The maximum ATSC bandwidth is 19.39 Mb/s. It is conceivable that 1080 high definition 3D content could be fit into this.

Hi Alfred
Thanks for you reply but could you give me some actual figures as well?
Regards, Niklas

One of the most promising techniques for encoding the image data with depth is to take one image (let’s say the left eye) and then only transmit those pixels that are different for the right eye. Since most of a scene is common to both eyes, the resulting data set is much smaller than the two full resolution images on their own. Add in H.264 (MPEG4) compression, which is about twice as efficient as the MPEG2 used by ATSC for broadcast television, and you should be able to fit a full high definition 3D data stream on a standard television broadcast channel’s bandwidth. A telco with fiber optic would have no problem handling the data stream.

How much bandwidth would you need as a Telco to stream a HDTV 3D stream compared to a normal HDTV stream? Does anyone know?
