Title: Transmission and reception of television programs
Inventor: SCHOENMAKERS ARNOLDUS FRANSISC
IPC: H04H20/00
Filed: 1998-04-20
Abstract: A television transmitter transmits addditional information in the form of Web pages along with the television signal. The transmission further includes triggers (71) for selectively invoking said Web pages in synchronism with the program. The triggers include (or refer to) a perceptible signal, e.g. a pictogram or an audible beep. In response to receiving a trigger, a receiver reproduces said perceptible signal without substantially disturbing the television screen. The user is thus timely alerted about additional information related to the television program when viewing it. Then, he may or may not invoke the relevant Web page at his own discretion. To inform the public in advance of the triggers that will be broadcast and to provide easy access to the Web pages at an earlier or later stage, the transmission further includes a table of contents (80) identifying the triggers that are being transmitted during the program. The table of contents itself may be invoked by a trigger (70).

Title: A method for crediting a player of an electronic gaming device
Inventor: ACRES JOHN F
IPC: G06F/
Filed: 1999-04-27
Abstract: A method of providing incentive to play gaming devices connected by a network to a host computer. The casino creates a player account accessible by the host computer. The account can accrue both player-tracking points and account credits. Account credits are applied to a player's account as sign-up incentive, bonus award or other player incentive. When the player inserts his or her card in a card reader at one of the gaming devices, the player has access to the account points and credits. When playing with account credits, the account is debited in the amount of the wager responsive to each game played. The credit meter is simultaneously credited, also in the amount of the wager, thereby effectively providing the player with a free game. In a related implementation, the player can convert account points to account credits thereby redeeming player-tracking points at the machine.

Title: Improved paging scheme for call delivery within a cellular telephone network
Inventor: NGUYEN VIET
IPC: H04W68/00
Filed: 1998-06-30
Abstract: Responsive to receipt at an originating switching node (12(1)) of an incoming call (100), a location request (send routing) message is sent to the home location register for the called mobile station. A routing request (provide roaming) message (104) is then sent from the home location register to the switching node (12(1)) identified by the home location register as currently serving the called mobile station (14(1)). If the mobile station is not authorized to receive service in the areas serviced by the serving switching node a subscribed not found message (214) is returned to the originating switching node. Otherwise, the serving switching node pages (108) for the called mobile station only in those areas it services which are also authorized to provided called mobile station service. Responsive to a paging acknowledgement (110), an appropriate routing number is assigned (112) and transmitted (114) back to the originating switching node. The assigned routing number is then used to establish a trunk connection (116) between the originating switching node and the base station controller for purposes of effectuating call delivery (118).
Patent CA-2296659-A1 (CA)
Title: Push network
Inventor: OKI EIJI
IPC: H04L29/08
Filed: 2000-01-17
Abstract: To transfer push service traffic efficiently, a packet is given a content identifier for identifying the content of the packet, or is given one or both of this content identifier and a category identifier for identifying the category to which the content belongs; and a user registers in advance in the distribution network content identifier related information or one or both of this content identifier related information and category identifier related information, said information relating to content and/or categories that the user wishes to have sent; and the distribution network passes content, or one or both of content and category, wanted by a downstream user. A table for filtering is set by taking into account content identifier related information that has been notified by a user.     To make effective use of memory resources in the table in each node of the distribution network, a content identifier, or one or both of a content identifier and a category identifier, that has been registered in the table but which has become unnecessary, is deleted. Moreover, to ensure that a decrease in throughput at some packet distribution destinations does not affect the throughput of the entire network, means is provided for temporarily storing a packet at a transit node, so that when a packet transfer destination is experiencing decreased throughput, a decrease in throughput at transit nodes upstream of the site of the throughput decrease can be avoided by storing packets in this temporary storage means.
