    Abstract: THE PRESENT INVENTION DISCLOSES A VARIABLE RATE TRANSMISSION SYSTEM WHEREIN A PACKET OF VARIABLE RATE DATA (50) AT A DATA RATE IS TRANSMITTED ON A TRAFFIC CHANNEL IF THE CAPACITY OF SAID TRAFFIC CHANNEL IS GREATER THAN OR EQUAL TO SAID DATA RATE OF SAID PACKET AND WHEREIN A PACKET OF VARIABLE RATE DATA IS TRANSMITTED ON A TRAFFIC CHANNEL AND AT LEAST ONE OVERFLOW CHANNEL IF THE CAPACITY OF SAID TRAFFIC CHANNEL IS LESS THAN SAID DATA RATE. THE PRESENT INVENTION FURTHER DISCLOSES A RECEIVING SYSTEM FOR RECEIVING VARIABLE RATE DATA WHEREIN A RECEIVED PACKET OF VARIABLE RATE DATA IS RECEIVED ON A TRAFFIC CHANNEL IF THE CAPACITY OF SAID TRAFFIC CHANNEL IS GREATER THAN OR EQUAL TO A DATA RATE OF SAID PACKET AND WHEREIN A PACKET OF VARIABLE RATE DATA (50) IS RECEIVED ON A TRAFFIC CHANNEL AND AT LEAST ONE OVERFLOW CHANNEL IF THE CAPACITY OF SAID TRAFFIC CHANNEL IS LESS THAN SAID DATA RATE.FIG. 4, 5

    Abstract: A variable rate transmission system where a packet of variable is transmitted on a traffic channel if the capacity of the traffic channel is greater than or equal to the data rate of the packet. When the rate of the packet of variable rate data exceeds the capacity of the traffic channel, the packet is transmitted on a traffic channel and at least one overflow channel. Also described is a receiving system for receiving and reassembling the data transmitted on the traffic channel and at least one additional overflow channels.

    Abstract: LA PRESENTE INVENCION DESCRIBE UN SISTEMA DE TRANSMISION DE VELOCIDAD VARIABLE EN EL QUE UN PAQUETE DE DATOS A VELOCIDAD VARIABLE SE MODULA DE ACUERDO CON UNA SECUENCIA DEL CANAL DE TRAFICO SUMINISTRADA POR UN GENERADOR DE TRAFICO PN (63) SI LA CAPACIDAD DE DICHO CANAL DE TRAFICO ES MAS GRANDE O IGUAL A LA VELOCIDAD DEL PAQUETE DE DATOS. SI LA CAPACIDAD DEL CANAL DE TRAFICO ES INFERIOR A LA VELOCIDAD DE DATOS DEL PAQUETE, ENTONCES EL PAQUETE DE DATOS DE VELOCIDAD VARIABLE SE MODULA DE ACUERDO CON LA SECUENCIA DEL CANAL DE TRAFICO SUMINISTRADA POR EL GENERADOR DE TRAFICO PN (63) Y DE ACUERDO CON LA SECUENCIA DE AL MENOS UN CANAL DE DESBORDAMIENTO SUMINISTRADA POR EL GENERADOR DE CANAL DE DESBORDAMIENTO (65). LA PRESENTE INVENCION ADEMAS DESCRIBE UN SISTEMA DE RECEPCION PARA LA RECEPCION DE DATOS DE VELOCIDAD VARIABLE, EN EL QUE UN PAQUETE DE DATOS DE ESE TIPO ES DEMODULADO DE ACUERDO CON LA SECUENCIA DEL CANAL DE TRAFICO SUMINISTRADO POR UN GENERADOR PN (104) SI LA CAPACIDAD DEL CANAL ES SUPERIOR O IGUAL A LA VELOCIDAD DE LOS DATOS DE DICHO PAQUETE. SI LA CAPACIDAD DEL CANAL DE TRAFICO ES INFERIOR A LA VELOCIDAD DE TRANSMISION DE LOS DATOS DEL PAQUETE, ENTONCES EL PAQUETE RECIBIDO SE DEMODULA DE ACUERDO CON LA SECUENCIA DEL CANAL DE TRAFICO GENERADA POR EL GENERADOR DE TRAFICO PN (104) Y DE ACUERDO CON LA SECUENCIA DE AL MENOS UN CANAL DE DESBORDAMIENTO SUMINISTRADAS POR EL GENERADOR DE CANAL DE DESBORDAMIENTO.

    Abstract: Apparatus, systems and methods for using the selection of an appropriate parameter at decompression are disclosed. In particular, when adaptive block size discrete cosine transform compression is used to compress data, different combinations of sub-blocks can be generated. To decompress the different combinations of sub-blocks, the appropriate parameter is selected based on block size assignment information and the address of data in the data block.

    Abstract: An apparatus to determine a transform of a block of encoded data the block of encoded data comprising a plurality of data elements. An input register is configured to receive a predetermined quantity of data elements. At least one butterfly processor is coupled to the input register and is configured to perform at least one mathematical operation on selected pairs of data elements to produce an output of processed data elements. At least one intermediate register is coupled to the butterfly processor and configured to temporarily store the processed data. A feedback loop is coupled to the intermediate register and the butterfly processor, and where if enabled, is configured to transfer a first portion of processed data elements to the appropriate butterfly processor to perform additional mathematical operations and where if disabled, is configured to transfer a second portion of processed data elements to at least one holding register.
