Abstract: The use of a picture delimiter that is contained in a NAL unit type value that is reserved in the current AVC or SVC specification. The present invention provides the scalability information for the H.264/AVC base layer in such a manner that bitstreams remain decodable with H.264/AVC decoders. In addition, the picture delimiter of the present invention may contain many other syntax elements that can help in easier processing of bitstreams compared to the plain H.264/AVC bitstream syntax.

Abstract: A system and method provides a first integrity check code that can be calculated at an encoder and then sent to a decoder as a supplemental enhancement information message. The decoder can then calculate a second integrity check code over the actual received network abstraction layer units. This second integrity check code can be compared with the encoder-generated first integrity check code sent via the supplemental enhancement information message to indicate if in fact all of the transmitted NAL units from which the integrity check code was generated have been received without changes in their content. In addition, an error tracking algorithm is provided that can be run at either the encoder or the decoder in order to determine if the network abstraction layer units are correct in content at the decoder level. Therefore, pictures that are sent as just intra coded frames and pictures that are sent as just inter coded frames can both be checked for errors. Hence, error checking can be provided in those situations where the decoder fails to provide adequate information to the encoder as to what has actually been decoded.

Abstract translation: 系统和方法提供可以在编码器处计算的第一完整性校验码，然后作为补充增强信息消息发送到解码器。 然后，解码器可以在实际接收的网络抽象层单元上计算第二完整性校验码。 该第二完整性校验码可以与通过补充增强信息消息发送的编码器生成的第一完整性校验码进行比较，以指示事实上是否已经接收到从其产生完整性校验码的所有发送的NAL单元，而不改变它们 内容。 另外，提供了可以在编码器或解码器处运行的误差跟踪算法，以便确定网络抽象层单元在解码器级的内容是否正确。 因此，作为仅帧内编码帧发送的图像和仅作为帧间编码帧发送的图像可以被检查错误。 因此，在解码器无法向编码器提供关于实际解码的信息的情况下，可以提供错误检查。

Abstract: A system and method for improving both coding efficiency and decoding accuracy in scalable video coding involving discardable lower layer adaptations, where applications can omit transmission of unused data for inter-layer prediction for all layers below an operation point of receivers. Indicator flags are utilized to avoid transmitting syntax elements that must be set to fixed values.
