Abstract

The invention provides a playing device which comprises a decoder, an audio and video processing unit, a microprocessor MCU and a display device, and also comprises a plug used for inserting an external TV signal receiving device, a communication port connected with the MCU and used for controlling the external TV signal receiving device connected with the playing device by the plug to receive TV signals and receiving the transport stream (TS) transported by the external TV signal receiving device. The technical proposal provided by the invention ensures that TV manufacturers do not need to integrate a tuner in a television and a user who requires a tuner can otherwise buy the TV signal receiving device to be connected with the playing device by the plug, which reduces the production cost of TV manufacturers and unnecessary expenditure of TV users.

Description

Technical field [0001] The present invention belongs to the field of television technology, and particularly relates to television signal receiving and playing technology. Background technique [0002] With the increasing development of 3C technology, the application of display devices has become more and more extensive, such as monitors as computer output devices, display screens of televisions and monitors, telephone screens, etc. We can see her everywhere in our daily lives. Silhouette. [0003] With the digitization of information, the standardization of transmission, the standardization of interfaces, and the development of integrated circuit technology, computer technology, communication technology, and consumer electronics technology, the so-called 3C technology, have a trend of increasing integration. Along with this process, multiple functions are integrated. All-in-one products came into being. For example, multifunctional mobile phones are used not only for making call...
