Chrome Multicast Receive API

Multicast Receive API

Subscribes to source-specific multicast IP channels and receives the UDP payloads for that traffic in web applications. This allows web developers to use network and server resources much more efficiently wherever multiple receivers are located inside networks that forward and replicate multicast traffic, whenever transmitting popular data (anything where the same content has to be delivered to many different end users).

Motivation

Currently, Web application developers have no API for receiving multicast traffic from the network. All traffic for web applications thus requires a one-to-one connection with a remote device. Multicast IP provides a one-to-many data stream, and enables packet replication by the network, enabling efficient use of broadcast-capable physical media and reducing load on congested shared paths. Enabling Web applications to receive multicast would solve the receiver distribution problem that contributes to the current under-utilization of multicast on the internet. This effort is coupled with a standardization effort in the MBONED working group at IETF and ongoing trials with multiple network operators to deploy a standardized approach for ISPs to ingest externally sourced multicast UDP traffic.

Chromecast

Chromecast is a digital media streaming adapter developed by Google. The device plays audio/video content on a high-definition television by streaming it via Wi-Fi from the Internet or local network. Users select the media to play on their television from the Google Chrome web browser on a personal computer or from a supported app on their mobile device.

Is Netflix adding a plug-in for Chromebook computers?

Netflix may soon roll out an official plug-in for streaming movies on netbook computers running on Google's Chrome operating system. A version of the plug-in was discovered by an online user. While not fully functional, the plug-in may signal that Netflix is ready to update version 1.0 of the Chrome plug-in, according to this post.

Samsung Chromebook Series 5

Samsung Chromebook Series 5 Review & Rating | PCMag.com

There have been some improvements since Google debuted Chrome OS in the CR-48. For one, Flash support, particularly high-definition videos from YouTube and Hulu, has reaped the benefits of hardware acceleration. Videos played back smoothly and lag-free for the most part, but I would have liked Chrome OS to default to a better video quality than 360p . You have to manually adjust to a higher quality setting. When I say HD support, I really mean 720p max (1080p videos choked in YouTube).

A new media player is also included with Chrome OS plays back actual video and music files, as opposed to streaming them from a Web-based service like Amazon's Cloud Player, Pandora, Slacker, etc. But it's very primitive and the media files will have to come from an external device, such as a USB storage devices or an SD card (through the 4-in-1 media card slot). Chrome OS recognizes external storage devices almost immediately, and you browse through files and folders like you would with Windows. The media player handled 1080p MP4 video files and most audio formats very well, even those that were encoded at high bit-rates. But it also left out a bunch of video formats: The media player isn't compatible with mpeg, AVI, WMV video files, and certainly not Blu-ray.

Video is the future! It's one of the few things I am sure of.

  You would think Chrome OS out the gate would focus on that first and foremost.  Everything else being far easier and less demanding other the maybe 3D graphics rendering.
