Title: Innovations of Gary W Chan
Introduction
Gary W Chan is a notable inventor based in Scarborough, Canada. He has made significant contributions to the field of communication technology, particularly in the area of data transmission and authorization systems. With a total of 2 patents, Chan's work has advanced the way information is processed and delivered in multiservice communication systems.
Latest Patents
One of Chan's latest patents is a system and method for transmitting and receiving variable length authorization information. This innovation allows for the transmission of authorization data, such as blackout and spotlight regions, across multiple sessions of data frames. By spreading this information, more space can be allocated for service provision. The authorization data is framed by START and STOP fields, enabling variable lengths, which simplifies the calculation of circular blackout and spotlight regions by transmitting a distortion factor from the encoder to the decoder.
Another significant patent by Chan is a system and method for simultaneously authorizing multiple virtual channels. In this system, a decoder receives various services as data streams, including video, audio, teletext, and utility data, which are multiplexed in a sequence of frames. Each service defines a virtual channel, and the decoder extracts virtual channel packets to provide decrypted data streams for selected channels. This process allows users to access multiple virtual channels simultaneously, enhancing the overall user experience.
