Problems solved by technology
[0003] At present, home karaoke is mostly implemented on traditional VCD / DVD and power amplifier equipment, not only the song source is limited, but also it is inconvenient to deploy and carry; most of the home karaoke systems on the market are based on MIDI music, although MIDI music files It occupies a small storage space and has low requirements on the processor. However, the music is synthesized by several musical instruments, the sound quality is poor, and the live effect is not satisfactory. Moreover, a dedicated solidified memory card is used, and the repertoire is limited, which cannot meet user personalization. need

Embodiment Construction
[0021] Such as figure 1 As shown in the embedded network karaoke entertainment device, the sound processing system includes audio processor, mixer / amplifier, reverberation / echo device, connecting microphone and audio equipment, embedded processor (can you name the specific processor used) It is responsible for the control and main processing functions of the whole device, and it is respectively connected with the keyboard, flash memory card like SD card, SDRAM memory, EEPROM memory, Ethernet (network) controller, and video codec. The Ethernet controller is connected to the remote server through the Internet, the video encoder outputs PAL / NTSC or VGA signals, and is connected to an analog TV or digital TV (monitor) for display, and the camera is connected to the video decoder or USB interface. You can also connect peripherals such as headphones and remote controls ( figure 2 ).
[0022] First establish a unified karaoke media file (KAR file) format, and generate a unified ka...

The invention provides an embedded Internet kara OK entertainment device and a method for controlling sound and images thereof, which relate to a household kara OK system. The prior art has the defects of limited song source, user experience homogenization, general audio-visual effect and the like. The entertainment device comprises an embedded processor, an audio processing system, a video coderand a memory. A microphone is connected with the embedded processor through the audio processing system, and the embedded processor is also connected with an Internet controller. When the entertainment device is used, the embedded processor processes a media file in real time to form a dynamic background and scrolling captions and output video signals; and at the same time, the decoded music audios and the microphone reverb audios are mixed and amplified to output audio signals. Because the entertainment device is connected with a remote server through the Internet, when a song needed by a singer is not available in the local memory of the device, a media file of the corresponding song is downloaded from the remote server through the Internet. The entertainment device increases song sources, entertainment and interactivity of the kara OK system and improves user experience and audio-visual effect.
Description
【Technical field】 [0001] The invention relates to a home karaoke system, in particular to an embedded karaoke entertainment device and an audio-visual control method based on networked services. 【Background technique】 [0002] In today's society full of competition and challenges, people's life rhythm is tense and busy, and at the same time, higher requirements are put forward for the time, place and form of leisure and entertainment.
