Thema: Treiberfrage..

Guten Morgen

Diesen Treiber habe ich beim Winddk von Microsoft gefunden und habe jetzt eine Fraage dazu. Er heißt testcap.

Da steht ja

Zitat:

The driver simulates the front-end components of a PC/TV, including input selection, TvTuning, TvAudio control, and digital video streaming

Heißt das jetzt das ich mit diesem Treiber einen ganzen Fernseher simulieren kann bzw. das der Treiber mir am Rechner alle Fernsehfunktionen beretstellt wie ein echter Fernseher?

Sodass ich dann alle TV Funktionen z.b. mitdem Windows Mediacenter unter Windows7 nutzen kann?

Ich bitte um erklärung.. Denn obwoh ich im Englischen gut bin und den Sinn des Treibers so interpretiert habe möchte ich sicherheitshalber befor ich den Treiber bei mir ausprobiere hier nochals nachfragen. Vllt habe ich den Sinn des Treibers ja auch falsch interpretiert..

Danke für eure Antwort.





Testcap is a sample WDM Stream class video capture driver that does not require any hardware for operation. The driver simulates the front-end components of a PC/TV, including input selection, TvTuning, TvAudio control, and digital video streaming. You can use TestCap as a prototype for developing your own kernel streaming minidriver.
The TvTuner component supports tuning modes of Analog TV (NTSC/PAL/SECAM), AM/FM Radio, and ATSC (American Broadcast Digital Television).
Testcap appears in a DirectShow graph as four separate filters:

• Testcap Capture
• Testcap TvTuner
• Testcap TVAudio
• Testcap Crossbar

The capture filter produces five output streams, two of which are Capture and Preview, which produce a variety of colorbars and grayscale patterns depending on the video input selected on the crossbar. The capture and preview streams contain video samples in either RGB24 or YUV422 color spaces and offer a large number of different image dimensions. The other three capture streams are VBI (vertical blanking interval), HWCC (hardware closed captioning), and HWNABTS (hardware North American Basic Teletext Specification). These three are VBI streams, and offer simulated CC and NABTS waveforms for decoding, and simulated hardware-decoded CC and NABTS.
TestCap contains sample implementations for almost all of the kernel streaming property sets involved in WDM video capture. Most of the property set implementations are useful only as prototypes, which you can borrow for your own implementations because Testcap doesn't control actual hardware.
TestCap represents one extreme of combining all functionality representing the front end of a PC/TV into a single driver. The other extreme is to create a separate driver for each element: TvTuner, TvAudio, Crossbar, and Capture.
USING THE SAMPLE
The TestCap sample is completely contained in one directory. Build the sample with the standard DDK build utility. You may build the sample in either a checked or free DDK build environment. TestCap compiles for Windows 98 and later, and Windows 2000 and later operating systems. The sample also compiles for 64-bit Windows platforms. The resulting binary from the build process is Testcap.sys, which is compatible on x86 and Alpha platforms.
Testcap is not a PnP driver, and because no hardware is involved you must manually install it:

• Right-click My Computer and select Properties. Select the Hardware tab. Then select the Hardware Wizard and then Add new hardware.
• Click next when you see "To install hardware which is not Plug and Play compatible, click Next."
• Select "No, I want to select the hardware from a list."
• When you see "What type of hardware do you want to install", select Sound, Video, and Game Controllers.
• Select "Have Disk..."
• Browse to "Testcap.inf".
• Browse to "Testcap.sys" when requested.

TestCap has been tested with the following applicatons: Graphedt.exe, AMCap.exe, and WebTV for Windows.
The Windows Hardware and Driver Central website contains general information on driver and hardware development.
The Microsoft DirectX website contains information on DirectShow.

Allerdings musst du vorher noch eine Hellseher-Kristallkugel in den Computer einbauen, um ohne Verbindung zu wissen wo welches TV Signal herkommt. Ah und GEZ *fingerzeig* !

Bevor die naechsten 27 aehnlichen Topics hier kommen, wie in dem Englischen Forum: Man kann mit Software Hardware emulieren, bis zu einem gewissen Grad zumindest (siehe z.B. Consolen-Emulatoren) allerdings keinen Content/Inhalt/Daten, wie auch. Das Zitat hier (und der Link in deinem anderen Forumla topic) ist fuer Software-Entwickler gedacht. Die meisten Fragen die du bestimmt sonst noch so hast lassen sich bestimmt besser mit "common sense" beantworten, als mit irgendwelchen komplizierten Virtualisierungs-Softwares und MSDN Artikeln.
