Abstract: A method of bitstream verifying includes at the encoder side, the coded picture data of a spliced bitstream, containing a library bitstream and a main bitstream, is processed by different operations in the hypothetical bitstream buffer to simulate the data fulfillment level of the bitstream buffer. This is used to check whether the hypothetical bitstream buffer is overflowed or underflowed and verify the qualification of the bitstream. A method of managing bitstream at the decoder side is exploited to decode the library picture, which is inserted in the spliced bitstream, at a proper time. This ensures that a bitstream buffer with a limited capacity neither overflows nor underflows and the decoder can decode and present the picture of the main bitstream at a proper temporal order, which avoids lag of the main bitstream picture and waste of the decoded picture buffer.

The video decoding resource is then re-allocated to another input buffer to provide an input data stream of an other application to the video decoder to generate the output data stream. The input buffer of the input data streams associated with the application prior to receiving the event is maintained in a suspended state while the respective application is still active but is not associated with the video decoder.

Abstract: A digital video recorder stores digital video streams having sequences of encoded frames that are predominantly non-keyframes. The digital video recorder synthesizes keyframes for the digital video stream by decoding the frames in sequence and occasionally capturing the state of the decoder as it decodes the frames. The decoder states are stored in a state index in association with the frames. During playback at normal or accelerated speeds, the digital video recorder is capable of random accelerated access of any frame in the digital video stream. A decoder state associated with the accessed frame is retrieved from the state index and used to begin decoding at or near the accessed frame. The decoder state initializes a playback decoder to the state that enables complete decoding and rendering of the accessed frame without having to decode multiple frames previous to the accessed frame, thereby minimizing time delays in playback.

Abstract: Trick mode playback is implemented by disengaging a frame synchronization signal, and then decoding “I” and “P” frames to two (or more) buffers. Specifically, each buffer has a pointer that is associated with a memory/origin address. The pointers are locked in place by disengaging the frame synchronization signal. Once the pointers are locked in place, the “I” frames and “P” frames are decoded to the two buffers in an alternating fashion based on a continuous swapping of the memory addresses associated with the two pointers. Because both “I” and “P” frames (as opposed to only “I” frames) are decoded and displayed, the trick mode playback appears smoother. In addition, because the frame synchronization signal was disengaged, the frames can be decoded at a rate faster than a single frame time. That is, one frame need not be completely decoded and read out before the next frame is decoded.

Abstract: A new approach is proposed that contemplates systems and methods to support video-aware screen capture and compression. More specifically, the video-aware approach first detects whether or when video content is being actively played back on a screen of a hosting device. If the video content is actively being rendered, the approach separates (segments) the screen content into static (non-video) content and video content, The approach then applies video-specific capture and compression methods to the video content of the screen and other suitable compression methods to the non-video content of the screen. The compressed static and video content of the screen are separately and independently transmitted across the network to remote computing devices and are then decompressed and processed to reconstruct screen of its original content for display at the screens of the remote computing devices.
