3D video transmission on a legacy transport infrastructure

The present disclosure relates to a method for transmitting two consecutive pairs of images. The method may include decimating each image with a ratio of 2, assembling the two decimated images of each pair in a composite image, transmitting the composite images, and reconstructing complete images from the composite images. In decimation, the information removed from the images of the first pair may be kept in the images of the second pair, from the spatial point of view, and the complete images may be reconstructed by de-interlacing processing from the composite images.

System and method for remote-hosted video game streaming and feedback from client on received frames

A method and system are provided for streaming a video game from a server to a client. One example system includes the server configured to generate video frames for the video game responsive to input received from the client. An encoder that processes the video frames to generate compressed video frames and storing past encoder states in memory associated with the encoder. The server is configured to transmit the compressed video frames to the client. The server is configured to receive a feedback signal from the client to determine when one or more of the compressed video frames that were sent were not been received by the client. The encoder is configured to generate one or more next video frames as compressed video frames that are dependent on compressed video frames that are known to have been successfully received based on the feedback signal.

The present disclosure relates to transmitting and receiving communications including an upgraded communication quality at a first UE and a second UE. The first UE can determine the first UE is operating using a first RAT. The first UE can also initiate a communication comprising video media between the first UE and a second UE, where a communication quality of the communication is based on the first RAT, where the second UE is operating using a second RAT supporting a higher communication quality than the first RAT. Additionally, the first UE can determine that the first UE is in coverage of the second RAT. The first UE can also indicate, to the second UE, that the first UE is in the coverage of the second RAT. Further, the first UE can adjust the communication quality of the communication to the higher communication quality for the second RAT.
