Abstract: Secure functions may be accessed via an authentication process utilizing a password that may be generated within a chip integrated on a device. The password may be unique per chip location, per challenge and/or per chip. The location of the chip may be determined based on GPS information and securely stored and securely communicated to an external entity. Two or more of the chip location, a generated random number sample and a key from a table of keys may be passed to a hash function that may generate a password. An external entity attempting access may be challenged to respond with a password that matches the password generated by the hash function. The response may be compared with the password generated by the hash function and access to one or more secure functions may be granted based on the comparison.

Abstract: A system for transcoding locally cached content may include a memory configured to store at least a video stream. A controller communicatively coupled to the memory may be configured to determine a video definition format of a requested video stream and compare the requested video stream with a video definition format of a cached version of the requested video stream.

If the video definition format of the requested video stream is same as the video definition format of the cached version, the controller may supply the requested video stream using the cached version stored in the memory without transcoding.

Abstract: A method and system for secure and scalable key management for cryptographic processing of data is described herein. In the method, a General Purpose Cryptographic Engine (GPE) receives key material via a secure channel from a key server and stores the received Key encryption keys (KEKs) and/or plain text keys in a secure key cache. When a request is received from a host to cryptographically process a block of data, the requesting entity is authenticated using an authentication tag included in the request. The GPE retrieves a plaintext key or generate a plaintext using a KEK if the authentication is successful, cryptographically processes the data using the plaintext key and transmits the processed data. The system includes a key server that securely provides encrypted keys and/or key handles to a host and key encryption keys and/or plaintext keys to the GPE.

Abstract: Data is written from a first domain to a FIFO memory buffer in a second domain. The first domain uses a first clock signal, the second domain uses a second clock signal and the memory buffer uses the first clock signal that is delivered alongside the data. The data is read from the memory buffer using the second clock signal. A read pointer is adjusted and synchronised with the delivered first clock signal. A token is generated using the delivered first clock signal, based on the read pointer. The token represents a capacity of the memory buffer having been made available. The token is passed to the first domain and synchronised with the first clock signal. The writing of data to the memory buffer is controlled based on a comparison between the synchronised token and a previously received token.

Abstract: There is presented a high bandwidth circuit for high-speed transceivers. The circuit may comprise an amplifier combining capacitor splitting, inductance tree structures, and various bandwidth extension techniques such as shunt peaking, series peaking, and T-coil peaking to support data rates of 45 Gbs/s and above while reducing data jitter. The inductance elements of the inductance tree structures may also comprise high impedance transmission lines, simplifying implementation. Additionally, the readily identifiable metal structures of inductors and t-coils, the equal partitioning of the load capacitors, and the symmetrical inductance tree structures may simplify transceiver implementation for, but not limited to, a clock data recovery circuit.

Abstract: Disclosed are various embodiments directed to transcoding a bit stream in parallel. A bit stream may be divided into a plurality of segments, where a plurality of transcoders encode at least a portion of the segments in parallel. If encoding is performed using variable bit rate (BR) encoding, each encoder may encode a segment and vary a BR for the segment. A measured average BR is compared with a target average BR to determine whether to adjust a video quality level (VQL) or any other encoder parameter. A relatively constant subjective quality may be maintained using variable BR encoding while achieving a target average BR. When using constant BR encoding, a VQL or other encoder parameter is used by encoders to achieve relatively constant subjective quality. For example, a relatively continuous quantization parameter between adjacent encoded segments may be achieved.

Abstract: A method for seamless transition between interlaced and progressive video profiles may include receiving at a video feeder a stream of video signals for displaying on a display device. The stream of video signals may include segments of one of interlaced fields or progressive video frames. During an interlaced stream, the interlaced fields may be directed to a deinterlacer, and an output of the deinterlacer may be directed to the display device. The output of the deinterlacer may be determined based on previously received interlaced fields from the video feeder. During a transition to a progressive stream, the progressive video frames may be directed to a frame store, and the output of the deinterlacer may be directed to the display device. During a progressive stream, the progressive video frames may be directed to the frame store, and previously stored frames may be directed to the display device.

Abstract: A time limit may be determined for energy efficient networking (EEN) sleep intervals based on end-to-end sleep interval limitations. The time limit may be communicated to other network devices which may limit their sleep time. End-to-end sleep interval limitation information may be received via a user input, packet header information, a standardized and/or non-standardized network management protocol, AVB, SRP, RSVP and SNMP. The EEN sleep interval time limit may be determined based on a number of hops between endpoint devices. Packets may be inspected to determine a packet data type and/or end-to-end sleep interval limitation information. The time limit may be determined based on latency requirements of data streams. A time limit for a port may be determined based on sleep time limits for data streams communicated via the port. The time limits may be statically and/or dynamically configured. The network device may be configured via a network management interface.
