ابتدا...
اینطور به خاطر دارم که پیش‌تر بحثی درباره‌ی خرید DVD Player داشتیم که پیدایش نکردم. اگر دوستان دیدند لطفا همین‌جا لینک بدهند تا دو تاپیک ادغام شوند. ممنون.
سپس...
نکاتی درباره‌ی خرید سیستم پخش تصویر به ذهنم می‌رسد که با دوستان عزیز به اشتراک می‌گذارم. بخشی از این مطالب مجهولاتی است که هنوز پیگیر پاسخش نشده‌ام و بخشی دیگر تجربیات یا اطلاعات بدست آمده است. در ضمن منظورم از سیستم پخش تصویر هر چیزی است که تصویر را پخش می‌کند مثل DVD Player ، BluRay ، PS3 یا حتی کامپیوتر.
هدف این است که بدانیم با صرفه‌ترین و منعطف‌ترین گزینه‌ی امروزی برای پخش تصویر چیست و راه‌های تست و بررسی آن کدام است.
همانطور که می‌دانید قریب به اتفاق فروشندگان این‌گونه محصولات ضمن آنکه اطلاعات فنی در حد زیر صفر دارند، چنانچه ویدئو SONY T7 موجودی فعلی انبارشان باشد اصرار دارند ثابت کنند از HD و DV و هرآنچه امروز برترین است، برتر است! بیچاره خریداری که بودجه‌ای محدود دارد و نوکیسه یا متمولی نیست که هر روز برند عوض کند و آنقدر پول دور بریزد تا به مطلوبش برسد.
دیروز مطلب ارزشمندی را در اینترنت کشف کردم که بخشی قابل قبول از فرآیند تست و آزمون سیستم پخش کننده را سر و شکل میدهد:
ابتدا این فایل 700MB را دانلود کنید! نگران نباشید لینک مستقیم است و می‌توانید به‌راحتی از نرم‌افزارهای مدیر دانلود بهره‌مند شوید:
سپس توسط نرم‌افزار Nero یا هر نرم‌افزار دیگری که فایل ISO را می‌شناسد، از این Image File یک CD بسازید. (قابل توجه دوستان مبتدی در امور رایت سی‌دی: فایل ISO را روی CD رایت نکنید، بلکه این فایل را در بخش مربوطه‌ی نرم‌افزار بارگذاری کرده و بوسیله‌ی آن CD تولید کنید که محتویاتش، محتویات این فایل CD IMAGE است.)کد:http://divxtest.isstar.net/DivXTestCDv2.0.by.bbdoc_forum.surdvd.com.iso
حالا سنگ محکی ارزشمند در دست شما است تا همه چیز یک CD/DVD/HD Player را که مدعی است انواع فرمت‌های Divx, Xvid, MP3, Jpeg, … را می‌شناسد و از انواع زیرنویس‌ها پشتیبانی می‌کند و قادر به پخش انواع Resolution و Bitrate است را بیازمایید.

can therefore be used instead of the other tests that follow. There is, a circle to check the
Horizontal/vertical ratio, convergence, geometry and definition test cards.
B /C/D : Purity Red-Green-Blue test card: You can verify that your screen gives perfectly
uniform colors with these test cards. If you see a stain it means you have a purity or
convergence problem.
E/F : Black and white test cards. You can check the contrast and brightness of your television
with these test cards.
G : Convergence test card. With this test you can check (or setup, for certain screens) the
picture geometry.
H : Grey range test card). With this test you can check the blackness level of your screen as
well as its right brightness.
I : Colour bars test card). With this test you can check that there is no disturbance in the video
signal and that no colour is missing.
