The image capturing module is used for capturing a scene of an area to be displayed and outputting image data. The image processor converts the image data according to a first and a second cutting areas and a first and a second shrink ratio values, and outputs a first and a second sub-images. The first cutting area includes the second cutting area, and the first shrink ratio value is greater than the second shrink ratio value. The image encoder encodes the first and the second sub-images according to first and second encoding information, and outputs a first and a second streaming images. The network transmission module is used for transmitting the first and the second streaming images. | 2011-06-09 |
| 20110134994 | REAL-TIME TRANSPORT PROTOCOL (RTP) PACKETIZATION METHOD FOR FAST CHANNEL CHANGE APPLICATIONS USING SCALABLE VIDEO CODING (SVC) - An apparatus encodes a video signal for providing a scalable video coded (SVC) signal comprising a base layer video coded signal and an enhancement layer video coded signal, wherein the base layer video coded signal has more random access points, e.g., Instantaneous Decoder Refresh (IDR) slices, than the enhancement layer and in those access units where the enhancement layer has an IDR slice, the base layer has a non-IDR slice. Transmission of the SVC occurs in packet form using the Real-time Transport Protocol (RTP) such that non-random access point slices are conveyed in Simple Time Aggregation Packets (STAP), each Simple Time Aggregation Packet comprising a Payload Content Scalability Information (PACSI) Network Abstraction Layer (NAL) Unit. | 2011-06-09 |
