4. Stereoscopic image storage and distribution
At the end of the production and post-production stages, the question arises of the formats adopted for storing and distributing stereoscopic images. While it is possible to store two files or two streams of images in full definition, this doubles the storage volume required and the bit rate needed to transport them, compared with 2D images. The aim, in terms of distribution, is to use a single HD channel. Two main families of techniques have been developed to achieve this goal.
-
Frame compatible" technology
The first technique, known as "frame compatible", involves encapsulating the two 3D-s images in a 2D (HD) image format. The advantage of this technique is that it can be used on current networks. However, it requires the operator to continue broadcasting the 2D version of the program on a separate channel, in order...
