A Local illumination compensation system for video encoding and decoding uses memory for storing illumination compensation parameters and does not require access to reconstructed pixels of neighboring blocks. A set of illumination compensation parameters is stored in a dedicated buffer, which is of limited size, and which is decoupled from the coding unit level storage of information. The buffer contains a set of illumination compensation parameters, which may be, for example, computed (or determined in some other manner) on the fly or determined beforehand (for example for example obtained from the video signal or from a device).

An apparatus to facilitate video streaming for cloud gaming is disclosed. The apparatus includes a processor to receive a first compressed content bitstream from a first server device; capture input content to utilize as overlay content for the first compressed content bitstream; determine whether one of a first mode of pass-through encoding is enabled or a second mode of look-ahead encoding is enabled; and responsive to the first mode of pass-through encoding being enabled: generate a second content bitstream representing the input content; multiplex the first compressed content bitstream with the second content bitstream to generate a third combined content bitstream; and transmit the third combined content bitstream to a streaming server device for streaming to one or more users.

Provided are a method of buffering a media transport stream in a heterogeneous network environment and an image receiving apparatus using the same. A first transport stream corresponding to a first image through a first network is received and a second transport stream corresponding to a second image through a second network is received. The first image corresponding to the first transport stream is buffered based on a preset minimum transmission delay difference, and then the buffered first image and the second image corresponding to the second transport stream are processed.
