Input 1-1 Input signal format (Digital input) Digital data port supports the following signal input formats. 24bit (4:4:4) YCbCr/RGB: NTSC/PAL (480i/576i), 480p, 576p, HD (1080i/720p) 16bit (4:2:2) YCbCr: NTSC/PAL (480i/576i), 480p, 576p, HD (1080i/720p) 8bit Based on ITU-R BT656system (H/V sync input is needed): NTSC/PAL (480i/576i) Digital 2 system input such as 16bit (4:2:2) YCbCr + 8bit (ITU-R BT656), 8bit (ITU-R BT656) + 8bit (ITU-R BT656) are possible 1-2 Input signal format (Analog input) Analog port can be connected to all of the following input. CVBS × 2ch: Composite input 2CH S-Video: S video input 1CH YPbPr input (Supports 480i/576i, 480p/576p, 1080i, 720p input): Component input 2 system 2. Digital Video Decoder Block This LSI carries video decoder which converts the video signal of NTSC, PAL and SECAM or Component video signal into digital picture signal. It decodes Digital picture data by inputting the video signals of NTSC, PAL and SECAM which are converted from Analog to Digital. It supports composite video signal, S video signal and component signal (480i). 3. De-interlacing Block When inputting NTSC (480i) and PAL (576i), it can implement motion adaptive De-interlacing, cinema mode de-interlace, 3D noise reduction and cross color/cross luminance canceller. At 480p, 576p, 1080i, 720p, this block is set to the through state. 3-1. Motion adaptive De-interlacing At De-interlacing block, it operates the movement detection to every pixel that inputted. As a result, it does interpolation between front and back field to the pixel that judged as static, and does interpolation inside field to the pixel that judged as move. So de-interlacing can be done. In that case, as for interpolation in between field of move part, it is possible to produce less notched (less-jaggy) and smooth image because of interpolation that considers the correlation of oblique direction. |
