Q as home gateway engine
Q provides the functionality to
allow a home gateway to intelligently and seamlessly
repurpose audio/video content according to the destination
device (laptop, portable media player, TV, phone,
etc.) and the transport medium (LAN, WiFi, broadband
connection, etc).
Content repurposing is necessary
any time the destination devices does not support
the audio/video format of the source and/or the
transport medium does not support the require bitrates.
Repurposing includes:
- transcoding to a different codec compatible
with the destination
- transrating to a (generally) lower bitrate to
accomodate restrictions on the destination device
- transrating to a lower bitrate to fit within
the bandwidth limits of the transport medium.
- resizing to a (generally) lower resolution to
match a format compatible with the destination
device
Q enables the enhancement of home
gateway to full multi-media home hubs where content
delivery is tailored in real-time to the device
requesting the stream, being it a second TV or portable
media player in the home, a smart-phone or a laptop
outside. |
