Signaling of state information for a decoded picture buffer and reference picture lists
Innovations for signaling state of a decoded picture buffer (“DPB”) and reference picture lists (“RPLs”). In example implementations, rather than rely on internal state of a decoder to manage and update DPB and RPLs, state information about the DPB and RPLs is explicitly signaled. This permits a decoder to determine which pictures are expected to be available for reference from the signaled state information. For example, an encoder determines state information that identifies which pictures are available for use as reference pictures (optionally considering feedback information from a decoder about which pictures are available). The encoder sets syntax elements that represent the state information. In doing so, the encoder sets identifying information for a long-term reference picture (“LTRP”), where the identifying information is a value of picture order count least significant bits for the LTRB. The encoder then outputs the syntax elements as part of a bitstream. |

De-juddering techniques for coded video
Judder artifacts are remedied in video coding system by employing frame rate conversion at an encoder. A source video sequence may be coded as base layer coded video at a first frame rate. An encoder may identify a portion of the coded video sequence that likely will exhibit judder effects when decoded. For those portions that likely will exhibit judder effects, video data representing the portion of the source video may be coded at a higher frame rate than a frame rate of the coded base layer data as enhancement layer data. Moreover, an encoder may generate metadata representing “FRC hints”—techniques that a decoder should employ when performing decoder-side frame rate conversion. An encoding terminal may transmit the base layer coded video and either the enhancement layer coded video or the FRC hints to a decoder. Thus, encoder infrastructure may mitigate against judder artifacts that may arise during decoding. |

Compact plasma ultraintense laser
Method for producing ultraintense laser pulses in which Stimulated Raman Back-Scattering (SRBS) amplifies and compresses a seed pulse, as well as an inventive compact plasma device which may implement the method. SRBS may be achieved by counter-propagating the seed pulse and a pump pulse through a few millimeter-long plasma having a plasma frequency equal to the difference between the pump and the seed pulse frequencies. Dichroic mirrors may be arranged to provide two amplifying and compression passes through the plasma, allowing greater seed pulse amplification by mitigating Landau damping within the plasma that would occur in a single pass of a plasma of double the length. Alternate examples provide for 2n number of amplification and compression passes by providing n short plasma columns, where n≥2, and additional, appropriately arranged dichroic mirrors. The compact size of the device, and the ultraintense, ultrashort pulses it emits, suit the device to dermatological applications. |
