Digital Cinema (D-Cinema) business is much more than feature films. Experimentation by showing programming other than feature films has been carried out since the early days of D-Cinema. Alternative content in Digital Cinema enables the cinema to become a multi-arts venue, attracting new and existing users by offering a range of vary products. We give an overview on this alternative content. Human...
Visual quality is one of the most important issues in digital cinema applications, and the most practical method to measure visual quality is using objective metrics. Several objective metrics that take into account perceived visual quality have been developed in the past few years; one of them is based on the structural similarity paradigm. To analyze the performance of these objective metrics for...
Even though several unequal erasure protection (UEP) schemes have been proposed for video streaming, it is still a challenge to define the optimal relative protection level for different data units. In this paper, we study loss-distortion modeling in realistic video streaming scenarios. The main observation is that when video streams with complex hierarchical structures and error resilience features...
This paper presents extensions to previous algorithms for unequal error protection (UEP) of multimedia encoded using embedded source coders. Whereas earlier work on this topic has considered the single-channel case only, we investigate the case where multiple parallel channels with possibly different loss characteristics are used. Such scenarios are becoming more relevant with the gradual deployment...
In this paper we present a model for measuring the quality of experience (QoE) of multimedia services. Our model consists of measurable and non-measurable parameters and describes a framework for quantifying the model parameters by transformation into an XML document with discreet values. The model has been validated by running a field trial over 4 weeks using 3G mobile phones for a video on demand...
