Present and future television sets are differentiating each other not only in terms of the quality of the picture and the style of their design, but more and more in terms of their 'intelligence'. Q adds capability that put the Tv at the centre of the home multimedia network.

Modern TV sets can incorporate functionalities that pushes them beyond their original purpose as a display device. As well as including tuners and demodulators, decoders and storage, television sets can add ports for SD/MMC and/or USB flash keys for content transfer (placeshifting, sideloading) and networking chipsets for internet and home-network streaming to/from a wide variety of different devices.
Q enables this new functionality by providing extremely flexible content repurposing.

Key facts:

• TV include home networking chipset
• TV to stream content using one or more of Wireless, Ethernet, Powerline, MOCA, HomePNA, etc.
• Bandwidth contraints change with chosen method
• DLNA allows content publishing to a multitude of devices in home-network
• Missing knowledge of stream recipient demands for flexible transcoding
• Secure reformatting to protect streamed content

The two biggest challenges in designig a TV set (or any other application for that matter) to redistribute decoded content through a home network or the internet for access by another device are the (variable) bitrate contraints imposed by an ever changing medium and the enormous variety of possible destination devices, each with different codec/bitrate/resolution contraints.

The tables below list a few examples of network bandwidths and of destination devices capabilities.

Networking type	Indicative average bandwidth
Internet	2 Mbps
Wireless	20 Mbps
Ethernet	100 Mbps
Powerline	130 Mbps
MOCA	100 Mbps
HomePNA	128 Mbps

Device	MPEG-2	H.264	VC-1	Max Resolution	Max bitrate
uncompressed HDTV				1920x1080	1.5 Gbps
iPod		yes		320x240	768 Kbps
Zune		yes	yes	320x240	736 Kbps
PSP		yes		480x272	1.5 Mbps
Laptop	yes	yes	yes	1920x1080	50-100 Mbps
2nd TV	yes	yes	no	1366x768	20 Mbps
* capabilities for these devices are indicative and depend on both hardware and firmware

Embedded in the TV chipset, Q allows for seamless, real-time content repurposing to a variety of formats and bitrates. Q multi-codec support ensures that the content can be streamed in real-time to any receiving device at a touch of a button or saved to local storage in the most effective format and retrieved for re-delivery afterwards.

For example, HD broadcast signals can be transformed from a 20Mbps MPEG-2 stream to a 8-10 Mbps H.264 stream of the same resolution and stored on internal flash. The content can then be redelivered as a 720p24 5Mbps H.264 stream over wi-fi to a laptop or another TV in the house, as a 480x272 800Kbps MPEG-4 stream to a PSP, etc.
