Methods, apparatuses, and computer program products for overlaying multisource media in VRAM are described. The primary media source is rendered in VRAM by an application program, and then the secondary media source(s) are rendered and blended to the primary source in VRAM at the same location of the primary source in VRAM, so no extra buffer is needed. This improves system performance and reduces power consumption, through reduced system bus, system memory, and CPU usage.

Overlaying multi-source media in VRAM

Methods, apparatuses, and computer program products for overlaying multisource media in VRAM are described.

A data correction apparatus, a data correction method and a tangible machine-readable medium thereof are provided. The data correction method comprises the following steps: receiving a plurality of packets; determining that all of the packets are erroneous packets according to cyclic redundancy check (CRC) information thereof; retrieving any number of pairs among the packets to proceed an exclusive-OR (XOR) logical calculation to generate a plurality of error patterns; obtaining an overall error pattern according to an OR logical calculation of the error patterns; and calculating a correct packet according to one or more of the packets and the overall error pattern.
