Chrontel's New TV Encoder Chip for Mobile Devices
"Targeted at handheld systems, a TV encoder chip dubbed the CH7023 enables mobile telephone handsets, PDAs and portable media players output video directly to a conventional NTSC or PAL television. The CH7023 video interface chip from Chrontel Inc. accepts digital input resolutions from 220 X 176 pixels up to 720 X 576 pixels, and 8, 12, 15, 16, 18 or 24-bit digital RGB or YCrCb data input. With two 10-bit high-speed DACs, the CH7023 can drive either CVBS or S-Video analog outputs. The device incorporates Macrovision copy protection, up/down pixel-by-pixel display scaling, programmable power management and adjustable brightness, contrast, hue and saturation control. The CH7023 can accommodate most input display LCD data rates, supporting pixel clock frequencies from 2- to 64-MHz. The device consumes 70-mA, and supports low-power and long battery life with I/O voltages of 1.2 to 3.3-V."
About time. With PDA TV-out solutions on the decline, the CH7023 has the potential to work wonders if used in upcoming mobile devices. Of course, the key word there is "if". I guess we'll find out soon enough as the NTSC/PAL-compatible chip should be available to manufacturers in Q2 2006 at an oh-so-wonderful bulk buy price of $3 each.

Not just handheld either... Since I've now taken delivery of my nice and shiny (not for long, I'll bet) iPod Video... what money would you like to place on iPod Video v2 having video encoding as well as decoding?
