The HMP8117 is a high quality NTSC and PAL video decoder with internal A/D converters. It is compatible with NTSC M, PAL B, D, G, H, I, M, N, and combination N (NC) video standards. Both composite and S-video (Y/C) input formats are supported. A 2-line comb filter plus a user-selectable chrominance trap filter provide high quality Y/C separation. User adjustments include brightness, contrast, saturation, hue, and sharpness. Vertical blanking interval (VBI) data, such as Closed Captioning, Wide Screen Signalling and Teletext, may be captured and output as BT.656 ancillary data. Closed Captioning and Wide Screen Signalling information may also be read out via the I2C interface. The Videolyzer™ feature provides approved Macrovision™ copy-protection bypass and detection.
The HMP8117 is a high‑quality NTSC and PAL video decoder that supports both composite and S‑video (Y/C) inputs. It provides a range of digital output formats including 8‑bit and 16‑bit 4:2:2 YCbCr as well as 15‑bit and 16‑bit RGB, and includes the Videolyzer feature for Macrovision copy‑protection bypass and detection.
The device uses a digital PLL architecture with a selectable CLK2 clock (e.g., 27 MHz for NTSC) and offers extensive video processing functions such as brightness, contrast, saturation, hue, sharpness, and color‑gain control. External anti‑alias filtering is recommended for optimal performance, and the chip is RoHS‑compliant with Pb‑free options.
