PIP、POP跟PBP

許多新型的電視或者是電視盒, 內部都會有子母畫面的功能,

當然, 功能與性能各有不同.

當然, 子母畫面不能照字面翻成英文 Children-Monther Picture.

子母畫面就我目前所查到的資料,
顯示的模式有分為 PIP、POP跟PBP.

所謂的 PIP (Picture-in-Picture), 就是在一個主畫面中, 內有個小窗格畫面, 如下

PIP 的定義:

Picture in Picture (PiP) is a feature of some television receivers and similar devices. One program (channel) is displayed on the full TV screen at the same time as one or more other programs are displayed in inset windows. Sound is usually from the main
program only.

再來 POP , 直接看圖比較快,

PBP , 簡單的講, 就是畫面分成左右兩邊.

Picture and Picture (PAP, P&P) (commonly referred to as PBP - Picture by Picture) is a related feature showing two programs side-by-side on the screen, with the sound from one program being played through the speakers, and the sound from the other being sent to headphones.

H/V Total

在修改 LCD AD board project 時, 裡面有一些參數名詞常會弄混,
先把找到的記下來.

HTotal = HSize + HSync + HFrontPorch + HBackPorch

HSize 是 H 的 Active Size

V 的部份也是同上.

這些都跟 panel spec 上的參數有關

顯示一個 pixel 會跟 dot-clock 有關,
一個 pixel 裡會有三個 dot (RGB).

CKD? SKD?

一開始聽見人家在講 SKD, 總以為自己聽錯,
一直以為是軟體在講的 SDK,
上網找了一下資料,

SKD (Semi-Knocked Down) 半散裝半成品
CKD (Completely Knocked Down) 全散裝半成品

這種情況很常見, 以前在學經濟學時,
一開始聽見 MFC 也一直跟 M$ 的 MFC 搞混呢.

寫寫一些在工作或生活上的鎖事

是為了備忘? 還是為了記錄 ?

不知道.
