Simultaneous, Remote Multipoint Monitoring    Real Time Monitoring and Drill Down Analysis    Comprehensive Stream Examination Simultaneous, Remote Multipoint Monitoring Fleet Monitoring StreamScope™ monitors and analyzes the entire DTV infrastructure from any or all locations. Each StreamScope in the monitoring fleet is capable of monitoring all of its inputs simultaneously. The monitoring and analysis results are displayed within a client User Interface, either run on the StreamScope unit itself, run remotely with a network connection to the StreamScope unit. The client User Interface also connects to multiple StreamScopes, where the monitoring results are collated and displayed within a single, unified view. Flexible Inputs StreamScope is capable of monitoring different types of physical transports within a DTV plant, as well as those encountered in the field. VSB and 64/256 QAM inputs allow for monitoring the signal that leaves the DTV plant. DVB-ASI, SMPTE-310 and Gigabit Ethernet inputs provide monitoring capabilities for signals within the DTV plant. The Gigabit Ethernet input enables capture and in-depth analysis of transport within the IP stream, as well as play-out of a pre- recorded transport. Recording and Playback Easy-to-use button-controls support manual recording and play back of transport streams for display or analysis. Standard MPEG-2 file format achieves compatibility with a variety of other servers, players, and analyzers. Click to zoom! Top Real Time Monitoring and Drill Down Analysis Detailed Monitoring Information - at a Glance StreamScope's Monitor Window presents detailed status of the transport stream, reported in real-time. The convenient Stream Status Tree enables drill-down to various specific stream properties. The screen displays • The virtual channels, elementary streams, and PIDs in a transport stream • Errors where a stream property does not comply with the standards • Which of the stream properties exceed any of the many user-defined thresholds • Bit rate and percentages of audio, video, data, and null packets in the entire stream, by program, or by packet identifier (PID) Click to zoom! PSIP & MPEG-2 Tables The transmission intervals of ATSC PSIP & MPEG-2 system tables are shown. The complete contents of the tables using semantic labels in an easy-to-understand format are also displayed. Click to zoom! Video & Audio Buffer Graphs The audio and video buffer usage graphs (video buffer shown above) help determine cause of buffer overruns and underruns. Click to zoom! PCR Timing Information A detailed graph is produced of PCR jitter indicating the jitter amounts detected (blue bars) and the limits allowed in the ATSC standards (red lines). Click to zoom! Triggered Recording & Alarms Any error condition or user-defined threshold can be used to trigger recording or optional alarm relays integrated with station monitoring equipment. Video and Audio Monitoring All ATSC, SCTE & DVB video formats are decoded and displayed. Available programs & their video/audio PIDs are automatically discovered. Video output format : SVGA Audio output format : Stereo Top Comprehensive Stream Examination Summary Window Summary Window allows you to spot the source of transport stream errors at a glance, and displays the composition of MPEG-2 programs in the stream. MPEG-2 Program Summary The MPEG-2 Program Summary shows an overview of the MPEG-2 programs in the stream, including: • Video and audio PIDs • SCTE 35 Cue Tone PIDs • Bit rates for each PID • Indication of buffer over/underflow • Indication of PCR jitter/offset Click to zoom! Transport Stream Status The Transport Stream Status lists 13 types of potential transport stream problems, when they last occurred, and how often. Even without detailed knowledge of MPEG-2, ATSC, or SCTE standards, you can identify the problem and communicate it to engineers or equipment vendors. With advanced knowledge, you can drill-down further using the Monitor Stream window to analyze the cause. Cross-Table Consistency Analysis The CTA view analyzes the contents of PSIP and MPEG-2 PSI tables in a stream, to ensure they are consistent with each other. These metadata tables provide information to DTV receivers on decoding the stream. They contain a complex system of references to each other and to the programs in the stream. Inconsistencies could impair tuning or appearances of onscreen Electronic Program Guides (EPGs) • Finds conflicts and data errors, displaying them "at a glance" • Makes you a PSIP and MPEG-2 expert in seconds with its easy-to-use display • Produces reports that you can print or save to file • Shows a simulated EPG from the PSIP data in the stream Click to zoom!
