Abstract: An apparatus, medium, and method for displaying the downloading progress of data on an auxiliary display window when software is downloaded into a digital broadcast receiver (e.g., a set-top box). The apparatus for displaying the downloading progress of data includes a reconstruction unit, which receives broadcast signals from a broadcasting station and reconstructs data from the received broadcast signals, a processing unit, which calculates the downloading progress of the reconstructed data, an auxiliary display unit, which displays the calculation result obtained by the processing unit, and a control unit, which determines whether software to-be-downloaded is included in the reconstructed data, switches a current screen mode of the auxiliary display unit to a download mode if the software is included in the reconstructed data, and controls the auxiliary display unit to display the calculation result obtained by the processing unit.

Abstract: The system for receiving broadcast digital data (in particular pay television services) comprises a master digital terminal (1), and at least one slave digital terminal (2) connected to the master terminal by a link (3) and able to receive protected digital data. The slave digital terminal can access the protected data only if information necessary for accessing the data and received by the master digital terminal is sent by way of link (3) to the slave digital terminal within a predetermined deadline. This information is in particular access entitlements to television services or keys for descrambling the service.

Abstract: A terminal can play back song or video information in real time without downloading it, and thus restrictions on the hardware of the terminal are reduced and a large amount of music can be listened to anytime and anywhere. Also, the user can listen to music more cheaply than if it was downloaded, and copyright problems are reduced. Further, the terminal is charged based on the playback time or the amount of information. Accordingly, when the user stops playback because he or she does not like a song, the price is less than it is when the user listens to the song to the end, and thus the user can feel free to use this service.

Abstract: A request to transfer a consumer electronics (CE) application from a consumer electronics device to a TV device is received at the TV device. The CE application is received from the consumer electronics device. Application state information associated with the CE application is received from the consumer electronics device. The CE application and the application state information are stored to a memory. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Abstract: A continuous selection graph can be displayed as a graphical user interface, where the continuous selection graph includes a similarity continuum to indicate media content that is progressively similar, and includes an axis of identifying criteria for the media content. The axis of identifying criteria for the media content associates the media content along the similarity continuum, where the axis of identifying criteria is displayed perpendicular to the similarity continuum.

Abstract: Disclosed is a system for selective modification of transport data for enhanced video content. Video transport data is received in a video signal or an external source and a configurable processor uses criteria to selectively modify units of the video transport data. Disclosed criteria included a rule based pattern matching/replacement as well as criteria for denial, acceptance, or modification of particular units of video transport data. The modified video transport data stream created by the processor can be re-encoded in the video signal and provided to an external monitor.

Abstract: An anti-piracy system introduces distortion into a recorded image, while maintaining a high quality projected image. The video source material includes modulated entities for providing artifacts incompatible with the content of the video source material and selectively deliverable information that the projection system uses to demodulate the entities. A projector receives the information about the modulated entity and corrects, or demodulates, the entity. The projection system also imposes a recording device dependent interference on the projected images.

Abstract: The method comprises three stages. In the first stage, randomly selected point representations are stored in variables. In the second stage, a right-to-left loop is executed that modifies the variable values in dependency of a multiplier. In the last stage, the result is calculated from the modified variable values.

Abstract: A server stores original data without a water-mark. When a user at a terminal apparatus connected with the server requests the server to display the original data on a display of the terminal apparatus, the server transforms the original data into an image data. Then the server adds a water-mark to the image data and transmits the image data with the water-mark to the terminal apparatus.

Abstract: Methods and apparatus for enabling a Pervasive Authentication Domain. A Pervasive Authentication Domain allows many registered Pervasive Devices to obtain authentication credentials from a single Personal Authentication Gateway and to use these credentials on behalf of users to enable additional capabilities for the devices. It provides an arrangement for a user to store credentials in one device (the Personal Authentication Gateway), and then make use of those credentials from many authorized Pervasive Devices without re-entering the credentials. It provides a convenient way for a user to share credentials among many devices, particularly when it is not convenient to enter credentials as in a smart wristwatch environment. It further provides an arrangement for disabling access to credentials to devices that appear to be far from the Personal Authentication Gateway as measured by metrics such as communications signal strengths.

Abstract: An intrusion detection system (IDS) comprises a network processor (NP) coupled to a memory unit for storing programs and data. The NP is also coupled to one or more parallel pattern detection engines (PPDE) which provide high speed parallel detection of patterns in an input data stream. Each PPDE comprises many processing units (PUs) each designed to store intrusion signatures as a sequence of data with selected operation codes. The PUs have configuration registers for selecting modes of pattern recognition. Each PU compares a byte at each clock cycle. If a sequence of bytes from the input pattern match a stored pattern, the identification of the PU detecting the pattern is outputted with any applicable comparison data. By storing intrusion signatures in many parallel PUs, the IDS can process network data at the NP processing speed. PUs may be cascaded to increase intrusion coverage or to detect long intrusion signatures.

Abstract: A method, apparatus, and computer program product are described for asserting physical presence in a trusted computing environment included within a data processing system. The trusted computing environment includes a trusted platform module (TPM). The data processing system is coupled to a hardware management console. The trusted platform module determines whether the hardware management console is a trusted entity. The trusted platform module also determines whether the hardware management console has knowledge of a secret key that is possessed by the TPM. If the TPM determines that the hardware management console is a trusted entity and has knowledge of the secret key, the TPM determines that physical presence has been asserted.

Abstract: A method and system for detecting real-time system file intrusions in a user computer that is coupled to an administrator computer and includes an operating system and system files. At a boot time of the user computer, an application program interface (API) of the operating system receives a list of vital system files that consists of at least two directory files. At the boot time, one of more daemons are launched, after which the API detects one or more system calls made to one or more vital system files. The API raises an automatic interrupt ‘I’ command that awakens a daemon from a sleep mode. The awakened daemon catches the interrupt ‘I’ command and sends an alert message to the administrator computer to alert the administrator computer of the detecting of the system call made to the one or more vital system files.
