In a method for transmitting video for a display panel between a transmitter in electronic communication with a receiver over a wireless communication channel, the method includes: receiving, by a transmitter, a data signal from a data source; receiving, by the transmitter, a return signal from a receiver; encoding, by the transmitter based on the return signal, the data signal utilizing a plurality of encoder blocks to generate a layered encoded data stream, wherein a first encoder block encodes the data signal and each subsequent encoder block encodes a difference between an input of a preceding encoder block and an output of a quantizer of a preceding encoder block; and transmitting, by the transmitter, the layered encoded data stream to the receiver for decoding and display on the display panel.

Decoder retrieval timing information, ROI information and tile identification information are conveyed within a video data stream at a level which allows for an easy access by network entities such as MANEs or decoder. In order to reach such a level, information of such types are conveyed within a video data stream by way of packets interspersed into packets of access units of a video data stream. In accordance with an embodiment, the interspersed packets are of a removable packet type, i.e. the removal of these interspersed packets maintains the decoder's ability to completely recover the video content conveyed via the video data stream.

The present disclosure relates to an image processing device and method which are capable of suppressing a reduction in an increase in coding efficiency. A receiving unit that receives an encoded bitstream including a syntax element related to an inter-image process and an analyzing unit that analyzes the syntax element received by the receiving unit in a state in which a value of the syntax element is restricted when the bitstream is a bitstream encoded based on a profile for encoding a still image are provided. For example, the present disclosure can be applied to an image processing device.

Systems and methods for error detection in video data is described. An encoding computing system can receive a video frame. The encoding computing system can encode and decode the video frame based on an encoding scheme. The encoding computing system can generate a frame error detection code for the decoded video frame based on an error detection code generation scheme. The encoding computing system can send the encoded video frame and the error detection code to a decoding computing system. The decoding computing system can decode the encoded video frame and generate a second error detection code using the code generation scheme. The decoding computing system can detect that the decoded video frame is corrupted by comparing the error detection code and the second error detection code.

In example implementations, a method executed by a processor is provided. The method determines an amount of video information that is lost in a video frame due to compression. A drift correction is applied to the video frame to add back a percentage of the amount of video information that is lost. The video frame is encoded with the drift correction.
