摘要： Method and apparatus to determine the channel to which a TV tuner is tuned from a return loss ratio measurement circuit in a set top decoder. The method comprises generating a plurality of probe signals having frequencies spread throughput the TV channel band, preferably using harmonics of a zero order hold D/A converter. The return loss ratio of the reflected probe signals is then determined and stored as a signature for the TV channel and the signatures can subsequently be used along with new return loss ratio measurements to determine the TV channel to which a TV or VCR tuner is tuned.

摘要： A system for bidirectional communication of digital data between a central unit and a remote unit wherein the need for tracking loops in the central unit has been eliminated. The central unit transmitter generates a master carrier and a master clock signal which are used to transmit downstream data to the remote units. The remote units recover the master carrier and master clock and synchronize local oscillators in each remote unit to these master carrier and master clock signals to generate reference carrier and clock signals for use by the remote unit receiver. These reference carrier and clock signals are also used by the remote unit transmitters to transmit upstream data to the central unit. The central unit receiver detects the phase difference between the reference carrier and clock signals from the remote units periodically and adjusts the phase of the master carrier and master clock signals for use by the central unit receiver to receive the upstream data.

摘要： A process for grouping cable modems by type/modulation profile and/or throughput ability into different logical groups. Each logical group is commanded to transmit on an upstream which has a burst profile set to effectively use the throughput ability of the cable modem. Some species monitor initial ranging bursts and separate CMs with inadequate power onto a lower throughput upstream. Some species monitor post registration data transmissions for various factors and subdivide groups into subgroups of overperformers and underperformers.

摘要： Method and apparatus to carry out wideband DOCSIS both upstream and downstream in a point-to-multipoint environment of an HFC system using port trunking concepts. For the downstream, each CMTS has a frame distributor which distributes frames to various transmitters transmitting on downstream channels to be used to transmit downstream data simultaneously to a CM using wideband DOCSIS. The frame distributor adds sequence numbers in some embodiments to guarantee proper order of frames can be restored at the CM, and schedules transmissions according to quality of service considerations to meet guaranteed and committed portions of constant bit rate and variable bit rate flows. The CMTS sends and Extended Channel Enable (ECE) message to wideband capable CMs telling them which downstreams to enable. Each CM has a frame collector to which all frames received on various downstream channels are sent. The frame collector makes sure they are all there, puts them into the proper order and delivers them to a NI. Upstream wideband DOCSIS works the same way with a frame distributor in each CM and a frame collector in the CMTS. The CMTS receives bandwidth requests and controls upstream wideband DOCSIS transmissions by sending downstream UCD and MAP and ECE messages to the CMs instructing them which upstream channels to use, describing the parameters of the channel and assigning times for transmission which are simultaneous on multiple channels for upstream wideband capable CMs.

摘要： An interleaver for any modem or transmitter which transmits digital data. The interleaver eliminates the iterative divide step of a first prior art method to calculate the final depth of each block and the divide followed by a multiply step of a second prior art method. This is done by calculating the minimum depth, i.e., number of rows, for each 2-D block of data using a divide step and retaining the remainder. The remainder is used to determine how many blocks get an extra row when the burst length and width of each row precludes all blocks from having the same number of rows.
