Orb Networks has introduced a free service, called MyCasting, that lets anyone with a mobile device equipped with a browser and media player access Internet-based streaming video.

Video served up by sites such as YouTube, Google, Guba and DailyMotion are typically not formatted to play on mobile devices. Orb’s software automatically transcodes video streams into the appropriate media format, bitrate, and screen resolution for mobile phones.

Users have to download the free Orb software to their Internet-connected PCs, and set up an account with Orb. They can then stream video to their mobile phones, PDAs or laptops.

For those who want to enjoy their Internet videos on a mobile device, Orb has developed the “OrbThis” browser plug-in that allows users to add the URL for their favorite Internet video clips to their MyCast library directly from their browser.

When users find content, they press the “OrbThis” button and the video clip is immediately available through their Orb account.
