The complexity in the supply of television digital forces broadcasters, in-band service providers broadband and IPTV network operators to face a number of challenges in delivering high-quality content to your viewers. Network, encoding and transmission problems result in topics such as audio dubbing synchronism errors, crashing, or black screens, which in turn causes the viewers are looking for another source of content. As a result, the provider may find it difficult to identify, evaluate and solve problems in the transport flow.
A complete monitoring architecture, coupled with robust analysis and troubleshooting tools, allows a change in the quality control strategy, to go from reactive to proactive. Instead of responding to a complaint of a subscriber about the service, the service provider you can use this monitoring tool in order to perform repairs proactively, minimizing interruptions or the degradation of the signal received and seen at home. The StreamScope Enterprise Monitor (EM-40) from Triveni Digital is a service quality assurance system for the whole business complex, which proactively and in real time enables service-based response for maintenance of the integrity of transport flows throughout the whole the network.
The StreamScope EM-40 meets the needs of broadcasters, service providers and IPTV networks via monitoring a fleet of StreamScope units that continuously detect, locate, analyze and isolate faults using a set of preset rules. The same is installed in the network operations center (NOC) or others hub operations; the EM-40 monitors distributed units of StreamScope RM-40 and MT-40 in real time and automatically generates alarms when a transport flow falls outside of a configuration specified by the operator and, or, the established as desirable for the business.
Both the RM-40 and MT-40 record and measure flow rates of DTV transport in order to ensure its integrity, reliability and compliance with standards (ATSC, ATSC A/78, SCTE), providing alarms that allow quick response and troubleshooting. The RM-40 is a monitoring system Unattended remote, offering low-cost continuous monitoring of DTV transport flows. The MT-40 monitor is a complete, user-friendly instrument for analysis and verification of DTV transport flows, local or remotely. The EM-40 significantly reduces the time of unavailability to the customer and the costs of customer service claims, providing your users with analytics capabilities complete and remote of any of the monitored flows.
The EM-40 enables proactive response in real time, service-based to problems across the network, addressing four key areas of functionality: consolidation, correlation, communication and configuration. Installed in a Central location, EM-40 consolidates system data of StreamScope to provide a comprehensive view of health of service at all RM-40 and MT-40 sites.
Identification and resolution of quality problems
The industry's need to lower costs and maintain simultaneously proactive monitoring, makes monitoring centralized a critical issue for broadcasters, suppliers of IPTV service and networks with operations or stations geographically Distributed. Since it is inefficient to maintain in each site a highly qualified technician, able to solve the service failures, a NOC-based operator can use the EM-40 to obtain a consolidated view of the health of the StreamScope RM-40 and MT-40 system data service installed throughout the network, consolidating technical resources in a NOC, regional or centralized, and establishing monitoring centralized through which engineers can view status of the stations in service.
Properly located monitoring units examine the flow rates according to the correct parameters and compare them against the rules that support the entire overall strategy of the business, which is key to the proactive detection of Problems. Install monitors at all points they handle Digital signals are cost prohibitive. A better Alternative involves the permanent positioning of monitoring, such as the RM-40 or MT-40, rackmount, in strategic points and using portable equipment, such as the MT-40 portable unit, in order to reveal faults at tactical points as much as necessary.
The quality of the service can be compromised by aberrations of both audio and video, for example, video pixelation and audio dubbing synchronism errors and intermittent tuning, resulting in bit loss in the flow. Without access to flow monitoring data, you it is difficult for the provider to detect the specific cause of a problem. Packet drop, metadata errors in the PSIP and MPEG tables, PCR jitter, and buffer overflow of video, as well as the lack of provisioning of all these factors, have the potential to release non-content supervised at the time of being delivered to the TV of the customer. These types of errors can increase by a variety of points within the production chain as signals are processed, and it is often necessary to foresee and identify the problem by examining the MPEG layer in its entirety and in real time.
Instead of relying on trial and error, engineers can use the EM-40 to leverage the capabilities of monitoring the Network's StreamScope systems and analyzing the alarms and transport flow data, to make a mapping of the viewer's problems with respect to a deviation specific to applicable standards. In essence, the EM-40 provides the equivalent of an error tree. When something comes out bad with the trajectory of the distribution, the operator can use em-40 to reduce the problem area by the identification of their position within the infrastructure. Subsequently, it is possible to employ the individual systems RM-40 and MT-40, to monitor transport flows Suspects. Operators can consolidate data and perform the analysis from those sites in order to give you applicability to information about the health of the flow rates and execute the correlation between layers with the purpose to locate the identified issues. Once the monitor of flow bits identifies the problem within the flow, the Operators can isolate the device that introduced the fault.
Problems in the transport flow can be the result of several underlying factors that affect the sites to along the network. Historical and analysis tools of trends integrated into the EM-40 allow staff to engineering review and analyze past and recurring events and thus prevent them from repeating themselves in the future on the caudal.
Prioritization and problem solving
Strict monitoring of compliance with standards it can create countless alarms under conditions that, although strictly do not meet the standards, effectively do not meet the standards make a visible difference. The StreamScope RM-40 system and MT-40 uses ATSC practice A/78 to take into consideration the severity of the error and alert engineers about serious errors, such as a loss of PAT/PMT and loss of elementary video streams, while carrying audit log of fewer errors for your aftercare within the maintenance routine. The Real-time scanning of the MPEG layer enables fast scanning problem solving of serious issues, and evaluation against the preset business rules number of audio and video components, number of PSIP tables in a flow rate, and bandwidth of audio and video components, which provides an ideal template against which the flow can be validated.
Network service-based assessment is critical but very often overlooked in monitoring the quality assurance. To this end, the EM-40 provides a view of the distribution system flow topology in its entirety, which offers a representation of the health of the system, based on both site and service. The Benefit of service-based vision lies in the ability to focus technical resources on parts of the network that serve more people or a more demographically valuable audience Talking. In this way, the EM-40 offers centralized access to critical information about how well the provider is protecting key areas in revenue generation.
Conclusion
Alarms and analyses presented logically and in a way simple through the centralized and user-friendly interface of the EM-40, will be able to help in the transition to digital broadcasting of television and, consequently, to the administration of signals DTV, which is a natural proposition. Through the enabling efficient service monitoring, analysis and troubleshooting across the entire network of the both supplier in accordance with established standards and the business intent of the provider, the StreamScope EM-40 allows the operator to make a proactive approach to the ensuring the maximization of uptime, to meet viewers' expectations and preserve your revenue stream.
