Abstract: A system for transmitting messages and multi-media presentations to a multi-media receiver (114). The system includes a multi-media messaging terminal (106) which has a controller (216) for the preparation and transmission of a multi-media presentation, composed of multi-media files. The multi-media files include user programmed text events (1258), graphics events (1260), audio events (1254) and multi-media commands (1256). The controller (216) is coupled to a memory, for storing the user programmed text events, graphics events, audio events and multi-media commands, and a multi-media interface (208).

Abstract: A communication system (100) providing analog message re-transmission on demand comprises a base station (114) and at least one portable communication transceiver (118). The base station (114) transmits an address (414) identifying the portable communication transceiver (118) to which a voice message is directed, and a session number (415) modulated in a first modulation format and a compressed analog message (418) representing the voice message modulated in a second modulation format. When the signal quality of the voice message played back in the portable communication transceiver (118) is perceived by the user to be unintelligible, the user can receive from the base station (114) a re-transmission of the compressed analog message (418) by generating a request for re-transmission of the compressed analog message (418).

Abstract: A communication transceiver (510) having a receiver (704), a controller (714) and a transmitter (710), is used for generating an unscheduled acknowledge back response. The receiver (704) receives an address and a color code identifying the cell transmitter (506) transmitting the address during a first scheduled time interval (212). The controller (714) selects, in accordance with the address received, a reserved response time slot from a predetermined number of reserved response time slots occurring during a second scheduled time interval. The transmitter (710) then transmits the unscheduled acknowledge back response during the reserved response time slot (224) selected.

Abstract: A method and apparatus is provided for a low bit rate speech transmission. Speech spectral parameter vectors are generated from a voice message and stored in a sequence of speech spectral parameter vectors within a speech spectral parameter matrix. A first index identifying a first speech parameter template corresponding to a first speech spectral parameter vector of the sequence of speech spectral parameter vectors is transmitted. A subsequent speech spectral parameter vector of the sequence is selected and a subsequent speech parameter template is determined having a subsequent index. One or more intervening interpolated speech parameter templates are interpolated between the first speech parameter template and the subsequent speech parameter template. The one or more intervening speech spectral parameter vectors are compared to the corresponding one or more intervening interpolated speech parameter templates to derive a distance.

Abstract: An apparatus and method for updating upper and lower thresholds in peak and valley systems. The apparatus includes comparators which determine which peaks or valleys are eligible for use in the calculation of upper or lower threshold levels. The comparators output the eligible peaks and valleys into statistical blocks that calculate the mean of the peaks and valleys as well as the deviation over a predetermined number of samples. Additional comparators compare either the mean deviation, standard deviation, or variance of the eligible peaks and valleys to predetermined deviation thresholds to determine whether the mean peak or mean valley should be used to calculate update thresholds. The apparatus further includes memory elements that store the mean peak or mean valley values used in the calculation of upper or lower thresholds.
