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.
Detail enhancement and image enhancing techniques such as random, mosquito, and block noise reduction allow improved final image quality. The frame rate converter of the ADV8005 allows the conversion between common frame rates with support to output two different frame rates simultaneously under certain conditions.
The ADV8005 can accept OSD information from an external OSD source on one of its inputs, or it can internally generate a high quality, bitmap-based OSD. The internal OSD is highly flexible and allows the system designer to easily incorporate features like scrolling text and animation in various color depths up to 24-bit true color.
Analog Devices, Inc., provides an OSD development tool (Blimp) to assist in the design, debug, and emulation of the OSD prior to integration with the system application. When the design is complete, the OSD development tool automatically generates code to which system application programming interfaces (APIs) can be added before integration with the system application and an OSD design resource, which must be downloaded to an external SPI flash memory.
Video can be output from the ADV8005 using one or both of the HDMI transmitters and/or the six-DAC SD/HD video encoder. The six 12-bit NSV® video DACs allow composite (CVBS), S-Video (Y/C), and component (YPrPb) analog outputs in standard, enhanced, and high definition video formats. Oversampling of 216 MHz (SD and ED) and 297 MHz (HD) removes the requirement for external output filtering. Rovi® and non-Rovi variants of the ADV8005 are available.
Both of the HDMI transmitters on the ADV8005 support 4k × 2k and all mandatory and many optional 3D video resolutions. Each transmitter features an audio return channel receiver (ARC). The ADV8005 can receive up to eight channels of I2S, S/PDIF, direct stream digital (DSD), and high bit rate (HBR) audio passed from either the serial video Rx or from the externally available audio input pins.
The ADV8005 supports the I2C protocol for communication with the system microcontroller.
