Embodiment Construction

[0040] at least for Figure 1-8 The discussion presents various embodiments that include one or more novel and inventive aspects or features. At least one of these embodiments provides a system for communicating data over cables using typical features of wireless systems. Specifically, at least one embodiment uses time division multiplexing over coaxial cable. Such a system allows, for example, cable television operators to provide television signals in one part of the spectrum and additional services on another part of the spectrum. The additional services may include, for example, Internet access, including access to search the Internet and view web pages on the Internet, and access to receive services on the Internet such as, for example, video-on-demand.

[0041] at least for Figure 9-20 The discussion of presents additional embodiments, and at least one of these additional embodiments extends the understanding of Figure 1-8 discussion. A particular implementation i...

Abstract

One particular time divisional function (TDF) system uses both contention based and time division based access for acquisition of an uplink channel in order to support data and sporadic user controlling messages over a cable access network. One system uses a hybrid time slot in a TDF superframe of time slots to allow TDF Stations operating in contention base time slot. One particular implementation includes using a frame structure (2600) for communication. The frame structure supports at least two communication modes. The communication modes include a time division mode in which a slot in the frame structure is reserved for a device and a contention-based mode in which a contention slot in the frame structure is used by multiple devices for data communication.

Description

technical field [0001] This disclosure is generally directed to various aspects of communication systems. Background technique [0002] Communication systems exist for connecting users with information. Such systems may use coaxial cables as well as wireless networks. Existing systems exhibit various limitations. Contents of the invention [0003] According to a general aspect, a frame structure is used for communication. The frame structure supports at least two communication modes. The communication modes include: a time-division mode in which time slots in a frame structure are reserved for devices; and a contention-based mode in which data communication is performed by multiple devices using contention time slots in the frame structure. [0004] According to another general aspect, a data-carrying signal is structured according to a format supporting multiple modes of communication. The signal includes a first portion structured into time slots for the time divisi...
