US 2006/0184841 A1 · Integrated apparatus for multi-standard optical storage media

Abstract

An integrated apparatus for multi-standard optical media includes a compact disc/digital versatile disc (CD/DVD) processor, a high-definition DVD (HDDVD) processor and a Blu-ray disc (BD) processor; a memory unit connected to the CD/DVD processor, the HDDVD processor and the BD processor to provide a storage resource; and a shared error correction code (ECC) engine for encoding or decoding the CD/DVD data stream, the HDDVD data stream and the BD data stream. Therein, the ECC engine further has a syndrome/parity generator to encode the data stream or to obtain the syndrome information from the data stream; and an erasure generator to obtain the possible error position information from the data stream. Thereby, the complexity and cost of the integrated apparatus can be reduced.
