    摘要: This invention concerns the transmitting and receiving of digital media packets, such as audio and video channels and lighting instructions. In particular, the invention concerns the transmitting and receiving of redundant media packet streams. Samples are extracted from a first and second media packet stream. The extracted samples are written to a buffer based on the output time of each sample. Extracted samples having the same output time are written to the same location in the buffer. Both media packet streams are simply processed all the way to the buffer without any particular knowledge that one of the packet streams is actually redundant. This simplifies the management of the redundant packet streams, such as eliminating the need for a “fail-over” switch and the concept of an “active stream”, The location is the storage space allocated to store one sample. The extracted sample written to the location may be written over another extracted sample from a different packet stream previously written to the location. These extracted samples written to the same location may be identical.

    摘要: This invention concerns the transmitting and receiving of digital media packets, such as audio and video channels and lighting instructions. In particular, the invention concerns the transmitting and receiving of redundant media packet streams. Samples are extracted (556) from a first (904) and second (906) media packet stream. The extracted samples are written to a buffer (910) based on the output time of each sample (556). Extracted samples having the same output time are written to the same location in the buffer. Both media packet streams are simply processed all the way to the buffer without any particular knowledge that one of the packet streams is actually redundant. This simplifies the management of the redundant packet streams, such as eliminating the need for a “fail-over” switch and the concept of an “active stream”. The location is the storage space allocated to store one sample. The extracted sample written to the location may be written over another extracted sample from a different packet stream previously written to the location. These extracted samples written to the same location may be identical.

    摘要: A networked system is provided for transporting digital media packets, such as audio and video. The network includes network devices interconnected to send and receive packets. Each network device can receive and transmit media signals from media devices. A master clock generates a system time signal that the network devices use, together with a network time protocol to generate a local clock signal synchronized to the system time signal for both rate and offset. The local clock signal governs both the rate and offset of the received or transmitted media signals. The system, which can be implemented using conventional network equipment enables media signals to be transported to meet quality and timing requirements for high quality audio and video reproduction.

    摘要: This invention concerns the transmitting and receiving of digital media packets, such as audio and video channels and lighting instructions. The network (104) is comprised of at least a transmitter device (110) and a receiving device (112). The controllers (122) and (126) of these devices handle the exchanging of configuration messages between the devices (110) and (112). Using the invention, the user is not required to manually configure the processor to receive media packet streams. Instead, a controller (126) of a receiving device (112) operates to receive information on a user selection of media channels and automatically configure the processor of the transmitter device. Further, the receiving device (112) is able to receive media channels using both unicast and multicast protocols. Media channels can be given textual labels which are unique on the unique (104) and easily identify to the user the actual source of the media channel. Media channels of different formats to be sent on the same net work simultaneous. Further, redundant media channels are easily accommodated.
