AT&T Entertainment and Internet Services CEO John Stankey explained that the new platform would offer "single truck roll installation for multiple products, live local streaming, improved content portability, over-the-top integration for mobile broadband, and user interface re-engineering.AT&T CFO John Stephens had also previously stated that DirecTV's larger subscriber base as a national service gave the service a higher degree of leverage in negotiating carriage deals, thus resulting in lower content costs.Transmissions use digital H.264 (MPEG-4 AVC) encoding, compared to the existing deployments of MPEG-2 codec and the discontinued analog cable TV system.The receiver box does not have a RF tuner, but is an IP multicast client that requests the channel or "stream" desired.The system uses individual unicasts for video on demand, central time shifting, start-over services and other programs.
