Standard Definition (Sd) And High Definition (Hd) - Sony BRAVIA Troubleshooting Manual

Display/Picture

Standard Definition (SD) and High Definition (HD)

Standard Definition (SD) has a vertical resolution between 480 and 576 lines.
High Definition (SD) has a vertical resolution between 720 and 1080 lines (Full HD).
When SD video signal is displayed on HD TV, the image will either appear smaller on
or up-scaled (resized) to fit the screen.

Some DTH or set-top box (depends on the providers) may upscale SD signal to HD
levels. However, this can erode the quality of the pictures or even crop the image. For
example, 4:3 image can be up-scaled and then cropped to display full screen image on
16:9.
Tips:
HD TV channels require you to have a
special set-top box that receives HD signals
and routes the content to the TV via an
HDMI cable.
