HD-DVD may only have an HDMI connector?
For many ready to upgrade AV system, in particular, you are ready to replace TV friends, following the news please pay particular attention! a 21hifi senior editor recently revealed a message that says "next-generation high-definition DVD" HD DVD, Toshiba formation in outgoing upcoming first HD DVD player will not support HD high-definition video output format of the simulation interface, that is to say no now universal video interface output. "HD high definition video" will only provide digital HDMI output! that is to say, even if your plasma, LCD, projection support high-definition, high resolution display, but only the traditional video interface, and there is no HDMI interface, will not be able to fully enjoy the HD DVD of native high-definition picture! actually, before a Toshiba HD DVD player prototype demo Conference, have discovered Toshiba HD DVD which is connected to the HDMI video equipment to play discs, only estimates this is the prototype of the interface may not be complete, so. But it seems now that HD DVD players in all digital transmission standard has been established at that time, just not to disclose it. First is the HDMI can better support for large-capacity data transmission, the English name is HDMI "High Definition Multimedia", Chinese mean high definition multimedia interface. HDMI interface can provide up to 5Gbps data transfer bandwidth, can transmit uncompressed audio signal and high resolution video signal. While not required in the signal transfer before the d/a or die/conversion, can guarantee the highest quality audio and video signal transmission. HDMI supports 5Gbps data transfer rate, transmission distance up to 15 meters, sufficient to meet a 1080p video and an 8-channel audio signal. But because a 1080p video and an 8-channel audio signal needs less than 4GB/s, so there is still great HDMI. This allows it to use a cable to connect the DVD player, receiver and PRR. Besides HDMI EDID and DDC2B, supported an HDMI device with the "plug" characteristics, signal source and display devices automatically "consultations", automatically selects the best video/audio formats. At the same time, HDMI has good security logging, even using HDMI to DVI cable, received a DVI TV watching, but the "HDMI to DVI only correspond with HDCP security video equipment recorded in coding, such as connection without HDCP security video equipment were coding will be no digital video signal output, this allows to illegal high definition bootlegging. At the same time, only have HDMI digital interface for a new round of TV, projection renewal opportunities, promote the tide with family to meet new "high-definition era" replaced the video device. Although equipped with HDMI terminal devices can be backward compatible with DVI terminal device, go through the "HDMI DVI" cable you can connect, but note that the connection method is not necessarily like HDMI terminal directly attached so you can fully transfer the digital audio signal and control signals.
