Digital stereo sound cinema was built with reference to the standard multi-function hall to improve the acoustic environment forces - On the above transformation hall auditorium acoustics design, decoration and construction and manufacturing techniques

Tube, box jacket connections, and more well-grounded. All power cables must be tin-plate welded joints. (2) a variety of wall construction and renovation process ① shape and sound-absorbing material of the bearing and fixed using 75mm metal frame. To make a solid wall decoration safety and weight distribution of the load beam in the building wall, in the Qiang Zhu and beam with angle iron expansion bolt 5, to stretch a fixed keel, the decoration on the wall bearing the main load of material . ② wall decoration style all wood materials are used, that is 1.8mm thick man-made solid wood boards. Wood panels inside the fire to be brushing twice oil paint,[link widoczny dla zalogowanych], polyester paint surface shape in 4 over the polished matte spray paint. ③ 60mm thick sound absorbing material is rock wool felt pieces, made with Blockboard 60mm thick 1560mm high 480mm wide border, the border around the outside edge down to make 45-degree angle, the surface with a fine steel mesh reinforcement to do; absorption material block finishes with tear strength 10kgf, just soft-degree 70-50mm, water fastness and light fastness of 4 grade, fire retardant khaki coefficient of ≤ 10cm/min 100Acrylic decorative fabric (fabrics). ④ dado (also a shadowing decorative radiator cover) modeling man-made timber for the 1.8ram wood panels, for the benefit of accelerated heating cycle, the use of air entered the lower part, upper part of the style of the outlet opening, the opening to install matte brown metal grille. Support the installation of relying dado 70mm metal frame, with the upper wall decoration for the overall structure; to public safety,[link widoczny dla zalogowanych], dado finish flush with the door frame base. ・----- 40t. -, - Modern film technology No. 7/2009AD ● DMOt / ON ~ \resonance); browser and install the sliding door off the outside. ⑥ all on the shelf on the wall of wood materials (such as the keel, plate) inside of the fire safety requirements must be strictly in accordance with fire retardant paint brushing oil. (3) movie screen frame welding, the installation process to install the film screen frame using structural steel mobile stand. Mobile frame chassis with a 40 × 80 (mm) square steel welding, roller bearings with 200mm wide-wheel caster surface of plastic products; screen support frame with a 20 × 40 (ram) square steel welded, polished smooth, brushing against rust paint and painted matte black cover. In order to smooth the fixed screen,[link widoczny dla zalogowanych], must be requested by manufacturers,[link widoczny dla zalogowanych], plastic pipe will penetrate the screen edges (can be ~) 20mm of PPR pipe), tied with a dark stretch nylon rope solid stent border. Conclusion I presided over the construction of the theater hall of the overall transformation of a few, decoration and equipment installation completed, by, performances and film screenings trial, no obvious acoustic defects. Show digital stereo video, sound field positioning accuracy, the basic balance of frequency response, voice is relatively clear,[link widoczny dla zalogowanych], the subjective effect of the basic line with digital stereo audio visual environment for the cinema.

Japan's use of NGN network to transmit digital film in progress in the global film industry film screenings from film to digital cinema projection of the change process, Japan has lagged behind. According to statistics, in the United States has 38,834 of the nearly 5,000 screens in the realization of the digital screen, while Japan's 3359 screen showing only a hundred digital cinema screens, in order to change this backward situation as soon as possible, by the NTT Group, Japan (Nippon Telegraph and Telephone set of digital film transfer diagram chart 1NGN group) and the Japanese film company Toho, 14 units jointly launched the \After a year of practice, is now perfectly complete this task. This trial is a subsidiary of NTT from Japan, \Currently, the Toho film completed in 47 districts of the 2-3 block digital screen in Kadokawa areas, this summer there will be seven regions of 19 digital screens, and plans in the spring of 2012 to achieve full digital.
