摘要:
A system is presented for the multipath reception of video signals, including sound an/or image signals. The system includes at least two receivers and a diversity unit. At least one receiver receives and processes analog video signals, while the one or more remaining receivers receive and process digital video signals. The system may further include an analog selector unit for selecting the highest quality analog signal, and/or a digital selector unit for selecting the highest quality digital signal. The diversity unit receives the processed analog and digital video signals and combines them to produce a resulting video signal having a quality at least as high as the better of the processed analog and digital video signals. The diversity unit may combine the received video signals by performing a weighted addition of the signals.

A reproduction system reproduces interlaced video data in a deinterlaced form. The system selects a deinterlacing algorithm used to process the interlaced video data. The deinterlaced video data is sent to a display device. The reproduction system responds to a manual or automated input that selects a deinterlacing algorithm.

A vehicle-hosted local network includes a subscriber data source that transmits audio data and compressed video data to respective subscriber data sinks on the network. The subscriber data source includes a demultiplexer that separates compressed audio data and compressed video data contained in one compressed source signal. A pre-processing circuit processes in parallel the separated audio data and the separated video data to provide the audio data and the compressed video data that is transmitted to the respective subscriber data sinks on the network.

A digital television system includes a network that connects a display, an operating unit that requests a program or program information, and a television reception unit, a demultiplexer that separates the audio, video and miscellaneous data, a matching stage that matches the audio signal with the video signal, a multiplexer that combines the audio and video signal into one data stream, an evaluation device in communication with the demultiplexer, a memory that stores the miscellaneous data and a controller that manages the miscellaneous data. The memory and the controller form a server unit, and the controller is in communication with the operating unit. The miscellaneous data is transmitted to the network by the controller when recalled from the memory.

A vehicle entertainment and information processing (VEIP) system may allow a user to listen to quality broadcast signals while moving through regions of varying signal strength. The VEIP system includes a navigation unit, a tuning receiver, and a system controller to analyze broadcast signals based on a broadcast station database. The VEIP system may switch to alternate broadcast stations when the broadcast signal degrades because of terrain, position of the vehicle, or other driving conditions.

The invention relates to the reproduction of a television signal on a distant reproduction device. The received television signal is encoded and transmitted in a digital data format over a communication link to the reproduction device. The reproduction device decodes the received video information for display on a display screen. The invention is particularly intended for use in mobile vehicles, coaches and trains, where the signal strength of a received television signal during travel is continuously varying and signal distortions occur frequently. In order to reduce the effect of signal distortions on the perceived image and audio quality, the invention inserts a compressed pre-stored video or audio data into the data stream transmitted from the television receiver to the reproduction device upon detection of a television signal distortion. Thus, the decoding procedure at the display device can be maintained in spite of a received television signal of insufficient signal strength.

A bit-stream converter capable of converting a first synchronous compressed bit-stream of data at a first sampling rate to second synchronous compressed bit-stream frame of data at a second sampling rate is disclosed. The bit-stream converter architecture may include a payload length detector and a zero stuffing unit in signal communication with the payload length detector. The zero stuffing unit is capable of zero stuffing section responsive to the payload length detector detecting the payload length.
