Claim Rejections - 35 USC § 102
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 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims are rejected under 35 U.S.C. 102(a1) and (a2) as being anticipated by et al. ()
1. A method, comprising:
obtaining a change trend of an available channel capacity on a first channel, wherein the first channel is used to transmit video data;
“[0075]…As signal quality of the wireless network A is changed, a capacity of the channel A is also changed. When the signal quality of the wireless network A is poor, the capacity of channel A also deteriorates. For example, when a signal of the wireless network A is good, the capacity of a channel A is m. When a signal of the wireless network A is poor, the capacity of the channel A may be decreased to n, where m>n. When the capacity of the channel A deteriorates because the signal of the wireless network A is poor, when the video transmit end 100 transmits the video data in the wireless network A, an available channel capacity of the video transmit end 100 on the channel A is decreased.”
adjusting, based on the change trend of the available channel capacity, a quantity of layers during layered coding of at least one frame of data in the video data;
“[0043] In embodiments, processor 236 includes multiplexer 234 configured to combine an encoded base layer and an encoded enhancement layer, or progressive stream, to generate an encoded game frame. According to embodiments, multiplexer 234 is configured to truncate an encoded enhancement layer, or progressive stream, based on a target bitrate for the game stream 108.”
performing layered coding on the at least one frame of data based on a quantity of layers obtained after adjustment; and
‘[0044]…To facilitate transmission of the set of frames 405 to the client system executing the gaming application, wavelet transformer 226 performs a discrete wavelet transform 425 on each frame of the set of frames 405 to decompose the frames into respective base layers 430 and enhancement layers 435. Before multiplexer 234 combines together these respective base layers 430 and enhancement layers 435 to produce the encoded frame 460, the multiplexer 234 truncates the encoded enhancement layer to decrease the size of the resulting encoded frame. In doing so, the amount of bandwidth needed to transmit the encoded set of frames to the client system is reduced while maintaining visually important details from the enhancement layer.”

2. The method according to claim 1, wherein adjusting, based on the change trend of the available channel capacity, the quantity of layers during layered coding of the at least one frame of data in the video data specifically comprises: in response to the available channel capacity trending to decrease, increasing the quantity of layers during layered coding of the at least one frame of data; and
