👉 DVD engineering encompasses the technical processes involved in creating, encoding, and reading digital data on DVDs to ensure high-quality playback. This includes the design of the physical disc, such as its material composition and layer structure, which determines storage capacity and durability. Data encoding involves converting digital video and audio information into a format suitable for the DVD's optical media, typically using standards like MPEG-2 for video and PCM for audio. The engineering also includes the development of laser technology, such as red or blue lasers, to read and write data accurately onto the disc. Error correction algorithms are implemented to maintain data integrity, and the design of the DVD's tracking system ensures that the laser can precisely follow the data tracks. Overall, DVD engineering aims to balance storage capacity, playback quality, and durability while adhering to industry standards.
