    Multi-Rate Serial Digital Interface (SDI) Physical Layer IP Core Is an Ipexpress User-Configurable Core and Can Be Used to Generate Any Allowable Configuration

    ispLever TM CORECORE Multi-Rate Serial Digital Interface Physical Layer IP Core User’s Guide January 2012 ipug70_01.2 Multi-Rate Serial Data Interface Physical Layer Lattice Semiconductor IP Core User’s Guide Introduction Serial Digital Interface (SDI) is the most popular raw video link standard used in television broadcast studios and video production facilities. Field Programmable Gate Arrays (FPGAs) with SDI interface capability can be used for acquisition, mixing, storage, editing, processing and format conversion applications. Simpler applications use FPGAs to acquire SDI data from one or more standard definition (SD) or high definition (HD) sources, perform sim- ple processing and retransmit the video data in SDI format. Such applications require an SDI physical layer (PHY) interface and some basic processing blocks such as a color space converter and frame buffer. In more complex applications, the acquired video receives additional processing, such as video format conversion, filtering, scaling, graphics mixing and picture-in-picture display. FPGA devices can also be used as a bridge between SDI video sources and backplane protocols such as PCI Express or Ethernet, with or without any additional video processing. In an FPGA-based SDI solution, the physical interface portion is often the most challenging part of the solution. This is because the PHY layer includes several device-dependent components such as high speed I/Os (inputs/outputs), serializer/deserializer (SERDES), clock/data recovery, word alignment and timing signal detection logic. Video processing, on the other hand, is algorithmic and is usually achieved using proprietary algorithms developed by in-house teams. The Lattice Multi-Rate SDI PHY Intellectual Property (IP) Core is a complete SDI PHY interface that connects to the high-speed SDI serial data on one side and the formatted parallel data on the other side.

    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).

    Sdixtreme 3G+ On-The-Go Datasheet

    SDI EXTENSION - Xtreme 3G Series SDI Xtreme 3G+ On The Go SDI Xtreme 3G+ On The Go Four SDI components combined in one 3G SDI Fiber Optic Extension - Portable Unit portable unit Each module provides RS-422 port for device control - Ideal for remote camera operations requiring pan, tilt and zoom functions Each module extends SDI signals over a single "ber - Supporting two SD/HD signals or one 3G signal - Providing a total support of up to eight SD/HD or four 3G/Dual-Link SDI signals Portable unit is comprised of four modules. Any combination of transmitter/receiver is possible. SMPTE 424M, 292M, 259M, 372M, 425 level A and B compliant Auto detects input video format and displays on LEDs Thinklogcal TRANSplex module available for CWDM use Auxillary power connector for camera use 2 Ruggedized Neutrik Connectors The Logical Solution - Portable Serial Digital Interface Extension The SDI Xtreme 3G+ product series is a compact, broadcast quality, SDI over "ber extension system. The On The Go system is a portable carrying case which houses four separate SDI modules, each of which supports two SD/HD signals or one 3G signal (as well as dual-link SDI). This enables users to transmit up to eight SD/HD or four 3G SDI signals with or without embedded audio and data. Depending on the infrastructure, the SDI Xtreme 3G+ can distribute uncompressed broadcast quality signals over single mode "ber up to 40 km. (24 miles) and up to 1000 meters over multi-mode "ber. In addition, this "ber based transport system gives users the assurance that each signal is immune to video pathological signals over the entire length of the "ber interconnect, while supporting all pathological patterns at all rates.
