    摘要： In a multi-format transport stream decoder that performs a desired process on first transport streams of different formats to generate a second transport stream, a process request information input unit (APR) is supplied with process target packet data (Pi) and process request information (ScW) indicative of process details. A stream identification information providing unit (TSRi) provides stream identification information (TSID). A packet data retaining and identifying unit (DBA) retains each pieces of first packet data (Pi), and compares the stream identification information (TSIDe) and packet data identification information (PIDe) of the first packet data (Pi) with the process request information (ScW) to determine whether the information is to be processed.

    摘要： Resource management architectures implemented in computer systems to manage resources are described. In one embodiment, a general architecture includes a resource manager and multiple resource providers that support one or more resource consumers such as a system component or application. Each provider is associated with a resource and acts as the manager for the resource when interfacing with the resource manager. The resource manager arbitrates access to the resources provided by the resource providers on behalf of the consumers. A policy manager sets various policies that are used by the resource manager to allocate resources. One policy is a priority-based policy that distinguishes among which applications and/or users have priority over others to use the resources. A resource consumer creates an 'activity' at the resource manager and builds one or more 'configurations' that describe various sets of preferred resources required to perform the activity. Each resource consumer can specify one or more configurations for each activity. If multiple configurations are specified, the resource consumer can rank them according to preference. This allows the resource consumers to be dynamically changed from one configuration to another as operating conditions change.

    摘要： A system and method implemented in an interactive television system for restricting or controlling the access rights of interactive television applications and carousels. The system broadcasts modules from a broadcast station to a plurality of receiving stations, which execute applications containing the modules. In one embodiment, the applications utilize a credential consisting of a producer identification number (ID) (61) and an application ID (62) for each of the grantor and grantee applications, an expiration date, a set of permission data, a producer certificate and a signature. An application requesting access and a carousel granting access may be identified by respective producer and applications IDs. The credential utilizes public key encryption to ensure the integrity of the credential. The producer and application IDs may be replaced with wildcards so that rights may be granted to a group of producers or applications.

    摘要： A resource allocation system and method for allocating control of a multimedia resource between at least two computer programs residing on a multimedia client. A tune request data structure receives and stores requests for multimedia resources from the computer programs. A priority weighting schedule is associated with the tune request data structure for defining weighting factor to apply to pertinent characteristics of the request. A find dominant request module determines a priority level to be assigned to each of the stored requests based on the priority weighting schedule. The dominant request is permitted to control the arbitrated multimedia resource.
