This specification describes technologies relating to imparting real-time priority-based network communications in an encrypted session. In general, aspects of the subject matter described can be embodied in methods that include establishing, based on cryptographic information in a reserved, random-data portion of a handshake communication, a session, receiving parameter values relating to a sub media stream, included in a header of a network communication, storing the parameter values, obtaining state information and a data payload included in a second network communication, identifying, from the state information, a purpose of the second network communication, and whether a header of the second network communication includes one or more new values corresponding to one or more of the parameters, updating one or more of the stored values based on the one or more new values, and processing the data payload based on the identified purpose and the stored parameter values.

The method and apparatus for distributing digital content includes a local storage medium, a local digital content reader, a remote digital content enabler, and a transmission medium. The local digital content reader transmits a request signal through the transmission medium to the remote digital content enabler requesting an enabler signal to unlock the digital content stored on the local storage medium. The remote digital content enabler processes the request signal and then transmits the enabler signal back to the local digital content reader. The enabler signal enables the local digital content reader to read at least one of the digital contents stored on the local storage medium.

A layer of optically active material overlaps the mode filed of a single mode optical waveguide and has regions to which electric fields can be applied by way of respective electrodes so as to vary the refractive index of the layer in those regions. The regions are spaced apart longitudinally of the waveguide, and the fields are so arranged that they extend at different angles to an interface between the waveguide and the layer and act sequentially upon different polarisation components of radiation propagating along the waveguide. In one arrangement, the fields are orthogonal to one another. In an alternative arrangement, the third field can be applied to a further longitudinally-spaced region of the layer and the three fields are arranged at 120 degrees to one another.

A clock recovery system () for recovering an input data signal () clock. A rate detector () detects the input data signal bit rate and provides range signals (-) specifying progressive ranges encompassing the bit rate. A frequency detector () provides a frequency error signal () based on frequency difference between the input data signal and a recovered clock signal (). A phase detector () provides a phase error signal () based on the input data and recovered clock signals. A filter-controller () provides an oscillator driving signal () based on the range, frequency error, and phase error signals. An oscillator-divider () then provides the recovered clock signal based on the oscillator driving signal and at least some of the range signals. The phase detector, filter-controller, and oscillator-divider collectively thus form a phase locked loop. Optionally, the clock recovery system () may also provide a recovered data signal ().

A pulse width modulated power converter having a single time multiplexed symmetry correction circuit operative to vary the pulse width of output drive pulses applied to an output transformer. As a result, the average current and thus the volt second product seen by each half of the transformer primary winding will be equal under steady state conditions. The transformer drive remains balanced over the entire dynamic range to prevent unwanted saturation of the transformer core.
