Los Angeles-based RealD, a developer of 3D projection technology for movies, said yesterday along with Sonic Solutions that the two are in a strategic alliance. The firms said that Sonic will integrate RealD's 3D format into its RoxioNow entertainment platform, in order to support 3D entertainment in consumer electronics devices. Financial details of the alliance were not disclosed. The firms said that the new 3D-enabled products from Roxio are expected sometime this summer. RealD's format enables transmission of multiplexed 3D content using HD.
