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.

System for interlaced video data

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.

An optical ring network for use, for example, in a motor vehicle, includes an optical data line that defines a ring network, a playback transducer and at least one data source connected to the optical data line, where the data source provides compressed data onto the optical data line. The network also includes at least one data sink connected to the optical data line, which receives the compressed data from the optical data line. The data sink includes a bit stream decoder that decompresses the received compressed data and provides the decompressed data to the playback transducer. The local network transmits audio and video data in compressed form via the data line, and has a single bit stream decoder, centrally situated at the respective data sink, for decompressing the audio and/or video data. As a result, the individual data sources no longer need their own bit stream decoder for decompressing the data. By the assignment of such a bit stream decoder centrally to the relevant data sink, the components of the individual subscribers are distributed in a more efficient manner within the network, which better utilizes the available data transmission capacity of the network, due also to the transmission of compressed data instead of decompressed data. Overall costs of the network are also reduced.

Local video and audio network with optical data line

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.
