Embodiment Construction

[0030] see figure 1 , is the logical operation flowchart of the high-definition player of the present invention, and described process mainly comprises, makes system start by power supply switch, and then starts to run Bootloader μ clinux embedded kernel operating system, calls each basic application program of this operating system, and Initialize the entire operating system to return all settings and variables to default values. After the initialization process is completed, the While(1) loop starts immediately to monitor the input signal of the remote control. When a valid input key value is detected, the upper layer UI processing and the corresponding bottom layer processing are started, and these processings are realized through the operation of the internal chip. As a result, return to the While (1) loop after the operation is complete, and wait for a new remote controller to be typed in; if the input signal is an invalid key value, then directly return to the While (1) ...

Various whole ports are integrated to ensure that the high definition player can be applied to ordinary television sets, high definition television sets, VGA displayers and ordinary audio systems, and USB port equipment and Ethernet equipment can be compatible with the high definition player which is controlled by a wireless controller.

Description

technical field [0001] The invention relates to the technical field of electronic applications, in particular to a high-definition player. Background technique [0002] In the mid-1990s, with the rapid development and popularization of the Internet all over the world, people had the idea of ​​surfing the Internet with TV sets, so set-top boxes with Internet networking functions appeared. In November 1998, after the trial broadcast of HDTV (High-Definition TV, high-definition television) in the United States and Europe, another upsurge of set-top boxes was set off. It also has network and conditional access functions. On August 14, 2000, China's digital cable TV program was successfully premiered in Shenzhen. At present, many cities in China have launched digital TV services, and various set-top box markets are gradually expanding. [0003] The IP set-top box uses the relatively mature Ethernet access technology to access the broadband network. After passing the user identi...
