With all these companies honing in on bringing HD capabilities to handsets, we were beginning to wonder when someone would step up and lend a hand on the audio front. Thankfully, both Dolby and SRS Labs have come forward at Mobile World Congress to announce separate enhancements to mobile audio, so we'll touch on the former first. Dolby Mobile, hailed as an "audio processing technology platform that brings rich, vibrant surround sound to music, movies, and television programs on mobile phones and portable media players," is available as we speak on the FOMA SH905i and FOMA SH905iTV in Japan, but will hopefully float out to other handsets in due time. As for SRS Labs, it's boasting its own SRS CS Headphone technology, which reportedly "takes stereo or surround encoded 2-channel audio and processes it using an ultra-low-power Circle Surround decoder to create 5.1 highly accurate channels." Granted, we're still wondering exactly how 5.1 channels make their way though stereo earbuds, but we'd be up for a listen, regardless.

On the same day that Texas Instruments chose to showcase a new chip that would enable HD recording capabilities on cellphones, On2 Technologies is taking a moment from its hectic day in Barcelona to trumpet an all new 1080p hardware RTL video decoder. The Hantro 8190 reportedly supports Adobe Flash along with H.263, H.264, MPEG-2, MPEG-4, VC-1, Sorenson Spark and VP6 video formats, and it can even handle JPEG images up to 16-megapixels. According to On2, the device was created to be easily integrated with ARM, MIPS and "other embedded CPU and DSP cores," and can supposedly decode 1080p H.264 video at 30 frames-per-second using a clock frequency of just 165MHz. As it stands, the Hantro 8190 is currently available for licensing, but only time will tell who's going to bite.

It's no secret that Texas Instruments has been pushing to get its technologies into more cellphones for awhile now, and considering that even Nokia reckons that HD recording capabilities in mobiles is but a few years away, it's not too shocking to hear what TI busted out at Mobile World Congress. Reportedly, the firm has unveiled "a chip to support cellphones with mini projectors and another chip that would let users record high-definition video on their phones." After showing prototypes in the past, TI asserted that it had chips "ready for production" for pico projectors that could be integrated into a variety of handsets, while the OMAP3440 -- which would let consumers capture HD footage on the same device that gives those thumbs a workout -- will be available in Q2 for handset makers to test out.
