Patent number: 11388629Abstract: The ATSC 3.0 physical layer broadcast standard is extended with new OFDM numerology, L1 signaling and frame structure aligned with 5G. This is done to enable improved broadcast mobility and convergence 5G release 16 as a Non-3GPP access network. The 5G core network and Broadcast core network interwork over defined interfaces to enable convergence layer 3. This enables improvements of broadcast physical layer for physics of broadcast. The 5G unicast physical layer is enhanced for physics of unicast, and then both are converged at layer 3. This is novel and has many benefits compared to the legacy LTE broadcast method (e.g., Evolved Multimedia Broadcast Multicast Services (eMBMS)), which combines both broadcast and unicast into a single shared LTE frame at layer 1. The eMBMS method is then improved for dominate unicast mode in shared L1 frame. The result is the broadcast performance and efficiency in eMBMS are less than optimal.Type: GrantFiled: November 27, 2019Date of Patent: July 12, 2022Assignee: Sinclair Broadcast Group, Inc.Inventors: Michael J.

Patent number: 10652624Abstract: A Next Generation Broadcast Platform (NGBP) is disclosed that utilizes 5G software-defined networking (SDN) and network function virtualization (NFV) technologies. The NGBP is designed to enable a new paradigm for broadcasters, wherein the model of fixed wireless spectrum access granted only to the licensees of the spectrum is replaced by a flexible model in which licensed spectrum is pooled together and allocated dynamically to broadcast licensees as well as outside tenants. The NGBP is implemented using SDN/NFV technology, and includes a broadcast market exchange (BMX) entity that allocates the spectrum between tenants based on service level agreements (SLAs) with those users. The NGBP also includes an internet protocol (IP) core and a broadcast centralized radio access network (BC-RAN) which apply the major network functions to broadcaster content in accordance with the determinations of the BMX.Type: GrantFiled: April 6, 2017Date of Patent: May 12, 2020Assignee: Sinclair Broadcast Group, Inc.Inventors: Michael J.

Patent number: 10568026Abstract: An example method for notifying a battery-powered device of the presence of high priority broadcast content while enabling the device to conserve battery power includes generating a high priority broadcast signal. The signal includes a high priority symbol identifier for informing the battery powered device to switch from an idle state to an acquisition state to inspect the remainder of the high priority broadcast signal. The signal further includes a high priority indication symbol for informing the battery powered device to transition to an active state from the acquisition state to receive high priority broadcast content before returning to the idle state. The signal further includes a timing symbol for informing the battery powered device of the minimum time period until a next a high priority broadcast signal should be expected, enabling the battery powered device to remain in the idle state until the next high priority broadcast signal.Type: GrantFiled: March 24, 2016Date of Patent: February 18, 2020Assignee: One Media, LLCInventors: Michael J.

Patent number: 10560756Abstract: A new television broadcast model called a Broadcast Market Exchange (BMX) eliminates the inefficiency in spectrum usage, providing maximum flexibility in delivering content through either VHF (for fixed location receiving devices) or UHF (optimized for mobile receiving devices) transmission/propagation. In conjunction with the BMX, a wireless communications system architecture is provided to enable a broadcast augmentation channel. The augmentation channel provides supplementation of the Quality of Service (QoS) of a one way User Datagram Protocol (UDP) delivery environment. The augmentation channel may be comprised of one or more physical delivery mechanisms (wired or wireless), but can be effectively unified for increasing QoS and or scalable levels of service (additional essence) to improve the user experience.Type: GrantFiled: November 10, 2017Date of Patent: February 11, 2020Assignee: Sinclair Broadcast Group, Inc.Inventors: Mark A.
