Title: Method and apparatus for network content download and recording
Inventor: CALLAHAN JOHN
IPC: H04N7/173
Filed: 2006-03-09
Abstract: Methods and apparatus for providing content to users of a network that can be selectively recorded via the user's equipment. In an exemplary embodiment, the network comprises a hybrid fiber coax (HFC) network, and on-demand (OD) sessions are used to provide high-speed download of the requested content to the users. The user's equipment (e.g., set-top box) is equipped with a high-density recording device which can both record the content onto a selected medium (e.g., DVD) and optionally provide copyright protection via one or more means such as limiting the number of copies that can be made, and/or digital watermarking. The network operator can also restrict the establishment of the on-demand sessions and/or release of the content to subscribers based on parameters including prior purchase of the content by the user, and the timing of the release of the same content via other distribution channels such as rental and retail.

Patent CA-2549100-A1 (CA)
Inventor: WALTON JAY RODNEY
IPC: H04L1/02
Filed: 2004-12-13
Abstract: An access point in a multi-antenna system broadcasts data using spatial spreading to randomize an "effective" channel observed by each user terminal for each block of data symbols broadcast by the access point. At the access point, data is coded, interleaved, and modulated to obtain ND data symbol blocks to be broadcast in NM transmission spans, where ND >=1 and NM >1. The ND data symbol blocks are partitioned into NM data symbol subblocks, one subblock for each transmission span. A steering matrix is selected (e.g., in a deterministic or pseudo-random manner from among a set of L steering matrices) for each subblock. Each data symbol subblock is spatially processed with the steering matrix selected for that subblock to obtain transmit symbols, which are further processed and broadcast via NT transmit antennas and in one transmission span to user terminals within a broadcast coverage area.
