Abstract: An example apparatus that processes DTVCC data has a demultiplexer that extracts DTVCC data packets from an DTV signal. A parser receives the DTVCC data packets and parses the data packets by: passing normal DTVCC data to a CC decoder; detecting ancillary data in the DTVCC data packets; and separating the ancillary data from the DTVCC data for output to an ancillary data process. An example apparatus that processes DTVCC data has an ancillary data packager that packages data ancillary to DTV data for insertion into the DTVCC data packets. A DTVCC data packager receives CC data from a CC data source into DTVCC data packets and packages the ancillary data together with the DTVCC data into DTVCC data packets. A multiplexer multiplexes the DTVCC data packets from the DTVCC data packager with non-CCDTV data to produce DTV signal data. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Abstract: A video controller selects a channel for premises broadcasting to a premises television based on a fast scan of signal strength in channels available over a premises media. The signal strength of certain filtered channel frequencies can be evaluated to determine if a channel is occupied. Unoccupied channels can be ranked in relation to nearby occupied or unoccupied channels. The nearby channels may be ranked in terms of the signal strength content in relation to the channel being evaluated. The video controller can select an unoccupied channel with an optimal ranking to permit premises broadcasting with reduced interference or conflict with other channels.

Abstract: A method and terminal for providing Internet Protocol Television (IPTV) and other communication services to a group of users, such as a family, using an IP Multimedia Subsystem (IMS) network. A group private user identity is associated with a group public user identity and with a plurality of individual public user identities, each of which is associated with a different user in the group. Utilizing the group private User ID and the group public User ID, a browser registers a group subscription with the IMS network. When an individual user enters an identifier such as a PIN, the individual is then registered with the IMS network, while maintaining the group registration with the IMS network and the IPTV network. Individual users can be changed without having to restart the browser.

Abstract: An electronic program guide system and a method for generating an electronic program guide are disclosed. A first information handling system obtains programming information from a program information source and generates a program guide based upon the obtained program information. A second information handling system receives the program from the first information handling system via downloading or transmission. The first information handling system searches a worldwide network for information regarding a transitory broadcast event and incorporates the transitory event information into the generated program guide prior to transmitting the program guide to the second information handling system. The transitory broadcast event information may be added to the program guide as additional, temporary channels that include links to the nodes from which the transitory broadcast event may be obtained. The program guide is thereby augmented with the additional, transitory broadcast event information.

Abstract: A sound processing system including at least one microphone, an audio processor, and at least one output device. The audio processor includes an analog beamformer, a microphone equalizer, and an apparent incidence processor. Two different embodiments of the apparent incidence processor are disclosed, that is, a wave generation method and a forward filtering method.

The present invention offers improved noise reduction also for environments with many independent noise sources. Furthermore, the present invention works for signals and noises with arbitrary statistics.

Abstract: Essentially all of the processing parameters which control processing of a source audio signal to produce an encoded audio signal are stored in an audio processing profile. Multiple audio processing profiles are stored in a processing profile database such that specific combinations of processing parameters can be retrieved and used at a later time. Audio processing profiles are organized according to specific delivery bandwidths such that a sound engineer can quickly and efficiently encode audio signals for each of a number of distinct delivery media. Synchronized A/B switching during playback of various encoded audio signals allows the sound engineer to detect nuances in the sound characteristics of the various encoded audio signals.

Abstract: A TSP signal that is a measurement signal is generated N times by a signal generating portion. The generated TSP signals are supplied to a steel-echo apparatus. Reverberation generated by the steel-plate echo apparatus corresponding to the TSP signals is arranged N times corresponding to the start points of the TSP signals and synchronously added by a synchronously adding portion. Generating impluse signal is convoluted by an inverse function to TSP signal. The added result of the synchronously adding portion is supplied to an impulse response converting portion. By dividing the added result by the inverse characteristics of the TSP signals, the added reverberation is converted into an impulse response. The impulse response data obtained by the converting portion is recorded to for example a CD-ROM and supplied to a reverberator. The reverberator reproduces an impulse response recorded on the CD-ROM and performs a convolution calculation process for the input signal.
