Wireless and high-definition are undoubtedly the focus of attention in today's technology era, and have attracted people's attention and discussion. In the application of high-definition information distribution system, wireless high-definition video transmission technology has also become a trend, and continuous technology upgrades to meet wireless high-definition video transmission technology. Demand, improve the application experience of video conferencing equipment.
How is wireless HD video transmission technology generated?
Since wireless high-definition video transmission has become popular in modern enterprise video conferencing, people pay more and more attention to the layout of enterprise video conference rooms. The connection between TV, DVD player, projector and audio is often complicated and cumbersome. It is incompatible with the decoration of the video conference room, especially the placement of speakers in the home theater. It is more difficult to deal with the connection between the host and the host.
However, more and more connections between the complex devices required to support high-definition video conferencing are coming, and the Sony LF-W1BR adopting the IEEE 802.11 b/g wireless LAN transmission standard has not been able to fully cope with it. The transmission rate on it is not very high, so the new wireless HD video standard has also begun to brew. Finally, the two major alliances of WirelessHD and WHDI launched a new wireless HD video standard in 2008, which indicates that it will say goodbye to the connection between the various complex devices needed to support high-definition multimedia home theater. However, the new technology and new standards also have its limitations - there is no strong wireless wall penetration capability, which is also compared with the Sony LF-W1BR.
Advantages of wireless HD video transmission technology:
The wireless HD video standards introduced by WirelessHD and WHDI use 60 GHz and 50 GHz respectively. In the transmission process, they are all transmission methods using one-way transmission. For example, a broadcast device such as a Blu-ray player is used for signal transmission; a display device such as a flat-panel TV or a projector is responsible for signal reception. Compared with the IEEE 802.11 b/g wireless LAN transmission standard adopted by the current popular Sony LF-W1BR, the data transmission rate of the two standards is higher, which is much higher than the 54Mbps of the Sony LF-W1BR, which can meet the 1080P uncompressed. The high-definition video needs wireless transmission, and the current standard can only transmit 1080i high-definition digital signals. However, the transmission distance covered by the Sony LF-W1BR and the high penetration capability of the signal are also desirable for electronic products with new standards.
Since the two standards have a large bandwidth in the transmission process, this feature can display high-quality, high-definition, uncompressed, lossless video, and thus many manufacturers are coveted.
Good product compatibility is also a major advantage of the new wireless HD transmission technology.
The future development of wireless HD video transmission technology憧憬:
With the popularity of high-definition devices such as high-definition flat-panel TVs, high-definition DVD players, and high-definition projectors, the current corporate video conferencing has entered the high-definition era. However, the current wireless technology is also driven by the strong momentum of HD. The emergence of new wireless high-definition transmission technology has led to the emergence of wireless high-definition transmission digital interfaces. The change of interface technology from "real" to "virtual" also indicates that the types of interfaces will be more and more.
The emergence of wireless high-definition transmission technology has mainly solved the connection problem between more and more complex devices required to support high-definition multimedia home theater. With it, the connection cables for various video conferences can be omitted. This makes its HD video conferencing products a huge potential demand for some time to come.
