Abstract: Real-time metadata about a plurality of video streams, and information associated with a directed stream, is received. The information includes a plurality of time segments, where time segments correspond to a respective video stream selected by a director for display in the directed stream during the time segment. Additionally, it is determined, based on the information, that the directed stream will display a first video stream during a first time segment. Further, a subsidiary stream is generated for a first group of users. This involves determining to substitute a second video stream for the first video stream during the first time segment, based on real-time metadata and further based on a first set of rules associated with the first group of users. When the first time segment begins, the second video stream is outputted for display in the subsidiary stream.

Abstract: TV low cost remote control system using a microprocessor decoder. Control data is transmitted in digitally encoded form and comprises blocks of eight bits of data separated by gaps in transmission of equivalent length. Each data block consists of a start bit followed by seven bits of data for channel identification. Data is presented to the microprocessor on one input line which it samples regularly as a part of its main keyboard scan routine and in response to a start bit checks the data bits and gaps to determine presence of a valid command. The remote control information is decoded directly by the microprocessor. Using seven identification bits, a channel capacity of 128 channels is possible.
