Abstract

The invention discloses a digital media circuit system based on a MIPS architecture TV SoC chip, comprising: a processor based on the MIPS architecture in the TV SoC chip; The digital media file played by the picture frame is sent to the processor; the audio and video decoder; the processor is connected to the audio and video decoder signal; the audio and video decoder is a built-in special audio and video decoding of the TV SoC chip The audio and video decoder is also used for decoding and playing back the digital media files; the present invention embeds the functions of electronic digital signage and electronic picture frame into the TVSoC hardware circuit based on the MIPS architecture CPU, by means of the TV SoC chip Its own audio and video decoder decodes and plays back media files, which has low cost and high software operation efficiency.

Description

technical field [0001] The invention relates to the technical field of digital media, in particular to a circuit system implemented by a TVSoC chip using a MIPS architecture CPU, and a digital media playing device and method including the circuit system. Background technique [0002] At present, electronic digital signage (Digital signage) and electronic digital frame (Digital frame) with network intelligence functions have the function of receiving multimedia audio and video programs released through the Internet, but the currently popular intelligent electronic digital signage or electronic digital frame The internal information receiving and display circuit system of the system is a hardware circuit designed by a general-purpose CPU and runs its application program based on the operating system of Android or Windows. Because the operating system of Android or Windows needs to run on the CPU hardware system with high cost ( For example, a hardware circuit system composed o...
