  • Page 5: Module Overview

    Model 7435 and 9455 Clean and Quiet Protection Switches Module Overview The 9455 and 7435 modules are clean and quiet protection switches for critical broadcast and satellite feeds. They switch cleanly between asynchronous sources which means they can be used live to air. Each module has a full video frame synchronizer, rather than a line delay, ensuring perfect alignment of mis-timed and non-synchronous SDI sources.

AES/EBU or AES3 describes a serial bitstream that carries two audio channels, thus an AES stream is a stereo pair.
  • Page 56 Model 7435 and 9455 Clean and Quiet Protection Switches Systems that operate with a greater number of bits of resolution, or quantization, will be able to capture a signal with more detail or delity. Thus, a video digitizer with 12 bits of resolution will capture 4 times as much detail as one with 10 bits.

  • Page 58: Embedded Audio

    Model 7435 and 9455 Clean and Quiet Protection Switches Embedded Audio Digital Audio can be carried along in the same bitstream as an SDI or HD-SDI signal by taking advantage of the gaps in the transmission which correspond to the horizontal and vertical intervals of the television waveform.
  • Page 59 Model 7435 and 9455 Clean and Quiet Protection Switches sources. It is an uncompressed, all-digital interface that transmits digital video and eight channels of digital audio. HDMI is a bit serial interface that carries the video content in digital component form over multiple twisted-pairs.
  • Page 60 Model 7435 and 9455 Clean and Quiet Protection Switches Luminance The “black & white” content of the image. Human vision had more acuity in luminance, so television systems generally devote more bandwidth to the luminance content. In component systems, the luminance is referred to as Y.

Copper is barely useful at distances of just 1000 feet. Oversampling A technique to perform digital sampling at a multiple of the required sample rate.

  • Page 62: Single Mode

    Model 7435 and 9455 Clean and Quiet Protection Switches Setup In the NTSC Analog Composite standard, the term Setup refers to the addition of an arti cial o set or pedestal to the luminance content. This places the Black Level of the analog signal 54 mV (7.5 IRE) positive with respect to ground.
  • Page 63 Model 7435 and 9455 Clean and Quiet Protection Switches is used to read the video back out of the memory. The memory acts as a dynamically adjusting delay to smooth out the imperfections in the original signal’s timing. Very often a TBC will also function as a Frame Synchronizer.
  • Page 64 Model 7435 and 9455 Clean and Quiet Protection Switches for every bit in the digital audio word. A clock signal, which is a square wave at the audio sampling frequency, is carried on a 75 ohm coaxial cable. Early systems would daisychain this 44.1 or 48 kilohertz clock from one device to another with coax cable and Tee connectors.
