Title: | Practical and Scalable Transmission of Segmented Video Sequences to Multiple Players using H.264 | Authors: | QUAX, Peter DI FIORE, Fabian ISSARIS, Panagiotis LAMOTTE, Wim VAN REETH, Frank |
Issue Date: | 2009 | Publisher: | Springer | Source: | Motion in Games: Second International Workshop, MIG 2009, Zeist, The Netherlands, November 21-24, 2009. Proceedings. p. 256-267. | Series/Report: | Lecture Notes in Computer Science LNCS series | Series/Report no.: | 5884 | Abstract: | We present a practical way to distribute viewports on the same video sequence to large amounts of players. Each of them has personal preferences to be met or is limited by the physical properties of his/her device (e.g., screen size of a PDA or processing power of a mobile phone). Instead of taking the naïve approach, in which sections of the video sequence are decoded and re-encoded for each of the clients, we have exploited advanced features offered by the H.264 codec to enable selection of parts of the video sequence by directly manipulating the encoder-generated bitstream. At the same time, we have overcome several practical issues presented by the fact that support for these features is sadly lacking from the state-of-the-art encoders available on the market. Two alternative solutions are discussed and have been implemented, enabling the generation of measurement results and comparison to alternative approaches. | Notes: | Expertise Centre for Digital Media, Hasselt University - tUL - IBBT, Wetenschapspark 2, BE-3590 Diepenbeek, Belgium | Keywords: | Video coding - Transmission - Remote Rendering | Document URI: | http://hdl.handle.net/1942/10563 | ISBN: | 978-3-642-10346-9 | DOI: | 10.1007/978-3-642-10347-6 | ISI #: | 000277818100023 | Category: | C1 | Type: | Proceedings Paper | Validations: | ecoom 2011 |
