[QUOTE="bionicdonkey, post: 3289, member: 10370"] I thought i might share what little i've on a DTV Plugin. I've taken a different approach than i'd normally do and document what needs to be done rather than just try to code it. So far i've documented 3 functions: [code] /// <summary> /// This function is ued to setup the initial part of the graph. /// A tune request must the sent before the Network Provider is connected to the other filters. /// Just create a tune request, filling the frequency and bandwidth/symbol rate with -1. /// </summary> /// <returns>true if it's setup, false if it's not</returns> public bool setupGraph() { // BDA Network Provider // Initialise Tuning Space (using the setupTuningSpace function) // Create NP based on a network type // Add NP to graph // Submit Tune Request // Tuner Device // Create Tuner device from device selected in setup // Add Tuner Device to the graph // Start the graph to make sure the device is available // Connect Network Provider to Tuner Device // Capture Device // Create Capture Device by matching it with the Tuner Device // Add the Capture Device to the graph // Connect the Tuner Device to the Capture Device // Mpeg2 Demultiplexer // Use CLSID_MPEG2Demultiplexer to create the demux // Add the Demux to the graph // Connect the Capture Device to the demux (which will setup the pins) // Transport Information Filter // Enumerate the KSCATEGORY_BDA_TRANSPORT_INFORMATION category // Add the filter to the graph // Try to connect to Pin 1 on the Demux // Sections & Tables Filter // Enumerate the KSCATEGORY_BDA_TRANSPORT_INFORMATION category // Add the filter to the graph // Try to connect to Pin 5 on the Demux return false; // Change to true when function complete } /// <summary> /// This is the function for setting up a local tuning space. /// Funtion is based on code written by Nate from DigitalWatch. /// It may be changed to use the Windows Registry.
