Abstract: The digital broadcast receiving apparatus according to the present invention includes: a first decoding unit which decodes video data of a first digital broadcast and outputs first video data that is decoded; a second decoding unit which decodes video data of a second digital broadcast and outputs second video data that is decoded; and a selection unit which selects one of the first video data and the second video data, and the first decoding unit outputs the first video data synchronous with a referential clock when the first video data is selected by the selection unit, and the first decoding unit outputs the first video data with timing delayed or accelerated by as much as an offset value with respect to timing of predetermined periodicity when the first video data is not selected by the selection unit.

Abstract: A service management section for managing quality information of a provided service and a received service is provided at each node so as to manage correspondence between each service and isochronous connections. When detecting a deficiency of the band at the start of a new service, each node determines a list of services whose quality can be decreased based on service information acquired from the service management sections of all the nodes on a transfer path and then decreases the quality of the service and reduces a corresponding isochronous connection band. Thereafter, band reservation is attempted again.
