1 Video Quality Evaluation for Wireless Transmission with Robust Header Compression Fourth International Conference on Information, Communications & Signal Processing Fourth IEEE Pacific-Rim Conference On Multimedia December 2003, Meritus Mandarin Hotel, Singapore Seeling, Fitzek, Reisslein
2 Content Introduction & Motivation Header Compression Schemes Robust Header Compresion (ROHC) RFC3095 Video over ROHC Methodology and Testbed Setup Results Conclusion
3 Introduction Video services over wireless networks are gaining more and more interest Services are needed that convince customers to buy new equippment (e.g., 3GPP networks) 3GPP networks support video services such as the IMS and the MBMS entities Problem: Video services need much more bandwidth than voice calls, which makes them hard to sell
4 Motivation Video services are transmitted over IP networks using the RTP/UDP/IP protocols Video is encoded efficiently, but the protocol stack overhead is not The protocol overhead comprises a large portion of the traffic (even more for small video formats as for the mobile phones) Therefore: Compression of the protocol overhead needed
5 General Structure of Header Compressors Two entities: compressor and decompressor Compressor sends initial base Base is used by compressor and decompressor Compressor removes redundancy Decompressor adds removed information Proposed solution differ in a possible feedback channel Base Base Compressor N N* Decompressor N
6 IP Header Compression IP HC RFC2507 provides only rudimentary support for UDP with low compression CRTP has problems with high loss rates and delays (bandwidth-delay product) Overall: problems with previous header compression schemes over wireless links
7 Robust Header Compression (ROHC) RFC3095 General ROHC header compression scheme Single hop and stateful Dynamic state and context changes
8 Context states: Robust Header Compression (ROHC) RFC3095 No context: largest ROHC header for context establishment Static context: context for static parts exists Full context: all parts are within the established context
9 Robust Header Compression (ROHC) RFC3095 ROHC modes based on feedback availability Unidirectional mode (no feedback) Periodic context state updates Fallback to lower states upon minor changes Bi-directional optimistic mode Decompressor ACKs context changes NACK based context updates triggered by decompressor Bi-directional reliable mode Closest coupling between compressor / decompressor
10 Methodology Uncorrelated bit errors as recently found for UMTS channels Simulated with and without ROHC implementation O-Mode
11 Metrics Peak Signal to Noise Ratio (PSNR) for quality comparison PSNR = 10log MSE Header Compression, total compression, and mean ROHC header size
12 Testbed Setup
13 PSNR Measurements PSNR calculation is standard metric for objective video quality measurements Freezing for lost frames VideoMeter tool for visualization
14 Netmeter Tool Bandwidth w/o ROHC Bandwidth with ROHC Header compression Overall compression
15 ROHC Results Table of Compression
16 Insights Protocol header compression can be achieved by using ROHC Higher compression ratios for smaller video formats and higher quantization Lower fraction of packets comprised of actual video data (i.e., payload) Lower error probability and state changes within ROHC
17 ROHC Results PSNR Figure
18 Conclusion ROHC is an efficient header compression scheme for multimedia in wireless environments Compression achieved depends on video format and video content Utilization of ROHC for multimedia streaming does not introduce additional losses in terms of perceived video quality (PSNR)
