarm configuration, and TS recording UI applications can all be run on remote computers for remote access to the testing data. In addition, an optional web server can be used to link multiple monitoring servers in different locations for single point data access and system management. The web server can be accessed using a standard web browser, and it is an ideal choice for network-wide video service monitoring.

The system provides multiple ways of viewing the conditions of video services remotely. Video key frames are decoded and may be displayed in a remote monitor. Additionally, the full multiviewer display screen can be captured and streamed to a remote location for display.
