  This document provides a technical description of the codec proposed by EPFL
to the JPEG DNA Call for Proposals. The codec we refer to as V-DNA for its
versatility, enables the encoding of raw images and already compressed JPEG 1
bitstreams, but the underlying algorithm could be used to encode and transcode
any kind of data. The codec is composed of two main modules: the image
compression module, handled by the state-of-the-art JPEG XL codec, and the DNA
encoding module, implemented using a modified Raptor Code implementation
following the RU10 (Raptor Unsystematic) description. The code for encoding and
decoding, as well as the objective metrics results, plots and biochemical
constraints analysis are available on ISO Documents system with document number
WG1M101013-ICQ-EPFL submission to the JPEG DNA CfP.
