Embodiment Construction

[0018] see figure 1 The signal received by the set-top box passes through the network interface module 1, the demultiplexing module 2, the conditional receiving module 3 and the video and audio decoding module 5 successively, and the received data signal is delivered to the data information processing module 4 after passing through the conditional receiving module 3. In addition, the present invention The set-top box is also provided with an embedded CPU7, which is externally connected with a hard disk 6, a memory 8, a set-top box interface 9 and other peripheral equipment, and the embedded CPU7 communicates with all modules of the set-top box in a bus mode and monitors it.

[0019] The specific functions and structures of each module are as follows:

[0020] Network interface module 1: Complete channel demodulation and channel decoding functions, send out transport stream (TS) containing video, audio and other data information, including wired copper cable HFC interface, Ethe...

Abstract

The invention discloses a set top box. Input signals sequentially pass through a network interface module, a demultiplexing module, a conditional access module and a video/audio decoding module of the set top box and are converted into video/audio signals for output, wherein the output end of the conditional access module is also connected with a data information processing module to output data signals, and the network interface module is provided with a copper wire HFC (hybrid fiber coax) interface, an Ethernet IP interface and an optical fiber OLT (optical line terminal) interface. The settop box combines the television, the broadband and the audio information and can support synchronous realization of video programs, and broadband access and IP telephone in real time. Thus, the invention has high universality and can be combined with more extended functions and services.

Description

technical field [0001] The invention relates to a set-top box, in particular to a set-top box which can be simultaneously applied to TV, broadband network and IP telephone. Background technique [0002] Traditional set-top boxes only realize the reception of video programs, while IPTV set-top boxes realize the integration of video programs and broadband access, and only support single-channel transmission. Video programs and broadband access cannot be realized at the same time, and there is no support for IP phones. Because traditional set-top boxes only realize the reception of video programs, most of them are realized by simple chip circuits, without embedded operating systems, and cannot support the realization of various services and applications, and the software and hardware of set-top boxes are closely integrated, and cannot be realized through software updates. Various applications and business extensions. Defects in the hardware make it difficult to develop applica...
