“…Future work involves optimization of the proposed technique for H.264/AVC switching over combined networks from wireline to wireless links. It should be noted that if VCR-like interactive functions [5] were carried out the performance of the proposed technique could be better improved. This is also a potential research direction.…”

This paper proposes an efficient video stream switching scheme among compressed video streams coded at different quality levels and bit rates. The conventional stream switching scheme in H2.64/AVC is effective in switching, but degrades the compression efficiency of the transmitted stream even if the switching operation does not take place. In the proposed scheme, no modification is made to the original compressed streams so the compression efficiency is maintained at switching points. Consequently switching points can be assigned flexibly in our efficient scheme without noticeable bit rate overhead. It is shown by experimental results that the proposed scheme outperforms the conventional switching scheme.

“…The P(M)-frame encodes the difference between the same video frame and such a difference is almost zero. Actually the P(M)-frame contains codes for not coded Macroblocks and are representing by fixed bit pattern [5]. Hence, it does not require a large number of bits to encode it.…”

In this paper, we present an efficient authenticating mechanism for supporting full interactive functions of video streaming. The server stores multiple versions of the same video for different playback speed. Our mechanism uses a tree-based structure to amortize frame level signature, merges multiple authenticating paths into this structure according to the frame chosen result of the video's different versions, and piggybacks erasure encoded authenticating information on packets. In addition, we analyze its performance compared with traditional tree chaining and erasure coding based schemes. The delay of interactive functions, communication and storage overhead are reduced. Packet loss is also tolerated with high probability.Simulation results further demonstrate the effectiveness of the proposed mechanism.

“…In addition, emerging and future wireless systems will provide sufficient bit rates to support video communication applications. Nevertheless, bit rates will always be scarce in wireless transmission environments due to physical bandwidth and power limitations; thus, efficient video compression is required [1][2][3][4].…”

The H.264/AVC standard introduces enhanced error robustness capabilities enabling resilient and reliable transmission of compressed video signals over wireless lossy packet networks. Those robustness capabilities are achieved by integrating some new error resilience tools that are essential for a proper delivery of real-time video services. Those tools include the Intra Refreshing (IR), Arbitrary Slice Ordering (ASO), Sequence Picture Parameter Sets (PPS), Redundant Slices (RS) tools and Flexible Macroblock Ordering (FMO). This paper presents an error resilient algorithm in wireless H.264/AVC streaming. The proposed method merges Reference Frame Selection (RFS), Intra Redundancy Slice and Adaptive Intra Refreshment techniques in order to prevent temporal error propagation in error-phone wireless video streaming. The coding standards only specify the decoding process and the bitstream syntax to allow considerable flexibility for the designers to optimize the encoder for coding performance improvement and complexity reduction. Performance evaluations demonstrate that the proposed encoding algorithm outperforms the conventional H.264/AVC standard. Both subjective and objective visual quality comparative study has been also carried out in order to validate the proposed approach. The proposed method can be used and integrated into H264/AVC without violating the standard.
