DPI Monitor


Overview

Many cable, broadcast, satellite, and telecom operators need to insert local advertisements into digital national feeds to generate additional revenue. The SCTE 35 standard defines how to trigger these insertions automatically within an MPEG-2 transport stream. The Sencore DPI Monitor is a cost-effective  solution that continuously analyzes and logs digital cue tones. In this way, it enables local broadcasters, national networks, cable, satellite, and telco operators to maximize advertising revenue by ensuring that their infrastructures have the right in-band commands to trigger ad insertions. Robust and reliable, the DPI Monitor can analyze multiple MPEG-2 transport streams, perform comprehensive SCTE 35 logging  activities, and monitor the quality of the transport streams themselves. It also supports Web-based configuration and control as has an embedded SNMP agent for easy integration into an existing
network management system.

Continuous, Simultaneous Monitoring
The DPI Monitor continuously monitors four transport streams simultaneously. It detects programs that carry SCTE 35 digital cue tones and analyzes each advertising availability or splicing opportunity. The analysis covers availability description data including begin date, end date, duration, program identifier, and event source via a navigation interface that can look back over the last 24 hours. Additionally, SCTE 35 sections can be extracted from the most recent availability of each program.

Comprehensive Logging
By recording information about SCTE 35-related activities, the DPI Monitor can create logs that indicate the presence and occurrence of cue tones within a digital TV signal. Logs covering weeks of activity can be exported for statistical analyses to determine why a particular ad insertion failed. The monitor also features  an embedded FTP server for external applications to download these logs automatically.

MPEG Transport-Stream Monitoring
If a transport stream degrades, it can impair the transmission of SCTE 35 messages. The DPI Monitor  performs extensive operations with the transport stream protocol to ensure its quality. These operations  include TR 101 290 level 1 and level 2 testing, bit-rate monitoring, and the display of transport stream  structures.

Remote Control
The DPI Monitor can be completely configured and controlled through a Web interface. The monitor also features an embedded SNMP agent that provides SNMP traps for each availability or error detected, making it easy to integrate the monitor into a network management system.
