“…Such a situation occurs when the spatial area contains an object that is subject to motion between the capture time of the odd and even field, forming a single frame picure. Repetition of such an interlaced picture causes the object repetetively traveling along the trajectory, which is perceived by the viewer as motion judder (van Gassel et al, 2002). The above solutions for trick play are based solely on using resampled video information.…”

“…This information is used to control the output of the video decoder during trick play. The second solution applies signal processing in the compressed domain, avoiding the usage of previous MPEG-2 system signalling information (van Gassel et al, 2002). Although the first solution is described by MPEG-2, its usage is optional and not obligatory (ETSI_TS_101154, 2009).…”

IntroductionDigital video for consumer applications became available in the early 1990s, enabled by the advances in video compression techniques and associated standards and their efficient implementation in integrated circuits. Convergence of transform coding and motion compensation into a single hybrid coding scheme, resulting in various standards in the early 1990s, such as MPEG-1 (ISO/IEC11172-2, 1993), MPEG-2 (ISO/IEC13818-2, 2000) and DV (CEI/IEC61834, 1993). These standards are capable of compressing video at different quality levels with modest up to high compression ratios and differing complexity. Each of the previous standards has been deployed in a digital storage system, based on different storage media. The above hybrid coding schemes, distinguish intraframe and interframe coded pictures. The former, also labelled as I-type pictures, can be independently decoded so that it can be used for video navigation. The latter coding form result in P-type and B-type pictures requiring surrounding reference pictures for reconstruction. The availability of these reference pictures cannot be guaranteed during fast-search trick play, which makes these pictures unsuitable for certain navigation functions. Digital consumer storage standards are equipped with locator information facilitating fast-search trick play. The locator information considers the data dependencies and enables the system entry points for proper decoding. These mechanisms form the basis for selectively addressing coded data and the associated data retrieval during trick play. This chapter discusses trick play for push-and pull-based architectures and elaborates on their implementation for tape, optical and disk-based storage systems. Section 2 introduces traditional and advanced video navigation. Section 3 presents the concepts of low-cost trick play. Section 4 elaborates on trick play for tape-based helical-scan digital video recording. Section 5 discusses trick play in relation with three popular optical-storage systems. Section 6 introduces trick play for push-or pull-based personal video recording deploying a harddisk drive or solid-state disc. The chapter concludes and presents a future outlook in Section 7. Navigation methodsVideo navigation is defined as video playback in non-consecutive or non-chronological order as compared to the original capturing order. Video navigation can be divided into traditional fast forward or fast rewind playback and advanced search methods, which are modern forms of video navigation. The former is found in analogue and digital video recorders. The latter has become possible for random accessible media such as disc and silicon-based memories. This section covers the basic aspects of traditional video navigation and presents two forms of advanced video navigation. The navigation methods are presented without implementation aspects. Implementation aspects will be discussed in consecutive sections addressing tape, optical disk, silicon-based storage solutions. Traditional video navigationFor traditional video n...
