    摘要: A system and method provide random access to a multimedia object over a network. One embodiment of the invention includes a streaming media server that is connected to a client computer over a network. The streaming media server includes at least one multimedia object that is adapted for transmission (“streaming”) across the network. A pre-roll calculation program determines a pre-roll for each segment of the multimedia object and generates a modified multimedia object which includes a pre-roll for each of its segments, a pre-roll identifying a portion of the multimedia object to be transmitted by the streaming media server and received by the client computer prior to playback of the multimedia object at a selected segment. The pre-roll allows the client computer to present, starting at a selected segment, the multimedia object in its entirety without interruption. The pre-roll calculation program further facilitates the design of the multimedia object to minimize delays associated with random accesses to segments of the multimedia object.

    摘要: Techniques are described for providing location-based information and functionality to people and computing devices in various ways. In at least some situations, the techniques include enabling multiple people in a common geographic area to interact in various ways, such as via devices capable of communications (e.g., cellular telephones, computing devices with wired and/or wireless communications capabilities, etc.), while in other situations at least some users who are remote from a particular geographic area may be allowed to inter-communicate with one or more other users or other entities in or related to that geographic area. In addition, the techniques include enabling the creation and maintenance of location-based virtual groups of users (also referred to as “clouds”), such as for users of mobile and/or fixed-location devices. Such clouds may enable various types of interactions between group members, and may be temporary and/or mobile.

    摘要: A number of digital content rendering modules are equipped such that selective subsets of the modules may be employed to render digital content of different media, and of different format types. The modules are organized into a hierarchy, with a selected one occupying a root position of the hierarchy, to exclusively receive the digital contents to be rendered, and that each module is further responsible for verifying the integrity of its immediate downstream modules, to collectively protect the digital contents being rendered. Additionally, in accordance with another aspect, a tamper resistant module is employed to recover digital contents provided in a protected state, obfuscating the recovery. Further, the modules may be of different application domains.

    摘要: A system and a method determine network conditions. The system includes a server computer and a client computer. The server computer is configured to transmit data packets comprising a data object from the server computer to the client computer. The client computer includes a transmission latency detector and a transmission bandwidth detector. The transmission latency detector uses transmission time and receipt time values to determine the changes in time it takes selected portions of the data object to be transmitted from the server computer to the client computer. The transmission bandwidth detector uses identified back-to-back data packets to determine the transmission bandwidth between the server computer and the client computer.
