Patent CA-2516427-A1 (CA)
Title: Cost-effective multi-channel quadrature amplitude modulation
Inventor: MONTA PETER
IPC: H04L27/26
Filed: 2004-03-01
Abstract: A highly-efficient, cost-effective technique for multi-channel QAM modulation is described. The technique employs an inverse fast-Fourier transform (340) as a multi-channel modulator. QAM encoding (304A-304n) expresses QAM symbols as constellation points in the complex plane such that each QAM symbol represents a specific phase and amplitude of a carrier frequency to which it is applied.  In multi-channel systems (300), the carrier frequencies are generally uniformly spaced at a channel-spacing frequency (6MHz, for digital cable systems in the United States). The IFFT accepts a set of complex frequency inputs (308A), each representing the complex frequency specification (i.e., phase and amplitude) of a particular frequency. The inputs are all uniformly spaced, so assuming that the IFFT is sampled at a rate to provide the appropriate frequency spacing between its frequency-domain inputs, the IFFT  will produce a time domain representation of QAM symbols applied to its various inputs modulated onto carriers with the desired channel separation.

Title: Method of synchronization on the uplink channel of a simulcast network
Inventor: ROSIN FREDERIC
IPC: H04W56/00
Filed: 2004-12-14
Abstract: A method of synchronization on the uplink channel of a Simulcast network with a plurality of fixed receivers (BS1-BS4) and a selection unit (20), comprises the following steps. All the receivers are placed in a synchronization search mode (702), in which they search for a synchronization pattern sent by the mobile terminal over the uplink channel. When a receiver detects the synchronization pattern, it produces an initial synchronization context (SC3(0)), which indicates the delay of the radio signal relative to a time reference of the network, and transmits it (705) to the selection unit. The latter broadcasts it (707) to all the receivers that use it to start processing the radio signal. Then, each receiver maintains its synchronization context and transmits it (708-712) to the selection unit on each frame. At regular intervals, the value of an updated synchronization context (SC2(i)) is broadcast (714) to the receivers. Advantage: the synchronization of a receiver which begins to receive the radio signal during a call or alternate turn is facilitated.

Abstract: An ITV application definition language (ADL) used to generate ITV applications for different types of target platforms and devices. The ADL provides a plurality of core data structure types upon which one or more data structures may be built. Data structures storing ITV content presentation and behavior information are referred to as resources.

A resource is also associated with an expiration time stamp that indicates when the resource is to be freed from memory. A resource is of arbitrary length, and contains values that differ from the default values stored at a receiving client device. Resources are also packaged into a module that may be catered to a platform and/or profile of a receiving client. The client may quickly determine whether the module is relevant to it by examining the platform and/or profile ID contained in a header of the module.
