用HDMI产品你不了解TMDS怎么行?

date:On November 02, 2017 Source:  

   如今HDMI是个热门话题,网上到处都是HDMI的话题,也有很多用户使用HDMI线,HDMI光纤产品而感悟出来的一些珍贵的HDMI知识,从原理到材质的了解真是用了很多的知识,为什么一条HDMI线就能让大家产生这么多的猜想与讨论呢?

Now HDMI is a hot topic, the Internet is full of HDMI topic, there are many users use HDMI cable, HDMI fiber products and some of the valuable knowledge of HDMI, from the principle to the understanding of the material is really a lot of knowledge, why an HDMI Line can let everyone produce so much guess and discussion?


   无论是HDMI线,还是HDMI光纤都给了很多的用户留下了深刻的印象,不单单是传输过程的稳定性还是高清的输出模式,都深深的震撼到了大家,所以才有那么多得感悟,可是在HDMI中还有一个种可以讨论的知识,就是TMDS,这种技术在HDMI和DVI是比较常见的,今天就来了解了解。

Whether it is HDMI cable, or HDMI fiber has given a lot of users left a deep impression, not only the stability of the transmission process or high-definition output mode, are deeply shocked to everyone, so have so much insight , But there is a kind of HDMI can discuss the knowledge, that is, TMDS, this technology in HDMI and DVI is more common, and today to understand the understanding.


   HDMI采用和DVI相同的传输原理——TMDS(TransitionMinimizedDifferentialsignal),最小化传输差分信号。TMDS支持高达225MHz的传输速率,一个传输链路能满足高达2048*1536分辨率的电视信号。

HDMI uses the same transfer principle as DVI - TMDS (TransitionMinimizedDifferentialsignal), minimizing the transmission of differential signals. TMDS supports up to 225MHz transfer rate, a transmission link to meet up to 2048 * 1536 resolution TV signal.


   TMDS的原理-TMDS principle


   每一个TMDS链路都包括3个传输RGB信号的数据通道和1个传输时钟信号的通道。每一个数据通道都通过编码算法,将8位的视、音频数据转换成最小化传输、直流平衡的10位数据。这使得数据的传输和恢复更加可靠。最小化传输差分信号是通过异或及异或非等逻辑算法将原始8位信号数据转换成10位,前8为数据由原始信号经运算后获得,第9位指示运算的方式,第10位用来对应直流平衡。

Each TMDS link includes three channels that transmit RGB signals and one channel for transmitting the clock signal. Each data channel through the encoding algorithm, the 8-bit video and audio data into a minimum transmission, DC balance of 10-bit data. This makes data transmission and recovery more reliable. Minimize the transmission differential signal is through the XOR and XOR logic algorithm to the original 8-bit signal data into 10 bits, the first 8 for the data from the original signal after the operation obtained, the first nine instructions to operate the way, the first 10 Used to correspond to DC balance.


   这就是TMDS的原理,今天就讲解了一小小的部分,如果还想了解更多的HDMI知识每天就在利诺威官网留意最新资讯。

This is the principle of TMDS, today to explain a small part, if you want to know more about HDMI knowledge every day in the Lenewei official website attention to the latest information.
