Abstract: As one example, a system includes a first timestamp generator to provide a first timestamp in response to at least one input clock signal. The first timestamp may be derived based on a global time base and have a resolution that resides within a first range of values corresponding to a first time range. A second timestamp generator provides a second timestamp in response to the at least one input clock signal. The second timestamp may be derived based on a second time base and have a resolution that resides within a second range of values complementary to the first timestamp and corresponding to a second time range that is greater than the first time range. A combiner combines the first and second timestamps to provide a reference timestamp having a value over an extended range of continuous time values.

Abstract: One embodiment includes a system. The system includes a receiver configured to extract a timestamp from a header of each packet of a data stream received from a network and to de-packetize the data stream to provide a stream of data blocks. The timestamp can correspond to generation of each data block associated with each respective packet of the data stream according to a global timebase. The system also includes a delay controller configured to measure a delay associated with each packet of the data stream based on the timestamp relative to the global timebase and to control converting the data stream to a corresponding analog output signal for transmission based on the measured delay.

Abstract: A device can include a stream builder configured to encode media data at a plurality of different coding rates and to generate a plurality of streams encapsulating the encoded media data. Each of the plurality of streams can have an associated protection level that corresponds to an ability of packet reconstruction and a bandwidth cost. The system can also include a stream replicator configured to transmit each of the plurality of streams to a content receiver via N number of networks. The system can further include an adapter configured to control the coding rate and the protection level of each of the plurality of streams based on a feedback signal transmitted from the content receiver. The feedback signal can characterize a packet loss rate of each of the plurality of streams.

Abstract: A system and method of synchronizing transmissions in a simulcast system by continuously adjusting the signal transmission delay. Timing information that includes a GPS timestamp is continuously generated at a source site, encoded into a timing packet which along with a content signal can be transported over a network link such as T1/E1 or a packet switched network to multiple transmitter sites. Once received at a transmitter site, the timing packet along with the content signal is delayed by an adjustable delay. The GPS timestamp in the received timing packet is compared to a GPS timestamp that is generated at the transmitter site upon arrival of the timing packet. Based on a variance between that comparison and the value of a user-specified target delay, the delay of the received signal is adjusted to synchronize signal transmissions in the simulcast system.
