Systems and methods are described for obfuscating variants of content segments. Variants of content segments can be used to encode an identifying sequence in a transmission of content. The variants of the content segments can each include one or more marked frames and one or more unmarked frames. Variations can be introduced into the unmarked frames for each of the variants of the content segments.

A video processing comprises a video image processing pipeline and an encoder. The video image processing pipeline is processes images of captured video data and comprises: an image stream forming function which generates a first and second image streams each comprising a plurality of image frames, and an image stabilization function for image stabilizing the first image stream, thereby forming a stabilized image stream. The image stream forming function bypasses the second image stream from the image stabilization function, thereby forming an original image stream. The encoder encodes the stabilized image stream and the original image stream as a joint encoded image stream comprising encoded frames based on images frames from both the stabilized \the original image streams, wherein the joint encoded image stream comprises intra and inter frames, and wherein the intra frames are exclusively encoded based on image frames of the original image stream.

Media streaming is contemplated, such as but not necessarily limited to facilitating streaming of audio, video, etc. over networks operating according to Information Center Networking (ICN) principles. The media streaming may be facilitated with a request-response protocol of ICN being leveraged to enable streaming media at infinite scalability without a priori knowledge or guarantee of network resources and bandwidth.

A method is provided that includes receiving pictures of a video sequence in a video encoder, and encoding the pictures to generate a compressed video bit stream that is transmitted to a video decoder in real-time, wherein encoding the pictures includes selecting a picture to be encoded as a delayed duplicate intra-predicted picture (DDI), wherein the picture would otherwise be encoded as an inter-predicted picture (P-picture), encoding the picture as an intra-predicted picture (I-picture) to generate the DDI, wherein the I-picture is reconstructed and stored for use as a reference picture for a decoder refresh picture, transmitting the DDI to the video decoder in non-real time, selecting a subsequent picture to be encoded as the decoder refresh picture, and encoding the subsequent picture in the compressed bit stream as the decoder refresh picture, wherein the subsequent P-picture is encoded as a P-picture predicted using the reference picture.
