The container is referred to popularly as the wrapper format and involves the entire form of compression of a stream which needs to be stored within a particular file. It also derives the question of how much metadata requires being stored and whether a specific form of codification is actually required. The kind of format involved here is the Meta format and that goes in to the working of a container format which makes it so very effective and useful when any kind of data needs to be streamed into a particular file.
There are certain problems which have arisen out of this entire process because if a program can be involved in the identification and opening of a file then it might not eventually be able to decode the data stored within the file. It is also often likely that the software involved in the decoding is not capable of the specific decoding involved because of complicated methods of algorithm involved. Only in the process of a container, the software uses a complicated method which basically employs the process of “wrapping” around a data file and then converting it into some sort of file that can be worked upon.
Technically this wrapper format or file is designed to wrap all types of data files and the compression is carried out accordingly. There are plenty of different types of files that are like this. Multimedia formats in particular require this kind of wrap programming where so much of data and formatting is involved. They primarily require algorithms to function and the entire process involves the inclusion of a codec which is essential for carrying out the work of compressing the data.
Basically this kind of container format can include and supports work from audio and video. This basically means that the signals and streams formatted are both from audio as well as video files. The amount of meta data that is required is definitely mentioned in the specifications that come along with the entire file. Streaming of video and audio files, along with functionality of the Internet is also incorporated.
The parts which make up the container format come with different kinds of names. These specific names are even called “chunks” and “packets” and come with different types of extensions like PNG and RIFF. What make up these little parts of the file are the payloads which can be understood in terms of the definition of data. All of this information usually appears in a definite sequence and pattern which helps in storing enough information.
What are the different types of container formats?
There are several different types of container formats which can be taken into account while classifying them all:
Some of the container formats are used specifically for audio work. These file formats are used in different computer programs depending on what the computer is capable of. The computers which run on Mac OS use essentially different containers in comparison to what is used in a Windows computer. The AIFF container supports the IFF file formatting whereas the WAV works for RIFF format.
Of course there is essentially a difference between the file formats that work for the different types of audio and video media. There are specific containers which function for audio, video and still images. Some of the popular ones are:
There are several formations which do not necessarily give much information about the coding. But there are also several file formats which go on to mention the storage layer along with the coding involved in the wrapping of the file format. The best example for this is the JPEG wrapper format which is referred to as JFIF. The JFIF contains all the JPEG data along with the PNG data as well.
Technically speaking, professionals of computer science have the ability to change the coding done in a storage layer as is used in perhaps a PNG file format. The Multiple image Network Graphics , referred to basically as MNG makes use of the PNG container and at the same time also packs in works of animation.
It is essential that the container has to have a support system. Unless it has an extensive support base it’s likely that it will take some time for the container format to take off on a popular level.
Also it becomes relatively easy to distinguish how good each of them is in what they are doing depending on the kind of codec feature installed in it. It has to have to be able to support advanced media content which makes it easier for the user to have things work out.
It is also perhaps important to keep in mind that there are different types of container formats and each of them have their own definite specification which enables them to function for a specific kind of media. It is best to try one out for audio and video and decide on it’s overall functionality.
