Abstract: The present invention provides for the collection and delivery of broadcast data. Broadcast data is captured by broadcast data sources from television broadcasts and the captured broadcast data is collected by a broadcast data source miniport. The miniport differentiates the broadcast data to separate the requested broadcast data and to separate the broadcast data that complies with a protocol from broadcast data that does not comply with a protocol. The nonrequested broadcast data is preferably discarded and the broadcast data that does not comply with a protocol is encapsulated with appropriate headers. The broadcast data is then transferred through the network or system to a common application interface such as Winsock through NDIS and a protocol such as UDP/IP. Alternatively, a RawData module is used that does not rely on sockets and is capable of communicating with the miniport.

Abstract: EPG services are provided, which enables a device such as a computer, a set top box or the like to collect EPG data from multiple EPG data providers or sources. The EPG data is collected at the device by EPG loaders. Each EPG loader collects EPG data from a particular source. The EPG loaders deliver the EPG data to a writer module, which performs scaling and formatting functions to the EPG data. The writer module also stores the scaled and formatted EPG data in a database or other storage. Once stored, applications gain access to the EPG data through a control module. The writer module may also be implemented by chaining EPG loaders in a priority scheme. However, EPG loader interaction reduces independence and forces more rigid interface and implementation constraints upon the design of EPG loaders. The control module provides the accessed EPG data to the applications. EPG services function to isolate the operation of the applications from the EPG data sources.
