Recent advances in logic schemes and fabrication processes have renewed interest in using superconductor electronics for energy-efficient computing and quantum control processors. However, scalable superconducting memory still poses a challenge. To address this issue, this disclosure presents an alternative to approaches that solely emphasize storage cell miniaturization by exploiting the minimal attenuation and dispersion properties of superconducting transmission lines to develop a delay-line memory system. The fully superconducting design is operable at frequencies ranging from approximately 20 GHz to 100 GHz and achieves data densities on the order of tens to thousands of megabits per square centimeter. Additionally, the circulating nature of this design allows for minimal control circuitry, eliminates the need for data splitting and merging, and enables inexpensive implementations of sequential access and content-addressable memories.

Systems and methods are described herein for identifying camera angles, based on network parameters, for content available at multiple camera angles. The system determines a network parameter of a network used to provide content that is recorded or rendered at various camera angles. The determined network parameters are used to identify camera angles that are supported by the network. For example, the video data associated with a camera angle having a prerequisite bit rate of 5 Megabits per second is supported by a network having a bandwidth parameter of 40 Mbps, while another camera angle having a prerequisite bit rate of 45 Megabits per second is not supported by the bandwidth parameter of 40 Mbps. The system provides the video data for identified camera angles supported by the network to a device for display.

Methods, apparatus, and systems for forward error correction (FEC) that involves inner and outer zipper codes are disclosed. In some embodiments, a message being sent from a transmitter in a network is encoded with a first zipper code, bits of the message are interleaved, and a second zipper code is encoded. The encoded message can then be sent to a receiver in the network where it is decoded to correct transmission errors. Decoding involves decoding the first and second zipper codes and de-interleaving bits. In some embodiments, one soft decoder and one hard decoder are used, and decoding is performed iteratively. In some embodiments, encoding the first and / or second zipper codes involves excluding some parity bits of the respective zipper code from having copies in that code's virtual buffer.
