A metrology device incorporates a programmable smart card. The smart card may be a Java programmable smart card and allows the metrology device to access Java applications and resources while still retaining independent control over its metrological functions. A smart card interface allows the smart card and metrological device to communicate with each other using the ISO 7816 protocol. The smart card may be external to the metrology device, or it may be fixedly installed in the metrology device...

Methods and apparatus for implementing a reduced cost HDTV/SDTV video decoder are disclosed. The described joint video decoder is capable of decoding HDTV pictures at approximately the resolution of standard definition television pictures and can be used to decode HDTV and/or SDTV pictures. The described video decoder may be used as part of a picture-in-picture decoder circuit for providing picture-in-picture capability without providing multiple full resolution video decoders. The reduction in ...

Automated methods and apparatus for synchronizing audio and text data, e.g., in the form of electronic files, representing audio and text expressions of the same work or information are described. A statistical language model is generated from the text data. A speech recognition operation is then performed on the audio data using the generated language model and a speaker independent acoustic model. Silence is modeled as a word which can be recognized. The speech recognition operation produces a...

A sample stream having a fixed sampling rate, representing a filtered version of an input symbol stream is produced by a pulse shaping and resampling device of the present invention. The pulse shaping/resampling device can be used as part of a digital modulator. In order to accommodate a wide range of ("variable") input baud rates, as part of the pulse shaping/resampling device, a filter having an integral upsampling ratio is used, followed by a resampler circuit having a finely adjustable resam...

Automated methods and apparatus for synchronizing audio and text data, e.g., in the form of electronic files, representing audio and text expressions of the same work or information are described. Also described are automated methods of detecting errors and other discrepancies between the audio and text versions of the same work. A speech recognition operation is performed on the audio data initially using a speaker independent acoustic model. The recognized text in addition to audio time stamps...

Methods and apparatus for automatically generating a set partition adjustment renormalization rate (SPARR) threshold used to determine correct or incorrect set partition synchronization in a trellis decoder as a function of a renormalization rate are described. The invention makes use of the inventor's observation that when the system is properly synchronized, the rate of growth of cumulative error sums closely corresponds to an accumulation of minimum set partition errors. In accordance with th...

Methods and apparatus for reducing the total amount of memory required to implement a video decoder and to perform a scan conversion operation on decoded video are described. In accordance with the present invention this is accomplished by having an interlaced to progressive (I-P) conversion circuit utilize the same frame memory used to decode the images upon which a conversion operation is performed. In this manner, the images, e.g., frames, which are buffered in the decoder are utilized by bot...

Methods and apparatus for providing speech recognition capability to callers in a cost efficient manner as part of one or more telephone services are described. Multiple speech recognition units with differing capabilities and therefore implementation costs are provided. Calls are assigned to speech recognition circuits throughout a call based on a signal such as a service type identifier indicating the type of service to be provided to the caller. During different phases of a call different spe...

A receiver arranged to receive and store broadcast data transported by elementary stream of a multiplexed and modulated digital television signal in a rewritable memory during a low power consumption mode for later recall by a user of the receiver. For recall, the receiver is fully energized, and the receiver is further arranged to transfer the broadcast data stored in the rewritable memory to a receiver storage device for further processing of the data under control of the user.
