A video-on-demand server, having a plurality of audiovisual assets stored in association therewith, and an application server module, are interconnected with a first group of consumer premises equipment (CPE) associated with a first group of subscribers and a second group of CPE associated with a second (different) group of subscribers, via a video content network. The application server module, the first group of CPE, and the second group of CPE are cooperatively configured to prepare a first video-on-demand catalog comprising a first group of the audiovisual assets and a second video-on-demand catalog comprising a second (different) group of the audiovisual assets. The application server module, the first group of CPE, and the second group of CPE are further cooperatively configured to make the first video-on-demand catalog available to the first group of subscribers and to make the second video-on-demand catalog available to the second group of subscribers.

A media player system is provided for receiving and processing a media program that uses a time interval interval t.sub.D required to decode N.sub.D frames of the media program segment. The media system receives the requested media program segment, processes the segment and determines if the throughput of the media program differs from the desired presentation throughput by a tolerance amount. Both decoding and rendering performance are determined and used to determine presentation throughput, and to determine if heavier or lighter variants of the media program should be requested for subsequent media program segments.

A channel content creation system capable of readily creating channel content is provided. A channel content creation system 1 selects program contents permitted to be published on a channel of a channel director from a plurality of program contents, extracts program contents satisfying a program search condition input by the channel director from the selected program contents, and displays the extracted program contents as candidates of program content to be selected when the channel director creates channel content. In addition, the channel content creation system 1 selects advertisement contents permitted to be published on the channel of the channel director from a plurality of advertisement contents, extracts advertisement contents satisfying an advertisement search condition input by the channel director from the selected advertisement contents, and displays the extracted advertisement contents as candidates of advertisement content to be selected when the channel director creates channel content.

A broadcast receiving apparatus includes: a digital broadcast receiver configured to receive digital broadcasting in which contents are transmitted; a network transceiver configured to execute network communication; a data string converter configured to perform a mixing process for creating a new coded data string based on a coded data string of the received contents and a coded data string acquired by the network transceiver; a digital interface configured to output the contents to external equipment; and a controller configured to determine a state of the network communication of the external equipment. The state of the network communication of the external equipment includes a first state in which the network communication is in a communicable state and a second state in which the network communication is in an uncommunicable state. In accordance with the determined state of the network communication, the digital interface performs three types of output operations.

The present invention is directed to a content creation system comprising one or more client devices, one or more servers including a database for storing information related to a plurality of items to be displayed and sold during a show, identification information associated with the plurality of items, a quantity of the plurality of items in stock in a warehouse, a plurality of audio segments, and a plurality of video segments, and a program creation unit for processing the information received from the database and for creating the show for subsequent broadcast, the show having a plurality of plays. The system also includes a network coupled to the one or more client devices and the one or more servers for allowing the one or more client devices to communicate with the one or more servers.

Systems and methods are disclosed herein for storing configuration data as a set of master data and override data where one set of configuration data is defined as the master and every other set of configuration data is defined as override configuration data. A media guidance application may generate master configuration data including the most common configuration data used in the geographical region served by the media guidance application, and number of override configurations which contain only those data which differ from the master configuration data for a number of sub-regions of the geographical region. This reduces duplicative configuration data, and the media guidance application need only store one full set of configuration data, namely the master configuration data, and a number of smaller override configurations.

Providing a coordinated primary media stream with an aggregate supplemental media stream is disclosed. A request is received from an end user device associated with a user for supplemental media. Metadata and a broadcast time associated with a primary media stream transmitted to the end user device are determined. Based on the metadata and the broadcast time, first supplemental media from a first account of the user on a first platform and second supplemental media from a second account of the user on a second platform are determined. The first supplemental media and the second supplemental media are merged into an aggregate supplemental media stream. The aggregate supplemental media stream is streamed in synchronization with the primary media stream.

Systems and methods for providing an advertisement marketplace where buyers and sellers can trade mediacast advertisement inventory programmatically at local, national, and/or worldwide levels. The marketplace system may include a seller-controlled marketplace system which connects sellers with buyers and offers revenue management tools for optimizing yields across direct and programmatic channels. The advertisement inventory is bought and sold as canonical inventory units which group similar but discrete advertisement slots together. The marketplace system may include a seller side platform (SSP) for sellers through which sellers can access demand across multiple sales channels and can make advertisement inventory available and accept or reject bids based on marketplace demand.

An apparatus for providing online multimedia contents acquires, in a pre-designated manner, a content table addresses, in which a content table consisting of a plurality of content information with each set time to be played back is stored, maps and stores the content table address to a designated channel, obtains the content table based on the content table address, analyzes the content information corresponding to the current time among the plurality of content information included in the content table to obtain a content address where a multimedia content is stored, acquires the multimedia content online based on the obtained content address, outputs the multimedia content through TV, thereby allowing a TV user to easily view various multimedia contents available online by simply changing the channel buttons of the remote control and thereby maximizing the user convenience of online multimedia contents.

An electronic apparatus maps each of a plurality of services to a channel number and provides an electronic program guide (EPG) that includes a broadcast channels and the plurality of services mapped to channel numbers of the electronic apparatus.
