Quality Control System for File-Based Media - Tektronix Cerify®

Supplier: TekMark Australia

Cerify tests file-based video and audio media for Correct Encoding Syntax, Correct Encoding Parameters, and Correct Baseband and Quality Levels.

Price Guide: POA

Quality control of file-based video ingested from different sources, encoded at different bit rates / formats and utilising different compression standards for SD /HD, VOD or IPTV delivery presents considerable challenges.

Cerify, the world's first fully automated system for verifying /checking file-based content prior to transmission or use, checks for:
  • Correct Encoding Syntax: At the digital level the audio and video must be correctly encoded without errors in accordance with the compression standard, so that it plays out correctly at the customer's STB /playout device.
  • Correct Encoding Parameters: The audio and video bit rates, GOP structure, video color-space, color depth, frame size, frame rate, aspect ratio, and quantization levels must be correct.
  • Correct Baseband and Quality Levels: The analog parameters of signal levels, luma, chroma, gamut, and quality levels of black frames, video quality (blockiness), loss of audio, audio clipping, and video and audio playtime.
