Interesting PC-TV discussion from NAB. INTC, MSFT, Compaq, Lucent, Intel, Matsushita, and others are mentioned. The All Format Decoder developed by Hitachi and used by Intel could avoid the need for an MPEG-2 decoder "in theory," but you would get a "crude" TV picture in a corner of your PC monitor...........techweb.cmp.com <<In his keynote speech yesterday, Ron Whittier, senior vice president at Intel, announced that the Santa Clara, Calif., microprocessor giant has formally licensed the all-format decoder (AFD) algorithm from Hitachi. By further optimizing the AFD software technology on Pentium, Whittier demonstrated yesterday that it can decode a 720-line progressive-scan (720p) DTV stream and display it at 360p, in full screen at 30 frames per second, on a PC running on a Pentium II at 300 MHz. The AFD holds promise for PC vendors looking for a way to decode all 18 DTV formats specified by the Advanced Television Systems Committee (ATSC) on without adding an extra MPEG-2 decoder IC. It matches with Intel's double goals for DTV decoding on a PC: "Don't add cost" and "Do [it] all in software," according to Whittier. Whittier, however, acknowledged that his company's engineering team has yet to optimize the software-only AFD to achieve a 720p native decode and display. "That's what's next." Whittier also acknowledged that decoding a 1,080i HDTV stream on a PC using the AFD is "in a preliminary engineering phase" and will look "still crude" by the end of this year, when major networks broadcast their first DTV programs. At that point, PCs with the AFD and no extra hardware will likely not be up to the task of decoding programs in full screen. The good news is that the AFD will keep the PC from going dark. If a PC user wants to decode 1,080i in a small window, the AFD could allow that today "in theory," said Mark Richmond, business unit manager for broadcast products at Intel.>>
