摘要： According to one embodiment of the invention, a method comprising an operation of identifying what programming content is currently being transmitted or is scheduled to be displayed by an electronic device that is adapted to receive programming content from a live content broadcaster. A lookup of networked content providers having stored content associated with the programming content is performed and metadata associated with the stored content is obtained. Then, relational information from the metadata is produced. The relational information is output for rendering at least one advanced option icon that is adapted to provide enhanced viewing functionality.

摘要： The disclosure discloses a live broadcast delaying method and apparatus, the method including: receiving live streaming media transmitted on the spot; segmenting the live streaming media into segmented files at a preset length of time; if a live broadcast delay instruction is received, then obtaining a delay period of time indicated by the live broadcast delay instruction; calculating a play start point of time from the current system time and the delay period of time; searching for one of the segmented files corresponding to the play start point of time, and downloading the segmented file searched to a cloud encoder; encoding the segmented file downloaded in the cloud encoder into delayed live streaming media; and transmitting the delayed live streaming media to a streaming media server, so that the live broadcast can be delayed without any additional costly delay device to thereby lower a cost of delaying the live broadcast.

摘要： A content monitor includes a processor that at least receives requests from a plurality of clients for content, instructs each client to retry their respective request at a first later time if the request is received before a first time, counts the requests to determine if a number of the requests exceeds a threshold if the request is received before a second time, instructs each client to retry their respective request at a second later time if the counted number of requests does not exceed a first threshold, instructs each client to join a multicast group to receive the content when the number of requests exceeds the first threshold, and counts a number of late clients joining the multicast group after a first portion of the content has been sent to the multicast group.

摘要： A method and apparatus for staggercasting are described including encoding and compressing a first data sequence, packetizing the compressed encoded data sequence to form a data packet, performing forward error correction (FEC) encoding on the data packet in order to generate a second data sequence related to the first data sequence, appending FEC control information as padding to the end of payload data of the data packet, packetizing the second data sequence to form a packet, multicasting the data packet to a first multicast group, multicasting the packet formed using the second data sequence delayed by an offset time to a second multicast group.
