Processes are disclosed for retrieving and loading configuration code in pre-boot and runtime environments. Additional embodiments relate to XML files containing EBC images, processing systems that use EBC images from XML documents as configuration code, and processing system that provide XML documents with EBC images to other processing systems. Other embodiments are described and claimed.

Abstract: A method involves operations for executing source code instructions expressed in a programming language. The operations comprise receiving a series of source code instructions expressed in a programming language, wherein at least one of the source code instructions includes a command and one or more arguments. In response to receiving the source code instruction, at least part of a stack-based execution stream is built. The stack-based execution stream is also executed. The operation of building at least part of a stack-based execution stream involves storing the instruction's argument on a stack, determining an address for an object code routine corresponding to the instruction's command, and storing the address for said object code routine on the stack. Other embodiments are described and claimed.

Abstract: Protected content distribution is accomplished by a first entity generating a set of asymmetric key pairs, creating a plurality of sets of private keys by selecting a combination of private keys from the set of asymmetric key pairs for each created set, and distributing the sets of private keys to playback devices. A second entity produces protected content including encrypted content and a public key media key block, encrypts a symmetric content key with each public key in the set of asymmetric key pairs to form the public key media key block and encrypts a content title with the symmetric content key to form the encrypted content. A playback device stores one set of private keys, receives the protected content, and decrypts and plays the content title stored in the protected content when a selected one of the set of private keys stored by the playback device successfully decrypts the encrypted symmetric content key stored in the public key media key block of the received protected content.

In one embodiment, a recording device having a first watermark detection component of a first sensitivity for detecting the watermark in digital content, interoperates with a playback device having a second watermark detection component of a second sensitivity for detecting the watermark in a digital content recording made by the recording device; such that the first sensitivity is more sensitive than the second sensitivity.

Abstract: A method of delivering input from a device's remote control to a Java™ application uses asynchronous method invocation in a processing device. The input from the remote control is captured in system-specific (native) code and delivered to a Java™ application asynchronously. This is achieved by calling an event method in the Java™ application in response to the received input signals. The event method is then executed to transfer the input signals from the remote control.

The pen also includes a higher frequency burst transmitter useful to generate a time reference, and to transmit the pressure information. The computer packetizes the shape, velocity, acceleration, and pressure data with a time stamp and an IP address or phone number, encrypts the packet and sends it to a host computer for authentication.
