Device, method and terminal for simultaneously displaying multiple programs

Abstract

The invention provides a device, a method and a terminal for simultaneously displaying a plurality of programs, the device comprises a high-frequency module, a demodulation module which establishes a plurality of logic channels, a demux module, a plurality of decoding units, a plurality of display units and a controller, the controller comprises: a relational table establishment unit for establishing the resource allocation relational table as the needed for a user, the resource allocation relational table stores the mapping relations of the logic channels, the decoding units and the display units against each program; a configuration unit for setting the obtained corresponding configuration information to the corresponding logic channels according to the resource allocation relational table; and an allocation unit for allocating the data after the demux to the corresponding decoding units and the display units according to the resource allocation relational table. The simultaneous display of a plurality of programs can be easily and simply realized through the introduction of the concept of the logic channels in the demodulation module and the establishment of the resource allocation relational table by the controller.

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...

AI Technical Summary

Problems solved by technology

Similar to analog TV, at present, most CMMB terminals only have one tuner. If you want to realize the picture-in-picture function, you need multiple tuners, which increases the cost of using this function and is not conducive to the widespread use of this function.
