Abstract: A single-wire communication bus couples a transmitting device to a UART in a receiving device. Flow control circuitry in the UART fills a transmit memory buffer with remote data. The UART supplies a remote start bit onto the single-wire bus for each byte of remote data written into the transmit memory buffer. After detecting a remote start bit on the single-wire bus, the transmitting device supplies initial data bits and a stop bit, which together form an RS232 character. Data flow is controlled when the UART supplies a subsequent remote start bit only after data has been read out of the UART freeing up bytes in a receive memory buffer. After the transmitting device detects the subsequent remote start bit, the transmitting device supplies subsequent data bits onto the single-wire bus. In another embodiment, flow control circuitry functionality is performed by flow control code in the receiving device operating system.

The contents of each respective channel of a multi-channel voice playout buffer are encapsulated so as to prepend a four byte ATM header, a HEC byte, and a four byte AAL2 header to a forty-four byte voice channel field to realize a standard fifty-three byte ATM cell. Within the AAL2 header, a channel identification byte (CID) provides selective mapping to timeslots of a TDM frame, to accommodate variations among different vendor equipments. The next to last bit of the last byte of the ATM header is used as an interrupt to the network processor. Only the highest voice channel asserts this next to last bit as an interrupt bit.

Abstract: The present invention generally relates to the transmission of digital data, and more particularly, to the transmission of digital data in a satellite digital audio radio (“SDAR”) system. In the SDAR system, there may be different types of required services. Some of these services may be considered high priority and others may be of a lower priority. Current SDAR systems have the same performance on all user data. Therefore, there is a need to vary the performance of different services. The present invention provides a method and apparatus for optimizing the throughput (i.e. information) in a digital transmission system by transmitting the different services with different performance levels. The present invention addresses the need in the art to vary the performance of different services (i.e., levels of data). Because the performance of the primary level of data will not be equal to the performance of the secondary level of data, the primary level will need to be further protected.

Abstract: A time zone start time point calculating unit calculates a time zone to be set in a VOBU in accordance with audio bit rate. A time zone comparing unit compares a time point at which an audio pack is to be multiplexed with the time zone calculated by the time zone start time point calculating unit. A flag setting unit sets whether the audio pack is to be completed or not in accordance with the result of comparison by the time zone comparing unit. Therefore, a completing process takes place before a VOBU boundary, and a completed PCK will not be generated immediately after the VOBU boundary. Thus, generation of a buffer overflow can be prevented.

Abstract: A digital Vestigial Sideband (VSB) transmission system and enhanced data multiplexing method are disclosed. When 1/2 enhanced data coded at a rate of 1/2 and 1/4 enhanced data at a rate of 1/4 are transmitted, timing jitter in Moving Picture Experts Group (MPEG) of Vestigial Sideband (VSB) receiver can be reduced and the size of input buffer in Moving Picture Experts Group (MPEG) decoder of the Vestigial Sideband (VSB) receiver can be reduced by multiplexing the 1/2 enhanced data packet and the 1/4 data packet at predetermined intervals. Multiplexing the 1/2 enhanced data packet and the 1/4 data packet by grouping increases the reception performance of the 1/4 enhanced data. Multiplexing the 1/2 enhanced data packet and the 1/4 data packet alternatively reduces the Moving Picture Experts Group (MPEG) timing jitter in the Vestigial Sideband (VSB) receiver and increases the reception performance of the 1/4 enhanced data.

Abstract: In the face of data loss on connections between a content source and a content consumer, additional connections therebetween are opened. These additional connections are preferably opened between the content source and a proxy disposed between the content source and the content consumer. The proxy may then seam together data streams received from the content source across the additional connections in a recording on a computer-readable medium. The seamed stream may be constructed by filling in information gaps in any of the data streams received from the content source with content derived from others of the data streams received from the content source. This derivation may be made on the basis of identifying characteristics (e.g., packet contents) of packets from each of the data streams received from the content source.

Abstract: A method and apparatus are disclosed for monitoring and signaling a path restoration using pre-computed restoration paths following a detected fault on a primary service path in a communications network. A fault occurring inside the restorable portion of a network in heterogeneous or multiple network environments can be distinguished from faults occurring outside the restorable network in accordance with the ANSI Tandem Connection Maintenance standard, T1.105.05-1994. Path restoration is activated only when a fault causing path failure occurs inside the restorable portion of the network. Each conforming node in the restorable portion of the network has the necessary monitoring, signaling and cross-connect functionality and databases to participate actively in real time restoration. Additional non-conforming network elements can be positioned between the restoration nodes without preventing path restoration.

Abstract: A communication system includes an optical transmitter which is differentially driven and an optical receiver that outputs a differential signal. The optical transmitter creates the differential drive signal from an input signal and delivers the differential drive signal to a laser. The differential drive signal is generated with a transformer and RF chokes for floating the laser above ground. The signal detected by the receiver is input as a differential signal to a transformer which then passes the signal through amplifiers and a filter. The optical communication system provides an increased spurious-free dynamic range which is well suited for RF signals and other analog signals.

Abstract: An asynchronous sample rate converter interpolates and filters a digital audio input signal to produce a filtered, up-sampled first signal. A FIFO memory receives the first signal and stores samples thereof at locations determined by a write address and presents stored samples from locations determined by a read address. The presented samples are passed through an interpolation and resampling circuit to produce a continuous-time signal which is re-sampled to produce a signal that is up-sampled relative to a desired output. That signal then is filtered and down-sampled to produce the output signal. Sample rate estimating circuitry computes a difference signal representative of a time at which a data sample of the audio input signal is received and a time at which a corresponding audio output sample is required, and address generation circuitry generates the read and write addresses.

Abstract: A single-wire communication bus couples a transmitting device to a UART in a receiving device. Flow control circuitry in the UART fills a transmit memory buffer with remote data. The UART supplies a remote start bit onto the single-wire bus for each byte of remote data written into the transmit memory buffer. After detecting a remote start bit on the single-wire bus, the transmitting device supplies initial data bits and a stop bit, which together form an RS232 character. Data flow is controlled when the UART supplies a subsequent remote start bit only after data has been read out of the UART freeing up bytes in a receive memory buffer. After the transmitting device detects the subsequent remote start bit, the transmitting device supplies subsequent data bits onto the single-wire bus. In another embodiment, flow control circuitry functionality is performed by flow control code in the receiving device operating system.
