Digital video quality is always an issue after the processing of data on a storage unit and the transfer of the recorded material onto a computer. The problem comes from the fact that digital video quality can be distorted or impaired during processing, even if the incidence rate for deterioration is much lower as compared to analog videos for example. Some applications even require an evaluation of the digital video quality.

According to expert criteria, you can evaluate the digital video quality by analyzing different sequences from the database. From this perspective, the performance of a certain system depends on the dynamic features of the input video signal, which includes the spatial and the amount of motion in the video. The objective approximation of digital video quality is performed by mathematical models based on metrics. The objectivity of the analysis only results when you introduce the data into a computer program to achieve the actual measurement.

Peak-signal-to-noise ratio or simple signal-to-noise ratio are the traditional ways of determining digital video quality; multimedia applications use both types of services for very practical and relevant results. Sometimes several other tests are necessary before the digital video quality for compression-decompression can be determined. Such tests are usually impractical and time consuming, and they have no relevance for the average consumer.

As for subjective digital video quality this is actually the viewer’s opinion on a video that has passed through processing. Normally, a trained expert should judge the parameters, yet it is common practice to take a group of experiments and show them several video sequences. The evaluation is performed per sequence and the reactions and opinions are recorded for analysis. Regardless of the evaluation method, digital video quality is always superior to analog videos. And the quality is all the more relevant for larger visuals than for smaller ones.
