摘要： Systems and methods are provided in which video information streams are encoded and transmitted with optimal utilization of constrained bit-rate channel. In accordance with one embodiment, among others, a system is provided, which includes synchronous multi-channel encoder (SMEs), a system multiplex controller (SMC), switches, and a multiplexer. In combination, these components receive an input video signal, and produce encoded video bit streams from the received input video signal. Each encoded video bit stream is substantially identical to other encoded video bit streams, but each encoded video bit stream has a different bit rate than the other encoded video bit streams. An optimal encoded video bit stream is determined from the encoded video bit streams. That optimal encoded video bit stream is selected, multiplexed, and than delivered to the output.

摘要： Among a first and second video data each being variable length coded data such that an occupancy of a decoder buffer is neither overflown nor underflown, having an end code at a rear end thereof and being comprised of a plurality of compressed portion data, a value related to a buffer occupancy at a decoding timing of the last picture of the first video data is compared by an invalid data amount calculator 13 with the buffer occupancy at the decoding timing of the first picture of the second video data. According to a data amount corresponding to a difference between the occupancies when the result of comparison is a predetermined one, the invalid data of this data amount is added by an invalid data adder 14 to the last picture of the first video data and the second video data is connected by a video data connector 15 to the first video data.

摘要： A method and arrangement are disclosed for transmitting television programs via a plurality of channels, and an additional data service, for example, an Electronic Program Guide, via a selected television channel. While processing and displaying the program guide, prior art television receivers cannot continue the reproduction of a currently received TV program because the program is generally transmitted via a different channel. The invention provides a solution to this problem by duplicating a signal component representing, for example, the audio contents of the various television programs in said selected television channel. This allows customers to keep up with the service they were watching before, and to immediately return to the program if something of interest appears to happen. The invention is particularly applicable in Digital Video Broadcast (DVB) systems where each channel can accommodate a plurality of TV programs.

摘要： Apparatus for asynchronously generating control signals (CONTROL) is disclosed including a plurality of sources (5) of asynchronous data signals and a plurality of data processing channels (10, 14), each processing one of the data signals in response to a control signal (CONTROL). Each of a plurality of parameter determining circuits (10, 16) produces a signal (COMPLEXITY) representing a parameter of one of the data signals. A data sampler (30) samples the signals (COMPLEXITY) from all of parameter determining circuits (10, 16) substantially simultaneously at predetermined sampling time intervals. A control signal generator (30) generates control signals (CONTROL) for the data processing channels (10, 14) having values based on the sampled parameter representative signals (COMPLEXITY) and the preceding sampling time interval.

摘要： MPEG2-based transmission systems transmit a large number of digital television programs in a single physical channel. Disclosed herein is a "Channel Navigation System" which allows a user to get an overview of the digital programs provided, and to easily select a desired program. The method of the invention includes the transmission (in a separate program of a transport stream) of a video stream representing a mosaic picture, the sub-pictures of which are miniature versions of the video stream of other programs in that transport stream. The method further includes the transmission of information which links the position of each sub-picture within the mosaic picture with the program number from which the sub-picture is derived. The user selects a desired program by merely `pointing and clicking` its miniature version in the mosaic picture.

摘要： Video receiving method and apparatus, are responsive to requests from a selector unit (240), for identifying channels (1 through n), in a transmitter system (204), containing video signals to be sent from the transmitter system (204) to one or more receiver systems (202). The receiving method includes steps of having the receiver system (202) select (94) one or more channels. The receiver system generates (90) signals identificative of the selected channels, and sends (29) the channel identifying signals to the transmitter system (204). The transmitter system uses the channel identifying signals to selectively identify the channels to be transmitted to the receiver system (202). The transmitter system compresses (17, 19, 21) and multiplexes (25) the signals of the channels selected by the receiver system (202). The receiver system (202) receives (75) the compressed and multiplexed signals, and stores (35, 37, 39) the received signals.

摘要： An implementation, as described herein, facilitates fast start-up of a new media stream while avoiding temporal interruption (i.e. “hiccups”) of the presentation of that new media stream. At least one implementation, described herein, coordinates the delivery of multiple simultaneous media streams on a media-stream network. Its coordination accounts for traversal of bandwidth-restricted chokepoints; quickly stopping delivery of one or more media streams from the set of streams; quickly initiating delivery and presentation of one or more new media streams not previously in the set (i.e., a “channel change”) and producing clean playback of all of the streams in the set, despite their different timelines. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

摘要： A method of encoding a local time base embedded in the compressed data is disclosed. The local time base is encoded in two parts. The first part has a modulo time base that indicates the specific interval in the reference time base and the second part has a time base increment relative to the reference time. Two forms of time base increment is used to allow for the possibility of different encoding order and displaying order. A mechanism for the synchronization of multiple compressed streams with local time base is also described. A time base offset mechanism is also used to allow finer granularity synchronization of the multiple compressed streams.

摘要： A device and a method for multiplexing a plurality of bit streams, a device and a method for decoding a multiplexed signal and a recording medium storing a program for multiplexing a plurality of bit streams are adapted to carry out a dividing step for dividing said second bit stream into predetermined units, an adding step for adding a start code to each of said units obtained by dividing said second bit stream and a multiplexing step for defining a user operable region in said first bit stream and multiplexing and recording at least part of said second bit stream on said user operable region. As a result, a picture signal can be decoded with minimal processing steps because a conventional coding system can be used without modification.
