摘要 |
A method for generating a picture-in-picture digital television frame comprises the steps of: converting a first analog television signal into a first digital frame comprising a first prescribed number of pixels; deriving a mean-only frame from the first digital frame, the mean-only frame comprising a second prescribed number of pixels; creating an insertion frame on the basis of the mean-only frame; and inserting the insertion frame into a second digital frame, thereby generating a picture-in-picture digital television frame. A Vector Quantization receiver/decoder comprises a mean-only decode section 20, a full decode section 30, and an image inserter 40. |
