20130093949 | MODE BASED FILM MODE DETECTION - In general, in one aspect, the frames of a received video are analyzed using traditional film mode detection (continually capturing data and comparing the data to known parameters for various film modes) until a film mode is detected. Once the film mode is detected, the frames of the received video are analyzed using mode based tracking where measurements are continually predicted based on the mode detected and averaged with actual measurements. The use of the averaged measurements limit the effect of noise captured in the actual measurements. The averaged measurements are continually compared to known parameters for the detected mode to determine if the detected mode is still valid. If the detected mode is valid, the mode based tacking is continued. If the detected mode is no longer valid (e.g., averaged measurements not correlated with known parameters), the process returns to the traditional film mode detection. | 04-18-2013 |
20130279888 | TECHNIQUES FOR SYNCHRONIZATION OF AUDIO AND VIDEO - Techniques are described for determining whether a stream is in a stable state and permitting adjustment of the PTS value when the stream is in a stable state. The stream can be in a stable state when PTS values received over a period of time do not change unexpectedly. For example, when the stream is in a stable state, the PTS value for audio or video can be adjusted based on system buffer levels, i.e., over flow or under flow. The amount of adjustment of the PTS value can be based on whether the buffer level appears to be moving into greater overflow or underflow. In some cases, when the stream is not in a stable state, the audio is permitted to be played back at a sample rate and video is permitted to be played back at a frame rate instead of being controlled by PTS. | 10-24-2013 |
