摘要:
An interactive television program guide is provided. The interactive television program guide provides a user with the opportunity to select a language for playing television programming and displaying program guide text. Television program audio in the desired language may be obtained from a SAP or digital audio track and played in the selected language. Television related information in the desired language may be obtained from a digital track. If television program audio or related information is not provided in the selected language, the program guide may use a default language. The program guide may coordinate program guide display screen text with languages available for television programs when the programs are broadcast to users.
摘要:
Encoding parameters of picture and higher layers of importance to a number of applications, and encoding parameters of slice and lower layers of no importance to all applications are converted into auxiliary packets inserted respectively into a V-blanking area and an H-blanking area of a video-data signal output by a history-information-multiplexing apparatus employed in a video-decoding system. On the other hand, a video-encoding system extracts back the auxiliary packets superposed on the V-blanking area and the H-blanking area from an input base-band video signal. As a result, a technique of superposing information on data can be changed in accordance with the importance of the information and required information can be fetched with ease.

A media recording system may be provided. The recording system may include features for reducing recording cut-off of a particular media event due to changes in the start time and end time of what is scheduled to be recorded. The recording system may provide a user with an opportunity to select a program by for example, selecting a listing, to have that program automatically recorded at a scheduled time for presentation to viewers. Changes in the schedule of programs may be compensated manually or automatically when the recording system receives information about actual or predicted time changes. In a manual mode, a user may adjust start or end times based on time change information that is displayed. For an automatic mode, the recording system may automatically compensate for predicted or actual time changes that are known by automatically adjusting the start and end times of recording.
摘要:
In an electronic endoscope system (2), an RF signal is produced through quadrature modulation of a picture signal that is representative of an image taken through an electronic endoscope (10). When control signals are entered by an operator through a control section (14) of the electronic endoscope, a data superimposing section (35) superimposes the entered control signals (Da, Db, Dc) on the RF signal in horizontal scanning intervals (Th) within a vertical blanking interval (Tb1). The RF signal having the control signals superimposed thereon is sent as an electric wave of a single frequency band to a processor (11). In the processor, a data analyzer (69) carries out sampling to extract the entered control signals if they are superimposed on the picture signal, and analyzes the contents of the entered control signals. Based on the results of analysis, a CPU (60) controls respective components of the signal processor.

摘要:
A broadcast receiver and a method for processing a digital caption using the same. A broadcast receiver receives a broadcast signal containing digital caption information, searches for an explanation of terminology to be explained if terminology in the digital caption information is included in a list of terminology to be explained, and displays the explanation found for the terminology to be explained on a screen.
摘要:
A system is described for distributing TV signals to an end-terminal. The system comprises at least one central broadcast station, a channel manager and one or more end-terminals connected to the channel manager. The broadcast station is adapted to transmit at least one TV channel signal, comprising an audio signal and a video signal and one or more service signals to the channel manager. Further, the channel manager is adapted to receive the TV channel signal, to extract the audio, video and service signals from the TV channel signal, to transform the signals into packetized elementary streams and to transmit a packetized data transport stream to the channel manager. The transport stream comprises a TV channel stream, comprising elementary audio and video streams, and a services channel stream, comprising one or more elementary service streams and the one or more end-terminals are adapted to select between the TV channel stream and the services channel stream.
摘要:
Method and apparatus for scrambling a high definition television signal to discourage unauthorized recording of same. While recording per se is not prevented, the resulting recorded signal is rendered unusable due to an induced 'wobble' between the active video and the associated sync pulses. The scrambled television signal is readily viewable on a compliant high definition television set which descrambles the HDTV signal using an encoded indication of the amount of wobble accompanying the HDTV signal. Also provided is a special interface to prevent unauthorized persons from using the indication of the amount of wobble so as to defeat the scrambling. Also provided are method and apparatus for defeating the scrambling method and hence allowing recording of the scrambled video signal.
