US Patent:

6397382, May 28, 2002

Filed:

May 12, 1999

Appl. No.:

09/310441

Inventors:

Peter S. Dawson - Canton MA

Assignee:

Wind River Systems, Inc. - Alameda CA

International Classification:

G06F 944

US Classification:

717130, 717158, 711138, 711139

Abstract:

A method and system of monitoring code as it is executed by a target processor is provided for debugging, etc. Standardized software code function preamble and postamble instructions are dynamically replaced with instructions that will generate a predetermined exception. The exception generates a branch to a conventional exception vector table. An exception routine is inserted into the vector table, and includes instruction(s) to disable the data and/or address caches. Subsequent instructions in the vector table execute the replaced preamble instruction and, with or without re-enabling the cache, branch back to the address of the program code immediately following the faulted preamble address. Instructions of the function executed while cache is disabled are executed on the bus where they are visible, as opposed to within cache.

International Classification:

H04L 12/28
H04L 12/56

US Classification:

370389, 370394

Abstract:

Streaming media network streams are modified using a sequence field with the IP layer 3 protocol compatible with already deployed IP switching systems except as noted for device and system testing and operational monitoring which can be used to detect the loss or out of order delivery of packets belonging to a stream. This approach can also provide the ability to numerically characterize the loss in terms of total loss, loss burst size, and loss frequency. By utilizing the bit locations of the IP-defined datagram Identification (ID) field and a unique numerical sequence, loss and out of order delivery may be tracked while avoiding the overhead and complexity associated with added upper layer protocols while gaining other key advantages such as in-situ marking of stream attributes.

International Classification:

H04L 1/00

US Classification:

370252, 714 46, 714 48, 709224

Abstract:

Streaming media network transportation streams are created using an electronic system and transmitted via an electronic interface such as an existing system network conduit (i. e. Ethernet, USB, or other packet-based architectures). A scalable hardware and/or software compute engine modifies an initial stream's identifier(s) while replicating the stream content to economically create streams. Hence, an entire network's capacity of active streams may be created from a single initial stream. In one examples, an initial stream is stored in advance of transmission for such use. In other examples, an initial stream is received and processed to dynamically create streams from the initial stream as the initial stream is being received.

International Classification:

G06F 15/173

US Classification:

709224000

Abstract:

Streaming media network parameters are measured using an electronic system and displayed directly to a user or transmitted via an electronic interface such as an existing system network conduit, either in or out-of-band. A scalable hardware and/or software compute engine filters and reduces network parameters to simplify tracking the instantaneous and long term streaming media performance of the network. Hence, the entire set of active media streams is continuously monitored concurrently, thereby providing the ability to detect impairments as well as predict impending impairments. In one example, an existing packetized network conduit containing streaming media is tapped to concurrently and objectively analyze the streaming media streams, producing statistics (such as delay factor and media loss rate) and alarm-type events according to predetermined rules. Tapping the existing packetized network in multiple points provides comparison points and assists in pinpointing the source(s) of the impairment(s).

International Classification:

H04N 7/173

US Classification:

725109

Abstract:

Aggregated information is accessed on a computing device. The aggregated information includes video content information associated with video content and related end destination information. The aggregated information is further processed to render at least a portion of the aggregated information on a publically-accessible information medium. Thus, published content is generated.
