Embodiment Construction

[0079] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0080] Traditional TVs support the picture-in-picture function, and users can still only see one full-screen video content at the same time, which actually wastes the ability of the TV to provide two full-screen videos at the same time.

[0081] In practical applications, DLNA (DIGITAL LIVING NETWORK ALLIANCE, Digital Living Network Alliance) through the development of specifications, so that the main device (usually mobile devices such as mobile phones, tablet PCs and other mobile devices with rich content but limited display area) can discover the DLNA specification in the wireless LAN. Other devices (usually devices with large-screen display functions such as smart TVs) can transmit multimedia resource...

Abstract

An embodiment of the application provides a television signal playing method and device; the method comprises: receiving, by a first terminal, a first television signal and a second television signal; playing, by the first terminal, the first television signal; finding a second terminal by the first terminal; setting, by the first terminal, the first terminal as a digital media server, and the second terminal as a digital media player; transmitting, by the first terminal, the second television signal from the digital media server to the digital media player such that the second television signal is played in the second terminal. The television signal playing method and device according to the embodiment of the application enable two television signals to be played at different terminals respectively, the two television signals are not interfered, picture quality is guaranteed, filtering audio is not required, and playing quality is greatly improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular, to a method for playing a TV signal and a device for playing a TV signal. Background technique [0002] With the development of society, in order to meet people's further demands on the quality of life, terminals tend to play multifunctional TV signals, including picture-in-picture. [0003] Picture-in-picture usually adopts dual high-frequency heads, and the antenna distributor sends a digital TV signal to the secondary high-frequency head. After compression, it becomes a sub-picture of 1 / 9 or 1 / 16 of the original picture size, which is displayed on the screen. corner, while filtering out sound. [0004] That is to say, the compressed sub-picture is inserted on the main picture for normal viewing, so as to monitor other channels while enjoying the main picture. [0005] Due to the limitation of displaying two channels of TV signals on one screen, the two inte...
