Abstract
The present disclosure relates to devices and methods for switched digital video (SDV) systems. A first device used in an SDV system is provided, which can perform the following operations: generating a list of opened channels, wherein the list of opened channels includes at least one data field associated with one or more channels, each data field including a channel identifier and an encoding format identifier, wherein the channel identifier identifies a channel, and the encoding format identifier identifies the encoding format of one of data streams of one or more encoding formats for the channel identified by the channel identifier; and sending the list of opened channels to a second device, so that for each data field, the encoding format corresponding to the encoding format identifier of the data field is compared with the decoding capability of the second device, and the data field is retained in response to the encoding format matching the decoding capability, while the data field is discarded in response to the encoding format not matching the decoding capability.
