Abstract
Abstract A video data stream is re-encoded using motion vectors from a prior encoding operation. The video data may be enhanced by the system. Information about the enhancement, along with the decoded motion vectors, is sent to encoding circuitry. Information provided to the encoder may be tailored to the type of video data received or to the type of enhancement performed, or based on other criteria. Using the previously derived motion vectors, the encoding circuitry may perform substantially fewer computations than are used to calculate motion vectors from scratch

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
46 words
A method comprising: decoding a compressed video stream to generate a decoded content portion and a first motion vector portion; modifying the decoded content portion; and encoding the decoded, modified content portion using the first motion vector and information about how the content portion was modified.
Claim 2
Independent Claim
46 words
A method comprising: decoding a compressed video stream to generate a decoded content portion and a first motion vector portion; modifying the decoded content portion; and encoding the decoded, modified content portion using the first motion vector and information about how the content portion was modified.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein modifying the decoded content portion includes adding graphic overlays and resizing the image.
Claim 4
Dependent Claim
41 words
The method of claim 1 including receiving compressed television content, decompressing the compressed television content, enhancing the decompressed television content, and encoding the enhanced television content using information derived from decoding the information and information about how the content was enhanced.
Claim 5
Dependent Claim
25 words
The method of claim 1 further comprising: modifying the first motion vector into a modified motion vector portion based upon the modified, decoded content portion.
Claim 6
Dependent Claim
29 words
The method of claim 4 further comprising: combining the modified, decoded content portion with the modified motion vector portion to form a video stream; and encoding the video stream.
Claim 7
Dependent Claim
45 words
The method of claim 1 , wherein modifying the first motion vector further comprises: receiving a modification operation; deriving a second operation from the modification operation; and performing the second operation on the first motion vector portion to arrive at a second motion vector portion.
Claim 8
Dependent Claim
27 words
The method of claim 6 , further comprising: testing the modified motion vector portion; and adjusting the modified motion vector portion as a result of the testing.
Claim 9
Dependent Claim
16 words

Claim 12
Independent Claim
60 words
A system comprising: a decoder to decode a compressed video stream to generate a decoded content portion and a first motion vector portion; a controller coupled to modify the decoded content portion; and an encoder coupled to said controller to encode the decoded, modified content portion using the first motion vector and information about how the content portion was modified.
Claim 13
Independent Claim
60 words
A system comprising: a decoder to decode a compressed video stream to generate a decoded content portion and a first motion vector portion; a controller coupled to modify the decoded content portion; and an encoder coupled to said controller to encode the decoded, modified content portion using the first motion vector and information about how the content portion was modified.
Claim 14
Dependent Claim
38 words
The system of claim 11 , further comprising: a memory storing the first motion vector portion and the information about how the content portion was modified; and an enhancer to perform enhancement operations on the decoded content portion.
Claim 15
Dependent Claim
19 words

Claim 16
Dependent Claim
23 words
The system of claim 12 , wherein the enhancement operation is an addition of a graphic overlay pattern on the decoded content portion.
Claim 17
Dependent Claim
20 words
The system of claim 12 , wherein the enhancement operation is a scrolling operation performed upon the decoded content portion.
Claim 18
Dependent Claim
58 words
An article comprising a medium storing instructions that when executed caused a processor-based system to: decode a compressed video stream to generate a decoded content portion and a first motion vector portion; modify the decoded content portion; and encode the decoded, modified content portion using the first motion vector and information about how the content portion was modified.
Claim 19
Dependent Claim
58 words
An article comprising a medium storing instructions that when executed caused a processor-based system to: decode a compressed video stream to generate a decoded content portion and a first motion vector portion; modify the decoded content portion; and encode the decoded, modified content portion using the first motion vector and information about how the content portion was modified.
Claim 20
Dependent Claim
25 words
