Patent CA-2208175-A1 (CA)
Inventor: TOW AGNES C
IPC: H04M3/533
Filed: 1997-06-18
Abstract: A mailbox messaging system stores a message from a caller to a mailbox owner and modifies on demand a mailbox owner's mailbox structure on at least one storage device. When messages are deleted from the mailbox, the disk space allocated for the mailbox on one or more storage devices is reduced or deallocated. Conversely, when messages are added to the mailbox, the disk space allocated for the mailbox on the storage devices is increased to meet demand. The messages associated with a given mailbox may be located on any number of storage devices and need not be stored consecutively on the same storage device area or on the same storage device. The storage devices can be located at different locations over the communication network.

Title: Compressed digital-data interactive program system
Inventor: FREEMAN MICHAEL J
IPC: H04N5/44
Filed: 1996-05-17
Abstract: An interactive cable television system is disclosed which utilizes a standard cable television distribution network for simultaneously providing a plurality of viewers with an interactive television program comprising a plurality of signals related in time and content. Video signals (1) are transmitted in a digital format, more than one signal being multiplexed onto a data stream on a single channel. The video signals (1) may be compressed for efficiency. A receiver (7), in conjunction with a signal selector (8), selects a particular NTSC channel for playback, then selects a particular video signal from the data stream, and decompresses the video signal for playback. Seamless switching between video signals on different channels is provided. An alternative embodiment is disclosed wherein the various signals which comprise the interactive program are switched at the head end (300) rather than at the receiver (7). The multiple choice control unit (9) selects a desired signal by relaying the multiple choice selections of the user through a relay box (17) back to a remotely located switching station. The switching station routes the correct video signal down the appropriate cable channel for the particular user.

Title: A system and method for managing packet-switched connections
Inventor: MACCALLUM LOUISE A
IPC: H04L12/56
Filed: 1997-11-12
Abstract: A system and method for managing connections between one or more local terminals and one or more remote systems over a packet-switched network is disclosed.  The invention includes a gateway computer that forms a bridge between the local terminals and the one or more host systems, the gateway and the local terminals including computer software instructions for embedding and filtering special connection identification information in each transaction request. The local terminals embed connection identification information into each request packet requesting a connection to a remote host system, and the gateway filters this information and verifies that the gateway and local terminal(s) are synchronized. The gateway then manages the communication to the host system using the native protocol of the host, thereby minimize communication over the packet-switched network. By synchronizing the connection attempts of the local terminals to the gateway, problems associated with connecting multiple transaction-generating terminals to one or more host systems via a packet-switched network are minimized.
