N16255, Verification test report for Internet Video Coding

~~This document reports the results of a formal subjective test. The test compared the current state of the draft IVC reference software encoder against a reference software encoder for the AVC High Profile (based on AVC HP bitstreams that were previously provided in contributions from January 2014, at which time some previous testing was conducted). Encoding configurations for “random access” and “low delay” use cases were tested, with video test sequences of three resolutions – 832×480 “WVGA”, 1280×720 “720p” and 1920×1080 “HD”. The specific encoder versions and their configurations are further described below. The tested IVC and AVC HP reference software encodings provided very similar results for the tested cases. In most cases they had overlapping confidence intervals, in some cases (e.g. Party-Random Access) the IVC encodings were visually better than AVC HP encodings, and in some cases (e.g. Kimono-Low Delay) the AVC HP encodings were visually better than the IVC encodings. Section 2 of this report describes the test cases and encoding configuration constraints. Section 3 describes the subjective assessment process. Section 4 describes the data collection methodology and data processing for the data analysis. Section 5 presents numerical results and graphs for the test cases. Finally, section 6 provides a summary of the results.
