Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 As shown, a digital video broadcasting player, a digital video broadcasting player based on an intelligent operating system, includes a receiving module, a tuning module, a demodulation module, a demultiplexing module, a PES analysis module, a CPU, a built-in playback module, and a tuning module The radio frequency signal is received by the receiving module and down-converted to an intermediate frequency signal, and then sent to the demodulation module for demodulation, and the serial or parallel data of the audio and video transport stream is output. The demultiplexing module receives the audio and video transport stream, and extracts the PES data of a program, including video PES, audio PES and data PES. The demultiplexing module includes a descrambling engine, which can descramble the scrambled data at the ...

Abstract

The invention discloses a digital video broadcasting player which is based on an intelligent operation system. The digital video broadcasting player comprises a receiving module, a tuning module, a demodulating module, a demultiplex module, a packet elementary stream (PES) analysis module, a central processing unit (CPU) and an in-built playing module, wherein the receiving module transmits a digital video broadcasting signal to the tuning module, the tuning module samples and decodes a simulated signal, the demodulating module converts the signal into a digital signal stream and then transmits the digital signal stream to a multiplexer, the PES analysis module groups an audio and video PES and outputs a video stream and an audio stream, and the CPU decodes and encodes an audio and a video sequentially and finally outputs the audio and the video. According to the digital video broadcasting player, player hardware and software which meet various digital video broadcasting standards are provided for playing by means of digital video broadcasting standards, the digital video broadcasting player can provide richer digital video broadcasting programs than set top boxes which are used by users at home, and the users can enjoy convenient and rich operation functions on intelligent operation system platforms.

Description

technical field [0001] The invention relates to a digital video broadcasting player, which is a digital video broadcasting player based on a smart phone system. Background technique [0002] With the widespread application of iOS system and Android system in smartphones, multimedia entertainment, and the Internet, they have achieved rapid development due to their ease of use, gorgeous UI, powerful functions, and unlimited software. , computers, and multimedia have a huge impact on people's lives. [0003] A set-top box (the full English name is SetTopBox, referred to as STB) refers to a kind of information equipment used to enhance or expand the functions of a television set. It is a consumer electronics product that allows users to watch and listen to TV and radio programs on existing analog TVs, and to perform interactive digital entertainment, education and commercial activities. Because people usually put it on top of the TV, it is called a set-top box or set-top box. ...
