H.264 Header Compression Scheme for Wireless Communications

by Z. Ahmad, S. Worrall, A. Kondoz
"... Keywords: H.264 video compression, header compression, video wireless communications A video coding standard with high compression efficiency should have minimum redundancy in the coded bit stream. However, in certain scenario and in particular with small slice sizes, there is significant redundancy ..."
Abstract - Cited by 1 (0 self) - Add to MetaCart
redundancy in form of overheads in the existing coding standards MPEG-4 and H.264. A similar idea of shortened NAL unit header has been recently proposed in the JVT meeting [1]. For small NALU sizes, the overheads may occupy more than half of the video data. Furthermore, large header information renders

Header and unit inference for spreadsheets through spatial analyses

by Robin Abraham, Martin Erwig - In IEEE Int. Symp. on Visual Languages and Human-Centric Computing , 2004
"... This paper describes the design and implementation of a unit and header inference system for spreadsheets. The system is based on a formal model of units that we have described in previous work. Since the unit inference depends on information about headers in a spreadsheet, a realistic unit inferenc ..."

Objects and attention: the state of the art

by Brian J. Scholl - Cognition , 2001
"... What are the units of attention? In addition to standard models holding that attention can select spatial regions and visual features, recent work suggests that in some cases attention can directly select discrete objects. This paper reviews the state of the art with regard to such `object-based &ap ..."

Prosody-based automatic segmentation of speech into sentences and topics

by Elizabeth Shriberg, Andreas Stolcke, Dilek Hakkani-Tür, Gökhan Tür - SPEECH COMMUNICATION , 2000
"... A crucial step in processing speech audio data for information-extraction, topic detection, or browsing/playback is to segment the input into sentence and topic units. Speech segmentation is challenging, since the cues typically present for segmenting text (headers, paragraphs, punctuation) are abse ..."

"... Scalable video coding (SVC) has been standardized as an extension of the H.264/AVC standard. This paper proposes a practical real-time transport protocol (RTP) packetization scheme to transport SVC video over IP networks. In combined scalability of SVC, a coded picture of a base or scalable enhancem ..."
Abstract - Add to MetaCart
enhancement layer is produced as one or more video layers consisting of network abstraction layer (NAL) units. The SVC NAL unit header contains a (DID, TID, QID) field to identify the association of each SVC NAL unit with its scalable enhancement layer without parsing the payload part of the SVC NAL unit

Standardizing Documentation of FITS Headers

by J. A. Hourclé
"... Although the FITS file format[1] can be self-documenting, human intervention is often needed to read the headers to write the necessary transformations to make a given instrument team’s data compatible with our preferred analysis package. External documentation may be needed to determine what the va ..."

A Trade-off between Space and Efficiency for Routing Tables

by David Peleg, Eli Upfal , 1989
"... Two conflicting goals play a crucial role in the design of routing schemes for communication networks. A routing scheme should use paths that are as short as possible for routing messages in the network, while keeping the routing information stored in the processors’ local memory as succinct as pos ..."
Abstract - Cited by 157 (7 self) - Add to MetaCart
(k) of hierarchical routing schemes (for every k z 1) for unit-cost general networks, which guarantee a stretch factor of O(k), require storing a total of O(k. n ‘+(““log n) bits of routing information in the network, name the vertices with O(log’n)-bit names and use O(log n)-bit headers.

Optimizing Header File Include Directives

by Diomidis Spinellis
"... A number of widely used programming languages use lexically included files as a way to share and encapsulate declarations, definitions, code, and data. As the code evolves files included in a compilation unit are often no longer required, yet locating and removing them is a haphazard operation, whic ..."

FPGA-based acceleration of Packet Header

by unknown authors , 2007
"... Abstract. This paper presents an implementation of packet header anonymization unit in FPGA. Packet header anonymization is very important for passive network monitoring, which captures real user traffic and for sharing captured tracefiles, which are valuable resource for networking research. Anonym ..."

The resulting XML ground-truth files list for each table (1) cell contents, (2) relationships between the hierarchical column and row headers and the v ..."
