Certaines de ces technologies ne sont pas vraiment nouvelles, mais elles ont progressé récemment pour atteindre un niveau de maturité tel qu’elles représentent maintenant un marché considérable, tout en changeant petit à petit nos habitudes et notre manière de consommer la vidéo en général. Les technologies d’écrans ont rapidement évolués du plasma, LED, LCD, LCD avec rétro- éclairage LED, et maintenant OLED et Quantum Dots. Cette évolution a permis une augmentation de la luminosité des écrans et d’élargir le spectre des couleurs affichables.

  • SAF7115 Multistandard Video Decoder with Super-Adaptive Comb Filter
    SAF7115 Multistandard video decoder with super-adaptive comb filter, scaler and VBI data read-back via I2C-bus Rev. 01 — 15 October 2008 Product data sheet 1. General description The SAF7115 is a video capture device that, due to its improved comb filter performance and 10-bit video output capabilities, is suitable for various applications such as In-car video reception, In-car entertainment or In-car navigation. The SAF7115 is a combination of a two channel analog preprocessing circuit and a high performance scaler. The two channel analog preprocessing circuit includes source-selection, an anti-aliasing filter and Analog-to-Digital Converter (ADC) per channel, an automatic clamp and gain control, two Clock Generation Circuits (CGC1 and CGC2) and a digital multi standard decoder that contains two-dimensional chrominance/luminance separation utilizing an improved adaptive comb filter. The high performance scaler has variable horizontal and vertical up and down scaling and a brightness/contrast/saturation control circuit. The decoder is based on the principle of line-locked clock decoding and is able to decode the color of PAL, SECAM and NTSC signals into ITU-601 compatible color component values. The SAF7115 accepts CVBS or S-video (Y/C) from TV or VCR sources as analog inputs, including weak and distorted signals. The expansion port (X-port) for digital video (bi-directional half duplex, D1 compatible) can be used to either output unscaled video using 10-bit or 8-bit dithered resolution or to connect to other external digital video sources for reuse of the SAF7115 scaler features. The enhanced image port (I-port) of the SAF7115 supports 8-bit and 16-bit wide output data with auxiliary reference data for interfacing, e.g.
