Abstract
Abstract A video signal encoding system includes a signal processor for segmenting encoded video data into transport blocks having a header section and a packed data section. The system also includes reset control apparatus for releasing resets of system components, after a global system reset, in a prescribed non-simultaneous phased sequence to enable signal processing to commence in the prescribed sequence. The phased reset release sequence begins when valid data is sensed as transiting the data lines.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
A video signal encoding system comprising: means responsive to a video signal for providing encoded video signal data; signal processing means, including a plurality of signal processing components, responsive to said encoded video data for providing segmented transport blocks of video data comprising groups of packed data and headers identifying associated ones of said groups, said components subject to exhibiting a reset condition wherein normal signal processing operation is inhibited, and exhibiting said normal operation when said reset condition is released; and resetting means coupled to said signal processing means for causing certain ones of said components to exhibit said reset condition; wherein said resetting means releases said certain components from said reset condition in a prescribed non-simultaneous sequence such that said certain components are uninhibited in said prescribed non-simultaneous sequence, respectively, to thereby exhibit normal operation in said non-simultaneous sequence.
Claim 2
Dependent Claim
141 words

Claim 3
Dependent Claim
22 words
Apparatus according to claim 1, wherein said resetting means releases said reset condition in response to the appearance of image representative data.
Claim 4
Dependent Claim
21 words
Apparatus according to claim 2, wherein said image data represents intraframe image data which alone is sufficient to produce an image.
Claim 5
Dependent Claim
33 words
Apparatus according to claim 1, wherein said resetting means resets said certain components simultaneously, and releases said reset condition in said prescribed sequence to enable signal processing to commence in said prescribed sequence.
Claim 6
Dependent Claim
63 words
Apparatus according to claim 1, wherein said certain components of said signal processing means comprises: data means responsive to encoded video data for providing groups of packed video data; header means for generating transport headers identifying associated ones of said groups of packed video data; and means for combining a transport header with an associated packed data group to produce a transport block.
Claim 7
Dependent Claim
73 words
Apparatus according to claim 5, wherein a reset condition of said header means is released before a reset condition of said data means is released whereby said header means is uninhibited to allow normal operation before said data means; and a reset condition of said data means is released before a reset condition of said combining means is released whereby said data means is uninhibited to allow normal operation before said combining means.
Claim 8
Dependent Claim
111 words
Apparatus according to claim 6, wherein said resetting means provides a first control signal to said header means, a second control signal to said data means, and third and fourth control signals to said combining means; said combining means includes first storage means for receiving said headers, and second storage means for receiving packed data groups; and means for conveying header data from said first storage means and packed data from said second storage means to an output; wherein said first storage means is released from a reset condition prior to said second storage means whereby said first storage means is uninhibited to allow normal operation before said second storage means.
Claim 9
Dependent Claim
22 words
Apparatus according to claim 7, wherein said first, second, third and fourth control signals release a reset condition in the order named.
Claim 10
Dependent Claim
20 words
Apparatus according to claim 1, wherein said video signal is a video signal component of a high definition television signal.
