Demolandia Demolandia is, essentially, an audiovisual library where you will find a great diversity of images, audio and video files related to the cinema, as well as trailers of the latest films and interesting information for technology lovers. Since 2010 our priority has been to make the necessary tools available for our users to verify their audiovisual devices, whatever the range is. However, what do we mean exactly? Each audio device we acquire comes with specifications and certifications that guarantee a certain quality and fidelity level in the sound that will come out of them.

At Demolandia we are responsible for collecting a library with the most useful and important demonstration files, trailers and tests that have been appearing along with those equipment, codified to the best quality and with less loss to guarantee the greater fidelity in the sound, thus ensuring an accurate evaluation of the performance of your speakers, amplifiers, headphones or any other audio device. In conclusion, who are we? At Demolandia we are enthusiasts of technology, lovers of high quality and fidelity, that we have decided to facilitate to our users the use of the maximum potential of their audiovisual devices and provide them with such an amazing vision of the history and evolution of these technologies. Therefore, if you are one of those who checks each label (Dolby, THX, DTS) in the equipment boxes, movies, DVD, Blu-Rays or video games you acquire, you have come to the right place. Home Theater Trailers Resolutions: SD: (480p, 576p): For SD Dolby intros, the most usually format is the MPEG-2 format a resolution of 720×480 pixels (NTSC) and 720×576 (PAL), using an average bit rate of about 5 Mbps (variable bitrate mode, which distributes the bits available according to the complexity of each frame). The maximum allowable rate is 9.8 Mbit/s, which is rarely used for practical reasons.

The common container for SD trailers is vob. Most commercial DVD publishers often use maximum values of 7.8 to 8.5 Mbps, is possible to use a special mode called “16:9 anamorphic” that encoding a panoramic film using all the available resolution; in fact the vast majority of widescreen movies on DVD are encoded in this resolution, without recording the black bars as if it was part of the image. Just needed the black bar is added to fill the image to a 16:9 (if movies with an aspect ratio greater than 16: 9, such as 21: 9 format that usually abound in today's cinema). Full HD (1080p): UHD 2K: It is an emerging UHD standard for digital film resolutions and computer graphics. The name derives from the horizontal resolution, which is approximately 2,000 pixels. 2K represents the horizontal resolution because there are numerous aspect ratios used in films. The vertical depends on the aspect ratio with which the director decides to work.

The resolution of UHD demos is 2,048 × 1.0803 (17: 9) and 2.2 megapixels. There are some utilities to test the correct UHD 2K and full 4K calibration in our section. DTS Trailers (Digital Theater System): have digital audio encoding surround system that allows 6 independent surround audio channels into a single DTS compressed signal. Apart from being used for DTS trailers, DTS also used in films and “special places” such as theme parks or virtual simulators, in which case can hold up to 8 independent DTS surround channels into a single signal, and can synchronize multiple signals to get a fully independent unlimited number of channels. THX Trailers: THX is a high-fidelity audio and video standard for THX movie theaters and home theaters compatible systems. THX certified was created in 2002 developed by Tomlinson Holman at THX George Lucas company. In 1983, to assure that the soundtrack for the third Star Wars film, Return of Jedi would be accurately reproduced in the best places.

THX is not a recording technology format for the: All sound are encoded in digital formats like Dolby Digital, SDDS, DTS or analog like Dolby Stereo or Stereo Ultra can be shown in THX. It is primarily a quality assurance. You can find a lot of vob, m2ts and mkv demos on Demolandia for testing it. THX certified theaters provides high-quality, predictable video and sound environment to ensure that any soundtrack reproductions such as those in our section mixed in THX system will sound as near as possible to THX sound engineer intentions. THX provides certified theaters with a special crossover circuit. THX certification of the auditoriums includes specific acoustic and other technical requirements like floating floor, acoustically treated walls, walls without parallel walls (to reduce standing waves), a perforated screen (to ensure continuity in the center channel) and NC30 rating of background noise (avoid the noise provided by air conditioners units and projection systems).
