PCIe interface chipsets

In relation to V4L-DVB devices, a PCIe interface chipset is a bridge between the device's receiver (in the case of TV tuner devices) and A/V inputs (in the case of some devices) and the host computer's PCIe "bus" (which really isn't a traditional bus, but rather a point to point serial connect lane(s)). Some examples of PCIe interface chipsets that are used in V4L-DVB PCIe cards include:

• ATI Theater 550
• ATI Theater 650
• ATI Theater 750
• Micronas APB 7202A nGene dual-channel PCI-Express multimedia controller ... see NGene devices for development info
• Philips/NXP SAA7162 (dual A/V decoder) and SAA7160/SAA7161 (multimedia A/V bridge) ... see Saa7162 devices for more info
• NXP SAA7164

Currently, only the CX23885 and SAA7162 IC families have published drivers from LinuxTV.
