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.

An information appliance receives streaming information. The information appliance includes a storage buffer and a writer module which receives the streaming information and writes the streaming information to the buffer. A plurality of reader modules are configurable to read the streaming information from the buffer independently of one another.

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, e.g., using a priority-based policy. 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, which may be ranked, for each activity. This allows the resource consumers to be dynamically changed from one configuration to another as operating conditions change.

One aspect of the present invention leads to a method of handling streaming information. The method includes receiving the streaming information and analyzing the streaming information to locate one or more points of interest in the streaming information. An index of the one or more points of interest are generated. The index is delivered to a user separate from the streaming information. Rendering of the streaming information is controlled based on the points of interest.

Method and system for handling streaming information

A streaming information handling system receives streaming information and analyzes the streaming information to locate one or more sync points in the streaming information. The streaming information and sync point location information, indicative of a location of the sync points, is provided to a storage module. The streaming information and at least a portion of the sync point location information are stored on the storage module.

Analyzing, indexing and seeking of streaming information

One aspect of the present invention relates to an information appliance for handling streaming information for storage in a circular buffer having a plurality of partitions defined by boundaries. The information appliance includes receiving streaming information from a source of streaming information and forming data blocks wherein each data block includes a payload field capable of holding a portion of the streaming information and an identification field indicative of the source of the streaming information. At least one data block is written to the circular buffer to partially fill a partition and at least one padding block is generated having a field indicative of non-streaming information and having a size being a function of remaining space in the partition. The padding block is written to the circular buffer adjacent a boundary of the partition.

System for storing streaming information in a circular buffer by using padding block containing non-streaming information to fill a partition of the buffer

A method is provided for handling streaming information encoded with a data structure having a data block format. The data block format includes a data block having a header portion and an end portion. The header portion includes a prefix field having a pointer to a succeeding data block and the end portion includes a suffix field having a pointer to a preceding data block. A first data block size field is included in the header portion and indicates the size of the data block and a second data block size field is included in the end portion and indicates the size of the data block. A payload field is bounded by the first data block size field and a second data block size field. The payload field includes streaming information to be rendered.

Data format for a streaming information appliance

An information appliance receives streaming information and includes a buffer, a writer module, a reader module and a synchronizer. The buffer has a plurality of storage locations, a logical head, a logical tail and a valid data area between the logical head and the logical tail. The logical head and the logical tail move sequentially through the plurality of storage locations in a first logical direction. The writer module has a write position at the logical head of the buffer. The writer module receives the streaming information and writes the streaming information to the buffer at the write position. The reader module is coupled to the buffer and has a first read position which is temporally movable with respect to the write position. The synchronizer is coupled to the writer module and the reader module and maintains the first read position within the valid data area.

A data block format for streaming information includes a first data block size field and a second data block size field, each of the fields indicating the size of the data block. A payload field is bounded by the first data block sized field and the second data size in the data block format.

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.

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 &ldquo;activity&rdquo; at the resource manager and builds one or more &ldquo;configurations&rdquo; 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.
