Abstract
Official abstract text for this publication.
Computer program products and a mobile terminal for transmitting and receiving video data. Image data of first and second frames of a video signal captured by a camera is used to determine encoded first spatial units of the first frame and encoded second spatial units of the second frame at lower spatial resolution, which are transmitted to the receiver terminal. The second spatial units are unaligned with the first spatial units due to rotation of the camera between the first and second frames, such that each of the second spatial units partially overlaps with at least one first spatial unit. An indication of the angle of rotation of the camera between the first and second frames is detected using a rotational motion sensor and transmitted to the receiver terminal. The receiver terminal combines the first and second spatial units using the indication to reconstruct an image of higher spatial resolution.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for transmitting video data from a transmitter terminal of a communication system, over a network, to a receiver terminal of the communication system, the system comprising: a processor; and a memory comprising instructions of a communication client for the communication system executable by the processor to perform operations comprising: encoding, on a block-by-block basis, one or more first spatial units at a spatial resolution from image…
