Embodiment Construction
[0027] The present invention provides a method for realizing multi-software operation and multi-channel decoding and dual-channel high-definition output. The method provides a network server, and the network server provides on-demand software and its initialization files and data, video wallboard software and its initialization Files and data, playback software and its initialization files and data, house number machine software and its initialization files and data, multiple song video files, multiple advertising video files and multiple background video files;
[0028] see figure 1, the present invention specifically comprises the following steps:
[0029] Step 1, after the set-top box is powered on, the first CPU of the set-top box downloads the on-demand software and the video wallboard software from the network server through an exchange chip, the first CPU starts the on-demand software, and the on-demand software passes through the exchange chip. Chip downloads the ini...

The invention provides a set top box with multi-software running and multipath decoding as well as dual-path high-definition output functions. The set top box comprises a first CPU (Central Processing Unit), a second CPU and an exchange chip, wherein the first CPU and the second CPU are both connected to the exchange chip which is further connected to a network interface of the set top box. A realization method of the set top box comprises the steps of: running video on demand software and video wallboard software by the first CPU, running play software and doorplate machine software by the second CPU, completing the communication between a video on demand operation command and video playing through the exchange chip, decoding to output a user operation interface for high-definition graphics, one path of background video stream and one path of advertisement video stream by the first CPU, and decoding to output one path of high-definition song video stream and one path of advertisement video stream by the second CPU, wherein the high-definition song video has high-definition video pictures. According to the invention, the set top box with the simultaneous multi-software running and multipath decoding as well as dual-path high-definition output functions is realized, and the product cost of the set top box is reduced.
Description
【Technical field】 [0001] The invention relates to the field of set-top boxes, in particular to a set-top box which realizes multi-software operation and multi-channel decoding dual-channel high-definition output and a method for realizing multi-software operation and multi-channel decoding dual-channel high-definition output. 【Background technique】 [0002] Most of the set-top boxes currently on the market can only decode and output one high-definition video stream, and output a high-definition GUI at the same time. It is impossible to decode multiple video streams while outputting high-definition video streams and high-definition GUIs, and Existing set-top boxes generally can only run a GUI (Graphical User Interface, Graphical User Interface) software for user-on-demand operations, that is, a set-top box can only be connected to an external TV set for displaying video playback interface and a set-top box for displaying graphics. Touch screen for user interface. [0003] An...
