摘要： A system may route media stream samples in time-stamped packets to a media interface. The system may determine a hash value from a stream identifier that identifies a source media stream corresponding to the media stream samples. The hash value may be determined based on a combination of a first portion of the stream identifier and a second portion of the stream identifier. The system may determine whether the stream identifier identifies a subscribed media stream by looking up the hash value in a hash table. The system may route the media stream samples to a media interface if source media stream is a subscribed media stream.

摘要： A network media adapter includes peripheral interfaces for connection to connectors of audio/video (“A/V”) sources and sinks to respectively receive media data from the A/V sources and to transmit media data to the A/V sinks. Components are configured to syntonize or synchronize local media clocks of the A/V sources and sinks to ensure media data integrity affiliated with a protocol of a media network over which the media data is transported. A quality of service (QoS)-compliant media interface is integrated in the network media adapter through which to send and receive processed A/V media data to and from the media network according to the protocol. Other components may be configured to process, encapsulate, and transport over the media network the media data received from the A/V sources. Still other components may be configured to receive media data from the media network and decapsulate, process, and transmit the media data through one or more peripheral interfaces connected to the A/V sinks.

摘要： A system recovers a local media clock from a master media clock based on time-stamped packets received from a transmitter. The packets may include audio, video, or a combination of both, sampled at a rate determined by the master media clock at the transmitter. Timestamps in the packets may be based on values of a remote real-time counter at the transmitter that is synchronized with a local real-time counter at a receiver. The local media clock may be syntonized with the master media clock through the clock periods. The clocks may be synchronized by syntonizing the clocks and adjusting the phase of the local media clocks based on timestamps and a real-time counter.

摘要： A system for memory instantiation in a programmable logic device (PLD) includes a computing device having a processor and memory coupled with the PLD. The processor is configured to receive memory parameters including at least a data width and a data depth. The processor is also configured to determine a number and sizes of block random access memory (BRAM) primitives required for data storage based on the memory parameters and based on one or more sizes of BRAM primitives available on the programmable logic device. In one example, the processor minimizes a size of the total number of BRAMs required for instantiation on the PLD. The processor is also configured to instantiate the determined number and corresponding sizes of the BRAM primitives in logic for configuration of the programmable logic device to include a device memory within the available BRAM primitives thereof corresponding to the determined number and sizes of the BRAM primitives.
