A computerized system including a memory and a computer processor may arrange a plurality of video frames based on one or more data items associated with groups of pictures (GOPs) and/or video playing commands and/or settings, and render and/or play the arranged frames on an output display. Functionalities enabled by different embodiments of the invention include, for example: automatically adjusting a video playing speed according to a number of accumulated frames within a memory buffer; appending a memory buffer with frames included in another (e.g., separate) memory buffer based on a requested video playing direction; omitting frames from a video sequence (thus sparing the need to process omitted frames) based on quantifying their information content and/or distance from reference frames; and synchronizing video playing on different (e.g., remote) computer systems. ## Claims ### Claim 1 A method for intelligent video playing, the method comprising: in a computerized system comprising a memory and a computer processor: arranging, by the processor, a plurality of video frames based on one or more data items, the data items associated with one or more groups of pictures (GOPs) and one or more video playing settings, wherein one or more of the frames are included in a first memory buffer, and wherein the arranging comprises appending, by the processor, a second memory buffer with one or more of the frames included in the first memory buffer, the appending based on a requested video playing direction; and rendering and playing, by the processor, the arranged video frames on an output display. ### Claim 2 (depends on 1) The method of claim 1, comprising automatically adjusting, by the processor, a playing speed based on a video acceleration database, the database associating a plurality of playing rates to numbers of accumulated frames within one or more memory buffers; and wherein the playing of the arranged video frames is performed based on the adjusted playing speed. ### Claim 3 (depends on 1) The method of claim 1, wherein the arranging comprises omitting, by the processor, one or more of the frames; and wherein the rendering and playing do not include the omitted frames. ### Claim 4 (depends on 3) The method of claim 3, comprising calculating, by the processor, a frame drop factor, the factor determining, for a given playing speed, a number of frames to be omitted; and wherein the omitting of one or more of the frames is performed based on the frame drop factor. ### Claim 5 (depends on 3) The method of claim 3, comprising: for one or more of the frames, calculating, by the processor, an information score, the information score quantifying an amount information lost if a given frame is omitted from a set of frames; and wherein the omitting of one or more of the frames is performed based on the information scores. ### Claim 6 (depends on 5) The method of claim 5, wherein the information score comprises a frame size, and wherein the method comprises normalizing, by the processor, each of the information scores. ### Claim 7 (depends on 5) The method of claim 5, comprising: calculating, by the processor, a dispersion score for one or more of the frames, the dispersion score measuring a distribution of one or more of the frames within a time interval; wherein the omitting of one or more of the frames is performed based on the information scores and based on the dispersion scores. ### Claim 8 (depends on 7) The method of claim 7, wherein the dispersion score includes a distance between one or more of the frames and a reference frame; and wherein the omitting of one or more of the frames is performed for a first time interval, and wherein the reference frame is in a second time interval. ### Claim 9 (depends on 2) The method of claim 2, wherein the adjusting of a playing speed is performed based on a reference video playing of a remote computer. ### Claim 10 A computerized system for intelligent video playing, the system comprising: a memory, and a computer processor configured to: arrange a plurality of video frames based on one or more data items, the data items associated with one or more groups of pictures (GOPs) and one or more video playing settings, wherein one or more of the frames are included in a first memory buffer, and wherein the arranging comprises appending a second memory buffer with one or more of the frames included in the first memory buffer, the appending based on a requested video playing direction; and render and play the arranged video frames on an output display. ### Claim 11 (depends on 10) The computerized system of claim 10, wherein the processor is to: adjust a playing speed based on a video acceleration database, the database associating a plurality of playing rates to numbers of accumulated frames within one or more memory buffers; and wherein the playing of the arranged video frames is performed based on the adjusted playing speed. ### Claim 12 (depends on 10) The computerized system of claim 10, wherein the arranging comprises omitting one or more of the frames; and wherein the rendering and playing do not include the omitted frames. ### Claim 13 (depends on 12) The computerized system of claim 12, wherein the processor is to: calculate a frame drop factor, the factor determining, for a given playing speed, a number of frames to be omitted; and wherein the omitting of one or more of the frames is performed based on the frame drop factor. ### Claim 14 (depends on 12) The computerized system of claim 12, wherein the processor is to: for one or more of the frames, calculate an information score, the information score quantifying an amount information lost if a given frame is omitted from a set of frames; and wherein the omitting of one or more of the frames is performed based on the information scores. ### Claim 15 (depends on 14) The computerized system of claim 14, wherein the information score comprises a frame size, and wherein the method comprises normalizing, by the processor, each of the information scores. ### Claim 16 (depends on 14) The computerized system of claim 14, wherein the processor is to: calculate a dispersion score for one or more of the frames, the dispersion score measuring a distribution of one or more of the frames within a time interval; and wherein the omitting of one or more of the frames is performed based on the information scores and based on the dispersion scores. ### Claim 17 (depends on 16) The computerized system of claim 16, wherein the dispersion score includes a distance between one or more of the frames and a reference frame; and wherein the omitting of one or more of the frames is performed for a first time interval, and wherein the reference frame is in a second time interval. ### Claim 18 (depends on 11) The computerized system of claim 11, wherein the adjusting of a playing speed is performed based on a reference video playing of a remote computer.
