In an embodiment a single user authentication event, performed between a trusted path hardware module and a service provider via an out of band communication, can enable a user to transparently access multiple service providers using strong credentials that are specific to each service provider. The authentication event may be based on multifactor authentication that is indicative of a user's actual physical presence. Thus, for example, a user would not need to enter a different retinal scan to gain access to each of the service providers. Other embodiments are described herein.

Out-of-band remote authentication

Out-of band remote authentication

A method and apparatus for transcoding a digital video signal is described. A first set of bits encoded in a first encoding format are received. The first set of bits are decoded to discrete cosine transform (DCT) coefficients. The DCT coefficients are transformed into an intermediate exchange format. The transformed DCT coefficients are encoded using a second encoding format.

Method and apparatus for transcoding digital video signals

Digital video (DV) formatted image streams may be converted into an intermediate format having a lower resolution than the original image streams. A user may then edit the intermediate formatted image streams to generate a sequence of edit commands. The edit commands may then be processed to generate an output image stream based on the original image streams. The output image stream may be in any desired format, including DV format. The sequence of edit commands may also be processed to generate a preview image stream in the intermediate format.

Method and apparatus to edit digital video data

A method and apparatus for run length encoding video data for transform based coders. The video data is separated into blocks of pixels. The pixel values are transformed to another set of values which can be represented with less data. The transformed values are quantized by generating a quantized magnitude and sign for multiple transformed values at a time, while removing branch misprediction errors during the quanitizing process. The quantized values are run length encoded by removing branch misprediction errors during the encoding process.
