Secuenzia, as an expert company in the area of the security of digital content, has worked in the study and implementation of DRM systems in various projects. The DRM (Digital Rights Management) are management systems and control access to the encrypted contents of payment, with multiple applications for Pay-TV, video on demand, PVR and music downloads.

These systems are based on the addition of metadata to digital content, which allows business models much more flexible, because in this way, intelligence in the management of content increases. For example, when you download a film, you can define the number of times that it can be seen, the interval of time in which is allowed its viewing, or the number of copies that can be done of the same one.

Secuenzia has collaborated in the implantation of a system DRM during the last two years, within the device high resolution multimedia that tries to develop the European project Blaze.

Secuenzia is working in this project with the following companies in Spain, Austria, France and Holland:

The project Blaze                

With the advance of the new technologies in the televisions, as LCD, Plasma or LCOS, the big screens are increasingly attainable, because of this industry will tend to the high definition (HD).

La alta definición tiene una resolución de 1920x1080 pixels y un formato panorámico 16:9, frente a la resolución 720x576 de la definición estándar. Esto implica una calidad de imagen muy superior a la actual, pero implica a su vez, un mayor ancho de banda en la difusión, y una capacidad de almacenaje muy superior para los discos HD.

The high definition has a resolution of 1920x1080 pixels and a panoramic format 16:9, as opposite to the resolution 720x576 of the standard definition. This implies a quality of image much greater than the present one, but it implies as well, a greater bandwidth in the diffusion, and a greater storage capacity for disKs HD. They have appeared two different standards in optical disks of HD. The HD-DVD, sponsored by Toshiba and the forum DVD, and the Blu-Ray, defined by a companies partnership, where Sony and Philips stand out. The technology used by both partnerships, is based on the utilization of a laser of blue colour, instead of the red current one, that allows storing more capacity of information in the same disk surface.

The European project Blaze, is based on the Blu-Ray standard and aims to integrate into a single device:

1. A player/recorder disks Blu-Ray (BD-ROM)
2. A receiver of contents HD. They can be diffusion contents, VOD contents or disks contents, with their DRM associated.
3. A hard disk that stores contents in Blu-Ray format.
