Design and Implementation of Live Video Analysis Information Logging Module

In real-time video delivery applications, video quality measuring systems at the end-user side have no access to the reference (uncompressed) video and thus they usually use no-reference approach when detecting artifacts in received live video and measuring its quality. Apart from live video quality analysis, in many cases additional extended post-analysis review has to be performed, in order to check existing trends related to artifacts occurrence during video streaming. Also, it can help to identify the reasons for artifacts occurrence and to prevent their future occurrence. In this paper, a design and implementation of a new tool, Live Video Analysis Logging Module (LVALM) is presented. LVALM is implemented as the new module of existing Realtime Audio and Video Artifacts Detection Tool (AVADT). It provides new functionalities in form of storing information and video recordings of artifacts detected by the AVADT. LVALM makes it possible to easily review detected artifacts at a later time, either manually or by using appropriate visualization tool.
