A method for estimating bandwidth between a video server and a video client for playing back a video stream includes video packets. The method involves the following steps performed by the video client: receiving the video packets from the video server wherein the video packets are transmitted by the video server at predetermined time intervals; calculating a difference in a size of the video packets and a difference in a time of reception of the video packets; and estimating the bandwidth based on the calculated difference in size and the calculated difference in the time of reception. The present disclosure further relates to a media player configured to perform the disclosed method.

Systems and methods for addressing a corrupted segment in a media asset. The media guidance application determines that a segment of a media asset is corrupted. The media guidance application determines whether a retrieval period to retrieve an uncorrupted copy of the segment exceeds a threshold period. If the retrieval period does not exceed the threshold period, the media guidance application retrieves and generates for display the uncorrupted copy of the segment. If the retrieval period exceeds the threshold period, the media guidance application determines whether an importance level of the corrupted segment exceeds a threshold level. If the importance level exceeds the threshold level, the media guidance application generates for display a summary for the corrupted segment. If the importance level does not exceed the threshold level, the media guidance application generates for display the subsequent segment and the summary for the corrupted segment in an overlay.

A method for providing a personalized media stream includes receiving a signal from a user to launch a personalized media stream, determining a current time, identifying a first time slot of a schedule into which the current time falls, identifying a first channel that is associated with the first time slot, wherein viewing history for the user indicates that the user has viewed the first channel during the first time slot in the past, automatically tuning the display device to the first channel in response to the signal, receiving, subsequent to the automatically tuning, a command from the user to pause a program playing on the first channel, identifying a second channel associated with a second time slot, wherein the second time slot occurs later in time that the first time slot, and buffering a portion of a program being shown on the second channel during the second time slot.

Information about and access to available third party content are provided via a primary service provider programming guide. A primary service provider may allow its customers/subscribers to access third party content through the systems of the primary service provider upon selection of a given third party content item from the primary service provider programming guide. The third party content may be provided as a full screen overlay over content presently being displayed and viewed from the primary service provider, or the third party content may be provided via a picture-in-picture inset either on the full screen or inside the displayed programming guide. Third party content offered via the primary service provider programming guide may be based on a recommendation of content in view of preferences and profile information for the customer/subscriber.

A method for fetching a content from a web server to a client device is disclosed, using tunnel devices serving as intermediate devices. The client device accesses an acceleration server to receive a list of available tunnel devices. The requested content is partitioned into slices, and the client device sends a request for the slices to the available tunnel devices. The tunnel devices in turn fetch the slices from the data server, and send the slices to the client device, where the content is reconstructed from the received slices. A client device may also serve as a tunnel device, serving as an intermediate device to other client devices. Similarly, a tunnel device may also serve as a client device for fetching content from a data server. The selection of tunnel devices to be used by a client device may be in the acceleration server, in the client device, or in both. The partition into slices may be overlapping or non-overlapping, and the same slice (or the whole content) may be fetched via multiple tunnel devices.

An interactive television program guide system is provided in which a viewer may direct a television to simultaneously display a selected television program and a program guide display. A viewer may use the program guide display to browse available video-on-demand (VOD) while continuing to view a previously selected program in the background. The viewer may browse through video-on-demand programs on the program guide display using a variety of keys on a remote control unit. The viewer may direct the program guide to order a given video-on-demand program/and set a desired broadcast time for that program.

A method for transmitting services information in a broadcasting network by at least one managing center towards a plurality of receivers includes exploring streams broadcasted by a DVB network and streams broadcasted by an IP network and extracting services information from these streams, completing an information table, situated at the highest level in a hierarchy of services information tables, included in the service information DVB-SI transmitted by the DVB network by services information related to the IP network, and transmitting the completed information table in the streams broadcasted by the DVB network towards the receivers having two switchable receiving modules, connected respectively to a DVB and an IP services broadcasting network. The receivers are able to activate the reception of digital data of a service, equivalent to the service currently received, with a second receiving module when receiving conditions of a first receiving module are degraded.

Systems and methods for providing blackout support in video mosaic environments are disclosed. In response to receiving a request for a video mosaic page, screen data, which may include blackout information, is received. The screen data identifies the video assets in the video mosaic page. A determination is made, based at least in part on the screen data, whether any video assets in the video mosaic page should be blacked out. Blacked out assets may be masked and their associated audio blocked. In addition, an overlay of options associated with the blacked out asset may be presented. The overlay may include options to substitute the blacked out asset with replacement content, search for similar content, or retrieve more information about the blackout.

The present invention provides a method of transmitting broadcast signals. The method includes, formatting input streams into Data Pipe (DP) data, Low-Density Parity-Check (LDPC) encoding the DP data according to a code rate, bit interleaving the LDPC encoded DP data, mapping the hit interleaved DP data onto constellations, building at least one signal frame including the mapped DP data, and modulating data in the built signal frame by an Orthogonal Frequency Division Multiplexing (OFDM) method and transmitting the broadcast signals having the modulated data, wherein the input streams include Audio/Video (A/V) data and service guide data, and wherein the Audio/Video (A/V) data and service guide data are included in first ISO base media file format (ISOBMFF) files.
