Information Processes in Multimedia

posted Jul 8, 2009, 5:35 PM by Unknown user   [ updated Jul 16, 2009, 6:23 AM by Eddie Woo ]
The components of my website that promote LOTE would include: the front page, the video, the audio, the languages' front pages, the French excursion & Japan trip pages, & the ______ Study @ JR pages.
Information displayed on the site (excluding attachments)
This data is mostly text, but also includes the small amount of numerical data that is incorporated into the text, as well as images that have been added onto the website (Japan photos excluded).
  • The information from the subject selection sheets & booklet were put onto the site (this included text & numerical data).
  • Images that were put around the site were either collected with the camera, or copied from another website.
  • The layout of the different elements of the page were changed around for consistency and easier use.
  • Some of the text paragraphing was changed so that it fit better on the page.
  • Images were organised as .JPG by the camera.
  • Images were resized so that they would fit better on the page, &/or be less of a problem for slow Internet connections.
  • Hyperlinks were made to link relevant data & assist navigation, including links from thumbnails to the original pictures. It also made categorising data into pages possible.
  • The pages were named according to the data each contained.
  • The images were labelled according to what they were of (except for the Eiffel Tower), & if they led to another page (that was not the source page), that was also labelled.
  • Data about the camera were attached to the image, and the time of collection was added to the corner of the image.
Storing & Retrieving
  • The text data was stored on paper before it was put onto the Intranet.
  • A backup copy of the files were also created and stored on other storage devices.
  • The images from the Internet were stored on their web servers, & were retrieved when they were accessed. The image would have been temporarily stored on the computer for display. Some of the images collected from the websites were stored on the computer before being put on the Intranet.
  • Other images that were collected by the camera would have been stored in the camera after collection.
  • All the data are stored on the the web server for the Intranet, & there is retrieving every time a participant or end user accesses the data.
  • The text data were added onto or removed from various pages, and they were edited to remove errors & add more data that were collected later.
    • There could have been some problem with my computer (or the software on it) & the website as there were a few times when Internet Explorer windows stopped responding or automatically closed.
  • The camera added the date of collection to the corner of the collected photograph.
  • Some images that did not need to be big or very good quality were cropped so that it could be more easily added to the pages.
  • Images were added to the pages.
  • Hypertext was created to link pages. Links to other external websites were also made.
  • Pages were created, & parts of the pages on the portfolio were edited (to add text & image data).
  • The names of the URL were changed.
Transmitting & Receiving
  • There would be transmitting & receiving between the computer and the web server whenever parts of the multimedia system were accessed.
    • There was transmitting & receiving when the images on other websites were accessed.
    • There would have been transmitting & receiving when all the data were put onto the website.
  • The images taken by the camera were moved to the computer.
  • There was transmitting & receiving when an end user told me about some of the errors on the site.
  • The text data for subject promotion were displayed on paper.
  • Images taken by the camera were displayed by the camera screen after collection.
  • The data were displayed on the computer VDU when it was collected into the computer, & they were displayed by the VDU whenever they were accessed.
Japan trip & French excursion data
These were mostly image data, but there are some text & numerical data as well (such as the headings & the short 'introduction')
  • Images were collected using a camera from Japan on the Japan trip.
  • Data (including student numbers & visited locations) about the trip were collected from the itinerary, as well as other sources during the trip.
  • The French excursion photographs were uploaded by Blair onto Picasa, & there was collection when those were downloaded onto the computer.
  • The camera organised the images into .JPG files after collection.
  • Video clips (although none were actually used) were organised into .MOV files by the camera after collection.
  • The layout of the page was changed.
  • The text was paragraphed so that it was easier for the end users to read, and the 'recount' was also put in a blockquote so that it was more distinguished from the rest of the text.
  • The thumbnails were linked to the original images.
  • The images were put under headings (including day of the trip & locations) so that the people knew where & approximately when the pictures were taken.
  • The headings were also arranged chronologically so that people had a better of idea of what the Japan Trip itinerary was like and how much was covered in a day.
  • There were other data attached to the images - most importantly (for this project) the date of collection.
  • One photograph (Splash Mountain, Tokyo Disneyland) was given a label so that people knew what it was about (it was the only picture not under a heading...although there is a smaller version of the picture that is under the Disneyland heading)
  • A short sentence about the French trip was put on the excursion page so that people knew what the photographs were about.
  • The pages were named so that people knew what the page was about even before going there.
Storing & Retrieving
  • Image & video data was stored on the camera immediately after its collection.
  • Images & text that arrived by email were stored on the mail server, & were retrieved when they were accessed.
    • The images were also stored onto the computer before being uploaded onto the website.
  • One student gave me images through an SD card - the images were stored on the SD card, & I had to retrieve them off it.
  • A copy of all the Japan trip images were stored onto a USB.
    • This was supposed to serve as a backup, but turned out to help in another way - the pictures could be uploaded from school (which was, for some reason, much faster & more effective at it)
  • French pictures were stored on the Picasa server, & there was retrieving when I accessed them.
    • The photograph was also stored temporarily on the computer when I retrieved it to view.
  • All the data on the website are stored on the web server & being retrieved every time an end user accesses them.
    • There was some problem with uploading photos at home (they did not show up, or they were too slow, or they just did not upload at all). This was fixed by uploading the photos at school, except there were very long file names as a result.
  • When an image was uploaded onto the Intranet and the 'S' was clicked for the full-sized image, a thumbnail was automatically created.
  • Hyperlinks were created from the thumbnail to the original image.
  • The page was processed when the headings & other data were added.
  • Page names were edited & the URLs were changed.
Transmitting & Receiving
  • Images that I collected were passed from the camera onto the computer.
  • There would have been transmitting & receiving between the computer & the SD card when the images were taken off it.
  • Some other people in the environment & end users sent images by email to be uploaded onto the website.
  • There would have been transmitting & receiving between the computer & the web server when all the data were uploaded.
    • There would have been transmitting & receiving between the USB & the school computer when some of the images were uploaded directly from the USB.
  • The recount was sent to by email.
  • There was transmitting & receiving when I asked Blair for details on the French excursion.
  • When the images were collected, they were displayed on the camera screen.
  • These were displayed by the VDU once all the data were moved onto the computer &/or the website.
  • Audio data (mostly interviews) were recorded using the MP3.
    • There were some 'junk' bits that the MP3 recorded at the start and beginning of a lot of the video clips. They could have been removed using Windows Movie Maker and exported again as audio files, but the only file type that was available for this was .WMA, which cannot be converted back to .MP3 with the available software.
      • Although the .WMA files were not extremely large (at least not to me) & did not cause any significant problems, I could not be sure if that would be the same case for all other users of the system.
  • Audio data files were converted from .WMA to .MP3 - compression for distribution (in this case, on the Intranet)
  • The file was organised into .WMA when the audio was published from Windows Movie Maker (the file was not used).
  • The appropriate file names were given to the recordings.
  • It was mentioned (on whichever page the interview was uploaded on) that the interviews were with students/teachers of the language.
Storing & Retrieving
  • The recorded audio data was stored as .WMA on the MP3 after collection.
  • The .MP3 file that it was converted to was stored back onto the MP3.
  • The .MP3 file was stored onto a USB through the school computer.
  • The final file was uploaded from the USB onto the Intranet & stored on the web server through the home computer.
  • The useless bits at the start & end of the were removed, except the file produced was not used.
Transmitting & Receiving
  • The audio files were moved onto Mr Woo's computer when he converted them, & compressed files were moved back into the MP3 when he had finished.
  • There was transmitting & receiving when the files were moved from the MP3 onto the USB through the school computer.
  • There would have been transmitting & receiving when the audio files were uploaded onto the Intranet.
  • The audio recordings were displayed on the MP3 just after they were made.
  • After they were put onto the computer, they were displayed by the speakers on the computer.
The parts of the video were separately collected (& were in different media), although all the data were combined into a video as the final product.
  • Some images were created for the video. Some of the images were screenshots of a website.
    • There were hardware constraints as the computer was unable to process the amount of image data that I was dealing with, & so that was very limiting as to how many images I could make in a certain amount of time.
    • The screenshots were used to replace the clip of surfing German Wikipedia mentioned below.
  • Video data were recorded using a camera. There would have been analogue-to-digital conversion involved.
    • There was a part when I tried to film someone surfing German Wikipedia. There were some hardware constraints - the camera was not very good, & so it did not show up very well. Also, I did not use a tripod (it would have been hard to use one then), so that part of the shakes a lot. It shook at other parts too, but was a lot more noticeable at that part. This was not used in the final video product - it was replaced by the series of screenshots.
  • The images were organised as bitmap images by the graphics software, & later organised into .JPG files when they were saved. Relatively high quality .JPG images were made (put on 95 [software default] on a scale of 100) - as the final video product would be compressed during publishing, I did not want to lose to much data in the earlier stages.
  • Immediately after collection, the audio files were stored as .WMA files on the MP3.
  • The .WMA file was organised into an .MP3 file (compression occurred there).
  • Immediately after collection, the video files were organised as .MOV files by the camera.
  • Files were saved (still in editing stages) as .MSWMM files by Windows Movie Maker (from the small size of the file [1.01MB] and the mention of 'source files' when editing the project [& the disappearance of the data when the source files were moved], though, I do not think this file actually holds the video data).
  • Finally, they were published as .WMV files - organised in a way that can be stored as a separate file with all the required data & displayed. The level of compression would have been quite high - the setting for the best quality video for 'this' computer playback rendered a file of 8.71MB (the uploaded file was 2.47MB).
    • The file was published many times, each time set to compress to a different file size.
  • There was compression with the publishing. The video quality was worse than the original (frame rate was greatly reduced, & although the audio was not significantly worse, the bit rate was reduced), & was also resized - the playback area was a lot smaller for the finished product. Both help to produce a smaller file.
  • All the images that were used in the video were given names that described what they were of & their order - this made it a lot easier to place them onto the video timeline in the correct order.
  • The various video & audio recordings taken for the video were also named so that the file could be easily identified & found.
  • The appropriate file name was given to the final video product - this made its purpose clearer, & the video also becomes easier to find & identify
  • The purpose was also made clear by the image that was put at the start of the video.
    • Although adding the image to the video should be part of processing because the file has been changed. However, the data that was intended to be in the original video has not been changed, so the image would have more of an analysing purpose.
  • The camera attached some of the information about the video to the file, including information like 'date taken'. The data about the final videos were automatically attached to it (including: frame rate, bit rate, file size, etc.)
Storing & Retrieving
  • Other images were created & stored on the computer (screenshots were also taken & stored on the computer). When the website (for the screenshots) was accessed, the data would also have been temporarily stored on the computer.
  • The recorded audio data were stored as .WMA files immediately on the MP3 after collection. The converted files were also stored back onto the MP3, & these were moved onto a USB. Some audio data were recorded using the camera & stored on there as .MOV files.
    • Audio data recorded with the camera have some buzzing noise in the background, probably due to internal processes that were happening in the camera at the time of recording. However, speaking louder allowed the volume to be turned down a little so that the buzzing sound was not as obvious.
    • For the part where Blair spoke French, I recorded that with the MP3 because I did not need a video of him, so there was no noise there.
  • The audio data were moved onto the computer & stored to be incorporated into the video.
  • The recorded video data was stored on the camera after collection, & later were moved onto the computer & stored.
  • Each time the video was published, a copy of it was stored on the computer.
  • I also sent the video to others to see if it worked & for some feedback, so the video would have been stored on the mail server.
  • The final video product was stored on the web server for the Intranet, & every time it is downloaded, there would be retrieving.
  • Images were edited for use on the video (mostly cropping [the screenshots were cropped so that they were closer to the 4:3 aspect ratio]...although there are also bits that were edited [like making the stick figure wave & the plane 'draw lines'])
    • Cropping each individual screenshot would have been a long process & I could not be sure that screenshots would be lined up properly, so I put them all into one file (.PDN, which is used by the graphics software) in different layers & resized the whole image. This cropped all the screenshots in one go except there was a lot of image data, so the computer was very slow at doing that.
  • In creating the video, parts of the audio were cut and other were edited (start & ends of the audio were cut to remove useless data, & one video was split so that one half could be sped up without affecting the other half) to make the final product. The duration of images were shortened to make the video smoother. Various elements of the video were rearranged so that the timing with the audio & 'animation' worked out. The audio recorded by the camera had the 'animation' component removed.
    • There was some difficulty layering the various parts of the video (especially audio), as Windows Movie Maker only supplies one row for each medium, so some of the planned effects were not included with the final product.
    • Control of the duration seemed to be limited to changing the length of the image/video on the timeline (done by clicking & dragging), & the shortest duration that could be achieved this way was 0.08 seconds. This made the movement a little choppy in parts of the original planned video, except the parts which had this problem were cut in the final video.
    • There would have been data thrown away in the final product as the frame rate was much lower, but this was a lot more noticeable in the faster parts of the video, where the movement became very choppy.
  • When the file was sent by email, there would have been processing when the video data was changed into text data.
Transmitting & Receiving
  • When I accessed the website, there would have been transmitting of data & my computer would have received the website.
  • The audio collected from the camera & the MP3 were move from the collection devices onto the computer.
  • When the .WMA files on the MP3 were converted into .MP3, there would have been transmitting & receiving between the computer & the MP3. The converted files were also moved back onto the MP3.
  • The video files on the camera were moved onto the computer.
  • The video file was sent to some other people, & they gave some feedback on it.
  • The final video file was uploaded onto the Intranet.
  • The video recordings would be displayed on the camera & its speakers after it has been recorded.
  • They were moved onto and displayed on the computer VDU & speakers.
    • There are issues with viewing YouTube videos at school, but this option was not chosen & the video was just uploaded as an attachment to the page, so this should work at school.
