    摘要： Methods and apparatus for RF channel switching in a multi-frequency network. In an aspect, a method includes identifying a multiplex set that comprises one or more content flows, wherein the multiplex set is one of a vertical multiplex (VM) set and a unified multiplex (UM) set, generating an overhead message that associates one or more RF carrier frequencies with the one or more content flows, and transmitting the overhead message over the multi-frequency network. An apparatus includes input logic configured to receive an overhead message that associates one or more content flows with one or more RF carrier frequencies, and processing logic configured to detect a channel switch event that identifies a selected content flow, determine a selected RF carrier frequency associated with the selected content flow based on the overhead message, and switch to the selected RF carrier frequency to receive the selected content flow.

    摘要： Embodiments describe a transmit driver that processes data communication between a scheduler and a turbo encoder. Transmit driver receives a request for a super frame and ascertains whether it has enough information to start the super frame. If there is enough data, the super frame is written to an appropriate hardware register. Both Direct Memory Access (DMA) and non-DMA hardware can be supported with the one or more embodiments.

    摘要： This disclosure describes techniques for controlling a perceived quality of multimedia sequences to try to achieve a desired constant perceptual quality regardless of the content of the sequences. In particular, an encoding device may implement quality control techniques to associate a sequence segment with a content “class” based on the content of the segment, determine a perceptual quality metric of the sequence segment, and adjust at least one encoding parameter used to encode the segment is encoded such that for the perceptual quality of the sequence segment converges to the desired quality.

    摘要： Aspects describe a transmit driver that processes data communication between a scheduler and a turbo encoder. Transmit driver receives a request for a super frame and ascertains whether it has enough information to start the super frame. If there is enough data, the super frame is written to an appropriate hardware register. Both Direct Memory Access (DMA) and non-DMA hardware can be supported with the one or more aspects. In an aspect, a method is provided for data transmission. The method includes obtaining data comprising one or more logical channels wherein each of the logical channels comprises one or more code blocks, and wherein each of the code blocks comprises one or more turbo groups, organizing the data based on the one or more code blocks to produce time-sequenced turbo groups, and outputting the time-sequenced turbo groups.
