Abstract: Approaches for dynamically allocating CPU cycle resources to a video encoder. A resource allocator assesses an amount of available CPU cycle resources on the hardware device on which it executes. The resource allocator determines that a change in the amount of available CPU cycle resources has occurred. The resource allocator, adjusts, in real-time, which particular cycle profile, in a plurality of cycle profiles, is assigned to at least one of a plurality of video modules. The plurality of cycle profiles each allocate, to video modules, a particular amount CPU cycle resources for processing digital video. The plurality of cycle profiles also each specify a set of configuration settings and are arranged in a sequence based upon the video quality and density achievable by video modules using configuration settings associated with each cycle profile when processing digital video.

Abstract: The present invention provides method and apparatus for transmitting stereo and surround sound information of the L-R signal without excessive attenuation at the higher frequencies in order to allow transmission of surround sound through a noisy medium. The apparatus includes an audio breakout matrix (20) coupled to receive a left (12) and a right (14) audio inputs; a surround sound conditioner (22) coupled to receive a L-R signal portion of the television signal for pre-emphasizing and companding the L-R signal to produce a conditioned L-R signal; a mixer (26) coupled to the surround sound conditioner for switching the conditioned L-R signal at a predetermined value to produce an amplitude modulated L-R signal; and a synchronizing circuitry (24, 29) coupled to the mixer for maintaining the predetermined value in step with the reference value, wherein the mixed L-R signal is combined with a L+R signal portion of the television signal to produce a composite output signal (18).

Abstract: A method and apparatus for information labeling and control includes central station (10) equipment which combines a program signal with content labels which separately and continuously identify the audio, video, and data content of the program signal, and viewer station (20) equipment which generates a local content label identifying program material which is acceptable to the user. By comparing the two labels the user station equipment can block or substitute alternative audio, video, or data for offensive portions of a program signal received through a transmission or stored for playback on various media such as video tapes, audio tapes, CDs, computer disks, optical storage media, and video cartridges.

Abstract: A radio receiver receives FM subcarrier transmissions, and stores the transmitted textual information in a random access memory. The information is typically news, weather, sports, entertainment or other information of interest. A user interface allows selection from the memory of the stored information via a set of menus controlling a hierarchical database, so as to access particular items of information. A speech synthesizer accepts the accessed textual information items and transforms them into spoken speech. The user interface is either by voice or a single or multi-position switch allowing scanning through and selection from the menu items.

Abstract: A process for transmitting and/or storing digital signals from several channels is particularly suitable for transmitting the five channels of a 3/2 stereophonic system, as well as for transmitting two stereo channels and three additional commentary channels. This process allows for example television programmes to be broadcast together with multilingual audio signals. This process is characterised in that only a bit rate of 384 kbit/s is required for transmission, thanks to the reduction of the data to be transmitted. In order to reduce the data, K input channels are reproduced segment by segment on N

Abstract: In order to transmit digital data, in particular sound data, in a TV channel above the picture signal, it is proposed that the digital information is inserted as a channel-coded signal on at least one existing, frequency-modulated RF sound carrier above the TV sound channel in the base band. This lowers the modulation amplitude of the channel-coded signal with respect to the modulation amplitude of the sound signal to an extent such that interference in the receiver is excluded.
