The Video Encoder and Video Decoder EI3 Extender Boards, both EZ-Extender® products, are low cost platforms facilitating the evaluation of video processing on an Analog Devices Embedded Processor via Analog Devices’ EZ-Board development hardware and the CrossCore® Embedded Studio software development environment.
The encoder has two video output devices. The first is the Analog Devices ADV7511, an HDMI transmitter for home entertainment products such as gaming consoles, PCs, DVD payers and recorders, digital set top boxes and A/V receivers. The second is the Analog Devices ADV7341, an encoder for DVD recorders and players and HD Blu-ray DVD players.
The decoder employs the Analog Devices ADV7842, a device for AVR video receivers, LCD/DLP front projectors, HDTV STBs with PVR, projectors and advanced TVs such as PDP HDTVs, LCD TVs, LCD/DLP rear projection HDTVs, CRT TVs LCoS HDTVs.
These EZ-Extenders connect with embedded processor EZ-Boards that support the Expansion Interface 3 (EI3) specification. This new interface facilitates more available signals on the interface connectors and a reduction in size over the previous EI2 specification. Software examples are provided to demonstrate the functionality of the devices on the Extender.

高性能HDMI发送器(ADV7511)
The ADV7511 is a 225 MHz high-definition multimedia interface (HDMI) transmitter, which is ideal for home entertainment products including DVD players/receivers, digital set top boxes, A/V receivers, gaming consoles and PCs.
The digital video interface contains an HDMI v1.4 and a DVI v1.0 compatible transmitter and supports all HDTV formats (including 1080p with 12-bit Deep Color). The ADV7511 supports the HDMI v1.4 specific features, HEAC (ARC), and 3D video. In addition, the ADV7511 supports x.v.Color, high bit rate audio and programmable AVI Info Frames features. With the inclusion of HDCP, the ADV7511 allows the secure transmission of protected content as specified by the HDCP v1.4 protocol.
The ADV7511 high-performance HDMI transmitter with ARC connects to the PPI, SPORT, TWI and GPIO of the processor. This device supports up to 1080p.
The ADV7511 can be configured to generate an interrupt based on various events. The TWI port is used for communication between the transmitter and processor. The PPI is used for transmitting video data.
The SPORT is used for transmitting audio data. An interrupt signal from the transmitter is connected to a GPIO signal on the processor.
多格式视频编码器(ADV7431)
The ADV7341 is a high speed, digital-to-analog video encoder. Six high speed, NSV, 3.3V, 12-bit video DACs provide support for composite (CVBS), S-Video (Y-C), and component (YPrPb/RGB) analog outputs in standard definition (SD), enhanced definition (ED), or high definition (HD) video formats.
The ADV7341 has a 30-bit pixel input port that can be configured in a variety of ways. SD video formats are supported over an SDR interface and ED/HD video formats are supported over SDR and DDR interfaces.
Pixel data can be supplied in either the YCrCb or RGB color space.
The part also supports embedded EAV/SAV timing codes, external video synchronization signals, and I2C communication protocol.
In addition, simultaneous SD and ED/HD input and output are supported.Full-drive DACs ensure that external output buffering is not required, while 216 MHz (SD and ED) and 297 MHz (HD) oversampling ensures that external output filtering is not required.
The ADV7341 multi-format video encoder connects to the PPI and TWI of the processor. This device supports up to 1080i/720p.
The TWI port is used for communications between the encoder and processor.
The PPI is used for transmitting video data.
