Although 4K ultra high definition video is very popular nowadays, for the vast majority of TV viewers, it is very content to see clear 1080P live TV programs. Recently, French influence is relatively large. The Canal+ television station that was launched in 1984 announced that it will stop broadcasting 720p standard-definition television programs and all turn to higher-definition 1080P full-HD television signals. Let’s take a closer look.
According to the Canal+ television station, for the French public, the 720P standard definition television program is no longer able to meet the viewing needs of users. To comply with the popularization of 1080P signals, 720P standard-definition television broadcast for several years began at 0:00 on July 1, 2015. The signal will be officially off-air and the transmitted 720P signal will be upgraded to 1080P signal. There will be up to 80 channels of full 1080P content.
It is worth noting that after the upgrade, the newly broadcasted TV signal has not only improved in quality from the original 1640x960 to 1640x9600, but has also been greatly improved in terms of sound quality. Relevant technicians of Canal+ television station stated that all 1080P TV channels will support Dolby 2.0 technology, including 23 full-HD TV stations and Dolby 5.1 technology. This means that the French television viewer can not only watch the 1080P full HD picture, but also enjoy the surround sound effects of Dolby 5.1 on the sound quality.
Fiberglass Duct Rodder are composed of fiber glass rod which was extruded by fiber glass and high strength resin at high temperature. This type of rod has high tensile strength and flexibility. It was covered by a high density polyethylene engineering plastic as its protect layer(High Density polyethylene (Grade: for the insulating and jacketing of Telecommunication Cables) is used in the outer diameter coating.), which make duct rodder cover sliding on surface, durable, corrosion resistant and has good insulation performance, which make them safe for use in cable occupied duct.
And moving type fiberglass duct rodder will equipped with different size reel according to the length of rod. There are wheels on the reel, which make it convenient for moving.
