A broadcast communication system includes a plurality of transmitter tower stations configured to exchange inter-tower communication (ITC) signals to support a wireless ITC network (ITCN). Each TTS includes a transmitter (Tx) antenna, at least one receiver (Rx) antenna, and an ITCN server configured to form outgoing ITC signals for transmitting with the Tx antenna and to process incoming ITC signals received with the at least one Rx antenna. Each of the TTSs is configured to multiplex outgoing ITC signals with broadcast services signals prior to the transmitting and to detect the incoming ITC signals in a wireless signal received with the at least one Rx antenna. Several ITCN-integrating broadcast systems operating in a same or different frequency band may be interconnected to support an integrated inter-tower wireless communication network.

Inter-tower wireless communication network for terrestrial broadcasting systems

A touch display device (TDD) configured to function with a pointing device (PD), and a method of operating the TDD. The TDD has a processor that automatically determines if the PD is in contact with a touch display (TD) of the TDD or with a surface distinct from the TD. When the PD is in contact with the TD, a toggling signal from the PD may be received at the processor to toggle from a first input mode where a tip of the PD overlaps a visual element displayed on the TD, to a second input mode with the tip of the PD is spaced apart from the displayed visual element. When the PD is in contact with the distinct surface, the processor automatically selects a third input mode where a position of the PD on the distinct surface is reproduced as a position the sign on the TD.

Systems and methods to transition between pointing techniques

A primary transmitter of a multicast communication system transmits in-band backhaul to a relay transmitter using an LDM signal that also carries services to end-users. The relay transmitter processes received wireless signal to extract the in-band backhaul and re-transmits services obtained from the in-band backhaul in same or different frequency channel. The in-band backhaul may be transmitted in a high-capacity layer of the LDM signal carrying or in a separate timeslot. Transmitter-specific signature signals may be used for loopback and forward channel estimation at the relay transmitter. The in-band backhaul may also carry service data for devices in a different network.

In-band backhaul with layered division multiplexing

The invention relates to a method of iterative multi-layer decoding of a multimedia communication signal, wherein persistent bits from various upper layers of the employed protocol stack are used in error correction decoding at a lower error-correction layer. The method includes saving persistent bits from successfully decoded FEC frames in memory, and using a subset of the saved bits in decoding of future frames. A smart controller is used to analyze frames for the presence and location of persistent bits, for saving thereof in memory, and for inserting saved persistent bits into a next frame at successive decoding iterations thereof.
