A Tutorial on SDTI-CP
This paper begins with a brief review and classification of the current SDTI payload data formats. It continues with a full description of the content package (CP) container format and its mapping onto SDTI (SMPTE 305M).1 The CP, a flexible container format that was developed openly within the SMPTE standards process, marking a welcome departure from the usual process of documenting existing practice. The CP format can be mapped into a file structure for the exchange of program information between disc servers. In this form, it provides the body of the new interchange file format currently under open development in the Pro-MPEG forum. The concept of the CP format was heavily influenced by the EBU/SMPTE Task Force work in the wrappers and metadata subgroup.2 In March 1998, a SMPTE ad-hoc group was formed to study the CP format based on a proposal by Sony. This format was developed from the ground up to carry video, audio, data content, and metadata in a structured manner, initially over the SDTI transport. The paper also describes chip implementation without which complex containers such as the CP could never be a practical reality.
