PICTURE QUALITY :

E-City Digital with Qube Cinema provides a multi-format system and can work with MPEG-2 as well as VC1, H.264 and MPEG-4. While Qube Cinema works on these multiple formats including the MPEG-4 compression format, we strongly use MPEG-2 at 80 Mbits or JPEG2000 at 250 Mbits, as these are the standards specified by Hollywood. These are the only formats that are interchangeable across different manufacturer’s products. With MPEG-2 at 80 Mbits, the image looks better than in conventional film in almost all cases whether the scene is bright or dark. With low bitrate MPEG-4, darker scenes are likely to be of very poor quality in comparison to MPEG-2 picture. There will be considerable blocky artefacts with this compression that can be seen easily on frozen images even by a layperson. Whether the audience directly sees such artefacts or not, they will be negatively affected and perceive the quality to be poor.

 

SOUND QUALITY :

E-City Digital with Qube Cinema uses uncompressed 48 KHz or 96 KHz 24-bit sound tracks and can handle 5.1 and 7.1 surround sounds. When making film vs. digital cinema comparisons with Qube, audiences are immediately struck by the substantial improvement to the clarity of the sound with digital cinema.

 

INTEROPERABILITY :

So far, the film industry worldwide has had one common format for the film print and over the years, any film could be played on any projector anywhere in the world. With the advent of digital sound in the cinema, there was incompatibility and three competing and proprietary formats emerged. Everyone in the film industry is aware of the problems faced by theatres because of this insane sound format war.

When moving to Digital Cinema, it is only natural that the film industry would want a compatible system which would be adopted worldwide instead of a number of incompatible proprietary systems. This was why the Digital Cinema Initiative (DCI) was formed by the Hollywood Studios in order to arrive at an open, common specification and prevent any format wars.

All Digital Cinema server manufacturers embraced this specification and are working to make their products totally DCI compliant. An interim specification was also set in place in which the studios released films until the end of 2007.

This interim format approved by the Hollywood Studios is called MXF Interop and this is the format used by Qube Cinema as well as numerous other manufacturers. The MPEG MXF Interop format uses MPEG-2 picture at a high bitrate of 80 Mbits peak. The files are stored and encrypted exactly as specified by DCI and in a standardized manner – to ensure that they cannot be pirated and also to keep them compatible across different manufacturer’s products. Qube Cinema has been tested for compatibility with content from Dolby, Doremi, GDC etc.
