The manufacturer of the equipment generating the stream said later they were using proprietary algorithm based on J2K (probably some tweak after ADV202 processing). The issue is closed then, the decompression algorithm is also proprietary.
When I use ADV202 for JEPG200 compression, the bus size is 32-bit, sometime the
output is a fixed four-byte data like 0xff77be7, 0xff77fbe2, 0xff7ffbe3. Can
you figure out the possible reason for that?
Sometimes the output is a fixed four-byte data…

Generally, i think it is 8x8,. 16x16.
(ex) image size is 2000 x 3000. Can ADV202 encode this image correctly ?

We wanna to use adv202 jdate output to encode still image . But this mode is not compatible with the raw mode. So сan we use the same input and settings for the frame to get the same result?
I am tring to encode mono-chrome image (640x480 pixels) when input is RAW mode and output is single transfer DREQ/ACK DMA mode in ADV202.I have 2 problems.
1. VRDY becomes '0' at 305718bytes when i input pixel until 640x480=307200bytes Is the…
Hi. I have a legacy design which uses the ADV202. This is now NRND and the web-site for the ADV202 specifies the ADV212 as a direct replacement. I imagine the footprint and functionality are equivalent (as stated) but if I swap to the ADV212 will the…

Compressed data may not be output by the signal to be supplied to the
Greetings.Would you mind to help me. Is there a timeline for the "DREQ / DACK read test" from page 6, c.17, AN799_TestModes.pdf for ADV202?I.e. should I expect from ADV to send only one DREQ pulse or a pulse train?
i want to interface ADV7611 output signal to ADV202 for JPEG2000 compression. ADV7611 has multiplexed VSYNC/FIELD/ALSB pin, but ADV202 requires separate VSYNC and FIELD signals. how to interface these signal physically. pl. advice
I'm currently using the ADV202 to encode images. I'm using tha Kakadu software for playing bak the encoded images. My input image contains Chinese characters and while playing back the image, the characters look blurry. Is there any suggested…
