Research and Development
One R&D team are now much more concentrating into BD-J authoring and J2ME for mobile games development. The other team are more into cinema where they are trying to develop Digital Cinema shooting and projection. The team now can handle and consult for RED Camera shooting and processing for DI and e-cinema, d-cinema projection. This team is also soon will be ready for stereoscopic 3D cinema handling and projection. The 3D development team is also considering for representing 3D presentation on BLURAY disc. We are currently developing techniques for stereoscopic 3D.
Color Space for BD
The interactive features are presented in 10 bit and 32 bit color space. The Color space for BD is HDTV color space REC 709. But our team is considering about implementing Film color space into BD which means there is no conversion in the color space. As one could see the exact colors of the film on a BD.
Video codec Reports on BD
The R&D team of BluIndia is in a conclusion of using only AVC H.264 Codec for Primary video and observed best audio quality in DTSHDMA compared with uncompressed LPCM in BD. Reasons are given below
H264 is a compression codec is a sustained by mpeg technologies and the encoding process is time consuming compared with VC-1. The support for H264 is for many players whereas VC-1 is supported only by Microsoft. Most of the Hollywood studios support only H264 codec. The team observed a difference in colors encoded from different sources. H264 gives out the best color and motion stretch, quantization and Film grain optimization is best observed with H264 codec.
The team also observed that DTSHDMA audio is preferred to be the best audio quality for BD. Whereas the DTSHDMA takes up less space on the disc compared with LPCM not the space but also the depth of the audio is observed to be good in DTSHDMA. Our team didn’t have the opportunity to test for Dolby TrueHD for Bluray. Very soon we are expecting for the dolby TrueHD encoder and testify its codec versions for BD.
