           <p>The Vehicle Information Service Specification (VISS) defines a protocol for accessing vehicle data in a standardized manner. 
             As vehicles become more connected and data-driven, the need for efficient data exchange methods becomes paramount. 
-            Protobuf encoding serves as an efficient solution within VISS due to its compact binary format and schema evolution capabilities.

           <p>In this chapter, we outline the integration of Protobuf encoding with VISS version 3.0, providing comprehensive details on schema definitions, 
             encoding and decoding processes, and practical examples. This will enable seamless implementation and interoperability across different systems and
