    Designed to Perform NEW The 8 Channel Server Production & Media Server Designed to Perform More Power. More Channels. More Capabilities. The new generation of XT servers, with its flexible 8 channel SD/HD & 6 channel 3D/1080p configuration, combines EVS’ world-class speed & reliability with the ultimate capabilities and performance. XT3 integrates today’s top broadcast and IT technologies to offer broadcasters and producers unparalleled motion control and adaptability. Based on its unique Loop Recording technology and its powerful networking capabilities, XT3 offers operators complete media control from ingest to playout, including live editing, slow-motion replays, multi-channels playback, and transfer to third-party systems such as craft editors, automation, archiving, or storage. The XT3 is the first server to natively support such a wide range of codecs without requiring hardware changes, allowing production teams to easily choose amongst the different compression schemes they want to use throughout the entire edit process. Designed to boost broadcasters’ live and near-live production capabilities, the XT3 provides operators with the highest level of bandwidth, flexibility and control available in the industry today.

  • 1. Introduction
    AN377 TIMING AND SYNCHRONIZATION IN BROADCAST VIDEO 1. Introduction Digitization of video signals has been common practice in broadcast video for many years. Early digital video was commonly encoded on a 10-bit parallel bus, but as higher processing speeds became practical, a serial form of the digitized video signal called the Serial Digital Interface (SDI) was developed and standardized. Serialization of the digital video stream greatly facilitates its distribution within a professional broadcast studio. Master Sync Generator Sync Video Server (Mass Storage) (Genlock) On-site Video Cameras SDI SDI Video Switching/ Processing SDI Transmission Facility SDI SDI Distribution Video Amplifier SDI SDI Router Frame Synchronizer SDI SDI Remote Professional Video Server Video Camera Monitor (Storage) Figure 1. Typical Example of a Professional Broadcast Video In a studio with multiple cameras, it is important that video signals coming from multiple sources are frame aligned or synchronized to allow seamless switching between video sources. For this reason, a synchronization signal is often distributed to all video sources using a master synchronization generator as shown in Figure 1. This allows video switching equipment to select between multiple sources without having to buffer and re-synchronize all of its input video signals. In this application note, we will take a closer look at the various components that make up a broadcast video system and how each of the components play a role in the synchronization chain. Rev. 0.1 8/09 Copyright © 2009 by Silicon Laboratories AN377 AN377 2. Digitizing the Video Signal A video camera uses sensors to capture and convert light to electrical signals that represent the three primary colors– red, green, and blue (RGB).

  • Aspen 3232HD-3G 32X32 3G HD−SDI Router
    Aspen 3232HD-3G 32x32 3G HD−SDI Router The Aspen series routers are high−performance matrix switcher for 3G HD−SDI and HD−SDI dual link video signals. These units can switch any or all inputs to any or all outputs. Aspen 3232HD-3G HD-SDI Video Features Guaranteed 3G Bandwidth - Fully Loaded. Max Data Rate - 2.97Gbps. Multi-Standard Operation - SDI (SMPTE 259M & SMPTE 344M), HD−SDI (SMPTE 292M), 3G HD−SDI (SMPTE 424M) and dual link HD−SDI (SMPTE 372M). Advanced Equalization - Allows recovery of signals at over 155 meters at 3Gb/s, over 200 meters at 1.5Gb/s Reclocking & EQ Control - Reclockers and Equalizers can be turned on or off on a per port basis to allow non- SMPTE data such as MPEG-2 to pass through. - Input Equalization - Per input. - Re-Clocking - 5 modes: auto, bypass, 3G HD-SDI, HD-SDI & SD per input. Sync Features Looping Sync Input - Composite or Tri-sync. Control Features Front Panel XY Control (1616/3232HD-3G) - Multi-color I/O & function buttons. Built-in Web Control Interface - - Configuration and Set up - including Names, Salvos, Layers, Output Reclockers, Input Equalizers and more. - Touch and Click compatible for control via tablets or smartphones RS-232, RS-422 & Ethernet. Optional Remote Control Panels - Via RJ-45 (Ethernet). Supports TCP/IP Protocol - Rear Panel RJ-45 connector. Other Features 7 Year warranty - Parts and Labor Take - The Take button executes a selected function when pressed (switch, salvo recall, IP address change, etc.). Salvos - Memory locations of switching lists that are saved in the router and recalled by a single command.
