Nowadays, some powerful client devices, e.g., smart phone, set top boxes and digital video recorders, are commonly used to enhance digital TV broadcasting services. This paper proposes a virtual channel platform by organizing these client devices to virtually support each user a dedicated channel according to her/his demand. In the proposed platform, each video is partitioned into many small segments before it is shared in a peer-to-peer network. A virtual channel is constructed by composing these video segments into a long video playout sequence. However, retrieving these small segments from a large scale peer-to-peer network could cause relatively large query overhead. To reduce the number of queries, we propose a virtual stream mechanism by aggregating popular adjacent video segments to logically form a long video object. The simulation results demonstrate that the proposed virtual channel platform can improve the service performance.
