Samsung introduced its SUHD TV lineup for 2015, running on its Tizen OS and using its nano-crystal semiconductor technology. The said the Tizen-based smart TVs will feature more than 700 apps. The 'S' is said to represent the top-end smart TV models from the company.
The new Tizen-based SUHD range will come in three series - JS9500, JS9000 and JS8500 - and in sizes from 48-inches to 88-inches. The SUHD TV JS9500 will feature Samsung's Chamfer bezel design, and a soft, textured Shirring design on the back.

LG
The South Korean consumer electronics giant
announced 'Google Cast for audio', a new streaming technology on the lines of Chromecast that allows s to stream sound from connected devices (smartphones, laptops, and tablets) to Google Cast-ready speakers.
The company said, "We're announcing Google Cast for audio, which embeds the same technology behind Chromecast into speakers, sound bars, and A/V receivers. Just like Chromecast, simply tap the cast button in your favourite music or radio app on Android, iOS, or the web, and select a Google Cast Ready speaker to get the party started."
Google's new Cast for audio is definitely the company's answer to Apple's AirPlay, which also streams audio to AirPlay-enabled speakers.
