“…The slice sorting can also be done as an analytic process as described in [14], which explains the Slice sorting by relevance (SSR) algorithm and how it can be used to prioritize each slice. After the slice sorting in [14], different priority slice partitions are protected with RS codes.…”

Video broadcasting to heterogeneous receivers with varying channel conditions poses many challenges. The nature of the real-time data usually precludes any retransmission option. Forward error correction (FEC) can be used to protect the video data at the cost of adding some redundancy. The gains are increased further by partitioning the video data according to its importance for video reconstruction and adding the redundancy in proportion to the importance. Application Layer Forward Error Correction (AL-FEC) can be applied using rateless codes, which can potentially generate an unlimited number of packets on the fly from the source packets. Expanding Window Random Linear Codes (EW RLC) are a simple unequal error protection fountain coding scheme which can adapt to the prioritized data transmission. In this study we propose EW RLC for DVB-H broadcasting using H.264/Advanced video coding (AVC) slice partitioned data. The results show that EW RLC can be used to protect the slice-partitioned video data for multimedia broadcast applications to suit different data rates and channel conditions.

Abstract-This paper investigates a comparison of transmission schemes for the scalable video over multiple-input multipleoutput relay networks. We consider three time-division multipleaccess cooperative schemes by using embedded space time codes with various degrees of broadcasting and receiving collision. In this paper, we assume that base station and relay station are equipped two antennas and mobile stations have only one antenna. The relay station operates decode-and-forward mode for cooperative transmission. The base station broadcasts scalable video bit stream by encoding embedded space time codes with the assistance of relay. Upon the amount of received information of each cooperative scheme, Mobile stations get the corresponding efficient decoding. With the help of relayed information, base layer retrieves better protection for ensuring the basic quality of scalable video. Visual quality is refined by enhancement layers carried in transmitted signal. We investigate the diversity performance of various schemes in term of bit error rate. Scalable video performance is also provided for comparing and evaluating the effectiveness of scalable video transmission schemes. Based on the need of users, it's possible to select the suitable scheme for trading off between the protection of base and enhancement layers.

“…An UEP is applied on different slices based on their importance. The slice importance is recognized by Slice Sorting by Relevance (SSR) technique, which determines contribution of slices on distortion of the GOP [6,7]. Although this technique provides a reliable performance for the compressed video, it applies a long delay due to sorting slices in one GOP.…”

This paper presents new schemes of Unequal Error Protection (UEP) for video bitstreams compressed by H.264/AVC standard. Proposed UEPs are implemented in two levels. The first level is performed based on specifications of data partitioning recognized as one of the most important and conventional error resilience tools for wireless video transmission systems. The second level is based on determining the size of motion information, which are allocated to the most important partition of a frame or slice. Suitable Forward Error Correcting (FEC) codes with various rates are applied for different partitions according to their importance. Conducted simulations confirm that presented techniques significantly improve performance of video bitstreams, while their overall transmission rates are maintained at the same rate as Equal Error Protection (EEP) technique. Improvements are mainly achieved for videos with the high number of motion information.
