At the same time, it is not necessary to perform digital/analog or analog/digital conversion before signal transmission.
HDMI can be combined with Wideband Digital Content Protection (HDCP) to prevent unauthorized copying of copyrighted audio and video content.
The additional space provided by HDMI can be used in future audio and video formats.
And because a 1080p video and an 8-channel audio signal require less than 0.5 GB/s, HDMI has a large margin. This allows it to use one cable to connect the DVD player, receiver and PRR, respectively.
Marking method
HDMI Licensing, LLC released HDMI Specification Version 1.4a on behalf of HDMI Original Development Members on March 4, 2010. Features include key enhancements for 3D applications, the addition of a mandatory 3D format for broadcast content, and a feature called Top-and -Bottom's 3D format.
Because the "HDMI 1.4" argument is too broad to show the specific support technology of the device, the use of the "HDMI 1.4" version numbering method is strictly prohibited in this specification. According to the new "Trademarks and Logo Usage Regulations" released, HDMI cable manufacturers prohibit the use of version numbers when selling and promoting HDMI 1.4 standard cables. Older cables should be removed from all version numbers within one year. Labels, instructions, packaging, etc.
All HDMI devices except cables should be removed from all version numbers prior to January 1, 2012. Prior to this, the manufacturer should apply the version number identification on the premise of clearly displaying the used technology, such as ""HDMI v.1.4 with Audio Return Channel and HDMI Ethernet Channel" (HDMI version 1.4 supports ARC audio feedback channel and HEC Ethernet. Channel), but it is strictly prohibited to use the general "HDMI v.1.4 compliant" (compatible with HDMI 1.4).
Background
In April 2002, Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, Toshiba and seven companies jointly established the HDMI high-definition multimedia interface organization and began to develop a new digital video/audio interface technology that meets the HD era standards. After more than six months of preparation, the HDMI Organization formally released the HDMI 1.0 standard on December 9, 2002, marking the official entrance of the HDMI technology to the historical stage.
The introduction of HDMI technology is not the impulsive behavior of these manufacturers. On the contrary, behind the introduction of HDMI technology, there are still more in-depth reasons.
In April 1999, in order to meet the demand for high-quality graphic images in the digital age, the Digital Display Working Group's Digital Display Working Group was modeled on the patent technology of Silicon Image of the United States and introduced a so-called DVI (Digital Visual Interface). The interface aims to unify the new era digital display interface standards. This technology has also received extensive support from the IT industry with Intel, DELL, HP, IBM, Microsoft and other large companies. After more than three years of promotion, DVI technology has been rapidly applied in the field of computer display output. However, along with the development of digital high-definition audio and video technology, the DVI interface has gradually exposed various problems, even to a certain extent, the progress of digital imaging technology. bottleneck.
The main problems with the DVI interface are:
The object considered by the DVI interface is the PC, and the compatibility with the flat panel TV is general.
The DVI interface lacks support for image copyright protection.
The DVI interface only supports 8-bit RGB signal transmission and does not allow the wide color gamut display terminals to perform optimally.
For compatibility reasons, the DVI interface reserves a lot of pins to support analog devices, resulting in a large interface and low efficiency.
The DVI interface can only transmit image signals, and there is no consideration for the support of digital audio signals.
Due to the above defects, the DVI interface has not been able to better meet the development needs of the entire industry. Therefore, whether it is an IT manufacturer, a flat-panel TV maker, or many publishers in Hollywood, there is an urgent need for a better interface technology that can meet the development of the future high-definition video industry, and it is for these reasons that it has prompted the HDMI standard. The birth.
Technical advantages
HDMI can not only meet the 1080P resolution, but also support digital audio formats such as DVD Audio, support for eight-channel 96kHz or stereo 192kHz digital audio transmission, can transmit uncompressed audio signals and video signals. HDMI can be used for set-top boxes, DVD players, personal computers, video games, integrated amplifiers, digital audio and televisions. HDMI can simultaneously transmit audio and video signals.
HDMI supports EDID, DDC2B, so HDMI-equipped devices have "plug-and-play" features, and signal sources and display devices will automatically "negotiate" to automatically select the most appropriate video/audio format.
Compared with DVI, the HDMI interface is smaller and the HDMI/DVI cable length is less than 8 meters. As long as one HDMI cable, you can replace up to 13 analog transmission lines, can effectively solve the problem behind the connection of the home entertainment system messy.
The dynamic test technology it used has passed the Type 4 functional safety assessment by TUV, and get the national invention patent. The product reaches the advanced technological level of similar products.
BLPS laser safety device provides protection zone near the die tip of the bender to protect fingers and arms of the operator in close to the upper mold die tip. It is the most effective solution so far to preserves the safety and productivity of the bender.
What is the HDMI interface
High Definition Multimedia Interface (HDMI) is a digital video/audio interface technology. It is a dedicated digital interface suitable for image transmission. It can simultaneously transmit audio and video signals with a maximum data transmission speed of 2.25. GB/s
