Description

FIELD OF THE INVENTION The present invention relates to a wireless transmission device for authenticating compressed audio and video files, and more particularly to an audio and video transmission device for encrypting sound and video images to prevent data leakage. Reduce distortion caused by audio and video transmission. Background technique

Everyone is beginning to realize that modern people are inseparable from the world of music and sound. Among them, MP3 is almost a part of the daily life of many people. Unless it is directly played on CDs, the music must be heard. MP3, or other digital music file compression formats, such as ΨΜΑ or AAC, etc., and there are many sources of MP3, it may be directly transcribed from the purchased CD, it may be that a good friend sent by e-mail For you to appreciate, there may be other pipes, but the capacity of MP3 format music files is very small for existing storage devices, and MP3 players can also record multiple music albums at the same time. You can also choose the music you want to include in the MP3 player, which saves you the need to bring a lot of album CDs to choose the music you want to listen to, and the mini style of the MP3 player is easy to carry, because MP 3 Players are not as big as CD stereos, and they are easier to carry than CD players, so after listening to MP3 players, everyone listens to them. And more content than ever, but also through a home wireless network set up, the music broadcast to every corner of the home, and finally we will be rushing to music download site (follow the example of "iTunes Music Store" model) to purchase digital music format.

However, now the record company not only wants to dominate what songs we listen to, but also launches digital copyright management.

( Digi tal Ri ght s Management , DRM ) mechanism, want to stipulate where we listen to music. In terms of the singles, there is D solid, no matter what form the music is consumed, whether it is broadcasted in streaming, broadcast on Internet radio, whether the fans are downloading or buying CDs in the store, musicians are It can be said that it is a matter of course. For the music industry, D painting can make consumers clear Know: The music you buy doesn't belong to you, you just buy (very limited) listening rights.

The Electronic Front ier Foundation proposes a new music consumption model. Music is no longer the price of each individual price, but each user who downloads the service pays a fixed fee. This fee is distributed to each artist according to the number of times the music file is traded on the platform, similar to the radio. The way to pay music usage fees. If the US 60 million exchange file users pay $5 a month, the music industry will earn nearly $3 billion a year (NT$102 billion). The file format can also be applied to all audio-visual entertainment appliances. It is no longer limited to those that the record company has ordered you to buy. It has broken away from the current pricing spells, and the wireless mobile download service will grow substantially. The revenue of large-content services will be 3G networks. Bringing a long drought to the rain.

Therefore, the MP 3 market will be a major industry direction in the future, and it is also a big consideration for improving the future of economic competitiveness. Music is a good medicine for people to adjust their minds. Music can also make people's hearts more calm and cheerful, through MP3. It can make many people hear more songs, enjoy more baptism of music, and also use a lot of good music to drive the society, the country, and the world. SUMMARY OF THE INVENTION No matter CD or MP3, it can be obtained anywhere, through websites, E-mail, wireless transmission, etc., but its copy-protection technology still needs to be strengthened. Its current copy-protection method uses ICs on IC cards. The chip cooperates with the IC card reader to access the IC card's simple API module, which provides easy integration of the IC card during system development, and grants an authorization code IC card to replace the use of the repeated copy of the traditional product serial number. The card's copy protection technology protects your intellectual property rights. There are also RF technologies such as wireless communication and addressing technologies and communication formats such as USB, etc., so it is listed as the current copy-protection method, and the purpose of copy-protection is for the protection of intellectual property rights. In order to protect the intellectual property rights of musicians. However, today's technology people are becoming more and more intelligent, and the technology for cracking copy-protection is becoming more and more powerful. Therefore, it is necessary to add a lot of passwords or special file formats that cannot be copied, so that they can cope with the clever minds of scientific and technological people.

In addition to the improvement of copy-protection technology, if you want to hear better sound quality, you need better The horn or the audio equipment is used to cooperate. Usually, the wiring of the horn between the speakers needs to be connected to the audio equipment such as the horn and the amplifier to provide better sound quality. Nowadays, many families are equipped with a home theater sound system, often sound. There is a considerable distance between the equipment and the horn. The wire often destroys the original home layout. It is also often fixed on the wall by the fixed wire tapping and knocking. This is the disadvantage of the home theater music system; In terms of equipment, if you connect the MP3 to a home theater-style audio speaker or a portable portable speaker, you can get better music quality, but it also has many considerations on the wire, so what you want to solve is It is ideal for wireless transmission to reduce the complexity of the cable configuration. However, the general wireless transmission method is easy to generate sound quality due to interference, or the message is intercepted. Therefore, the wireless transmission encryption is inevitable.
