  • System and method for clock drift correction for broadcast audio/video streaming
    Publication number: 20060104397
    Abstract: A clock rate used in rendering broadcast streaming audio/video data is adjusted to converge on a clock rate associated with broadcasting the streaming data. The clock rate is adjusted by monitoring the buffer depth associated with a receive buffer that stores the incoming streaming data. The buffer depth provides an estimate of clock drift between the two clock rates. From the estimate of clock drift, the clock rate used in rendering broadcast streaming data is adjusted to avoid the clock drift causing skips or pauses in the rendered audio/video data.

  • Cross-platform runtime code generation for bit block transfer functions
    Publication number: 20050285869
    Abstract: An exemplary method for performing a bit block transfer (bitblt) includes receiving one or more graphics parameters specifying the bitblt and generating a specialized bitblt function to perform the bitblt. The specialized bitblt function includes a one or more code blocks selected from a superset of code blocks based on the graphics parameters. A system includes a specialized bit block transfer (bitblt) function generator generating a specialized bitblt function to perform a specified bitblt. The specialized bitblt function includes intermediate language code corresponding to one or more graphics parameters specifying the bitblt. A translator translates the specialized bitblt function into machine-specific language code.
