The ADV8005 is a multiple input video signal processor that can de-interlace and scale SD, ED, or 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.
Video can be input into 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 and VESA specifications, as well as several other widely used timing formats.
Using two external DDR2 memories, the ADV8005 can perform high performance, motion adaptive interlaced to progressive conversion on SD and HD content. Using a single DDR2 memory, the HD de-interlacing is limited to intrafield.
The ADV8005 features primary and secondary video scalers that enable simultaneous output of multiple different resolutions. The primary and secondary video scalers are capable of up- and down-scaling video from 480p to 4k x 2k. Additional functionality has also been added to ADV8005 to facilitate upand down-scaling 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 for 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 has a flexible digital core that allows the user to configure the part in several different modes; for example, using a single video processing channel, using dual video processing channels, or displaying OSD on multiple outputs of different resolutions.
The ADV8005 can accept OSD information from an external OSD source on one of its inputs or 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 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 6-DAC SD/HD video encoder. The flexible multiplexing allows simultaneous output on the HDMI transmitters and HD formats on the HD DACs (for example, 1080p) with SD formats on the SD DACs (for example, 480i).
Both of the HDMI transmitters on the ADV8005 support 4k x 2k and all mandatory and many optional 3D video resolutions. Each transmitter also features a full CEC master and audio return channel receiver (ARC). The ADV8005 can receive up to six channels of I2S, S/PDIF, direct stream digital (DSD), and high bit rate (HBR) passed from either the Serial Video Rx or from the externally available audio input pins.
The six 12-bit NSV® video DACs allow for 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.
