- Frequently Asked QuestionThe compression rate is not defined in the JPEG2000 ISO/IEC15444-1 standard which is implemented on the ADV202/212. Any compression rate can be programmed with the ADV202/212 encode parameters. The part can be configured to provide a fixed compression rate with a variance of +5% of the programmed value, down to -100% of the programmed value. The compression rate is programmed with the RCType and RCVal encode parameters [refer to Programming Guide].
- Frequently Asked QuestionThe ADV202's latency is generally 1.5 fields in encode or decode mode. If frames are input, the the latency is in frames. ADI does not provide exact specification of latency, since it depends on a lot of factors which would make an exact specification difficult. Complexity of input image, # of wavelet transform levels, choice of wavelet filters, choice of output format will all effect latency but nevertheless it will be kept in the …
- Frequently Asked QuestionGenerally tiles can be merged on boundaries without artifacts. ADI provides a tile simulation software at: JPEG200 Eval Software Allows you to evaluate tile artifacts.
- Frequently Asked QuestionYes. The ADV202/212 compressed output, if .j2c or jp2 format, is fully compatible to the ISO/IEC 15444-1 JPEG2000 standard. Note, the ADV202/212 will insert a 16-byte header at the start of each codestream. This header has to be removed in order for other JPEG2000 codecs to recognize the codestream correctly. Commonly used with the ADV202/212, Kakadu is a free of charge software codec from www.kakadusoftware.com
- Frequently Asked Question1. ADV202/212 ASD P160 EB is an ADV202/ADV212 daugther card designed for a Memec Xilinx Spartan 3SXLC motherboard. Input: analog NTSC or PAL in CVBS or S-Video format Output: analog NTSC or PAL in CVBS or S-Video format The boards can be used in a stand-alone application. In this case modes are controlled over DIP switches. In PC control mode access to registers, parameter settings is possible. The board is …
- Frequently Asked QuestionMultilayer codestream means, that the JPEG2000 output stream contains several layers of which each layer contains data compressed at a different compression ratio. The number of layers can be programmed with the ADV202/212. On the decoding side it is then possible to extract a particular layer only. The data has to be encoded in Multilayer mode. To do this, the JPEG2000 parameter RCTYPE is set to Multi-layered Target Size or Multi-layered Target …
- Frequently Asked QuestionIf the image data is monochrome, It is required to tile the input into 16 1K x 1K tiles before compression and send them sequentially to the ADV202/212. Considering the HDATA data input rate limitations, this would allow an input rate of approx. 40 images/sec. For color images the images would have to be tiled further to stay under the maximum image size limit of 1.048 Msamples/image. A recommended configuration for …
- Frequently Asked QuestionYes. There are two methods to input raw image data to the ADV202: Over the VDATA bus using Raw Video Mode. This requires a synchronized pixel clock [Vclk] and HVF inputs along with the pixel data. HVF inputs are used in conjunction with the dimension register settings and define the image dimensions to be captured. Generally no horizontal or vertical blanking regions are expected with the input data. Refer to the ADV202/212 Programming Guide …
