A spreadsheet file user profile maintains location links between the imported source text files and their location within the spreadsheet file.

Abstract: System for deferring the delivery of an e-mail sent by a sender to a receiver through a data transmission network such as Internet wherein a Message Transfer Agent (MTA) associated with the sender is in charge of transmitting over the network any e-mail being sent by the sender. The system comprises a retention server for storing the e-mail whose delivery is to be deferred and an authorization server for giving the retention server the authorization to deliver the stored deferred e-mail to the receiver when predetermined criteria are met. The MTA associated with the sender includes a retention enabling program for sending the deferred e-mail to the retention server when there is an indication in the e-mail that it is to be deferred.

Abstract: A content stream user defines preferences, which are compared to aggregated metadata describing in real time a plurality of content streams to which the user has access. The metadata for each content stream may be generated by automated analysis of onscreen indicators, noise levels in standard video or audio sequences, or speech recognition or image recognition data applied to identify particular keywords, individuals, etc. Where a match between content and user preferences is identified, the user is notified, and may be given the option of switching to the matching content stream. A number of approaches are used to ensure that the user is able to access the whole of the content of interest, and does not miss the starting porting.

Abstract: A method of delivering a regional television channel to a user over an Internet Protocol Television (IPTV) service comprising the steps of forming a multicast of channels intended for delivery to a user each channel having a specific channel slot, the multicast of channels including one or more regional channels corresponding to one of the multicast of channels; broadcasting the multicast channels to the user through a regional gateway; forming a regional channel control signal for scheduling and requesting broadcast of the at least one regional channel instead of the one of the multicast of channels; transmitting the regional channel control signal to the regional gateway; and in accordance with the regional channel control signal, at the required time, switching the regional gateway to the at least one regional channel instead of the corresponding one of the multicast channels such that the regional channel is in the specific channel slot of the corresponding channel.

Abstract: A method of transmitting a web object over a broadcast standard channel to a remote mobile device, the method comprising the steps of accessing one or more web objects from a web server, wherein each web object has an address, determining a hierarchy and an address linkage pattern for the one or more web objects, identifying a closed web site from the one or more web objects, translating the address of one of the web objects in the closed web site to an indicator which is based on the hierarchy and address linkage pattern of the web objects; storing the closed web site such that the web object is stored with its associated indicator, and transmitting a required web object from the stored closed web site at a frequency and a repetition rate which is determined from the indicator.

Abstract: A method of controlling the storage of web objects in a storage media, the web objects forming a closed web site and being adapted for delivery to a user, the web objects being stored on the basis of predictive determinations of which web object has the highest probability of being selected from the closed web site by the user.

Abstract: A method for managing bandwidth for transmitting the content of a video to users requesting the content. The total time duration T of the video is divided into N consecutive sessions. A unicast or multicast connection in normal play mode may be created for each session only at discrete times separated by a time increment ?T equal to T/N. An overall bandwidth B is established for transmitting the content of the video to the users. The overall bandwidth B is divided into a first part B1 and a second part B2. The first part B1 is allocated to a normal play mode of the video during the N sessions such that B1=N*R, where R is the bit transmission rate of the video. The second part B2 is allocated to unicast sessions dedicated to implementation of at least one non-normal streaming mode of the video.

Abstract: A method of providing a preview and or replay function for a content on demand service provided by a service provider to a plurality of users. A method in accordance with an embodiment of the invention includes: generating a first stream of content for transmission to a user; generating one or more other streams of content, each of which are derived from the first stream of content and differ therefrom in that the other streams are each in advance of or after the first stream by a time difference; transmitting the first stream of content to the user; receiving a request from the user to view a preview or replay of a part of the content; and switching the user to one of the other streams of content, which other stream is at the time difference that matches the requested preview or replay part of the content.

Abstract: A method and computer system for managing bandwidth in a content on demand service provided by a service provider to users. A request is received from a user to receive the content. If it is ascertained that a total number of users requesting the content within a predetermined time period is below a first specified threshold, then the user is connected to a unicast stream of the content. If it is ascertained that a total number of users requesting the content within a predetermined time period is not below a first specified threshold, then the user is connected to a first multicast stream of the content. A video carousel includes at least two multicast streams that contains the first multicast stream. Each multicast stream has been or will be initiated at a unique time slot of a time period that is equal to the time duration of the content.
