影音問題一大堆

1.1080P升頻可以把所有影像訊號例如DVD,電視廣播,遊戲機等不足1080線解像度的訊號用插值計算方法變成1920 X 1080順序掃描訊號,如果你有支援1080P的顯示器材,咁做有一個好處係可以跳過顯示器較陽春的升頻線路,通常會有較好效果.但也有例外,宜試清楚才決定採不採用.
2.所有喇叭都必需要有擴音部份才會出聲,電視機也內置了擴音線路,但又係較陽春,只可普通發聲,獨立AV擴音機有較大的推動力,可外接較優質喇叭提音質,而且會內建一些環繞聲解碼線路,接齊一套六至八隻喇叭,可提供環繞音效.
3.喇叭線有喇線接位,唔係紅白色嗰啲,冇輸入,只有輸出的,輸出接喇叭.

好高興意見對你有用,我講灟咗環繞音效要訊號本身有做,AV擴音機才可以解碼,否則只是一些虛擬音效

1. 1080 is the number of horizontal lines. The definition of High Density for picture reproduction in AV is 1980 x 1080. This will give you very fine detail of movie reproduction. p is progressive, versus i which is interlaced or non-progressive. Progressive scan each line at one time while interlaced scan alternate lines at one time. Of course progressive is better. 1080p up-conversion or up-scaling function is to upgrade from lower number of lines to 1080p. Normally it is used in DVD player when the normal production of picture is just 560 lines. This will enhance the picture quality but as it is done by upscaling, it is not that good as true production of 1920 x 1080 picture now in HD DVD and Blu-ray Disc.

2. AV amplifier is a combination of amplifier, AV control centre, and digital decoder. The soundtracks of DVD discs normally are encoded by Dolby Digital or DTS. They need to be decoded before they can be reproduced. Most DVD players can decode Dolby Digital signal but not DTS. But even though they can decode Dolby Digital signal, many of them do not have 5.1 (five speakers surrounding the listening area plus one sub-woofer for low frequency sound reproduction) output. Hence, AV amplifier is required to decode and reproduce 5.1 soundtracks so that you can have theater like sound effects. AV amplifier of course is also to amplify the signal from the source, including DVD player, CD player, Tuner, DVD recorder, etc., and output to the speakers. It is also an AV control centre as many AV equipments (DVD player, CD player, DVD recorder, TV, Projector, Video Game Player, Cassette Deck, Video Cassette Deck, Tuner, etc.) can all be connected to the AV amplifiers and can use it to choose what to reproduce and where to output.

3. Speaker cables should be connected to the speaker jacks in the AV amplifier, not the input / output jacks which are used to connect to the source or the output equipment.

Hope I can answer your questions.
