摘要:
A server may receive metadata associated with specific content in a transport signal stream from a content information service. The metadata may identify a point in time of the transport signal stream. The server may instruct an encoder to insert a marker into the transport signal stream corresponding to the point in time of the transport signal stream. The marker may indicate control of a trick mode to be enforced by a delivery platform subsequent to the point in time of the transport signal stream. The server may record the marker in a data store associated with the server.

A tuner device, such as a television set, set top box, game console, personal computer with a dongle or device, creates digital fingerprints indicative of information received over a channel. The digital fingerprints are uploaded to a server along with metadata indicative of the specific tuner device that obtain them. The server maintains a tuner database based on that information, and can automatically request new fingerprints.

A system and method includes an automation system generating a modified content signal from a content signal by inserting insertion material into the content signal during a break and a monitoring system monitoring the content signal. The automation system controls the automation system to return to the content signal in response to monitoring the content signal when the break ends on the content signal before an end of the insertion material.

Methods, devices, and computer program products are provided to enhance viewing of an entertainment content in the presence of advertisements. At a compliant device, an indication is received that the entertainment content is associated with a content policy information relating to presentation of advertisements during, or prior to, presentation of the entertainment content. A further indication is received that the entertainment content is associated with an advertisement award program. An advertisement award program message provides that the advertisements may be presented in a modified form in exchange for a specific number of award points. Upon receiving an indication agreeing to such an exchange, advertisements are allowed to be presented in a modified form. The content policy information can be ascertained through extraction of watermarks embedded in the advertisements or the entertainment content and/or through computation and matching of fingerprints associated with the advertisements or the entertainment content.

A watermark signal provider provides a watermark signal suitable for being hidden in an audio signal when the watermark signal is added to the audio signal, such that the watermark signal represents watermark data. The watermark signal provider includes a psychoacoustical processor for determining a masking threshold of the audio signal; and a modulator for generating the watermark signal from a superposition of sample-shaping functions spaced apart from each other at a sample time interval of a time-discrete representation of the watermark data, each sample-shaping function being amplitude-weighted with a respective sample of the time-discrete representation, multiplied by a respective amplitude weight depending on the masking threshold, the modulator being configured such that the sample time interval is shorter than a time extension of the sample-shaping functions; and the respective amplitude weight also depends on samples of the time-discrete representation neighboring the respective sample in time.

The present disclosure relates to a system and method for monitoring audio-video (AV) streams transported over a network. The system may include an AV probe deployed between an AV tuner and AV destination customer premise equipment. The AV probe may receive an incoming AV stream. The AV probe may generate a thumbnail stream by capturing thumbnails of the incoming AV stream. The AV probe may transmit, substantially in real-time, the thumbnail stream to a monitoring engine and the incoming AV stream to the AV destination customer premise equipment.
摘要:
A computer-implemented method, computer program product, and computing system for receiving one or more transmitted frame identifiers that are mathematical representations of one or more transmitted video frames included within a multi-frame video. One or more video frames included within the multi-frame video are received, thus defining one or more received video frames. A mathematical representation of each of the one or more received video frames is generated, thus defining one or more received frame identifiers. The one or more received frame identifiers are compared to the one or more transmitted frame identifiers to determine a level of similarity between the one or more received video frames and the one or more transmitted video frames.
摘要:
An audio channel of a time-based media presentation provides a basis for synchronizing to the presentation across a variety of platforms independent of when and where the presentation is being viewed. By pre-processing the media into a series of non-unique hashes, and similarly processing an audio stream of the media captured at a client device, a comparison can be made that yields an accurate time offset within the presentation. The comparison may usefully be performed over a data network using a server that hosts data from the pre-processed media, and a variety of applications may be deployed on the client device based on the resulting synchronization.

A closed caption tagging system provides a mechanism for inserting tags into an audio or video television broadcast stream prior to or at the time of transmission. The tags contain command and control information that the receiver translates and acts upon. The receiver receives the broadcast stream and detects and processes the tags within the broadcast stream which is stored on a storage device that resides on the receiver. Program material from the broadcast stream is played back to the viewer from the storage device. Tags indicate the start and end points of a program segment. Program segments such as commercials are automatically replaced by the receiver with new program segments that are selected based on various criteria.

The present invention is an in-train information display apparatus that displays advertisement content to a passenger. The in-train information display apparatus includes a display unit configured to display the advertisement content, a display monitoring unit configured to photograph a video screen which is displayed on the display unit and actually seen from the passenger, and a display-result determining unit configured to calculate color-related information, which is information concerning a color of the video screen, based on an image photographed by the display monitoring unit and determine, based on the calculated color-related information and reference information for display result determination, which is information concerning a color of the advertisement content normally displayed on the display unit, whether the display of the advertisement content has been normally performed.
