摘要： A method and apparatus for communicating a real time media input over a network. The apparatus encodes the input into data packets having a number of frames ordered according to a first variable. A receiving device unpacks and buffers the unpacked data packets for playout according to a second variable. The receiving device generates utility parameters for evaluating a dynamic characteristic of the network that transports the data packets. The receiving device selects a preferred utility parameter and adjusts the first and second variable according to the selected utility parameter. The method includes encoding an analog input into data packets that are transported to a receiving device. The method also includes unpacking the data packets, buffering the unpacked data packets according to a second variable, and generating at least two utility parameters that represent a dynamic characteristic of a network. The method also includes selecting a preferred utility parameter and adjusting the first and the second variables according to the selected preferred utility parameter.

摘要： The present invention is embodied in a digital communication system where multiple media data sources are time multiplexed into a packetized data stream, each packet having an assigned priority and the packetized data stream transmitted in substantially the order of assigned priority. At both the transmit side, and the receive side, audio packets are given priority processing over video packets, which in turn have priority over text/graphics data packets. Continuous real time audio playback is maintained at the receiver by delaying the playback of received audio in a first in/first out (FIFO) buffer providing a delay at least equal to the predicted average packet delay for the communication system. Optionally, the average system delay is continuously monitored, and the audio playback delay time is adjusted accordingly. Audio playback is slowed or accelerated in order to shrink or grow the difference in time between the sender and receiver. In another aspect of the invention, a conference of three or more callers is created by broadcasting a common packetized data stream to all conference callers.

摘要： Transmission of signals over a communications channel. An output of a digital signal generator is analyzed over a sampling interval and a duration of first digital signals generated over the sampling interval is determined, wherein any difference between the sampling interval and the duration of first digital signals is a remainder of the sampling interval. In one embodiment, the first digital signals are assembled into a contiguous block and transmitted over the communications channel. Second digital signals are transmitted over the communications channel for a period substantially equal to the remainder of the sampling interval.

摘要： A multimedia distribution network combines the flexibility of digital video and digital networks with the low cost, high bandwidth, and isochronous capabilities of analog video distribution. At the heart of the network is a hybrid digital/analog multimedia hub, called a C-box, which provides connectivity to digital networks, both local area and wide area, with the necessary video compression and decompression, composition engines for multiple video streams and analog/digital conversions of the multiple video streams for connectivity to an analog video distribution network for delivery to end user workstations. The C-box receives multiple compressed digital video streams, decompresses the video streams, converts the decompressed video streams to analog, and delivers the converted analog signals to workstations via an analog cable television (CATV) network. The amount of video processing (e.g., compression and decompression) power required is proportional to the number of active video streams instead of the number of attached end user workstations. The analog channels over which the converted analog signals are transmitted are dynamically allocated, and once the analog signals have been transmitted to a requesting client terminal, the channels are released for reuse.
