Digital television signals allow files to be compressed, and because of this it has changed broadcasting radically. It has made things such as editing, television, and storing files better. The allowance of being able to compress files means that media files can now be put on smaller devices such as phones e.g. Files such as movies can be compressed and put on 8GB IPods, phones and portable MP4 devices. TV has changed for the better as well, as we are now able to receive more than the 5 standard terrestrial channels on TV, which is transmitted on one bandwidth which uses a multiplex. The quality of picture and sound has improved significantly, although some may argue that point. Sound and picture quality has been enhanced due to files not loosing there quality when compressed so that it can be put on other devices such as DVD’s. Blue ray discs have more storage capacity and so can store a higher quality of video.
Digital television signals has created a long path for more and better technology to come out, which is beneficial for audiences and consumers. It has allowed broadband which has lead to internet TV, we can pause and record live TV when it suits us, and we can have media on our phones.
