    3. Conclusion

    The screen is a key element in the image chain. The quality of an HD display depends both on the quality of the optical reproduction of images on the display "slab", and on the quality of the input digital signal processing circuits.

    The design, implementation and operation of a complete HDTV chain, from lens to screen (from glass to glass), requires a large number of native and compression formats, parameters and technologies to be taken into account. Making this chain seamless is therefore particularly complex. Not only the bitrate, but also the performance of the compression tools, the capture equipment and the display equipment will decisively determine the quality of the images seen by end-users. It is therefore essential to carry out objective and subjective quality measurements throughout the chain.
