Abstract: A method, computer readable medium, and system for advertisement and content distribution are provided. Supplementary content is synchronized with advertisement slots, or commercial intervals, of a program stream and distributed via separate multicast group addresses. The program content is distributed via an alternative multicast group address during commercial intervals. Ports associated with respective users are mapped or otherwise associated with multiple multicast group addresses in a forwarding table thereby allowing distribution of supplementary content, or alternatively the program content, during commercial intervals.

Abstract: A method is provided for enabling rapid media stream channel changes in conjunction with increasing network resource utilization efficiency. A media stream is multicast for reception by a plurality of requesting decoders. The media stream includes packets containing groups of pictures (GOPs), which are stored in a buffer of an access node. At least a portion of the packets are unicast from the access node for reception by a new requesting decoder in response to receiving from the new requesting decoder a request for reception designating a media stream identifier corresponding to the media stream. Thereafter, the media stream is multicast to the new decoder after bringing packet transmission of the unicast media stream into alignment with packet transmission of the multicast media stream.

Abstract: A broadband fiber optic communication system conveys telecommunication messages over a fiber optic link between a master site and one or more remote sites. The remote sites are coupled over an unshielded twisted pair-configured, communication link to an optical network unit, which is ported to the fiber optic link. In order to convey broadband information signals that have been downlinked, from the master site to the optical network unit, to the remote sites, and to provide for return messages from the remote sites, a point-to-multi-point communication scheme is provided. Pursuant to this scheme, an upstream transceiver in the optical interface unit transmits STS-1 frames, which contain broadband information signals, such as asynchronous transfer mode (ATM) data cells, intended for one or more remote sites, and a return time slot-representative control code associated with each destination remote site, over the communication link to the remote sites.

Abstract: A two-stage cell routing filter mechanism employs a customer premises associated flag bit field in ATM data cells being serially transmitted from a host digital terminal's data transport path through an optical fiber to a downstream optical network unit associated with a plurality of customer premises equipments. The first stage of the cell routing filter is comprised of a look-up table (LUT) and an associated comparator mechanism. The state of each bit of the flag field of an ATM cell preamble will indicate whether or not the ATM cell is intended for the customer premises equipment associated with the bit. A downstream optical network unit contains an associated set of ATM cell filters associated with customer premises equipment. Each customer equipment cell filter examines a given bit position in the flag field portion of each received ATM cell preamble, to see whether the flag field bit of the preamble of the received ATM cell is set to prescribed bit value (e.g.

Abstract: A fiber optic telecommunication system has master site linked to a plurality of subscriber interface sites by a single pair of optical fibers. Downlink messages are transmitted in a continuous TDM format over a first optical fiber from the master site to subscriber interface sites, and in a burst mode TDMA format over a second optical fiber from the subscriber interface sites to the master site. Each subscriber interface site is coupled to the optical fiber link by way of a multiple fan-out fiber coupling pedestal at a common location on the fiber pair. To prevent collisions between successive uplink bursts from the subscriber interface sites, a guard band separates successive uplink messages from one another. The guard band duration accommodates optical fiber transmission distance between the common location on the uplink optical fiber and the subscriber interface site whose differential optical fiber transmission distance from the common location is greatest.

Abstract: A composite color television signal codec combines modified folded, hybrid differential pulse code modulation (H-DPCM) encoding and band-limiting decimation and interpolation filters to enhance encoding resolution without a reduction in signal quality of the reconstructed signal. The codec encodes, at five bits per sample, an NTSC 4.2 MHz composite color video signal for transmission over a 44.736 Mb/s communication channel. As in a conventional (H-DPCM) encoding scheme, a digital code value that is associated with a previous (quantized) jth sample of the signal and the difference between that digital code value and a digital code value of an ith sample are combined to produce an output code value for the ith sample.
