Abstract :
In this study we investigate the image quality of two video codec standards (D10 and DV25) for broadcasting purposes. Different video sequences from the Flemish public broadcasting institute (VRT) archive were produced in Betacam format and subsequently compressed following the two codecs. Then, two instrumental measures being the Peak Signal to Noise Ratio (PSNR) and the Structural SImilarity Measure (SSIM) were used to assess the compressed video quality quantitatively. A psychovisual experiment based on the Multidimensional Scaling Framework (MDS) was set-up to assess the video quality qualitatively. Both approaches were compared and indicated unanonymously the preference for the D10 codec over the DV25 codec.
