    摘要: The invention generally relates to multimedia data processing, and more particularly, to processing operations performed prior to or in conjunction with data compression processing. A method of processing multimedia data includes receiving interlaced video frames, obtaining metadata for the interlaced video frames, converting the interlaced video frames to progressive video using at least a portion of the metadata; and providing the progressive video and at least a portion of the metadata to an encoder for use in encoding the progressive video. The method can also include generating spatial information and bi-directional motion information, for the interlaced video frames, and generating progressive video based on the interlaced video frames using the spatial and bi-directional motion information.

    摘要: Methods and apparatus efficiently encode multimedia data, such as live video streams. An encoding complexity of a predetermined time interval, such as 1 second, is estimated before the actual encoding that will be used. This permits the actual encoding to be performed with an a priori estimate of complexity, permitting the bits allocated for the predetermined time interval (bit rate) to be efficiently allocated within the predetermined time interval. Moreover, the estimated complexity can be provided to a device, such as a multiplexer, which can then allocate the available bandwidth for a collection of multiplexed video channels according to the encoding complexity anticipated for those video channels, which then permits the quality of a particular channel to remain relatively constant even when the bandwidth for the collection of multiplexed video channels is relatively constant.
