niklas-bjorkTranscoder architectures for video coding,” Niklas Bjork  [pictured here] and Charilaos Christopoulos, IEEE Transactions on Consumer Electronics, vol. 44, no. 1 (1998): 88-98. The authors, at Ericsson Telecom AB, Stockholm, Sweden, explain:

“This paper discusses the problem of transcoding H.263-based video streams. Two different models for transcoding are examined, rate reduction and resolution reduction. Results show that the computational complexity of the basic transcoding model can be reduced for each model by, on average, 39% and 23% without significant lose in quality. Comparisons with the scaleable coding model are also shown.”
