AI Technical Summary

Problems solved by technology

Previously, in order to determine the specific local interface through which an IP data stream would be received, an application had to execute a complex set of instructions
This added complexity results in unnecessary program overhead, application development costs, and processing delays in establishing connections to broadcast streams

Embodiment Construction

[0019] Various embodiments will be described in detail with reference to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. References herein to the bind() API are intended to refer to any and all implementations of the functionality described herein and illustrated in the Figures, and are not intended to limit the scope of the invention or claims to any particular Function calls, API implementations, software programming languages ​​or applications.

[0020] Currently, a wide range of electronic devices are capable of receiving Internet data via wired and wireless networks, and thus are capable of implementing broadcast and multicast applications. Such devices include personal computers, laptops, and workstations. More recently, cellular phones, personal digital assistants (PDAs) with wireless modems, wireless e-mail receivers (e.g., Blackberry and Treo devices) and multimedia...

Abstract

A method for configuring an IP address to receive broadcast or multicast data flow which modifies the bind() Application Programming Interface (API) to survey available local interfaces to determine their ability to be configured to receive data from a particular IP address, configure a interface to receive the IP address if it is so configurable, bind the IP address to that interface. The modified bind*() API may interact with one or more interfaces to see if each interface is capable of being configured to the IP address. Alternatively, the modified bind*() API determines the configurability of interfaces by consulting the access control list. Policy based routing rules may be implemented so that the modified bind*() operation configures the highest priority interface based upon policy parameters.

Description

[0001] This application claims the benefit of US Provisional Patent Application No. 60 / 836,780, filed August 9, 2006, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to application programming interface tools and methods for establishing IP connections to client processors. Background technique [0003] Internet technology enables the delivery of high-quality audio and video content to locations and devices previously inaccessible by television, radio, and other forms of audio and video distribution. This has led to the development of many new applications and devices for distributing broadcast audio and video streams via the Internet. For example, it is now possible to receive video, eg, television clips, on cellular telephones. This technology has the potential to revolutionize the visual media, television and film industries. Accordingly, there is a growing need for applications that deliver broadcast str...
