Mechanisms for performing decoding of context-adaptive binary arithmetic coding (CABAC) encoded data. The mechanisms receive, in a first single instruction multiple data (SIMD) vector register of the data processing system, CABAC encoded data of a bit stream. The CABAC encoded data includes a value to be decoded and bit stream state information. The mechanisms receive, in a second SIMD vector register of the data processing system, CABAC decoder context information. The mechanisms process the value, the bit stream state information, and the CABAC decoder context information in a non-recursive manner to generate a decoded value, updated bit stream state information, and updated CABAC decoder context information. The mechanisms store, in a third SIMD vector register, a result vector that combines the decoded value, updated bit stream state information, and updated CABAC decoder context information. The mechanisms use the decoded value to generate a video output on the data processing system.

A solution for server-side rendering includes, at a server configured to store a video images representing states of users in a computer application, identifying future user actions based at least in part on a state of a user in the computer application. The solution also includes, responsive to the identifying, rendering video images for sending to a user device associated with the user. At the user device, a state of the user in a computer application is sent to the server. Responsive to the sending, video images are stored, each of the video images representing a future state of the user after the user performs a future action. Responsive to a user action, one of the video images is selected for display on a user display of the user device. According to one aspect, the future user actions identified by the server are limited to less than a possible number of user actions for users having the state.

Server-side rendering

A flexible software-based decoding system with decoupled decoding timing and output timing. In one embodiment, a computer software implemented method of decoding a data stream comprising encoded video data is provided. In this embodiment, the software method comprises the step of maintaining a number of already decoded and ready-for-output frames in a frame buffer. The method also comprises the step of decoding a first encoded frame of the data stream to generate an additional decoded frame. The method further comprises the step of outputting a first of the decoded frames before decoding of the first encoded frame is completed if the decoding step requires more time than a predefined frame output time to complete. Moreover, in this embodiment, the method comprises the step of adding the first additional decoded frame to the frame buffer. In this embodiment, real-time output is maintained irrespective of whether completion of the decoding step requires more time than the predefined frame output time for particular frames. In one embodiment, the method further comprises the step of decoding a second encoded frame of the data stream substantially immediately upon completion of the decoding step to generate a second additional decoded frame, provided that the completion of the decoding step requires more time than the predefined frame output time, and also the step of adding the second additional decoded frame to the frame buffer.

In the method and apparatus of the present invention, an editing system and method is provides that is sophisticated in features but easy to use. In one embodiment, the system includes multiple input sources, such as tape and live sources, at least one output recording device, at least one monitor, and a editing controller, such as a general purpose computer, which controls the input and output device. The controller further provides an innovative graphical user interface that intersperses video from the input devices along with control functions which the user can select using a mouse, keyboard or other input device.

Method and apparatus for displaying in and out points during video

A system for simultaneous display of multiple video windows on a display device. This system includes a primary interface for receiving a primary video signal and a primary storage memory for storing data representing the primary video signal. Further, the present invention provides a plurality of secondary interface for receiving a plurality of secondary video signals and a secondary storage memory for storing data representing the plurality of secondary video signals. An output for selectively outputting the contents of a primary storage memory and the secondary storage memory to a display device so as to display video imagery represented by the primary video signal and secondary video signals in respective multiple video windows on the display device.

System for simultaneous display of multiple video windows on a display

A one pass adaptive bit rate control method. Data from a previous video field is used to calculate a quantizer scale factor for use in compressing a current video field. Large changes in compressed data size is used to detect scene changes. When a scene change is detected, a marker is inserted into the compressed data stream in place of the compressed field. An interpolated field is substituted during decompression for the scene change marker.

One-pass adaptive bit rate control

An apparatus, including a lookup table memory, for gamma correcting a digital video signal based on the assumption that for small gamma, gamma correction is a linear function so that for a digital video input signal value x a gamma correction value d to be added to x can be calculated as a function of an opertor selected variable a according to the formulae:
