FUNCTIONAL DESCRIPTIONS
TV Encoder encodes digital pixel data to ITU-R BT.656 format. TV Encoder largely consists of 4 parts.
The first part is the Enhancer & Encoder block. The Enhancer & Encoder block contains the encoder and the
image enhancer. The image enhancer takes charge of a image enhancing by controlling Black & White Stretch,
Gamma, Bright, Contrast and so on. We can get the image which is reinforced with some effect. And then the
encoder generated TV signal which is ITU-R BT.656 format.
DATA PATHS
To display the different image at LCD and TV, there are two paths.
(Post Processor ->) Display controller -> LCD panel, path (1) (in figure).
Data are loaded directly from memory by either Post-Processor or Display Controller. After Display Controller
transmits data to LCD.
TV scaler -> TV Encoder, path (2) (in figure).
Data are loaded by TV scaler. It treats data that covert properly size and color-space. Finally, it sends them to TV
encoder.
This path is able to display different images between LCD and TV encoder.
