摘要： A method and a system for providing a connection using a stream identifier (“id”) are disclosed. In one embodiment, the system identifies a talker node, which provides an isochronous data stream via a communication media. Once the talker node is identified, an identifier and an sub-identifier of the talker node are identified. After identifying the identifier and sub-identifier, the stream id associated with the isochronous data stream is identified in response to the identifier and sub-identifier. Next, the system establishes at least one connection according to the stream id. When the connection between the second and talker nodes is established, the listener node reads the isochronous data stream.

摘要： A method and system for adjusting the bandwidth allocated for isochronous data traffic on an interconnected data bus is disclosed. The present system uses an isochronous resource manager (IRM) to sense a bandwidth change request from a talker. The IRM instigates a bandwidth adjustment associated with the bandwidth change request to one or more bus bridge portals.

摘要： Both small frames and large frames of data are transmitted from a producer device to a consumer device over an IEEE 1394 serial data bus. The small frames of data are preferably transmitted to a small frame buffer associated with a plug at the consumer device. Each transfer of a small frame generates an interrupt at the consumer device when the transfer is complete. For the transfer of large frames of data, the consumer device programs an array of page table entries into the plug control register of the producer device, prior to a transfer of a large frame of data. Each of the page table entries includes a starting address of a memory page at the consumer device to which data can be written. Together, these memory pages specified by the page table entries form a large frame buffer at the consumer device for receiving a large frame of data from the producer device. Preferably, the array of page table entries can be updated by the consumer device, as appropriate, between frame transfers. When transferring a large frame of data, the producer device begins writing to the first page specified in the first page table entry and continues in order, writing to the pages specified in the page table entries, until the entire frame has been transferred. When the entire large frame of data has been transferred, the producer device then updates the plug control register at the consumer device to notify the consumer device that the entire large frame has been transferred.

摘要： Self-describing information is included within a device and contains information relating to a graphical representation of the device, the controls available on the device and the interface required to access those controls. The self-describing information is preferably embedded within a ROM within the device and is read by other devices coupled to the device for presenting a graphical user interface through which the device can be remotely controlled by a user. The self-describing information can also include an address from which additional information about the device and upgrades are automatically obtained. This address is either an internet address or points to a location within a network of devices. The address can also be modifiable. Alternatively, the self-describing information also includes driving software for enhancing the graphical user interface and controlling the operation of the device through another system. This driving software is written either in the native language of the device on which it is uploaded and executed or in a platform neutral language such as Java™. The graphical user interface is presented on a television, computer or other appropriate system for controlling multiple devices through the system. The controlling system obtains the self-describing information from each device within the configuration. The graphical user interface includes a graphical representation of the devices and specific control features available to the user presented in a graphical orientation. Alternatively, a three-dimensional representation of the device is presented with controls represented on the device. If no controlling system is available, a graphical user interface is controlled by an application within the device and presented on an available display.

摘要： An isochronous data pipe provides a bi-directional path for data between an application and a bus structure. The isochronous data pipe includes the ability to send, receive and perform manipulations on any isochronous stream of data, including data on any number of isochronous channels. The isochronous data pipe is a programmable sequencer that operates on the stream of isochronous data as it passes through the isochronous data pipe. The isochronous data pipe is programmed by an application to perform specific operations on the stream of data before the data is either transmitted across the bus structure or sent to the application, thereby pre-processing and manipulating the data before it is delivered to its destination. The operations are performed on both the packet header and the data field of the data packet. The isochronous data pipe can be stopped and started on the occurrence of specific events. In an alternate embodiment of the present invention, the isochronous data pipe is programmed to send and receive both isochronous and asynchronous data, including generating requests and appropriate packet headers.
