A method and system for performing multi-level searches includes a user device and a display associated with the user device. A guide system receives a content provider category for a first content and receives a global guide category different than the content provider category for the first content. A communication network communicates the global guide category and the provider category to the user device. The user device performs a global search and displays on the display the first content in response to the global guide category and displays on the display a provider homepage with the first content displayed under the content provider category.

The present invention is intended to permit both real-time display of a picture represented by a non-compressed video signal on a television and display of a picture represented by a compressed video signal at any desired time by simultaneously transmitting the compressed video signal and non-compressed video signal via one interface. An STB packetizes a compressed video signal, and multiplexes the compressed video signal and a blanking signal combined with a non-compressed video signal. Thus, both the video signals are transmitted simultaneously. A picture represented by the non-compressed video signal is displayed on a television in real time. The compressed video signal is stored in a storage medium incorporated in the television, read at any user's desired time, and decoded so that a picture represented by the compressed video signal can be viewed at the user's desired time.

This disclosure describes methods and systems for viewing a collection of media objects, such as a video clip and associated responses (video, audio and text), in a seamless way. Provided with a media object and a series of responses and counter responses, a real time media combining methodology is coupled with a text and audio conversion process to generate a media stream, or downloadable media object, that contains the original media object and some or all of the associated responses. The media content is formatted into the stream so that ancillary content, like text associated with a particular video response, may also be displayed. Advertisements may be inserted into the stream between responses or overlaying some portion of the viewing area during rendering of the stream.

The present invention relates to a control device and a control target device, and particularly, to a method for transmitting a content list of a control target device and a control device. A method for allowing a control point device to receive a content list from a control target device, according to one embodiment of the present invention, comprises the steps of: transmitting a content list request message to the control target device; receiving a response message which includes a fragment of the content list; and displaying the content list based on the fragment, wherein the fragment includes a plurality of content objects corresponding to the number of content objects for one content list fragment.

An apparatus, method and data structure for generating at least one table in a broadcast environment, are provided. The apparatus includes a generator to generate an event information table (EIT) and an extended text table (ETT). The ETT has program guide information for an n-hour span and has a transmission interval. The ETT has a transmission interval and program description information according to the EIT. The transmission interval of the EIT is shorter than the transmission interval of the ETT.

The present invention provides a method of transmitting broadcast signals. The method includes, encoding Data Pipe, DP, data according to a code rate, wherein the encoding further includes Low-Density Parity-Check, LDPC, encoding the DP data, Bit interleaving the LDPC encoded DP data, and mapping the bit interleaved DP data onto constellations; building at least one signal frame by mapping the encoded 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.

The invention proposes a method of display of a user interface, that comprises the following steps: a step of display in foreground of a first user interface generated from stored display elements, comprising a first set of display elements providing access to first services, a reception step of a second set of display elements giving access to second services, and a display step of a second user interface in foreground, replacing the first user interface. The invention also relates to a method of transmission of a set of display elements giving access to services, that comprises the following steps: a transmission step of a first set of display elements, giving access to services, and a transmission step of a second set of display elements, giving access to services, and destined to be stored.

A contents receiving system can include a content receiver and a portable terminal storing ID information. The content receiver can further include: a receiving unit capable of receiving content and subsidiary content from at least one of a broadcast wave and a network; an output unit capable of outputting, as audio video content, a video and/or audio of the content received by the receiving unit; a transmission unit capable of transmitting the subsidiary content to the portable terminal, the transmission unit enabling information on a payment transaction corresponding to an ID information of the portable terminal to be transmitted to the portable terminal individually, the portable terminal including: a second transmission unit capable of receiving the subsidiary content and the information on the payment transaction transmitted from the transmission unit of the content receiver; and a processing unit for performing a processing regarding the payment transaction.

The invention relates to a method for transmitting from a server to a client, encoded media data corresponding to a projection of a wide view of a scene, the method comprising: Encapsulating the encoded data into tracks, Wherein information is provided for signaling that the client needs to parse other encoded data to display at least the encoded data encapsulated in a given track.

In accordance with embodiments, a method of transmitting a video includes inter-view redundancy removing pictures for multiple viewing positions; packing inter-view redundancy removed pictures; and/or encoding the packed pictures and/or signaling information including center view generation information, pre-generation information, view synthesis recommendation information and/or reference view information. In accordance with embodiments, a method of receiving a video includes decoding a bitstream of the video based on viewing position and/or viewport information, unpacking pictures in the decoded bitstream; view regenerating the unpacked pictures; and/or view synthesizing the view regenerated pictures.
