    • Systems and methods for multimedia encoding and decoding are disclosed. The systems and methods include multimedia format detection systems, decoder functionality generation systems, decoder instantiation systems, and multimedia processing engines which are capable of selecting a decoder or playback mechanism for each input encoded multimedia stream. The functionality of the decoder or playback mechanism is represented as syntax elements which may be further encoded. The functionality for decoding or playback is then stored or transmitted with the multimedia bitstream. Alternatively, the functionality and multimedia bitstream can be embedded in or associated with a second digital bitstream. Further, the functionality associated with an encoded multimedia stream can be used to instantiate a decoder or playback mechanism and the encoded multimedia stream decoded with the instantiated decoder or mechanism.
    • 公开了用于多媒体编码和解码的系统和方法。 该系统和方法包括多媒体格式检测系统,解码器功能生成系统,解码器实例化系统以及能够为每个输入的编码多媒体流选择解码器或播放机制的多媒体处理引擎。 解码器或回放机制的功能被表示为可以被进一步编码的语法元素。 然后将解码或回放的功能与多媒体比特流一起存储或传输。 可选地,功能和多媒体比特流可以被嵌入第二数字比特流中或者与第二数字比特流相关联。 此外,与经编码的多媒体流相关联的功能可用于实例化解码器或回放机制以及用实例化的解码器或机制解码的经编码的多媒体流。
