Abstract
Description
technical field
[0001] The invention relates to mobile multimedia broadcasting technology, in particular to a device, method and terminal for simultaneously displaying multiple sets of programs. Background technique
[0002] The advent of television has added a kind of communication medium with rich pictures, text and sound for people to transmit information, and the rapid and effective transmission of information has accelerated the progress of television related technologies. Analog TV has experienced black and white TV, color TV, color TV with remote control, and according to the improvement of imaging principle, LCD TV, plasma TV, rear projection TV and so on have appeared. And the window has also evolved from the original single window to two windows (ie picture-in-picture) or multiple windows displayed side by side. Dual-window picture-in-picture in analog TV requires two tuners to receive program signals at different frequency points, and then perform low-noise ampli...
