Although High Dynamic Range (HDR) content can provide an enhanced immersive experience for end-users, the impact of channel errors on its perception is unclear due to the lack of a standardized HDR video distribution framework. This paper presents an assessment of the robustness of the two main HDR video distribution architectures, the single-layer 10-bit scheme and the two-layer 8-bit backward-compatible...
AC-3 audio compression find applications in home cinema, DVD, BD and digital television. This paper addresses the challenge of transparently watermarking AC-3 bit streams instead of the conventional decoding — baseband watermarking — re-encoding approach. We discuss the alternate possibilities to embed watermarks by altering the MDCT coefficients delivered in the bit stream, which consists of mantissas...
Different system may have different request on coding efficiency and security, even the characteristics of the unreliable networks are fixed, such as bit error rate, packet loss rate and bandwidth. In this paper, a novel multiple description coding (MDC) scheme is presented for the unreliable networks, considering both the network characteristics and system request. An error-resilient problem based...
Scalable video coding (SVC) was recently standardized as an extension of the H.264/AVC standard. A scalable coder allows to combine different layers of spatial, temporal and quality scalability, and is a viable solution for adaptation to user characteristics and network conditions. On the other hand, Multiple description coding (MDC) can provide error resilience and graceful quality degradation for...
