A media server in the home entertainment network allows a media rendering devices to act as a digital media receiver. The media server enables trick mode functions such as scan forward or reverse, slow motion, pause, and seek on rendering devices with capabilities limited to 1× playback. The media server receives commands from user input at the rendering device transmitted over the network to the media server. The media server manipulates the media stream before the transmission over the network by deleting or adding frames to the media stream as necessary to emulate the desired playback functions and replacing frame timestamps to create a media stream that appears to the media rendering device as a sequential 1× stream. The transmitted media stream may not contain all of the media content stored in the corresponding media file on the media server, thus avoiding limitations on the download bandwidth and local client storage.

Vehicle event data playback systems have been devised and invented to provide authorized users means for advanced visual review. Detailed circumstances relating to vehicle operation are visually presented in these unique playback systems. In particular, a group of cooperating visual display devices operate in conjunction with each other to effect a detailed visual presentation of a vehicle's operational states. An interested party is afforded a high level of access to many data types in highly graphical and intuitive arrangements. Further, data replay access is enhanced by slow motion, fast forward, loop repeat, among others which have never before been associated with these data types nor with the compound visual presentations first taught in the accompanying disclosure.

A method and apparatus for dynamic quality adjustment based on changing streaming constraints is provided. According to one aspect of the present invention, a video stream is sent to a client according to a set of streaming constraints. At least a subset of the video information in the video stream is sent from a first source. Next, a signal is received indicating a relaxation of streaming constraints corresponding to the video stream. In one embodiment, the signal is a freeze frame signal. In another embodiment, the signal is a slow motion signal. In response to the signal, a set of improved quality video information from a second source is accessed and sent to the client. According to one embodiment, the set of improved quality video information comprises a still image. According to another embodiment, the set of improved quality video information comprises a set of preprocessed video information ready to be streamed. As a result of the techniques described herein, an improved quality visual image is available for presentation on the client and, consequently, when a viewer requests a presentation rate that reduces the streaming constraints on a video streaming service, the improved quality video information may be sent using the freed-up portion of the bandwidth previously allocated to the client.

The present application relates to tracking a position of a device, e.g. for detecting slow and rapid earth deformation, by making use of a recursive filter having the filter characteristic adapted to a detected type of motion. If the motion of the position tracking device is rapid, the filter characteristic is set such that the rapid motion can be tracked with the necessary speed. On the other hand, if the motion is slow, e.g. during times of a normal tectonic drift, the filter characteristic is set such that the motion is slowly tracked with the advantage of efficient noise reduction, i.e. noise in the input signal is effectively barred and does not pass through the filter to the output signal. Thus, in times of rapid motion the convergence speed of the filter output signal to the input signal is set high for fast convergence and in times of slow motion the convergence speed of the filter output signal to the input signal is set low for a slow convergence. The filter may be a Kalman filter.

MPEG coded video data includes groups of pictures (GOPs). Each group of pictures includes one or more I-frames and a plurality of B- or P-frames. To produce an MPEG slow-forward coded video stream, the coding type of each frame in the MPEG coded video data is identified, and freeze frames are inserted as a predefined function of the identified coding type and as a predefined function of a desired slow down factor. In a preferred implementation, for a slow-down factor of n, for each original I- or P-frame, (n−1) backward-predicted freeze frames are inserted, and for each original B-frame, (n−1) copies of the original B-frames are added, and a selected amount of padding is added to each copy of each original B-frame in order to obtain a normal play bit rate and avoid video buffer overflow or underflow.

When a video stream is edited in compressed domain to achieve video editing effects, the edited bitstream may violate the receiver buffer fullness requirement. In order to comply with the buffer fullness requirement, buffer parameters in the bitstream and the file format are adjusted to ensure that the buffer will not become underflow or overflow due to video editing. As such, re-encoding the entire bitstream is not needed. If the editing effect is a slow-motion effect, a fast motion effect or a black-and-white effect, the buffer parameter to be adjusted can be the transmission rate. If the editing effect is a black-and-white effect, a cutting effect, a merging effect or a fading effect, the compressed frame sized can be adjusted.

Slow motion is added to a video clip using retiming. Retiming adjusts the timing of the video. The video sequence may be stored ahead of time, modified in real time as the video is collected, or in real time as the video is played back. A memory stores a video sequence. A processor selects a subset of frames from the video sequence based on a focus frame identifier and a slow motion timing pattern. The processor generates at least one intermediate frame for insertion into the subset of frames based on the slow motion timing pattern for the video sequence and the focus frame identifier for the video sequence.
