A processor-readable medium having embodied therein processor readably instructions for implementing a method for optimizing quality of streaming data transmitted between a first node and a second node over a network is also disclosed.

Abstract: A television receiver including: a reception control unit which judges whether reception of the cable television broadcast signal has succeeded, by setting the channel data composed of the combination of the frequency table stored in the first storage unit and the modulation method stored in the second storage unit, the modulation method corresponding to the tuned channel. The reception control unit sequentially changes the channel data to be set in a previously determined order to make the reception unit receive the cable television broadcast signal corresponding to the tuned channel when the reception control unit judges that the reception of the cable television broadcast signal has not succeeded.

Abstract: A delivery control central device installed in a lead car of a train delivers video information including moving image information and still image information to a delivery control terminal device of each subsequent car via an inter-car transmission path. The video information is delivered based on video content and a content display schedule that are both wirelessly received from a ground station through a transceiver device. The delivery control terminal device of each car is sequentially connected to the delivery control terminal device of an adjacent car, sequentially delivers the delivered video information to the adjacent car, and delivers the delivered video information to a video output device via an in-car transmission path inside its own car. A video output device generates video signals from the delivered video information, outputs the video signals to a display device, and displays the video signals by the display device.
