It is called "half HD" because 960 is 1920/2. It is a way to have "HD"
content in the number of lines with 50% less pixels, so less
decoding/encoding CPU power. And it is easy to scale to the full
1920x1088 resolution, and with an analog TV output, there is no
differences (There is no column on analog TV signal, only lines).

You can check, the pixel aspect ratio of this stream in 2:1, so the
display size is really 1920x1088.

Best Regards.
