However, S3D programming has not gained significant traction with viewers because of the higher price of 3D TVs and the requirement that viewers wear active glasses. These glasses act like shutters that display one of two 3D images for each eye to give the perception of depth. S3D sports was supposed to be a success but due to limited viewer adoption of S3D services to the home, ESPN shut down ESPN 3D, the first 3D network, in June 2013. The cost of S3D filming is incrementally higher because it requires additional cameras and crew.
Data compression). Many video coding methods are lossy where information that is removed cannot be recovered. This leads to irreversible distortion of the original video. The distortion can be minimized because information that the humans cannot perceive is typically removed. On the other hand, lossless video coding will not impact video quality when the video is decoded for display. In many instances, lossless coding is not used since the coding efficiency is lower compared to lossy coding. In addition, videos that are coded losslessly may take a longer time to decode due to the larger frame sizes.
In addition, the human eye can tolerate more distortion to the high-frequency components than to the low-frequency components. 2 Discrete Cosine Transform The discrete cosine transform (DCT) expresses a finite sequence of discrete data points as a sum of cosine functions oscillating at different frequencies. DCT is widely applied to lossy compression of video and images, and is well suited for image areas of roughly uniform patterns and complexity. DCT is similar to the discrete Fourier transform (DFT) but uses only real numbers.
