Over the years the fidelity and quantity of TV content has steadily increased, but consumers
are still experiencing considerable difficulties in finding the content matching their personal
interests. New mobile and IP consumption environments have emerged with the promise
of ubiquitous delivery of desired content, but in many cases, available content descriptions
in the form of electronic program guides lack sufficient detail and cumbersome human interfaces yield a less than positive user experience. Creating metadata through a detailed
manual annotation of TV content is costly and, in many cases, this metadata may be lost
in the content life-cycle as assets are repurposed for multiple distribution channels. Content
organization can be daunting when considering domains from breaking news contributions,
local or government channels, live sports, music videos, documentaries up through dramatic
series and feature films. As the line between TV content and Internet content continues
to blur, more and more long tail content will appear on TV and the ability to be able to
automatically generate metadata for it becomes paramount. Research results from several
disciplines must be brought together to address the complex challenge of cost effectively augmenting existing content descriptions to facilitate content personalization and adaptation for
users given todays range of content consumption contexts.This chapter presents systems architectures for processing large volumes of video efficiently, practical, state of the art solutions for TV content analysis and metadata generation,
and potential applications that utilize this metadata in effective and enabling ways.

{In large-scale IPTV systems, it is essential to
maintain high service quality while providing a wider variety
of service features than typical traditional TV. Thus
service quality assessment systems are of paramount importance
as they monitor the user-perceived service quality and
alert when issues occurs. For IPTV systems, however, there
is no simple metric to represent user-perceived service quality
and Quality of Experience (QoE).Moreover, there is only
limited user feedback, often in the form of noisy and delayed
customer complaints. Therefore, we aim to approximate the
QoE through a selected set of performance indicators in a
proactive (i.e., detect issues before customers complain) and
scalable fashion.
In this paper, we present service quality assessment framework,
Q-score, which accurately learns a small set of performance
indicators most relevant to user-perceived service
quality, and proactively infers service quality in a single score.
We evaluate Q-score using network data collected from a
commercial IPTV service provider and show that Q-score is
able to predict 60% of service problems that are complained
by customerswith 0.1%of false positives. ThroughQ-score,
we have (i) gained insight into various types of service problems
causing user dissatisfaction includingwhy users tend to
react promptly to sound issues while late to video issues; (ii)
identified and quantified the opportunity to proactively detect
the service quality degradation of individual customers
before severe performance impact occurs; and (iii) observed
possibility to adaptively allocate customer care workforce to
potentially troubling service areas.}
Video email for the digital set-top box

{We describe a prototype, network-based, video email service targeted to run on a variety of thin clients from PCs to digital cable set-top boxes. Email is an attractive starting place for video in the home: (i) it is a familiar means of communicating for many, (ii) its privacy concerns are smaller than for interactive video, and (iii) its "critical mass" requirements may be small since only senders need complete video systems. Nonetheless, most video email systems are still cumbersome in terms of hardware, storage and installation processes. In contrast, our system architecture requires little client storage since the video is streamed to a network-based media server while it is being recorded. The email recipient receives a message that contains a reference to the network-stored video file, and it is streamed down for viewing. We describe the User Experience design challenges associated with implementing the system for digital cable set-top boxes.

System And Method For Generating Coded Video Sequences From Still Media,
Tue Aug 09 16:05:51 EDT 2011
The invention provides a system and method that transforms a set of still/motion media (i.e., a series of related or unrelated still frames, web-pages rendered as images, or video clips) or other multimedia, into a video stream that is suitable for delivery over a display medium, such as TV, cable TV, computer displays, wireless display devices, etc. The video data stream may be presented and displayed in real time or stored and later presented through a set-top box, for example. Because these media are transformed into coded video streams (e.g. MPEG-2, MPEG-4, etc.), a user can watch them on a display screen without the need to connect to the Internet through a service provider. The user may request and interact with the desired media through a simple telephone interface, for example. Moreover, several wireless and cable-based services can be developed on the top of this system. In one possible embodiment, the system for generating a coded video sequence may include an input unit that receives the multimedia input and extracts image data, and derives the virtual camera scripts and coding hints from the image data, a video sequence generator that generates a video sequence based on the extracted image data and the derived virtual camera scripts and coding hints, and a video encoder that encodes the generated video sequence using the coding hints and outputs the coded video sequence to an output device. The system may also provide customized video sequence generation services to subscribers.

Method And System For Aligning Natural And Synthetic Video To Speech Synthesis,
Tue Nov 30 15:05:08 EST 2010
According to MPEG-4's TTS architecture, facial animation can be driven by two streams simultaneously--text and Facial Animation Parameters. A Text-To-Speech converter drives the mouth shapes of the face. An encoder sends Facial Animation Parameters to the face. The text input can include codes, or bookmarks, transmitted to the Text-to-Speech converter, which are placed between and inside words. The bookmarks carry an encoder time stamp. Due to the nature of text-to-speech conversion, the encoder time stamp does not relate to real-world time, and should be interpreted as a counter. The Facial Animation Parameter stream carries the same encoder time stamp found in the bookmark of the text. The system reads the bookmark and provides the encoder time stamp and a real-time time stamp. The facial animation system associates the correct facial animation parameter with the real-time time stamp using the encoder time stamp of the bookmark as a reference.

Scalable Video Encoder/Decoder With Drift Control,
Tue Nov 01 18:10:37 EST 2005
Scalable video coders have traditionally avoided using enhancement layer information to predict the base layer, so as to avoid so-called drift. As a result, they are less efficient than a one-layer coder. The present invention is directed to a scalable video coder that allows drift, by predicting the base layer from the enhancement layer information. Through careful management of the amount of drift introduced, the overall compression efficiency can be improved while only slighly degrading resilience for lower bit-rates.
Flexible interchange of coded multimedia facilitating access and streaming,
Tue Jun 15 18:09:52 EDT 2004
A fundamental limitation in the exchange of audiovisual information today is that its representation is extremely low level. It is composed of coded video or audio samples (often as blocks) arranged in a commercial format. In contrast, the new generation multimedia requires flexible formats to allow a quick adaptation to requirements in terms of access, bandwidth scalability, streaming as well as general data reorganization. The Flexible-Integrated Intermedia Format (Flexible-IIF or F-IIF) is an advanced extension to the Integrated Intermedia Format (IIF). The Flexible-Integrated Intermedia Format (Flexible-IIF) datastructures, file formats systems and methods provide a framework that integrates advanced concepts, such as objects based audio-visual representation, meta-data and object oriented programming, to achieve a flexible and generic representation of the audiovisual information and the associated methods to operate on the audiovisual information.
Flexible synchronization framework for multimedia streams,
Tue Aug 05 18:08:48 EDT 2003
A flexible framework for synchronization of multimedia streams synchronizes the incoming streams on the basis of the collaboration of a transmitter-driven and a local inter-media synchronization module. Whenever the first one it is not enough to ensure reliable synchronization or cannot assure synchronization because the encoder does not know the exact timing of the decoder, the second one comes into play. Normally, the transmitter-driven module uses the stream time stamps if their drift is acceptable. If the drift is too high, the system activates an internal inter-media synchronization mode while the transmitter driven module extracts the coarsest inter-media synchronization and/or the structural information present in the streams. The internal clock of the receiver is used as absolute time reference. Whenever the drift value stabilizes to acceptable values, the system switches back smoothly to the external synchronization mode. The switch has a given hysteresis in order to avoid oscillations between internal and external synchronization modes.

System and method for processing object-based audiovisual information,
Tue Sep 18 18:07:13 EDT 2001
Audiovisual data storage is enhanced using an expanded physical object table utilizing an ordered list of unique identifiers for a particular object for every object instance of an object contained in segments of a data file. Two object instances of the same object in the same segment have different object identifiers. Therefore, different instances of the same object use different identification and the different object instances may be differentiated from one another for access, editing and transmission. The necessary memory required for randomly accessing data contained in files using the expanded physical object table may be reduced by distributing necessary information within a header of a file to simplify the structure of the physical object table. In this way, a given object may be randomly accessed by means of an improved physical object table/segment object table mechanism.
