ADI ADV8005多输入视频信号处理方案

ADI公司的ADV8005是多输入视频信号处理器,是全12位4:4:4 YCbCr内部处理,运动自适应的逐行扫描,多个视频处理通路并支持画中画功能(PiP),具有标准清晰度(SD),增强清晰度(ED)和高清(HD)视频数据,支持CEA-861-F和VESA标准中的许多格式,主要用在高端A/V接收器,DVD播放器/刻录机,视频会议和分配以及HDMI分隔器视频墙.本文介绍了ADV8005主要特性和详细功能框图, 应用系统框图以及Advantiv EVAL-ADV8005-SMZ视频评估板主要特性,框图,电路图,材料清单,PCB元件布局图和PCB设计图.
The ADV8005 is a multiple input video signal processor that can deinterlace and scale standard definition (SD), enhanced definition (ED), or high definition (HD) video data to ultra HD formats; generate a bitmap on-screen display (OSD); and output the video with OSD overlaid on two High-Definition Multimedia Interface (HDMI®) transmitters and a video encoder. The 60-bit TTL video port can be used to input video to the ADV8005 in a number of ways: using the 48-bit TTL pixel port, using the 24-bit external OSD TTL pixel port, or from a device with an HDMI transmitter such as the ADV7850.
The ADV8005 supports many of the formats outlined in the CEA-861-F and VESA specifications, as well as several other widely used timing formats. The ADV8005 features primary and secondary video scalers that enable simultaneous output of multiple different resolutions. The primary video scaler can upscale to 4k × 2k modes. The secondary video scaler can upscale to 1080p or UXGA graphics. 4k × 2k downscaling is performed using the secondary video scaler, leaving the primary video scaler available for other video processing.
The ADV8005 primary video scaler can perform high performance, motion adaptive interlaced to progressive conversion on SD and HD content. Additional functionality has also been added to ADV8005 to facilitate upscaling and downscaling to VESA formats with pixel clock frequencies below 300 MHz.
