“…We selected the ACR method based on the results of previous studies, which have shown that this method is reliable for assessing the quality of low-resolution videos encoded at low bit rates and exhibiting both spatial and temporal distortions [20][21][22][23]. The ACR method with a 5-point discrete scale was used by the Video Quality Experts Group (VQEG) to conduct their evaluation of objective quality assessment models for low-resolution videos [24].…”

“…A maior diferença está na flexibilidade existente nas aplicações multimídia (diversos codecs, formatos de imagens, taxas de atualização temporal, etc.) perante a arquitetura mais restrita dos sistemas de televisão (BROTHERTON et al, 2006).…”

“…Apesar da existência de normas internacionais para avaliação subjetiva de vídeo, alguns tópicos ainda não estão bem definidos, como a definição de qual metodologia apresenta melhores resultados (BROTHERTON et al, 2006). Duas metodologias importantes atualmente são a ACR (ITU-R, 2002), bastante utilizada pelo grupo VQEG, e a SAM-VIQ (EBU, 2003), uma metodologia mais atual que foi criada especificamente para avaliação de vídeo em ambientes multimídia.…”

“…In fact, the perceptual attributes governing spatial audio quality might be highly influenced by the contents of the reproduced audiovisual material, thus, it becomes quite difficult to assess the benefits added by certain audio formats within a complete audiovisual context. Despite the fact that several well-known procedures exist [21], the joint assessment of audio and video quality is not a straightforward issue [26]. On the one hand, there is a complex interaction between auditive and visual stimuli in multimodal perception that makes it very difficult to isolate independent quality factors [40].…”
