    Abstract: The present embodiments provide methods for writing content to a media that comprise retrieving a first portion of a key structure from the media or a remote server, generating or receiving a second portion of the key structure based on the first portion of the key structure, encrypting content based at least on the second portion of the key structure, producing encrypted content, and writing the encrypted content onto the media. The present embodiments further provide recording media that include a digitally writable surface that is optically readable, a control area optionally comprising a pre-recorded set of keys defining a first portion of a key structure, and a data portion that records non-pre-recorded content protected according to a second portion of the key structure generated according to at least a portion of the first portion of the key structure.

    Abstract: A source image is encoded into a base layer and an enhancement layer. The base layer represents a standard definition portion of the source image and the enhancement layer represents a high-resolution portion of the source image. The base layer is stored on a first data storage track of a storage medium, such as a DVD, and the enhancement layer is stored on a second data storage track of the storage medium. The first data storage track may be a default camera angle track and then second data storage track may be a second camera angle track. The data is formatted such that a standard definition device will not read the enhancement layer data. A high-resolution decoding system decodes the base layer and the enhancement layer simultaneously to generate a high-resolution image.

    Abstract: A process for the production of syn gas (hydrogen and carbon monoxide) by reaction at high temperature between low molecular weight hydrocarbons, steam and oxygen in an impurities-containing refractory lined reaction zone. The lined reaction zone is pretreated with steam, or with steam and a reducing gas, e.g. a mixture of steam and hydrogen to leach out, react with, and transport the impurities, i.e., the reaction products of silica, or silica plus phosphorus or sulfur, or silica plus phosphorus and sulfur, from the reaction zone. Steam alone may be used to leach out, convert the silica to gaseous silicic acid, and remove same from the reaction zone; and then the hydrocarbons, steam and oxygen feeds are introduced into the reaction zone to produce syn gas.

    Abstract: A checkout counter having an optical scanning unit located therein and includes a surface portion comprising a scale apparatus which includes a transparent portion enabling scanning beams projected by the optical scanner unit to be transmitted through the scale apparatus for reading a coded label on a merchandise item positioned on the scale apparatus. The scale apparatus generates data signals representing the weight of the merchandise item which are then transmitted to a processor means which also receives data signals from the scanning unit identifying the merchandise item. The processor means will generate the price of the merchandise item using the data signals received. The price of the merchandise item is then displayed on a display unit and printed by a printing unit on a customer's receipt.
