摘要:
Video distribution methods include providing a primary video data stream having a first image size and formatted in a first video display format. A transmission data stream is formed having a plurality of blocks of data including at least first and second data fields. The first data field includes a secondary video data stream extracted from the primary video data stream and is formatted for display in a second video format. The second data field includes supplemental data extracted from the primary video data stream and configured to provide, when combined with the data of the first data field, a tertiary video data stream formatted for display in a third video format. The transmission data stream is multicasted from a wireless communication transmitter to a plurality of wireless communication terminals. Wireless communication terminals and systems are also disclosed.
