The SAA7134 TV Card chipset from Trident Microsystems supports viewing of both digital and analog television broadcast on PCs. The chip is capable of digitizing and decoding video and audio, while also capturing data-streams through the PCI bus. The device supports all features of PCI Specification 2.2, including the Advanced Configuration and Power Interface (ACPI). The video feed is digitized by two 9-bit ADCs operating at 27 MHz, while video sampling is done according to ITU-R BT.601 standards, with 720 pixels for each line. The device is capable of providing outputs in both RGB and YUV analog video formats, as well as ITU and VIP digital video formats. It also supports the TV decoder standards of NTSC, PAL and SECAM.

The chipset offers out of the box support for adaptive anti-aliasing (AAA), which is a technology used for removing jagged and blurred edges of transparent 3D textures from video feeds, especially in games and TV programs. The anti-aliasing of opaque textures can be carried out by using Multisampling techniques, which cleans up jagged edges of overlapping polygons on the screen. However, in case of transparent textures, this technique is likely to fail, as those are not displayed directly on screen, but stay on the background and have to be handled within a separate layer. That is where adaptive anti-aliasing comes into play.
