DVB Service information functions are required by MHEG5 engine. All required functions should be non-blocking. Functions with a post condition (synchronously returned values) MUST perform quickly, otherwise should copy passed data and return asynchronously through a asynchronous return path, where available. References: [1] DTG UK D-Book 7 part A. [2] Specification for Service Information (SI) in DVB systems ETSI EN 300 468 V1.11.1 Notes: [a] Required functions may or may not use all of the allowed return values, depending on the error handling capabilities of the controlling application implementation.
