Enhancing Videoconferencing Test Methodologies through VQEG Validation Project

The VQEG has previously validated videoconferencing (VC) materials using traditional TV testing methods. While existing interactive methods like P.920 are available, they require significant updating. There are concerns regarding the validity of current VC data. To address this, a new VQEG project focuses on videoconferencing, aiming to collect data that enhances subjective test methodologies. The project emphasizes the need for tests that accurately reflect various VC scenarios, including coding, transmission, and display conditions, ensuring comprehensive validation.

Presentation Transcript

  1. Videoconferencing Project • VQEG has validated VC material in previous tests • These were based on standard TV test methods • Existing interactive methods exist (P.920) • But this is dated and requires updating / improving • Furthermore, objective models have been validated across content types • Question mark over whether the VC data is valid

  2. Proposal • New VQEG project dedicated to VC • VQEG participants provide data to improve subjective test methodology • Verified method applied to perform validation tests • Tests should be representative of VC scenarios and coding/transmission/display conditions
