System and method to provide a unified video signal for diverse receiving platforms
First Claim
1. A system comprising:
- a processor including;
a data packet generator configured to generate a video data stream including a plurality of data packets based on a received video signal, wherein a first subset of the plurality of data packets is usable to generate a first video display of content having a first quality, wherein a second subset of the first subset is usable to generate a second video display of the content having a second quality, and wherein all of the plurality of data packets are usable to generate a third video display of the content having a third quality, the second quality lower than the first quality and the first quality lower than the third quality; and
a data packet tagger configured to distinguish the first subset of the data packets by applying a first tag to data packets of the first subset to form first tagged data packets and to distinguish the second subset of the data packets by applying the first tag and a second tag to data packets of the second subset to form second tagged data packets; and
a transmitter coupled to the processor and configured to transmit the plurality of data packets of the video data stream.

Abstract
A system includes a signal-processing engine configured to generate a video data stream including a plurality of data packets based on a received video signal. A first subset of the plurality of data packets is usable to generate a video display of content having a first quality and all of the plurality of data packets are usable to generate a second video display of the content having a second quality. The second quality is higher than the first quality. The signal-processing engine is further configured to distinguish the first subset of the plurality of data packets from other data packets of the plurality of data packets by applying a tag to particular data packets to form tagged data packets. The system also includes a transmitter coupled to the signal-processing engine and configured to transmit the plurality of data packets of the video data stream.

10. A method comprising:
-
receiving a video signal at a signal-processing engine; generating, at the signal-processing engine, a video data stream including a plurality of data packets based on the video signal, wherein a first subset of the plurality of data packets is usable to generate a video display of content having a first quality, wherein a second subset of the first subset is usable to generate a second video display of the content having a second quality, and wherein all of the plurality of data packets are usable to generate a third video display of the content having a third quality, the second quality lower than the first quality and the first quality lower than the third quality; distinguishing the first subset of the data packets by applying a first tag to data packets of the first subset to form first tagged data packets; distinguishing the second subset of the data packets by applying the first tag and a second tag to the data packets of the second subset to form second tagged data packets; and transmitting the plurality of data packets of the video data stream. - View Dependent Claims (11, 12, 13, 14, 15)

16. A device comprising:
-
a receiver to; receive a video data stream via a network, the video data stream comprising a plurality of data packets, wherein a first subset of the plurality of data packets is usable to generate a video display of content having a first quality and all of the plurality of data packets are usable to generate a second video display of the content having a second quality, the second quality higher than the first quality, and wherein the first subset of the plurality of data packets is distinguished from other data packets of the plurality of data packets by a tag; identify characteristics of a first display device and a second display device; determine to send the first subset of the plurality of data packets to the first display device based on identified characteristics of the first display device and based on the tag; determine to send the first subset of the plurality of data packets and the other data packets to the second device based on identified characteristics of the second device and based on the tag; and generate copies of the first subset of the plurality of data packets; and a transmitter to send the copies of the first subset of the plurality of data packets to the first display device and to send the first subset of the plurality of data packets and the other data packets of the plurality of data packets to the second device. - View Dependent Claims (17, 18, 19, 20, 21)
