“…To justify our algorithm, the simulation results for the video transmission of the SVC stream with the WPP pre-marking have been compared to the transmission of the SVC sequence without pre-marking (trTCM was configured in blind mode) and the video coded by the H.264/AVC coder with pre-marking based on simple frame type mapping (I,P,B) [9,10]. In all the cases the Foreman video sequence was used.…”

“…In the case of the H.264/ AVC codec which is the widely used MPEG standard for video encoding [18,19] one of the earliest proposed solutions is to include information about the type of frames in the packet classification process [20]. Usually, this method involves the simple frame type mapping (I,P,B) to DCSP values (packet colours) [9,10]. Other popular proposals are based on the analysis of the loss impact of frames or slices on video quality.…”

“…The best WPP configuration is compared with two other scenarios of the video transmission in the DiffServ domain. The first one is the transmission of the pre-marked stream of single layer H.264/AVC video [9,10] and the second one is the transmission of the SVC stream without pre-marking. All the compared solutions were tested at the comparable network configuration and used the same video source.…”

“…It allows to obtain a better perceived video quality than for SVC video transmission without pre-marking. The streaming system employing the WPP algorithm also showed superiority (in terms of the video quality) over the system for the H.264/AVC video transmission with the TypeMapping pre-marking [9,10].…”

The H264/SVC codec allows for generation of hierarchical video streams. In the stream of this type video data belonging to different layers have different priority depending on their importance to the quality of the video and the decoding process. This creates new demands on the mechanisms of packet marking, and thus new challenges for the policy guaranteeing QoS parameters, such as those defined in the DiffServ architecture. Therefore, mechanisms of the traffic engineering used in the DiffServ network should, as far as possible, take into account internal distribution of priorities inside video streams. This may be achieved by implementing an appropriate method for packet pre-marking. The paper describes the Weighted Priority Pre-marking (WPP) algorithm for priority-aware SVC video streaming over a DiffServ network. Our solution takes into account the relative importance of the Network Abstraction Layer Units. It also does not require any changes in the implementation of the DiffServ marker algorithm. The results presented confirm that video transmission in the DiffServ domain, based on the WPP packet pre-marking, can provide better perceived video quality than the standard (best effort) streaming of multilayered SVC video. In addition, a comparison with the transmission of the same video content encoded with the H264/AVC codec also points to the superiority of our proposed method.
