Televes Arantia Live Multiscreen Transcoder and Streamer

Common mobile devices such as smartphones, tablets or PC connect through different networks (NAT networks, Wi-Fi access points, 3G and LTE networks, etc. ), which seldom support network protocols without status control features, like UDP or RTP. For this reason, and also to ensure an appropriate service, the use of TCP-based transmissions is usually a mandatory requirement.

Moreover, this type of networks do not usually provide a guaranteed bandwidth, which produces instability and video streaming (or buffering) cut-outs. By using adaptive streaming, the video stream will dynamically adapt to the network resources available at any given time, thus delivering the highest possible quality.

Another significant advantage of adaptive streaming is the fact that it ensures video playback on any device, since the device itself - based on its resources and limitations - will be requesting the appropriate video stream.

In order to offer this set of services, the use of a Transcoding process is required; it aims at transforming video, audio or any data track streams. This transformation allows for the use of different coding standards, each compliant with different requirements or limitations.

The video transcoding process consists in the intake of video streams, their decoding, their further processing or transformation (resolution, aspect ratio, sampling rate, etc.), and finally their new coding. The audio transcoding process is very similar to the video transcoding process, the difference being that the main transformation processes consist in the re-sampling and the channel mixing.

The equipment can either behave as a transcoder (to adapt channels to the output requirements), a streamer (to deliver the HLS-transcoded contents), or both.

Main Features

• Adaptive streaming: The video quality will dynamically adapt to the network capacity, delivering the highest possible quality at any time.
• HEVC compatibility, allowing for an even higher optimization of the network resources. Primarily designed for use on LTE networks.
• Up to 4k (2160p) output resolution
• Fully scalable: A tool with up to 80 node management capacity. New equipment hot-plug capability.
• Equipment reconfiguration: Depending on the requirements at a given time, the equipment will act as a transcoder, a streamer or both simultaneously, sharing the resources.
• Native multi-device player: The web player is optimized for the use of the HW decoding resources of each specific device, improving performance and optimizing power consumption.
• Casting service-compatible players: The web players on compatible devices allow the sending of contents to casting devices such as Chromecast or AppleTV.
• Responsive web tool: The whole management and configuration of the equipment can be carried out from a web interface that adapts to any device.
