Problems solved by technology

[0006] U.S. Patent No. 6,784,945 introduces a method for realizing digital TV multi-picture, which introduces the method of sampling the TV signals of main picture and sub-picture by one or two tuners respectively. Two sets of decoders decode the transport stream after channel demodulation, but no specific measures and methods are proposed for decoding the transport stream of the main picture and the transport stream of the sub picture

Embodiment Construction

[0016] This embodiment includes tuner 1 and tuner 2, selector 1 and selector 2, system decoder 1 and system decoder 2, source decoder 1 and source decoder 2, size converter 1 and size converter 2. The aliaser, the MCU and the buffer, wherein the tuner converts the radio frequency (RF) signal into a transport stream; after the transport stream is selected as a signal source by the selector, the program signal source is transmitted to the system decoder; the system decoder The transport stream is demultiplexed, descrambled, etc., and the output stream is sent to the source decoder; the source decoder decompresses the audio and video compressed signals and transmits the processed image data signals to the size converter, It includes a size converter 1 for adjusting the image size of the main screen and a size converter 2 for adjusting the image size of the sub-screen, respectively controlling the size of the display windows of the main and sub-screens, and after aliasing the image...

Abstract

A device and a method for dynamically displaying the program content of a multi-channel television by a plurality of pictures carry out the dynamical display on the transmitting stream of a multi-channel video with different program sources; the device consists of a tuner 1 and a tuner 2, a selector 1 and a selector 2, a system decoder 1 and a system decoder 2, a message source decoder 1 and a message source decoder 2, a size convertor 1 and a size convertor 2, an aliasing device, an MCU and a buffer; the invention is characterized in that: by utilizing the economical technical means, the displaying modes of PIP and POP of a plurality of pictures of television programs can be realized by adopting the mode of double decoding, the image of Sprite can be displayed dynamically (accurately dynamical), so as to be convenient for the looker to know the playing process of the program on the Sprite in real time and to switch the key frame to the interested channel in time.

Description

technical field [0001] The invention relates to a device and method for simultaneously displaying multi-channel video program source content on a display interface in digital television receiving equipment, in particular to a device and method for dynamically displaying multi-channel TV program content by using multiple pictures. Background technique [0002] With the continuous enrichment of TV program content, especially more and more live TV programs, different TV channels will broadcast live programs at the same time, and the viewer can watch the program content of one TV channel on the same TV and monitor The demand for the progress of the programming content (events) of other channels, the increasing size of the television screen and the continuous improvement of the definition of the television set have made the above-mentioned demands of the viewers even more intense. [0003] In the era of analog TV, there have been TV sets that can display multiple pictures, which ...
