It includes 10-bit video ADCs and supports both NTSC and PAL. The TVP5146 may be equivalent to LSI Logic's L2146: http://focus.ti.com/lit/ds/symlink/tvp5146.pdf The TVP5146 device is a high quality, single-chip digital video decoder that digitizes and decodes all popular baseband analog video formats into digital component video. The TVP5146 decoder supports the analog-to-digital (A/D) conversion of component RGB and YPbPr signals, as well as the A/D conversion and decoding of NTSC, PAL, and SECAM composite and S-video into component YCbCr. This decoder includes four 10-bit 30-MSPS A/D converters (ADCs).

It integrates a second dedicated ATAPI port, an NTSC/PAL TV encoder, video DACs and a USB controller. It offers key features, such as MPEG-4 video playback; concurrent operation of timeshifting (pause, rewind and fast-forward of live television) while archiving programs from hard disk to DVD. Tuner, TN brand, +5V, TNJ-8865-CFR1 http://www.tenas.net/Product/en/product_list.asp Looks like a multi-format "MK4 Mini-TUNER", PAL D,K,I,B,G and SECAM.
