Puffer is a free and open-source live TV research study operated by Stanford University to improve video streaming algorithms. The study allows users across the United States to watch seven over-the-air television stations broadcasting in the San Francisco Bay Area media market for free.
Even on fast networks like LTE 4G, slow start times and re-buffering will occur during times of congestion or high network utilization. If the chosen bitrate is low, on the other hand, the video quality will be lower – thereby reducing the customer’s quality of experience. There are a number of ways of dealing with these challenges.
The amount of MPEG-2 stream buffer required at the decoder (the vbv_buffer_size_value) must be less than or equal to 999,424 bytes. In most cases, the transmitter can't start sending a coded image until within a half-second of when it's to be decoded (vbv_delay less than or equal to 45000 90-kHz clock increments).
Streaming television is the digital distribution of television content, such as and films and television series, streamed over the Internet. [1] Standing in contrast to dedicated terrestrial television delivered by over-the-air aerial systems, cable television, and/or satellite television systems, [2] streaming television is provided as over-the-top media (OTT), [3] or as Internet Protocol ...
This list of broadcast formats is a review of the most popular formats used to broadcast video information over cable television, satellite television, the Internet, and other means. Video broadcasting was popularized by the advent of the television during the middle of the twentieth century.
HTTP-based streaming protocols such as HLS and DASH typically use a segment-based approach. This means a video is cut up into TCP segments of a few seconds each, which requires video players to wait until the start of a new segment to start playback. This approach increases channel change times and introduces additional latency.
DASH is an adaptive bitrate streaming technology where a multimedia file is partitioned into one or more segments and delivered to a client using HTTP. [15] A media presentation description (MPD) describes segment information (timing, URL, media characteristics like video resolution and bit rates), and can be organized in different ways such as SegmentList, SegmentTemplate, SegmentBase and ...
This shows that one of the largest entertainment companies was willing to adopt to a live streaming/internet video model in order to support their business. Many other companies such as BBC (with iPlayer), ITV (with ITV Player) and Channel 4 (with 4oD) have made use of internet video to allow users to livestream content, or watch on demand later.
