Latest Patents

Shaw holds a patent for a "DVD data descrambler for host interface and MPEG interface." This invention provides a descrambler within a DVD controller that allows for real-time descrambling of DVD data from the DVD buffer. The built-in descrambler enables the controller to interface with a Host Adapter or MPEG II decoder. The descrambling circuit reads four bits of an identifier portion of each sector, which are used to access a look-up table in the descrambler for retrieving a 15-bit seed. This seed generates a descrambling pattern that, when XORed with scrambled data, descrambles the data on a byte-by-byte basis. The descrambling pattern is generated on a flash basis, allowing for efficient processing.
