Encoder-assisted adaptive video frame interpolation

12/25/14 - 20140376637 - The disclosure is directed to techniques for encoder-assisted adaptive interpolation of video frames. According to the disclosed techniques, an encoder generates information to assist a decoder in interpolation of a skipped video frame, i.e., an S frame. The information permits the decoder to reduce visual artifacts in the interpolated frame
Inventors: Gokce Dane, Khaled Helmi El-maleh, Yen-chi Lee

Picture-in-picture processing for video telephony

02/07/13 - 20130033564 - The disclosure is directed to techniques for picture-in-picture (PIP) processing for video telephony (VT). According to the disclosed techniques, a local video communication device transmits PIP information to a remote video communication device. Using the PIP information, the remote video communication device applies preferential encoding to non-PIP regions of video
Inventors: Yen-chi Lee, Khaled Helmi El-maleh, Ming-chang Tsai

Locating motion vectors for video data units

04/01/10 - 20100080296 - An apparatus performs efficient coding techniques to more efficiently locate motion vector data within neighboring video data units. The apparatus comprises a motion vector (MV) location unit that includes a look-up table (LUT), where the MV location unit obtains video data defining a plurality of video data units and processes
Inventors: Yen-chi Lee, Yiliang Bao

Determining availability of video data units

04/01/10 - 20100080285 - An apparatus performs efficient coding techniques to more efficiently determine an availability of neighboring video data units determined for the current video data unit. The apparatus comprises an availability determination unit that maintains an availability counter. The availability determination unit determination unit increments the availability counter after each of the
Inventors: Yen-chi Lee, Kai Wang

Resolving geometric relationships among video data units

04/01/10 - 20100080284 - An apparatus performs efficient coding techniques to more efficiently resolve geometric relationships between video data units and thereby determine neighboring video data units for a current video data unit. The apparatus comprises a geometric resolution unit that obtains video data defining a plurality of video data units, and determines, for
Inventors: Yen-chi Lee, Yiliang Bao

Video decoder error handling

08/27/09 - 20090213938 - A video decoder performs a sequential error handling process to detect and conceal errors within a corrupted data segment of video data units. The decoder sequentially decodes a current data unit. Upon detecting an error, the decoder sets an error flag and resynchronizes decoding at the start of the next
Inventors: Yen-chi Lee, Min Dai, Chia-yuan Teng

Video rate adaptation to reverse link conditions

02/05/09 - 20090034610 - The disclosure relates to video rate adaptation techniques that may use information from a medium access control (MAC) layer and radio link protocol (RLP) layer. The techniques may greatly reduce video delay by adjusting video encoding rate. For real-time video telephony (VT) applications, these techniques may provide graceful quality degradation
Inventors: Yen-chi Lee, Christopher Gerard Lott, Peerapol Tinnakornsrisuphap, Vikram Gupta
