    摘要： There is provided a system for providing content through a Content Delivery/distribution Network (CDN) that includes a plurality of storage entities. A Content Requesting device (CR) generates and transmits requests for content. A Content Server (CS) receives the requests from the CR, provides notifications regarding a current location of the content, and at least one of stores the content and interfaces with the CDN to distribute the content to one of the plurality of storage entities. A Content Consuming device (CC) receives the notifications from the CS and retrieves the requested content from one of the CS and the one of the plurality of storage entities based on the current location of the content specified in the notifications.

    摘要： A method for downloading and displaying a video program using a mobile terminal that includes a first radio access network having a first data transfer rate and a second radio access network having a second data transfer rate faster than the first data transfer rate. The downloaded video program is displayed at a predetermined playback rate. Excess portions of the downloaded video program that result when a rate at which the video program is downloaded exceeds the predetermined playback rate are buffered. A third data transfer rate that is lower than the first transfer rate is calculated in response to the predetermined playback rate, the buffered excess portions and the time duration of the remainder of the video program. The third data transfer rate is negotiated with the first network for downloading the video program when the difference between the first and third data transfer rates exceeds a threshold level.

    摘要： The method for providing micro-billing for internet services includes establishing a micro-billing agent (MBA) within a user's access point (i.e., Internet Service Provider—ISP). The MBA contains the user's billing information and keeps that information exclusive to the MBA. By retaining the user's information with their access point, the user can conduct more secure online transactions, particularly for low cost transactions, without the inconvenience of inputting or transferring personal purchasing information to the online store. According to one aspect, the purchase page may be previously encoded with a micro-billing option which would enable the MBA to obtain user authorizations in online transactions in a more streamlined and secure manner.

    摘要： A method for descrambling secure content received over a network is disclosed. The method is operable at a receiving device (150) located at a remote site in communication with a network (140) for receiving a first information item scrambled using an encrypting key (Pu) known by the remote site, descrambling the first information item using a corresponding decrypting key, wherein the information item includes an access code (CAC) and a content key (Kc), receiving a second information item, scrambled using the content key after a server, (120) hosting the second information verifies the access code (CAC) and descrambling the second information item using the content key (Kc).
