    摘要: A video coding system and method that dynamically controls coding parameters to satisfy a resource usage requirement. A resource controller may set parameters or parameter thresholds to change the coding complexity of the video coding system and to effectuate a change in the resource usage rate. Parameters may include the frame rate, the frame resolution, the bit rate, or pixel block sizes. A parameter or parameter threshold adjustment may be based on system resource data, for example, power consumption, CPU usage, fan speed, battery status, input video statistics, coding latency, and other video encoder internal states.

    摘要: A system and method for switching between multiple encoders or decoders may be implemented to quickly and seamlessly transfer coding operations between two encoders. Before switching from a first encoder to a second encoder, the second encoder is initialized and updated with a copy of the necessary information from the first encoder. Similarly when switching from a first decoder to a second decoder, the second decoder is initialized and the necessary information from the first decoder is passed to the second decoder. A controller may monitor the system to identify a condition that would trigger an encoder switch and identify the encoder that best suits the system conditions. According to an embodiment, a shared memory unit accessible by either encoder may store the initialization information. According to an embodiment, a shared decode unit accessible by either encoder may transmit decoded frames between encoders.

    摘要: A system and method for coding video data wherein a coding mode decision process may be dynamically adjusted according to any of a plurality of factors including video image content, image complexity, motion, channel conditions, the status of the video system components, or other relevant factor. Each of a plurality of potential coding modes may be assigned a weight reflecting an estimation of the likelihood that the coding mode will result in quality image data. The coding mode decision process may then be altered by changing the order of coding modes attempted according to the assigned weight. Code removal and early termination may further alter the coding mode decision process.
