The amendment filed on 4/1/2026 has been entered and considered by the examiner.
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 1-14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Dimitrov (PGPUB 2019/0164518 A1) in view of Song (PGPUB 2013/0187832 A1).
As to claim 1, Dimitrov (Figs. 1A, 1B, 2C, 2D) teaches, a system (system 100), comprising:
a server computer (server 102)(Fig. 1A) comprising a server synchronization frame rate generator (frame timer 120, feedback adaptive frame rate controller 122 and GPU 112)(¶ 46);
a user device (client 104) communicatively connected to the server computer (jitter absorption parameter 140, user interactive inputs 142, frame arrival feedback 144, image frame stream 146, network/communication connection 106)(Fig. 1A), the user device comprising a user device synchronization frame rate generator (frame arrival monitoring 142, ¶ 47, 50) that is time synced with the server synchronization frame rate generator (¶ 46, 52, 54: i.e. frame timer 120 and feedback adaptive frame rate controller are synchronized to the remote client device display VSYNC signal 152);
wherein the user device sends the server computer an event signal (“frame late-speed up” signal, ¶ 59) at a precise time (i.e. in response to the timing of frame C being late to expected time 154) of a signal of the user device, together with a delay (increment or decrement) (duration)(¶ 102: i.e. client device operates jitter absorption parameter, JAP, and includes information regarding whether frame arrived early or late and optionally by what duration);
wherein the server computer processes the event signal and the delay, and the server computer returns a processed data to the user device (¶ 102, 110, 112: i.e. statistics are received via feedback, and FPS is newly computed to transmit frame in time),
wherein the processed data arrives at the user device at a correct time (expected arrival time 158) in sync with timing of the user device synchronization frame rate generator (¶ 66: i.e. frames E-I are sped up and transmitted at faster rate to present frames at expected arrival time 158, and ¶ 122: i.e. frame time 120 can be changed to generate and transmit frames at expected arrival time).
Dimitrov does not specifically teach, wherein the delay is computed by the user device based on a timing of the user device synchronizing frame generator.
Song (Figs. 2, 3) teaches, wherein the delay is computed by the user device (display apparatus 100-1) based on a timing (¶ 46: i.e. sync information received by interface 110 from the host device 200) of the user device synchronizing frame generator (¶ 58: i.e. control unit 130 produces information regarding the delayed time and calculate the amount of delay).
It would have been obvious to a person of ordinary skilled in the art before the effective filing date of the claimed invention to incorporate Song’s synchronizing method between the display device and the host device into Dimitrov’s display, so as to provide adjusted sync information to each of a plurality of display apparatus being used in conjunction with the tiled display system (¶ 15).
As to claim 2, Dimitrov (Figs. 1A, 1B) teaches, wherein the user device accesses processed data at the correct time (¶ 66: i.e. receive frames at expected arrival time)
As to claim 3, Dimitrov (Fig. 1A) teaches, wherein the user device includes a processor (CPU 130, GPU 132), memory (frame buffer 134, memory 136, and jitter buffer 138)(Fig. 1A).
As to claim 4, Dimitrov (Fig. 1A) teaches, wherein the server computer includes a processor (CPU 110, GPU 112) and memory (memory 116, frame buffer 114).
As to claim 5, Dimitrov (Figs. 1A, 1B) teaches, wherein the server synchronizing frame rate generator is frequency locked to the user device synchronizing frame rate generator (¶ 54: i.e. frame timer 120 is configured to fire at 60 fps to match the client device display 108 refresh rate).
As to claim 6, Dimitrov (Fig. 1B) teaches, wherein the user device sends the event signal (“frame early-slow down”) at a time delay (increment or decrement) (duration) from timing (i.e. time point 158) of the user device synchronizing frame rate generator (¶ 102: i.e. JAP transmits the feedback information, including the duration)
As to claim 7, Dimitrov (Fig. 1B) teaches, wherein the time delay enables the processed data from the server computer to arrive at the user device at the correct time (i.e. allows next expected frame to arrive on time, which is displayed as “I” in display 108) of the user device synchronizing frame rate generator (¶ 112: i.e. frame rate may be changed, which allows frames to arrive before expected arrival time 158 as shown with frames E-I in Fig. 1B).
As to claim 8, Dimitrov (Figs. 1A, 1B, 2C, 2D) teaches, a method of operations of a display-server computing system (system 100), comprising:
delivering, by a display device (display 108) to a server computer (server 102) over a communications network (user interactive inputs 142, frame arrival feedback 144, image frame stream 146, network/communication connection 106), a first signal (frame arrival feedback 144) according to a delay (increment or decrement) (frame arrival monitoring 142, which indicates duration of delay, ¶ 102) of the display device (Figs. 1A, 1B), the delay corresponds to a timing of the display device (refresh rate of the client display, ¶ 201);
processing, by the server computer, the first signal with the input (input device 109) and timing of the delay (¶ 102, 110, 112: i.e. statistics are received via feedback, and FPS is newly computed to transmit frame in time according to speed up/ slow down required),
outputting, by the server computer, a result of the processing (¶ 102, 110, 112: i.e. FPS is newly computed to transmit frame in time, and the frames are transmitted),
delivering, by the server computer to the display device over the communication network, the result of processing (¶ 50: i.e. frame images 146 are streamed at a frame rate that is adapted in accordance with the feedback 144 received);
outputting, by the display device, the result at a correct timing of the display device (¶ 56: i.e. frames are transmitted to arrive at the expected arrival time, ¶ 201: i.e. rendered accordance with the actual refresh rate of the client display).
Dimitrov does not specifically teach, wherein the delay … is computed by the user device based on a timing of the user device synchronizing frame generator.
Song (Figs. 2, 3) teaches, the delay corresponds to a timing (¶ 46: i.e. sync information received by interface 110 from the host device 200) of the display (display apparatus 100-1) and is computed by the display device based on a synchronizing frame rate generator (control unit 130) of the display device (¶ 58: i.e. control unit 130 produces information regarding the delayed time and calculate the amount of delay).
It would have been obvious to a person of ordinary skilled in the art before the effective filing date of the claimed invention to incorporate Song’s synchronizing method between the display device and the host device into Dimitrov’s display, so as to provide adjusted sync information to each of a plurality of display apparatus being used in conjunction with the tiled display system (¶ 15).
As to claim 9, Dimitrov (Fig. 1B) teaches, if a receipt time of the result is earlier than an adjusted time (i.e. frames E-I have been received early), delaying the first signal by an increment (¶ 66, 68: i.e. if a frame arrives early, buffered in jitter buffer 138 before being displayed by progressively increasing amount of time).
As to claim 10, Dimitrov (Fig. 1B) teaches, if a receipt time of the result is later than an adjusted time of the user device (expected arrival time 154), speeding the first signal by a decrement (¶ 64: i.e. rate greater than 60 fps, ¶ 72, 73: i.e. frame rate is increased to 60 or 120).
As to claim 11, Dimitrov (Fig. 1B) teaches,
if a receipt time of the result is about same as an adjusted time of the user device, maintaining the first signal without increment or decrement (¶ 110: i.e. when client indicates that the frames arrived in time, then the server device does not reconfigure the frame rate).
As to claim 12, Dimitrov (Fig. 1B) teaches, if a receipt time of the first signal is earlier than an adjusted time of the server computer, the server computer increments a timing signal for processing (¶ 112: i.e. frame rate is changed by changing frame timer 120, which may generate a signal interrupt or other signals, ¶ 66, 68: i.e. if a frame arrives early, buffered in jitter buffer 138 before being displayed by progressively increasing amount of time).
As to claim 13, Dimitrov (Fig. 1B) teaches, if a receipt time of the first signal is later than an adjusted time of the server computer, the server computer decrements a timing signal for processing (¶ 112: i.e. frame rate is changed by changing frame timer 120, which may generate a signal interrupt or other signals, ¶ 64: i.e. rate greater than 60 fps, ¶ 72, 73: i.e. frame rate is increased to 60 or 120).
As to claim 14, Dimitrov (Figs. 1A, 1B) teaches, if a receipt time of the input is about same as an adjusted time of the server computer, the server computer maintains the first signal without increment or decrement for processing (¶ 112: i.e. frame rate is changed by changing frame timer 120, which may generate a signal interrupt or other signals, ¶ 110: i.e. when client indicates that the frames arrived in time, then the server device does not reconfigure the frame rate).
Response to Arguments
