Adaptive Scene Rendering and V2X Video/Image Sharing
First Claim
1. A method for scene information sharing in a vehicle-to-entity communication system, the method comprising the steps of:
- capturing scene data by an image capture device of an event in a vicinity of a source entity;
determining a spatial relationship between a location corresponding to the captured event and a location of a remote vehicle;
determining a temporal relationship between a time-stamp of the captured scene data and a current time;
determining a utility value as a function of the spatial relationship and the temporal relationship;
determining a network utilization parameter of a communication network for transmitting and receiving the scene data;
applying a selected level of compression to the captured scene data as a function of the utility value and available bandwidth; and
transmitting the compressed scene data from the source entity to the remote vehicle.

Abstract
A method is provided for video sharing in a vehicle-to-entity communication system. Video data is captured by an image capture device of an event remote from a source entity. A spatial relationship is determined between a location corresponding to the captured event and a location of a remote vehicle. A temporal relationship is determined between a time-stamp of the captured scene data and a current time. A utility value is determined as a function of the spatial relationship and the temporal relationship. A network utilization parameter of a communication network is determined for broadcasting and receiving the scene data. A selected level of compression is applied to the captured scene data as a function of the utility value and available bandwidth. The compressed scene data is transmitted from the source entity to the remote vehicle.

12. A vehicle-to-entity communication system having adaptive scene compression for video sharing between a source entity and a remote vehicle, the system comprising:
-
an image capture device of the source entity for capturing video scene data of an event in a vicinity of the source entity; an information utility module for determining a utility value that is a function of a spatial relationship between a location corresponding to the captured event and a location of the remote vehicle and a temporal relationship between a time-stamp of the captured scene data and a current time; a network status estimation module for determining a network utilization parameter of a communication network; a processor for applying a selected amount of compression to the captured scene data as a function of the utility value and the network utilization parameter of the communication network; and a transmitter for transmitting the compressed scene data to the remote vehicle.
