Multi-portion radio transmissions
First Claim
1. An apparatus, comprising:
- one or more processing elements configured to;
receive, via a wireless radio, a transport frame of broadcast wireless data that includes;
a plurality of portions, wherein different ones of the portions encode different types of video content; and
control data that indicates the types of video content encoded by the ones of the portions;
select, based on the control data and whether the apparatus is a fixed or mobile device, one or more of the plurality of portions; and
decode the selected one or more portions to determine data represented by symbols in the selected one or more portions.

Abstract
Techniques are disclosed relating to generating and receiving radio frames with multiple portions that have different encoding schemes. An apparatus may include one or more processing elements configured to receive, via a wireless radio, wireless data that includes a plurality of portions that each include multiple orthogonal frequency-division multiplexing (OFDM) symbols. Different ones of the portions have different frequency transform sizes and different sampling rates. The wireless data may also include control data that indicates the frequency transform sizes and sampling rates for the ones of the portions. The apparatus may select, based on the control data and a determined velocity of the apparatus, one or more but not all of the plurality of portions and may decode the selected one or more portions to determine data represented by the OFDM symbols in the selected one or more portions. Different portions of the wireless data may be adapted for decoding by devices moving at different maximum velocities.
