Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application is a continuation of U.S. patent
application Ser. No. 11/237,435 (Attorney Docket No. 1459-VIXS084),
entitled "SYSTEM AND METHOD FOR DYNAMIC TRANSRATING BASED ON
CONTENT" and filed on Sep. 28, 2005, the entirety of which is
incorporated by reference herein.
[0002] The present application is related to co-pending U.S. patent
application Ser. No. ______ (Attorney Docket No. 1459-VIXS084C2),
entitled "DYNAMIC TRANSRATING BASED ON AUDIO ANALYSIS OF MULTIMEDIA
CONTENT" and filed on even date herewith.
[0003] The present application is related to co-pending U.S. patent
application Ser. No. 11/522,141 (Attorney Docket No.
1459-VIXS084C), entitled "SYSTEM AND METHOD FOR TRANSRATING BASED
ON MULTIMEDIA PROGRAM TYPE" and filed on Sep. 15, 2006.
FIELD OF THE DISCLOSURE
[0004] The present disclosure relates generally to data processing
and more particularly to processing multimedia information.
BACKGROUND
[0005] Current trends in multimedia content distribution are
directed to the storage of multimedia content for subsequent access
or distribution. Presently, many households utilize personal video
recorders (PVRs), also referred to as digital video recorders
(DVRs) to store multimedia content received from a terrestrial
broadcast as digital data. This data then may be accessed at a
later date for display or transmission to another device, such as a
cell phone or a portable video player. Current multimedia storage
solutions face a choice of either content quality or storage space.
As such, these conventional solutions either elect to
indiscriminately reduce content quality content, thereby reducing
the space required to store the data, or they elect to retain
content quality, thereby limiting the amount of data that may be
stored in a cost-effective manner. Accordingly, an improved
technique for processing multimedia data for storage or
distribution would be advantageous.

one embodiment of the present disclosure.
[0009] FIG. 4 is a flow diagram illustrating an exemplary method
for dynamic transrating in accordance with at least one embodiment
of the present disclosure.
DETAILED DESCRIPTION OF THE DISCLOSURE
[0010] The following description is intended to convey a thorough
understanding of the present disclosure by providing a number of
specific embodiments and details involving modifying multimedia
content based on one or more rule sets associated with content
characteristics. It is understood, however, that the present
disclosure is not limited to these specific embodiments and
details, which are exemplary only. It is further understood that
one possessing ordinary skill in the art, in light of known systems
and methods, would appreciate the use of the disclosure for its
intended purposes and benefits in any number of alternative
embodiments, depending upon specific design and other needs.
[0011] FIGS. 1-4 illustrate exemplary techniques for modifying
multimedia content based on rule sets associated with one or more
content characteristics. In at least one embodiment, multimedia
data representing, for example, a program is received. Based on
program information associated with the multimedia data, a rule
template is identified. The rule template includes one or more
rules, each rule being represented by, for example, a content
characteristic and one or more content actions associated with the
content characteristic. The rule template then is applied to the
multimedia data so as to modify the multimedia data. In one
embodiment, the rule template is applied by processing the
multimedia data using some or all of the applicable rules of the
rule template, where the multimedia content of the multimedia data
is analyzed to determine if the content characteristics of one or
more rules are present, and if so, one or more of the content
actions associated with the identified content characteristics may
be performed.
[0012] Referring to FIG. 1, an exemplary multimedia processing
system 100 is illustrated in accordance with at least one
embodiment of the present disclosure. As exemplary depicted, the
system 100 can include a multimedia processing device 102, a
content provider 104 and one or more storage devices 106. The
multimedia processing device 102, in one embodiment, includes a
transrater 110 and a rules template database. Implementations of
the multimedia processing device 102 may include, for example, a
set top box, a personal versatile recorder (PVR), a television
tuner card, a video card, and the like. The content provider 104
can include, for example, a satellite video feed, a cable
television head in, a digital versatile disk (DVD) drive, and the
like. The storage device 106 may include, for example, memory, a
hard disc, a DVD drive, and the like.
[0013] In operation, the multimedia processing device 102 receives
multimedia data 108 from the content provider 104, where the
multimedia data may be provide in, for example, an MPEG data stream
format. Program information 114 associated with the multimedia data
108 also can be provided with the multimedia data 108 or as a
separate transmission. The program information 114 provides an
indication or description of the programmatic details of the
multimedia data 108. To illustrate, the multimedia data 108 may
represent, for example, a particular football game and the program
information 114 therefore can identify the multimedia data
generally as a sports program, more particularly as a football
program, and more specifically as, for example, a NFL.RTM. football
program for a particular television network (e.g., Monday Night
Football.RTM.). The program information 114 can include electronic
program guide (EPG) information or information transmitted as
closed captioning information during vertical blanking
intervals.
[0014] Based on the program information 114, the transrater 110
identifies a particular rules template from the rules template
database 112 that is applicable to the program type of the
multimedia data 114. Using the example provided above, the rules
template selected may be a rules template that is applicable to
sports programs in general, a rules template that is applicable to
football games, or a rules template that is applicable to the
particular type of football game (e.g., a college football game or
a football game program provided by a particular television
network). After identifying the appropriate rules template, the
transrater 110 analyzes one or more portions of the content of the
multimedia data 108 to determine if one or more content
characteristics identified by the rules of the rules template are
present in an analyzed portion. To illustrate, the rules template
can include a rule that provides that if the analyzed content
portion includes a change in average audio volume that is greater
than a given threshold (one example of a content characteristic),
then the bit rate of the content portion is reduced by a provided
amount (one example of a content action). This rule may be
utilized, for example, to identify the presence of a commercial
(which often is preceded by a change in volume), and if so present,
the bit rate of the multimedia data representing the commercial
content may be reduced so as to reduce the overall amount of
multimedia data without materially affecting the multimedia content
of the program that a viewer is likely to care about (i.e.,
non-commercial content).
[0015] If the content characteristic of an applied rule is present
in the analyzed portion of the multimedia content, the transrater
110 may perform one or more content actions associated with the
rule with respect to the multimedia content. For example, using the
change-in-volume content characteristic described above, a
corresponding content action can include, for example, a reduction
in the bit-rate of the multimedia data representing the commercial
content. As a result, the data representing the commercial content
can be reduced without materially affecting the user's enjoyment of
the program because users typically do not pay as much attention to
commercials as they do the remainder of the program and the
commercials therefore do not need to be of the same or similar
quality as the rest of the program.
[0016] The transrater 110 thus can apply the rules template to the
multimedia data by analyzing the multimedia content of the data in
view of some or all of the rules of the template, thereby
generating modified multimedia data 116 from the received
multimedia data 108. The modified multimedia data 116 then may be
provided for storage in the storage device 106 for subsequent
access.
[0017] Referring to FIG. 2, another exemplary multimedia processing
system 200 is illustrated in accordance with at least one
embodiment of the present disclosure. As illustrated, the system
200 includes the multimedia processing device 102 having an input
connected to a storage device 206 and an output connected to at
least one multimedia device 210 via a network 204. In the
illustrated example, the transrater 110 may access multimedia data
208 stored in the storage device 206, identify the appropriate
rules template from the template database 112 using program
information 214 associated with the multimedia data 208, and apply
the identified template to the multimedia content of the multimedia
data 208 to generate modified multimedia data 216 as described
above. Further, in addition to, or instead of, providing the
modified multimedia data 216 for storage in a local storage device,
the modified multimedia data 216 may be transmitted for storage in
the multimedia device 208 via the network 204, where the network
204 may include, for example, a wireless network, the Internet, a
universal serial bus (USB), and the like. Accordingly, the modified
multimedia data 216 subsequently may be accessed by the multimedia
device for processing for display or for transmission to another
device.
[0018] It will be appreciated that data storage limitations of the
multimedia device 210 and/or bandwidth limitations of the network
204 may require additional consideration when transrating the input
multimedia data 208 to generate the output modified multimedia data
216 so as to comply with these limitations. Accordingly, in at
least one embodiment, the template database 112 may include
templates indexed not only by, for example, program type, but also
by one or more characteristics of the multimedia device 210 and/or
the network 204. For example, a given news program may have a
plurality of different rules templates that can be applied, where
some rules templates are directed to portable multimedia devices
that have limited storage and other rules templates are directed to
multimedia devices or storage devices that have less limited
storage or higher-bandwidth network connections. Those rules
template directed to portable device can have, for example, rules
that have more aggressive data-reducing content actions, whereas
those rule templates directed to high-capacity devices can have,
for example, rules that are less aggressive with respect to
data-reduction and focus more on total image quality.
[0019] Table 1 below provides a non-limiting list of exemplary
rules used to process the content of multimedia data.

[0020] Referring to FIG. 3, an exemplary implementation of the
transrater 110 of FIGS. 1 and 2 is illustrated in accordance with
at least one embodiment of the present disclosure. The exemplary
transrater 300 includes a rules table identifier module 302, a
rules table buffer 304, a content analyzer 306, an input data
buffer 308, a transcoder 310, an output data buffer 312, a system
layer formatter 314 and an indexer 316.
[0021] In operation, multimedia data 322 is received and buffered
in the input data buffer 308. Program information 324 associated
with the input multimedia data 322 is provided to the table
identifier module 302. Based on the program information 324, the
table identifier 302 indexes the rules table database 112 to
identify an appropriate rules table 326 to apply to the incoming
multimedia data 322. The identified rules table 326 can be provided
for storage in the table buffer 304 for use by the content analyzer
306. Alternately, an indicator (e.g., an address or pointer) to the
identified rules table 326 may be provided to the content analyzer
306.
[0022] In at least one embodiment, the table identifier 302 has
access to electronic programming guide (EPG) information 318 so
that the table identifier 302 may identify one or more program
types of the incoming multimedia data 322 and identify the rules
table 326 accordingly. In at least one embodiment, multiple rules
tables may be appropriately applied to the multimedia data 322. In
such instances, the table identifier module 302 can select the more
appropriate template to apply to the multimedia data 322, where the
more appropriate template typically is the template aligned with
the most specific program type. For example, the EPG information
318 may identify the incoming multimedia data 322 as being
associated with a sports program in general and a soccer game
program specifically. The table identifier module 302 therefore may
identify a rules template associated with soccer game programs in
particular. If such template is not available, the table identifier
module 302 alternatively may select a rules template associated
with sports programs in general.
[0023] Moreover, in one embodiment, when no rules template is
identified based on specific program information, the table
identifier 302 may select a default rules template. For example, if
the multimedia data 322 represents a news broadcast from a
particular television network for which there is no corresponding
rules template in the template database 112, the table identifier
module 302 may select a default template that may be generally
associated with, for example, the type of multimedia device 210
that is expected to receive the resulting modified multimedia
data.
[0024] An exemplary implementation of the rules template 326 is
depicted by FIG. 3. As illustrated, some or all of the rules
templates of the template database 112 may include one or more
rules (e.g., rules entries 330-333, also identified as Rule 1-Rule
N), each rule having a content characteristic descriptor (e.g.,
content characteristic descriptors CC.sub.1-CC.sub.N for rule
entries 330-333, respectively) and one or more content action
descriptors (CA) associated with each content characteristic
descriptor. The content characteristic descriptors typically
represent a content characteristic which, if found in an analyzed
content portion, results in the performance (or the avoidance of
the performance) of one or more content actions represented by the
one or more content action descriptors. The content characteristic
descriptors typically include information describing a
characteristic of the multimedia content (such as, for example, a
descriptor indicating that if an optical character recognition
analysis of the top portion of successive frames indicates that the
score of a game has changed). The content characteristic
descriptors may include, for example, microcode, a pointer to a
memory location storing a routine for performing the one or more
content actions, or information used in processing the multimedia
data (such as, for example, a quantization scaling factor or a
resolution scaling factor to be applied by the transcoder 310).
[0025] Each rule further may include a link field 336 to indicate
if the rule is linked to any other links and a link type field 338
to indicate the type of link (e.g., an AND relationship or an OR
relationship). For example, Rule 1 may be linked to Rule 2 in an
AND relationship whereby if the content characteristic of Rule 1 is
found the content characteristic of Rule 2 also must be found
before the content actions of Rule 1 can be performed. As another
example, Rule 1 may be linked to Rule 2 in an OR relationship
whereby if the content characteristic of Rule 1 is identified as
present in the analyzed content portion, Rule 2 is not to be
applied to the content portion.
[0026] Although the exemplary rules described above have a
condition (the presence of the content characteristic) before the
corresponding one or more content actions can be performed, in at
least one embodiment one or more of the rules may be unconditional
rules whose content action(s) are always performed without a
corresponding condition being met. For example, for multimedia
content representing a new program, the image portion of successive
frames that represents, for example, a stock ticker can be
transrated so as to automatically reduce the image portion's
resolution with an analysis of the content of the image
portion.
[0027] The content analyzer 306, in one embodiment, analyzes the
multimedia content of the multimedia data 322 in view of some or
all of the rules of the rule template 326. Accordingly, in one
embodiment, the content analyzer 306 obtains rule information from
the table buffer 304 (or, alternatively, from the template database
112 directly) and analyzes the content of the multimedia data 322
to determine if content characteristics associated with the applied
rules are present in one or more portions of the multimedia
content.
[0028] In some instances, the content analyzer 306 can analyze the
multimedia data 322 for certain content characteristics while the
multimedia data 322 is in encoded form. To illustrate, an exemplary
content characteristic to be identified can be an amount of motion
between successive frames that is greater than a certain threshold.
In this case, the content analyzer 306 may analyze, for example,
the motion vector information of the encoded multimedia data 322 to
determine if there is substantial motion between image frames.
However, in other instances, identifying certain content
characteristics can require that the multimedia data 322 be in
decoded form. For example, in one embodiment the content
characteristic may be the identification of the word "goal" in the
audio content of the multimedia data 322. In this case, the content
analyzer 306 typically would access decoded audio information to
perform an audio analysis for the word "goal". Accordingly, the
transcoder 310 may decode some or all of the multimedia data 322
and store the decoded multimedia data in a frame buffer 340
(exemplary illustrated as part of the data buffer 308). The content
analyzer 306 then may access the decoded multimedia data in the
frame buffer 340 to perform the content analysis.
[0029] The portion of the content of the multimedia data 322
analyzed for any particular content characteristic typically is
dependent on the particular characteristic. To illustrate, the
content characteristic of a change in displayed text representing,
for example, a score or a stock value may be identified by an OCR
analysis of a certain segment of two successive image frames. Thus,
the content portion for this characteristic would be two or more
frames. As another example, the content characteristic may be the
presence of a yellow line indicating the line of scrimmage in a
football game. In this instance, the yellow line may be detected by
analyzing a particular portion of a single image frame (e.g., the
center column of an image frame). In this case, the analyzed
content portion can include the center column of the image
frame.
[0030] In the event that the content analyzer 306 detects that a
content characteristic of a rule is present in an analyzed portion
of the multimedia data 322, the content analyzer 306 provides the
transcoder 310 an indication of the one or more content actions to
be performed. The transcoder 310 then processes some or all of the
multimedia data 322 in accordance with the content actions to
generate modified multimedia data 342. The multimedia data 342 then
may be stored in the outgoing data buffer 312 before it is
formatted for transmission as, for example, an MPEG program stream
346 by the system layer formatter 314.
[0031] In at least one embodiment, a content action to be performed
includes embedding a content characteristic index in the modified
multimedia data 342, where the content characteristic index
identifies the corresponding portion of multimedia data 342 as
representing multimedia content having the indicated content
characteristic. For example, the content analyzer 306 may analyze
the audio content of the multimedia data 322 to identify rapid
increases in the average volume of the audio. In the event that
such an average volume increase is found, the corresponding content
action can include inserting a content characteristic that
identifies the multimedia data portion representing, for example,
the next thirty seconds of content as a commercial. Thus, the
multimedia data 342 subsequently can be rapidly searched to
identify the data associated with commercial content and this
content may be filtered by, for example, removing the commercial
content, reducing the audio volume of the commercial content,
reducing the resolution and/or bit rate of the commercial content,
and the like. Alternately, the content action can include the
creation of a separate index table to a location of the commercial
content.
[0032] Accordingly, upon identifying a content characteristic
present in a portion of the multimedia content that has a
corresponding content index action, the content analyzer 306 may
provide index information to the indexer 316 which then manages the
insertion of the appropriate content characteristic index into the
multimedia data 341 using, for example, the system layer formatter
314.
[0033] Referring to FIG. 4, an exemplary dynamic transrating method
400 is illustrated in accordance with at least one embodiment of
the present disclosure. The method 400 initiates at step 402
whereby multimedia data is received and temporarily buffered. At
step 404, the appropriate rules template for the multimedia data is
selected based on program information, such as, for example,
program type, associated with the multimedia data. As noted above,
there can be a number of rules templates appropriate for
application to the multimedia data. In such instances, the rules
template more aligned with the program characteristics (e.g., a
rules template specifically for a football game rather than a
general sports program template) is selected. In the event that a
specific rules template is not available or appropriate, in one
embodiment a default general rules template may be selected.
[0034] At step 406, a rule from the selected rules template is
accessed and a portion of the content of the multimedia data is
analyzed to determine whether the content characteristic associated
with the rule is present in the analyzed content portion. If the
content characteristic is not present in the analyzed content
portion, the method 400 continues to step 410. Otherwise, when the
content characteristic is present, one or more of the content
actions associated with the rule are performed at step 408. In one
embodiment, rules may be linked using logical operations such as
AND operations and/or OR operations. Accordingly, if so linked, the
content actions of the rule may not be performed at step 408 until
the conditions of other linked rules are confirmed.
[0035] At step 410 the rules template is checked to determine if
the last rule to be applied has been applied. If not, the method
400 repeats steps 406-410 for the next rule to be applied. If it is
determined at step 412 that content portions of the multimedia data
have yet to be analyzed, the method 400 repeats steps 406-410 to
