In accordance with an embodiment of the present invention, a client device is protected against the execution of unauthorized software. The client includes a code authentication process that verifies the integrity of executable code, by generating and comparing a first hash value of the executable code with a known hash value of the original code. Furthermore, during boot-up, the client initializes a CPU exception vector table with one or more vector table entries. One or more, or all, of the vector table entries direct the CPU to execute the code authentication process prior to executing an event handler when an exception event occurs. Consequently, the code authentication process is virtually guaranteed to execute, thereby protecting against the execution of unauthorized code.

Method and system for protecting against the execution of unauthorized software

A multimedia signal processing system allows a user to store selected programs while simultaneously watching or reviewing another. The system includes an input section and an output section. Across all configurations, the output section remains substantially the same, while the input section varies according to the signal type and the source. The system receives a digital stream and simultaneously processes the digital stream for display and stores the digital stream on at least one storage device. The system further simultaneously processes a previously recorded digital stream for display while processing the digital stream for display.

A multimedia mobile personalization system provides a remote control that detects a user's electronic tag, e.g. an RFID tag. The remote control notifies a multimedia device of the user's identity. The multimedia devices tailors it operations to the user's preferences stored locally. Multimedia content such as broadcast or recorded television programs, music play lists, and the like could be sorted, displayed, or restricted, depending on the user identifier.

A multimedia time warping system allows a user to store selected multimedia data streams while the user is simultaneously watching or reviewing other multimedia data. Data streams are converted to digital streams for internal transfer and manipulation. A parser and event buffer decouple the CPU from having to parse the digital stream. Video segments are stored on a storage device and when data is requested for display, its video segments are extracted from the storage device and sent to a decoder that converts them into display output signals and delivers the display output signals to a display.

A digital security surveillance system allows a user to store selected security surveillance feeds while the user is simultaneously watching or reviewing another feed. User control commands are accepted and sent through the system. The system parses the resulting digital stream and generates identifying information associated with at least one video segment of the digital stream. The video segments are stored on a storage device. When a security surveillance feed is requested for display, a corresponding stored digital stream is found and its video segments are extracted from the storage device and sent to a decoder that converts the digital stream into display output signals. The security surveillance feeds can be simultaneously sent to an external storage device such as a DVD recorder or VCR.

A multimedia mobile personalization system allows a user to record and play multimedia content on a set top box at a location other than his home using the user's preferences from his home DVR.

A multimedia signal processing system utilizes an easily manipulated, low-cost storage and display system that allows the user to view a television program and instantly review previous scenes within the program. The invention also allows the user to store selected programs while simultaneously watching or reviewing another. A versatile system architecture enables providing the invention in multiple configurations, each adapted to receive input signals from a different source. At the highest level, the system includes an input section and an output section. Across all configurations, the output section remains substantially the same, while the input section varies according to the signal type and the source. Thus, several configurations are provided, each one requiring only minor system board modifications. The system architecture thus simplifies the design and manufacturing challenge presented by producing units to serve different markets, such as digital satellite, digital cable and analog cable.

Multimedia signal processing system

A digital video recorder (DVR) system with an integrated DVD recording device accepts TV input streams in a multitude of forms. Analog TV streams are converted to an MPEG formatted stream for internal transfer and manipulation, while pre-formatted MPEG streams are extracted from the digital TV signal and presented in a similar format. Indexes within the MPEG stream are determined and saved at predefined intervals and are stored on a hard disk along with the MPEG program material and used to create navigation packets when writing to a DVD inserted in an integrated DVD player/recorder. When a program is requested for display from the hard disk or the integrated DVD player/recorder, the program material are extracted from the appropriate source and reassembled into an MPEG stream which is sent to a decoder. The decoder converts the MPEG stream into TV output signals and delivers the TV output signals to a TV monitor. User control commands are accepted which affect the flow of the MPEG stream allowing the user to view stored programs with special functions: reverse, fast forward, play, pause, index, fast/slow reverse play, and fast/slow play. The user can select program material stored on the hard disk to be written to a DVD and can also select program material stored on a DVD to be transferred to the hard disk.

Digital video recorder system with an integrated DVD recording device

A system and method for providing multiple audio streams for a video over a network such as the Internet. The system comprises a server that includes an encryption unit and a slicing unit, a plurality of boxes, and an ordering box. The server encodes multiple audio streams and a single video to be sliced into segments. The sliced segments of multiple audio streams and the single video are seeded to a number of the plurality of boxes. This may be repeated for other videos with multiple streams. When the ordering box makes a request for a single video with a single audio, then the number of boxes with segments of the requested video and multiple audio streams, filters and sends the requested video and requested single audio stream to the ordering box. Similarly, multiple closed caption streams can be handled and provided like the audio streams.
