What's on TV: A large scale quantitative characterisation of modern broadcast video content

A Study of High Frame Rate Video Formats

“…An extensive analysis of recent broadcast content has shown that the distribution of five uncorrelated factors (generated using PCA) can be used to quantify the representativeness of a small-scale video database compared to the vast population of modern broadcast content (in this case BBC Redux data) [43].…”

“…Therefore to ensure that methods benchmarked on a video database are applicable to real-world applications, and that lasting conclusions are relevant to a wider audience, it is crucial that a video database contains content which is archetypical of broadcast content. Using the method outlined by Moss et al [43], we can ascertain whether there are any similarities between BVI-HFR and BBC broadcast content (14075 sequences from BBC Redux [49]). In order to acheive this we need to calculate two further descriptors: DTP (Dynamic Texture Parameter) [50] and TP (Texture Parameter) [50] to estimate complex and irregular motion, and static textures respectively.…”

“…The cumulative distribution function (CDF) of the five factors identified in[43]. The blue curves show the results from a high density sampling of BBC broadcast content, while the red curves are calculated from the source sequence (120 fps) in the BVI-HFR video database.…”

Video texture analysis based on HEVC encoding statistics

“…Further characterisation of the HomTex dataset was performed using the methodology of [14], which offers a way of measuring how well a given dataset reflects the characteristics of broadcast consumer video. The dataset was parameterised using low level features, which were then transformed into orthogonal factors.…”

“…An important feature of this dataset is that it is representative of broadcasting video content, as suggested by the methodology proposed by [14] (Section II). The second contribution of this paper is to offer a better understanding of the performance of HEVC on different texture classes.…”
