Abstract: Commercial insertion, promo insertion, studio routing, camera switching, tape editing—each of these basic operations involves switching video and audio. We want to continue to perform these operations even as we move from using uncompressed video to using MPEG-2 compressed video, but they are far from trivial. This paper describes the MPEG bitstream constraints required to facilitate switching—or “splicing”—MPEG bit-streams. It also describes the refinements to these constraints that have led to a new standard, SMPTE 312M, Television, Splice Points for MPEG-2 Transport Streams, which specifies bitstream constraints for both seamless and nonseamless splicing. It is ironic that, although splicing is likely the simplest method of switching between MPEG-2 bitstreams, it is probably the most difficult to understand. This paper intends to alleviate the mystery of splicing by explaining the underlying principles clearly so that this simple yet effective technique may be put into wide use throughout the emerging digital television industry.

bio
Norm Hurst has been involved in television research at Sarnoff for 18 years. He has experience in such fields as studio and ENG camera design, CCD camera simulation, and the RCA videodisc project. He has considerable experience using computer simulation for advanced TV system design, and was closely involved with both of Sarnoff's entries in the advanced television testing process, as well as with the Grand Alliance prototype. He implemented the rate control algorithm for the DirecTV prototype uplink encoder, and developed a method for testing set-top decoders for MPEG compliance. Hurst is currently involved in various digital studio projects, including the NIST HD Broadcast Technology Program. He participates in such standards organizations as MPEG. X3L3, the ITU, and, of course, SMPTE. Hurst has 15 patents in the field of television.
