ADI launches new ultra high definition video signal processor: ADV8005
ADV8005 is a multi input video signal processor that can de interlace standard definition (SD), enhancement (ED), or high definition (HD) video data and adjust it to ultra-high definition (UHD) format. It can generate screen display bitmap (OSD) and utilize two high-definition multimedia interfaces (HDMI) in the form of OSD overlap ®) The transmitter and a video encoder output the video.
The 60 bit TTL video port can input video to ADV8005 in various ways: using a 48 bit TTL pixel port, using a 24 bit external OSD TTL pixel port, or using a device with an HDMI transmitter (such as ADV7850). ADV8005 supports many formats in CEA-861-F and VESA specifications, as well as other widely used timing formats.
ADV8005 has a main video converter and an auxiliary video converter, which can achieve synchronous output of multiple different resolutions. The main video adjuster can be adjusted up to 4k × 2k mode. The auxiliary video adjuster can be adjusted up to 1080p or UXGA images: using the auxiliary video adjuster can perform a 4k × 2k downward adjustment operation, freeing up the main video adjuster for other video processing.
The ADV8005 main video tuner can perform high-performance, motion adaptive interlace to line conversion on standard definition and high-definition content. ADV8005 has also added other features to adjust pixel clock frequencies up and down for VESA format videos below 300 MHz.
Detail enhancement and image enhancement techniques such as random denoising, mosquito denoising, and block denoising can help improve the final image quality. The frame rate converter of ADV8005 can achieve conversion between common frame rates and supports simultaneous output of two different frame rates under specific conditions.
ADV8005 can receive OSD information from external OSD sources through one of its input terminals, or generate a high-quality, bitmap based OSD internally. The internal OSD has a high degree of flexibility, allowing system designers to easily adopt features such as scrolling text and animation in various color depths (up to 24 bit true color).
The OSD development tool (Blimp) provided by ADI can demonstrate the design, debugging, and simulation of OSD before integrating system applications. After the design is completed, the OSD development tool will automatically generate code. Before integrating the system application, the system application programming interface (API) will be added to this code; In addition, OSD design resources will also be generated, which must be downloaded to external SPI flash memory.
A standard definition/high-definition video encoder with one or two HDMI transmitters and/or six DACs can be used to output video from ADV8005. Six 12 bit NSVs ® Video DAC supports composite (CVBS), S-video (Y/C), and component (YprPb) analog outputs of standard definition, enhancement, and high-definition video formats. The oversampling of 216 MHz (standard definition and enhancement) and 297 MHz (high definition) eliminates the need for external output filtering. ADV8005 provides Rovi ® And non Rovi versions.
Both HDMI transmitters on ADV8005 support 4K × 2K and all mandatory and multiple optional 3D video resolutions. Each transmitter has an Audio Feedback Channel (ARC) receiver. ADV8005 can receive up to six channels of I2S, S/PDIF, Direct Digital Stream (DSD), as well as high bit rate (HBR) transmitted from a serial video receiver or externally available audio input pin.
ADV8005 supports I2C protocol and communicates with the system microcontroller.
