一、會議室總體方案設計觀念
1、 Overall scheme design concept of conference room
會議室/課室內布局應大氣而樸素,能真實地體現當場人物和大會自然環境,使與會人員有現場感、一體感以做到視覺效果、語言溝通交流的顯著成績。遠程控制會議室/課室中傳輸的圖象包含人物、景色、數據圖表、文本等,應清晰可辨。遠程控制會議室/課室內要維持事項的溫度、環境濕度、室內通風度,使與會人員覺得舒服、當然。
The layout of the conference room / classroom shall be atmospheric and simple, which can truly reflect the on-site people and the natural environment of the conference, so that the participants have a sense of scene and integration, so as to achieve remarkable results in visual effect and language communication. The images transmitted in the remote control conference room / classroom include characters, scenery, data charts, texts, etc., which shall be clear and legible. The temperature, ambient humidity and indoor ventilation in the remote control conference room / classroom shall be maintained to make the participants feel comfortable and natural.
二、會議室合理布局規定
2、 Regulations on reasonable layout of meeting rooms
為了更好地保證多媒體會議系統圖象的收看實際效果和避免顏色對人物拍攝造成的“絢麗”或“返光”實際效果,電視背景墻應采用單一勻稱的淺顏色,而多媒體會議系統室其他墻面、餐桌布、毛毯、吊頂天花板等應與電視背景墻相符合,電視背景墻不適合應用中畫幅。提議桌椅板凳及墻面采用淺卡其色或淺青藍色。桌椅不適合采用布藝沙發式,也不適合采用高椅背,防止遮擋后邊的與會人員。
In order to better ensure the actual viewing effect of multimedia conference system images and avoid the "gorgeous" or "back light" actual effect caused by color on character shooting, the TV background wall shall adopt a single and symmetrical light color, and other walls, dining table cloth, blanket, ceiling, etc. of multimedia conference system room shall be consistent with the TV background wall, The TV background wall is not suitable for the picture frame in the application. It is proposed to use light khaki or light cyan for tables, chairs, benches and walls. Tables and chairs are not suitable for cloth sofa type, nor are they suitable for high chair back to prevent covering the participants behind.
影響畫質的一大要素,是主會場四周的景色和顏色,及其桌椅板凳的色彩。一般不宜“白”、“灰黑色”這類的色彩,這二種顏色對身體將造成“返光”及“奪光”的欠佳效用。因此 不管墻面四周、桌椅板凳均采用淺色系色彩比較適合,如墻面四周淺黃色,淡綠,桌椅板凳淺咖色等,南方地區宜用冷色調,北方地區宜用暖色調。對拍攝情況(被攝人物身后的墻)不適合掛有山水國畫等景色,不然將提升拍攝目標的數據量,不利多媒體會議系統圖象品質的提升 。
A major factor affecting the image quality is the scenery and color around the main venue, as well as the color of tables, chairs and benches. Generally, colors such as "white" and "gray black" are not suitable. These two colors will cause poor effects of "returning light" and "seizing light" on the body. Therefore, no matter around the wall, tables, chairs and benches, light colors are more suitable, such as light yellow, light green around the wall, light coffee color of tables, chairs and benches, cold colors should be used in the South and warm colors should be used in the north. For the shooting situation (the wall behind the subject) it is not suitable to hang landscapes, traditional Chinese paintings and other scenery, otherwise the amount of data of the shooting target will be increased, which is not conducive to the improvement of the image quality of the multimedia conference system.
三、會議室聲學材料規定
3、 Regulations on acoustic materials for meeting rooms
為確保多媒體會議系統聲音絕緣層與吸音實際效果,會議系統的房間內鋪有毛毯、吊頂天花板、四周墻面內都配有隔音毯,窗子應采用雙層中空玻璃,進外出應考慮到隔音降噪設備。另外吸音不必過多,防止聲音發干。
In order to ensure the actual effect of sound insulation layer and sound absorption of the multimedia conference system, the room of the conference system is paved with blankets, ceiling, and sound insulation blankets are equipped in the surrounding walls. The windows shall adopt double-layer insulating glass, and the sound insulation and noise reduction equipment shall be considered when entering and leaving. In addition, there is no need to absorb too much to prevent the sound from drying.
依據聲學技術規定,一定容量的會議室有一定混響時間的規定。一般來說,混音的時間過短,則聲音枯燥乏味發澀;混響時間太長,聲音又混淆不清。因而,不一樣的會議室都是有其的混響時間,如混響時間適合則能清理新聞發言人的聲音,遮蓋噪音,提升大會的實際效果。音箱的布局應以會議室獲得勻稱的音場,且能避免 聲音傳回。會議音響系統的功率放大電路應采用多個小容積功率放大電路集中化設定在同一主會場的方法,用有效的走線和轉換系統軟件,確保會議室在毀壞一臺功放機時,不導致主會場聲音終斷。聲音數據信號鍵入功率放大電路以前,應采用均衡器和反饋抑制器開展解決,以提升 聲音數據信號的品質。
According to the acoustic technical regulations, the conference room with a certain capacity has a certain reverberation time. Generally speaking, if the mixing time is too short, the sound will be dull and astringent; The reverberation time is too long and the sound is confused. Therefore, different conference rooms have the best reverberation time. If the reverberation time is appropriate, it can clean up the voice of the press spokesman, cover the noise and improve the actual effect of the conference. The layout of the speaker shall obtain a symmetrical sound field in the conference room and avoid sound transmission back. The power amplification circuit of the conference sound system shall adopt the method of centralized setting of multiple small volume power amplification circuits in the same main venue, and use effective wiring and conversion system software to ensure that the sound of the main venue will not be interrupted when a power amplifier is destroyed in the conference room. Before the sound data signal is input into the power amplification circuit, equalizer and feedback suppressor shall be used to improve the quality of sound data signal.
